Abstract
An apparatus includes a stapling assembly and an anvil. The stapling assembly includes first and second staples. Each of the first and second staples include first legs. The anvil together with the stapling assembly is configured to clamp tissue of a patient. The anvil includes a first staple forming pocket that is configured to transition the first legs of the first and second staples from a non-deformed state to a deformed state with the same firing stroke.
Claims20
An apparatus comprising:
- (a) a stapling assembly that includes first and second discrete staples spaced apart in non-contact relation, wherein each of the first and second discrete staples includes a first leg and a second leg;
- and
- (b) an anvil that together with the stapling assembly is configured to clamp tissue of a patient, the anvil comprising:
- (i) a first staple forming pocket configured to sequentially transition the first legs of the first and second discrete staples from a non-deformed state to a deformed state with the same firing stroke, and
- (ii) a second staple forming pocket configured to transition the second legs of the first and second discrete staples from a non-deformed state to a deformed state with the same firing stroke.

An apparatus comprising:
- (a) a stapling assembly that includes first and second discrete staples spaced apart in non-contact relation, wherein each of the first and second discrete staples includes a crown, a first leg, and a second leg, wherein the crown defines a length, wherein the length of the crown and the first leg of the first discrete staple extend along a first plane, wherein the length of the crown and the second leg of the first discrete staple extend along a second plane that is parallel to and offset from the first plane in a non-deformed state and a deformed state;
- and
- (b) an anvil that together with the stapling assembly is configured to clamp tissue of a patient, wherein the anvil includes a first staple forming pocket that is configured to transition at least the first legs of the first and second discrete staples from the non-deformed state to the deformed state with the same firing stroke.
An apparatus comprising:
- (a) a stapling assembly comprising:
- (i) first and second discrete staples spaced apart in non-contact relation, wherein each of the first and second discrete staples includes first and second legs,
- (ii) an elongate knife slot, and
- (iii) first and second staple cavities configured to receive the respective first and second discrete staples, wherein the first and second staple cavities are obliquely oriented relative to the elongate knife slot so as to angle the first and second legs of the first and second discrete staples in a three-dimensional orientation in a deformed state;
- and
- (b) an anvil that together with the stapling assembly is configured to clamp tissue of a patient, wherein the anvil includes a first staple forming pocket that is configured to sequentially transition the first legs of the first and second discrete staples from a non-deformed state to the deformed state with the same firing stroke.
