Abstract

The invention provides a nail bin with various nail heights and relates to a nail bin with various nail heights and sizes. The nail bin is used for a surgical operation anastomat and is particularly suitable for being matched with a cavity cutting anastomat, a linear cutting anastomat, a tubular anastomat and a linear anastomat when in use. The nail bin comprises a plane and circular arc-shaped surface combination and organization contact surface or a plane and inclined surface combination and organization contact surface, a suturing nail groove and suturing nails; the suturing nail groove is formed in the plane and circular arc-shaped surface combination and organization contact surface or the plane and inclined surface combination and organization contact surface, and the suturing nails with different heights are installed in the suturing nail groove; the nail bin with various nail heights is provided with a cutting path, nail bin positioning buckles are arranged on the two sides of the nail bin, and a spring clamping piece groove is formed in the near end of the nail bin; the plane and circular arc-shaped surface combination and organization contact surface is set into a plane and convex circular arc-shaped combination and organization contact surface or a plane and concave circular arc-shaped combination and organization contact surface.

Description

technical field [0001] The present invention relates to a staple cartridge with multiple nail heights, which relates to a staple cartridge with various nail heights, which is used for surgical staplers, especially suitable for intracavity cutting staplers, linear cutting staplers, and tubular anastomosis. It is used together with a linear stapler. Background technique [0002] At present, the tissue contact surface of the staple cartridge of the surgical stapler usually adopts multiple stepped tissue contact surfaces or planar tissue contact surfaces of different heights, especially the stepped tissue contact surface is easy to be injured during the surgical clamping and anastomotic cutting process. tissue, causing tissue damage and bleeding, prolonging the operation time, and bringing pain to the patient. Contents of the invention [0003] The purpose of the present invention is to provide a staple cartridge with various nail heights in view of the above disadvantages. I...
