An apparatus includes a shaft assembly, first and second electrode assemblies, and a controller. The shaft assembly is configured to fit in a nasal cavity of a patient. The first and second electrode assemblies are at the distal end of the shaft assembly. The second electrode assembly includes a stimulus electrode and a sensing electrode. The stimulus and sensing electrodes are positioned on opposing lateral sides in relation to the longitudinal axis of the shaft assembly. The controller is operable to generate an electrical signal to perform one or both of tissue ablation or denervation of a targeted nerve via the first electrode assembly, generate an electrical stimulus signal to stimulate the targeted nerve via the stimulus electrode of the second electrode assembly, and process a response signal received from the targeted nerve via the sensing electrode of the second electrode assembly.

An evacuation system and method for removing and/or treating gaseous and/or particulate byproducts of surgical procedures includes an end effector such as a side vent trocar, an operating room tower or the equivalent, a disposal vessel, a vacuum source and optionally a filter. The end effector may be coupled to the tower by a conduit, the tower may be coupled to the collection tank by a conduit, and the collection tank may be coupled to the vacuum source. Gaseous and/or particulate byproducts may flow from the surgical site through the trocar, conduits, tower tank and filter, and the flow may be regulated at least in part by the components of the system.

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

Surgical systems can include evacuation systems for evacuating smoke, fluid, and/or particulates from a surgical site. A surgical evacuation system can be intelligent and may include one or more sensors for detecting one or more properties of the surgical system, evacuation system, surgical procedure, surgical site, and/or patient tissue, for example.

Embodiments provide a telescopic structure for an electrotome capable of evacuating smoke, including an electrotome pencil body. The electrotome pencil body is hollow inside and provided with an opening end at one end; the opening end of the electrotome pencil body is provided with a limit connection part. The limit connection part is sleeved with a collar; an elastic limiter is provided between the limit connection part and the collar. The telescopic structure for an electrotome capable of evacuating smoke further includes a channel that penetrates the collar and the elastic limiter in sequence and communicates with the inside of the electrotome pencil body. The telescopic structure for the electrotome capable of evacuating smoke enables the electrotome to adjust the length of the electrotome with one hand during use, which is more convenient in use and more convenient in operation.

A method of spectrometric analysis comprises obtaining one or more sample spectra for an aerosol, smoke or vapour sample. The one or more sample spectra are subjected to pre-processing and then multivariate and/or library based analysis so as to classify the aerosol, smoke or vapour sample. The results of the analysis are used for various surgical or non-surgical applications.

A method for producing a surgical instrument is disclosed. The method comprises obtaining a handle, wherein the handle comprises a distal end comprising a shaft interface surface and a first set of magnetic elements. The method further comprises obtaining a shaft, wherein the shaft comprises a proximal end comprising a handle interface surface, a second set of magnetic elements, and a third set of magnetic elements. The method further comprises attaching the shaft to the handle, wherein the shaft interface surface is configured to engage the shaft at the handle interface surface, wherein an attractive magnetic force is configured to pull the handle towards the shaft when the first set of magnetic elements interact with the second magnetic elements, and wherein a repulsive magnetic force is configured to repel the handle from the shaft when the first set of magnetic elements interacts with the third set of magnetic elements.

An improved multifunction cable for use in an operating room avoids the usual tangle of wires and tubes can be a significant hazard. The cable comes pre-sterilized with a number of wires and tubes pre-installed in a protective housing making it easy to conduct myriad wires and tubes from one region of the operating room to another without any possibility of tangling or violation of sterility. At the sterile end of the cable a special terminus acts as a holder to keep the various operating instrument organized. The terminus is designed to accept a special smoke evacuating monopolar electrosurgery instrument.

A return pad of an electrosurgical system is disclosed. The return pad includes a plurality of conductive members and a plurality of sensing devices. The conductive members are configured to receive radio frequency current applied to a patient. The sensing devices are configured to detect at least one of the following: a nerve control signal applied to the patient; and a movement of an anatomical feature of the patient resulting from application of the nerve control signal.

Example electrosurgical devices and systems are disclosed. An example electrosurgical device includes a body, an electrosurgical electrode secured to the body, the electrosurgical electrode including a distal tip. The electrosurgical device also includes a shroud translatable relative to the electrosurgical electrode between a first position and a second position, a first magnetic component which is operably connected to the body, and a second magnetic component which is operably connected to the shroud, wherein the first and second magnetic components magnetically interact to releasably maintain the shroud in the first position.
