Abstract

The invention discloses a surgical instrument, comprising a distal working head, a proximal handle and an elongated rod extending therebetween; the handle also includes a lock mechanism, and the lock mechanism includes a valid mode and an invalid mode; the lock The mechanism includes a trigger installed in the front handle, a button and an elastic element; the button interacts with the trigger, drives the trigger to rotate, and realizes the switch between the valid mode and the invalid mode of the lock mechanism; the button includes a first A button and a second button, the first button and the second button are installed on two sides of the front handle respectively.

Description

technical field [0001] The invention relates to a minimally invasive surgical instrument, in particular to a laparoscopic surgical instrument with a locking mechanism. Background technique [0002] Surgical instruments have a history of hundreds of years. During surgery, doctors use different surgical instruments to complete operations such as tissue grasping, cutting, separation, coagulation, and suture closure. Surgical instruments have matured after hundreds of years of development. Laparoscopic surgery has been clinically carried out for more than 30 years and is making rapid progress. Simply put, laparoscopic surgery means that the surgeon uses an extended laparoscopic hand-held instrument to enter the patient's body through the natural orifice or a constructed puncture channel, and completes operations such as tissue grasping, cutting, separation, coagulation, and suture closure. [0003] Compared with traditional open surgery, laparoscopic surgery has the main advant...
