Systems and related methods for identifying and/or ablating targeted nerves are provided. A probe with stimulating electrodes and/or ablation members are provided. The probe may be inserted into a nasal cavity and current may be introduced through the electrodes to stimulate a targeted area. The response to stimulation may be used to identify the targeted nerve. Once identified, the ablation member may ablate the targeted nerve.

Disclosed herein are tissue ablation devices and methods. The device comprises a sheath comprising a distal end that is positionable at an ablation site in the tissue, a proximal end and a lumen extending therebetween. The device also comprises one or more electrodes that are advanceable and retractable through the lumen, wherein a distal portion of the one or more electrodes is deployable into a tissue ablating configuration from the distal end of the sheath upon advancement, and the one or more electrodes are removable from the lumen via the proximal end of the sheath upon retraction, whereupon the lumen becomes vacated. The sheath is configured for a surgical material to traverse the vacated lumen for delivery from the distal end of the sheath into the tissue.

An electrosurgical blade (900) configured to couple to an RF electrosurgical instrument (100). The electrosurgical blade (900) includes a proximal portion (900a) configured to couple to a blade receptacle (104) of an RF electrosurgical instrument (100), a coagulation section (920) extending distally from the proximal portion (900a), a blade edge (940) defined around a periphery of the electrosurgical blade (900), and a ramped surface (930) extending between the coagulation section (920) and the blade edge (940). The blade edge (940) includes a right-angled tip (944) and is defined by a first side (941) extending longitudinally, a second side (942) extending longitudinally and having a curved portion (942c), and a distal side (943) extending laterally.

An arthroscopy system includes both a motorized handpiece and a detachable probe. The motorized handpiece includes a rotating driver which is configured to engage a rotatable drive coupling within a hub of the probe. The probe has a shaft with an articulating distal region, and the rotatable drive coupling is configured to convert the rotary motion of the rotating driver to an articulating motion within the articulating region of the probe.

A medical instrument sheath including an elongated hollow tube having a wall comprised of polymeric material; and at least one electrical lead embedded inside the wall, wherein the at least one electrical lead is configured to be connected with a respective electrode disposed in a member located inside the sheath and extending from a distal end of the sheath.

A bipolar forceps includes a mechanical forceps including first and second shafts each having a jaw member extending from a distal end thereof and a handle disposed at a proximal end thereof for effecting movement of the jaw members relative to one another about a pivot. A disposable housing is configured to releasably couple to at least one of the shafts and an electrode assembly is configured to releasably couple to the disposable housing. The electrode assembly includes electrodes releasably coupleable to the jaw members. At least one of the electrodes includes a knife channel configured to receive a knife blade therethrough to cut tissue grasped between the jaw members. An actuation mechanism is configured to selectively advance the knife blade through the knife channel to cut tissue.

A medical device includes a shaft including a lumen configured to direct a flow of fluid through the shaft and an electrode. A proximal end of the electrode and a distal end of the shaft form a coupling configured to releasably couple the proximal end of the electrode with the distal end of the shaft. When the proximal end of the electrode is coupled to the distal end of the shaft, fluid delivered through the lumen is emitted from the electrode.

The present disclosure relates to an electrosurgical instrument, configured to be releasably connected to a hand-piece. The electrosurgical instrument comprises an elongate shaft, an end effector at a distal end of the elongate shaft, and an electrical connector interface. The electrical connector interface has at least one female electrical socket configured to receive in use at least one male electrical pin of the hand-piece. Prior to first use, the at least one female electrical socket is sealed from an exterior of the electrosurgical instrument by a pierceable sealing layer. The sealing layer is configured to be pierced by the at least one male electrical pins on first use. A further aspect of the present disclosure relates to an electrosurgical system comprising the electrosurgical instrument, the hand-piece and an electrosurgical generator.

Disclosed herein are various embodiments of electrosurgical devices. In one embodiment a removable tip for use with an electrosurgical tool comprises a first tip member having a proximal end and a distal end; a second tip member having a proximal end and a distal end; an actuator coupled to the first tip member and the second tip member, the actuator for moving the first and second tip members between a closed position where the distal end of the first tip member and the distal end of the second tip member are proximate one another, and an open position where the distal end of the first tip member and the distal end of the second tip member are separated by a distance from one another; and an insertion member coupled with the proximal ends of the tip members for inserting the removable tip within an opening in the electrosurgical tool.

An HF surgical instrument includes two instrument branches movable toward each other into a closing position. Each branch is equipped with at least one electrode and can be supplied with electric power from a power source. The HF instrument includes a separately configured bridge which is connectable to the power source via at least one electric connection or at least one electric line and includes at least one electrically conductive contact point for supplying the at least one electrode with electric power. The bridge can be introduced to at least one of the two branches so that the at least one contact point is electrically contacted by the at least one electrode. A method of assembling a HF surgical instrument includes equipping two instrument branches with at least one electrode.
