"Plasma" is a modern physics that began to emerge in the 1950s. It is a new discipline that has developed rapidly. Its low-temperature plasma, cold plasma, and hot plasma technologies have been widely used in many fields such as medicine, electronics, industry, military, and daily life. As a high-tech technology, low-temperature plasma has attracted more and more attention from experts and scholars at home and abroad due to its outstanding contributions to environmental protection and medicine. Plasma electric scalpels have also come into being. Low-temperature plasma ablation technology has also attracted much attention. Compared with traditional surgery, low-temperature plasma ablation technology has the characteristics of minimally invasive, precise, convenient, and safe. SMD Medical Technology was invited to develop a new generation of plasma energy platform.

Existing technology is insufficient

Traditional electric scalpel is an electrosurgical instrument that replaces mechanical scalpels and is used for tissue cutting. It uses the high-voltage current generated at the end of the effective electrode to heat human tissue when it comes into contact with the human body, thereby achieving the purpose of separating and condensing human tissue.

1. If the traditional electric scalpel is improperly operated or the wire contact is poor, there is a risk of electric shock to the operator.

2. Traditional electric knives require positive and negative electrodes. If the electrodes and placement positions are not properly selected, it will cause electric burns to the patient and liquefaction of wound fat;

3. When cutting with traditional electric knives, the temperature cannot be controlled. Too high a temperature will easily cause the tissue to char and smoke, affecting the operator's vision, thus affecting the cutting effect;

4. In micro-surgery, compared with plasma technology, traditional electric knives are too damaging, affecting the patient's postoperative recovery effect;

Main research and development direction

The working principle of the plasma knife is to form a thin layer of plasma between the electrode and the tissue. The ions in this thin layer are accelerated by the electric field and transfer energy to the tissue. At a high temperature of 40 degrees Celsius to 70 degrees Celsius, the bonds between cells are opened, and the cells in the target tissue are decomposed into carbohydrates and oxides, resulting in liquefaction and ablation of the diseased tissue. This is the so-called plasma, thereby achieving the volume reduction effect of the target tissue.

Main innovations

1. Structure: Bipolar design is adopted to reduce the risk of patient burns.

2. Technology: Plasma technology is used to achieve minimally invasive effects.

3. Performance:

1). Power detection circuit is used to achieve high-precision power detection with detection accuracy of ±2%.

2). Low-pass filter circuit is used to achieve output of pure sine wave waveform.

3). Standard output frequency is used to achieve accuracy of ±5%.

4. Function:

1). Real-time voice and sound and light alarm are used to increase the safety of equipment use.

2). Dual system detection is added to increase system stability;

Expected effect

Project results:

1) Technical results: After the completion of this project, a new process will be produced by rapid method and a pilot production line will be formed;

2) Intellectual property results: 5 patents are applied for project-related technologies and processes, including 1 invention, 2 utility model patents, 1 design patent, and 1 software copyright.

Economic benefits

Plasma electrosurgical knife is a key equipment in the current electrosurgical knife field. The equipment currently used in China mainly relies on imports, and most of the imported equipment costs are around 1 million RMB. SmartVein Medical Technology starts from the R&D end through proofing, type inspection, product registration, and mass production, fully integrating resource advantages to save customers a lot of costs. The cost of the equipment produced according to the research results of this project is less than half of that of foreign equipment, which indirectly reduces the medical expenses of patients and generates considerable social value.
