Abstract

The invention provides a cable tie gun for sternum suture, which includes: a housing, a brake wrench and a handle. When in use, the cable tie passing through the lock buckle is inserted into the inside of the housing through a cable tie movable groove, and the cable tie gun is held by hand. handle, and then by pulling the brake wrench, the brake wrench moves toward the handle in the opening of the housing, and at this time, the horizontal plate of the brake wrench is brought to move toward the handle , and make the first spring be compressed; it can realize that the torsion spring rotates with the tooth plate, and makes the teeth on the tooth plate and the cable tie mesh with each other, and carries the cable tie The purpose of tightening and locking; then use the cutters to cut off the tail of the cable tie to realize the suturing and fixing of the chest operation; the tooth plate provided by the present invention is a ratchet, the structure is simple and easy to operate, and the cable tie gun is small in size. The light weight can effectively reduce the labor intensity of clinicians, reduce the operation time, and achieve the effect of saving time and effort.

Description

technical field [0001] The invention relates to the technical field of sternum fixation in cardiothoracic surgery, in particular to a tie gun for sternum suture. Background technique [0002] Most cardiac operations are performed through a median sternotomy. After the operation, the split sternum should be refixed in time. At present, steel wires or other metal wires are often used for binding, tightening and fixing in clinical practice. However, the thin metal wire is easy to break during the fixation process, or cut the sternum, and even cause secondary surgery. [0003] Chinese patent CN206836951U discloses a cable tie for sternum closure, including a cable tie body and a titanium alloy hook. The cable tie body has a keyhole and a groove. The hook tightens and fixes the sternum through the keyhole, and the titanium The material can avoid the allergy phenomenon of the patient, thus reducing the pain of the patient. However, the cable tie needs to be manually tightened wh...
