DETAILED DESCRIPTION

[0019] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be described clearly and completely below in combination with the drawings in the embodiments of the utility model.

[0020] The traction frame provided in the embodiments mainly aims to solve the problem that in the process of osteotomy, two parallel osteotomy surfaces are generally cut on the surface of metacarpal and phalangeal frame, then two people hold the two ends of the osteotomy surface to close, thus the method is relatively wasteful in manpower, and the following technical scheme is provided, which will be described in detail below in combination with the drawings. Figures 1-4 Detailed description:

[0021] The traction frame for metacarpal and phalangeal frame comprises a chamfered screw 1 with a plurality of moving blocks 2 threadedly connected to the surface, and fixed holes 4 are formed on the surfaces of two moving blocks 2. In use, the user needs to insert steel nails into the inner walls of the two fixed holes 4, then insert the steel nails into the surface of the patient's metacarpal and phalangeal frame, and then cut the metacarpal and phalangeal frame (i.e. cut two osteotomy surfaces on the surface of the metacarpal and phalangeal frame), then move one of the moving blocks 2 by the first adjusting unit 3, so as to drive one end of the two osteotomy surfaces to close, thereby effectively saving manpower resources. The main components of the first adjusting unit 3 comprise: a plurality of adjusting tubes 31 respectively rotatably inserted into the surfaces of the moving blocks 2, and a plurality of adjusting protrusions 32 are arranged on the surfaces of the adjusting tubes 31. In use, the user can drive the adjusting tubes 31 to rotate by respectively pinching the adjusting protrusions 32, so as to move the moving blocks 2.

[0022] The chamfered screw 1 is threadedly connected with a plurality of moving blocks 2 on the surface. In use, the user needs to adjust the positions of two moving blocks 2 by the first adjusting unit 3, then slide the two steel nails into the inner walls of the two fixed holes 4 and insert them into the surface of the patient's metacarpal and phalangeal frame, so as to limit the chamfered screw 1 on one side of the metacarpal and phalangeal frame, then cut the metacarpal and phalangeal frame (i.e. cut two osteotomy surfaces on the surface of the metacarpal and phalangeal frame), and finally adjust the movement of one of the moving blocks 2 by the first adjusting unit 3, so as to drive one end of the two osteotomy surfaces to close, thereby effectively saving manpower.

[0023] By setting two rotating rods 111 above the other moving block 2, the user rotates the threaded rod 113, which can control the spatial height of the guide groove 10. At the same time, the user rotates one of the rotating rods 111 and the guide rod 9, and then locks it by abutting the nut 115. This can realize the multidimensional adjustment of the position of the guide groove 10 to meet the cutting position requirements in different surgeries.

[0024] As shown in Figure 1 , Figure 3 , Figure 4 In some embodiments, the surfaces of the two moving blocks 2 are provided with cleaning grooves 5. In use, the user needs to slide the sliding block 6 on the inner wall of the two cleaning grooves 5, then thread the limiting bolts 7 on the surfaces of the two moving blocks 2, and make the limiting bolts 7 thread into the inner walls of the two cleaning grooves 5, respectively. This can limit the two sliding blocks 6 in the inner walls of the two cleaning grooves 5. Finally, the fixed bolts 8 are threaded on the surfaces of the two moving blocks 2, and the surfaces of the two fixed bolts 8 are threaded into the inner walls of the two cleaning grooves 5, respectively. In subsequent use, the user can slide the two steel nails into the fixed holes 4 on the surfaces of the two fixed bolts 8, respectively, and then insert them into the surface of the patient's metacarpal skeleton. In subsequent cleaning of the device, the limiting bolts 7 need to be removed first, then the two sliding blocks 6 are removed, and the inner wall of the cleaning groove 5 is cleaned. This split structure makes the threaded holes on the surfaces of the two moving blocks 2 and the two sliding blocks 6 not too deep, thereby facilitating subsequent cleaning operations.

[0025] As shown in Figure 1 and Figure 2As shown, in some embodiments, a guide rod 9 is arranged on one side of the other movable block 2, and in use, the user can adjust the position of the guide rod 9 through the second adjusting unit 11, further drive the guide groove 10 arranged on the surface of the guide rod 9 to move, and when the medical staff uses the cutting tool to cut the metacarpal and phalangeal skeleton of the patient, the cutting position can be adjusted by adjusting the position of the guide groove 10 (when cutting, the cutting tool needs to be inserted into the inner wall of the guide groove 10 to cut the metacarpal and phalangeal skeleton of the patient), and the cutting position is corrected, wherein the main components of the second adjusting unit 11 are: two rotating rods 111 arranged above the other movable block 2, and a lifting groove 112 is formed in the surface of the other movable block 2, and a threaded rod 113 is rotatably inserted into the inner wall of the lifting groove 112, in use, the user rotates the threaded rod 113, which can drive one of the rotating rods 111 threaded on the surface of the threaded rod 113 to lift, and because one of the rotating rods 111 and the surface of the guide rod 9 are fixedly installed with a fixed rod 114, and the surfaces of the two fixed rods 114 are slidingly inserted into the surface of the other rotating rod 111 and are threaded with a resisting nut 115, therefore, the user can not only adjust the spatial height of the guide rod 9 by rotating the threaded rod 113, but also can adjust the two-dimensional inclination angle of the guide rod 9 by rotating the guide rod 9 and one of the rotating rods 111 respectively, further realize the multi-dimensional adjustment of the position of the guide rod 9 (guide groove 10), and facilitate the subsequent operation.

[0026] As Figure 1 shown, in some embodiments, in use, the user needs to rotate a plurality of resisting bolts 12 threaded on the surface of a plurality of movable blocks 2 respectively, so that the plurality of resisting bolts 12 abut against the surface of the chamfered screw rod 1, so as to realize the reinforcement and positioning of the plurality of movable blocks 2 on the surface of the chamfered screw rod 1.

[0027] The working process of the utility model is as follows:

[0028] Firstly, the user needs to rotate two adjusting pipes 31, drive two fixed holes 4 to move, and then insert two steel nails into the surface of the two fixed holes 4, so that the two steel nails are inserted into the surface of the metacarpal and phalangeal skeleton, and the positioning of the chamfered screw rod 1 on one side of the metacarpal and phalangeal skeleton can be realized.

[0029] Secondly, by setting two rotating rods 111 above the other mobile block 2, the user rotates the threaded rod 113, that is, the space height of the guide groove 10 can be controlled, and then the user rotates one of the rotating rods 111 and the guide rod 9, and then locks through the abutting nut 115, that is, the multi-dimensional adjustment of the position of the guide groove 10 can be realized, so as to cut the position required in different operations, finally, the cutting tool is inserted into the inner wall of the guide groove 10, and the precise cutting of the metacarpal and phalangeal frame surface (a bone cutting surface is cut out) can be realized. Similarly, the user can adjust the cutting position of the other bone cutting surface through the above-mentioned method, and finally the user can adjust the positions of the two mobile blocks 2, so that the two ends of the bone cutting surface can be closed, thereby completing the operation.

[0030] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
