Embodiment Construction

[0023] The present invention will be described in detail below in conjunction with examples. It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. For the convenience of description, if the words "up", "down", "left" and "right" appear in the following, it only means that the directions of up, down, left and right are consistent with the drawings themselves, and do not limit the structure.

[0024] Such as figure 1 with figure 2 As shown, the fixation device for avulsion fractures of the tibial insertion of the anterior cruciate ligament includes a fixation plate 1 and four fixation wires 2 slidably fixed in the fixation plate, and the two ends of the fixation wires 2 are viewed from opposite directions respectively. Protrude out of the fixed plate.

[0025] The fixing plate has 4 protruding parts 4, each protruding part is arranged parallel to each other, and there...

Abstract

The invention relates to a fixing device for avulsion fractures of the anterior cruciate ligament (ACL) tibial insertion. The fixing device comprises a fixing plate and multiple fixed lines slidably fixed in the fixing plate. Two ends of each fixed line respectively extend out of the fixing plate from opposite directions. The whole device has a simple structure. The fixing plate and the fixed lines can slide relative to each other. In the implantation process, the position of the fixing plate can be conveniently adjusted. The operation is simple and convenient and facilitates fracture reduction and pressed fixation of the ACL tibial insertion during an operation, thus shortening the time for reduction and fixation surgery of fractures and simplifying the operation. The contact area betweenthe fixing plate and a fracture block is large, and the fixation is firm. No secondary surgery is required to remove a fixture, which reduces operative wounds and improves the quality of the operation. The device of the invention is applicable to various types of avulsion fractures of ACL tibial insertion.

Description

technical field [0001] The invention relates to a fixation device for anterior cruciate ligament tibial insertion avulsion fracture, and belongs to the field of medical instruments. Background technique [0002] With the increasing number of sports injuries and traffic trauma, the incidence of avulsion fractures of the tibial insertion of the anterior cruciate ligament is on the rise. Anterior cruciate ligament tibial insertion avulsion fracture is an intra-articular fracture, because it is the attachment point of the anterior cruciate ligament on the tibia, so the displacement of the tibial insertion of the anterior cruciate ligament avulsion fracture is likely to cause loss of function of the anterior cruciate ligament. Seriously affect the function of the knee joint, improper treatment will cause varying degrees of disability, and cause a lot of inconvenience to the normal life of the patient. Type I fractures generally advocate conservative treatment with plaster bandag...
