  • Patent number: 10993717
    Abstract: A surgical stapling system is disclosed comprising an end effector configurable in an open configuration and a clamped configuration. The end effector comprises a firing member that moves toward an ending position in response to a firing motion. A sensor is configured to produce a signal corresponding to the configuration of the end effector. A rotatable drive screw is drivable by an electric motor and is threadably engaged with the firing member such that rotary motion is converted to the firing motion. A control system is configured to evaluate the signal produced by the sensor and allows the electric motor to provide the firing motion to the firing member if the end effector is in the clamped configuration. The control system does not allow the electric motor to provide the firing motion to the firing member if the end effector is in the open configuration.

  • Patent number: 10952727
    Abstract: A surgical stapling instrument comprising a handle, an elongate shaft, an end effector, a motor couplable with a supply of current, a firing member operably responsive to the motor, a current sensor, and a control circuit is disclosed. The firing member is movable from a proximal position to a distal position during a firing stroke. The control circuit comprises a processor and a memory configured to store instructions which, when executed from the memory cause the processor to activate the motor in response to an actuation input, receive an input from the current sensor regarding the current draw of the motor, deactivate the motor when the current draw of the motor exceeds a threshold current when the firing member is within a threshold distance relative to the proximal position, and retract the firing member to the proximal position.

  • Patent number: 10945729
    Abstract: A robotic surgical system comprising a surgical robot, a surgical instrument, a motor, and a current sensor is disclosed. The surgical instrument comprises an end effector, a firing assembly, and a lockout mechanism. The firing assembly comprises a firing member movable from an unfired position to a fired position during a firing stroke and a sled movable from a proximal position to a distal position. The lockout mechanism is configured to prevent the firing stroke when the sled is not in the proximal position. The motor is operably coupled with the firing member and couplable with a supply of current. When the current through the motor exceeds a threshold value the firing member is prevented from completing the firing stroke. The threshold value corresponds to the current through the motor when the lockout mechanism is activated. The motor is de-energized when the current through the motor exceeds the threshold value.

  • Publication number: 20200338370
    Abstract: In one general aspect, various embodiments are directed to a surgical instrument that can supply mechanical energy and electrical energy to an end effector of the surgical instrument. The surgical instrument may be operated in a first operating mode in which a transducer of the surgical instrument produces mechanical energy, or vibrations, that are transmitted to the end effector and a second operating mode in which electrical energy, or current, can flow through the end effector to perform electrosurgery. In another general aspect, the surgical instrument may comprise a clamp, or jaw, which can be moved into a closed position to hold tissue against a waveguide, or blade, of the end effector. In the second operating mode of the surgical instrument, current can flow from a power source, through the waveguide, and return to the power source through a path comprising the jaw.
