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 ...
It is a three-sided pyramid which is geometrically self-similar. The popular Berkovich now has a very flat profile, with a total included angle of 142.3° and a half angle of 65.27°, measured from the axis to one of the pyramid flats. This Berkovich tip has the same projected area-to-depth ratio as a Vickers indenter. The original tip shape ...
TIPS is a life-saving procedure in bleeding from esophageal or gastric varices. A randomized study showed that the survival is better if the procedure is done within 72 hours after bleeding. [2] TIPS has shown some promise for people with hepatorenal syndrome. [3] It may also help with ascites. [4]

The fabrication of electrochemically etched sharp tungsten, copper, nickel and molybdenum tips were reported by Muller in 1937. [3] A revolution in sharp tips then occurred, producing a variety of tips with different shapes, sizes, and aspect ratios. They composed of tungsten wire, silicon, diamond and carbon nanotubes with Si-based circuit ...

In peptide synthesis, TIPS is used as a scavenger for peptide groups being removed from the peptide sequence at the global deprotection. TIPS is able to scavenge carbocations formed in the deprotection of a peptide as it can act as a hydride donor in acidic conditions. [1] Silanes may be preferred as scavengers in place of sulfur-based scavengers.
[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.
