Patella Fixator

Abstract

The invention relates to the technical field of medical instruments, and particularly relates to a patella fixer. The patella fixer comprises a socket member and a plug member; the socket member comprises a socket base, fixing claws and slots, wherein the fixing claws and the slots are fixedly arranged at the two ends of the socket base; socket lock buckles are arranged on two inner sidewalls of the socket base; the plug member comprises a plug base, the fixing claws and plug lock buckles, wherein the fixing claws are fixedly arranged at the two ends of the plug base, and the plug lock buckles are arranged on outer sidewalls of elastic legs; the patella fixer also comprises a strutting mechanism which is convenient for the socket lock buckles and the plug lock buckle to be meshed with each other. The patella fixer provided by the invention is provided with the socket member and the plug member which can be buckled together, and the distance between the socket member and the plug member can be conveniently regulated by insertion and fixation of the socket member and the plug member, so the patella fixer can meet the needs of various different patients, and the fixation effect of the patella fixer on patella is farthest enhanced.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a patella fixator. Background technique [0002] The patella is the largest sesamoid bone in the human body and an important part of the knee joint. It transmits and enhances the strength of the quadriceps and maintains the stability of the knee joint. Patella fracture is a relatively common injury, and improper treatment of patella fracture will seriously affect the function of the knee joint. [0003] Currently clinically use patellar pawls, mostly one-piece structure, realize deformation adjustment by memory alloy, as Chinese patent (CN201001763Y) discloses a butterfly-shaped patellar pawl, the middle part is a pressurizing ring, and there are multiple patellas in the lower part of the pressurizing ring. There is only one lower claw, but its overall size is fixed and cannot be adjusted. When treating and fixing patellas of different sizes, it cannot grasp the pate...
