[0024] For examples, see Figure 1-3 This utility model provides a technical solution:

[0025] A wrist arthroscopic traction frame includes a fixed frame 1, a lead screw 2 threaded at the bottom of the fixed frame 1, a fixed plate 3 rotatably mounted on the upper end of the lead screw 2 passing through the fixed frame 1, an auxiliary component 4 mounted on the base surface of the fixed frame 1, an adjusting sleeve 5 mounted on the upper side of the auxiliary component 4, an adjusting seat 6 mounted on the upper end of the adjusting sleeve 5, an adjusting rod 7 slidably mounted inside the adjusting sleeve 5, an adjusting cap 8 threaded at the upper end of the adjusting seat 6, a telescopic sleeve 9 mounted on the upper end of the adjusting rod 7, a telescopic cap 10 rotatably mounted on the front end of the telescopic sleeve 9, a telescopic rod 11 mounted inside the telescopic sleeve 9, a connecting rope 12 mounted on the lower end of the telescopic rod 11, and a fixing finger sleeve 13 mounted on the lower end of the connecting rope 12.

[0026] In this embodiment, the auxiliary component 4 includes a support base 401. A threaded rod 402 is threaded on the upper side of the back of the support base 401, and a limiting rod 403 is slidably provided on the lower side of the back of the support base 401. The rear ends of the threaded rod 402 and the limiting rod 403 pass through the support base 401 and are respectively provided with an auxiliary plate 404. The left side of the auxiliary plate 404 is symmetrically provided with fixing grooves 405, and the right side of the auxiliary plate 404 is symmetrically provided with fixing straps 406. The left side of the base surface of the fixing strap 406 is provided with a first adhesive piece 407, and the right side of the base surface of the fixing strap 406 is provided with a second adhesive piece 408.

[0027] The fixing frame 1 has a U-shaped structure, and the base surface of the fixing plate 3 is provided with an anti-slip pad to increase friction and make it more stable during fixing. The bottom of the support base 401 is fixedly connected to the base surface of the fixing frame 1, the lower end of the adjusting rod 7 is fixedly connected to the base surface of the support base 401, the upper side of the adjusting base 6 has a "reduced diameter ring" structure, the telescopic rod 11 is threadedly connected to the telescopic cap 10, the front end of the threaded rod 402 is rotatably connected to the back of the auxiliary plate 404, and the first adhesive piece 407 is made of Velcro with a rough surface. The second adhesive piece 408 is made of Velcro with a hook-and-loop fastener. By setting the auxiliary component 4 on the wrist arthroscopic traction frame, the patient's forearm is placed inside the auxiliary plate 404. The patient's forearm can be fixed inside the auxiliary plate 404 by the fixing strap 406. Rotating the threaded rod 402 can move the auxiliary plate 404, thereby adjusting the position of the auxiliary plate 404 as needed to better fix the patient's forearm, which is more conducive to the operation of the surgery. The overall device has a simple structure, is easy to operate, and is more practical.

[0028] The working process of this utility model is as follows: When using the wrist arthroscopic surgical traction frame, firstly, the fixing frame 1 is attached to the patient's bed. Then, the lead screw 2 is rotated. Since the lead screw 2 is threadedly connected to the fixing frame 1, the rotation of the lead screw 2 drives the fixing plate 3 to move. The fixing plate 3 can fix the whole structure. Then, the height of the fixing finger sleeve 13 is adjusted as needed. During adjustment, the adjusting cap 8 is loosened. After the adjusting cap 8 is loosened, the upper side of the adjusting seat 6 unfolds. Then, the telescopic rod 11 is slid and adjusted to the appropriate height as needed. After that, the adjusting cap 8 is rotated to fix it. Then, the front and rear position of the fixing finger sleeve 13 is adjusted. During adjustment, the telescopic cap 10 is rotated. Since the telescopic cap 10 is rotatably connected to the telescopic sleeve 9 and the telescopic cap 10 is threadedly connected to the telescopic rod 11, the telescopic cap 10 drives the telescopic rod 11 to move when it rotates. It can be adjusted to a suitable position as needed. Then, the threaded rod 402 is rotated, and the threaded rod 402 drives the auxiliary plate 404 to move when it rotates. After it is moved to a suitable position as needed, the patient's forearm is placed inside the auxiliary plate 404. The fixing strap 406 is passed through the fixing groove 405 and fixed by the first adhesive piece 407 and the second adhesive piece 408, so that the patient's forearm can be better fixed, which is more conducive to the operation of the surgery.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
