Abstract

Claims (13)

1. An end effector of a surgical stapler, comprising:

first and second jaw members, the first jaw member movable relative to the second jaw member, the first jaw member including a first projection and a second projection distal of the first projection; and

a buttress including a buttress material and first and second bands configured to engage the first and second projections, respectively, the buttress material and at least one of the first or second bands formed of separate components such that portions of the separate components are axially spaced apart to define an axial gap therebetween, the at least one of the first or second bands having opposing end portions extending axially along a length of the buttress material in a superposed relation with the buttress material, wherein at least one of the first or second bands is formed of an elastic material such that the at least one of the first or second bands is in tension along a longitudinal axis of the buttress when the first and second bands engage the respective first and second projections.

2. The end effector according to claim 1 , wherein the buttress is transitionable between an unexpanded state and an expanded state.

3. The end effector according to claim 2 , wherein a first distance is defined between the first and second bands in the unexpanded state, and a second distance is defined between the first and second projections, the first distance being shorter than the second distance.

4. The end effector according to claim 1 , wherein at least one of the first or second projections includes an hourglass profile.

5. The end effector according to claim 1 , wherein the first jaw member includes an anvil.

6. The end effector according to claim 5 , wherein the second jaw member includes a staple cartridge.

7. The end effector according to claim 1 , wherein the at least one of the first or second bands has a first elasticity and the buttress material has a second elasticity different from the first elasticity.

8. An end effector of a surgical stapler comprising:

first and second jaw members, the first jaw member movable relative to the second jaw member, the first jaw member including a first projection and a second projection distal of the first projection; and

a buttress including a buttress material and first and second bands configured to engage the respective first and second projections, the buttress material and at least one of the first or second bands formed of separate components such that portions of the separate components are axially spaced apart to define an axial gap therebetween, the at least one of the first or second bands having opposing end portions extending axially along a length of the buttress material in a superposed relation with the buttress material, wherein the first and second bands are formed of an elastic material such that the first and second bands are extendable along a longitudinal axis defined by the buttress when the first and second bands engage the respective first and second projections.

9. The end effector according to claim 8 , wherein the first and second bands are disposed in respective opposing ends of the buttress.
