Sternum plate occlusion apparatus

Abstract

The invention relates to an occlusion apparatus for opening and occluding sternum plates. The occlusion apparatus is characterized in that two screw seats are arranged on a screw, the screw penetratesthe screw seats, and the screw seats are fixed onto slide rods by the aid of dowels; rotary wheels are arranged at two ends of the screw and are fixed onto the screw by the aid of pins; the screw isprovided with left and right right-hand and left-hand double-start threads, a left arm and a right arm are distributed at two edges of the screw, first threaded holes are formed in the left arm and the right arm, slide rails are arranged on the left arm and the right arm, the first threaded holes and the screw are in threaded transmission with one another, the slide rails and the slide rods are inslide fit with one another, and the left arm and the right arm can move in a reciprocating manner by the aid of the slide rods when the screw clockwise and anticlockwise rotates, so that the left armand the right arm can be quickly separated from each other or can be quickly drawn in. The occlusion apparatus has the advantages that the left arm and the right arm can be separated from each otheror can be drawn in by the aid of movement principles of the right-hand and left-hand double-start threads of the screw, and accordingly the sternum plates can be quickly separated from one another orcan be quickly drawn in by the aid of double-start threads.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a closer, which is used to expand and close a sternal plate. Background technique [0002] After the traditional thoracotomy in cardiothoracic surgery, the sternum needs to be closed and fixed. Usually, the sternum plate is placed on both sides of the sternal fissure, and special surgical reduction forceps are used to clamp the center of the sternum plate to close the sternum. After the sternum heals, it is necessary to For disassembly, use special surgical reduction forceps to separate the sternal plates and remove the fixed sternal plates; however, the existing special surgical reduction forceps are complicated to operate, and the speed of separating or closing the sternal plates is relatively slow, which increases the risk of surgery. Contents of the invention [0003] In view of the above-mentioned defects of the prior art, the purpose of the present invention is to provide a...
