Abstract

The invention discloses a surgical instrument with a stepless lock mechanism. The surgical instrument comprises a far-end working head, a near-end handle and a lengthened rod extending in the near-endhandle. The handle comprises a front handle body, a rear handle body and a handle rotating shaft. The handle rotating shaft is connected with the front handle body and the rear handle body. The fronthandle body and the rear handle body can rotate relative to the handle rotating shaft. The working head comprises a pair of tong heads and a driving mechanism connected with the tong heads. The lengthened rod comprises a rotating wheel, an outer rod and an inner pull rod. The outer rod and the rotating wheel are fixed to each other and are mounted in the front handle body. One end of the inner pull rod is connected with the driving mechanism, and the other end of the inner pull rod is connected with the rear handle. The handle further comprises the lock mechanism with an effective mode and anineffective mode.

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...
