Using method of sternum closure assembly

Abstract

The invention discloses a using method of a sternum closure assembly. The method comprises the following steps: measuring the width of sternums and selecting a suitable type of sternum closure fixture; respectively mounting a first fixing member and a second fixing member of the sternum closure fixture on the corresponding left arm and right arm of a sternum closer; pre-closing two sides of the sternums, then separately hooking the first fixing member and the second fixing member onto both sides of the sternums, inserting a rack, and rotating a closing button so as to gradually draw close theleft arm and the right arm of the sternum closer and to further drive the first fixing member to insert into the second fixing member until the sternums are tightly closed without a gap; locking a locking wheel on the first fixing member with a locking member by rotating, and removing the sternum closer; and repeating the above S2-S4 on the upper side and / or lower side of the sternums, and installing 3-4 sternum closure fixtures. The assembly. has the advantages of easy operation, high stability, safety and reliability, and reduces the risk of surgical failure to some extent.

Description

technical field [0001] The invention belongs to the technical field of medical instruments for orthopedic surgery, and in particular relates to a method for using a sternal closure assembly. Background technique [0002] At present, the vast majority of thoracotomy in cardiothoracic surgery at home and abroad adopts the method of longitudinal median incision of the sternum, and the postoperative sternal closure is generally fixed by steel wire binding. The right incised sternum was tightened with a steel wire, so that the incised sternum was closed and then fixed. The traditional method of fixing the sternum with a steel wire has the following disadvantages: 1. It is difficult to grasp and unify the tightness of the fixation; 2. It is easy to cause the cutting of the sternum by the steel wire, resulting in splitting of the sternum and bringing adverse consequences; 3. It is difficult to wear the steel wire. Therefore, it is of great significance to research and develop an a...

Problems solved by technology

The traditional method of fixing the sternum with steel wire has the following disadvantages: 1. It is difficult to grasp and unify the tightness of the fixation; 2. It is easy to cause the steel wire to cut the sternum, causing the sternum to crack and bring adverse consequences; 3. It is difficult to wear the steel wire

[0004] However, in clinical application, it is found that the bones in the first segment of the sternum are often uneven and convex in the middle. If the traditional sternal closure fixer is used at this position, the fixer will not fit tightly with the sternum and the postoperative appearance will be poor. Found obvious problems such as bumps
