Tri-tubular suction irrigation device

A suction-irrigation device comprising:

• (a) a disposable multi-tubular cassette having a single output and a plurality of input channels in interior fluid communication with said output all of said channels lying essentially in a first plane;
• (b) an elongated housing having a principal elongated central axis and being formed in a plurality of parts, at least two of said parts having interior surfaces, one of said interior surfaces being adapted for receiving, engaging and holding said cassette;
• and
• (c) a plurality of trumpet valve controllers generally disposed along said central axis, said trumpet valve controllers severally engaging different ones of said input channels normally to squeeze said channels and prevent fluid flow therethrough, and when individually operated, to selectively reduce said squeeze on said channels and selectively control fluid flow therethrough, said trumpet valves each including an exterior end connected with a camming pin and an inclined plane normally engaging said camming pin, whereby, when said piston is depressed, said camming pin is correspondingly moved along said inclined plane thereby correspondingly moving said camming pin in a direction transverse to the longitudinal axis of said piston.

A suction-irrigation device comprising:

• (a) a tri-tubular member having a single output and a plurality of elongated input channels in interior fluid communication with said output, all of said channels lying essentially in a first plane and, over a major portion of their
• (b) an elongated housing having a principal elongated central axis and being formed in a plurality of parts, at least two of said parts having interior surfaces, one of said interior surfaces being adapted for engaging said multi-tubular member and a second of said two of said parts being formed integrally with said multi-tubular member;
• and
• (c) a plurality of trumpet valve controllers generally disposed along said central axis, said trumpet valve controllers severally engaging different ones of said input channels normally to squeeze said channels and prevent fluid flow therethrough, and when individually operated, to selectively reduce said squeeze on said channels and selectively control fluid flow therethrough.
