Remote fiber optic medical procedure and device.

[Detailed Description of the Invention]

The present invention is generally seen among them, relates to a useful medical device in a detecting method and such a method, in order to observe the operation end of a catheter distantly especially, while the textiles bunch for optical transmission of a byway is used, is seen, and relates to a detecting method. The car between stocks is unmolded. When seeing among them and performing a detecting method, it is necessary to Insertion the operation end of an endoscope in the bodily tissue which detects appropriately, and to perform a desired medical inspection in it. Therefore, it is required to be able to use a certain means to enable it to guide the portion of the body which observes the above-mentioned action part and needs a medical measure. Usually, the endoscope penetrated the channel of the body and arranges the textiles bunch for optical transmission. Some textiles transmit light to Cavity in the living body. A doctor observes the inside of the body with the return light (namely, configuration light) which passes along the magnifying device of a certain kind which is the expansion lens which suited in many cases. Thus, the Medical doctor can carry out direct observation of the collected image. Thus, when the textiles bunch for optical transmission is inserted in an endoscope, some inconvenience arises. Since a view is restrained by the inner side shape of the passage along which the left end of an endoscope passes, positioning of an endoscope is spoiled. In that case, since the operation end of an endoscope comes to the back of the view from the textiles bunch for optical transmission, or the side, the first fault is being unable to see the operation end of an endoscope. When one or more operation systems have been arranged in multi-inner Endoscope, one positioning of such devices becomes still more complicated, and it is a vine. For example, when one inner Cavity of an endoscope has grasping tweezers in while and inner Cavity has a loop search wire, when a doctor positions the operation system of a request required to detect correctly, he will spend a great labor. Two devices may come to be involved. An operation end relative extension position cannot be decided in general with the endoscope usually used. Even if an operation end can be seen, since the view is parallel to an operation end, it, other instruments, or the depth relation between the organizations of a human body is undetectable. Since linear observation is essentially two dimensions, the image which a doctor observes cannot give depth information correctly. Detecting these positions, since this operation end is located in various relative extension or a retreat position if it puts in another way cannot be continued via the usual endoscope until the actual contact with the organization of a human body is obtained. Thus, when using an endoscope for effective medical treatment or diagnosis, the doctor has to use a guess to some extent, in order to avoid damaging an organization or missing a detection part. it must see, while being based on the endoscope which is inserting the textiles bunch for optical transmission, and another fault of the detecting method must enlarge the path of an endoscope enough inserting the textiles bunch for optical transmission -- they are things. This obstructs the effective medical detecting method. First, the externally caused injury experienced with letting the existing organ pass or advancing an endoscope endermically increases with the increase in the size of an endoscope. Flexibility is fewer as an endoscope becomes large (it becomes.). Another usual medical detecting method has adopted the catheter which is not Insertioning the textiles bunch for optical transmission to one of the lumina. A catheter is guided from the outside and progresses to bodily Cavity toward the target organization. For example, he can follow an endoscope to the final position, using X-rays (fluorescence line) or an ultrasonic wave as guidance. This method of positioning a catheter indirectly also has fault. Since the restored visible image shows Cavity of the actual inside of the body indirectly, it needs great elucidation art for positioning an operation end correctly and operating it. The family celebration detecting method by the present invention conquers such faults in the present Medical Service Law. The operation end of the catheter with which the present invention is advancing enables it to see the actual image relevant to the advance condition to the target organization. Since the textiles bunch for optical transmission is removed from the catheter, the path of a catheter can be made small or can increase the function alternatively. When making a path small, a catheter serves as flexibility extremely. The method of the present invention looks at an endoscope, while [ of a certain kind ] being used now when it brings close to a candidate organization through punching, and it is non-traumatism as compared with the endermic proximity method in the detecting method. Although various medical devices using the textiles for optical transmission have been developed, there is nothing in it that all showed the principle of the present invention. United States patent 3.961st of North Bouto (Northeved) and No. 621 are indicating the device consisting of the needle of long and slender Inclination cutting which has arranged to inside the tubular stiletto which can collect a biochemical sample from a human body. The textiles bunch for optical transmission is arranged in parallel with stiletto at the circumference that it should be used in order to draw stiletto to the target organization. A vacuum can be supplied via the thin air duct arranged the textiles bunch for optical transmission, and by turns. U.S. Pat. No. 4,269,192 of Matsuo (Matsuo) is indicating the medical implements with which an end consists of a tubular member by which slanting cutting is carried out. It emanates to that of a human body, LEA is activated with the intensity of the light subsequently reflected from the inspection part, and LEA takes out the signal of the intensity of the reflected ray which shows the position of the operation end of medical implements. The textiles for optical transmission are arranged in the direction of an axis in the operation tubular member. United States patent No. 3.556.085 of Takahashi (Takahashi) consists of a textiles bunch for optical transmission which carried out slanting cutting, and incorporates an expansion object lens and an eyepiece, and is indicating the microscope inserted in the human body. A position is possible for various lens systems so that magnification may be attained. This microscope is designed to use it with the operation medical implements arranged in the same housing in parallel with optical textiles. United States patent No. 3.941.121 of Olynga (Olinget) is indicating the endoscope of a byway including the needle of the hollow provided with the lens system, and the optical textiles bunch of image transmission in this needle. the channel which receives operation medical implements -- it is detailed -- it is provided in the electrode which stimulates the nerve of a core. The operation channel is arranged at the longitudinal direction at the textiles bunch for optical transmission, and parallel. United States patent No. 3.349.762 of Cape (Kapany) is indicating the medical implements which use optical textiles and measure the flow velocity of blood, in order to detect the intensity of the light transmitted by shedding blood. Intensity is measured by Fo I-pt and changed into analog voltage, i.e., a current output. United States patent No. 4.566.438 of lease (Lies6) incorporates the textiles bunch for optical transmission for returning the intensity and the color of catoptric light, and is indicating Strange needle so that it may explore the position at the tip of a needle. Diagonal cut of the optical textiles was carried out by the end, and they have closed the case with low evaporating pressure epoxy. Euphotic textiles adjoin the inclined end of an instrument and have a reflective surface. There is nothing that indicated the Medical treatment detecting method so that the very small textiles bunch for optical transmission might be inserted through inner Cavity of the needle positioned beforehand, in order that they may draw the operation end of the medical implements remotely, as all of the above-mentioned patent are directly visible in the tip of another medical implements. 3 ① 9 Greedy One example of the present invention advances partially through the female tube of existing [ a multi-lumen catheter ], Endermic insertion is carried out at the angle which exists in order that the needle which has arranged the blockaded sounding needle inside may make the tip of a catheter legible, Subsequently, it is the method that a catheter is carried forward to the tissue of the body used as a subject of examination, by exploring, removing a needle, and inserting the textiles bunch for optical transmission through inner Cavity of a needle and seeing directly from the textiles bunch for optical transmission continuously. One example of the medical device combination structure by the present invention is a needle of the byway which arranges the blockade sounding needle of removal Regret through there. Once a needle is located endermically, a sounding needle is removed, and in order that the textiles bunch for optical transmission may subsequently look at the advance condition of a multi-lumen catheter, it will be inserted through inner Cavity of a needle. An alternative example is connecting the textiles bunch for optical transmission to the screen of a cathode-ray tube or television, in order to see the real image of a catheter. The object of the present invention is to provide the tissue of the body which is the target of an inspection with the improvement jj method for positioning a catheter and operating it.

Drawing 4c is a figure showing the blockade sounding needle shown in Drawing 4b partially taken out from inner Cavity of the needle. Drawing 4d is a figure which takes out a blockade sounding needle completely, and is inserting the textiles bunch for optical transmission into the kidney through inner Cavity of a needle so that the position of the catheter to Kidney stones can be seen and in which showing the needle shown in Drawing 4. Drawing 4e is a figure showing the catheter after being advanced by putting a catheter on a Kidney stones part and observing via the textiles bunch for optical transmission. Example of Can not hurt-noodles (2) Hen A specific term is used, in order to describe an example with reference to [ the following ] the example shown in a figure so that it may be easy to understand the principle of the present invention. But the range of the present invention should not be limited by the example, and is understood to be that by which change of an illustration device and the application of others of the principle of correction and 4 inventions which are usually recollected by the specialist of technical 9 measure related to un-inventing also go into the uninvented range. If drawings are referred to in detail, tip 32 of am bunch 30 for 5 light transmission where Drawing 1 shows the fragmentary sectional view of needle 20 with which textiles bunch 30 for optical transmission is inserted can extend freely from tip 24 of needle 20. The first stage carries out Blowing, and the blockade sounding needle (not shown) inserted through inner Cavity 22 of needle 20 is used for positioning. The outside diameters of this needle are 18 gauges (0*049 inches (as for the path of], 12446 Sentin or less, and inner Cavity 22, it is preferred that it is below 0 - 039 inches (0 or 09906 cm).)). Cook Euro Rocical of Sling 7 sir for Indiana which is an object for one that combination 411 Construction of needle 20 and m Restraint 30 for optical transmission enforces the medical inspecting method concerning the suitable example of the present invention The needle of model designation 090020 which parrot volley Tenoto sells can be used. Drawing 2 shows needle 20 of Drawing 1 when the end face side is seen from the section of 2-2 line of Drawing 1, and textiles bunch 30 for optical transmission from tip 24 of needle 20. Each glass fiber 31 of textiles bunch 30 for optical transmission is ing in Show. It is necessary to make the outside diameter of textiles bunch 30 for optical transmission into what fits in easily in inner Cavity of needle 20. A textiles bunch for optical transmission which is marketed from Mitsubishi of Japan can be used. Drawing 3 shows the schematic diagram of a form useful for carrying out the present invention of textiles bunch 30 for optical transmission connected to light source 34, amplifier 36, and cathode-ray tube 38. Textiles bunch 30 for optical transmission consists of each glass fiber 31 of a 4000 name, and 4 used in order that about 1 to 1.5 in it% may transmit light from a light source to tip 32 of textiles bunch 30 for optical transmission, and this light irradiate with Cavity which a human body like the kidney selected. The 98.5 [ remaining ] to 99 of glass fiber 31% collects and transmits Cavity of a human body, or the configuration of the reflected light. Even amplifier 36 advances, and catoptric light is amplified about 200 times here, and is displayed on shade retrace line pipe 38. Thus, the real image from the inside of a human body is indirectly observable by man's eyes. The medical inspecting method enforced according to the suitable example of the present invention is shown from Drawing 4a up to Drawing e. Having used as an example the female pelvis which the partial diagrammatic view of the Cusp-like direction central section of a female pelvis is shown even in Drawing 40 from Drawing 4a, and shows the medical inspecting method of the present invention cannot limit the present invention, and it can apply the present invention also to a male equally. It is a partial diagrammatic view of the sectional view of Drawing 48 seen from near the b-b line from Drawing 4b up to Drawing 40. Generally, multi-inner Cavity catheter 40 is guided by X-rays (fluorescence fluoroscopy tfL) or an ultrasonic wave, and runs through the existing lumen as a ureteral catheter runs exactly to the position shown in Drawing 1. In a certain going on point, needle 20 of the byway provided with blockade sounding needle 26 is introduced endermically, and is positioned in the system of sets of kidney 51 which contains a kidney pelvis and Kidney cup, for example. Subsequently, it explores and needle 26 is removed, and textiles bunch 30 for optical transmission has inner Cavity 22 of a needle let it pass, and observes kidney 5J in a female tube, i.e., a suitable example. By observing through the combination structure of needle 20 and textiles bunch 30 for optical transmission which are shown in Drawing 1, the doctor can observe the tip as catheter 40 runs into kidney 51. Drawing 4a shows multi-inner Cavity catheter 40 already partially inserted through the existing lumen. First, a catheter is carried out to ureter 55 which has an inspection product part of kidney @51 from ureter opening 54 via bladder 53 to urethra 57. Catheter 40 of illustration is a multi-inner Cavity balloon catheter which has opening 44 at tip 42, inserts surgical instrument 46 via inner Cavity 43 connected with opening 44 at the tip in order to perform an operation, and is a vine. Although marketed from Cook Euro logical Incorrected of U.S. Indiana state Spencer as multi-inner Hollow canal catheter to this object, multi-inner Cavity catheter [ like ] 40 is useful. In this example, a surgeon treatment is removing Kidney stones 59 from kidney 51. Surgical instrument 46 is the State of Indiana. Spencer Tuck Euro Rocical The forceps for Kidney stone to market(ed) by considering it as model designation 011666 from parrot Holted as shown in a suitable example may be used. The alternative amount of accessories Wear can be used to the surgery method of other extensive kinds. The thing with the device of above-mentioned others contains the grasping forceps of 3 thru/or 4 prongs, Kozub, a rat tooth or alligator dentate forceps, a loop retriever, spiral or a common wire-like Kidney stones extraction machine, an electric oil crushed stone probe, etc. Inner Cavity 47 of illustrated catheter 40 is open for free passage with side port 48, in order to send fluid, i.e., carbon dioxide, various kinds of X ray contrast media, sterilization water, the salt solution for sterilization, etc. In order to discharge irrigation fluid, there is another inner Cavity 45. There is also another inner Cavity 41 which bends in order to make catheter 40 flexible, and accepts wire guide 49. as model designation 738415 -- the tuck Euro of State Spencer of Indiana -- logical Although marketed from parrot Holted, wire guide [ like ] 49 may be used to this object. Since the optical portion of catheter 40 is separated from catheter 40 and did the catheter with the byway, wide range functional inner Cavity was possible - Closed, or in the case of this example, the functionality of the great range is included in the single catheter. 11 which can be attained from the method of understanding the specialist in the medicine field for initial insertion of catheter 40 immediately, for example, a catheter, can be drawn to the point which is guided from the outside by guidance of X-rays (fluorescence fluoroscopy) or an ultrasonic wave, and is shown in Drawing 4a. the point which shows a catheter in Drawing 4a -- Distant (from -- or it -- Near (from -- it can insert to various points by the above-mentioned guidance.)) Drawing 4b shows catheter 40 after going on to Renal plate 56. Needle 20 which penetrated and inserted blockade sounding needle 26 is inserted endermically, and is located in the system of sets of the kidney. Drawing 4C shows needle 20 which removed blockade sounding needle 26 partially. Drawing 4d shows needle 20 after removing blockade sounding needle 26 completely. textiles bunch 30 for optical transmission is not inserted through inner Cavity of a needle -- By force -- it is. The inner side of kidney 51 including tip 42 of Kidney stones 59, kidney meat tissue, and catheter 40 is observable via textiles bunch 30 for optical transmission. Incident light is supplied via 60 from net 40 of glass fiber 31, and irradiates with the inner side of kidney one a51. It is reflected by the wall and the feature in the kidney, and light is returned to amplifier 36 by the remaining glass fibers 31, and is expanded by about 200 times there. In order that a doctor may observe the expanded image, it is displayed on screen 38. Guidance figure 4e shows catheter 40 in such a state where it is led, to the object, i.e., Kidney stones 59, using guidance wire 79 using the actual image in which the doctor was returned. The tip of multi-inner Cavity catheter 40 is drawn to Kidney stones 59. Surgical instrument 46 can blow up balloon 60 operated so that it may be shown at tip 42 of catheter 40 in the state where it has extended so much and Kidney stones may be continuously removed at it according to hope. a balloon -- swelling -- swelling -- the source of fluid -- it -- inner Cavity 62 and free passage To shake -- it is carried out by attaching like. Catheter 40 after removing successfully Kidney stone 59 which may use inner Cavity for pouring and discharge or performing required disposal so that medical processing may be performed if needed, In this case, it retreats to the outside of the body via []54 via bladder 53 and ureter 57 through the existing lumen which is ureter 55 between urethrae. After inserting catheter 40 in part in the example shown by Qe from Drawing 4a, needle 20 was inserted, but before inserting catheter 40, it is also possible as another example of the present invention to insert needle 20. The method according to the present invention is not limited to removal of Kidney stones, but can be immediately applied also to A tumor or the likeness externally caused injury of an imitation, an infection part, or the medical inspection disposal that, in addition to this, includes investigation of a doubtful part, or the investigation for surgical intervention medically. Surgical intervention is performed using the accessories of multi-inner Cavity catheter 40, and Cavity in irrigation. It is that applying the present invention to either the method enumerated upwards or the other methods is immediately considered by the specialist in the medicine field concerned. Blockade sounding needle 26 is inserted through inner Cavity 22 of a needle, and how to use needle 20 of inserting textiles bunch 30 for optical transmission is not continuously limited to common use with the catheter of single inner Cavity or multi-inner Cavity, The directions of others of the combination structure of needle 20 and textiles bunch 30 for optical transmission also become clear immediately at the specialist in the technical field concerned. The combination structure in particular of a needle and the textiles bunch for optical transmission is not limited to use by the urinary tract. In spite of supporting surgery intervention finally and not carrying out it, it is used for inspection of Cavity in the living body, and the combination structure of a needle / textiles bunch for ' light transmission is a vine. If it puts in another way, the combination structure of the needle / textiles bunch for ' light transmission by the present invention can be inserted in a female tube for the object of diagnosis in addition to use with a catheter or other medical devices. Although the present invention was shown in detail and has been explained in a drawing and the above-mentioned explanation, All the change which it is illustration, should consider the not restrictive thing in the characteristic, illustrated and described only the suitable example, and goes into the soul of the present invention, and correction (it is understood that it is a thing to protect as a = patent.)
