CASSETTE WITH FASTENERS HAVING SLIDE STARTING ELEMENT Russian patent published in 2019 - IPC A61B17/72 

FIELD: medicine.

SUBSTANCE: group of inventions relates to medical equipment, specifically to surgical cutting and fastening instruments, which are configured to cut and fasten tissues, staple cartridges therefor and surgical staples for use therewith. Fastener assembly for use with a surgical instrument comprises a cartridge body including a platform, sockets for fasteners, fasteners and slides. Each fastening element is at least partially arranged inside the seat for fasteners. Sleds are made with possibility to push fasteners from fasteners seats. Slides comprise a first slope and a second slope. First slope is made with possibility to lift fasteners from first position to partially lifted position. Second slope is made with possibility to lift fasteners from partially raised position to ejected position. First slope can move relative to the second slope. Slides can displace between proximal non-activated position, intermediate partially activated position and distal activated position during inrush stroke. First slope is at least partially folded inside the second slope when the slides are in the proximal non-activated position, and the first slope is extended relative to the second inclination when the slides are in the intermediate partially activated position. In a second embodiment, the fastener assembly for use with the surgical instrument comprises a support, wherein fastener cartridge assembly comprises cassette housing including platform, sockets for fasteners, fasteners and firing element. Each fastening element is at least partially arranged inside the seat for fasteners. Firing member is configured to move the fasteners to the anvil. Firing element comprises a first slope and a second slope. First slope is made with possibility to lift fasteners to thrust. Second slope is made with possibility to lift fasteners to thrust. First slope can move relative to the second slope. Firing assembly is movable between a proximal inactive position, an intermediate partially activated position and a distal activated position during the firing stroke. First slope is at least partially folded inside the second slope when the firing element is in the proximal non-activated position and the first slope is extended relative to the second slope when the firing member is in an intermediate partially activated position. First slope is at least partially folded inside the second slope when the firing element is in the distal activated position.

EFFECT: use of inventions makes it possible to reduce or eliminate haemorrhage from soft tissues.
