The hyfrecator does not require a dispersive return pad, referred-to in the electrosurgery field as a "ground pad," or "patient plate," because the hyfrecator can pass a very low-powered current between forceps tips via bipolar output, or pass an A.C. current between one pointed metal electrode probe and the patient, with the patient's self ...
One example of such a machine is called a hyfrecator. This term began in 1940 as a Birtcher Corporation brand name Hyfrecator for "High Frequency Eradicator", but now serves generically to describe a general class of single-electrode, non-isolated (earth-referenced) low-powered electrosurgical machines intended mainly for office use. An ...

An early popular American reference to the turbo encabulator appeared in an article by New York lawyer Bernard Salwen in the April 15, 1946, issue of Time magazine. Part of Salwen's job was to review technical ...
In 2021, orthopedics made up $550 million of its revenue. [3] It is part of the S&P 600. It has manufacturing facilities in the United States and Mexico, and sales and distribution offices internationally. [1] [4] Products made by CONMED include the Hyfrecator electrosurgical generator [5] and insufflation systems. [6] [7]
[2] [3] [4] The scraping is then paused while an electrosurgical device like a hyfrecator is used next. Electrocoagulation (electrodesiccation) is performed over the raw surgical ulcer to denature a layer of the dermis and the curette is used again over the surgical ulcer to remove denatured dermis down to living tissue.

Elektrische Gipssäge, by Ortopedia, Kiel, Germany. A cast saw is an oscillating saw used to remove orthopedic casts.Instead of a rotating blade, cast saws use a sharp, small-toothed blade rapidly oscillating or vibrating back and forth over a minimal angle to cut material and are therefore not circular saws.

A typical TMR device consists of two layers of ferromagnetic materials separated by a thin tunnel barrier (~2 nm) made of a multiferroic thin film. [46] In such a device, spin transport across the barrier can be electrically tuned. In another configuration, a multiferroic layer can be used as the exchange bias pinning layer.
