In an example, an electrosurgical device includes a housing defining an interior bore. The electrosurgical device also includes a shaft telescopically moveable in the interior bore of the housing, an electrosurgical blade coupled to the shaft, and a helical conductor coiled around the shaft and configured to supply electrosurgical energy from an electrosurgical generator to the electrosurgical blade.
Surgical lighting must balance various needs of a user: the light must be bright, but not too thermally hot; directed at a target, but not shining elsewhere; be robust, yet compact. Often much of these myriad needs must be accomplished by ever small illumination elements placed into devices requiring ever lower profiles. However, current surgical illumination options require the use of bulky lighting elements if the desire target is to be illuminated or, conversely, use weaker lighting elements for sleeker designs.
An illuminated energy device comprising a handle, an illumination element coupled to the handle and disposed continuously and circumferentially about an electrosurgical tip, the electrosurgical tip at a distal end of the handle. The illumination element is preferably adjustably coupled to the handle, and adjustment of the illumination element moves a distal end of the illumination element closer to or further away from a target such as tissue in a surgical field.
Surgeons may face the difficulty of preoperatively selecting the location for making an incision and intraoperatively identifying and differentiating targeted tissue for removal or for identification so that it is not removed along with neighboring or non-target tissue or so that neighboring or non-target tissue is not nicked, harmed, or removed accidentally. A tissue specific marker can include an aptamer or an affimer configured to bind to a pre-selected target tissue and one or more indicator elements coupled with the aptamer or the affimer. The one or more indicator elements produce a signal thereby allowing identification of the target tissue in a preoperative and operative manner.
An illuminated energy device includes a handle, an optical waveguide coupled to the handle, and an energy tip such as an electrode coupled to the optical waveguide. The optical waveguide is preferably adjustably coupled to the optical waveguide, and adjustment of the optical waveguide moves a distal end of the optical waveguide closer to or further away from a target such as tissue in a surgical field.
A surgical illumination apparatus comprises a fiber optic input, and illuminated surgical instrument, and an optical coupling bracket for coupling the fiber optic input to the illuminated surgical instrument. The coupling bracket comprises an elongate frame having a proximal end, a distal end, and a central channel extending therebetween, wherein the central channel is sized to receive and support optical fibers of the fiber optic input. The proximal end of the bracket is coupled to the fiber optic input, and the distal end of the bracket is coupled to an illumination element of the illuminated surgical instrument. The apparatus may further comprise a shroud disposed around the illumination element that is coupled to the bracket.
A surgical system that illuminates a surgical site using one or more illumination means is powered by radiofrequency energy produced by an electrosurgical generator. Illumination may occur whether or not current is being delivered from an active electrode to target tissue.

An illumination element such as an optical waveguide for illuminating a surgical field in a patient has a light input section, a light transmitting section, and a light output section. The light input section is optically coupled to a proximal section of the light transmitting section and inputs light into the illumination element. The light transmitting section transmits the light preferably by total internal reflection or by other transmission means. The light output section is adjacent a distal section of the light transmitting section which has a light extraction area from which the light exits with an energy density. The light extraction area is large enough to maintain the energy density at a level that prevents melting of the illumination element or burning of the patient, and the light extraction area has a profile that does not interfere with access to the surgical field.

METHODS AND APPARATUS FOR CONTROLLING OPTICAL PROPERTIES OF LIGHT
A surgical instrument for illuminating a surgical field has an optical waveguide for transmitting light by total internal reflection. One or more control elements are disposed on the optical waveguide. The control elements extract light from the optical waveguide and control first and second optical properties of the extracted light Another surgical instrument includes a first and second optical waveguide for transmitting light by total internal reflection. A coupling element is attached to both optical waveguides such that the optical waveguides are movable and pivotable relative to one another.
