Patent ID: 8002732

Claim:
A medical device, comprising: a housing having a proximal end and a distal end; an attachment structure located at the distal end of the housing and which is configured for coupling to a medical instrument; at least one of a suction port or an irrigation port located at the proximal end of the housing and which is configured for connection to a source of suction or irrigation, respectively; a conduit providing a fluid flow path from the at least one port at the proximal end of the housing to a distal port leading to the medical instrument at the distal end of the housing; a valve housing chamber comprising a ramp that extends along an external surface of the valve housing chamber; and at least one valve configured to move within the fluid flow path to selectively actuate suction or irrigation, wherein the at least one valve is configured to rotate along a path defined by the ramp of the valve housing chamber to permit a first level of suction or irrigation and is configured to axially displace along a longitudinal axis of the valve housing chamber in a non-rotating manner to permit a second, higher level of suction or irrigation.
