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 surgical equipment capable of achieving vertical traction, separation and reduction of the tibia of a knee joint and the femur, and belongs to the field of medical instruments.The surgical equipment comprises a fixing device and a base, wherein the fixing device comprises a first supporting frame and a second supporting frame, the first supporting frame and the second supporting frame are vertically arranged, and the connection portion of the first supporting frame and the second supporting frame is rotationally connected with the base; the axis line, rotating relativeto the base, of the fixing device is perpendicular to the plane where the first supporting frame and the second supporting frame are located. The surgical equipment capable of achieving vertical traction, separation and reduction of the tibia of the knee joint and the femur aims to achieves precise, quick, convenient and noninvasive vertical traction, separation and reduction of the tibia of the knee joint and the femur when the human body is in the normal position or the side position, the first supporting frame and the second supporting frame are vertically arranged to make the knee joint ina 90-degree vertical state, and the knee joint is exposed; in addition, the tail end of the femur and the tibial plateau do not interfere with each other in the operation process.

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...
