STAPLE CARTRIDGE ASSEMBLY COMPRISING STAPLE CAVITIES FOR PROVIDING BETTER STAPLE DIRECTION Russian patent published in 2020 - IPC A61B17/72 

FIELD: medical equipment.

SUBSTANCE: group of inventions relates to surgical stapling and cutting tools and cassettes with staples intended for use with them. Staple cartridge assembly for use with a surgical stapling instrument comprises a cartridge body. Cartridge body includes a proximal end, a distal end, a platform, a longitudinal slot and a staple cavity. Longitudinal slot is formed in the platform passing from the proximal end to the distal end. Staple cavity comprises an upper opening, a lower opening, a proximal guide, a distal guide, a side wall, an intermediate guide, a bracket, a proximal end of the cavity and a distal end of the cavity. Lateral wall passes between the proximal guide and the distal guide. Intermediate guide passes inside from side wall. Bracket is stored with possibility of removal in staple cavity. Bracket comprises a proximal pedicle, a distal pedicle and a base. Proximal end of the cavity is proximal to the proximal guide. Distal end of the cavity is distal to the distal guide. Between the base of the bracket, the intermediate guide and the distal end of the cavity there is a first gap. Between the base of the bracket, the intermediate guide and the proximal end of the cavity there is a second gap. In the second version, the staple cartridge assembly for use with the surgical suturing instrument comprises a cassette body. Cartridge body includes a proximal end, a distal end, a platform, a longitudinal slot and a staple cavity. Staple cavity comprises an upper opening, a lower opening, a proximal guide, a distal guide, a side wall, an intermediate guide, a bracket. Bracket comprises a proximal pedicle, a distal pedicle and a base. Proximal leg and a distal leg form a foot plane. Proximal leg and distal leg are pressed to each other by a proximal guide and a distal guide. In the third version, the staple cartridge assembly for use with a surgical suturing instrument comprises a cassette body. Cartridge body includes a proximal end, a distal end, a platform, a longitudinal slot and a staple cavity. Staple cavity comprises an upper opening, a lower opening, a proximal guide, a distal guide, a side wall, an intermediate guide and a bracket. Bracket comprises a proximal pedicle, a distal pedicle and a base. Proximal guide, the distal guide and the intermediate guide provide triple control of the bracket when the bracket is removed from the staple cavity. Between the base, intermediate guide and distal guide there is a first gap. Between the base, intermediate guide and proximal guide there is a second gap.

EFFECT: use of inventions enables tissue dissection and suturing.
