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 A two position interlocking mechanical switch, coupled to the stem, is extended in the ON valve position and withdrawn in the OFF position.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.

Abstract: The in-line hand operated valve controls the flow of at least one, and preferably both, irrigation fluid and suction respectively to and from a surgical site via a delivery line. In one working embodiment, suction fluid is supplied to the valve via a first source line and suction is supplied to the valve via a second source line. The valve body defines, source ports in fluid communication with the source lines and a delivery port in fluid communication with the delivery line. The valve body includes at least one, and preferably two, collapsible internal fluid carrying channels in fluid communication with the respective source port and the delivery port. Each valve mechanism includes an operator control surface, a stem, and a compressor member acting on and closing and opening the collapsible segment of the fluid carrying channel or body. A biasing element (such as a spring or other resilient body) keeps the valve stem and the compressor element in either an open or a closed state.

Abstract: The present invention provides a device for immobilizing a cannula or sheath which is inserted into a patient's body in a laparoscopic surgical procedure. The device comprises a cannula skirt through which the cannula passes. The skirt contains a leakage cavity therein which is configured to minimize the pull-off forces which would tend to cause a separation of the skirt from the skin to which it is adhered during the surgical procedure. In addition, the leakage cavity provides enhanced flexibility to the cannula skirt so that the cannula can be angled during the procedure without causing excessive stress on the adhesive. A ratchet ring clamp is also provided on the cannula skirt to constrict the cannula skirt and thereby immobilize the cannula after the cannula has been inserted through the skirt.
