An electrosurgical pencil includes a housing having proximal and distal ends, the proximal end adapted to connect to an energy source and the distal end adapted to receive an end effector assembly therein, the end effector assembly defining a surface area along a length thereof. An activation switch is operably associated with the housing and is configured to deliver electrosurgical energy to the end effector assembly upon actuation thereof. An air control valve is operatively coupled to the activation switch and is configured to simultaneously deliver a gas from a gas source to the surface area around the end effector upon actuation of the activation switch. One or more vents are defined in the distal end of the housing and are configured to direct the gas towards the surface area of the end effector.

Cable connection systems allow for an electrosurgical return electrode to be simultaneously connected to multiple ESUs. The cable connection systems can include individual return cables for simultaneous connection to each of the ESUs. The cable connection system can also include a junction that joins, connects, or associates the return cables in a manner that allows for the multiple ESU cables to be electrically connected to the return electrode at a single connection point on the return electrode.

Some implementations include a coaxial bipolar ablation instrument comprising an outer needle and an inner needle inserted into the outer needle. The instrument can also include a first insulating layer disposed between the inner needle and the outer needle, and a second insulating layer disposed over a portion of the outer needle. The instrument can further include a first exposed region of the instrument disposed near a proximate end of the instrument, the first exposed region including a first exposed portion of the inner needle and a first exposed portion of the outer needle, the first exposed region constructed to provide contact to a connector, and a second exposed region of the instrument disposed near a distal end of the instrument, the second exposed region forming the active region of the instrument and including a second exposed portion of the inner needle and a second exposed portion of the outer needle.

The various inventions relate to robotic surgical devices, consoles for operating such surgical devices, operating theaters in which the various devices can be used, insertion systems for inserting and using the surgical devices, and related methods.

A surgical instrument is configured to consist of two separable parts. The first part includes a disposable end effector unit, including an electrosurgical end effector and mechanical drive componentry. The second part includes a reusable electronics unit, containing the RF electronic circuitry of the instrument. A user-releasable complementary interface is provided on each part, allowing the parts to be connected in use. Providing a division of components in this manner improves the sterility of the device, providing easier cleaning of the reusable part of the instrument.

Surgical devices and surgical systems are disclosed. The surgical device can comprise an actuator and a control circuit configured to adjust one or more functions of the surgical device based on a signal from a situationally-aware surgical hub. A surgical system can comprise a screen and a control circuit configured to communicate a priority level of a recommendation to the clinician on the display.

An electromechanical surgical assembly includes a surgical device, an adapter, and a filter. The surgical device includes a connecting portion having a distal facing recess including an electrical plug. The adapter includes a proximal facing cap configured to mate with the recess of the surgical device, the proximal facing cap including an electronic assembly including a plurality of electrical contact pins configured for electrical connection with the electrical plug. The filter is removably positioned within the recess of the surgical device. The plurality of electrical contact pins extend through the filter when the adapter is connected to the surgical device.

An energy delivery system for performing tissue ablation at the distal end of an Electromagnetic Navigation Bronchoscopy (ENB) instrument. The system is insertable through an instrument channel of a steerable instrument cord in an ENB instrument, and comprise a coaxial cable with a radiating tip portion. The tip portion comprises a first conductive element electrically connected to the coaxial cable's inner conductor and a second conductive element electrically isolated from the inner conductor. The conductive elements are arranged to act as: an active electrode and a return electrode for delivering the RF energy into tissue surrounding the radiating tip portion, and an antenna for radiating the microwave energy as a localized microwave field. The system may be arranged to delivery energy according to a predetermined profile comprising interleaving periods of RF and microwave energy or a combination thereof, or a dynamic profile based on detected tissue impedance.

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.

Aspects of the present disclosure are presented for managing simultaneous outputs of surgical instruments. In some aspects, methods are presented for synchronizing the current frequencies. In some aspects, methods are presented for conducting duty cycling of energy outputs of two or more instruments. In some aspects, systems are presented for managing simultaneous monopolar outputs of two or more instruments, including providing a return pad that properly handles both monopolar outputs in some cases.
