Comparative Morphological Effects of Cold-Blade, Electrosurgical, and Plasma Scalpels on Dog Skin

Abstract

The aim of the present study was to evaluate the histological results of the Onemytis® plasma surgery device with Airplasma® technology. We compared the efficacy and the effect on tissues of the new plasma electrocoagulation system with electrosurgery and a scalpel blade. Samples of healthy skin tissue from four dogs that underwent mastectomy were evaluated. Three different incision modes were used, i.e., a cold blade, electrosurgery, and the Onemytis® plasma scalpel were evaluated histologically to assess invasiveness and tissue injuries at different distances from the cutting surface. The histological examinations showed moderate necrosis caused by Onemytis®, compared to the use of the more invasive electrosurgery, which induces thermal damage that extends beyond 1000 µm. Our study shows that the use of the plasma scalpel reduces the extension of the thermal lesion on the skin compared to an electrosurgical scalpel.

Thoracoscopic Assisted PleuralPortTM Application in Seven Dogs Affected by Chronic Pleural Effusion

“…A semicircular skin incision was made with an Airplasma ® (Airplasma ® , Onemytis ® , Alessandria, Italy) device, larger than the port on the pre-determined area (around the 10th intercostal space). A flap was created with Airplasma ® by dissection of the subcutaneous tissue [ 16 , 17 ]. The fenestrated part of the pleural drainage was advanced into the cranial portion of the hemithorax, taking care not to injure the lung parenchyma and avoiding crossing the mediastinum.…”

Enhancing Surgical Tool Performance with Alumina-Based Coatings: An Engineering Analysis

“…Figure 1 shows the system under investigation, the Oneyonis ® medical device(Otech Industries Srl, Alessandria, Italy) for human surgery [9]. Based on AirPlasma ® patented technology (by Otech Industries Srl [10,11]), it is an evolution of similar equipment largely used in veterinary medicine [12,13]. While the surgeon's hand holds a generic tool for external operations (scalpel) in Figure 1a, the other images refer to the probe for endoscopic surgery under investigation.…”

Plasma Scalpels: Devices, Diagnostics, and Applications

“…The plasma scalpel’s thermal effect in tissue mainly depends on the heating rate and the temperature T reached, which, in turn, depends on the plasma power and treatment time [ 6 ]. The plasma scalpel effects on tissue can generally be divided into coagulation (T < 100 °C, slower heating) and cutting (T > 100 °C, faster heating) [ 31 , 32 ]. The higher heat required for the high-intensity heating required for cutting is generated by spark discharges between the electrodes and the tissue.…”
