An improved fluid supply and suction apparatus and method for supplying and suctioning fluid through a cannula into and through the body of the fluid supply and suction apparatus is shown. The fluid supply and suction apparatus, which is intended for use in a surgical enviornment, preferably comprises a body having a plurality of ports in fluid communication with a tool insertion thru-hole. The tool insertion thru-hole provides a substantially unobstructed portal from one end of the apparatus body to the other end of the apparatus body. In a more preferred embodiment, the plurality of ports are open to one end of the apparatus body only and they comprise at least a fluid supply port, a fluid suction port, and a regulated port having a suction regular to selectively control the amount of suction through the regulated port. Valves are preferably provided to control flow to and from the ports into and out of the tool insertion thru-hole. In normal operation, fluid supply and suction tubes are connected to each port providing either fluid supply or suction as appropriate. At one end of the apparatus body, a cannula is attached which transports fluid to the surgical site or transports fluid being suctioned from the surgical site. The subject apparatus can be used with fluids comprising gases, liquids or liquids which contained entrained solid matter or mixtures thereof.
