Abstract

The invention discloses a surgical ligaturing instrument and relates to the technical field of medical instruments. The surgical ligaturing instrument comprises an operation handle (1), a disposable inner core (2), a ligature line control handle (3), a knotting control handle (4), a ligature line attachment point (5), a control line attachment point (6) and a ligature loop (7), wherein the operation handle (1) is arranged at one end of the disposable inner core (2), the ligature loop (7) is arranged at the other end of the disposable inner core (2), and the ligature line control handle (3) and the knotting control handle (4) are arranged on the operation handle (1) and are connected with the ligature line attachment point (5) and the control line attachment point (6) on the disposable inner core (2) respectively. The surgical ligaturing instrument has the advantages of reasonable structural design, simplicity in operation, convenience in use, safety, reliability, small foreign matter size, controllability in ligaturing force, less proneness to ligation falling or tissue cutting and capability of meeting use requirements of medical workers.

Description

Technical field: [0001] The invention relates to the technical field of medical instruments, in particular to a surgical ligation instrument. Background technique: [0002] Surgical ligation instruments are used for ligating blood vessels or other tissues in surgical operations, which can be used to ligate blood vessels or tissues quickly and easily. [0003] The traditional ligation method is manual knotting with sutures. The advantages of this method are reliable ligation and less foreign matter. The disadvantage is that the operation is cumbersome and it is difficult to tie knots in narrow spaces, especially in endoscopic surgery. At present, there are mainly two types of ligation devices: titanium metal clips and absorbable material clips. These two ligation devices have the advantages of simple and quick operation, but their disadvantages are that the ligation force is not easy to control, resulting in ligation falling off or tissue cutting, and large foreign objects. ...
