Surgical Apparatus Including Surgical Buttress
First Claim
1. A surgical stapling apparatus, comprising:
- a housing;
an end effector being secured to the housing and having first and second jaw assemblies, the first jaw assembly defining a plurality of fastener retaining slots, the second jaw assembly defining a plurality of fastener forming pockets, at least one of the first and second jaw assemblies defining a plurality of recesses formed in a tissue contacting surface thereof;
a plurality of fasteners disposed in the fastener retaining slots of the first jaw assembly and configured and dimensioned to be formed by the fastener forming pockets of the second jaw assembly; and
at least one surgical buttress having a body including a plurality of plugs extending therefrom, the plugs being integrally formed with the body and being relatively positioned on the body for insertion into the plurality of recesses to secure the at least one surgical buttress to at least one of the first jaw assembly and the second jaw assembly, the body configured and dimensioned to substantially overlie at least one of;
at least some of the fastener retaining slots of the first jaw assembly; and
at least some of the fastener forming pockets of the second jaw assembly.

Abstract
A surgical stapling apparatus includes a housing, an end effector, fasteners, and one or more surgical buttresses. The end effector is secured to the housing and has first and second jaw assemblies. The first jaw assembly defines slots and the second jaw assembly defines pockets. One or both of the first and second jaw assemblies define recesses. The fasteners are disposed in the slots of the first jaw assembly and are formed by the pockets of the second jaw assembly. The one or more surgical buttresses have a body that includes plugs that are integrally formed with the body for insertion into the recesses to secure the surgical buttress(es) to one or both of the first and second jaw assemblies. The body substantially overlies at least some of the slots of the first jaw assembly and/or at least some of the pockets of the second jaw assembly.

18. A method of mounting a surgical buttress to an end effector for a surgical stapling apparatus, the method comprising the steps of:
-
providing an end effector for a surgical stapling apparatus, the end effector including a first jaw assembly defining a plurality of fastener retaining slots and a second jaw assembly defining a plurality of fastener forming pockets, at least one of the first and second jaw assemblies defining a plurality of recesses; providing a surgical buttress formed of a first material; providing a second material on the surgical buttress at predetermined locations on the surgical buttress; placing the surgical buttress against a tissue contacting surface of one of the first jaw assembly and the second jaw assembly; exposing the surgical buttress to heat and pressure to move the second material into the plurality of recesses; and removing the heat and pressure to interlock the second material within the plurality of recesses to secure the surgical buttress on at least one of the first jaw assembly and the second jaw assembly. - View Dependent Claims (19)
