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 ...

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]
This device is often used with a cast spreader. [2] The patient's skin frequently comes into contact with the cast saw blade without cutting although it can cause lacerations when used over bony prominences. [3] The design enables the saw to cut rigid materials such as plaster or fiberglass.
Spark trails from a cigarette lighter. Ferrocerium (also known in Europe as Auermetall) is a synthetic pyrophoric alloy of mischmetal (cerium, lanthanum, neodymium, other trace lanthanides and some iron – about 95% lanthanides and 5% iron) hardened by blending in oxides of iron and/or magnesium.
The creation of sparks from metals is based on the pyrophoricity of small metal particles, and pyrophoric alloys are made for this purpose. [2] Practical applications include the sparking mechanisms in lighters and various toys, using ferrocerium; starting fires without matches, using a firesteel; the flintlock mechanism in firearms; and spark testing ferrous metals.
[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.
Electrocaloric (EC) devices use the electrocaloric effect, where an electric field causes a reversible temperature change in a material. EC cooling cycles, similar to traditional refrigeration but without harmful refrigerants, involve heating and cooling phases driven by electric fields.
