Abstract

The invention discloses a posterior cruciate ligament avulsion fracture fixation apparatus and relates to the technical field of medical instruments. The cruciate ligament avulsion fracture fixation apparatus comprises a handle, a long tube, a draw string and a bone reset fixing mechanism; the handle which is of a hollow tubular structure is arranged at one end of the long tube, and the inner cavity of the handle is communicated with the inside of the long tube; the bone reset fixing mechanism is fittingly mounted at the other end of the long tube; one end of the draw string sequentially penetrates the inner cavity of the handle and the inner cavity of the long tube so as to be connected with the bone reset fixing mechanism; the bone reset fixing mechanism comprises a top plate, a short tube and a plurality of fastener strips, the short tube is arranged at one side of the top plate, one end of the short tube is disposed in the long tube, the short tube and the long tube are in threadedconnection, the fastener strips are distributed at one side of the top plate along the outer ring of the short tube, and one ends of the fastener strips are all hinged to the top plate.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a fixation device for posterior cruciate ligament avulsion fractures. Background technique [0002] Posterior cruciate ligament avulsion fracture is a violent injury in the field of sports medicine, commonly seen in car accidents or high-level athletes. The traditional treatment method is to fix the fracture fragments by incision at the back of the knee joint. However, due to the rich distribution of blood vessels and nerves in the back of the knee joint, it is easy to cause damage, which is very difficult in clinical treatment. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a fixation device for posterior cruciate ligament avulsion fracture in view of the above problems. [0004] In order to achieve the above object, the technical scheme of the present invention is as follows: [0005] The posterior cruciate ligament avulsion fra...
