Abstract

For water-jet surgery pump devices are known by means of which a sterile fluid is transported through a reservoir to the surgical instrument by means of piston pumps or similar volumetrically transporting pumps. In accordance with the present invention it is proposed either to construct drive means for the pumps in such a way that their suction cycle is shorter than the output cycle, or to provide a pump with at least three pump chambers and to construct the drive means in such a way that the suction and output cycles of the pump chambers overlap one another.
