    Abstract: Disclosed is a modular hand-held device for use with a suction irrigation electrosurgical tool having a rear inlet/outlet port provided with an electrically conductive surface. It has a rear handle member, a middle valve member and a front member. An electrical connection device is provided for supplying electrical energy to the electrically conductive surface when the rear inlet/outlet port of the suction irrigation electrosurgical tool is received into an inlet/outlet port of the front member. A first mechanical connector is provided for removably connecting front ports of the handle member respectively to the corresponding rear ports of the middle valve member, and a second mechanical connector is provided for removably connecting an inlet/outlet front port of the middle valve member to an inlet/outlet rear port of the front member. This device can be fully dismantled, thereby making it possible to clean and sterilize all its component for further uses.
