ABSTRACT:
A system for controlling the infusion of fluid to an operating field at a selected predetermined pressure, as a counterpart to an instrument for severing material from an object in the field, and for evacuating the severed material from the field in a suspension or emulsion of the infusion fluid. The system includes a feature for preventing a low pressure in the operating field, to thereby prevent a surge of fluid from the field, when the evacuation function is terminated by equalizing the pressure in both the infusion and evacuation lines by supplying both lines with fluid from the same container.
