Surgical apparatus and structure for applying sprayable wound treatment material
First Claim
1. A surgical stapling apparatus, comprising:
- a body portion including a proximal end and a distal end, the body portion supporting an actuating handle member at the proximal end thereof and a staple pusher member at the distal end thereof;
an anvil assembly removably mounted at the distal end of the body portion, the anvil assembly being movable toward and away from the body portion;
an approximation assembly extending between and operatively connected to the body portion and the anvil assembly, wherein the approximation assembly moves the anvil assembly toward and away from the body portion, the approximation assembly including a shaft configured for releasable connection with the anvil assembly; and
a wound treatment material dispersion assembly operatively associated with the approximation assembly, the dispersion assembly including;
at least one fluid source,at least one conduit in fluid communication with the at least one fluid source and extending into the shaft of the approximation assembly; and
at least one ejection port formed in the shaft of the approximation assembly and being in fluid communication with the at least one conduit wherein the at least one ejection port is configured to dispense fluid from the at least one fluid source to a location between the staple pusher member and the anvil assembly,wherein the approximation assembly includes a nozzle supported on the shaft, wherein the nozzle of the approximation assembly includes a manifold having a plurality of ejection ports, wherein the plurality of ejection ports include;
a plurality of first ejection ports for dispensing a first wound treatment material; and
a plurality of second ejection ports for dispensing a second wound treatment material different from the first wound treatment material, andwherein the wound treatment dispersion assembly includes a cap operatively connected to the manifold, and wherein the cap defines a channel between an inner surface of the cap and an outer surface of the manifold.

Abstract
According to an aspect of the present disclosure, an apparatus for forming an anastomosis between adjacent sections of tissue is provided. The apparatus includes a body portion; an actuation assembly operatively supported at a proximal end of the body portion; an anvil assembly movably mounted at the distal end of the body portion for movement toward and away from the body portion; an approximation assembly extending between the body portion and the anvil assembly for moving the anvil toward and away from the tubular body portion; a dispersion assembly operatively associated with the approximation assembly, the dispersion assembly including at least one angled surface defining at least one channel interposed between the anvil assembly and the body portion and being configured to dispense a fluid therefrom; and at least one conduit for conducting wound treatment material to the dispersion assembly.
