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 invention discloses an endoscope surgical stapler capable of being forcibly reset. The endoscope surgical stapler has the technical characteristics that a gear is installed on a stapler body, a rack is arranged on a driving rod, and a wrench is included in accessories equipped by the endoscope surgical stapler. According to the technical scheme, when a staple cartridge assembly and an anvil assembly in an execution assembly are stuck, only one finger of a hand holding the stapler body hooks a groove of the stapler body and inserts the wrench into a driving hole of the gear for rotation, sothat the gear drives the rack to drive the driving rod to move forward and backward in the stapler body. Due to the power amplification effect of the wrench, the technical effects that the staple cartridge assembly and the anvil assembly in the execution assembly can be conveniently controlled the exit anastomosis and cutting actions and executing an opening action, the endoscope surgical stapleris prevented from swinging, and cocking of a handle due mis-operation is avoided are realized.

Description

technical field [0001] The present invention relates to a laparoscopic surgical stapler used in laparoscopic surgery, in particular to a forced reset laparoscopic surgical stapler, and in particular to a forced reset thoracoscopic surgical stapler. Background technique [0002] In laparoscopic surgery and thoracoscopic surgery, various manual endoscopic surgical staplers and electric endoscopic surgical staplers are usually used in the esophagus, stomach, duodenum, small intestine, colon, rectum, Resection and anastomosis of the appendix, gallbladder, pancreas and spleen, etc., are also used in the resection and anastomosis of the lung and trachea in the respiratory tract, and are also used in the resection and anastomosis of the 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 sur...
