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.

Handpiece and blade configurations for ultrasonic surgical instrument

A surgical instrument includes an end effector and a handle assembly. The end effector is configured to operate at a first energy level and at a second energy level. The end effector is further configured to transition between an open position and a closed position. The end effector is configured to grasp tissue in the closed position. The handle assembly includes a body, a trigger, and an activation element. The trigger is configured to pivot in a first direction relative to the body to actuate the end effector from the open position to the closed position. The activation element is configured to activate the end effector at either the first energy level or the second energy level. The trigger is configured to either activate the activation element or determine whether the end effector operates at the first energy level or the second energy level.

Surgical instrument with multi-functioning trigger

An ultrasonic instrument includes a body and a shaft assembly extending distally from the body. The shaft assembly includes an acoustic waveguide. The instrument further includes an end effector including an ultrasonic blade. The ultrasonic blade is in acoustic communication with the acoustic waveguide. The instrument further includes a sensor configured to sense at least one characteristic of the shaft assembly and/or the end effector. The end effector is configured to be activated at varying power levels based on the at least one characteristic sensed by the sensor.

Surgical instrument with variable clamping force

An ultrasonic instrument comprises an ultrasonic transducer, an acoustic waveguide, and an ultrasonic blade. The blade includes a pair of obliquely extending edges. The obliquely extending edges diverge away from the longitudinal axis of the waveguide and away from each other along respective paths extending distally in relation to the waveguide. A distal portion of the blade is wider than a proximal portion of the blade along a plane. The blade further includes a curved distal edge and several laterally presented surfaces. The laterally presented surfaces may provide combinations of concave and convex curvatures. The laterally presented surfaces may be angled and/or curved along one or more orthogonal planes associated with the longitudinal axis of the waveguide.

Ultrasonic surgical blade

A surgical apparatus comprises a body, a user input feature, a shaft assembly, an end effector, and a blade cooling system. The end effector comprises a clamp arm and an ultrasonic blade that may be coupled with an ultrasonic transducer. The clamp arm is configured to pivot toward and away from the ultrasonic blade. The cooling system is operable to deliver liquid coolant to the ultrasonic blade to thereby cool the ultrasonic blade. The user input feature is operable to both actuate the clamp arm and actuate the cooling system.

Features to drive fluid toward an ultrasonic blade of a surgical instrument

An apparatus includes a body assembly, an acoustic waveguide, an ultrasonic blade, a liquid dispensing feature, and a control module. The liquid dispensing feature is positioned distally relative to the body assembly. The liquid dispensing feature is positioned adjacent to the ultrasonic blade. The liquid dispensing feature is configured to deliver a flow of cooling liquid to the ultrasonic blade. The control module is operable to regulate fluid flow through the liquid dispensing feature.

Features and methods to control delivery of cooling fluid to end effector of ultrasonic surgical instrument

An ultrasonic instrument includes a body, an actuation assembly, a shaft assembly, and an end effector. The actuation assembly includes a mode selection member and an activation member. The shaft assembly extends distally from the body. The shaft assembly includes an acoustic waveguide. The end effector includes an ultrasonic blade. The ultrasonic blade is in acoustic communication with the acoustic waveguide. The end effector is configured to be activated in a first activation mode in response to actuation of the activation member when the mode selection member is in a first position. The end effector is configured to be activated in a second activation mode in response to actuation of the activation member when the mode selection member is in a second position.

Surgical instrument with selector

A surgical instrument is disclosed including an end effector, a generator configured to deliver adaptive energy, a mode selector switch having a plurality of surgical modes, a closure switch configured to control the end effector, and a counter configured to count a number of closure switch activations. The surgical instrument is configured to communicate a selected surgical mode of the mode selector switch and the number of closure switch activations from the counter to the generator. The surgical instrument is configured to receive the adaptive energy from the generator based on the selected surgical mode and the number of closure switch activations. The generator is configured to deliver the adaptive energy to the surgical instrument closer to a start of an activation cycle for the selected surgical mode as the number of closure switch activations increases.

Surgical instrument with user adaptable algorithms

An ultrasonic surgical instrument includes a body, a shaft, an ultrasonic transducer, a waveguide, and an end effector coupled to a distal end of the shaft. A rotation knob is rotatably coupled to the body and is configured to rotate the shaft, the waveguide, and the end effector together relative to the body. A torque transfer structure is positioned radially outwardly of and in direct contact with the waveguide at an acoustic node thereof. The torque transfer structure is rotationally fixed relative to the waveguide and is configured to rotationally couple the waveguide with the shaft and the rotation knob. The waveguide includes a first axial constraining feature defining a distally facing surface, and the torque transfer structure includes a second axial constraining feature defining a proximally facing surface configured to abut the distally facing surface to constrain the waveguide axially relative to the torque transfer structure and the body.

Acoustic drivetrain with external collar at nodal position

Aspects of the present disclosure include various ultrasonic surgical instruments. At least one disclosed surgical instrument includes a waveguide including a blade and a transducer base plate. The transducer base plate may be coupled to the waveguide to define a tapered joint at an interface between the waveguide and the transducer base plate. The transducer base plate may include first and second sides defining corresponding first and second flat faces configured to receive first and second piezoelectric elements. The first and second piezoelectric elements are configured to operate in a D31 mode.
