A method for determining motional branch current in an ultrasonic transducer of an ultrasonic surgical device over multiple frequencies of a transducer drive signal. The method may comprise, at each of a plurality of frequencies of the transducer drive signal, oversampling a current and voltage of the transducer drive signal, receiving, by a processor, the current and voltage samples, and determining, by the processor, the motional branch current based on the current and voltage samples, a static capacitance of the ultrasonic transducer and the frequency of the transducer drive signal.

Surgical generator for ultrasonic and electrosurgical devices

A generator comprising an interface and a control circuit is disclosed. The interface is to electrically couple to an ultrasonic surgical instrument comprising a switch. The switch is configurable between a first switch state and a second switch state. The control circuit is to provide a continuous drive signal to the ultrasonic surgical instrument based on the switch being in the first switch state. The control circuit is to provide a pulsed drive signal to the ultrasonic surgical instrument based on the switch being in the second switch state.

Generator for use with an ultrasonic surgical instrument

Surgical instruments and/or fastener apparatuses comprising an end effector with a pair of jaws pivoted at a proximal end thereof and movable between an open and closed position. At least one of the jaws may comprise a channel for receiving a cartridge containing a plurality of surgical fasteners. Also, an electrically powered actuator may be for deploying the surgical fasteners and may comprise a power source and a motor. An activation mechanism may be attached to the handle to move the pair of jaws from the open to the closed position and to activate the actuator. A lockout mechanism may be configured to permit current to flow from the power source to the motor when the pair of jaws is in the closed position and to prevent current from flowing to the power source to the motor when the pair of jaws is in the open position.

Surgical systems comprising a control circuit including a timer

A surgical instrument is disclosed. The surgical instrument includes a control unit and a staple cartridge including a transponder. The control unit is configured to transmit a first wireless signal to the transponder and to receive a second wireless signal from the transponder to determine one of a first electronic state and a second electronic state of the transponder based on the second wireless signal.

Surgical instrument with wireless communication between control unit and sensor transponders

A surgical stapling assembly is disclosed comprising a shaft, an end effector attached to the shaft, an electric motor, a plurality of sensors positioned within the end effector to measure an electrical parameter, and a control circuit. The end effector comprises a first jaw, a second jaw movable relative to the first jaw, and a firing driver to deploy staples and cut tissue. The electric motor is to actuate the firing driver. The control circuit is to actuate the electric motor to deploy staples from a staple cartridge during a firing stroke, monitor the electrical parameter at a first location of the firing stroke, and monitor the electrical parameter at a second location of the firing stroke, wherein the first location and the second location are different.

Surgical cutting and fastening instrument comprising a plurality of sensors to measure an electrical parameter

A surgical instrument for use with a robotic system that has a control unit and a shaft portion that includes an electrically conductive elongated member that is attached to a portion of the robotic system. The elongated member is configured to transmit control motions from the robotic system to an end effector.

Surgical stapling instrument for use with a robotic system

Various embodiments are directed to a method of driving an end effector coupled to an ultrasonic drive system of a surgical instrument. The method comprises generating at least one electrical signal. The at least one electrical signal is monitored against a first set of logic conditions. A first response is triggered when the first set of logic conditions is met. A parameter is determined from the at least one electrical signal.

Devices and techniques for cutting and coagulating tissue

A control circuit is disclosed that comprises a resistor and a switch network. The switch network is configured to transition between a plurality of states corresponding to a plurality of operational modes of a surgical instrument. In a first phase of a control signal, the control circuit is configured to communicate surgical instrument information to a surgical generator. In the second phase of the control signal and when the at least one switch of the switch network is in a first state of the plurality of states, the control circuit is configured to provide an output corresponding to one of the plurality of states. In the second phase of the control signal and when the at least one switch of the switch network is in a second state of the plurality of states, the control circuit is configured to provide a second output.

Surgical system including a control circuit and a passively-powered transponder

A surgical instrument comprising an end effector, a staple firing drive, and a motor control system is disclosed. The end effector includes a replaceable unspent staple cartridge comprising staples. The staple firing drive comprises an electric motor circuit including an electric motor. The staple firing drive further comprises a firing member movable through a firing stroke by the electric motor. The firing member comprises a tissue cutting knife. The staples are deployable from the staple cartridge based on movement of the firing member through the firing stroke. The motor control system comprises a current sensor and a position sensor. The motor control system is configured to change the operation of the electric motor based on an input from the current sensor. The motor control system is configured to change the operation of the electric motor based on an input from the position sensor.

Surgical instrument including a motor control system

A process and system are disclosed for downloading sensor data, stored in a memory device of a surgical cutting and fastening instrument, to an external or remote computer device. The process may involve storing data from one or more sensors of a surgical cutting and fastening instrument in a memory device of a control unit of the surgical cutting and fastening instrument during a surgical procedure involving the surgical cutting and fastening instrument. Next, after the surgical procedure, a data link between the control unit and the remote computer device is established. Then, the sensor data can be downloaded from the control unit to the remote computer device.
