PROBLEM TO BE SOLVED: To provide a system for controlling fluid flow in suction circuit and irrigation circuits during a surgical procedure using selectively moveable valve elements.SOLUTION: The suction circuit comprises: a suction line 52 operatively connected to a surgical instrument 42; a suction exhaust line 54 operatively connected to a waste receptacle 58; a suction vent line 60 connected at a first end to the suction line; and a selectively variable vent valve 62 operatively connected to the suction vent line. The variable vent valve may be selectively moved to vary suction pressure within the suction line. Other fluidics systems are disclosed that include a selectively positionable irrigation valve 64 that may also be incorporated into a fluidics system that includes a variable vent valve.SELECTED DRAWING: Figure 3 【課題】外科手術時において吸引回路および潅注回路中の流体流れを選択的に移動可能な弁要素を用いて制御するシステムを提供する。【解決手段】吸引回路は、外科用器具４２へ動作可能に接続された吸引ライン５２と、排泄物容器５８へ動作可能に接続された吸引排出ライン５４と、吸引ラインにおいて第１の端部へ接続された吸引通気ライン６０と、吸引通気ラインへ動作可能に接続された選択的可変型の通気弁６２とを含む。可変型の通気弁を選択的に移動させることで、吸引ライン内の吸引圧力を変化させ得る。選択的に配置可能な潅注弁６４を含む他の流体工学システムが開示される。潅注弁も、可変型の通気弁を含む流体工学システム内において用いられ得る。【選択図】図３
