CN209450580U and CN 109330813a both relate to a lower limb fixing device for knee joint replacement surgery, which adjusts the extension or flexion of the knee joint by sliding the foot, but the structure is complicated, the number of components involved therein is large, the knee joint replacement surgery is aseptic surgery, all components need to be disassembled for aseptic disinfection when the device is used, the workload is large, a serious person may be difficult to realize complete disinfection and disinfection, secondly, all components need to be assembled when the device is used for surgery, the work is complicated, the time and energy of medical workers are consumed, the device is not beneficial to the surgery, and the practicability is very poor.
SUMMERY OF THE UTILITY MODEL
The utility model discloses a solve the weak point among the prior art, provide a knee joint replacement is limbs fixing device for art, this fixing device simple structure, disinfection and sterilization and its equipment are convenient, save medical staff's time, make things convenient for the operation to use, and the practicality is high.
In order to solve the technical problem, the utility model adopts the following technical scheme: the limb fixing device for knee joint replacement comprises a foot support and a bottom plate, wherein a row of oblique insertion holes are formed in the upper surface of the bottom plate, the included angles between the row of oblique insertion holes and the horizontal forward direction are sequentially increased from back to front, and the included angle between each oblique insertion hole and the horizontal forward direction is an obtuse angle;
the foot supports and holds in palm including sole layer board and achilles tendon layer board, the tip fixed connection and the two mutually perpendicular of sole layer board and achilles tendon layer board, and sole layer board and achilles tendon layer board both sides limit are fixed with the curb plate, are fixed with the card post on the sole layer board, and the card post is located the extending direction of achilles tendon layer board, is connected with the elastic webbing on one of them curb plate, and the tip of elastic webbing passes through the magic and pastes the connection on another curb plate.
The bottom surface of the bottom plate is provided with a rubber layer.
The upper surface of the achilles tendon supporting plate is provided with a sponge cushion layer.
Adopt above-mentioned technical scheme, the utility model discloses following beneficial effect has: the utility model changes the positions of the foot supports on different oblique insertion holes to meet the requirement of adjusting the flexion or extension angle of the knee joint in the operation process, compared with the complicated mechanical structure in the comparison document, the utility model has simple structure, can meet the flexion and extension angle of the knee joint, is convenient for the whole disinfection and sterilization, lightens the workload of medical staff and saves time; the angle that knee joint bucking or extended can be changed through the position of adjustment foot support at different oblique jacks, convenient to use, compare with the comparison file, the practicality is strong, more is applicable to present knee joint replacement operation.
