Description

Angle adjustable bending pliers

technical field

The utility model relates to the technical field of instruments for laparoscopic operation, in particular to an angle-adjustable bending forceps.

Background technique

In thoracoscopic surgery, the function of curved forceps is very important. Indispensable when bluntly dissecting important vessels. Through the curvature of the curved forceps, the dorsal part of the blood vessel can be mobilized (in laparoscopic operation, this is almost the only way to mobilize, because the field of view and angle are limited). In dorsal mobilization, the direction of the blood vessels that need to be mobilized is different from that of the endoscope. Therefore, bending pliers with different curvatures are required. In some cases, even individual customization is required.

Chinese patent application: The Chinese utility model patent with the patent publication number CN201775661U and the publication date of 2011.03.30 discloses a multifunctional bendable surgical forceps for laparoscopic surgery. It is designed with non-destructive clamping teeth and arc-shaped grooves that match up and down. The body of the forceps has the function of electrocoagulation and hemostasis.
