Surgical staples having compressible or crushable members for securing tissue therein and stapling instruments for deploying the same

摘要

A staple (1350) having a crown (1302), a deformable leg (1344) extending from the crown, and a spring (1352) extending from the crown configured to compress tissue between the spring and the deformable member. Owing to the flexibility of the spring, the staple can accommodate a wide range of tissue thicknesses while still compressing the tissue captured therein. As a result, a single staple design can be used in a wide variety of surgical procedures thereby reducing the amount of staple designs that must be provided to the surgeon. In at least one embodiment, the staple includes a crushable member. This crushable member can include a plastically deformable first portion and an elastically deformable second portion.
