Problems solved by technology

[0005] Therefore, the technical problem to be solved by the present invention is to overcome the technical defect that once the puncher in the prior art is pulled out after punching out the hole, the punched hole will be covered by the surrounding muscle tissue, which makes it difficult to find, and then leads to difficulty in threading. Provide a punching and threading device that does not need to find holes and is easy to thread

Abstract

The invention provides a punching and threading device which comprises a first tong arm, a second tong arm, a connection structure, a punching pin and a first through hole, wherein the connection structure rotatably connects the first tong arm and the second tong arm which are arranged in a cross mode, divides the first tong arm into a first operation segment and a first work segment and divides the second tong arm into a second operation segment opposite to the first operation segment and a second work segment opposite to the first work segment; the punching needle is formed in the first work segment and provided with a threading hole or a thread groove for conducting threading; the first through hole is formed in the second work segment, is opposite to the punching pin and can allow the punching pin to penetrate through therein. According to the punching and threading device, the threading pin is provided with the threading hole or the threading groove for conducting threading, before punching, a wire or a steel wire can be made to penetrate through the threading hole or the threading groove, after punching is completed, the punching pin brings the wire through the threading hole or the threading groove together with the punching pin, threading is conducted while punching is conducted, compared with a traditional punching and threading device, a penetrating hole is not needed to be searched for after punching is conducted, threading is conducted easily, and work efficiency is high.

Description

technical field [0001] The invention relates to the technical field of medical instruments for punching holes, in particular to a punching wire passing device. Background technique [0002] In the posterolateral approach to hip replacement surgery, in order to repair the external rotators and improve the stability after hip replacement, it is necessary to firmly suture the external rotators and the posterior border of the greater trochanter. Therefore, it is necessary to make a hole at the posterior edge of the greater trochanter, pass the suture through the hole, and fix it firmly. Currently, a Kirschner wire is used to drill the hole. It is difficult to find it at the time and increase the operation time; secondly, it is not easy to control the perforation distance of the posterior edge of the greater trochanter, resulting in a split fracture of the posterior edge of the greater trochanter, increasing the difficulty of the operation, and also adding pain to the patient. ...
