Tibia distraction, traction, reduction and supporting system

Abstract

The invention discloses a tibia distraction, traction, reduction and supporting system. The tibia distraction, traction, reduction and supporting system comprises a base and a tibia distraction devicemounted on the base; the tibia distraction device comprises a tibia distraction portion and a foot positioning portion mounted at the front end of the tibia distraction portion; the tibia distractionportion comprises a front supporting plate, a distraction device and a rear supporting plate which are successively connected from front to back; and the distraction device can be connected with thefront supporting plate and the rear supporting plate in a mode of twisting around a long axis, and the distance between the front supporting plate and the rear supporting plate is adjusted via the distraction device. The tibia distraction, traction, reduction and supporting system is used for supporting and traction on the lower rear side of tibia, an incision and an operative approach under a supine position are avoided, thus, a doctor can select the operative approach favorably, meanwhile, the tibia is effectively supported from rear to front, the tibia distraction portion can be twisted toimplement dissection and reduction on fracture, the series of actions are finished under occlusion, bleeding is avoided, and when a fracture position reaches a position preset by the doctor, the surgery can be carried out easily.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a tibial distraction reduction support system. Background technique [0002] The tibia is one of the two bones of the lower leg. It is located on the inner side of the lower leg and plays an important role in supporting body weight. It is the main load-bearing bone in the lower leg. Patients with tibial fractures generally require tibial surgery to perform traction and reduction of the affected limb. Now hospitals basically use traction tools and instruments, such as fixed traction pins. The working principle is to use two bone traction pins to respectively fix near the articular surface of the distal and proximal segments of the fracture, and then squeeze the movable block in one direction by rotating the middle nut. It achieves the effect of traction, but it cannot be used for patients with osteoporosis. Because it is point-fixed, the stability of reset is poor, and th...

AI Technical Summary

Problems solved by technology

If you want to adjust the traction in a sterile state, because the area of ​​the traction frame is a sterile area, the operator can only rely on other personnel in the audience to complete the desired position by the operator. This work is time-consuming and laborious. Because it is necessary to frequently interrupt the operation or train of thought to direct the assistant

The bigger problem is that the fracture surgery on the tibial side basically cannot use this traction frame, because the ankle joint is in a bacterial state
