Electrosurgical device for cutting tissue

A tool assembly for use with an electrosurgical device for cutting tissue includes a base portion, a return lead, an electrical insulator, a center pin, and an active lead. The center pin extends from the base portion and through a lumen of the electrical insulator. The active lead is securely fixed to the base portion and extends between the base portion and a distal portion of the center pin such that a portion of the active lead extends around the distal portion of the center pin and first and second segments of the active lead are spaced apart from the return lead. Upon activation, electrosurgical energy is transmitted from the active lead through tissue to the return lead to cut tissue in contact with the active lead.

Embodiments include devices and methods configured to fractionally resect skin and/or fat. Fractional resection is applied as a stand-alone procedure in anatomical areas that are off-limits to conventional plastic surgery due to the poor tradeoff between the visibility of the incisional scar and amount of enhancement obtained. Fractional resection is also applied as an adjunct to established plastic surgery procedures such as liposuction, and is employed to significantly reduce the length of incisions required for a particular application. The shortening of incisions has application in both the aesthetic and reconstructive realms of plastic surgery.

ELECTRODE UNIT, TREATMENT SYSTEM AND METHOD FOR OPERATING ELECTRODE UNIT

An electrode unit of the invention includes: an electrode including one end and another end, the other end including a free end; and an electrode supporting portion that supports the one end of the electrode. The electrode is disposed in a second plane that is different from a first plane in which the electrode supporting portion is moved to advance or withdraw when the electrode supporting portion is moved to advance or withdraw in a direction along a longitudinal axis of the electrode supporting portion, and the electrode is supported by the electrode supporting portion via a flexed portion projecting from the first plane to the second plane.

ELECTROSURGICAL HANDHELD DEVICE, AND CONTACT BODY FOR AN ELECTROSURGICAL HANDHELD DEVICE

An electrosurgical handheld device and also a contact body for an electrosurgical handheld device, with which both the required cleanliness and the necessary safety can be obtained. This is achieved by the fact that a contact body for an electrosurgical handheld device for receiving an optical guide and for coupling at least one electrical contact of an electrode instrument of the handheld device has an RF cable, which is fixedly connected to the contact body. By way of this RF cable, an RF voltage can be applied to the electrode instrument via the at least one electrical contact. The other end of the RF cable can be connectable to an RF generator.

SURGICAL PROBE WITH INDEPENDENT ENERGY SOURCES

An energy source is offset from an elongate probe axis with an extension. The amount of offset of the energy source can be controlled by varying an amount of offset of the extension. The energy source rotated and translated at the offset distance to resect tissue. In some embodiments, the probe is configured to receive a second treatment probe comprising a second energy source, in which the second energy source is rotated and translated relative to the first treatment probe, which can improve positional accuracy and stability. The energy source and the extension can be coupled to a linkage to offset the energy source, and to translate and rotate the energy source with varying amounts of offset. The linkage can be coupled to a processor and one or more of the energy source moved in accordance with a treatment profile.
