Buttress material with alignment and retention features for use with surgical end effectors

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.

Description

BACKGROUND[0001]i. Field of the Invention[0002]The present invention generally relates to buttress material for a surgical instrument, and to buttress material configured to be releasably attached to an end-effector assembly of a surgical instrument.[0003]ii. Description of the Related Art[0004]A surgical instrument, such as a surgical stapler, for example, can be configured to deploy staples into tissue during a surgical procedure. In various embodiments, the surgical stapler can include an end-effector configured to be positioned on a distal end of the surgical stapler. The end-effector can be configured to be positioned within, and slid at least partially through, a cannula, or trocar, positioned in a wall of a patient's body such that a surgeon can utilize the end-effector to perform work within a surgical site. In various embodiments, the end-effector can comprise a first jaw member including a staple cartridge and, additionally, a second jaw member including an anvil. The firs...

Benefits of technology

[0012]In at least one form of the invention, a piece of buttress material configured to be releasably attached to an end-effector can include an unactivated adhesive. In various embodiments, a surgeon can position and align the piece of buttress material on the end-effector multiple times without the un-activated adhesive bonding to the end-effector. Once the surgeon is satisfied with the alignment of the piece of buttress material on the end-effector, the surgeon can then apply a reactant to the un-activated adhesive. In various embodiments, the reactant can activate the adhesive and cause the adhesive to releasably bond the piece of buttress material to a portion of the end-effector. In at least one embodiment, the piece of buttress material can include a recess configured to receive an applicator such that the application of the reactant to the un-activated adhesive can be fa...

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 p...
