CURVED TERMINAL WORKING BODY FOR STAPLER Russian patent published in 2018 - IPC A61B17/72 

FIELD: medicine.

SUBSTANCE: group of inventions includes a staple cartridge and an end working body of the surgical stapler, relates to the field of medical machinery and is intended for use in surgery. The staple cartridge includes a casing containing a plate, a plurality of first and second cavities for staples, a plurality of drive devices, a warped longitudinal passage and a compressible tissue thickness compensator. The plurality of first cavities for staples is arranged along the first curve. The said first curve is defined by the first radius of curvature, and each said first staple cavity comprises an opening in the said plate. The plurality of second cavities for staples is arranged along the second curve. The said second curve is defined by the second radius of curvature. This first radius of curvature is different from the second radius of curvature. Each said second staple cavity comprises an opening in the said plate. The plurality of staple drive devices is arranged within the said first staple cavities and the said second staple cavities. Each staple drive device is arranged to move between an inoperative position and an actuation position. The warped longitudinal passage is designed to accommodate the drive device for staple drive devices lifting between these inoperative position and actuation positions. The plurality of staples is arranged in the plurality of first staple cavities and in the plurality of second staple cavities where the staples are supported by staple drive devices. Each staple comprises a base and at least one leg protruding from the base. The staple legs are configured so that they protrude beyond the plate when the staple rive devices are in the inoperative position. The compressible tissue thickness compensator is located above the said plate, and the staple legs extend into the tissue thickness compensator.

EFFECT: inventions allow to expand the arsenal of technical means for this purpose.
