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 system configured to control operation of an ultrasonic surgical instrument is disclosed. The system comprises a generator configured to generate a signal, and a computer communicably coupled to the generator. The computer is configured to receive a first set of variables corresponding to a first signal at a first power level of the instrument, evaluate the first set of variables with a model to generate a first output, wherein the first output comprises a value between the first set of variables and a condition set, and wherein the condition set comprises a plurality of conditions that correspond to a plurality of responses, determine the first output meets a first threshold value for a first condition; determine a first response corresponding to the first condition, wherein the first response is a second power level for the instrument, and transmit the second power level to the generator for a second signal.

Switch arrangements for ultrasonic surgical instruments

Ultrasonic surgical instruments including a handle housing, a switch frame, and a switch assembly are disclosed. The switch assembly may include a first switch arrangement movably supported on a distal portion of the handle housing and selectively movable relative to a first switch contact supported by the switch frame. The switch assembly may further include a second switch arrangement including a right switch button movably supported on a right side of the handle housing and selectively movable relative to a right switch contact supported by the switch frame, and a left switch button movably supported on a left side of the handle housing and selectively movable relative to a left switch contact supported by the switch frame. The first and second switch arrangements may be configured to be selectively actuatable by a single hand supporting the handle housing.

Various forms are directed to a method for operating an ultrasonic surgical instrument. The ultrasonic surgical instrument may be activated by generating a drive signal provided to the ultrasonic drive system to drive the end effector. A plurality of input variables may be applied to a multi-variable model to generate a multi-variable model output, where the multi-variable model output corresponds to an effect of the ultrasonic instrument on tissue. The plurality of input variables may comprise at least one variable describing the drive signal and at least one variable describing a property of the ultrasonic surgical instrument. When the multi-variable model output reaches a threshold value, feedback may be generated indicating a corresponding state of at least one of the ultrasonic surgical instrument and tissue acted upon by the ultrasonic surgical instrument.

Techniques for cutting and coagulating tissue for ultrasonic surgical instruments

Switch assemblies for handheld ultrasonic surgical instruments. The switch assemblies may include a first switch arrangement that is operably supported on a forward portion of a handle housing of the surgical instrument and is selectively movable relative to at least one first switch contact. The switch assembles may further include a second switch arrangement that comprises at least one of a right switch button that is movably supported on a right side of the handle housing relative to at least one right contact and a left switch button that is movably supported on a left side of the handle housing that is selectively movable relative to at least one left contact.

A connector module for an ultrasonic surgical instrument includes a housing having a spindle and a coupling rotatably mounted on the spindle. A first conductor is mechanically coupled to the housing. A first link is rotatable relative to the first conductor between a first position and a second position and includes a first contact positioned to electrically contact the first conductor and a second contact electrically coupled to the first contact and positioned to electrically contact an ultrasonic hand piece.
