Description

Ankle joint strutting arrangement is used in operation

Technical Field

The invention relates to the technical field of ankle joint support, in particular to an ankle joint support device for surgery.

Background

The ankle joint is the weight bearing joint of the human body closest to the ground, namely the ankle joint is the joint with the most weight bearing of the whole body. The stability of the ankle joint plays an important role in the normal performance of everyday activities and sports activities, with injuries to the lateral ankle ligaments, including the anterior talofibular and calcaneofibular ligaments being more common. Although the ankle joint eversion sprain is not easy to occur, once the ankle joint eversion sprain occurs, the ankle joint eversion sprain is serious. If fracture occurs, the ankle joint is unstable, and other ligament injuries and fractures are combined at the same time, ankle joint sprain is the most frequent sports injury, accounts for about 40% of all sports injuries, is a common disease in clinic, and is the disease with the highest incidence rate in joint and ligament injuries. Diagnosis of ankle image formation requires the fixation device to fix the ankle so as to obtain a high quality ankle image. The existing fixing device on the market generally fixes a leg supporting part and an operating table, a sole fixing part slides relative to the leg supporting part, and gaps of ankle joints are enlarged.
