Abstract

The invention provides an endoluminal cutting stapler assembly capable of preventing tissue slippage, comprising a staple abutment plate, a staple cartridge and a plurality of staples. The root of thestaple abutment plate is rotatably connected with the root of the staple cartridge. The staples are installed in the staple cartridge, and the staple cartridge is provided with a clamping surface forclamping tissue. one end of the cartridge facing the attending physician is defined as the proximal end of the cartridge, the distal end of the cartridge is distal to the attending physician's cartridge, the clamping surface is provided with a cutter groove which runs from the proximal end of the nail cartridge to the distal end of the nail cartridge. The cutter groove is provided with a plurality of nail outlet holes for sewing nails. The longitudinal direction of the cutter groove is taken as the direction of the cutter groove. The clamping surface is transversely provided with an anti-skidrib at a position close to each nail outlet hole. The invention can effectively prevent the tissue from slipping in the assembly when the tissue is clamped and cut, and ensures the effective suture and cutting separation of the sutured tissue.

Description

technical field [0001] The invention relates to the field of intracavity linear cutting staplers, in particular to an intracavity cutting stapler assembly for preventing tissue slippage, which is suitable for surgical suturing of digestive tract. Background technique [0002] The endoluminal cutting stapler assembly is a minimally invasive surgical instrument for digestive tract surgery. The endocavity cutting stapler includes a protective sleeve, an anvil plate, a cutting knife, a staple cartridge, and multiple staples. The anvil plate and the staple cartridge are connected to one end of the protective sleeve, and the anvil plate and the staple cartridge are rotatably connected. Both the staples and the cutting knife are installed in the staple cartridge. During the working process, the intracavitary cutting stapler needs to effectively clamp and fix the sutured physiological tissue under reasonable extrusion, so as to ensure that the staples in the product can effectively...
