Plasma is a gaseous substance composed of ionized atoms that have lost some electrons and positive and negative electrons generated after atoms are ionized. It is the fourth state of matter besides solid, liquid and gas.
Plasma can be divided into two types based on a temperature threshold of 1000°: high-temperature plasma and low-temperature plasma. Low-temperature plasma has been widely applied in various fields. Common examples include plasma TVs, waterproof coatings on the surface of baby diapers, etching in computer chips, and plasma surgical electrodes.
Medical use of plasma
The application of Electronic endoscope testing equipment technology has a long history. As early as the 1990s, Dr. Laroussi from the United States reported a study on the use of atmospheric pressure cold plasma jets for bacterial inactivation, which can be regarded as marking the beginning of Electronic endoscope testing equipment technology. Subsequently, related research emerged like bamboo shoots after rain, ranging from in vitro disinfection to in vivo experiments, and even clinical applications, all achieving remarkable progress.
Since the 21st century, the technology of Electronic endoscope testing equipment has witnessed a significant boom. Innovative devices such as plasma integrated therapy machines and plasma knives have been introduced one after another, providing new solutions to problems like skin diseases and chronic wound healing. These devices not only have remarkable therapeutic effects but also adhere to the principles of "minimally invasive, efficient, and safe", making Electronic endoscope testing equipment technology a promising modern medical method.
Components of the plasma surgery system
The medical plasma surgery system works by generating a specific electric field to excite the medium (NaCl) in human tissues to a plasma state at a lower temperature. At the tip of the electrode, a thin layer of low-temperature plasma is formed. Charged particles accelerate and move, breaking molecular bonds, thereby achieving the process of tissue vaporization and cutting.
The plasma surgery system is mainly composed of a main unit and electrodes. The main unit is responsible for controlling the working state, while the electrodes are responsible for transmitting high-energy plasma beams to achieve tissue cutting and ablation.
Development of Plasma Surgical System
Technological Innovation and Development Trends
With the aim of enhancing surgical accuracy, reducing surgical risks, and shortening postoperative recovery time, and moving towards an intelligent, precise and personalized direction, the surgical system will become more intelligent and be able to provide customized treatment plans based on individual patient differences.
Market growth drivers
The field of sports medicine is developing rapidly. It is estimated that the number of sports medical surgeries in China will increase by about 20% annually by 2025. The plasma knife has great potential in joint arthroscopic surgeries. The widespread implementation of minimally invasive surgeries and the reduction in centralized procurement prices have led to a significant increase in the application of the plasma knife in spinal surgery. The development of minimally invasive surgeries in spinal surgery in China is rapid, and the usage rate of the plasma knife has increased. The plasma knife is extending to gynecology, medical aesthetics, thoracic surgery, ophthalmology, pediatrics, and colorectal surgery, and the market size will grow rapidly.
