Layer arrangements for surgical staple cartridges

Abstract

A piece of buttress material and an end-effector of a surgical instrument including features which can aid a surgeon in properly and quickly attaching the piece of buttress material to the end-effector. In various embodiments, a piece of buttress material can include retention features which can be engaged with portions of an end-effector to releasably retain the piece of buttress material to at least a portion of the end-effector. Similarly, an end-effector can include features configured to engage portions of a piece of buttress material to releasably retain the piece of buttress material to the end-effector. In at least one embodiment, more than one piece of buttress material can be releasably retained to an end-effector.

AI Technical Summary

Benefits of technology

The invention relates to a washable surgical stapling instrument that can be used to repair tissues and organs. The instrument includes a staple cartridge and an anvil, which can be connected together using staples. A piece of buttress material is used to reinforce the staple line. The buttress material can be attached to the instrument using an unactivated adhesive, allowing for easy positioning and alignment by the surgeon. The adhesive can then be activated to securely bond the buttress material to the instrument. The buttress material can also have a recess or perforation to allow for easy removal after the staples are deployed. The technical effects of this invention are improved staple line reinforcement and reduced bleeding and leaks during surgery.

Problems solved by technology

In some circumstances, the layers of tissue can be relatively thin, can have a high fluid content, and / or can have a non-uniform thickness, which can cause the staples to be improperly formed within the tissue.

In various embodiments, a piece of buttress material can be difficult for a surgeon to attach to the jaw members of an end-effector.

As a result, the surgeon can spend valuable time positioning and aligning a piece of buttress material on a jaw member of an end-effector.
