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.
