Supporting device for tibial plateau fracture surgery

Abstract

The invention discloses a supporting device for tibial plateau fracture surgery, which comprises a handle rod and a front section bar hinged with the handle rod through a hinge ball, and an angle locking mechanism is arranged on the hinge ball; an extensible supporting plate is arranged at the front end of the front-section rod and is used for unfolding and supporting a bone surface during working; by arranging the extensible supporting plate, the small radial size can be conveniently kept when a surgical incision enters and exits, during working, the radial size can be expanded, a large bone supporting plane is formed, the surgical repair efficiency and the success rate are improved, the handle rod and the front section rod are hinged through the hinge ball, the holding angle of the handle rod is conveniently adjusted, and the surgical operation comfort is improved.

Description

technical field [0001] The invention relates to an orthopedic surgery top support apparatus, in particular to a support device for tibial plateau fracture surgery. Background technique [0002] Tibial plateau fracture is a fracture of the weight-bearing joint. If it is not actively treated, it will lead to uneven knee joint surface, accelerated wear of the joint surface, early knee joint pain, limited movement and other manifestations of osteoarthritis, and no anatomical reduction. Fractures with internal fixation may be malunion or even nonunion; if the fracture fragments are displaced and the articular surface is uneven, and it cannot be reduced by auxiliary means such as traction, open reduction and internal fixation of fractures are generally required. Currently, osteotomy is often used in clinical practice. Approach, expose the collapsed bone fragments, and use tools such as vascular forceps and periosteal dissection tools to reduce the reduction. The disadvantage of th...

[0002] Tibial plateau fracture is a fracture of the load-bearing joint. If it is not actively treated, it will lead to uneven articular surface of the knee joint, accelerate the wear of the articular surface, early knee pain, limited mobility and other manifestations of osteoarthritis, and there is no anatomical reduction. Internally fixed fractures may cause malunion or even fracture nonunion; if the fracture block is displaced, the articular surface is uneven, and cannot be reduced by auxiliary means such as traction, open reduction and internal fixation of the fracture is generally required. Currently, osteotomy is often used clinically The approach is to expose the collapsed bone, and use tools such as vascular forceps and periosteal strippers to perform reduction. The disadvantage of the above scheme is that the surgical wound is large, and if minimally invasive interventional surgery, it is necessary to support the displaced part and knock it However, the radial size of the front end of the existing mandrel is small, making the active area small, making the operation inconvenient and inefficient, and even minimally invasive reduction can not be changed to open reduction surgery
