Abstract

The invention provides a punching device which comprises a first forceps arm, a second forceps arm, a punching needle and a first through hole. The connection structure is used for movably connecting the first forceps arm and the second forceps arm which are arranged in a crossed mode, dividing the first forceps arm into a first operation section and a first working section, and dividing the second forceps arm into a second operation section opposite to the first operation section, and a second working section opposite to the first working section. The punching needle is arranged on the first working section and comprises a threading hole or threading groove used for threading. The first through hole is formed in the second working section and opposite to the punching needle, and can allow the punching needle to penetrate through. According to the punching device, the threading hole or threading groove used for threading is formed in the punching needle; before punching, a thread or steel wire can penetrate into the threading hole or threading groove; after punching is finished, the punching needle passes through together with the thread; threading is completed during punching; compared with a traditional punching device, threading holes do not need to be found after punching any more, threading is easy, and the 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 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. At present, a Kirschner wire is used to drill the hole. It is difficult to find 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 split fractures of the posterior edge of the greater trochanter, increasing the difficulty of the operation, and adding pain to the patient.
