Problems solved by technology

The third unsatisfactory part of this style of endoscopic surgical stapler is that the abnormal situation that the nail cartridge assembly and the nail anvil assembly in the executive assembly are stuck occurs, which only occurs once every 100 times on average, so the United States The effective use efficiency of the complex operating components of the endoscopic surgical stapler introduced in the patent US20100133318A1 is too low

Abstract

The present invention discloses an opening and closing control mechanism of an endoscopic surgical stapler. The opening and closing control mechanism of the endoscopic surgical stapler is characterized by being provided with a deflector rod, and a groove formed in a front part of a stapler body close to a percussion handle. A used technical scheme is that when the opening and closing control mechanism controls a nail bin assembly and a nail anvil assembly in an execution assembly to execute an opening action, the operation can be finished by only using one finger to rotate the deflector rod and using the other finger to hook the groove of the stapler body in a single-hand manner; and a used technical scheme is that when the opening and closing control mechanism controls the nail bin assembly and the nail anvil assembly in the execution assembly to exit from actions of stapling and cutting, only one finger of a hand holding the stapler body is needed to hook the groove of the stapler body, and a reset button drives a driving rod to move backwards in the stapler body. Thus the opening and closing control mechanism achieves technical effects of preventing the endoscopic surgical stapler from swinging, also avoiding misoperation of the percussion handle and also shortening surgical time.

Description

technical field [0001] The present invention relates to the opening and closing operation mechanism of the endoscopic surgical stapler used in the endoscopic surgical operation, particularly relates to the opening and closing operation mechanism of the laparoscopic surgical stapler, and also particularly relates to the opening and closing operation mechanism of the thoracoscopic surgical stapler Close the control mechanism. Background technique [0002] In laparoscopic surgery and thoracoscopic surgery, a variety of endoscopic surgical staplers are usually used for cutting and Anastomosis surgery is also used in cutting and anastomosis operations such as lungs and trachea in the respiratory tract, and bladder and uterus in the genitourinary system, which can reduce surgical trauma, shorten operation time, and improve operation quality. Various laparoscopic surgical staplers can also be used in various open operations. [0003] The endoscopic surgical stapler introduced in ...
