A surgical forceps includes an end effector assembly including a first jaw member and a second jaw member pivotally engaged with one another. At least one of the first or second jaw member is pivotable between a spaced-apart position and an approximated position. The first jaw member includes first and second surfaces on opposite sides thereof. The first surface is disposed in opposition to the second jaw member. The second surface includes a cutting edge disposed on a proximal portion thereof. The second jaw member includes a proximal flange having first and second raised sidewalls defining a proximal channel therebetween. The proximal channel receives the cutting edge of the first jaw member when the first and second jaw members are in the approximated position.

An electrosurgical device includes jaw members, a thermal cutting element coupled to one of the jaw members. When the jaw members are in an approximated position, power is delivered to the thermal cutting element to maintain the temperature of the thermal cutting element at an operating temperature for cutting sealed tissue grasped between the jaw members. When the jaw members are in the spaced apart position, power is delivered to the thermal cutting element to maintain the temperature of the thermal cutting element at a standby setpoint temperature. In response to a determination of contact between tissue and the thermal cutting element when the jaw members are in the spaced apart position, power is delivered to the thermal cutting element to increase the temperature of the thermal cutting element from the standby setpoint temperature to a cutting setpoint temperature for dissecting tissue.

An electrosurgical system includes jaw members having a cutting element extending therebetween and a generator configured to: provide minimal power to the cutting element to maintain a pre-dissection temperature thereof; sense a change in resistance of the cutting element and ramp up power to a dissection temperature; regulate the temperature of the cutting element by regulating power; and terminate power to the cutting element to allow the cutting element to cool to the pre-dissection temperature before providing power back to the cutting element.

An auxiliary power supply device in which an increase in the size of an entire system including both an auxiliary power supply circuit unit and a sub-power supply circuit unit is able to be curbed is provided. There is provided an auxiliary power supply device configured to be connected to a power supply device, the auxiliary power supply device including: an auxiliary power supply circuit unit configured to supply electric power to the power supply device in a case in which supply of electric power to the power supply device is shut off; and a sub-power supply circuit unit having an input side connected to the power supply device and an output side connected to a load and configured to supply an output voltage to other circuit units in accordance with electric power supplied from the power supply device.

Limiting joint temperature. At least some of the example embodiments are systems including an electrosurgical probe and a high frequency power supply. The electrosurgical probe may include: a shaft with a distal end, a proximal end, and lumen defined within the shaft; an active electrode disposed near the distal end; a return electrode disposed on the shaft; and a temperature sensor disposed on the shaft spaced away from the active electrode and the return electrode, the temperature sensor is electrically insulated from the electrically conductive fluid. The high frequency power supply may be coupled to the active electrode, and configured to provide an electrical energy output between the active electrode and the return electrode.
