An apparatus comprises an electrically power surgical instrument having a handle assembly. The apparatus also comprises a communication device positioned within the handle assembly. The communication device is operable to communicate with at least a portion of the electrically powered surgical instrument. The apparatus further comprises an external device in wireless communication with the communication device. The external device is operable to receive information from the communication device and the external device is operable to provide an output viewable to the user.

Various aspects of a generator, ultrasonic device, and method for estimating and controlling a state of an end effector of an ultrasonic device are disclosed. The ultrasonic device includes an electromechanical ultrasonic system defined by a predetermined resonant frequency, including an ultrasonic transducer coupled to an ultrasonic blade. A control circuit measures a complex impedance of an ultrasonic transducer, wherein the complex impedance as defined as

[00001]$Z_g\left(t\right)=\frac{V_g\left(t\right)}{I_g\left(t\right)};$

The control circuit receives a complex impedance measurement data point and compares the complex impedance measurement data point to a data point in a reference complex impedance characteristic pattern. The control circuit then classifies the complex impedance measurement data point based on a result of the comparison analysis and assigns a state or condition of the end effector based on the result of the comparison analysis. The control circuit estimates the state of the end effector of the ultrasonic device and controls the state of the end effector of the ultrasonic device based on the estimated state.

An electrosurgical instrument is provided that captures, compresses, fuses and cuts tissue between upper and lower jaws connected to pivotably movable handles. The instrument includes a force and over compression regulation mechanism that is configured such that in a clamped configuration, the jaws delivers a gripping force between the first jaw and the second jaw between a predetermined minimum force and a predetermined maximum force.

An instrument may comprise a shaft and an end effector comprising a jaw mechanism coupled to the shaft. The jaw mechanism may comprise a first jaw member and a second jaw member movable relative to one another by pivoting about a pivot axis between an open configuration of the jaw mechanism and a closed configuration of the jaw mechanism. The second jaw member may be rotatable about a roll axis of the second jaw member between at least two orientations, the roll axis of the second jaw member being transverse to the pivot axis. In a first orientation of the at least two orientations, the jaw mechanism is configured to perform a first function. In a second orientation of the at least two orientations, the jaw mechanism is configured to perform a second function differing from the first function.

An electrosurgical instrument (1) includes a first shaft member (110) pivotably coupled to a second shaft member (120), and a trigger (184) disposed on the second shaft member (120). The first and second shaft members (110,120) respectively include first and second handle members (130,140), and first and second jaw members (150,160). The first and second shaft members (110,120) define a longitudinal axis extending through a pivot, and first and second pivot axes that are substantially orthogonal to each other and the longitudinal axis. At least one of the first or second handle members (130,140) is pivotable about the first pivot axis to move the first and second jaw members (150,160) to an open position, a grasping position, or a sealing position. The trigger (184) is movable to pivot at least one of the first or second shaft members (110,120) about the second pivot axis to laterally displace the first and second jaw members (150,160) relative to each other to a cutting position.

Provided is a scissors-type medical treatment tool capable of not only local tissue fixation in an incision/cutting part but also heating on side surfaces of electrodes of a forceps/tweezers type. It has been found out that a tissue part in which tissue is nipped between blades and a tissue part which is brought into abutment against side surfaces of the blades can be heated simultaneously or sequentially by optimizing arrangement of microwave application electrodes and microwave receiver electrodes in a blade pair (in particular, by causing coagulation to be performed evenly on the left and right of the blades), and the present invention has therefore been achieved.

An ultrapolar electrosurgery blade and an ultrapolar electrosurgery pencil. The ultrapolar electrosurgery blade has a non-conductive planar member with opposing planar sides, a cutting end, and an opposite non-cutting end, first active and return electrodes located on one opposing planar side, and second active and return electrodes located on the other opposing planar side.

In an energy control device, a processor detects a gradual decrease start time at which the electric characteristic value in relation to electric energy output to an ultrasonic transducer starts a gradual decrease after a gradual increase. The processor calculates a difference value by subtracting the electric characteristic value from a peak value at gradual decrease start time and calculates an integrated value of the difference value from the gradual decrease start time. The processor executes, based on a fact that the integrated value become greater than a predetermined threshold, at least one of causing to stop or reduce the output of the electric energy to the ultrasonic transducer, and notifying that the integrated value become greater than the predetermined threshold.

A medical device includes a shaft including a central lumen configured to direct a flow of fluid through the shaft, and an electrode positioned at a distal portion of the shaft. The electrode includes an electrode lumen in fluid communication with the central lumen, and the electrode lumen is configured to receive the flow of fluid from the central lumen. The electrode also includes one or more channels angled relative to the electrode lumen, and the one or more channels are in fluid communication with the electrode lumen to receive the flow of fluid from the electrode lumen. The one or more channels are configured to divert the flow of fluid from the electrode lumen toward one or more outlets laterally offset from the electrode lumen.

A method of sealing tissue includes attempting to grasp tissue between first and second jaw members of an end effector assembly of an electrosurgical instrument, attempting to conduct electrosurgical energy between the first and second jaw members, and determining, based on impedance feedback from the electrosurgical energy, whether an error exists. In a case where no error is detected, the method includes implementing a tissue treating algorithm to treat tissue grasped between the first and second jaw members. The tissue treating algorithm includes conducting electrosurgical energy between the first and second jaw members and through tissue grasped therebetween. In a case where an error is detected, the method includes determining, based on additional feedback data, a cause of the error, and outputting an alarm indicating the error and the cause of the error.
