Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-6 As shown, an orthopedic traction device includes a mounting plate 1, on which a rotating structure 2 is mounted. The rotating structure 2 includes a rotating shaft 201, which is fixedly connected to the mounting plate 1. Multiple slots 202 are arranged in a circular array on the rotating shaft 201. A fixing post 7 is rotatably connected to the outside of the rotating shaft 201. A locking rod 203 is slidably connected to the fixing post 7, with one of the slots 202 engaging with the locking rod 203. An adjustment structure 3 is mounted on the fixing post 7, which includes a sleeve rod 301. A sleeve rod 301 is slidably connected inside the sleeve rod 301, and a slide rod 302 is slidably connected inside the sleeve rod 301. A first pull plate 204 is fixedly connected to the end of the locking rod 203. A first tension spring 205 is fixedly connected between the first pull plate 204 and the fixed column 7. A limit structure 5 is installed on the sleeve rod 301, and a tension structure 4 is installed on the slide rod 302. By rotating the fixed column 7 around the rotating shaft 201, the angle of the fixed column 7 can be quickly adjusted without disassembling the mounting plate 1, making the operation simpler and more flexible and improving the operating efficiency.

[0024] As a technical optimization of this utility model, an anti-detachment ring 206 is fixedly connected to the clamping rod 203, and the anti-detachment ring 206 is slidably connected to the fixing post 7. The anti-detachment ring 206 prevents the clamping rod 203 from slipping off the fixing post 7 after being pulled out excessively during operation, thus increasing the stability of the clamping rod 203.

[0025] As a technical optimization of this utility model, a lead screw 303 is rotatably connected inside the sleeve rod 301. The lead screw 303 is threadedly connected to the slide rod 302, and a knob 304 is fixedly connected to the end of the lead screw 303. By driving the sleeve rod 301 to slide through the lead screw 303, the height of the traction device can be finely adjusted again after the height of the sleeve rod 301 is quickly adjusted, making the height adjustment of the traction device more precise.

[0026] As a technical optimization of this utility model, the limiting structure 5 includes a limiting groove 501. Multiple limiting grooves 501 are equidistantly provided on the sleeve rod 301. A limiting rod 502 is engaged within one of the limiting grooves 501. The limiting rod 502 is slidably connected to the fixed post 7. A second pull plate 503 is fixedly connected to the end of the limiting rod 502. A second tension spring 504 is fixedly connected between the second pull plate 503 and the fixed post 7. An anti-detachment block 505 is fixedly connected to the limiting rod 502, and the anti-detachment block 505 is slidably connected to the fixed post 7. The limiting structure 5 limits the sleeve rod 301, facilitating quick adjustment of the height of the sleeve rod 301.

[0027] As a technical optimization of this utility model, the traction structure 4 includes a crossbar 401. The top end of the slide bar 302 is fixedly connected to the crossbar 401. Multiple through holes 402 are equidistantly opened on the crossbar 401. A hanging ring 403 is fastened in one of the through holes 402. A tensioner 404 is installed at the bottom end of the hanging ring 403. A connecting plate 405 is fixedly connected to the bottom end of the tensioner 404. Five finger sleeves 406 are installed on the connecting plate 405. The crossbar 401 and the slide bar 302 are perpendicular to each other, and the crossbar 401 and the finger sleeves 406 are perpendicular to each other. When the patient's fingers are locked in the finger sleeves 406, the patient's fingers drive the connecting plate 405 to move downward through the finger sleeves 406. The reading of the tensioner 404 changes. The pressure applied to the fingers is controlled according to the change in the reading of the tensioner 404, thereby improving the traction training effect of the fingers and wrist.

[0028] As a technical optimization of this utility model, a scale bar 6 is provided on the fixing post 7, and the fixing post 7 is perpendicular to the mounting plate 1; the scale bar 6 facilitates the quick adjustment of the height of the sleeve 301 according to the length of the patient's wrist, making the operation more convenient and precise.

[0029] In use, the mounting plate 1 is first fixed to the operating table of the operating table or treatment table with bolts. Pulling the first pull plate 204 outward causes the first pull plate 204 to extend the first tension spring 205. Simultaneously, the first pull plate 204 causes the locking rod 203 to slide out of the slot 202 on the rotating shaft 201, thus releasing the fixation of the fixing column 7. Then, the fixing column 7 is rotated to a suitable angle for the current patient. The first pull plate 204 is then released, at which point the first tension spring 205 returns to its original position, simultaneously causing the locking rod 203 to slide out of the slot 202 on the rotating shaft 201. 3. Slide the device into the slot 202 to limit the fixing post 7, fixing its angle and preventing rotation during use. Then, use the strap to fix the patient's wrist to the fixing post 7, thus completing the wrist fixation. The operation is simple and flexible, and the angle of the fixing post 7 can be quickly adjusted, making the traction device more convenient and comfortable to use. When it is necessary to adjust the height of the traction device according to the wrist length of different patients, pull the second pull plate 503. The second pull plate 503 drives the limiting rod 502 from the limit position. The sleeve rod 301 slides out of the slot 501, and at the same time, the second pull plate 503 drives the second tension spring 504 to extend, thereby releasing the limit on the sleeve rod 301. Then, the sleeve rod 301 slides quickly within the fixed column 7. After the height of the sleeve rod 301 is adjusted, the second pull plate 503 is released, and the second tension spring 504 returns to its original position after losing tension, causing the limit rod 502 to engage in the limit slot 501, preventing the sleeve rod 301 from sliding up and down. By limiting the sleeve rod 301 through the limit structure 5, the approximate height of the traction device can be quickly adjusted. Then, the knob 304 is rotated. The knob 304 drives the lead screw 303 to rotate, and the lead screw 303 thread drives the slide bar 302 to slide, thereby making a secondary fine adjustment to the height of the traction device, so that the height of the traction device can be more accurately adapted to different patients, and thus the traction device can provide better traction for the patient's wrist. Then, the patient's fingers are locked in the finger sleeve 406. The patient's fingers drive the connecting plate 405 to move down through the finger sleeve 406, and the reading of the tensioner 4 changes. The pressure applied to the fingers is controlled according to the change in the reading of the tensioner 404, thereby improving the traction training effect of the fingers and wrist.
