摘要： An ultrasonic surgical instrument is disclosed including an end effector and a handle assembly. The end effector includes an ultrasonic blade and a clamp arm movable relative to the ultrasonic blade between an open position and a closed position. The handle assembly includes a handle comprising a pivot pin, a trigger pivotable relative to the handle about the pivot pin, and a yoke operably coupled to the trigger. The yoke is longitudinally movable between a proximal position and a distal position based on pivotable movement of the trigger relative to the handle. The yoke defines an opening. The pivot pin extends into the opening. The opening defines an actuator travel stop configured to contact the pivot pin to prevent overtravel of the trigger.

摘要： Biomarkers are collected and used to determine biological propensities of a patient, to determine the efficacy of medical devices, to select and administer therapeutic agents, to select medical devices, to make adjustments to medical devices, and/or to adjust surgical techniques. An apparatus includes a port to draw a biological fluid (e.g., a mist) from a surgical site. The apparatus includes a sensor having a cantilevered beam. The beam includes substances selected to attract certain biomarkers as the fluid is communicated across the beam. The same apparatus or another apparatus is used to administer a therapeutic agent based at least in part on collected biomarker data. The therapeutic agent delivery apparatus may include a device that is also used to create a wound at a surgical site. For instance, a harmonic surgical instrument may be used to both collect biomarkers and administer a therapeutic agent (e.g., gene therapy using sonoporation).

摘要： An ultrasonic surgical blade includes a body having a proximal end, a distal end, and an outer surface. The distal end is movable relative to a longitudinal axis in accordance with ultrasonic vibrations applied to the proximal end. At least a portion of the outer surface of the body comprises a lubricious coating adhered thereto. The lubricious coating has a coefficient of friction that is less than the coefficient of friction of the outer surface of the body.

摘要： A surgical instrument for use by an operator in a surgical procedure includes an elongate shaft, an end effector extending from the elongate shaft, and a control system. The end effector is articulatable relative to the elongate shaft between a home state position and an articulated position. The control system includes a processor and a memory coupled to the processor to store program instructions. The processor can alert the operator when the end effector reaches the home state position from the articulated position.

摘要： The present disclosure provides a method for controlling a surgical instrument. The method includes connecting a power assembly to a control circuit, wherein the power assembly is configured to provide a source voltage, energizing, by the power assembly, a voltage boost convertor circuit configured to provide a set voltage greater than the source voltage, and energizing, by the voltage boost convertor, one or more voltage convertors configured to provide one or more operating voltages to one or more circuit components.

摘要： Various systems and methods for controlling an ultrasonic surgical instrument according to the location of tissue grasped within an end effector are disclosed. A control circuit can be configured to apply varying power levels, via a generator, to an ultrasonic transducer driving an ultrasonic electromechanical system to oscillate an ultrasonic blade. Further, the control circuit can measure impedances of the ultrasonic transducer corresponding to the varying power levels and determine a location of tissue positioned within the end effector according to a difference between the impedances of the ultrasonic transducer relative to a threshold.

摘要： 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.

摘要： 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, an end effector, and a rotational knob operable to rotate the transmission assembly and the end effector. The body assembly includes a trigger and a casing having a distal aperture configured to receive a portion of the end effector assembly. First and second coupling mechanism portions cooperatively couple the end effector assembly to the body assembly for use. The coupling may mechanically and/or electrically couple the end effector assembly to the body assembly via various coupling mechanisms. For instance, a threaded slip nut may couple to threads within the body assembly. In one configuration, the end effector assembly may have locking tabs that rotate into rotational recesses in the body assembly. The locking tabs may include electrical contacts and/or optically perceivable indicators.

摘要： An electrosurgical instrument is disclosed including a pencil-grip handle, a shaft coupled to the pencil-grip handle, and an end effector coupled to the shaft. The end effector includes a body, a source electrode, and one or more return electrodes. The source electrode and the one or more return electrodes are configured to provide a multi-phase bipolar electrosurgical signal to tissue. The one or more return electrodes each comprise a first return electrode and a second return electrode. The electrosurgical instrument further includes an electrosurgical generator coupled to the end effector. The electrosurgical generator is configured to produce the multi-phase bipolar electrosurgical signal including a first phase, a second phase, and a third phase. The electrosurgical generator is coupled to the source electrode, the first return electrode, and the second return electrode. The first phase, the second phase, and the third phase are combined to generate the multi-phase bipolar electrosurgical signal.
