Piezoelectric Ceramic Transformer

In order to obtain stable cold plasma jet under atmospheric pressure condition, we designed a high-voltage DC power supply based on the principle of multilayer piezoelectric ceramic transformer (MPT). At the same time, we developed a cold plasma jet device that its shape is similar to the gun structure. The total weight of device, including the power supply and the generator, is less than 500 g. In the experiments of argon plasma under atmospheric pressure, current–voltage measurements show that the discharge actually appears periodically pulsed with a frequency of about 30 kHz. The discharge current has a pulse-width that is about 100 ns, while its peak value reaches about 32 mA. The maximum length of the plasma is about 3 cm. The further study showed that the discharge current pulse frequency is determined by the ion drift mechanism.

Plasma Energy

The use of plasma energy has expanded in surgery and medicine. Tumor resection in surgery and endoscopy has incorporated the use of a plasma scalpel or catheter for over four decades. A new plasma energy has expanded the tools in surgery: Cold Atmospheric Plasma (CAP). A cold plasma generator and handpiece are required to deliver the CAP energy. The authors evaluated a new Cold Plasma Jet System. The Cold Plasma Jet System consists of a USMI Cold Plasma Conversion Unit, Canady Helios Cold Plasma® Scalpel, and the Canady Plasma® Scalpel in Hybrid and Argon Plasma Coagulation (APC) modes. This plasma surgical system is designed to remove the target tumor with minimal blood loss and subsequently spray the local area with cold plasma. In this study, various operational parameters of the Canady Plasma® Scalpels were tested on ex vivo normal porcine liver tissue. These conditions included various gas flow rates (1.0, 3.0, 5.0 L/min), powers (20, 40, 60 P), and treatment durations (30, 60, 90, 120 s) with argon and helium gases. Plasma length, tissue temperature changes, and depth and eschar injury magnitude measurements resulting from treatment were taken into consideration in the comparison of the scalpels. The authors report that a new cold plasma jet technology does not produce any thermal damage to normal tissue.
