Patent number: 11903630Abstract: An electrosurgical apparatus with a retractable blade for use in cold plasma applications, electrosurgical cutting and mechanical cutting is provided. The electrosurgical apparatus employs a tip of the retractable blade as a sharp conductive point to generate a plasma beam or discharge. When the blade is retracted within the electrosurgical apparatus, it is electrically energized while an inert gas flows over it, producing a cold plasma discharge. In the de-energized state, the blade is advanced and used as a traditional, mechanical surgical blade.Type: GrantFiled: November 23, 2020Date of Patent: February 20, 2024Assignee: Apyx Medical CorporationInventors: Jeffrey C.

Patent number: 9763724Abstract: Systems and methods for discriminating between various gases, e.g., argon and helium, for enhanced safety of medical devices are provided. The present disclosure may take the form of a dedicated-use embodiment where a specific gas, helium for example, is expected, and an enabling or “Go” signal is issued when that gas is detected, or an inhibitory or “No-Go” signal when a gas is present that is not identified as helium. Alternately, a control line or input command can be used to select between helium and argon as the expected gas and then issue the appropriate “Go/No-Go” signal, depending on which gas is identified.Type: GrantFiled: October 21, 2016Date of Patent: September 19, 2017Assignee: Bovie Medical CorporationInventors: Gregory A.

Patent number: 9681907Abstract: The present disclosure relates to an electrosurgical apparatus to generate a dual plasma stream to perform electrosurgery on a surgical site on a patient. The apparatus and method of the present disclosure generates a hot gas jet to a surgical site by generating two plasma beams that are electrically up to 180 degrees out of phase from each other. Since each beam uses the other beam to establish plasma currents at a load, the combined dual plasma stream can be used on non-conductive surfaces, e.g., a tissue at the surgical site. Furthermore, by applying different flow rates to the plasma beams, various scanning effects by the hot gas jet can be achieved.Type: GrantFiled: June 27, 2014Date of Patent: June 20, 2017Assignee: Bovie Medical CorporationInventors: Gregory A. Konesky, Borislav S. Simeonov
