Embodiment Construction

[0039] The present invention will be described in detail below in conjunction with specific embodiments. The following examples will help those skilled in the art to further understand the present invention, but do not limit the present invention in any form. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all belong to the protection scope of the present invention.

[0040] Such as figure 1 As shown, according to the present invention, a kind of anterior cruciate ligament attachment avulsion fracture puncture and fixation wire passing device includes a wire passing tube 1; the inside wall of the head of the wire passing tube 1 is provided with a wire clamping groove 102; the wire clamping groove 102 Extend along the axial or tangential direction of the line pipe 1 . Preferably, the front edge 101 of the head end of the wire-passing pipe is a blunt mouth. The tange...

Abstract

The invention provides an anterior cruciate ligament attachment avulsion fracture puncturing and fixing thread guider which comprises a thread guide tube (1). A thread clamping groove (102) is formed in the head tube wall of the thread guide tube (1) and extends in the axial direction of the thread guide tube (1). A blunt opening is formed in the head end face front edge (101) of the thread guide tube (1). Compared with the prior art, the anterior cruciate ligament attachment avulsion fracture puncturing and fixing thread guider has the advantages of being reasonable in structure, capable of achieving multi-angle selection, convenient to use and capable of achieving puncture without hurting tissue.

Description

technical field [0001] The invention relates to a thread passer, in particular to a thread passer for puncturing and fixing anterior cruciate ligament avulsion fracture. Background technique [0002] The avulsion fracture of the tibial plateau attachment to the anterior cruciate ligament (ACL) of the knee joint has a special location, which is located in the joint cavity. Anterior cruciate ligament attachment fractures often lead to ACL relaxation, joint instability, and subjective symptoms of pain and limited mobility. If not treated in time, the joint will appear flexion contracture, seriously affecting the function of the knee joint. This type of fracture is more common in children and adolescents. In recent years, due to the development and popularization of national fitness campaigns, the prevalence rate of adults has also shown an increasing trend year by year. [0003] For ACL tibial plateau avulsion fractures, if the clinical imaging examination shows that the displ...
