Abstract
The in-line hand operated valve controls the flow of at least the irrigation fluid or suction to a surgical site. First and second sources provide fluid and suction to the valve. Valve body source ports communicate with the source lines and a delivery port communicates with a delivery line. The valve includes collapsible internal fluid carrying channels linking these ports. Each valve mechanism includes an operator control surface, a stem, and a compressor member acting on and closing and opening the collapsible channels. A biasing element keeps the stem and compressor either open or closed. A two position interlocking mechanical switch, coupled to the stem, is extended in the ON valve position and withdrawn in the OFF position. The method of providing a valve control utilizes these shape and click open and click close systems.
