Electrosurgery is a technology developed over the last few years and has become a very important tool in modern surgery. Most of the equipment is considered safe, although there are risks related to its use. Several lesions may be caused by electrocautery, and burns are the most common and feared. We report two cases of burns related to use of electrocautery and promote a literature review, bec...

Electric discharge utilized for electrosurgery is studied by means of a recently developed method for the diagnostics of small-size atmospheric plasma objects based on Rayleigh scattering of microwaves on the plasma volume. Evolution of the plasma parameters in the near-electrode sheaths and in the positive column is measured and analyzed. It is found that the electrosurgical system produces a ...

Context Electrosurgery offers many unique advantages such as hemostasis and precise tissue cutting; however, there are a number of disadvantages including thermal injury and delayed wound healing. Aims The aim of the present study was to compare the outcomes of incisions made by Colorado® microdissection needle, electrosurgery tip, and surgical blade during periodontal surgery. Settings and...

The purpose of this study was to investigate the effect of an immunomodulatory protein (Ling Zhi-8, LZ-8) on wound healing in rat liver tissues after monopolar electrosurgery. Animals were sacrificed for evaluations at 0, 3, 7, and 28 days postoperatively. It was found that the wound with the LZ-8 treatment significantly increases wound healing. Western blot analysis clearly indicated that the ...

The benefits of electrosurgery have been acknowledged since the early 1920s, and nowadays more than 80% of surgical procedures involve devices that apply energy to tissues. Despite its widespread use, it is currently unknown how the operator's choices with regard to instrument selection and application technique are related to complications. As such, the manner in which electrosurgery is applie...

While physics-based modeling of electrosurgical procedures is essential for most laparoscopic simulation systems, we present such a system for the first time in this paper. We have implemented a physics-based model of electrosurgery to control the temperature distribution on the tissue as a function of time. Then, we evaluate the algorithm within a complete graphics-haptics-physics-based system.
