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) a body portion and an approximation shaft associated with the body portion;
(b) an anvil assembly movably mounted at a distal end of the body portion for movement toward and away from the body portion;
(c) a system operatively associated with the approximation shaft, the system 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 system includes;
(i) a plurality of ejection ports for dispensing wound treatment material in a radial direction;
(ii) a conduit communicating with the channel for dispensing a gas; and
(iii) at least one second conduit for conducting wound treatment material to the plurality of ejection ports.

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.

11. An apparatus for forming an anastomosis between adjacent sections of tissue, comprising:
-
(a) a body portion and an approximation shaft including a trocar, the trocar being configured to selectively engage a stem of an anvil assembly; (b) an anvil assembly mountable to the approximation shaft for movement toward and away from the body portion; (c) a dispersion assembly operatively associated with the trocar of the approximation shaft; (i) the dispersion assembly including at least one angled surface on the trocar, wherein the dispersion assembly includes; a plurality of ejection ports for dispensing wound treatment material defined in a surface of the trocar and being directed toward the at least one angled surface; the plurality of first ejection ports being oriented in a radial direction; and at least one source of wound treatment material to the dispersion assembly. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
