Abstract

The invention provides a tie gun for sternum suture. The tie gun comprises a shell, a brake wrench and a handle; when the tie gun is in use, a tie penetrating through a lock catch extends into the shell through a tie moving groove, the handle is held by a hand, and then the brake wrench is wrenched to be driven to move towards the direction of the handle in an opening of the shell, at the moment,a transverse plate of the brake wrench is driven to move towards the direction of the handle, and a first spring is compressed; the purposes that a torsion spring drives a toothed plate to rotate, thetoothed plate is meshed with teeth on the tie, and the tie is driven to be tensioned and locked can be achieved; then the tail part of the tie is cut off by using cutting pliers, so that suture and fixation of thoracic surgery is realized; the toothed plate is a ratchet, and the tie gun is simple in structure, convenient to operate, small in size and light in weight, the labor intensity of clinicians can be effectively relieved, operation time can be shortened, and the effect of saving time and labor can be achieved.

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...
