Abstract

The invention discloses a nail bin assembly, an anvil assembly, a stapler and an assembly method thereof. The staple cartridge assembly is a replaceable part, which is detachably connected with the fixed block or the staple anvil assembly of the stapler instrument body. The nail anvil assembly with fixed length can cooperate with the nail cartridge assembly with the same or different length to form the actuator of the stapler. The invention can freely replace the staple cartridge assembly according to actual application conditions, which can not only reduce the scattering of staples, but also reduce the cost of consumables required in the operation.

Description

technical field [0001] The invention relates to a medical device, in particular to a staple cartridge assembly, an anvil assembly, a stapler and an assembly method thereof. Background technique [0002] A stapler is a device used in medicine to replace manual suturing. A stapler is generally composed of a staple cartridge, an anvil, a cutting knife, and an instrument gun. The staple bin and the staple anvil are located at the front end of the instrument gun. During the operation, the tissue to be anastomosed is clamped and occluded between the staple cartridge and the anvil, and the handle of the instrument gun is pressed to drive the cutter to cut off the tissue, and at the same time, the staples set in the staple cartridge are pushed out to anastomose the tissue . [0003] The staples are evenly arranged in the staple cartridge, and depending on the total length of the staple arrangement, several staple cartridges with different lengths and specific specifications are g...
