    摘要: An electrically powered surgical instrument includes a surgical end effector having a surgical procedure effecting actuation assembly. A handle is coupled with the end effector. An electric motor is disposed within a shell of the handle and has power terminals and a drive train actuating the assembly when the motor is supplied with power. A break-before-make power supply switch at the handle selectively controls supply of power to the motor. A post-termination braking circuit electrically short-circuits the power terminals when the switch does not supply power to the motor. A method for post-termination braking of an electrical motor utilizes the permanent magnetic field of the motor to counteract an inertia-induced over-stroke characteristic of the motor, drive train, and/or actuation assembly after powered operation by short-circuiting the still-spinning motor to create an electrically generated magnetic field in opposition to the permanent magnetic field upon ceasing supply of power to the motor.

    摘要: An ultrasonic surgical assembly includes an ultrasonic transducer operable to convert a received motional current into a movement of a cutting blade of an ultrasonic waveguide, a measurement circuit connected in a parallel configuration with the ultrasonic transducer, a variable power source operable to supply current through a set of connection points to the parallel configuration and thereby create the motional current in the ultrasonic transducer, and a current controller operable to regulate the motional current by varying an output of the variable power source, thereby maintaining a substantially constant rate of movement of the cutting blade across a variety of cutting loads.

    摘要: A method of maintaining a constant movement of a cutting blade of an ultrasonic waveguide includes providing an ultrasonic transducer operable to convert a received motional current into a movement of a cutting blade of an ultrasonic waveguide, a measurement circuit connected in a parallel configuration with the ultrasonic transducer, and a variable power source operable to supply current through a set of connection points to the parallel configuration and thereby create the motional current in the ultrasonic transducer. Current is supplied through a set of connection points of the parallel configuration with the variable power source to, thereby, create the motional current in the ultrasonic transducer and the motional current is regulated with a current controller by varying an output of the power source, thereby maintaining a substantially constant rate of movement of the cutting blade across a variety of cutting loads.
