[Detailed Description of the Invention]
[Field of the Invention] The present invention relates to the device which can be applied to the inside of the blood vessel of the body of an animal live, for example or a living human being. This device could be made to expand to the 2nd state of a larger diameter from the 1st state of a predetermined diameter, and is provided with that coil spring of vine volume type to which it can be made to reduce conversely again. the present invention is mechanical by the device expanded for the same part as a blood vessel, a mind official, or it -- it passes and is useful especially because of an in-the-living-body pipeline transplant (transluminal implantatim). With this device of the present invention, the damaged inner wall of a blood vessel or other organs can also be lined by an artificial organization, and this artificial organization can make it porosity. In surgical techniques and other medical technology, For example, it is often required to insert and extend a device to the part which a blood vessel, the urinary tract, or others cannot approach easily, the function of this device is extending the above-mentioned blood vessel or the urinary tract, and this device is left behind to a prescribed position in order to bring about lasting extension if needed. The device by the present invention can be used for many mechanical uses, and can mention use of a different form for an aneurysm brought about by the opposite strangulation which includes expansion of the blood vessel of a certain form, or contraction of a blood vessel as the example. Therefore, if it states specifically, the present invention will support and hold the blood vessel in which the mouth of the venous system opened, It can be used in order to support an artificial blood vessel element, to close the destructive part of a morbid blood vessel, and to Over the destructive part of hypertrophy of a morbid blood vessel, and the inner wall of a blood vessel in a bridge or to stabilize a bronchus pipe or a bronchus. In the present invention, it applies to an inferior vena cava. Therefore, in order to prevent formation of pulmonary embolism, it can design to carry out a duty as a filter for thrombosis. However, the present invention must not be limited to the use mentioned above, but these uses must only be taken into consideration as an example. [Background of the Invention] The device which can be made to expand to a U.S. Pat. No. 3868956 specification after inserting, for example into a blood vessel is indicated. It is based on the operation portion of this device using the metal alloy which has what is called "a memory operation", i.e., the substance which returns to that early form when heated. In this prior art, heating of this substance is performed by electric heating and this device is inserted in an important position. However, ing with the fundamental disadvantageous point that this known art must perform electrical resistance heating in relation to the surrounding sensitive organization, and it may be damaged while this organization heats. When it is indeed said that a patient's blood vessel uses it as a cooling medium when inserting a device in the above-mentioned United States Patent specification (refer to the 3rd column of the 42~48th line) into a blood vessel, but blood is also heated, it is a thermal substance which produces the solidification which is not desirable. [The abstract of an invention] The object of the present invention is to provide the extended device which avoided the defect of known art. It is based on the present invention using the device provided with the coil spring of vine volume type to which it can be made to extend and reduce. The present invention is based on the principle that a small diameter or a larger diameter is given by the spring with a suitable mechanical device. This can be performed by two main different methods included in the frame of the concept of the fundamental invention with same all. Hereinafter, these methods indicate two examples. making it the changes to the small large diameter of a spring from a diameter take place by carrying out relative rotation of the both ends of a spring, and this reducing the number of winding of a spring within the above-mentioned fixed length, and increasing Pitch of a spring according to it, while the 1st method maintains the length of a spring uniformly -- intermediary To have [ from ]. The 2nd method of changing the diameter of a spring is to remove a part of spring material from the spring of predetermined length, and make it change in a smaller diameter take place from a larger diameter in at least 1 end of the spring of predetermined length regardless of Pitch of the spring within the above-mentioned length, and the number of winding. In order to make a spring extend by the method of above others, of course, reverse operation is performed. That is, an additional spring material is supplied to the spring of the above-mentioned length. If this 2nd method of changing the diameter of a spring is desirable, within the above-mentioned length, it can maintain Pitch and the number of winding of a spring, and it can perform it. Of course, the above-mentioned method can be used in order for a smaller diameter to change a coil spring from the state of a larger diameter and to change both into a large diameter from the conversely small diameter again. In one desirable embodiment of the device by the present invention, the larger diameter corresponds to the state where a coil spring is not loaded, sharply. It means that contraction of a spring resists and takes place to the spring resistance, and this happens when the extension removes tension to an unloaded condition on the other hand. While using the 1st method that outlined the spring to the above made to extend and reduce, the end part of a spring can be attached to the shaft arranged in the center inside a spring, and, on the other hand, other ends are connected with the sleeve which surrounds the above-mentioned shaft. The diameter of a spring can be fluctuated by carrying out relative rotation of a shaft and/or the sleeve. In order to be able to remove a coil spring after applying in a certain position, it can connect so that a shaft and a sleeve can be removed for a spring. When using the coil spring of a size small about spring material, in relation to applying a spring in the intended position and making the spring extend, the problem that the support operation of the slippage or the once request of the winding portion of the spring of another material to one side is not obtained may arise. or [ abolishing a possibility that crushing of such a spring may take place ] -- or in order to make it decrease, the guide bar prolonged in the direction of an axis can be arranged on the circumference of a spring. A guide bar is arranged so that it can be displaced on the circumference of a spring, and thereby, spring material is movable to tangential adjusting in relation to extension and reduction of a spring. In one another embodiment by the present invention, it can arrange on the circumference of the spring which supports the guide device which had the support device prolonged in the direction of an axis fixed. Spring material can be moved to tangential adjusting in relation to extension and reduction of a spring via this fixed guide device. In a certain case, it may be desirable to, apply the spring which has large density by between the winding parts of a cotton intermediary spring into the portion to which it was limited of the full length for example, in a hernia or an organization burst. This can be carried out by two different methods in principle. One another method is based on distributing the fixed above-mentioned guide means so that larger winding density than a cotton intermediary may be obtained by the predetermined length of a spring. 2nd another method manufactures a spring in the portion of one piece or some of winding density higher than the beginning -- intermediary To have [ from ]. Of course, the combination of these two another methods can also be used practically. Spring material should be manufactured from a viewpoint with fear of crushing mentioned above in the form by which flattening was carried out, or the form of a band, and it should choose so that the larger size of material may be arranged to the cross section which extends in the direction of an axis. Especially the thing for which a spring is designed to essentially have a rectangular cross section is preferred. In one especially desirable embodiment of the present invention, it has been arranged inside a coil spring, and it had the central part, and the tubular carrier main part of the cylindrical shape is provided with the terminal part in the both ends of the spring which carries out a drive mutually, and the both ends of the spring are connected with each terminal part. This device is provided with the means which can make Mutually carry out relative rotation of the above-mentioned terminal part with that help in order to make a spring extend and reduce further. The means for rotating the above-mentioned terminal part is provided with the coaxial cable connected with the terminal part suitably [ while ], In order to prolong the coaxial element inside the coaxial cable through a carrier main part, to connect the end with the terminal part of another side and to give desired relative motion between terminal parts, the rotation child is stationed in the outside free end section of the coaxial cable. In relation to the embodiment of this latter of the device by the present invention, the terminal part of a carrier main part can make it displaced in the direction of an axis to a central portion, and thereby, between = between a central portion and each terminal part, it can be attached so that the end of a spring can be released. In this case, it is suitable, if the end of at least 1 side of a case is arranged so that it can be displaced in the direction of an axis by the member arranged in the free end section of a coaxial cable. Intermediary To have [ as ] which can achieve optionally the double function of that the member arranged in the free end section of a coaxial cable rotates the 2nd terminal part, and performing displacement of the direction of an axis. Especially it is based on the present invention, in one desirable embodiment, the support member prolonged in the direction of an axis in the circumference of a spring is arranged. A spring is attached to one end of the above-mentioned support member, and the guide member fixed to a part for the end of the another side is provided. In relation to extension and reduction of a spring, spring material can be moved through this guide member. As another mode, the guide means fixed to the end of both support members can be arranged, and spring material can be moved through this guide means. In this embodiment, spring material can be simultaneously sent to both directions in the end of both springs. The long and slender carrier main part in which a spring is arranged [ according to another embodiment ] around as for the device of the present invention, It has the cassette housing arranged at one end of the above-mentioned carrier main part containing the cassette housing of a cylindrical shape, and the sending cylinder with which it was equipped by carrying out eccentricity into the cassette housing, and the circumference portion of the above-mentioned sending cylinder is engaging with the inner side of a cassette housing. It can be made using this device, to move by rotating a sending cylinder in one way or the direction of other, so that a spring may be sent with a cassette housing and it may extend and reduce in those for the nip part between cylinders. In this embodiment, a trapezoid screw can be formed inside a cassette housing and a spring can be slid in this trapezoid screw. It is suitable if friction coating of rubber or a plastic is moreover formed in the external surface of a sending cylinder. In the surgical operation for transplanting a population blood vessel, it is often desirable to establish a porous organization in the inside of a blood vessel from a certain reason. In relation to this, it is possible to provide the stocking of a porous organization the outside or inside a spring by the present invention, and it can transplant the above-mentioned stocking to a desired position with a spring. This stocking can be adjusted according to the diameter of a spring by bending so that it may be based on the elasticity of a porous organization or may suit in a pile. It is a coil spring which is criticality-like [ selection / of the material of the component part included by the device by the present invention / point / this ] first. As this spring material, the metal alloy or the plastic used by being related similarly of the material of medicine receptiveness, for example, non-Stainless steel, and others should be chosen. Probably, the other features and another embodiments will be clear from the claim of the following explanation and the present invention. For example, the still more fundamental advantage of the art of the present invention contrasted with art given in the above-mentioned U.S. Pat. No. 3868956 specification, Good twist operations are possible for the device by the present invention, namely, it can make it extend first after applying a spring. It can be inspected whether before releasing a spring from the member of others of a device after that, the position of a spring and fixation can be admitted by X-rays, and a spring can be released after that, and the residual portion of a device can be removed from an application position. With the device by the United States patent described now, since this possibility cannot make reverse extended operation started in this known art, it is not got at all. [Example] Hereinafter, the embodiment as an example relevant to an accompanying drawing explains the present invention in detail. It should mean, in order that these embodiments may only illustrate the present invention, and it should mind that it is not what restricts the range limited by the claim. The following figure is illustrated to the accompanying drawing. Drawing 1 shows the perspective view of the coil spring for using it for the device by the present invention, Drawing 2 shows the spring in the state where the side view of the coil spring which stored the carrier main part was shown and extended, Drawing 3 shows the spring in the state where the same device as the device shown in Drawing 2 was shown, and it moreover contracted, Drawings 4 thru/or 7 illustrate schematically the principle which removes spring material from the coil spring by the present invention, Drawings 8 and 9 show the transformation embodiment based on the same principle as the principle by Drawings 4 thru/or 7, Drawing 10 shows schematically the possible performance of a coil spring in which the operation of external force was received, Drawing 11 shows the details of the coil spring which uses a guide device, and Drawing 12 expands and shows the device of Drawing 11, Drawing 13 -- Drawing 12 - line -- Judged along -- a detailed section is shown -- the --A [ 13 ] figure shows schematically the spring provided with the support member and the fixed guide member the --B [ 13 ] figure -- the -- the details of the embodiment ofA [ 13 ] figure are shown and Drawing 14 shows schematically the spring provided with the support member and the guide member Drawing 15 shows the details of another guide member, Drawing 16 shows the case where the guide member by Drawing 15 is seen from the upper part, and Drawing 17 shows schematically the whole one embodiment figure of the device of the present invention, Drawing 18 shows another embodiment whole figure of the device by the present invention, and Drawing 19 expands and shows the details of another embodiment of the device of Drawing 18, Drawing 20 shows the side view of the details shown in Drawing 19, and Drawing 21 shows the device by the present invention for applying a porous organization, Drawing 22 shows one embodiment which uses a flat spring material which has a crevice, Drawing 23 shows one embodiment designed as a double ladder-like spring, and one embodiment of the coil which Drawings 24 and 25 adjoin and can overlap a winding portion is shown, Drawing 26 shows the changed completely type embodiment of the spring of this device, and the spring of illustration has a fault operation -- and Drawing 27 -- a spring -- a porous organization -- It is covered -- one another embodiment is shown. In the following explanation, the device by the present invention was used to the blood vessel including a defective position, the blood vessel had a large diameter in comparison in the defective position, and the blood vessel assumes that it has a smaller diameter in the position where this device is introduced into a blood vessel on the other hand. The device according to the present invention with a deer can be used also when avoiding damage to the intravascular wall relevant to insertion of this device for this device to be inserted again into the blood vessel which has a diameter fixed in comparison, and for this move to an application part. Therefore, the device by the present invention is maintainable to a contracted state by a means with a mechanical coil spring of the device, since the above-mentioned contracted state is small smaller than the diameter of the blood vessel in an insertion point, the blood vessel in question is comparatively alike, and has a small diameter -- it can insert easily in an accessible position. The device provided with the coil spring ranks next, and is inserted into a blood vessel, and is moved to a defective position. You are made to extend it mechanically in a defective position until the outside diameter of the spring becomes equal to the diameter of the blood vessel in a defective position or a coil spring becomes large a little rather than it. Subsequently, a coil spring is suitably released from the member of others of the device by the present invention, and in order to achieve the support function from an inner side after removing the remaining portion of a device and, it can leave it to a defective position. If the diameter of the spring in the state where it is not loaded is chosen as a little larger value than the inside diameter of a blood vessel, a spring engages with an intravascular wall with a certain specific pressure, and fixes a blood vessel. The size of this specific pressure can be calculated beforehand, therefore can be chosen as a request. The diameter of the coil spring of the screw type by one embodiment of the present invention changes to Drawings 1, 2, and 3 of an accompanying drawing how in principle, and salted entrails and roe of the ayu, or sweetfish are shown in them. Drawing 1 shows schematically the coil spring which has axis 2 of the longitudinal direction shown schematically. Numerals 3 and 4 are given to the both ends of the spring. The coil spring of Drawing 1 shows the shape at the time of the state where the operation of external force is not received (it is called henceforth "a pause position"). If both ends 3 and 4 of a spring are made to rotate in the direction of arrows 5 and 6 by the operation of external force by the surroundings of axis 2 of a longitudinal direction, while the diameter of a spring decreases, the number of winding of a spring increases according to it. Coil spring 1 in a pause position is shown in Drawing 2 with the side view. In Drawing 3, the state after diameter reduction has shown the same spring 1 by explanation about Drawing 1. spring 1 -- the -- 3 times of the number [ in / diameter d3 can be given in the position of 3 figure, and diameter d3 is 1/3 of diameter d2 of Drawing 2, and / in the number of winding of a spring / a pause position ] of winding -- intermediary To have. Since length L of a spring is not changing, Pitch s3 of the coil spring in the position by Drawing 3 is 1/3 of Pitch s2 of the pause position by Drawing 2. Central body 7 of the cylindrical shape which has a function which stabilizes spring 1 in the state by Drawing 3 where it contracted is shown in Drawings 2 and 3 by the dash line. The principle of another embodiment by the present invention is shown in Drawings 4 thru/or 7. Intermediary To have [ as ] which according to this embodiment happens without the diameter of a coil spring changing Pitch of the spring. Coil spring 1 in the pause position by Drawing 4 has diameter b4, length L4, and Pitch s4. Although Drawing 5 has shown the same spring, it has diameter d5 which decreased in the abbreviation half of diameter d4 by Drawing 4. However, in this state, the spring has two portions A and B of different Pitch. Portion A has the length and Pitch as length L4 and Pitch s4 which it has in a pause position with same spring, and, on the other hand, portion B has Pitch s5 quite smaller than length L5 and s4 quite smaller than L4. Reduction of the diameter from the pause position by Drawing 4 to the state by Drawing 5 is obtained by rotating the both ends of a spring in the same mode as having been shown in Drawings 1 thru/or 3. Thus, a Good mechanical mean [ dividing the contracted spring into two fields of different Pitch ] can perform. It is the same spring 1 as Drawing 4, and spring 1 which has diameter d6 which moreover decreased in the abbreviation half of diameter d4 is shown in Drawing 6. This spring has two portions C and D. Portion C has the length and Pitch as length L4 and Pitch which it has in the pause position with same spring. In portion D, spring 1 forms the spring of a concentric flat screw type. Drawing 6 has shown the end elevation of the screw type spring to Drawing 7, and the appearance of portion D is clear from this figure. Therefore, in this embodiment, full length L4 and Pitch s4 of a spring are the same as the full length and Pitch in the pause position of a spring. Suitable mechanical contrivance can perform change from the pause position of spring 1 to the state by Drawings 6 and 7. In order to make a surgical operation possible, for example, it has been shown in Drawings 1 thru/or 7 whether the diameter of the coil spring of the screw type by the present invention is changeable into the appearance like The squid. Hereinafter, a different practical solution which exists in order to enable extension and reduction of a coil spring as a request is indicated. It is possible that portion B of the embodiment by Drawing 5 is a storing portion of the coil spring material which supplies portion A of spring material in the state of extension again. The side view and end elevation of the device to which the principle described now is applied are shown in Drawings 8 and 9, respectively. In storing portion B, the winding portion of a screw type is close to Mutually, and is arranged. Drawings 8 and 9 show schematically the mode controlled to perform sending through Nip formed among small sending rollers 15 and 16 which rotate to two opposite directions, and to send the material of a screw type in the direction of arrow 18 gradually by that cause, and to be sent out at the end 17 of Nip of a roller. Drawings 8 and 9 show portion A of the coil spring after extending to a pause position. Of course about application of the coil spring by the device by the present invention, it is also possible to change as required [ in the length of a spring ] by the operation from the outside, in order to make it adapted for a different situation after application. therefore, this spring can be compressed in the direction of an axis before extension, during extension, and after extension, and can be made to extend in the direction of a until axis even to an extended state exceeding the state where after that, for example, neutrality, is not loaded by that cause, and a neutral state In the case of this latter, a spring can be further stabilized more than it from a viewpoint of the tension stored in the spring. When applying the art by the present invention to the surgical operation of a human body, it is suitable if the diameter of the coil spring in the state where it contracted or decreased is kept from being larger than 8 mm thru/or 10 mm. The diameter of the spring in an extended state can be made into the range of 12 mm thru/or 30 mm. For example, about the coil spring manufactured by the line of non-Stainless steel which has about 0.3-mm thickness, extension from 8 mm to 12 mm of extension, i.e., 50% of the degree, and the number of extension of 1.5 (12/8=1.5) are obtained, for example. It became clear by using this charge of a wire rod that it was impossible to manufacture the coil spring which has a diameter of about 30 mm in an extended state in a pause position. It became clear that there was a relation which is between the thickness of material and the number of extension about all the spring materials which are related by investigation. Although this relation is influenced by material, the charge of a wire rod which should be chosen becomes thin, so that the number of extension for which it asked is generally high. Since a pause position 30 mm in diameter is used from a contracted state 8 mm in diameter as an example (i.e., in order to obtain 3.8 extension), it can be said that the steel band of the charge of non-rust steel materials which has a width of 1 mm and a thickness of about 0.15 mm is required. Completely generally a line or the suitable interval about the thickness of a band is about 0.08 mm thru/or 0.30 mm. Intervals suitable about the width of band material are about 0.3 mm thru/or 2 mm. A paraphrase means that this must use a line or a thin material of the form of a band in order to use the art by the present invention for the object of a surgical operation and to manufacture a coil spring in large Low. However, the coil spring based on this material supports a blood vessel satisfactorily enough, when applied to a defective blood vessel. It became clear that it had the tendency for the coil spring manufactured with a thin material to become unstable mechanically in the state of extension in fact. Therefore, for this reason, an inclination and crushing of a spring are caused after application. The mode in the extended state after coil spring 1 manufactured with a thin material applying which arises more unstably is schematically shown in Drawing 10. The dash line shows the wall of the blood vessel which the spring extended to the inside. Such instability of a coil spring is not often permitted. This is because the operation which restricts the flow of blood rather without being able to achieve the meant function to remove the defect of the above [ a coil spring ] is carried out. In the present invention, a possibility of producing crushing of this spring forms a fixing device which acts on the coil spring in both a contracted state and an extended state at a coil spring. or [ therefore, / that it can lose ] -- again -- a pigeon -- also writing -- it can essentially prevent. Drawings 11, 12, and 13 have illustrated one embodiment of the device by the present invention provided with this fixing device. Drawing 11 shows a contracted state with numerals 21, and shows schematically the portion of the coil spring in which the extended state was shown by 21a. This figure has shown three guide members 22 for a coil spring. moreover in mutual distance s12, common flexibility boils guide member 22 comparatively, and it is arranged on rigid line 23 so that clearly from Drawing 11. Drawing 12 expands and shows the details of the device of Drawing 11, and Drawing 13 shows the Judged along section to - line for Drawing 12. Coil spring 21 was prolonged through the hole, i.e., opening 24, of guide member 22, and, on the other hand, line (thread) 23 is prolonged through hole 25 of guide member 22 so that clearly from Drawings 12 and 13. About the embodiment illustrated to Drawings 5 and 6, if it constitutes so that it may fix to line 23 and guide member 23 may be attached, it is suitable. Thus, Pitch s12 was maintained in the contracted state and the extended state, and all have agreed in the explanation about Drawings 5 and 6 mentioned above. the --A [ 13 ] figure shows one embodiment of a coil spring with a stable guide member fixed in the extended state. In the end 21a, it fixes to the direction support member 23a of an axis, and coil spring 21 suitably manufactured in thin metal bands is attached. one flexible band in which support member 23a was attached mutually suitably, or two flexible bands -- intermediary To have [ from ]. End 21b of another side of coil spring 21 is connected with support member 23a by fixed single guide member 22a of the form of the loop which has a rectangular opening. When it was fully stable for practical use of spring 21 in this embodiment, the end of spring 21 was stabilized by support member 23a and it was connected mutually, it came out enough and, also unexpectedly, a certain thing became clear. intermediary To have for the advantage of this embodiment provided with the single guide member in which extension and reduction of a spring are easy since through tells a single guide member that a spring may carry out -- they are things. the --B [ 13 ] figure expands and shows the suitable design of the joining segment to guide member 22a and its support member 23a. Guide member 22a is formed using the band which has a loop-like projection part, and this band forms rectangular crevice 22a with support member 23a. You can make it slid [ easily ] spring band 21 in the above-mentioned crevice 22a simultaneously stabilized. moreover -- as another mode -- the -- the [A / 13 / figure and ] -- the embodiment indicated at the last called atB [ 13 ] figure can be changed by arranging a fixed guide member at each end of support member 23a. Thus, although it can be fed into the both ends of spring 21 or can be sent out from these both ends, this is advantageous [ spring band material ] in the large number of extension, when a longer spring band material of length must be simultaneously stored in the both ends of a spring in relation to contraction of a spring again. About this embodiment, a spring can be more nearly satisfactorily stabilized in intermediary If you go in which the distance between fixing points 21a and 22a is longer than the usual length of the spring in the state where neutrality is not loaded, and an extended state. However, in the embodiment by Drawings 2 and 3, it can change according to the matter which has been arranged so that guide member 22 can be displaced on line 23, and mentioned Pitch of the coil spring above by that cause. Drawing 14 shows schematically the side view of the coil spring you were made to be stabilized in the pause position which was carried out in this way and extended. The material of a coil spring is a form of a line (thread) or a band suitably, namely, the material of the coil spring mentioned above circular or having the shape by which flattening was carried out on the direction cross section of an axis. The coil spring manufactured with the material of the shape of a band was more stable, and it became clear that there were few tendencies which incline or are crushed. However, it should be made for the width of a band not to exceed 1 mm thru/or 1.5 mm from a medical reason generally. Since growth of an organization will be barred and specific engagement pressure power will become lower as a result if this width is enlarged further, a fixed state falls. Since better fixation indispensable to application of the spring to the inside of the blood vessel from which displacement of the direction of an axis of the spring which this applied by the pulse rhythm is obtained is obtained, it is preferred to make specific engagement pressure power high. One method of improving the fixed state of a spring is making the external surface of spring material coarse for example, according to injection finish. The projection part prolonged in the method of outside by Push omission again can be formed in spring material, or it is as another mode, The growth of an organization in the field to which it could punch by depending band material for example, without Push, or using laser, and thereby more good fixation was obtained, and the spring was applied becomes easy. Drawing 15 expands and shows one embodiment of the guide member which gives the stability of a good spring also in the large number of extension. Guide member 27 is provided with crevice 28 of the rectangle for guiding coil spring 29 of the shape of a band, as the cross section showed. If the size of crevice 28 is chosen so that coil spring member 29 can slide easily through the crevice when a spring is made to extend and contract, it is preferred. Simultaneously, inclination of a coil spring is prevented and, thereby, inclination power is absorbed by the line combined with the guide member arranged in a guide member and hole 25. Drawing 16 shows corresponding guide member 30 seen from the upper part. Dash line 31 shows the crevice which has a rectangular cross section, and dash line 32 is equivalent to hole 25 of Drawing 15. Chuo Line 33 and 34 crosses mutually at an angle different 90 degrees so that clearly from this figure. Thereby, a guide member can be adjusted to the pitch angle of a coil spring about a line, and a motion of a coil spring when changing the diameter of a spring in this mode becomes easy. Drawing 17 shows one embodiment of the device according the form of instrument 35 for performing a surgical operation to the present invention. Coil spring 36 is arranged around carrier main part 37 of a cylindrical shape in the state where it contracted. This carrier main part 37 is provided with tubular central portion 47 and terminal parts 40 and 41. Relative rotation can be made to be able to carry out mutually with rotation ring 45, and terminal parts 40 and 41 can be displaced in the direction of an axis to central portion 47 again. In the end part of carrier main part 37, terminal part 41i connection of one side is done for flexible coaxial cable 42. This coaxial cable 42 is provided with outside tubular portion 42b and inside element 42a. Inner side element 42a is prolonged through all the portions which result in the 2nd terminal part 40 through terminal part 41 and central portion 47 of carrier main part 37, and is firmly attached to the 2nd terminal part 40. Head members 43 and 44 are arranged in a free end section of coaxial cable 42. One head member 43 of them is connected with lateral part 42b of coaxial cable 42, and, on the other hand, head member 44 of another side is connected with inner side element 42a of coaxial cable 42. One end 38 of coil spring 36 can Pincer terminal part 40 by being displaced in the direction of an axis in slit 46 formed between central portion 47 of carrier main part 37, and terminal part 40. End 39 of another side of coil spring 36 can Pincer terminal part 41 by being displaced in the direction of an axis similarly in slit 48 formed between terminal part 41 and rotation ring 45. Displacement of the direction of an axis of inner side element 49 of coaxial cable 42 by operation of head member 44 can perform release from Pincer of ends 38 and 39 of coil spring 36 in the inside of each of slits 46 and 48, and slits 46 and 48 of the ends 38 and 39. It is operated so that a head member may also produce displacement of the direction of an axis. It can carry out, when mutual relative rotation of ends 38 and 39 of both coil springs 36 makes the relative rotation of the head members 43 and 44 carry out mutually by the principle which Drawings 1 thru/or 3 illustrated. Central penetration passage 49 is formed in the instrument shown in Drawing 17. The instrument of others for contrast liquid and a medical survey can be poured in and inserted into a blood vessel by passage 49. When the function of the illustrated device is described briefly, it is as follows. Carrier main part 37 provided with coil spring 36 attached to each slit 46 and 48 is inserted in the position which the blood vessel in question can approach easily, and it is quickly inserted in the defective position which has a larger diameter in the state shown in Drawing 17, i.e., the state where coil spring 36 contracted. Extension of coil spring 36 is obtained by carrying out relative rotation of the head members 43 and 44 mutually. After coil spring 36 is extended to the state where tension does not act, or the state where tension does not act substantially, the ends 38 and 39 are released by displacing head members 43 and 44 in the direction of an axis mutually, and extending slits 46 and 48. Thus, support main part 37 which both ends 38 and 39 of coil spring 36 were released, and was attached to coaxial cable 42 and the cable after that can be removed from a blood vessel. In order [ whole ] to carry out a surgical operation, another embodiment of the device by the present invention of the form of the instrument shown with numerals 51 is shown in Drawing 18. this device is based on the principle of the spring shown in Drawing 5 -- the [ and ] -- the [A / 13 / figure and ] -- it relates to the embodiment shown inB [ 13 ] figure. In Drawing 18, after spring 52 has contracted, it is shown. Intermediary To have [ as ] to which support means 53 prolonged in the direction of an axis of spring 52 is firmly attached to end part 54 of the spring, and can move the end of spring 52 through guide member 55 arranged at support member 53 on the other hand. Spring 52 and support member 53 are attached to elastic hollow main part 56 of a cylindrical shape by Latchch which it provided at a time in each one end of the support means 53 and which is not illustrated. Each can release the inside of coaxial cable 57 connected with hollow main part 56 and the main part from the both ends of support member 53 with the prolonged wire, therefore these Latchch can carry out it in this way, and it can control them from the outside. between coaxial cable 57 and end 55 of support member 53, as a spring shows the surroundings of carrier main part 56 with numerals 58, it is comparatively alike, and it is close and is twisted. End 62 contiguous to coaxial cable 57 of spring 52 is connected so that it can release to sleeve 59. Carrier main part 56 of a cylindrical shape can be surrounded, it can be made to be able to rotate with the flexible tube arranged in same mind in coaxial cable 57, and sleeve 59 can be moved in the direction of an axis. Extension of spring 52 is performed by rotating sleeve 59, and the excessive portion of the spring adjoined and stored in sleeve 59 is extended simultaneously with spring 52 which moves through guide device 55. Sleeve 59 is made to move ahead gradually during extension of spring 52 by movement of the direction of an axis of a flexible tube. The full length of spring 52 is beforehand adjusted so that only the spring material of short length may be arranged on the outside of guide member 55, when extension of the spring is intercepted with the wall in surrounding of a blood vessel. When a surgeon checks that spring 52 is arranged in the right position, spring 52 is released by releasing the above-mentioned Latchch and the attachment portion of end 60 with carrier member 53. If it becomes clear that it is required to be unsuitable and to exchange by the length of the selected spring about application of this instrument, before this change releases Latchch and end 60 by rotating sleeve 59 in the opposite direction, it can be carried out by contracting spring 52. Thereby, an instrument can be removed and spring 52 can be replaced with another spring which has suitable full length. According to another embodiment of the present invention, excessive portion 58 of the spring twisted around the outside of hollow main part 56 by being close can be stored in a sleeve, and can be sent out from the above-mentioned sleeve through guide member 55 (Drawing 18) by a suitable member. This embodiment is shown in Drawings 19 and 20 in the direction section of an axis, and the radial section, respectively. According to this embodiment, in cylindrical shape housing 61, sending cylinder 63 carries out eccentricity and it is equipped with it. In housing 61, cam 66 is cut and trapezoid inner side screw 67 is formed. The outside of sending cylinder 63 is covered with rubber layer 64. When using this device, band material 72 of a coil spring is arranged inside trapezoid screw 67, and rubber layer 64 provided on sending cylinder 63 carries out pressurization engagement to Along band material 72 at distance 68~69 (Drawing 20). Now, if sending cylinder 63 makes it rotate in the direction of arrow 71, spring band 72 is made to move forward through guide member 55 (Drawing 18), and a spring is extended simultaneously with it. From a viewpoint to which sending cylinder 63 which has rubber layer 64 engages with the full length of trapezoid screw 67 with the inner side of a Along this trapezoid screw, if sending cylinder 63 is rotated in the opposite direction, spring band 72 can be drawn in back and a coil spring contracts. The advantage which stores the excessive portion of spring material in a casing with Drawings 19 and 20 is important. Therefore, the excessive portion of a spring disturbs extension of a coil spring, and the organization around reduction from a viewpoint surrounded in the casing, or it does not stimulate. the sending mechanism of the spring which moreover lets terminal guide member 55 (Drawing 18) pass, and guidance -- the full length of a spring -- Along -- it is very uniform and the controlled extension is obtained. The fact of this latter means that the transplant of a spring becomes quite easy. in a certain case, be alike -- for example, the inner wall of a blood vessel or other organs damaged in order to prevent destruction of a blood vessel -- for example, lining by porous artificial tissue may be desirable. Such all the linings can be given using the device by the present invention. the [ in the contracted state which Drawing 21 equipped with support member 23A ] -- the cross section of spring 21 called atA [ 13 ] figure is shown schematically. The porous organization of the form of stocking 73 of a cylindrical shape is stationed around spring 21, and it is attached to carrier member 23A by thin line 24. This organization 73 is bent so that it may overlap in bending positions 75 and 76, and it surrounds spring 21 of a contracted state closely. Stocking 73 is held by thin metal wire 77 prolonged in the direction of an axis arranged in bending position 75 in this position. After being inserted in a damaged area with the instrument by Drawing 17, metal wire 77 is removed and, thereby, spring 21 is made to extend with stocking 73 in which spring 21 surrounds it. While spring 21 is extended, stocking 73 is opened completely and you are made to be engaged closely eventually to the inner side of the damaged area of a blood vessel. Of course as an alternative plan of the embodiment mentioned above, the stocking of a cylindrical shape can be manufactured with elastic material. An extended state can be made to extend this elastic material without bending the material doubly in relation to extension of a spring. As such a material, the thing of the form of tricot round, for example for which sewing was carried out or the article of the round fine mesh which Braid(ed) is used can be performed, for example. in order to avoid damage to inside the blood vessel relevant to insertion of the instrument to the inside of a blood vessel moreover by the case where the instrument whose embodiment as such an alternative plan is natural for example, which has a spring in a contracted state was comparatively alike, and is inserted into the blood vessel of a fixed diameter Especially in the small number of extension, it is useful by a case so that a certain amount of contraction may be required to the inside diameter of a blood vessel. It is not limited to the embodiment which the present invention mentioned above, and he should understand having intention of the above-mentioned embodiment only illustrating the present invention. Therefore, the housing shown in Drawings 19 and 20 can store the arbitrary suitable sending devices which can move a spring within and without casing 61 instead of sending cylinder 63 by which eccentric wearing was carried out. The sending roller which is made to rotate so that it may return into housing 61 before being moved in the direction of an axis in relation to storing of a spring as an alternative plan considered and removing an instrument from the after-completion application site of sending of a spring and which is arranged concentrically, or a sending screw can be mentioned. the [ which uses the guide member moreover fixed to each end of a spring in the both ends of a spring for simultaneous sending ] -- the [A / 13 / figure and ] -- in order that the position of the middle of a spring may support member 23A, the embodiment which indicatedB [ 13 ] figure can be designed so that it may be stopped firmly. In the embodiment shown in Drawing 22, the spring comprises material 78 of the band form provided with long and slender opening 79. Opening 79 is formed for example, of Push omission. Thus, a spring is formed in the shape of a ladder. The spring of Drawing 1 and spring 78 which can be made to extend similarly showed very good stability, and has abolished a possibility that the inclination of the spring in the mode shown in Drawing 10 may take place. By choosing suitably the thickness of a band, and the width of the remaining portion with a stair-like band, good stability and the high extendibility from a small diameter to a large diameter are combinable. By another modes other than Push omission of an opening, the spring shown in Drawing 22 and the spring which has the same good stability can be manufactured. Therefore, the spring of the ladder form manufactured from the round wire instead of the flat band is shown in Drawing 23. In this case, a spring is manufactured by forming a ladder form portion first by attaching two adjoining parallel wires 80 and 81 with transverse direction element 82. It can also be considered that this device is a double spring which consists of two springs 80 and 81 of a single object again. As mentioned above, it is necessary to line the wall part of the often damaged organ in a certain organization. In Drawing 23, the device introduced into the organ which injured such an organization is shown. Although this device is illustrated about the specific spring shown in Drawing 23, it should care about that this device can apply to the coil spring of all the form, of course. The spring of Drawing 23 is surrounded with stocking 95 of a certain porous material. It is taken and made the stick or rigid wire 94 prolonged in a longitudinal direction by the stitch etc. which were shown with numerals 97, and stocking 95 is Being done. Wire 94 ranks next, for example, is attached to springs 80 and 81 at crossing 96 in a suitable mode by a means similar to the adhesion or it by spot welding and glue. Since the duty as a graft in the transplant in a blood vessel could be carried out and the spring fixed stocking 95 to wire 94 prolonged in the direction of an axis by this composition, Since stocking 95 is fixed to the total prescribed position in an application operation period, after applying to the inside of a blood vessel, the stocking 95 whole surrounds springs 80 and 81, and forms artificial tissue into a blood vessel. If it is manufactured from a porous material of a certain elasticity which can follow spring material when a spring extends stocking 95 in relation to application in the intended position, it is preferred. Therefore, stocking 95 can consist of arbitrary materials of tricot form of having necessary elasticity knit or sutured, or crepe products of a certain form. The material replaced with this is an elastic plastic film, i.e., the elastic body of silicone resin. The embodiment shown in Drawings 22 and 23 can be used as a carrier for the organization which illustrated into a porous material, for example, Drawing 24, as what is replaced with the embodiment described now. For example, ladder form spring 83 designed like the spring of Drawings 22 or 23 is covered with porous material 84. However, in order to obtain the density for which it asked between the winding portions of a spring, the double support spring is changed a little in that the transverse direction step of the ladder equivalent to element 82 of Drawing 23 is constituted by step 85. Thus, the winding portion of a spring overlaps mutually and it can obtain the density of Fitted together and a request. Drawing 25 expands and shows the direction cross section of an axis of two winding portions of the spring of Drawing 24 which adjoined. Horizontal element 82 is provided with shoulder 86 so that I may be understood from Drawing 25. This spring is covered in porous organization 84. A seal will be obtained, even if a spring moves in the direction of an axis so that clearly from Drawings 24 and 25. If it is desirable to use the device by Drawing 17 in order to make a spring extend as for this, it is important. Since the distance between members 38 and 39 is constant, Pitch of a spring is changed when these members 38 and 39 carry out relative rotation mutually. By using Drawing 24 and the 25th embodiment, while maintaining a seal from a viewpoint to which transverse direction element 82 slides in the direction of an axis mutually, change of Pitch by rotation of members 38 and 39 is attained. For example, when a spring is attached for the device by Drawing 17 and is in a contracted state, piling of the winding portion of a spring is large in comparison, and the spring by Drawing 24 can be designed so that piling of the after-extension winding portion of a spring may become small in comparison on the other hand. Supposing to maintain the same Pitch in the contracted state and extended state of a spring by Drawing 24 and Drawing 25 is wished, This can be performed by changing the device of Drawing 17 so that members 38 and 39 may approach mutually, or may separate mutually and may move in the direction of an axis, when a spring is extended and contracted. Thus, Pitch can be uniformly maintained in comparison and this is especially important about the embodiment of Drawings 22 thru/or 25. In a certain case, it is suitable, if it designs in the form of the semipermeability portion of band-like material rather rather than attaching a porous organization to the outside of the device of a ladder form. Therefore, a very fine hole is formed so that the same punching side may be acquired, when opening 79 of Drawing 22 can be replaced with the band material main part formed thinly in this case and it forms thinly. Fixation which needs horizontal element 78 is performed in this case. One more advantage of the device by Drawing 24 is necessarily not having elasticity, in order that a porous material may participate in extension of a spring. Drawing 26 shows transformation of the design of the device by the present invention. The transformation spring which shows the whole in Drawing 26 shown with numerals 90 is designed as a spring of the common use which has a diameter of cotton intermediary regularity to the greater part of the length, and, on the other hand, it is designed to have the diameter which decreased in the upper end part 91, therefore spring 90 has the form shown in Drawing 26 in the state where it is not loaded. In order to give explanation of the function of the following springs easy, numerals 92 show the free end section below spring 90, and, on the other hand, numerals 93 have shown the free end section of the upper part. About contraction or extension of the spring at the time of applying to the position which meant spring 90, the function of the spring shown in Drawing 26 is the same as that of the spring of the embodiment mentioned above. However, a certain amount of change of the instrument which should be used in view of the fact that spring 90 is provided with diameter reduction end 91 in order to operate a spring may be desirable. For example, The instrument shown in Drawing 17 can remove terminal part 40, and by providing the slot of the transverse direction meant so that upper part free end section 93 of spring 90 might be stored and held to inner side element 42a of the end which extends through carrier main part 37, it can change it so that it may be adapted for the spring by Drawing 26. Subsequently, end 92 of another side of spring 90 can be held at the end of another side of carrier main part 37 connected with terminal part 41 in the same mode as the mode which indicated Drawing 17, Spring 90 can be shrunk by making the relative rotation of the rotating members 43 and 44 carry out mutually in the mode mentioned above after that. When spring 90 is in a contracted state, it can apply to an inferior vena cava in the position of the request of spring 90 inside a blood vessel for the object of preventing pulmonary embolism, for example. As for the filter device known [ from ] before meaning so that it may be applied to the inside of a blood vessel for the object of catching a thrombus, this device is a means of a point, Hook or it, and a class. ing which is everlastingly attached into a blood vessel and has the disadvantageous point that correction of a position and removal of a filter are impossible, by that cause. An example of this device is written in the U.S. Pat. No. 3540431 specification. However, an essential advantage is acquired while these defects are avoidable by using the device by the present invention which is illustrated in Drawing 23. The following matter is included in this essential advantage. 1 It is automatically attached by carrying out engaging of clutch so that the spring which has a fault function may not damage this inner wall in the inner wall of a blood vessel. 2 The position of a spring can be corrected and it is possible to remove a spring. 3 This device does not carry out small deer reduction of the flow of that blood through the section of a blood vessel. 4 Application within the blood vessel of a device is quite easier than application of the device of a prior art. In order to prevent the blockade of diameter reduction end 91 of spring 90 by the small lump of the solidified blood, the distance between the winding portions of the spring of the diameter reduction portion of a spring is about 3 mm. By using such a distance, passage of a larger thrombus is avoided and the premature blockade of one diameter reduction end is avoided. The spring inserted and applied, for example into the blood vessel about the embodiment of Drawing 26 and the embodiment of others of the spring of the device of the present invention can be removed in the following mode. The flexible tube of the diameter adjusted according to the blood vessel is further inserted to end 93 of the another side to end 92 of spring 90, After that, the end of a spring is grasped by the suitable position by a gripping member, and as a result, it can draw in a spring so that the surrounding organization may not be injured through a tube. This technique can be conveniently used, when the position whose spring is not right in a blood vessel is occupied or it arrives at the position which is not right. Drawing 27 shows the transformation embodiment of the device by Drawings 24 or 25 which can line the inner wall of the damaged organ in a porous organization. This embodiment is provided with the spring of the form illustrated to Drawings 22 and 23, and the numerals of this figure are the same as the numerals used for Drawing 23. It is It is covered by stocking 83 of the porous organization where double spring 80~82 surrounds the separate winding portion of a Along spring for the full length of a spring according to Drawing 27. As for stocking 83, the inner side of the contiguity winding portion of a spring overlaps so that clearly [ it may extend sideways on the outside of a spring and ] from Drawing 27 by that cause. A seal will be obtained, if the device by Drawing 17 is used in order to move a spring in the direction of an axis, for example, to make a spring extend in this case. About other points, the device by the present invention includes the following feature by independent or arbitrary combination. (a) The state (Drawing 2, Drawing 4) of above others has agreed substantially in the state where coil springs 1 and 36 are not loaded. (b) Shaft 42a and sleeve 42b should be connected with coil spring 36 so that release is possible. (c) Guide bar 23 prolonged in the direction of an axis is arranged around a spring, it is arranged so that at least one guide member can be displaced on guide bar 23, and spring material can be moved to tangential adjusting in relation to contraction or extension of a spring through guide bar 23. (d) Cotton intermediary distribution of the fixed guide member 22 should be carried out at the above-mentioned predetermined length of a spring, be arranged around the spring on support member 23 prolonged in the direction of an axis, and spring material 21 should move to tangential adjusting through the above-mentioned fixed guide member in relation to extension of a spring, or contraction. (e) It can attach so that carrier's 37 terminal part or its portions 40 and 41 can be displaced in the direction of an axis to central portion 47 and ends 38 and 39 of a spring can be released by that cause in between [ 46 and 48 ] = between central portion 47 and each terminal part 40 and 41. (f) Displacement in the direction of an axis be possible by member 44 by which the portion of at least 1 side of terminal parts 40 and 41 is arranged in the free end section of coaxial cable 42. (g) Support member 23a prolonged in the direction of an axis is prolonged around spring 21, intermediary To have [ as ] which end part 21a of spring 21 is attached to support member 23a, and fixed guide member 22a is provided in end 21b of another side of spring 21, and spring material can move in relation to contraction or extension of spring 21 through fixed guide member 22a -- things. (h) intermediary To have [ as ] which the support member prolonged in the direction of an axis is arranged around a spring, a fixed guide device is arranged to the both ends of the support member, and the material of a spring can move in relation to extension and reduction of a spring through the above-mentioned fixed guide device -- things. (i) Spring 52 is arranged around long and slender carrier main part 56, The cassette magazine which equipped one end of carrier main part 56 with sending member 63 arranged so that it may rotate in cylindrical shape cassette housing 61 and cassette housing 61 is arranged, It can move in order to make a spring expand and contract by rotating sending member 63 in one way or other directions. (j) sending cylinder 63 in which the sending member carried out eccentricity and it was equipped with it into cassette housing 61, cylinder 63 to which a circumference portion engages with the inner portion of cassette housing 61, and intermediary To have [ from ] -- things. (k) The trapezoid screw should be formed inside cassette housing 61 on which spring 52 can slide inside. (l) Sending cylinder 63 should equip the outside with friction coating 64 of rubber or a plastic. (m) Spring 52 is arranged around long and slender carrier main part 56, And the end part of a spring is attached and the end part of carrier main part 56 extends from the end of another side of the carrier main part surrounded with the spring in which magazine portion 58 supports rotation sleeve 59 to an outside end, Form the device for it being attached to the end of another side of rotation sleeve 59 so that a spring can release, and rotating rotation sleeve 59 to carrier main part 56, and making it displaced in the direction of an axis. (n) Stocking 73 can be adapted for the diameter of the spring relevant to extension of a spring by the elasticity of a porous organization. (o) Can be adapted for the diameter of the spring relevant to extension of a spring by bending portions 75 and 76 which stocking 73 overlaps. (p) When stocking 73 sews with thread, be attached to spring 21. The vine volume spring of a conventional form is in the term which it "coil spring" Comes to set to the indication of the present invention very. however, it is used for the device of the present invention -- also Be sure to(ing) -- it is not necessary to have a fixed diameter or fixed Pitch However, general shape is the shape of vine winding. The present invention is useful again also to a certain kidney disease to which what is called hemodialysis is performed. In this operation, a needle or cannula is applied to a patient's arm, and thereby, a patient's blood is extracted from the body and returned to an after-dialysis patient's body in a dialysis device. Since hemodialysis must be repeatedly performed once in at least one week, a problem arises about a patient's blood vessel. This problem is solvable by forming what is called a bypass that constitutes a lasting joining segment between the artery of a patient's arm, and a vein, if it falls ill. A I got it. vein can constitute this joining segment from the calf which is what is called an artificial blood vessel (prosthesis) or "Sorco graft (solkograft)." The advantage which uses this bypass is that a connection vein extends a connection artery and the high blood pressure from an artery makes approach possible easily at the time of insertion of cannula. Many dialysis can be performed before exchanging joining segments moreover. A connection lead pipe is usually arranged at hypodermic, and is attached to an artery and a vein by suture. However, the joining segment used conventionally has started a certain problem. When an artificial blood vessel is extracted from hypodermic during operation, the artificial blood vessel can be bent and it can blockade. After the cannula for hemodialysis is removed, a connection artificial blood vessel must be compressed and the loss of a lot of blood must be prevented. An artificial vein can be crushed easily and it can avoid checking circulation of subsequent blood then. When a joining segment was attached to a vein, it became clear that what is called strangulation took place. Now, it became clear that the disadvantageous point concerning the above-mentioned connection lead pipe or an artificial blood vessel could be abolished by using the device of the present invention by the following method. The coil spring which has a suitable diameter and the suitable number of winding is attached to the instrument by the present invention which was illustrated to Drawing 17. It is in the state where the spring contracted, in Drawing 17. For example, the end part of an artificial blood vessel like a Sorco graft is attached to a patient's vein by several stitches. Subsequently, it arrives at about 2-cm position inside a vein with the end where the device by the present invention containing a spring was inserted into the graft, and the spring corresponded [ the outside end of the device ] by that cause. Subsequently, it is made for a spring to be extended by the inner side of an artificial blood vessel, and is released from an instrument. Then, an instrument is removed from an artificial blood vessel. The free end section of a graft is sent to the opening of an artery by hypodermic cut, and is attached to an artery. It became clear that the above-mentioned device had a large advantage. 1 When a graft is transplanted, don't be crushed for an operation of a spring. 2 In order for a connection lead pipe, i.e., an artificial blood vessel, to reduce the loss of blood, compress it safely after removal of cannula, or bind it tight, and this lead pipe should return to that diameter of the maximum immediately by operation of a spring. 3 It is easy to find a hypodermic artificial blood vessel, and, for this reason, the hole dawn of a lead pipe is easy. 4 It became clear that a possibility that strangulation may be formed in a vein decreased. Since strangulation arises in using conventional art, a connection part must be changed once per year at least, and it must move to another position. In addition to application of the present invention which was mentioned above, there is an important field of others which can use the device of the present invention. It is difficult to do the examination on an animal, for example, a dog, now, and it is desirable to pour in a medicine several times on the 1st, in order to study the effect of a prolonged examination in that case. Since operation tended to have caused strangulation quickly above all, this experiment was not able to be performed to today.
