Embodiment 1

[0042] see Figure 1-10 , the present invention provides a technical solution:

[0043] A leg positioning mechanism for orthopedic surgeons, including a control module 32, the positioning mechanism includes a fixing module for supporting and fixing;

[0044] The fixing module includes two fixing frames 2 arranged on the front and rear sides. The two fixing frames 2 can move closer to the middle so as to fit and fix the hip bones on the left and right sides of the patient 1. The inner side of the fixing frame 2 is provided with an arc-shaped part 2b , the arc-shaped portion 2b can match the surface skin of the waist of the patient 1, increase the fitting effect between the fixed frame 2 and the patient, and play a role in increasing the fixing effect. The inner side of the fixed frame 2 is provided with an inclined portion 2a, and the inclined portion 2a Under the blocking effect of the hip bone, it can play a role of support and fixation, and further play a role in increasing...

Embodiment 2

[0049] see Figure 1-10 , the present invention provides a technical solution:

[0050] A leg positioning mechanism for orthopedic surgeons, including a control module 32, the positioning mechanism includes an identification module for training effect analysis and training speed analysis;

[0051] The training module includes a foot fixing module 7, a first turning point 9 and a second turning point 13. The bottom end of the foot fixing module 7 is provided with a roller, and the roller is used to reduce the resistance when the calf slides. The foot fixing module 7. After fixing the foot of the patient 1, the first connecting rod 8 can drive the lower leg to perform knee-bending activities, and the second rotation point 13 can be set at the hip joint, which can ensure the rotation of the second connecting rod 11. Move up and down, the first pivot point 9 can be set at the knee joint, and it can ensure the up and down movement of the first connecting rod 8. A first link is arr...

Embodiment 3

[0057] see Figure 1-10 , the present invention provides a technical solution:

[0058] In this embodiment, the same parts as those in Implementation 2 will not be repeated, and the difference lies in the following;

[0059] By adopting the above-mentioned technical solution: when the thigh is raised, the first drawstring 4 does not engage with the connecting block 6, and the engaging component 15 and the movable component 16 lock the second rotation point 13. At this time, the lifting angle of the thigh Being fixed, the patient 1 can freely realize the movement of the knee joint through the movement of the calf muscles, and realize the active training of the knee joint. At the same time, if the driving module 3 works, the pull rope 4 can pull the first connecting rod 11 Drive the calf to move up and down. In this environment, you can also perform forward deep knee movement to increase the angular range of motion of the calf and realize the second type of training;

Abstract

A leg positioning mechanism for orthopedists comprises a control module, a fixing module used for supporting and fixing, an identification module used for training effect analysis and training speed analysis, and a training module used for knee bending and positioning. The fixing module comprises two fixing frames arranged on the front side and the rear side, the two fixing frames can draw close to the middle to be attached to and fixed to the left hip bone and the right hip bone of the patient, arc-shaped parts are arranged on the inner sides of the fixing frames and can be matched with the surface skin of the waist of the patient, and the attaching effect of the fixing frames and the patient is improved; the left side of the bottom end of the fixing frame is rotatably connected with a fixing part which plays a role in increasing the fixing effect, the inner side of the fixing frame is provided with an inclined part, the inclined part can play a role in supporting and fixing under the blocking effect of the hip bone and further plays a role in increasing the fixing effect, and the left side of the bottom end of the fixing frame is rotatably connected with a pressing plate which is arranged in an L shape.

Description

technical field [0001] The invention relates to the technical field of leg positioning, in particular to a leg positioning mechanism for orthopedic surgeons and a method for using the same. Background technique [0002] Total or partial knee replacement surgery is called knee arthroplasty. A total or partial knee replacement may be done to relieve knee pain, for example, from arthritis. Although there are many types of arthritis, most knee pain is caused by three types: osteoarthritis, rheumatoid arthritis, and traumatic arthritis, among others. A prosthetic knee implant is used to repair and / or replace damaged bone and muscle in the body. [0003] After the knee prosthesis is implanted, it is necessary to go through later training to meet the adaptation to the prosthesis and restore the normal work of the knee joint. In the rehabilitation training of the knee joint, there is an action to flatten the leg and lower the knee joint. Press to make the leg bend, bend towards t...
