A surgical kit for sternal closure and fixation

Abstract

The invention discloses a surgical kit for sternal closing and fixation, which includes a sternal closing fixator, and an installation tool and a disassembly tool for respectively installing and disassembling the sternal closing fixator; the sternal closing fixator includes a locking wheel, Male and female fasteners. The male fixation part and the female fixation part of the sternum closing fixator of the present invention are fixed through the meshing of the first helical teeth and the second helical teeth. When installed, the meshing of the helical teeth is stable and reliable; when dismantling, the disassembly tool is used to reduce the male fixing part and the female fixing part. The distance between the fixed part and the female fixed part, at this time, the first helical tooth can be squeezed by the second helical tooth, so that the meshing state between the first helical tooth and the second helical tooth is released, so that the sternum can be effectively removed Fixator to avoid difficulty in removing the sternum closure fixator due to plastic deformation of the male fixator.

Description

technical field [0001] The invention relates to a surgical kit for sternal closure and fixation. Background technique [0002] Thoracotomy requires an incision of the entire sternum. At the end of the operation, the traditional method of closing the sternum is to bind the entire sternum up and down with steel wires. Tighten it so that the incised sternum is closed and fixed. There are following deficiencies in the traditional steel wire fixing sternum method: 1, it is difficult to grasp and unify the tightness of fixing. 2. Cutting of the sternum by the steel wire is easy to occur, resulting in splitting of the sternum and bringing adverse consequences. 3. It is difficult to wear steel wire. [0003] Based on this, the sternal closure fixer is gradually favored by more and more doctors. The current sternal closure fixation device has a male fixing part and a female fixing part. A locking groove is arranged on the male fixing part, and a rotatable locking wheel is arrange...

AI Technical Summary

Problems solved by technology

There are following deficiencies in the traditional steel wire fixation method for sternum: 1. It is difficult to grasp the tightness of fixation and unify

2. It is easy to cut the sternum by the steel wire, which will cause the sternum to crack and bring adverse consequences

3. It is difficult to wear steel wire

However, in practical application, it is found that because the sternum heals takes a long time, it may cause plastic deformation of the male fixation piece, and finally lead to the situation that the sternal closure fixation is difficult to remove
