FIELD: medicine.

SUBSTANCE: group of inventions relates to medical equipment, specifically to surgical staplers. Fastener cartridge for use with a surgical suturing instrument comprises a cartridge body, a projection, a cavity for fasteners and a fastener. Cartridge body includes a platform configured to support tissue. Ledge extends from platform, wherein projection comprises conical slot. Cavity for fasteners is made in a platform. Cavity for fasteners has the first end of the cavity and the second end of the cavity. First end of the cavity has the first lateral wall and the second side wall. First side wall and second side wall converge at one point. Fastening element is arranged with the possibility of release into the cavity for fasteners. Fastening element comprises base, first leg and second leg. First leg extends from the base. First leg is releasably arranged at first end of said cavity. First side wall and the second side wall are configured to hold the first leg at a distance from convergence of the side walls at one point such that between the sidewalls converging at one point and the first leg there is a gap. Second leg extends from the base. Second leg is releasably arranged at the second end of the cavity. In the second version, the fastener cartridge for use with a surgical suturing instrument comprises a cartridge body, a projection, a cavity for fasteners and a fastener. Cavity for fasteners contains the first end of the cavity, the second end of the cavity and the wedge. Fastening element comprises base, first leg and second leg. First leg extends from the base. First leg is releasably disposed relative to the first end of the cavity. Wedge is configured to hold the first leg at a distance from the first end of the cavity so that there is a gap between the first end of the cavity and the first leg. Second leg extends from the base. Second leg is releasably arranged relative to the second end of the cavity. In the third version, the fastener cartridge for use with the surgical suturing instrument comprises a cartridge body, a projection, a cavity for fasteners and a fastener. Cavity for fasteners is made in a platform. Cavity for fasteners comprises a longitudinal slot including the first end of the cavity and the second end of the cavity. Fastening element is arranged with the possibility of release into the cavity for fasteners. Fastening element comprises a base, a first leg extending from the base, a second leg extending from the base, a first biasing means for displacing the first leg from the first end of the cavity and a second biasing means for displacing the second leg from the second end of the cavity.

EFFECT: invention enables tissue fixation.
