유체역학 시스템의 다양한 배열이 개시된다. 하나의 배열에서, 흡인을 선택적으로 제어하는 유체역학 시스템을 위한 흡인 회로가 개시된다. 흡인 회로는 수술 장비에 작동적으로 연결되는 흡인 라인, 폐기물 용기에 작동적으로 연결되는 흡인 배출 라인; 제1 단부에서 흡인 라인에 연결되는 흡인 벤트 라인; 및 흡인 벤트 라인에 작동적으로 연결되는 선택적 가변 벤트 밸브를 포함한다. 가변 벤트 밸브는 흡입 라인 내의 흡입 압력을 선택적으로 변화시키도록 움직일 수 있다. 가변 벤트 밸브를 포함 유체역학 시스템에 통합될 수 있는 선택적 위치 가능 관주 밸브를 포함하는 다른 유체역학 시스템이 개시된다. An aspiration circuit for a fluidics system (11) for selectively controlling aspiration, including an aspiration line (52) operatively connected to a surgical instrument; an aspiration pump to create an aspiration flow in the aspiration line; an aspiration exhaust line (54) operatively connected to the aspiration pump on one end and to a waste receptacle (58) on an opposing end; an aspiration vent line (60) connected at a first end to the aspiration line between the aspiration pump and the surgical instrument; and a selectively variable vent valve (62) operatively connected to the aspiration vent line (60), wherein the variable vent valve (62) may be selectively moved to selectively change aspiration pressure within the aspiration line; The aspiration circuit further includes an irrigation line (50) operatively connected to the surgical instrument (42); an irrigation pressure sensor (475) and an actuator, the irrigation pressure sensor being positioned to detect irrigation pressure in the irrigation line and the actuator being operatively connected to the vent valve; wherein the irrigation pressure sensor (475) and the actuator are connected to a controller, and wherein the controller (40) is operative to initiate the actuator to move the vent valve in response to pressure detected by the irrigation pressure sensor to vary the aspiration pressure within the aspiration line (52).
