Surgical equipment capable of achieving vertical traction, separation and reduction of tibia of knee joint and femur and knee joint surgical equipment

Abstract

The invention provides a surgical device for separating and reducing the vertical traction of the tibia and femur at the knee joint, which belongs to the field of medical equipment and includes a fixing device and a base. The fixing device includes a first support frame and a second support frame. The first support frame It is vertically arranged with the second support frame, the joint between the first support frame and the second support frame is connected to the base in rotation, and the axis of rotation of the fixing device relative to the base is perpendicular to the plane where the first support frame and the second support frame are located. The surgical device for separating and reducing the vertical traction of the tibia and femur at the knee joint provided by the present invention aims to accurately, quickly and conveniently separate and reset the tibia and femur at the knee joint without invasive vertical traction when the human body is in the anterior or lateral position. The vertical setting of the first support frame and the second support frame can make the knee joint appear in a 90-degree vertical state, so that the knee joint is exposed, and the end of the femur and the tibial plateau do not interfere with each other during the operation.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a surgical device for separating and reducing the vertical traction of the tibia and femur at the knee joint and the knee joint surgical device. Background technique [0002] The technique of traction and reduction of joints around the tibia, femur, and knee joint has been successfully applied. It is a new technology for the treatment of tibial fractures, femur fractures, knee joint fractures, or knee joint replacement. The quality of life is more popular in developed countries. [0003] The inventor found in the research that the current traction reduction surgery has at least the following disadvantages: 1. The existing traction equipment needs to invasively fix the joints, which will cause secondary damage to the human body; Interference between the end of the femur and the tibial plateau is not conducive to surgery. Contents of the invention [0004] The purpose of the pres...
