Claim Text:
1. An irrigation and suction system, in particular for laparoscopic surgery, comprising: an active control apparatus, provided with a reusable motor attached to and operating a disposable pump, and a disposable handpiece provided with two valves capable to be connected respectively to an output duct from the pump and to a suction line, the two valves being operatable for making respectively the pump and the suction line communicate with a single output nozzle of the handpiece, the nozzle being capable to support a probe, the active control apparatus comprising controlling electronics means for driving the motor, wherein the irrigation and suction system comprises interface means connected to said controlling electronics means capable to select an operation mode of the motor between a continuous mode, wherein the pump delivers a fluid in a continuous and uniform way, and a pulse mode, wherein the pump flow rate switches between a minimum flow rate and a maximum flow rate with a switching period, the interface means comprising a keypad with keys suitable to allow to select the operation mode of the motor, wherein the interface means also comprises a graphic display suitable to visualize an operation state of the irrigation and suction system and a man-machine interface electronic module to which said keys and said graphic display are connected, and the interface means are housed on a handpiece, and wherein the handpiece has an ergonomic banana shape with a first elongated arcuate surface extending from the two valves to the output nozzle on a proximal face of the handpiece, a second elongated arcuate surface spaced from the first elongated arcuate surface and extending from the two valves towards the output nozzle, a third elongated arcuate surface extending from the output nozzle towards the second elongated arcuate surface, a pair of buttons which are contiguous with each other and are both disposed adjacent to each other on a distal face of the handpiece between the second and the third elongated arcuate surfaces, wherein the pair of buttons controls the operation of the two valves, whereby when the pair of buttons is pressed the two valves may communicate with the output nozzle.
