Minimally Invasive Beaded Electrosurgical Dissectors, Basic Science, and Pilot Studies

Abstract

DOI: 10.1093/asjof/ojae034; Aesthetic Surgery Journal Open Forum, 6, 0, 2024-05-06.; Abstract: Background: Minimally invasive beaded electrosurgical dissectors (“BEED devices”) provide simultaneous sharp dissection, blunt dissection, and electrosurgical coagulation while performing 100 cm2 porcine tissue plane dissections in 0.8 to 3 min with minimal bleeding and no perforations. Objectives: The aim of the study was to report the basic science and potential clinical applications and to video document the speed and quality of planar dissections in in vivo and ex vivo porcine models with thermal damage quantified by thermal and histopathologic measurements. Additionally, in vivo porcine specimens were followed for 90 days to show whether adverse events occurred on a gross or macroscopic basis, as evidenced by photography, videography, physical examination, and dual ultrasonography. Methods: Ex vivo porcine models were subjected to 20, 30, and 50 W in single-stroke passages with BEED d
