FIELD: medical equipment.
SUBSTANCE: group of inventions relates to a surgical stapling instrument. Device for a surgical stapler comprises a reinforcing member, an adhesive material and a retaining sheet. Reinforcing element has dimensions allowing to install it on the support or platform of the cartridge with staples of the surgical stapling instrument. Adhesive material is located on the reinforcing element. Adhesive material is configured to flow through the reinforcing member in response to a temperature higher than the melting point. Retaining sheet is arranged on adhesive material. Retaining sheet is attached to the reinforcing member so that the retaining sheet is configured to hold the adhesive material on the reinforcing member. In a second embodiment, the surgical stapler comprises a reinforcing member, a fluid adhesive material and a retention sheet. Reinforcing element has dimensions allowing to install it on the support or platform of the cartridge with staples of the surgical stapling instrument. Fluid adhesive material is placed on the reinforcing element. Fluid adhesive material is configured to flow through the reinforcing member in response to a temperature higher than the melting point. Retaining sheet is arranged on fluid adhesive material. Retaining sheet is attached to reinforcing element so that retaining sheet is configured to retain fluid adhesive material on reinforcing element. In the third version, the device for a surgical stapling instrument comprises a cassette, a fluid adhesive material and a retaining sheet. Cassette forms a recess the size of which makes it possible to receive the support or platform of the cassette with staples of the surgical stapling instrument. Cassette includes a platform located in the recess. Fluid adhesive material is located on the platform. Retaining sheet is attached to cassette. Retaining sheet has such dimensions and location to retain fluid adhesive material on platform.
EFFECT: use of inventions makes it possible to reduce risk of tissue rupture in area of applied staples or near it.
