Abstract

The invention relates to a safety switch. The safety switch is characterized in that the safety switch comprises a main body, a limit part, a trigger part and a proximity switch, wherein the main bodyis movably disposed in a housing of an endoscopic stapler and is provided with a limit unit, the limit part is fixedly arranged in the housing of the endoscopic stapler and provided with a first limit slot and a second limit slot which match with the limit unit, the trigger part is arranged on the main body, and the proximity switch is fixedly disposed on the housing of the endoscopic stapler; the limit unit can switch between the first limit slot and the second limit slot; when the limit unit switches from the first limit slot to the second limit slot, the trigger part triggers the proximityswitch to transmit signals to a control unit of the endoscopic stapler. Only when the proximity switch is triggered can the safety switch be opened, and only when the proximity switch transmits the signals to the control unit can the endoscopic stapler be started to operate, or the endoscopic stapler is not to be started. Consequently, double protection is provided to prevent the false start of the endoscopic stapler.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a safety switch and an endoscopic stapler. Background technique [0002] At present, minimally invasive surgery occupies an important position in surgery. Laparoscopic stapler is a commonly used surgical instrument in minimally invasive surgery. The working principle of the laparoscopic stapler is to clamp the lesion by the staple cartridge assembly, perform resection, and suture the lesion while resecting. [0003] However, during the operation, due to emergency and other reasons, medical staff may mistakenly touch the switch of the endoscopic stapler, resulting in false activation of the endoscopic stapler. Contents of the invention [0004] Based on this, it is necessary to provide a safety switch that can effectively prevent the false start of the endoscopic stapler for the problem of false start of the endoscopic stapler. [0005] A safety switch comprising: [0006]...
