  • Patent number: 9504485
    Abstract: A water jet surgical device comprises a fluid feed device, which is controllable by control signals from a control device, for delivering a fluid into a connecting line of a surgical instrument with an outlet nozzle. The fluid feed device includes at least one measuring device, which is configured such that following the connection of the surgical instrument to the fluid feed device, the measuring device generates measuring signals to represent a quantity of fluid delivered. The quantity of fluid delivered may be displayed on a display or recorded in a recording unit. This enables improved monitoring of surgical operations.

  • Patent number: 8251679
    Abstract: A medical pump for use in water jet surgery which provides ease of connection between a pump unit and a pump actuating device. The medical pump includes a pump unit and a pump actuating device. The pump unit has at least one piston. The pump actuating device includes a holding device and at least one coupling device, the combination of which is configured to connect the pump unit and pistons to the pump actuating device. The pump actuating device includes a drive device controlled by a control system to actuate the pump unit, to open/close the holding device, and to open/close the at least one coupling device. The pump actuating device includes a detection device in communication with the control system that detects a relative position between the pump unit and the pump actuating device and transmits detection signals to the control system.
