Abstract: Various systems and methods for selectively controlling the activation of an ultrasonic surgical instrument according to the presence of tissue within an end effector are disclosed. A control circuit can be configured to determine whether tissue is present within the end effector and permit activation of the ultrasonic transducer at a power level according to whether tissue is present within the end effector. In some aspects, the control circuit can be configured to automatically activate the ultrasonic transducer in response to tissue being detected within the end effector.

Abstract: An end effector of an electrosurgical device may include a fluid discharge port, a fluid aspiration port, and at least two electrodes, in which the electrodes are disposed on a surface of a body of the end effector. The end effector body may include channels fluidically coupled to the fluid discharge port. The end effector body may also include channels to receive the electrodes. The electrodes may be helically wound about the end effector body. The electrodes may interdigitate. An electrosurgical device may include the end effector which is fluidically, mechanically, and electrically coupled to a handle assembly by a shaft assembly. The shaft assembly may be bendable and assume a bent configuration upon the application of a force orthogonal to a longitudinal axis of the shaft assembly. The shaft assembly may retain the bent configuration until the application of a countering force.

The surgical instrument comprises an end effector comprising a first jaw and a second jaw, a first set of electrodes and a second set of electrodes and a slot defined between the first set of electrodes and the second set of electrodes. A cutting member configured to reciprocate within the slot. A control circuit is configured to receive information about impedance of tissue located between the first jaw and the second jaw of the end effector, provide electrosurgical energy to the first set of electrodes and the second set of electrodes and repeatedly alternate the electrosurgical energy between the first set of electrodes and the second set of electrodes at a predetermined time interval, and advance the cutting member.

Abstract: An apparatus comprises a body, a shaft assembly, an end effector, and a shield member. The shaft assembly extends distally from the body. The end effector is located at a distal end of the shaft assembly. The end effector comprises an ultrasonic blade and a clamp arm. The ultrasonic blade is configured to vibrate at an ultrasonic frequency. The clamp arm is movable toward the ultrasonic blade to compress tissue against the ultrasonic blade. The shield member is selectively movable from a first position to a second position in response to movement of the clamp arm toward the ultrasonic blade. The shield member is configured cover at least a first portion of the ultrasonic blade in the first position. The shield member is configured to uncover the first portion of the ultrasonic blade in the second position.

Abstract: Various embodiments are directed to a method of driving an end effector coupled to an ultrasonic drive system of a surgical instrument. In accordance with the method, a generator is configured to generate at least one time varying electrical signal having a resonant frequency, monitor the resonant frequency of the at least one electrical signal, calculate a frequency slope between frequency data points of the time varying electrical signal, where the frequency slope is the change in resonant frequency over time, compare the frequency slope to a threshold frequency slope, and trigger a first response of the generator when the frequency slope crosses the threshold frequency slope.

Abstract: A surgical apparatus comprises a body, an ultrasonic transducer, a shaft, and an end effector. The ultrasonic transducer is operable to convert electrical power into ultrasonic vibrations. The body comprises a pivotal trigger. The shaft couples the end effector and the body together. The end effector comprises a clamp arm and an ultrasonic blade in acoustic communication with the ultrasonic transducer. The ultrasonic blade is operable to deliver ultrasonic vibrations to tissue. Pivotal movement of the trigger causes movement of the clamp arm. The trigger includes a compliant feature configured to limit the amount of force delivered to tissue by the clamp arm. The flexible feature may comprise a flexible band, living hinge, a series of living hinges, or a flexible tab.
