Sternum median incision connector

Abstract

The invention discloses a sternum median incision connector, which comprises a left surrounding arm and a right surrounding arm which are matched with each other. The matching end of the left surrounding arm and the right surrounding arm is provided with a locking mechanism, the locking position of which can be transversely adjusted. A bent transverse pressurizing part is arranged on the left surrounding arm and / or the right surrounding arm. The invention has the advantages that the stability and the firmness are high, the fixing strength is strong, the function of continuous pressurization is obtained, the bone healing is facilitated, the freedom of the sternum during longitudinal movement is not limited because the contact area between the connector and the longitudinal part of the sternum is small, and patients do not feel uncomfortable; the surgical procedure is simple and convenient and the connector can be taken out conveniently because the left surrounding arm and the right surrounding arm can be separated through releasing the locking mechanism only and can be respectively taken out.

Description

technical field [0001] The present invention relates to a sternotomy connector for use after a median sternotomy. Background technique [0002] During thoracic surgery, due to the need for patient treatment, sometimes the sternum is cut along the midline to open the chest. After the operation, the two halves of the sternum are connected together. Traditionally, several methods are used to close the sternum to ensure the stability of the sternum and the rehabilitation of the patient, such as Mersilene fibers, steel wires, metal and plastic straps, Nitinol clips, etc. [0003] The most common method currently used is to connect the two halves of the sternum with a wire wrapped around the sternum and passed through the intercostal space. However, due to the tension of lung respiration, it is difficult to control the binding strength of the steel wire. If the tying is too loose, the fixation effect will not be achieved; if the tying is too tight, the steel wire will easily bre...

AI Technical Summary

Problems solved by technology

However, due to the tension of lung respiration, it is difficult to control the binding strength of the steel wire

If it is tied too loosely, it will not be able to fix it; if it is too tight, it will easily break the steel wire, which may damage the vital organs under the sternum, leading to medical accidents

Therefore, the traditional sternal suture method has certain risks, and the fixation effect is not good, and the steel wire is not easy to remove after the sternum heals

Although the sternal bone plate disclosed in the patent No. 200520078272.X solves the problem of binding sternal fixation, its contact area with the sternum is too large, which limits the freedom of longitudinal movement of the sternum, and makes people feel uncomfortable
