Abstract

A water jet instrument may be used for manually performing surgery. The water jet instrument may be manually controlled or controlled by a system with a robotic control. The water jet apparatus defines a jet cutting area that is based at least in part on a flow rate meter and a feedback loop.

Claims

1. A medical method comprising:

providing a water jet system, wherein the water jet system comprises a water jet fluid flush tube and an aspiration tube, wherein the water jet fluid flush tube and the aspiration tube are adjacently disposed relative to one another;

endoscopically inserting the water jet system into a patient;

applying fluid from the water jet flush tube to create a cutting jet area to break apart tissue; and

using the adjacently aspiration tube to remove the broken apart tissue via aspiration.

2. The medical method of claim 1, wherein during aspiration, a distal tip of the aspiration tube is not aligned with a distal tip of the water jet fluid tube.

3. The medical method of claim 1, further comprising attaching the water jet system to an arm.

4. The medical method of claim 3, wherein the arm is a robotic arm.

5. The medical method of claim 4, wherein the robotic arm is coupled to the water jet system via an instrument drive mechanism.

6. The medical method of claim 1, wherein the cutting jet area is controlled at least in part on a flow rate meter.

7. The medical method of claim 6, wherein the flow rate meter utilizes a feedback loop to a pump, wherein the feedback loop is controlled by a central processing unit.

8. The medical method of claim 1, wherein the water jet system is manually controlled.

9. The medical method of claim 1, wherein the fluid comprises a saline solution.

10. The medical method of claim 1, wherein the water jet system comprises a central processing unit for controlling the aspiration tube.

11. The medical method of claim 1, further comprising moderating a flow of the fluid from the water jet flush tube based on a measured aspiration flow of the aspiration tube.

12. The medical method of claim 11, wherein moderating the flow is based on a throttle valve or pump control.

13. A medical method comprising:

providing a water jet system, wherein the water jet system comprises a water jet fluid flush tube and an aspiration tube, wherein the water jet fluid flush tube and the aspiration tube are adjacently disposed relative to one another;

endoscopically inserting the water jet system into a patient;

utilizing ultrasound to localize the water jet system within the patient;

applying fluid from the water jet flush tube to create a cutting jet area to break apart tissue;

using the adjacently aspiration tube to remove the broken apart tissue via aspiration.

14. The medical method of claim 13, further comprising attaching the water jet system to an arm.

15. The medical method of claim 14, wherein the arm is a robotic arm.

16. The medical method of claim 15, wherein the robotic arm is coupled to the water jet system via an instrument drive mechanism.

17. The medical method of claim 13, wherein the cutting jet area is controlled at least in part on a flow rate meter.

18. The medical method of claim 17, wherein the flow rate meter utilizes a feedback loop to a pump, wherein the feedback loop is controlled by a central processing unit.

19. The medical method of claim 13, further comprising moderating a flow of the fluid from the water jet flush tube based on a measured aspiration flow of the aspiration tube.

20. The medical method of claim 19, wherein moderating the flow is based on a throttle valve or pump control.
