Abstract

In one embodiment of the invention, a robotic surgical system is provided including a master control console and a surgical manipulator. The master control console generates control signals to cause one or more fluids to flow into or out of a surgical site. The surgical manipulator is coupled to the console to receive the control signals and includes at least one robotic arm and a surgical instrument coupled thereto. The surgical manipulator controls the surgical instrument in response to the control signals to control the flow of the one or more fluids into or out of the surgical site. The surgical instrument has a first robotically controlled valve that is responsive to the surgical manipulator and a hollow tube having a first end coupled to the first robotically controlled valve with an opening at a second end to direct the flow of one or more fluids.

Claims

1-26. -26. (canceled)

27. A robotic surgical system, comprising:

a control console adapted to generate control signals that provide a user with an ability to vary a flow rate of fluid into or out of a surgical site over a range of flow rates between zero and fully open flow;

a robotic arm in communication with the control console and adapted to respond to the control signals in order to manipulate at least one surgical instrument; and

a surgical instrument coupled to the robotic arm, the surgical instrument including

a robotically controlled valve coupled to a receiving element and having a plurality of ports, wherein the robotically controlled valve is adapted to vary the flow rate of a first fluid into or out of the surgical site in a controlled manner over a range of flow rates between zero and fully open flow in response to the actuation of the receiving element by the driver element, and

a hollow tube having a first end in communication with one of the plurality of ports of the robotically controlled valve and a second end with an opening to direct the flow of the first fluid into or out of the surgical site.

28. The system of claim 27, wherein said control console provides the user with the ability to vary the flow rate of the first fluid in a controlled manner for both incremental increases and incremental decreases between different non-zero and non-fully open flow rates.

29. The system of claim 27, wherein said control console includes a single input device that provides the user with the ability to control the flow rates of a plurality of fluids into or out of the surgical site in a controlled manner.

30. The system of claim 27, wherein said control console provides the user with the ability to vary the flow rates of both an irrigation fluid and a gas into the surgical site.

31. The system of claim 30, wherein said control console further provides the user with the ability to vary the flow rate for removing the irrigation fluid, the gas, or both the irrigation fluid and the gas from the surgical site.

32. The system of claim 27, wherein said control console is further adapted to provide a user with the ability to switch between controlling different fluids at the surgical site.

33. The system of claim 27, wherein said control console includes a handle having one or more grip components, said handle being adapted to provide the user with the ability to vary the flow rate of the fluid over a range of flow rates between zero and fully open flow.

34. The system of claim 33, wherein said handle further includes one or more buttons that activate irrigation, aspiration, blowing, or any combination thereof.

35. The system of claim 27, wherein said control console includes a speech recognition device that is adapted to provide the user with the ability to vary the flow rate of the fluid over a range of flow rates between zero and fully open flow.

36. The system of claim 27, wherein said control console includes one or more foot pedals that are adapted to provide the user with the ability to vary the flow rate of the fluid over a range of flow rates between zero and fully open flow.

37. The system of claim 36, wherein said one or more foot pedals fully control the irrigation and suction of fluids into and out of the surgical site.

38. The system of claim 36, wherein a first foot pedal of said one or more foot pedals is further adapted to control one or more other surgical functions in addition to being adapted to vary the flow rate of the fluid.

39. The system of claim 27, wherein said robotically controlled valve is a trumpet valve or a pinch valve.

40. A robotic surgical system, comprising:

a control console adapted to generate control signals associated with the flow of fluid into or out of a surgical site, wherein the control console provides a user with an ability to control both the switching between two or more different fluids and to vary the flow rate of at least one of said two or more different fluids into or out of a surgical site over a range of flow rates between zero and fully open flow; and

at least one robotic arm adapted to manipulate at least one surgical instrument coupled thereto in response to the control signals, wherein the at least one surgical instrument includes a first robotically controlled valve having a plurality of ports, the first robotically controlled valve being adapted to provide at least two different fluids into or out of the surgical site, to switch between said two different fluids, and to vary the flow rate of at least one of said fluids in a controlled manner over a range of flow rates between zero and fully open flow.

41. The robotic surgical system of claim 40, wherein said control console provides the user with the ability to vary the flow rates of each of said two different fluids in a controlled manner for both incremental increases and incremental decreases between different non-zero and non-fully open flow rates.

42. The robotic surgical system of claim 40, wherein said control console includes one or more foot pedals and is arranged such that said one or more foot pedals provide the user with the ability to vary the flow rate of the fluid over a range of flow rates between zero and fully open flow.

43. The robotic surgical system of claim 42, wherein said control console is arranged such that one or more foot pedals fully control the irrigation and suction of two different fluids into and out of the surgical site.

44. The robotic surgical system of claim 42, wherein said control console is arranged such that a first foot pedal of said one or more foot pedals provides the user with the ability to control one or more other surgical functions in addition to providing the user with the ability to vary a fluid flow rate.

45. The robotic surgical system of claim 42, wherein said control console is arranged such that a first foot pedal of said one or more foot pedals provides the user with the ability to switch from suction control to blow control in order to blow a pressurized gas over the surgical site.

46. The robotic surgical system of claim 42, wherein said control console is arranged such that a first foot pedal provides the user with the ability to control suction to the surgical site and a second foot pedal provides the user with the ability to control irrigation into the surgical site.

47. The robotic surgical system of claim 40, wherein the at least one surgical instrument further includes:

a first manually operated valve arranged in parallel with the first robotically controlled valve, the first manually operated valve also having a plurality of ports and being adapted to vary the flow rate of at least one of said fluids in a controlled manner over a range of flow rates between zero and fully open flow.
