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 surgical instrument, has an end effector that includes an ultrasonic blade, and a clamp arm that moves relative to the ultrasonic blade from an opened position toward an intermediate position and a closed position. The clamp arm is offset from the ultrasonic blade to define a predetermined gap in the intermediate position between the opened position and the closed position. A clamp arm actuator connects to the clamp arm and moves from an opened configuration to a closed configuration to direct the clamp arm from the opened position toward the intermediate position and the closed position. A spacer connects with the clamp arm to inhibit movement of the clamp arm from the intermediate position toward the closed position for maintaining the predetermined gap between the clamp arm and the ultrasonic blade.

Surgical instrument with selectively actuated gap-setting features for end effector

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 instrument handle

An ultrasonic surgical system is disclosed comprising a surgical instrument and a wrench assembly. The surgical instrument comprises a handle assembly and a body member pivotably coupled to the handle assembly. The handle assembly comprises a first finger grip, an ultrasonic blade, and a waveguide extending proximally from the ultrasonic blade. The body member comprises a second finger grip, a clamp arm movable relative to the ultrasonic blade to capture tissue therebetween, a first body surface defined on a first side of the body member, and a second body surface defined on a second side of the body member. The wrench assembly comprises a wrench and an adapter operably coupled to the wrench. The adapter comprises a first wrench surface configured to engage the first body surface and a second wrench surface configured to engage the second body surface.

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.

Various methods and devices are provided for allowing multiple surgical instruments to be inserted into sealing elements of a single surgical access device. The sealing elements can be movable along predefined pathways within the device to allow surgical instruments inserted through the sealing elements to be moved laterally, rotationally, angularly, and vertically relative to a central longitudinal axis of the device for ease of manipulation within a patient's body while maintaining insufflation.

Surgical access devices and methods providing seal movement in predefined movement regions

A modular energy system that can include a header module removably couplable to one or more energy modules. The one or more energy modules collectively comprise multiple ports to which a surgical instrument is connectable and are each configured to drive a plurality of energy modalities for the surgical instrument. The header module can comprise a display screen configured to display a user interface. The header module is connectable to a footswitch such that the header module can receive a control signal from the footswitch and can send a control signal to the footswitch. The header module can further comprise configured to assign the footswitch to a particular port and, based on user input received via the user interface, reassign the footswitch to another of the ports.

Adaptably connectable and reassignable system accessories for modular energy system

A modular energy system including a header module configured to removably connect to an energy module. The energy module can comprise a port configured to deliver one or more energy modalities to a surgical instrument connected thereto. The header module can comprise a display screen configured to display a user interface. The header module can further include a control circuit configured to detect attachment of energy modules to the modular energy system and control the display of the user interface to display UI portions for each connected module and reconfigure the displayed UI portions to accommodate the new UI portions as additional energy modules are connected to the modular energy system.

Consolidated user interface for modular energy system

Methods and devices for controlling motorized surgical devices are provided. In general, the methods and devices can allow a surgical device to grasp and cut tissue. In some embodiments, the device can include at least one sensor and a motor, and an output of the motor can be configured to be adjusted based at least in part on an output from the at least one sensor. The output of the motor can be configured to provide power for translation of a cutting element along an end effector of the device. Adjusting the motor's output can cause the cutting element to translate through the end effector at different speeds, thereby allowing the cutting element to cut through tissue being grasped by the end effector at different speeds.
