Endoscopic stapler and adapter used for endoscopic stapler

Abstract

The invention relates to an adapter used for an endoscopic stapler. The adapter includes a striking push rod, a nail bin connection rod, a nail bin lock rod, an elastic element, an outer sleeve pipe and a blocking element; the surface of the striking push rod is provided with a groove, the nail bin connection rod is provided with a first limiting hole matched with the groove, the nail bin lock rodis provided with a limiting part, and the elastic element is used for making the nail bin lock rod be abutted to a boss of the tail end of the nail bin component; when the striking push rod is located at a starting position, and the blocking element falls in a groove of the striking push rod and is located on the lower side of the limiting part; when the striking push rod leaves from the startingposition, and the blocking element moves into the first limiting hole of the nail bin connection rod under the effects of the side wall of the groove and the side wall of the first limiting hole andis abutted to the rear side face of the limiting part. According to the adapter used for the endoscopic stapler, when the striking push rod moves forward from the starting position, the blocking element is located in the first limiting hole and abutted to the rear side face of the limiting part, the nail bin lock rod can not move backward, so that the nail bin component can not accidentally fall off and the smoothness of an operation is ensured.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to an adapter for a laparoscopic stapler and a laparoscopic 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 staple cartridge assembly at a specific position near the lesion, perform resection, and suture at the same time. [0003] The laparoscopic stapler includes a staple cartridge assembly, an adapter and a handle, wherein the staple cartridge assembly is detachably mounted on the adapter. In order to avoid wasting time, a structure that allows the staple cartridge assembly to be quickly installed and disassembled is adopted. Specifically, the tail end of the cartridge assembly is inserted a certain distance from the front end of the adapter and then...
