Robotic surgical systems with fluid flow control for irrigation, aspiration, and blowing
First Claim
1. A robotic surgical system, comprising:
- a control console adapted to generate control signals that 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 operable by a user and adapted to respond to the control signals in order to manipulate at least one surgical instrument through a driver element; and
a surgical instrument coupled to the robotic arm, the surgical instrument includinga valve body including a valve opening, the valve opening having an inner cylindrical sidewall, wherein a plurality of openings extend through the inner cylindrical sidewall,a receiving element, the surgical instrument being coupled to the robotic arm in a way that removably couples the receiving element to the driver element,a robotically controlled valve including a shaft coupled to the receiving element and extending into the valve opening, the shaft being rotatable in a fixed axial position about a central axis of the valve opening, wherein the shaft of the robotically controlled valve includes a slanted flow channel extending through the shaft, the flow channel including a first port and a second port that are coupleable to two openings of the plurality of openings, the first port being offset from the second port along a longitudinal axis of the shaft, and wherein the shaft is adapted to rotate, in response to actuation of the receiving element by the driver element in response to the control signals, to couple the two openings to the flow channel and to vary the flow rate of a first fluid through the flow channel in a controlled manner over a range of flow rates between zero and fully open flow, anda hollow tube having a first end coupled to the valve body and a second end with an opening to direct the flow of the first fluid into or out of the surgical site.

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.

14. A robotic surgical system, comprising:
-
a control console operable by a user and adapted to generate control signals associated with a flow of fluid into or out of a surgical site; a robotic arm including a driver element, the robotic arm being coupled to receive the control signals from the control console, the control signals controlling actuation of the driver element; and a surgical instrument removably coupled to the robotic arm, the surgical instrument including; a valve body having a valve opening that includes a cylindrical sidewall, wherein a plurality of openings extend through the cylindrical sidewall; and a first robotically controlled valve, the first robotically controlled valve including a shaft that extends into the valve opening, the shaft being rotatable in a fixed axial position about an axis of the valve opening and being removably coupled to the driver element, the shaft having a slanted flow channel including a first port and a second port that are coupleable to two openings of the plurality of openings, the first port being offset from the second port along a longitudinal axis of the shaft, the flow channel extending through the shaft and turning in response to the actuation of the driver element to provide at least two different fluids into or out of the surgical site, to switch between said two different fluids, and to couple the two openings to the flow channel 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 by rotation of the shaft caused by the driver element in response to the control signals. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22)
