An ultrasonic surgical instrument includes an end effector with an ultrasonic blade, an acoustic waveguide, an ultrasonic transducer assembly, and a carrier. At least a proximal portion of the acoustic waveguide extends along a longitudinal axis. The ultrasonic transducer assembly is operatively coupled with the acoustic waveguide. The carrier is configured to translate the end effector. The carrier includes a carriage and a translation driver. The carriage movably supports the ultrasonic transducer assembly along the longitudinal axis. The translation driver is configured to translate the carriage and the ultrasonic transducer assembly along the longitudinal axis so that the ultrasonic transducer assembly moves from a proximal position along the longitudinal axis to a distal position along the longitudinal axis for inserting the ultrasonic blade into a patient.

A robotic manipulator includes an arm including at least one joint driven by a transmission comprising an output, an isolation mechanism coupled to the output of the transmission, and a force/torque sensor coupled to the isolation mechanism. The force/torque sensor includes a body, which includes a stationary part and a movable part coupled to and being movable relative to the stationary part. The force/torque sensor also includes one or more sensing elements configured to sense forces and torques applied to the movable part. The isolation mechanism is configured to deform in response to forces induced by the transmission to mechanically isolate the force/torque sensor from forces induced by the transmission.

A telesurgical system may comprise a teleoperated manipulator and a control system to execute instructions to perform operations. The operations may comprise determining a remaining usable life value of a surgical instrument. The surgical instrument may comprise a distal end component and an actuation component coupled to move the distal end component when driven by the teleoperated manipulator. The operations may also comprise monitoring an amount of use of the actuation component during a use of the surgical instrument. Monitoring the amount of use of the actuation component comprises determining the amount of use of the actuation component based on a force or torque on the actuation component. The operations may also comprise updating the remaining usable life value to an updated usable life value of the surgical instrument based at least on the amount of use of the actuation component during the use of the surgical instrument.

A method of verifying torque measurements of a reaction torque transducer of an instrument drive unit includes a controller receiving a verification signal, generating an acceptable range of torques, receiving a torque signal, comparing the torque signal to the acceptable range of torques, and stopping a motor if the torque applied by the motor is outside of the acceptable range of torques. The verification signal is indicative of the current drawn by the motor and the torque signal is indicative of torque applied by the motor.

Techniques for controlling an end effector include a first engagement member coupled to a first actuator, a second engagement member coupled to a second actuator; and a control unit. The control unit is configured to engage the first engagement member with a third engagement member of an instrument, where movement of the third engagement member causes a movement of a degree of freedom (DOF) of an end effector in a first direction; engage the second engagement member with a fourth engagement member of the instrument, where movement of the fourth engagement member causes a movement of the DOF in a second direction opposite the first direction; actuate the DOF in the first direction to a first detectable position; actuate the DOF in the second direction to a second detectable position; and actuate the DOF to a third position between the first and second detectable positions.

A system and method for a system and method for providing an electronic signature as a method and apparatus for sizing bone for press fit arthroplasty. Electrical signatures of driving motive systems used in bone preparation for the press fit arthroplasty, such as driving motors of reamers and broaches, provide a metric for proper sizing.

Techniques are described for testing whether an end effector, or component thereof, is correctly or incorrectly installed to a manipulation system. In an example, a manipulation system can include a manipulator arm configured to receive an end effector having a first moveable jaw, a transducer configured to provide first effort information of the end effector as the end effector moves, and a processor configured to provide a command signal to effect a first test move of the first moveable jaw, and to provide an installation status of the of the end effector using the first effort information of the first test move.

Controls systems and methods are provided for controlling a surgical clip applier for applying surgical clips to a vessel, duct, shunt, etc., during a surgical procedure are provided. In an exemplary embodiment, a control system is provided for controlling at least one motor coupled to a drive system on a surgical clip applier device for driving one or more drive assemblies and thereby actuating one or more actuation assemblies. The control system can be configured to communicate with the drive system of the clip applier tool and to control and modify movement of one or more drive assemblies and actuation assemblies based on certain feedback.
