The outside of the rotating rings 405 and the hanging rings 407 are bolted to steel wire ropes 406. The traction sleeve 2 is equipped with a temperature control module 5.

[0020] Specifically, the device utilizes posture adjustment module 4 to adjust the device according to the patient's body shape when performing bone traction, thereby adapting the device to different patients' conditions, improving the patient's user experience, ensuring that the fracture ends remain aligned, significantly increasing the device's bone traction effect on the patient, and promoting wound healing.

[0021] Reference Figure 3 , Figure 4 and Figure 5In a preferred embodiment, a mounting plate 402 is provided above the traction sleeve 2. A cross support frame 403 is bolted to the bottom of the mounting plate 402. The cross support frame 403 has four symmetrical notches on its exterior. Guide rollers 404 are rotatably connected to each notch via bearings. The exterior of each guide roller 404 is in contact with the exterior of the wire rope 406 on the same side. An air pump 410 is bolted to the exterior of the traction sleeve 2. The output end of the air pump 410 is connected to a three-way pipe 411 via a conduit. Two symmetrical circular holes are provided on the traction sleeve 2. The three-way pipe 411 is located away from the two ends of the air pump 410. Each shaft passes through a circular hole and communicates with a positioning airbag 408 on the same side. Four symmetrical rotating shafts 412 are rotatably connected to the upper side of the mounting plate 402 via bearings. Each rotating shaft 412 is bolted to a winding roller 420. The end of the wire rope 406 away from the traction sleeve 2 is bolted to the outside of the winding roller 420 on the same side. Each rotating shaft 412 is rotatably connected to a fixing plate 413 via bearings. The outside of the fixing plate 413 is bolted to the upper side of the mounting plate 402. Flat-mouth gears 414 are bolted to the outside of each of the four rotating shafts 412. The bottom of the flat-mouth gears 414 is connected to the fixing plate 412. The upper sides of all three plates 413 are rotatably connected via bearings. Each flat-jaw gear 414 has a locking ring 415 on its exterior. The bottom of each locking ring 415 is slidably connected to the exterior of the fixing plate 413, and the inner wall of each locking ring 415 is bolted to a limiting rack 418. The exterior of each limiting rack 418 is engaged with the exterior of the flat-jaw gear 414 on the same side. Each of the four fixing plates 413 has a guide buckle 416 bolted to its exterior. The exterior of each guide buckle 416 is slidably connected to the inner wall of the locking ring 415 on the same side. Each guide buckle 416 has two symmetrical springs 417 bolted to its exterior. The springs 417 are located away from the guide ring 414. One end of the latch 416 is bolted to the inner wall of the locking ring 415 on the same side, and the upper side of the rotating shaft 412 is bolted to a knob 419; the upper side of the fixing frame 1 is bolted to two symmetrical bosses, and the two bosses are rotatably connected to the same threaded rod 427 by bearings. One side of the threaded rod 427 is bolted to a handle 429, and the opposite side of the two bosses is bolted to the same limiting rod 428. The limiting rod 428 and the threaded rod 427 are provided with the same movable platform 401. The bottom of the movable platform 401 is bolted to the upper side of the mounting plate 402.The external sliding connection of the fixing frame 1 consists of two symmetrical slide rails 421. The slide rails 421 are bolted to the side opposite to the treatment bed 3. The fixing frame 1 has two symmetrical slots, each housing a lead screw 424 and a round rod 425. The outer surfaces of both the lead screw 424 and the round rod 425 are rotatably connected to the inner wall of the slide rail 421 on the same side via bearings. A handle 426 is bolted to one side of the lead screw 424. The fixing frame 1 has two symmetrical insertion holes, each containing a sliding pin 423. Multiple equally spaced slots 422 are provided on the upper side of both slide rails 421, and the bottoms of the pins 423 are inserted into the inner wall of the slots 422.

[0022] In specific application scenarios, the posture adjustment module 4 is mainly used for the posture adjustment stage in the posture adjustment process. That is, the posture adjustment module 4 uses the rotating ring 405, the hanging ring 407 and the steel wire rope 406 to enable the device to control the tilt and angle rotation of the traction sleeve 2, so that the device can adjust the angle of bone traction according to the specific situation of the patient. Using the positioning airbag 408, the lifting airbag 409, the air pump 410 and the three-way tube 411, after the patient's hand or leg enters the traction sleeve 2, the affected area is fixed in the traction sleeve 2 by inflation, reducing the situation where the fracture ends cannot be kept aligned due to the patient's shaking. Using the flat gear 414, the locking ring 415, the spring 417 and the limiting rack 418, the length of the steel wire rope 406 can be locked after the posture adjustment of the traction sleeve 2, thereby ensuring that the posture adjustment of the traction sleeve 2 is always effective and avoiding frequent adjustments after dislocation.

[0023] Reference Figure 6 and Figure 7In a preferred embodiment, the temperature control module 5 includes a receiving frame 501. The bottom of the receiving frame 501 is bolted to the outside of the traction sleeve 2. A narrow opening is provided on one side of the receiving frame 501. A main air duct 502 is bolted to the inner wall of the opening. Two symmetrical slots are provided on the outside of the main air duct 502. Secondary air ducts 504 are bolted to the inner walls of each slot. A rectangular opening and two symmetrical rectangular narrow openings are provided on the outside of the traction sleeve 2. The outside of the main air duct 502 is inserted into the inner wall of the rectangular opening, and the outside of each of the secondary air ducts 504 is inserted into the rectangular narrow opening. A top guide pipe 503 is bolted to the end of the main air duct 502 away from the receiving frame 501, and the end of the secondary air ducts 504 away from the main air duct 502 is bolted to the other end. All are bolted to side guide pipes 505, which are connected to secondary air guide pipes 504. Top guide pipe 503 is connected to main air guide pipe 502. Top guide pipe 503 and side guide pipe 505 are located between positioning airbag 408 and lifting airbag 409. Multiple equally spaced oblique grooves 506 are opened on the outside of top guide pipe 503 and side guide pipe 505. Rotary motor 507 is bolted to the inner wall of housing frame 501. Fan 508 is connected to the output end of rotary motor 507 through coupling. Protective cover 510 is bolted to the upper side of housing frame 501. Heating wire 509 is bolted to the inner wall of protective cover 510. Heating wire 509 is located above fan 508.

[0024] In specific application scenarios, the temperature control module 5 is mainly used for the temperature control link in the temperature control process. That is, the temperature control module 5 can effectively heat or cool the space inside the traction sleeve 2 by using the heating wire 509, the rotating motor 507 and the fan 508, thereby ensuring the comfort of the patient when using the device. The top guide tube 503, the side guide tube 505 and the inclined groove 506 can evenly diffuse the hot and cold air delivered into the traction sleeve 2, thereby ensuring the temperature uniformity inside the traction sleeve 2.

[0025] Working principle: After the patient lies on the treatment bed 3, according to the patient's fracture location, the pin 423 is pulled out, and the handle 426 is turned to rotate the screw 424, which drives the fixation frame 1 to move on the slide rail 421. After the movement is completed, the pin 423 is inserted into the slot 422, and the handle 429 is turned to rotate the threaded rod 427, which moves the movable table 401 on the threaded rod 427, allowing the patient's hand or leg to be placed into the traction sleeve 2. This allows the patient's hands or legs to rest on the support airbag 409. The air pump 410 is activated, injecting air into the positioning airbag 408 via the air cylinder tee 411. This causes the positioning airbag 408 to inflate, thus fitting snugly against the patient's hands or legs in conjunction with the support airbag 409. Depending on the patient's height or body type, the spring force of the spring 417 is overcome, pushing the locking ring 415. This releases the locking rack 418 from the flat gear 414. The knob 419 is then rotated. Rotating the rotating shaft 412 causes the winding roller 420 to release or wind the wire rope 406, allowing the wire rope 406 to pull or loosen the rotating ring 405 or the lifting ring 407, enabling the traction sleeve 2 to tilt back and forth and rotate left and right, thus adapting to the patient. When the patient's affected area is in the traction sleeve 2 for a long time, if the ambient temperature is high, the rotating motor 507 is started, which drives the fan 508 to rotate, delivering cold air from the outside through the protective cover 510 to the main air duct 502. Through the separation of the secondary air duct 504, the air enters the top guide duct 503 and the side guide duct 505 in sequence. Guided by the inclined groove 506, the air blows from one end of the traction sleeve 2 to the other, thus carrying away the hot air inside the traction sleeve 2. When the ambient temperature is low, the heating wire 509 is started to heat the air entering the receiving frame 501, and the above steps are repeated to heat the inside of the traction sleeve 2.

[0026] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
