Abstract

The invention relates to a device for fixing avulsion fracture of anterior cruciate ligament tibia insertion. The device comprises a flexible mesh sheet body and two first fixing lines which are slidably connected to the mesh sheet body. One end of the first fixing line protrudes to one side of the mesh sheet body, and the other end of the first fixing line extendes from the other side of the meshsheet body; a plurality of pairs of the second fixing lines A and the second fixing lines B are disposed between the adjacent first fixing lines, and one end of the second fixing line A is fixed on the first side of the mesh sheet body, one end of the second fixing line B is fixed to the second side of the mesh sheet body, and the first side and the second side are opposite and both are located between the adjacent first fixing lines. The device has the advantages of simple structure, convenient insertion, and simple operation, shortens operation time of fracture reduction and fixation, simplifies operation and fixes firmly, is suitable for various types of avulsion fractures of the anterior cruciate ligament tibia insertion, and is easy to manufacture, and the material is cheap, which greatly reduces the cost and reduces the burden of medical expenses.

Description

technical field [0001] The invention relates to a device for fixing an avulsion fracture of anterior cruciate ligament tibial insertion, which belongs to the field of medical instruments. Background technique [0002] Avulsion fracture of tibial insertion of anterior cruciate ligament is an avulsion injury of tibial insertion of anterior cruciate ligament caused by trauma, which belongs to intra-articular fracture. Because the fracture part is the attachment point of the anterior cruciate ligament on the tibia, the displacement of the avulsion fracture of the tibial insertion of the anterior cruciate ligament will easily lead to the loss of function of the anterior cruciate ligament and the displacement of the fracture, which will seriously affect the function of the knee joint. Improper treatment will cause different The degree of disability causes a lot of inconvenience to the normal life of patients. [0003] Meyers and Zariczny et al. divided the tibial avulsion fractur...
