A medical device includes a shaft including a distal end including a passive electrode that defines a central opening extending through the passive electrode, and an active electrode within the central opening. The active electrode is movable between at least an extended position in which the active electrode does not contact the passive electrode, and a retracted position in which the active electrode contacts the passive electrode.

Various handheld cauterization device and/or system embodiments having safety features or components incorporated therein. In certain implementations, the device can be a retractable and deployable safety shield sized to receive any known handheld cauterization device. According to other embodiments, the device can be a handheld cauterization device with a retractable and deployable cauterization tip or a retractable and deployable safety shield.

Methods and devices for treating nasal airways are provided. Such devices and methods may improve airflow through an internal and/or external nasal valve, and comprise the use of mechanical re-shaping, energy application and other treatments to modify the shape, structure, and/or air flow characteristics of an internal nasal valve, an external nasal valve or other nasal airways.

A surgical instrument with a shaft is constructed as a hollow tube and has a longitudinal axis, proximal and distal ends and a metal wire having a first end section, a shaft section and a working section. The first end section is arranged in the area of the proximal end of the shaft or is guided out of the shaft on the proximal end. The shaft section is guided in the hollow tube and the wire is arranged such that it can move along the longitudinal axis of the shaft into a first position of the working section on the distal end projecting out of the shaft and into a second position of the working section within the shaft. The instrument is constructed as a bipolar instrument, wherein the metal wire is part of a first electrode and a second electrode is arranged in some sections on the shaft.

Disclosed herein are methods and devices for the treatment of cellulite. The methods comprise cutting the septae connecting the dermis from the underlying fascia, reducing the appearance of dimples and applying a patch to the skin over the cut septae to hold in place or remodel the skin to allow it to heal in the desired shape and to minimize the recurrence of dimples.

A handheld electrosurgical instrument is disclosed, which comprises an upper lobe and a lower lobe, which join at and extend from a narrow neck region substantially perpendicular to one another. The instrument typically includes a surgical tool extending from a distal portion of the upper lobe. The tool may be modular, and the instrument may accommodate any of a plurality of different types and configurations of surgical tools.

An electrosurgical smoke evacuation pencil includes a handle housing having a proximal end portion and a distal end portion, the handle housing defining a lumen therethrough, a nozzle in fluid communication with the lumen, a pressure sensor configured to sense a vacuum pressure at the nozzle, a connector coupled to the distal end portion of the handle housing, the connector configured to couple to a suction source, and an electrode configured to couple to a source of electrosurgical energy.

A method for adjusting the operation of a surgical instrument using machine learning in a surgical suite is disclosed.

Disclosed embodiments include apparatuses, systems, and methods for positioning electrodes within a body. In an illustrative embodiment, a control handle is selectively engageable with primary and secondary actuators respectively coupled with primary and secondary electrodes. At a first position, the primary and secondary actuators are movably engaged to move in concert to a second position where distal ends of the electrodes extend into a target region. At the second position, the control handle is engaged with the secondary actuator and movable independently of the primary actuator in a first direction to a third position where the distal end of the secondary electrode extends beyond the distal end of the primary electrode. At the third position, the control handle is movably engaged with the primary actuator and movable independently of the secondary actuator in a second direction to a fourth position to partially retract the distal end of the primary electrode.

Disclosed herein is a surgical navigation instrument having a temperature sensor. The surgical navigation instrument can easily perform an autoclave action to remove microorganisms using saturated steam with respect to a part which can be contaminated during treatment, and enhance convenience in replacement of a grip part and the electrodes of the handpiece which are consumables, since a handpiece and electrodes are detachably screw-coupled with each other.
