Surgical device using water jet and method for operating said device
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.
1. A method of operating a water jet surgical device comprising:
connecting a surgical instrument to the water jet surgical device;
generating control signals for controlling a fluid feed device such that fluid is fed to the surgical instrument until said instrument is substantially filled as far as an outlet nozzle thereof; and
ending the control signals and generating an operating release signal such that operation of the fluid feed device for use of the water jet surgical device is permitted, wherein said generating step occurs in response to an input signal from an input device and causes the fluid feed device to transport a predetermined amount of fluid.
2. The method of claim 1 , wherein the surgical instrument is filled until a sensor indicates that the surgical instrument is substantially filled.
3. The method of claim 1 , wherein the surgical instrument is filled until a pressure sensor indicates that the surgical instrument is substantially filled.
4. The method of claim 1 , wherein the surgical instrument is filled until a moisture sensor indicates that the surgical instrument is substantially filled.
5. The method of claim 1 , wherein upon activation of the surgical device, said method further comprises determining a quantity of fluid delivered from the surgical instrument.
6. The method of claim 5 , further comprising displaying the quantity of fluid delivered from the surgical instrument on a display device.
7. The method of claim 5 , further comprising recording the quantity of fluid delivered from the surgical instrument in a recording device.
8. A method of operating a water jet surgical device comprising:
connecting a surgical instrument to the water jet surgical device;
generating control signals for controlling a fluid feed device such that fluid is fed to the surgical instrument until said instrument is substantially filled as far as an outlet nozzle thereof;
ending the control signals and generating an operating release such that operation of the fluid feed device for use of the water jet surgical device in an operation is permitted, wherein said generating of the control signals occurs in response to an input signal from an input device and causes the fluid feed device to transport a predetermined amount of fluid; and
determining a quantity of fluid delivered from the surgical instrument during the operation.
