A fluid passageway is defined through the conduit and base portion, an ultrasonic transducer including a plurality of piezoelectric elements and a plurality of electrodes are arranged in a stack configuration, where an electrode is located between each pair of piezoelectric elements. A first borehole is defined through the ultrasonic transducer and an end mass having a second borehole defined therethrough. A surface of the end mass is positioned adjacent a first end of the ultrasonic transducer, the end mass is configured to engage with the housing, and the conduit section of the housing is configured to pass through the second borehole of the end mass. The end mass is configured to compress the ultrasonic transducer against a surface of the housing when the end mass is engaged with the housing.

Ultrasonic surgical instrument with piezoelectric central lumen transducer

An ultrasonic instrument includes a housing, an ultrasonic transducer support by the housing, and an integrated usage indicator. The housing is configured to removably connect to a shaft assembly. The ultrasonic transducer is configured to be acoustically connected to a waveguide and operated a predetermined number of use cycles. The integrated usage indicator is operatively connected to the housing and includes a used state indicator. The used state indicator is configured to indicate to a clinician in a used state when the ultrasonic transducer has been operated at least the predetermined number of use cycles for limiting usage of the ultrasonic transducer to the predetermined number of use cycles.

Surgical instrument use indicator

An apparatus includes a body, a shaft assembly, and an end effector. The end effector includes an ultrasonic blade and a clamp arm assembly. The ultrasonic blade is in acoustic communication with an acoustic waveguide of the shaft assembly. The clamp arm assembly is pivotable toward and away from the ultrasonic blade. The clamp arm assembly includes a first electrode and a second electrode. The first and second electrodes are operable to cooperate to apply bipolar RF energy to tissue.

End effector for instrument with ultrasonic blade and bipolar clamp arm

An ultrasonic surgical system is disclosed including an end effector, an elongate shaft, an articulation joint, and an articulation system. The end effector is rotatable relative to the elongate shaft about the articulation joint. The articulation system includes a distal plate, a first cable, a second cable, and a gear. The distal plate is configured to articulate toward a first side of the gear based on the gear rotating in a first direction and articulate toward a second side of the gear based on the gear rotating in a second direction. The end effector is configured to articulate in a first articulation direction about the articulation joint based on the distal plate articulating toward the first side of the gear. The end effector is configured to articulate in a second articulation direction about the articulation joint based on the distal plate articulating toward the second side of the gear.

Ultrasonic surgical instruments with control mechanisms

The present disclosure is directed to end effectors. An end effector includes an outer shaft extending along a longitudinal axis and an inner shaft partially located within the outer shaft. The end effector may include an ultrasonic blade. The inner shaft may include biased and unbiased portions. The inner shaft and outer shaft may be translatable relative to one another. At one translatable position, the biased portion of the inner shaft may be located within the outer shaft and the unbiased portion may be substantially straight along the longitudinal axis. At another translatable position, the biased portion of the inner shaft may be located outside of and distally positioned from the outer shaft such that the biased portion of the inner shaft is bent away from the longitudinal axis.

Surgical instruments with articulating shafts

A bone cutting surgical instrument includes features to mitigate heat generation during use. Excessive heat can be detrimental to bone health as well as to the instrument itself. In one example a liquid dispensing feature provides a flow of cooling liquid to an ultrasonic blade via a lumen in a waveguide of the instrument. In another example, the blade has a serrated edge with a plurality of teeth arranged in a pattern to provide dimension and space during cutting actions. In another example, the blade has an oversize distal portion that creates an oversize slot when cutting to avoid excessive contact between the cut bone and proximal portions of the blade. In another example the blade includes an irrigation slot and also a micro slot in a distal end of the blade that connects with the irrigation slot.

Ultrasonic surgical instrument blade with heat reduction feature

A surgical instrument includes a temperature sensor and a control unit that is operable to deactivate an end effector of the surgical instrument. In some versions the temperature sensor detects the temperature of a transducer, while in others the temperature sensor detects the temperature of the end effector. The surgical instrument may also include a trigger and a trigger position sensor. A force sensor or a position sensor may be included to determine the force and/or position of the transmission assembly. The end effector may also include a force sensor or a micro coil. A surgical instrument having a sensor may be included in a surgical system that includes a control unit and a remote controller. In some instances the remote controller may have one or more force-feedback components. In addition, a device interface and a surgeon interface may be included to remotely adjust the settings of the control unit.

Surgical instrument with sensor and powered control

A surgical instrument comprises a body assembly and an end effector. The body assembly includes a control module, an orientation sensor communicatively coupled to the control module, and an energy component. The energy component is operable to activate the end effector at a plurality of energy settings. A storage device is communicatively coupled to the control module and includes a plurality of gesture profiles and corresponding energy settings. The control module is configured to set the energy setting of the energy component to a corresponding energy setting in response to a correlation between the output of the orientation sensor and a gesture profile. In some versions, the control module modifies the energy setting based upon output from a force sensor that measures the force on the end effector. The control module may also decrease the energy setting in response to an anomalous acceleration or deceleration detected by an accelerometer.

Surgical instrument with orientation sensing

An ultrasonic instrument comprises a body, a shaft assembly, an ultrasonic blade, and a pivoting member. The shaft assembly extends distally from the body. The ultrasonic blade is positioned distal to the shaft assembly. The pivoting member is pivotable with respect to the blade from an open position to a closed position to thereby clamp tissue between the pivoting member and the blade. One or both of the shaft assembly or the pivoting member comprise a guide feature. The guide feature is configured to provide lateral alignment of the distal portion of the pivoting member with the blade as the pivoting member is pivoted to the closed position.

Alignment features for ultrasonic surgical instrument

A surgical apparatus comprises an instrument body, an end effector, and a control module. The end effector is in communication with the handle assembly. The end effector is operable for use in a surgical procedure. The control module is in communication with the end effector. The end effector with the control module is able to deliver surgical energy as well as nerve excitation energy to a surgical site. A surgeon may detect stimulation of nervous tissue by visually observing the tissue twitch, and may adjust surgical technique accordingly. A sensor may be used to detect excitation of nervous tissue based on excitation caused by the nerve excitation energy.

Surgical instrument with nerve detection feature

A surgical instrument includes an ultrasonic transducer assembly comprising a coupling portion laterally movable at an ultrasonic frequency. In addition, the surgical instrument includes an ultrasonic transmission waveguide extending from the coupling portion and an ultrasonic treatment element defining a cutting surface, wherein the ultrasonic treatment element extends from the ultrasonic transmission waveguide, and wherein the lateral movement of the coupling portion is in a direction perpendicular to a plane defined by the cutting surface of the ultrasonic treatment element.

Ultrasonic assembly for use with ultrasonic surgical instruments

A surgical instrument includes a body assembly, a waveguide, a transducer, and a coupling assembly. In some versions the coupling assembly translates the transducer to couple the transducer to the waveguide. For instance, a gear having arcuate troughs may engage pins on the transducer and/or waveguide to mate the transducer to waveguide. A pawl may selectively engage and prevent rotation of the gear. Alternatively, lever arms may cam the transducer into the waveguide. The lever arms may selectively couple to a casing to prevent decoupling of the transducer and waveguide. In another configuration, a locking tab can be slid and locked into a slot to couple the transducer and waveguide. Further still, levers with self-locking pins may engage and couple the transducer to the waveguide. In another version, a rotatable body portion may engage a tab on the transducer to rotate and couple the transducer to the waveguide.
