Abstract

The present disclosure relates to surgical instruments, structures and methods for enhancing the properties of tissue to be repaired or joined. According to an aspect of the present disclosure, a surgical stapling apparatus is provided including a wound treatment material dispersion system for delivering wound treatment material to a target surgical site. The dispersion system includes an aperture formed in the anvil assembly oriented to dispense wound treatment material in an outward direction; and a source of wound treatment material in fluid communication with the aperture of the anvil assembly.

Claims

1. A surgical stapling apparatus, comprising:

a staple pusher assembly being operative to expel an array of staples therefrom upon actuation of the surgical apparatus;

an anvil assembly having an anvil disposed in juxtaposed relation to the staple pusher assembly and being configured to form the array of staples expelled from the staple pusher assembly upon actuation of the surgical stapling apparatus, the anvil assembly having a stem positioning the anvil relative to the staple pusher assembly, the stem defining a longitudinal axis;

an approximation assembly extending between the staple pusher assembly and the anvil assembly for moving the anvil assembly toward and away from the staple pusher assembly toward the staple pusher assembly; and

a wound treatment material dispersion system for delivering a wound treatment material to a target surgical site, the wound treatment material dispersion system being disposed at least one of;

about the stem of the anvil assembly; and

about the anvil assembly and the staple pusher assembly;

the wound treatment material dispersion system including;

at least one aperture formed in the anvil assembly and being oriented to dispense wound treatment material in a radially outward direction relative to the longitudinal axis; and

a source of wound treatment material in fluid communication with the at least one aperture formed in the anvil assembly, wherein the wound treatment material is at least one of an adhesive, a sealant, a hemostat, and a medicament.

2. The surgical stapling apparatus according to claim 1, further comprising:

a body portion;

an actuation assembly operatively supported at a proximal end of the body portion, wherein the staple pusher assembly is operatively disposed at a distal end of the body portion and being operatively connected to the actuation assembly for expelling the annular array of staples; and

an approximation assembly extending between the body portion and the anvil assembly for moving the anvil toward and away from the staple pusher assembly.

3. The surgical stapling apparatus according to claim 2, further comprising an annular blade retractably disposed at a distal end of the body portion, wherein the annular blade includes a plurality of openings formed therein.

4. The surgical stapling apparatus according to claim 1, wherein the dispersion system includes a nozzle supported on a surface of the anvil of the anvil assembly that is disposed opposite to the staple pusher assembly, and wherein the at least one aperture formed in the anvil assembly is provided in the nozzle.

5. The surgical stapling apparatus according to claim 4, wherein the dispersion system includes a lumen extending through a stem of the anvil assembly which is in fluid communication with the at least one aperture formed in the nozzle.

6. The surgical stapling apparatus according to claim 5, wherein the lumen of the stem of the anvil assembly is fluid communicatable with the source of wound treatment material.

7. The surgical stapling apparatus according to claim 6, wherein the surgical stapling apparatus is configured and adapted to dispense wound treatment material onto the target surgical site at least one of before, during and after firing of the surgical stapling apparatus.

8. The surgical stapling apparatus according to claim 1, wherein the at least one aperture is formed in the stem of the anvil assembly.

9. The surgical stapling apparatus according to claim 8, wherein the dispersion system includes a lumen extending through a stem of the anvil assembly which is in fluid communication with the at least one aperture formed therein.

10. The surgical stapling apparatus according to claim 9, wherein the lumen of the stem of the anvil assembly is fluid communicatable with the source of wound treatment material.

11. The surgical stapling apparatus according to claim 10, wherein the surgical stapling apparatus is configured and adapted to dispense wound treatment material onto the target surgical site at least one of before, during and after firing of the surgical stapling apparatus.

12. The surgical stapling apparatus according to claim 8, wherein the stem of the anvil assembly includes an annular groove formed proximally and distally of the at least one aperture.
