Surgical stapler and method
First Claim
1. A surgical stapler comprising:
- a first jaw adapted to receive a staple cartridge in a distal end of the first jaw, the staple cartridge containing a plurality of individual surgical staples, and a working surface with a plurality of staple slots formed therein;
a second jaw having a staple anvil in a distal end of the second jaw, such that during the operation of the surgical stapler the staple cartridge and the staple anvil can be approximated relative to each other;
a driving member for firing the surgical staples from the staple slots and against the approximated staple anvil; and
a tissue cauterizing system operatively associated with the staple cartridge for enhancing one or more properties of adjacent layers of body tissue to be repaired or joined by the surgical stapler, the tissue cauterizing system including a plurality of deployable needles each having a tip, the needles being adapted and disposed in the cartridge such that their tips can be extended out of the working surface of the staple cartridge to penetrate at least a layer of the adjacent layers of body tissue and to deliver electrosurgical energy to the body tissue during at least one of before, after and concomitant with firing of the surgical stapler.

Abstract
The present disclosure relates to surgical instruments including a staple anvil formed in a distal end of the surgical stapler and a staple cartridge selectively receivable in a distal end of the surgical stapler and in juxtaposition relative to the staple anvil, the staple cartridge including one or more laterally spaced apart rows of staple slots formed in an upper surface thereof, a plurality of surgical staples disposed, one each, within the staple slots, and a staple line reinforcing system configured and adapted to augment the strength of the staple line formed by the firing of the surgical staples into body tissue, wherein the surgical stapler concomitantly drives the plurality of surgical staples through the adjacent layers of body tissue to mechanically secure the body tissue and activates the reinforcing system to non-mechanically secure the adjacent layers of body tissue to one another.

11. An electrosurgical system, comprising:
-
a surgical stapler including; a first jaw having a staple cartridge selectively receivable therein, the staple cartridge including; one or more laterally spaced apart rows of staple slots formed in an upper surface thereof; a plurality of surgical staples disposed, one each, within the staple slots; a plurality of staple pushers disposed, one each, within the staple slots in a position to push and eject each of the plurality of staples from the staple slots; and a plurality of deployable needles disposed within the staple cartridge, each of the plurality of deployable needles having a first position wherein the needle is entirely retained within the staple cartridge and a second position wherein a tip portion of the needle projects from the staple cartridge; a second jaw having a staple anvil supported on a distal end thereof; and a driving member operatively associated with the first jaw, the driving member being adapted to be slidingly received within the staple cartridge and to transform a linear displacement thereof into a concomitant transverse displacement of the plurality of staple pushers and of the plurality of deployable needles, the drive member including an energy transmission strip extending longitudinally along the length thereof; and a source of electrical energy electrically connected to the surgical stapler, the source of electrical energy including; a first power line electrically connected to the staple anvil; and a second power line electrically connected to the transmission strip of the drive member and electrically communicable with each of the plurality of deployable needles as the driving member is displaced in a distal direction through the staple cartridge. - View Dependent Claims (12, 13, 14, 15)

16. A surgical stapler, comprising:
-
a first jaw having a staple cartridge containing a plurality of surgical staples, and having a working surface with a plurality of staple slots formed therein; a second jaw having a staple anvil, such that during the operation of the surgical stapler the staple cartridge and the staple anvil can be approximated relative to one another; a driving member for firing the surgical stapler to expel the surgical staples from their staple slots and against the staple anvil; and a body tissue property enhancing system for enhancing one or more properties of body tissue to be repaired or joined by the surgical stapler, the body tissue property enhancing system including; a biocompatible wound closure material dispensing system for dispensing an amount of surgically biocompatible wound closure material to a target staple site during at least one of prior to, after and concomitant with a firing of the surgical stapler to expel the plurality of staples loaded in the staple cartridge, the body tissue property enhancing system comprising at least one reservoir disposed in the surgical stapler and containing the biocompatible wound closure material therein; and at least one member supported by the surgical stapler and being in fluid communication with the at least one reservoir, the at least one member being deployable into the target staple site upon a firing of the surgical stapler and delivering the biocompatible wound closure material to the target staple site. - View Dependent Claims (17, 18, 19, 20)
