Research Facts
A hyfrecator is a low-powered medical apparatus used in electrosurgery on conscious patients, usually in an office setting. It is used to destroy tissue directly, and to stop bleeding during minor surgery. Wikipedia
Used to remove skin lesions, benign and malignant; use discontinued because of the amounts of radio, television and broadcast interference generated by its use (RF1, TV1, BCI)
The word hyfrecator is a portmanteau derived from “high-frequency eradicator.” It was introduced as a brand name for a device introduced in 1940 by the Birtcher Corporation of Los Angeles.[1] Birtcher also trademark registered the name Hyfrecator in 1939, and rights to the registered trademark were acquired by ConMed Corporation when it acquired Birtcher in 1995.

Description
The retractor consists of a stationary handle and moving parts; possibly chest retractor?; the handle is all of one piece, curving at its bottom into a semicircle, and curving at the top into a long oval tongue, slightly concave; there is a long oval slit down most of the handle's length, through which two flat wing-type pieces of metal protrude, securing the moving parts while allowing it to slide up and down; these attachments connect to another, smaller handle that curves into a "Z" shape, away from the main handle; the tip is wide, round, and corrugated to provide a resting place for a thumb; a large, round threaded knob joins the mini-handle, the main handle, and two round, long arms that extend upwards in a slightly curved "V" shape; these arms slide through two short cylinders on either side of the main handle, securing them; at the upper end of each arm, attached by bolts, is a long metal tongue, slightly concave and rounded at both ends; both ends are bent outwards at 90°; when the mini-handle is pushed up, these tongues move upwards and outwards.

Research Facts
A hyfrecator is a low-powered medical apparatus used in electrosurgery on conscious patients, usually in an office setting. It is used to destroy tissue directly, and to stop bleeding during minor surgery.
The word hyfrecator is a portmanteau derived from “high-frequency eradicator.” It was introduced as a brand name for a device introduced in 1940 by the Birtcher Corporation of Los Angeles.[1] Birtcher also trademark registered the name Hyfrecator in 1939, and rights to the registered trademark were acquired by ConMed Corporation when it acquired Birtcher in 1995.
