Abstract
The invention is directed to an apparatus for providing suction and irrigation to a body site. The apparatus includes a shaft having a distal end for juxtaposition with the body site, and an actuating mechanism operatively configured to facilitate selective actuation of the apparatus to provide either suction or irrigation via the shaft. The shaft has a flow area restriction portion located proximate its distal end.
Claims22
An apparatus for providing suction and irrigation to a body site, the apparatus including
- a shaft having a distal end for juxtaposition with the body site, and
- an actuating mechanism operatively configured to facilitate selective actuation of the apparatus to provide either suction or irrigation via the shaft,
- wherein the shaft has a flow area restriction portion located proximate its distal end.
An apparatus according to any one of the preceding claims, wherein the flow area restriction portion provides a section of constant reduced cross-sectional flow area proximate the distal end of the shaft.
An apparatus according to any one of the preceding claims, wherein the flow area restriction portion includes an insert located inside the shaft, the insert having a cross-sectional flow area smaller than that of the shaft.
An apparatus according to any one of the preceding claims, wherein the shaft has a cylindrical side wall defining one or more apertures proximate its distal end.
An apparatus according to any one of the preceding claims, wherein the body includes a terminal for mounting the shaft, and the apparatus further includes an adaptor for mounting two or more conduits to the terminal, at least one conduit being an irrigation conduit for delivering irrigation fluid to the terminal, and at least one conduit being a suction conduit for providing a negative pressure at the terminal.
A shaft for a suction and irrigation apparatus, the shaft having
- a distal end for juxtaposition with a body site, and
- a flow restricting portion located proximate its distal end.
