A medical suction and irrigation apparatus includes a suction/irrigation tip removably connected to a conventional suction/irrigation handpiece. Suction is provided through a suction tube which has a bypass conduit in the tip. The bypass conduit is directly connectable to a suction source so that aspirated debris passes through the tip to the suction source. The suction tube thus prevents aspirated debris from entering the conventional suction tube in the handpiece and contaminating the handpiece. The suction tube is also designed to have a maximum size to prevent the tip from clogging. The tip also has an irrigation tube for directing irrigation liquid to the irrigation site, and a connector which connects the irrigation tube to the handpiece so that the handpiece pumps fluid through the tip in a conventional manner. A flexible splash shield, slidably mounted to the irrigation tube, confines irrigation fluid to the local site.

A medical irrigation pump and pump system utilize a permanent non-sterile drive motor capable of operating disposable sterile single use pump units each of which is specifically designed for a particular medical procedure. The pump units have housing which are adapted to be interchangeable within the permanent controller system. Only the sterilized and disposable pump units come into contact with the fluid pathway during pumping. A pattern of bumps on each pump unit is unique for the medical procedure for which the pump unit was designed. The pattern of bumps engages switches on the controller, enabling the controller to identify what type of pump unit has been installed. After automatically identifying the type of pump unit and the intended medical procedure, the controller automatically selects a default motor speed that will provide an appropriate fluid pressure for that particular procedure. Buttons on a control panel also enable the user to manually adjust the pressure delivered by the pump. The orientation of the pump unit during the loading procedure allows easy purging of all air from the pump unit before the pump is started.
