Abstract

A fluid jet cutting system that provides more consistent cutting jet performance is disclosed. The system includes a fluid pump for pressurizing fluid having a fluid inlet and a fluid outlet. The pump delivers pressurized fluid to a delivery tube that is in fluid communication with an end effector. The end effector includes an orifice for delivering pressurized fluid to tissue. The power delivered to the pump is controlled to produce a desired fluid cutting jet.

Claims

1. A fluid jet cutting system controller, comprising:

a fluid pump for pressurizing fluid, including a fluid inlet and a fluid outlet, the pump having a pump motor for driving the pump;

an end effector in fluid communication with the fluid pump and including an orifice for delivering pressurized fluid to tissue; and

a control console electrically connected to the pump motor and adapted to control the pump motor power level.

2. The system of claim 1, wherein the control console includes a processor adapted to receive input from a user and send an output signal to control the pump motor power level.

3. The system of claim 2, wherein the processor can receive a feedback signal from a sensor and can vary the output signal in response to the feedback signal.

4. The system of claim 3, wherein the sensor is positioned to monitor the pump.

5. The system of claim 4, wherein the sensor measures power delivered to the pump.

6. The system of claim 3, wherein the sensor is positioned on the end effector.

7. The system of claim 3, wherein the sensor measures flow rate.

8. The system of claim 3, wherein the sensor measures pressure.

9. The system of claim 1, wherein the pump motor is an electric motor and the control console varies the electrical power delivered to the pump.

10. The system of claim 1, including a delivery tube for receiving pressurized fluid from the pump and delivering the fluid to the end effector.

11. The system of claim 10, wherein the end effector is detachably connected to the delivery tube.

12. The system of claim 10, including multiple end effectors.

13. The system of claim 1, wherein the end effector includes an exit lumen for the removal of cutting fluid.

14. A method of controlling a fluid cutting jet, comprising:

providing a fluid cutting jet system including a fluid pump for pressurizing fluid, the pump having a pump motor for driving the pump, a control console electrically connected to the pump motor and adapted to vary the pump motor power level, and an end effector including a nozzle for delivering pressurized fluid to tissue;

inputting a set point; and

controlling the pump motor power level in response to the set point.

15. The method of claim 14, wherein the set point is representative of fluid jet power

16. The method of claim 14, wherein the control console includes a processor that receives the set point and an output that sets the pump motor power level.

17. The method of claim 14, including the step of providing a feedback signal to the control console from at least one sensor positioned to monitor a system variable of the fluid cutting jet system.

18. The method of claim 17, including the step of varying the pump motor power level in response to the feedback signal.

19. A fluid jet cutting controller system, comprising:

a fluid pump for pressurizing fluid, including a fluid inlet and a fluid outlet, the pump having a pump motor for driving the pump;

a delivery tube for receiving pressurized fluid from the fluid pump and delivering the fluid to an end effector; and

a control console electrically connected to the pump motor and adapted to control the jet power of a fluid cutting fluid by varying pump parameters.

20. The system of claim 19, wherein the control console includes a processor that can receive input from a user and send an output signal to control the pump motor power level.

21. The system of claim 20, wherein the processor can receive a feedback signal from a sensor and can vary the output signal in response to the feedback signal.

22. The system of claim 21, wherein the sensor measures flow rate.

23. The system of claim 21, wherein the sensor measures pressure.

24. The system of claim 21, wherein the sensor measures power delivered to the pump.

25. The system of claim 19, wherein the pump motor is an electric motor and the control console varies the electrical power delivered to the pump.

26. The system of claim 19, including multiple end effectors.
