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 ...

[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.
Cauterization (or cauterisation, or cautery) is a medical practice or technique of burning a part of a body to remove or close off a part of it. It destroys some tissue in an attempt to mitigate bleeding and damage, remove an undesired growth, or minimize other potential medical harm, such as infections when antibiotics are unavailable.
Some sources [9] insist that electrosurgery be applied to surgery accomplished by high-frequency alternating current (AC) cutting, and that "electrocautery" be used only for the practice of cauterization with heated nichrome wires powered by direct current (DC), as in the handheld battery-operated portable cautery tools.
The CONMED Corporation is a publicly traded American manufacturer of medical equipment, primarily orthopedic, endoscopy, and general surgical tools. [2] In 2021, orthopedics made up $550 million of its revenue. [3]
A harmonic scalpel cuts via vibration. The scalpel surface itself cuts through tissue by vibrating in the range of 55,500 Hz. The high frequency vibration of tissue molecules generates stress and friction in tissue, which generates heat and causes protein denaturation.
Cherry angioma, also called cherry hemangioma [1] or Campbell de Morgan Spot, [2] is a small bright red dome-shaped bump on the skin. [3] It ranges between 0.5 – 6 mm in diameter and usually several are present, typically on the chest and arms, and increasing in number with age.
