Auxiliary recovery of the fixation device after artificial hip joint surgery, the fixation method of the fixation device, the specific steps are as follows:

S1: Firstly, the waist belt 1 is fixed on the waist of the human body, and then the legs are put into the inside of the leg guard 5 and covered with the belt 701. The patient rotates the knob 801 to make the second threaded rod 802 rotate, and the second threaded sleeve 803 is restricted by the connection box 702 and cannot follow. Rotate, so the second threaded rod 802 rotates to make the second threaded sleeve 803 move downward, the second threaded sleeve 803 drives the connecting frame 804 downward, the lower pressing shaft 805 moves with the connecting frame 804, and the lower pressing shaft 805 presses the belt 701 downward, Reduce the length of the belt 701 from the leg guard 5 to the square hole block 6 to achieve a fixed effect;

S2: Then, under the condition of constant length, as the patient walks, the state of stretching and tightening of the thigh muscles changes. At this time, the circumference of the legs will change, because the hip joint rotates during walking. , the square support 408 rotates with the first threaded rod 407 as the center of the circle, the square support 408 drives the connection box 702 to rotate, and the connection box 702 also rotates with the first threaded rod 407 as the center of the circle. Since the position of the adjustment frame 3 is fixed, the cylindrical teeth 401 The position of the connecting box 702 is fixed, and the connection box 702 rotates, so that the guide shaft 703 and the cylindrical tooth 401 produce relative motion, the fixed guide shaft 703 will rotate counterclockwise, and the rewinding belt 701 is released. When it is in an upright state, the rewinding shaft 704 is rewound The belt 701, in the state of raising the leg, releases the rolled belt 701 to judge the stretching and tightening state of the muscles according to the walking state, releases the belt 701 to avoid excessive compression and damage to the hip joint after surgery, and the wire shaft 703 plays a role Guiding effect, avoid excessive friction damage;

S3: Then the person walks, the hip turns, the square bracket 408 rotates with the first threaded rod 407 as the center, the first threaded rod 407 rotates relative to the second threaded sleeve 406, and the second threaded sleeve 406 starts to move toward the direction of the cylindrical tooth 401 Move, because the right-angle track 405 is fixed with the square bracket 408, the right-angle track 405 plays a limiting effect, preventing the second threaded sleeve 406 from following the rotation, and the second threaded sleeve 406 moves toward the direction of the cylindrical tooth 401 with the friction disc 403, along with The larger the rotation angle of the hip rotation, the larger the area of the friction disc 403 entering the interior of the cylindrical tooth 401, so the greater the rotational damping between the friction disc 403 and the cylindrical tooth 401, giving the patient rotational resistance and avoiding excessive rotation of the hip joint;

S4: When the angle between the hip joint and the vertical plane is 60 degrees, the friction disc 403 completely enters the cylindrical tooth 401, and the blocking block 404 on the outer wall of the friction disc 403 will be completely inserted into the interior of the cylindrical tooth 401, and the blocking block 404 will In contact with the blocking frame 402, the blocking block 404 blocks the blocking frame 402 and prevents the cylindrical tooth 401 from continuing to rotate. First, the resistance is continuously increased to increase the force required for the rotation to slow down the moving speed of the patient, and then it is blocked to avoid moving The sudden jam during the process restricts the patient's movement, which causes the hip joint to be suddenly restricted and suffer secondary injuries.

The above is only a preferred embodiment of the present invention, but the design concept of the present invention is not limited thereto.
