This conventional cytological examination brush for seed endoscopes was constituted, for example, as shown in Drawing 1. To namely, the first portion of comparatively short wire 2 for brush attachment which conventional cytological examination brush 1 for endoscopes twisted two elastic wire rods, and was formed, Brush section 4 is formed in the portion by inserting hair 3 in Rubbing which the wire 2 twists, The latter half part of wire 2 for brush attachment which forms this brush section 4 is thrust at the tip of operation wire 5 which forms an elastic wire rod in the shape of a screw type, and the principal part is constituted by uniting this wire 2 for brush attachment with operation wire 5. Round head metal fittings 6 for preventing the wound of the wall in the abdominal cavity are attached at the tip of brush section 4. It faces unifying the above-mentioned wire 2 for brush attachment, and operation wire 5, Since he is trying for the interval of the mountain of two elastic wire rods and mountain which were formed that wire 2 for brush attachment twists, i.e., Pitch, to correspond to Pitch of the shape of a screw type of operation wire 5, Wire 2 will twist, the mountain of shape will eat in the valley of the shape of a screw type of operation wire 5, and wire 2 will be fixed to operation wire 5 by twist lump of the above-mentioned wire 2 for brush attachment. As shown in Drawing 2, other conventional cytological examination brushes 7 for endoscopes are, Ends 2a and 2b of two elastic wire rods in the rear end part of the above-mentioned wire 2 for brush attachment are turned outside, and are bent, these ends 2a and 2b are put between elastic screw type-like wire rods from the tip of the above-mentioned operation wire 5, and it is next, The above-mentioned wire 2 for brush attachment was twisted, and it fixed to operation wire 5 and was constituted. However, cytological examination brushes 1 and 7 for endoscopes which unite wire 2 for brush attachment with operation wire 5 by twist lump as mentioned above, The thing which make brush section 4 rotate the brush section in the direction of arrow A of illustration when inserting in channel 8 for treatment implement insertion of an endoscope, as all show in Drawing 3 at the time of the use and for which it twists and movement is added is Overtake, Or in order to twine the cell around hair 3 of brush section 4 efficiently when extracting the Organization cell of wall 9 in the raw abdominal cavity as shown in Drawing 4, When rotational movement of the direction shown by arrows B other than Motion before and after meeting in the direction of an axis is added, it is at this time, A risk of two elastic wire rods of the above-mentioned wire 2 for brush attachment twisting [ the hand of cut of the above-mentioned cytological examination brushes 1 and 7 ], and the above-mentioned wire 2 for brushes escaping from the front end of operation wire 5, and dropping out in the raw abdominal cavity, when contrary to a direction is Oh. The object of the present invention bends the tip of the wire which has elasticity in view of the above-mentioned conventional fault, forms the brush holder of the shape of a closed loop which can be opened and closed freely, and is to provide the cytological examination brush for endoscopes which attached the brush member which comes to transplant hair at this brush holder radiately enabling free attachment and detachment. Hereinafter, the example of illustration explains the present invention. Drawing 5 is a front view of the cytological examination brush for endoscopes in which one example of the present invention is shown. This cytological examination brush 11 for endoscopes is constituted by operation wire 12 which has one flexibility, and brush member 14 attached to brush holder 13 formed in the tip part of this operation wire 12 enabling free attachment and detachment. the above-mentioned operation wire 12 is shown in Drawing 6 -- as -- one -- true -- bending the existing direct flexible elastic wire rod right-angled at four places of the tip portion, and contacting the latest straight part 12a to the main straight part 12e of a basis Brush holder 13 of the shape of a rectangular closed loop is formed by straight parts 12b, 12c, and 12d. Other portions are maintained at the Masanao shape as they are, and a rear end part of the main straight part 12e is final controlling element 12f and intermediary To have by the side of a hand. as shown in Drawing 7 A, the above-mentioned brush member 14 aligns radiately hair 15 which forms the brush member 14, and polymerizes -- as a whole -- short -- after being cylindrical, it is shown in Drawing 7 B -- as It adheres with adhesives and only the central part is made into bearing part 16, and circular bearing hole 16a is drilled in this bearing part 16, and it is constituted. Without using adhesives, when hair 15 is made of thermoplastics, such as nylon resin, brush member 14 forms bearing part 16 by thermal melting arrival, and it may make it drill bearing hole 16a in this. And brush member 14 manufactured by doing in this way is attached to brush holder 13 of the tip part of the above-mentioned operation wire 12 after it is judged so that it may become predetermined size shape about the surroundings of hair 15, and being orthopedically operated in the shape of a short cylindrical shape. Brush member 14 is faced attaching to brush holder 13, As shown in Drawing 8, straight part 12a of brush holder 13 is extended in the direction of arrow C which resists the spring habit of the brush holder 13, and it makes estrange from the main straight part 12e of operation wire 12, and it is in this state, The tip of the above-mentioned straight part 12a is put in bearing hole 16a of the above-mentioned brush member 14, each straight part 12a, 12b, and 12c of brush holder 13 is moved, and this brush member 14 is located in straight part 12d. Then, the thing for which the latest above-mentioned straight part 12a is returned to the state of contacting the main straight part 12e, As shown in Drawing 5 of the above, brush holder 13 becomes closed loop-like again, and brush member 14 will be in the state where it is held in straight part 12d for the said pivots by using straight part 12d of brush holder 13 as a pivot enabling free rotation. Next, an operation of cytological examination brush 11 for endoscopes constituted as mentioned above is explained. First, insert the above-mentioned cytological examination brush 11 into channel 8 (refer to the 3rd figure) for treatment implement insertion of an endoscope, brush member 14 is made to project from the tip part of an endoscope like the conventional case, and the brush member 14 is made to weld by pressure to wall 9 in the abdominal cavity, as shown in Drawing 9. Next, if operation wire 12 is made to Motion to the longitudinal direction of the wire 12 approximately, brush member 14 will rotate, while rubbing wall 9 in the abdominal cavity by hair 15 centering on straight part 12d for pivots. For this reason, Organization which forms wall 9 in the abdominal cavity at the tip of hair 15 is hooked, and a Organization cell is involved in hair 15. Therefore, if operation wire 12 is made to Motion greatly approximately, scratch extraction of Across and many Organization cells will be carried out at all the circumferences of brush member 14. Since the Keep it cage and brush member 14 are certainly supported in the shape of a rectangle closed loop by the above-mentioned straight part 12d for pivots at this time, the above-mentioned brush holder 13 does not drop out of brush holder 13. Drawing 10 is a side view which made the section the bearing part of the brush holder of the cytological examination brush for endoscopes in which other examples of the present invention are shown. Straight part 12d for pivots of brush holder 13A for this cytological examination brush 17 to penetrate this bearing hole 16b, and support [ bearing hole 16b of the shape of a polygon, such as a quadrangle, is formed in bearing part 16 of brush member 14A, and ] the above-mentioned brush member 14A₀According to the shape of the above-mentioned bearing hole 16b, it comes to form Section shape in the shape of a polygon. About an operation of cytological examination brush 17 for endoscopes constituted in this way, When insert the cytological examination brush 17 into the raw abdominal cavity through channel 8 (refer to the 3rd figure) for treatment implement insertion of an endoscope, brush member 14A is made to weld by pressure to wall 9 in the abdominal cavity and operation wire 12 is made to Motion approximately, this brush member 14A is straight part 12d for pivots.₀It is alike, and it receives, and since it cannot rotate freely, the brush member 14A is rubbed by wall 9 in the abdominal cavity, without rotating. For this reason, even if operation wire 12 order Motion is not so large, the tip of hair 15 of brush member 14A scrapes the Organization cell of wall 9 in the abdominal cavity strongly, and many cells come to adhere to hair 15 of this brush member 14A. Judge the surroundings of hair 15 so that the woolen length may become fixed, and it operates orthopedically in the shape of a short cylindrical shape, and also the above-mentioned brush member 14 is decision plastic surgery, For example, brush member 14B of the Fallen column shape shown in Drawing 11, brush member 14C of the triangular prism shape shown in Drawing 12, and brush member 14D of the hexagon pillar shape shown in Drawing 13 can be manufactured, and this can be used like the above-mentioned brush members 14 and 14A. These brush members 14B, 14C, and 14D have the advantage that connection of a Organization cell becomes good in the portion of a lug, rather than brush members 14 and 14A of the above-mentioned circle shape. The end of hair 15 put in order by being parallel as other brush members 14, for example as shown in Drawing 14 A, It may be made to form brush member 14E by bending the clamp member 18 for what was inserted and fixed by clamp member 18 consisting of the thin metal plate or plastic sheet bent so that a section might become U character-like in circle shape, as shown in Drawing 14 B. Clamp member 18 is bent in circle shape, by joining the ends, the clamp member 18 serves as bearing part 18A which has bearing hole 18a at the center, and hair 15 comes to be radiately arranged by the circumference. It implants or pastes up, hair 15 is fused to the peripheral face of short cylinder-shaped bearing member 19 by which bearing hole 19a was drilled in the center, and it may be made to form brush member 14F, as shown in Drawing 15. Arbitrary things, such as metal, a plastic, and a tree, are used as the quality of the material of this bearing member 19. As the shape of the brush holder of the shape of a closed loop formed in the tip part of the above-mentioned operation wire 12, It can be considered as arbitrary shape, such as brush holder 13B of the shape of a triangle shown in Drawing 16 besides brush holder 13 of the shape of a rectangle shown in Drawing 6 of the above, and brush holder 13C of the circle shape shown in Drawing 17. And as for these brush holders 13B and 13C, all are straight parts 12a at the tip.₁,12a₂It is each main straight part 12e.₁,12e₂Along intermediary contact is carried out, and the closed loop is formed, therefore it is the above-mentioned straight part 12a.₁The main straight part 12e₁Between, the above-mentioned straight part 12a₂The main straight part 12e₂The brush member of various shape can be made to detach and attach to these brush holders 13B and 13C simply by extending between the same with having been shown in Drawing 8. The brush member attached to these brush holders 13B and 13C does not fall out from the brush holder during that use by being a spring habit or returning these brush holders 13B and 13C that changed to the shape of the original closed loop by external force. As stated above, in the present invention, one wire is bent, a closed loop-like brush holder is formed at that tip, and a brush member is made to hold to this brush holder. Therefore, a danger that a brush member will fall out like before also in To join does not have movement by operation of the direction of several kinds in a wire. since the closed loop of a brush holder can be opened and closed freely -- a brush member that a brush member can be detached and attached freely and old -- a new thing -- or the brush member of various shape can be exchanged easily and the effect which was excellent in the ability to have cheap composition, etc. is demonstrated.
