AI Technical Summary

Technical Problem

Existing linear surgical staplers have difficulty achieving effective sealing and cutting simultaneously when clamping and cutting tissue, and the staple formation is not ideal, affecting the surgical outcome.

Method used

A linear surgical stapler was designed, comprising a cartridge half and an anvil half, which, through the synergy of a clamping lever and a firing assembly, can cut and drive staples through tissue while clamping it, while utilizing a three-dimensionally shaped staple cartridge and staple driver to ensure effective staple shaping and tissue sealing.

Benefits of technology

It achieves effective sealing and cutting of tissue, improves surgical outcomes, enhances the hemostatic ability and compression force distribution of the staples, reduces the user's operating force, and improves the efficiency and quality of surgery.

Abstract

This invention discloses a staple cartridge configured for use with a surgical stapler. The staple cartridge includes a cartridge body, a platform defined for compressing tissue against an anvil of the surgical stapler, and a plurality of staple openings formed in the platform. A plurality of staples are disposed within the staple openings, each staple having a pair of legs. A plurality of staple actuators are also disposed within the staple openings, the staple actuators being actuable to drive the staple through the tissue and against the anvil to shape the legs. Each staple actuator includes an actuator body, a first recess on a first lateral side of the actuator body, and a second recess on a second lateral side of the actuator body. The first and second recesses are configured to receive the legs of the corresponding staple as they are shaped against the anvil.
