Surgical apparatus and structure for applying sprayable wound treatment material
First Claim
1. An apparatus for forming an anastomosis between adjacent sections of tissue, comprising:
- a body portion;
an actuation assembly operatively supported at a proximal end of the body portion;
an anvil assembly movably mounted at a 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 assembly toward and away from the 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, wherein the dispersion assembly includes;
a manifold having a plurality of ejection ports for dispensing wound treatment material, the channel directing the wound treatment material across the ejection ports, wherein the ejection ports include;
a plurality of first ejection ports formed therein for dispensing a first wound treatment material; and
a plurality of second ejection ports formed therein for dispensing a second wound treatment material different from the first wound treatment material;
wherein the plurality of first ejection ports and the plurality of second ejection ports are both provided on opposed sides of the manifold; and
wherein the plurality of first ejection ports and the plurality of second ejection ports are radially oriented; and
at least one conduit for conducting wound treatment material to the dispersion assembly.

18. A circular surgical stapling apparatus, comprising:
-
a tubular body portion having an actuator; a staple pusher member operatively disposed at a distal end of the tubular body portion and being operatively connected to the actuator for expelling an annular array of staples from the tubular body portion; an anvil assembly movably mounted at the distal end of the tubular body portion for movement toward and away from the tubular body portion; an approximation assembly extending between the tubular body portion and the anvil assembly for moving the anvil assembly toward and away from the tubular body portion; a nozzle operatively associated with the approximation assembly, the nozzle including at least one ejection port disposed between the anvil assembly and the tubular body portion and being configured to dispense at least one fluid, wherein the nozzle includes a manifold having; a plurality of first ejection ports formed therein for dispensing a first wound treatment material; and a plurality of second ejection ports formed therein for dispensing a second wound treatment material different from the first wound treatment material; wherein the plurality of first ejection ports and the plurality of second ejection ports are both provided on opposed sides of the manifold; wherein the plurality of first ejection Ports and the plurality of second ejection ports are radially oriented; and at least one conduit for conducting wound treatment material to the nozzle. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34)
