Robotic surgical instruments with a fluid flow control system for irrigation, aspiration, and blowing

A robotic surgical system comprising:

• a master control console remotely located from a patient, the master control console configured to generate one or more control signals to variably control one or more controlled valves;
• and
• a robotic surgical instrument including
• a housing configured to couple to a robotic arm;
• a flow control system mounted in the housing;
• a hollow tube having a first end mounted in the housing, the first end of the hollow tube coupled to the flow control system, and a second end of the hollow tube having one or more openings for placement in a surgical site to allow the flow of fluids there-in and there-out;
• and
• one or more hose fittings each having a first end coupled to the flow control system, the one or more hose fittings having a second end to respectively couple to one or more hoses;
• wherein the flow control system includes
• a coupler having a first port coupled to the first end of the hollow tube, the coupler further having second, third, fourth, and fifth ports, the coupler to couple together the first port with the second, third, fourth, and fifth ports to flow fluids there-between;
• one or more controlled valves to variably control the flow of one or more fluids through the robotic surgical instrument in response to the one or more control signals generated by the master control console, the one or more controlled valves including
• a first controlled valve having a first port to couple to a first hose fitting and a second port coupled to the second port of the coupler, the first controlled valve to variably control the flows of a first fluid through the robotic surgical instrument in response to first control signals;
• and
• a second controlled valve having a first port to couple to a second hose fitting and a second port coupled to the third port of the coupler, the second controlled valve to variably control the flows of a second fluid through the robotic surgical instrument in response to second control signals;
• a first manual valve coupled in parallel with the first controlled valve, the first manual valve having a first port to couple to the first hose fitting and a second port coupled to the fourth port of the coupler, the first manual valve being manually actuated by hand to manually control the flows of the first fluid through the robotic surgical instrument, and
• a second manual valve coupled in parallel with the second controlled valve, the second manual valve having a first port to couple to the second hose fitting and a second port coupled to the fifth port of the coupler, the second manual valve being manually actuated by hand to manually control the flows of the second fluid through the robotic surgical instrument.

A robotic surgical system comprising:

• a master control console remotely located from a patient, the master control console configured to generate one or more control signals to variably control one or more controlled valves;
• and
• a robotic surgical instrument including
• a housing configured to couple to a robotic arm;
• a flow control system mounted in the housing, the flow control system including at least two rotatable controlled valves to variably control the flow of one or more fluids through the robotic surgical instrument,
• wherein the flow control system includes
• a three-dimensional solid valve body having
• a first valve opening to receive a first rotatable controlled valve,
• a second valve opening to receive a second rotatable controlled valve,
• a first hollow passage between a first port of the first valve opening, a first port of the second valve opening and a port coupled to the first end of the hollow tube,
• a second hollow passage between a second port of the first valve opening and a port coupled to a first one of the one or more hose fittings, and
• a third hollow passage between a second port of the second valve opening and a port coupled to a second one of the one or more hose fittings;
• the first rotatable controlled valve coupled into the first valve opening of the three-dimensional solid valve body, the first rotatable controlled valve having a cylindrical shaft with a slanted channel to variably control the flow of fluids between the first port and the second port of the first valve opening;
• and
• the second rotatable controlled valve coupled into the second valve opening of the three-dimensional solid valve body, the second rotatable valve having a cylindrical shaft with a slanted channel to variably control the flow of fluids between the first port and the second port of the second valve opening.
