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 ...
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]
[1] [2] As it is three-sided, it is easier to grind these tips to a sharp point and so is more readily employed for nanoindentation tests. It is typically used to measure bulk materials and films greater than 100 nanometres (3.9 × 10 −6 in) thick.

CNT tips are also used in tapping-mode Scanning Force Microscopy (SFM), which is a technique where a tip taps a surface by a cantilever driven near resonant frequency of the cantilever. The CNT probe tips fabricated using CVD technique can be used for imaging of biological macromolecules, [86] semiconductor [35] and chemical structure. [32]
[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.
While glass and sharp plastic are considered sharps waste, their handling methods can vary. Glass items which have been contaminated with a biohazardous material are treated with the same concern as needles and blades, even if unbroken. If glass is contaminated, it is still often treated as a sharp, because it can break during the disposal process.
A spitzer bullet (from German: Spitzgeschoss, "point shot") is a munitions term, primarily regarding fully-powered and intermediate small-arms ammunition, describing bullets featuring an aerodynamically pointed nose shape, called a spire point, sometimes combined with a tapered base, called a boat tail (then a spitzer boat-tail bullet), in order to reduce drag and obtain a lower drag ...
