Abstract

The invention provides a laparoscopic stapler, which is used to solve the problems in the prior art that the cutting knife will not be reset after being pushed out, there is a safety hazard, and the safety structure of the cutting knife affects the structural strength of the base of the nail box and has a complex structure. Including: cutting knife mechanism, nail magazine assembly, nail magazine base, nail abutment seat assembly, safety assembly and nail magazine rear general assembly; push-pull part, the output end of the push-pull part is used to push and pull the cutting knife, and the output of the push-pull part The end is fixed with a second hook; the nail cartridge assembly is detachably installed on the nail magazine base; when the nail cartridge assembly is taken out from the nail magazine base, the safety component will hinder the forward movement of the push-pull member, and the When the nail cartridge assembly is installed on the nail cartridge base, the nail cartridge assembly overcomes the resistance of the safety assembly and releases the restriction on the forward and backward displacement of the push-pull member. It has a safety function, and the cutting knife can be hidden automatically.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a endoscopic stapler. Background technology [0002] Kehui version of endoscopic stapler consists of body and nail box. Usually, in one operation, a gun body will fire multiple nail boxes, and the cost of each nail box is relatively high, which causes a heavy medical burden to patients. [0003] In order to reduce the medical burden of patients, many manufacturers at home and abroad have launched nail boxes with replaceable nail bin, that is, most of the body of the nail box can be used multiple times in the same operation. However, in the existing products, the cutting knife assembly, nail box and nail bin are designed separately, that is, most of the body of the cutting knife assembly and nail box can be used multiple times in the same operation. However, with the increase of cutting times, the cutting edge of the cutting knife will become more and more blunt and the safety mechanis...
