Abstract: A pinch valve mechanism for use in a suction/irrigator device, wherein the device has a conduit for suction/irrigation. The pinch valve mechanism includes a first end having a first projection, a second end, operatively connected to the first end and a second projection. A spring means operatively connected to the second end, wherein the conduit is disposed between the first end and the second end such that the first projection and second projection are biased to pinch the conduit into a closed position. Compression of the spring means moves the first end away from the second end to move the conduit into an open position.

Abstract: A configurable butt for a cue stick comprising a body comprising an elongate chamber having an internal thread and a movable weight coaxially located within the elongate chamber and having an external thread, the movable weight being threadingly coupled to the internal thread of the elongate chamber. An internal shaft extends through the movable weight is adapted to rotate the movable weight within the internally threaded chamber thereby causing the movable weight to move between respective ends of the elongate chamber by virtue of the threaded coupling for adjusting a centre of gravity of the cue stick. An indicator arrangement is coupled to the internal shaft and adapted to provide an indicate of the location of the movable weight within the elongate chamber.

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.
