| Zusammenfassung: | Pump devices are known in water-jet surgery, that are used to transport a sterile fluid through a reservoir to the surgical instrument by means of piston pumps or other such volumetric pumps. According to the invention, either drive devices for the pumps are embodied in such a way that the suction cycle thereof is shorter than the output cycle, or a pump comprises at least three pump chambers and the drive devices are embodied in such a way that the suction and output cycles of the pump chambers overlap each other. |
