A surgical instrument operable to sever tissue includes a body assembly and a selectively coupleable end effector assembly. The end effector assembly may include a transmission assembly and an end effector. The body assembly includes a trigger and a casing configured to couple with the transmission assembly. An information transmission system transmits instrument information received from a sensor, for example, to a secure server via a secure gateway connected to the instrument. The instrument may be previously tested on a calibration kit to pre-determine and load surgeon-specific settings onto the instrument prior to use.

Surgical instrument usage data management

An apparatus includes a shaft assembly, an ultrasonic blade, and a clamp assembly. The shaft assembly includes an acoustic waveguide operable to transmit ultrasonic vibrations to the blade. The clamp assembly includes a clamp arm pivotable toward and away from the blade about a pivot axis, to clamp tissue between the clamp arm and the blade. A rotation feature may provide rotation of the blade relative to the clamp arm about the longitudinal axis of the waveguide. Alternatively, the rotation feature may provide rotation of the clamp arm relative to the blade about the longitudinal axis. The rotation feature may be driven based on pivotal positioning of the clamp arm relative to the blade about the pivot axis. The rotation feature may selectively lock and unlock the angular position of either the blade or the clamp arm about the longitudinal axis at any of a number of predetermined angular positions.

Rotation features for ultrasonic surgical instrument

An apparatus comprises a body assembly, a shaft, an acoustic waveguide, an articulation section, an end effector, an articulation drive assembly, and a locking feature. The shaft extends distally from the body assembly. The waveguide comprises a flexible portion. The articulation drive assembly is operable to drive articulation of the articulation section to thereby deflect the end effector from the longitudinal axis of the shaft. The articulation drive assembly comprises an actuator. The actuator is movable relative to the body assembly to drive articulation of the articulation section. The locking feature is in communication with the actuator. The locking feature is movable between an unlocked state and a locked state. The locking feature is configured to permit movement of the actuator relative to the body assembly in the unlocked state. The locking feature is configured to prevent movement of the actuator relative to the body assembly in the locked state.

Ultrasonic surgical instrument with articulation joint having plurality of locking positions

An apparatus includes a body, a shaft assembly, an end effector, and an articulation section. The articulation section is longitudinally interposed between a distal end of the shaft assembly and a proximal end of the end effector. The articulation section is configured to flex to thereby provide deflection of the end effector away from the longitudinal axis of the shaft assembly. The articulation section includes a first frame member, a second frame member, and a sleeve. The proximal end of the second frame member is proximal to the proximal end of the first frame member. The sleeve is disposed about the first and second frame members.

Articulation section for shaft assembly of surgical instrument

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.

Ultrasonic device for cutting and coagulating

An apparatus comprises a body assembly, a shaft, an acoustic waveguide, an articulation section, an end effector, and an articulation drive assembly. The shaft extends distally from the body assembly and defines a longitudinal axis. The acoustic waveguide comprises a flexible portion. The articulation section is coupled with the shaft. A portion of the articulation section encompasses the flexible portion of the waveguide. The articulation section comprises a plurality of body portions aligned along the longitudinal axis and a flexible locking member. The flexible locking member is operable to secure the body portions in relation to each other and in relation to the shaft. The end effector comprises an ultrasonic blade in acoustic communication with the waveguide. The articulation drive assembly is operable to drive articulation of the articulation section to thereby deflect the end effector from the longitudinal axis.

Method of operating an articulating ultrasonic surgical instrument

A surgical instrument includes a shaft assembly, an ultrasonic blade, and a cleaning device. The shaft assembly includes a first tube and an acoustic waveguide. The first tube has a first inner diameter and a distal end. The waveguide has a first outer diameter. The waveguide extends within the first tube. The first outer diameter of the acoustic waveguide and the first inner diameter of the first tube together define a gap. The ultrasonic blade extends distally from the distal end of the first tube. The acoustic waveguide is configured to communicate ultrasonic energy to the ultrasonic blade. The cleaning device is configured to actuate within the gap to thereby clean at least a portion of the shaft assembly and/or at least a portion of the ultrasonic blade.

Ultrasonic surgical instrument with blade cleaning feature

An ultrasonic forceps comprises a housing, an acoustic assembly, and a tine. The housing joins the acoustic assembly and the tine to the forceps and permits the tine to pivot relative to the acoustic assembly. The acoustic assembly comprises a transducer, a waveguide, and ultrasonic blade, and a waveguide sheath. The transducer is configured to generate ultrasonic vibrations directing the ultrasonic vibrations to the waveguide. The waveguide communicates the ultrasonic vibrations distally to the ultrasonic blade. The ultrasonic blade is configured to vibrate in response to the ultrasonic vibrations generated by the transducer. When the tine is pivoted relative to the transducer, the tine is configured to move toward the ultrasonic blade. Tissue may be grasped between the tine and the ultrasonic blade. The tissue may be denatured when the ultrasonic vibrations generated by the transducer vibrate the ultrasonic blade, thus resulting in the tissue being cut and/or sealed.

Ultrasonic forceps

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.
