The invention provides a self-locking intramedullary nail device for proximal fibula fracture. The device comprises: a main nail which comprises a main nail proximal segment and a main nail distal segment, wherein one end of the main nail proximal segment is connected with the main nail distal segment, the other end of the main nail proximal segment is of a cylindrical structure, and a cylindricalhollow groove is formed in the cylindrical structure; a self-locking deformation device arranged in the columnar hollow groove in a penetrating manner; a self-locking forcing screw, wherein a clamping groove is formed in the right side end of the screw head end of the self-locking forcing screw; a matched screwdriver, wherein one end, close to the columnar hollow groove, of the matched screwdriver is connected with one end of a tail sleeve, the other end of the tail sleeve is connected with the inner wall of the columnar hollow groove through threads, an axial screw rod is installed in the matched screwdriver, and the end, close to the self-locking forcing screw, of the axial screw rod is connected with the self-locking forcing screw through a clamping groove. Through self-locking fixation, the situation of iatrogenic injury of the nervus peroneus communis caused by poor position of the interlocking nail is reduced.
Description
technical field [0001] The invention relates to the technical field of medical instruments, in particular to a self-locking intramedullary nail device for proximal fibula fractures. Background technique [0002] The proximal fibula is an important part of the knee joint. As a non-main load-bearing bone, the fibula bears about 1 / 6 of the load of the knee joint. Therefore, the traditional view holds that fractures of the proximal fibula do not need to be fixed. [0003] However, recent studies have shown that the posterolateral structure of the knee joint is mainly composed of the upper joint structure of the tibia and fibula and a series of ligament tissue structures. Although the fibula is not the main weight-bearing bone, it is an important part of its structure. The main structures involved are: the fibula Head (supporting the posterolateral structure of the tibial plateau); lateral collateral ligament (one end attached to the proximal end of the fibula, composed of the be...
