Abstract

The invention provides an adjustable suture lock catch. The adjustable suture lock catch comprises a fixed base and a lock cylinder detachably connected to the fixed base, wherein a threading channel for threading a suture is formed in the fixed base, and the lock cylinder and the fixed base are relatively fixed or movable so as to lock or release the suture threaded in the threading channel. Therefore, in the suture locking process, the lock cylinder and the fixed base do not deform, the lock catch and the suture are prevented from being damaged, the service life of an instrument is prolonged, and the safety of the instrument is improved; and the length of the suture threaded in the threading channel can be adjusted through movement or fixation between the lock cylinder and the fixed base, so that secondary adjustment is carried out according to real-time conditions.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an adjustable suture lock. Background technique [0002] It is often necessary to knot and fix the suture during the operation. Traditional surgical operations are performed under direct vision of the surgeon, and the knot is usually manually tied by the doctor. However, with the advancement of technology, various minimally invasive operations and interventional operations are becoming more and more common, such as endoscopic surgery, transcatheter interventional surgery, etc. This type of surgery only needs to cut a small operating window on the patient's body, thus reducing Instruments such as endoscopes or interventional catheters are inserted into the patient's body to reach the predetermined site for treatment. In this type of surgery, if the sutures need to be knotted or fixed inside the patient, the operator usually needs to perform remote operation outside the pa...
