Urology Resectoscope Bipolar Low Temperature Cool Plasma Electrosurgical Unit
Cool plasma technology is also called cool plasma ablation because it adopts the same energy emitting methods as the traditional RF generator. However, instead of using thermal energy to create coagulation necrosis of body tissues as the working principle of traditional RF, cool plasma uses high-speed kinetic energy of plasma to create tissues pyrolysis and vaporization directly.
Compared with TURP (Transurethral resection of the prostate), the advantages of cool plasma electrosurgical unit are low operation temperature, less thermal damage, less pain, and quick recovery, etc. It can also avoid transurethral resection of prostate syndrome. And current doesn't pass through the body which helps reduce the obturator nerve reflex.
Technical Principle
Under the low frequency electric field, a thin layer of plasma about 100 μm thick was formed around the electrode through normal saline. The plasma-thin layer consists of highly ionized particles with sufficient kinetic energy to break the organic molecular bonds of the target tissue and vaporize it. Normal saline was used as washing solution to perform tissue cutting and coagulation, so that the body does not need to follow negative electrode plate, to avoid the occurrence of electrotomy syndrome TURS, and to improve the safety of surgery.
Product Features
- Avoid the occurrence of electrotomy syndrome TURS.
- Reduce the risk of obturator nerve reflex.
- Low temperature cutting, low tissue damage.
- Vaporization cracking, no carbonization, no smoke.
Technology Advantages
1) 40-70ºC Low Temperature: Compared with ordinary electrosection, low temperature plasma has limited heat penetration, less tissue damage, reduce the possibility of secondary bleeding after operation, small amount of bleeding during operation and fast recovery time.
2) Normal Saline as Flushing Solution: ECO Cool Plasma Elestrosurgical System uses normal saline as the flushing solution. Because saline is isotonic with the human body's internal environment, it can prevent the large amount of flushing fluid from being absorbed by the human body, resulting in prostatectomy syndrome (water poisoning, low sodium).
3) Bipolar Electrode: The energy loop is completed between the two poles. It does not need the negative plate and does not pass through the adjacent organs and tissues, reducing the risk of obturator nerve reflex and preventing the prostate capsule from being cut through.
Frequently Asked Questions
Q1: What is the main difference between Cool Plasma and traditional RF?
Traditional RF uses thermal energy to create coagulation necrosis, while cool plasma utilizes high-speed kinetic energy to achieve tissue pyrolysis and vaporization directly at lower temperatures.
Q2: Why is this technology considered safer for prostate surgery?
By using normal saline as a flushing solution and a bipolar energy loop, it prevents transurethral resection of prostate syndrome (TURS) and reduces the risk of obturator nerve reflex.
Q3: What are the typical operating temperatures of this unit?
The system operates at a low temperature range of 40-70ºC, with tissue ablation typically occurring at ≤54ºC, which significantly reduces thermal damage to surrounding healthy tissue.
Q4: In which departments can this electrosurgical unit be applied?
It is primarily designed for use in Urology, Andrology, and Anorectology departments for various surgical procedures.
Q5: Does the patient require a negative electrode plate?
No, because it uses a bipolar electrode system, the energy loop is completed between the two poles of the instrument, eliminating the need for a patient return electrode plate.
Q6: What are the benefits regarding post-operative recovery?
Due to the limited heat penetration and minimal tissue damage, patients usually experience less pain, a reduced risk of secondary bleeding, and a faster overall recovery time compared to traditional methods.
