Manifold for gas enhanced surgical instruments
First Claim
1. A surgical instrument assembly comprising:
- a surgical instrument including a housing having a fluid flow tube, the fluid flow tube having a discharge port defined at a distal end of the housing;
an actuator assembly having an actuator that controls the flow of fluid through the fluid flow tube; and
a manifold operably coupled to the housing and configured for operable engagement with at least a first source of pressurized gas and one or more sources of fluid, the at least first source of pressurized gas and one or more sources of fluid being arranged such that releasing the pressurized gas from the source of pressurized gas draws one or more fluids from the one or more sources of fluid.

Abstract
There is disclosed a fluid supply manifold for use with various surgical instruments, such as, electrosurgical instruments. The fluid supply manifold includes two or more connection ports for receipt of sources of fluid supply by either bulk sources or sources contained within canisters. The manifold may include a mixing chamber for mixing the various sources of fluids within the manifold or may include flow tubes for providing the sources of fluid directly to the surgical instrument to be mixed within the surgical instrument. Control valves are associated with each of the connection ports to control the flow of fluids through the manifold. The manifold may also include a gas inlet to facilitate drawing the fluids out of the various sources as well as mixing the fluids within the manifold.

9. A gas enhanced electrosurgical instrument assembly comprising:
-
an electrosurgical instrument having a fluid flow tube, the fluid flow tube having a discharge port defined at a distal end of the surgical instrument; a generator that provides a source of energy to the electrosurgical instrument; a manifold configured for operable engagement with at least a first source of pressurized gas and one or more sources of fluids, the at least first source of pressurized gas and one or more sources of fluid being arranged such that releasing the pressurized gas from the source of pressurized gas draws one or more fluids from the one or more sources of fluid; and an actuator assembly having an actuator that controls the source of energy provided by the generator and the flow of fluids from the manifold to the fluid flow tube of the electrosurgical instrument, wherein the manifold is operably coupled to the actuator assembly.
