Application Prospect of Monopolar Low-temperature Plasma Knife in Oral and Maxillofacial Surgery

Oral and maxillofacial surgery is primarily responsible for the treatment of oral and maxillofacial tumors, jaw fractures, maxillary sinusitis, and other temporomandibular joint diseases using surgical techniques. With improvements in living conditions and dietary changes, the demand for diagnosis and treatment in oral and maxillofacial surgery has been steadily increasing. Simultaneously, both patients and healthcare providers have higher expectations for intraoperative effectiveness and postoperative recovery. With the advancement of technology, surgical knives in oral and maxillofacial surgery have gradually transitioned from traditional physical blades to high-frequency electric scalpels. However, high-frequency electric scalpels have drawbacks, including substantial tissue damage, the generation of intraoperative smoke, electrode adhesion, imprecise cutting, and reliance on traditional surgical blades. This paper proposes the idea of using a monopolar low-temperature plasma knife in oral and maxillofacial surgery, with a focus on research utilizing the monopolar low-temperature plasma surgical system produced by Jingyi Medical (Host Model: PSG-60A; Electrode Model: PS-01) as an example. This equipment disrupts tissue molecular bonds through the low-temperature plasma layer formed around the knife tip, allowing for tissue cutting and separation. This approach significantly reduces tissue damage compared to traditional surgical blades and high-frequency electric scalpels, while also simplifying surgical procedures, improving cutting precision, and enhancing postoperative recovery. Through this research, it can be observed that the monopolar low-temperature plasma knife has significant potential for widespread application in oral and maxillofacial surgery.
