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.

The present invention relates to a skin treatment device including a handpiece and a needle tip enabling to be coupled to the handpiece, wherein as the needle tip is mounted on the distal end of the handpiece, electrical connection with the handpiece can be made stably, and even if the needle module built in the needle tip performs linear reciprocating motions of extension and retraction by the driving device provided in the handpiece, the motion trackable connector provided in the needle tip can stably keep the electrical connection between the handpiece and the needle tip.

Systems described herein include a two-tip handpiece that delivers current from two sources at two different frequencies. Signals at different frequencies are absorbed differently in the body. Accordingly, both monopolar and bipolar systems using this two-tip handpiece and dual-frequency signal can detect impedance (or other frequency-dependent characteristics) of the target tissue at the tips while delivering treatment, which was not possible or practical using conventional systems.

A device and method for cutting or ablating tissue in a human or veterinary patient includes an elongate probe having a distal end, a tissue cutting or ablating apparatus located adjacent within the distal end, and a tissue protector extending from the distal end. The protector generally has a first side and a second side and the tissue cutting or ablating apparatus is located adjacent to the first side thereof. The distal end is structured to be advanceable into tissue or otherwise placed and positioned within the patient's body such that tissue adjacent to the first side of the protector is cut away or ablated by the tissue cutting or ablation apparatus while tissue that is adjacent to the second side of the protector is not substantially damaged by the tissue cutting or ablating apparatus.

An ablation device including a body having a lumen for receiving a distal end of an endoscope, a cover portion extending from a side of the body, the cover portion defining a recess between the cover portion and the body, and an electrode platform having at least one electrode positioned thereon, the electrode platform movable between a covered position, where the at least one electrode is covered by the cover portion, and an exposed position, where the at least one electrode is at least partially exposed beyond the cover portion. At least one vacuum port is formed in the electrode platform.

Disclosed herein are a surgical navigation instrument having a needle electrode depth adjusting structure for detecting impedance and a high frequency energy control method using the same. The present invention can detect impedance of tissues while applying a pilot signal to an electrode of a high frequency needle according to impedance conditions of the tissues to detect impedance of the tissues, and determine an applied amount of high frequency energy output to high frequency needles according to the detected impedance, thereby reducing patients' pains, maximizing treatment effect, and reducing treatment time according to high frequency energy applied to various depths at the same treatment point when performing a surgical procedure with the same or different treatment parameters according to disease symptoms while selecting the insertion number of high frequency needles, which can be adjusted in penetration depth, into the skin.

An auxiliary return system for use with a bipolar electrosurgical device includes a tissue guard defining an open proximal end, an open distal end, and a lumen extending therethrough between the open proximal end and the open distal end. A ground plate is disposed along an inner peripheral surface of the lumen and is operably coupled to a first end of a ground wire extending from the tissue guard. A coupling is included having a bore defined therein for receiving a cable from an electrosurgical device therethrough, the cable including active and ground leads. The coupling has a flange extending therefrom defining a receptacle therein configured to operably receive a plug connected to a second end of the ground wire. The receptacle is configured to provide electrical continuity between the ground lead disposed within the cable and the plug coupled to the ground wire which, in turn, provides electrical continuity to the ground plate.

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.

A cautery pen tip accessory cover comprises a cylindrical member that can receive a cautery pen in a first end and the tip of the cautery pen can extend from a second opposite end when the cover is in a retracted configuration. The cylindrical member has an opened lateral exposure that allows the feel of the cautery pen therethrough. A cover exposure opening in the cylindrical member to provide access to a trigger of the cautery pen when the cautery pen tip cover is in the retracted configuration. A resilient member urges the cautery pen tip cover to the non-retracted configuration where access to the cautery pen trigger is prevented. The cylindrical member is easily retracted by a finger ring configured permanently into the cylindrical member, allowing easy retraction of the cover by the operator squeezing the cover to a resistance bar stabilization system accessory configured over the cautery pen.

An elongate electrode is configured to flex and generate plasma to incise tissue. An electrical energy source operatively coupled to the electrode is configured to provide electrical energy to the electrode to generate the plasma. A tensioning element is operatively coupled to the elongate electrode. The tensioning element can be configured to provide tension to the elongate electrode to allow the elongate electrode to flex in response to the elongate electrode engaging the tissue and generating the plasma. The tensioning element operatively coupled to the flexible elongate electrode may allow for the use of a small diameter electrode, such as a 5 μm to 20 μm diameter electrode, which can allow narrow incisions to be formed with decreased tissue damage. In some embodiments, the tensioning of the electrode allows the electrode to more accurately incise tissue by decreasing variations in the position of the electrode along the incision path.
