In the medical field, surgical treatment of many diseases requires the use of high-frequency current or electrical energy for cutting, coagulation, and ablation. In this process, the tungsten needle electric scalpel serves as an important surgical tool with a wide range of applications and excellent performance. This article will introduce the working principle, application scenarios, advantages and challenges of tungsten needle electrosurgery, as well as future development directions.
1. Technical principles
The tungsten needle electrosurgery is a high-frequency scalpel that uses high-frequency current through a tungsten needle to generate high temperatures to cut tissue and coagulate blood. It consists of three parts: tungsten needle, high frequency generator and control system. The tungsten needle serves as the scalpel head, generating high temperature and quickly cutting tissue; the high-frequency generator generates high-frequency current to supply to the tungsten needle; the control system is used to adjust the current intensity and working time.
2. Application scenarios
Minimally invasive surgery: In minimally invasive surgery, the tungsten needle electric scalpel can cut and coagulate accurately, reducing surgery time and postoperative recovery time.
Neurosurgery: In neurosurgery, tungsten needle electric scalpels can accurately cut brain tissue, reduce damage and bleeding, and improve surgical accuracy.
Cardiovascular surgery: In cardiovascular surgery, the tungsten needle electric scalpel can quickly cut blood vessels and stop bleeding, improving surgical efficiency.
Other fields: Tungsten needle electric scalpels are also widely used in gynecology, thoracic surgery, urology and other fields for cutting and coagulation in various surgeries.
3. Advantages and Challenges
Advantage:
Precise cutting: The tungsten needle electric scalpel can cut tissues and organs accurately, reducing damage and bleeding.
Good blood coagulation effect: The heat generated by high-frequency current can not only cut tissue, but also effectively coagulate blood, reducing postoperative bleeding and complications.
Short operation time: Because the tungsten needle electric scalpel has good cutting and coagulation effects, it can shorten the operation time and reduce the doctor's workload.
Fast post-operative recovery: Due to precise cutting and effective coagulation, post-operative recovery time and pain can be reduced, improving the patient’s quality of life.
challenge:
High equipment cost: As a high-end medical equipment, the tungsten needle electric scalpel has a relatively high price, which limits its application in primary medical institutions.
High technical requirements: Using a tungsten needle electric scalpel requires certain medical knowledge and skills, so the technical requirements for doctors are high.
Possible complications: Although the tungsten needle electric scalpel has better cutting and coagulation effects, there is still a certain risk of complications, such as infection, bleeding, etc.
4. Future development direction
Increased intelligent functions: With the development of artificial intelligence technology, future tungsten needle electric scalpels may have intelligent recognition and automatic control functions to improve the accuracy and efficiency of surgery.
Miniaturization and portability: In order to better meet the needs of primary medical institutions, tungsten needle electrosurgical scalpels may develop in the direction of miniaturization and portability.
Optimized design and materials: By optimizing design and material selection, the performance and reliability of the tungsten needle electrosurgery are improved to make it more in line with clinical needs.
Reduce costs: Through technological progress and large-scale production, the cost of tungsten needle electrosurgical scalpels will be reduced so that they can be used in more medical institutions.
Expand application fields: Tungsten needle electrosurgery still has great application potential in certain special fields, such as deep tissue cutting and hard tissue cutting. In the future, its application fields can be further expanded and its value in clinical treatment can be improved.
In short, as an important medical surgical tool, the tungsten needle electrosurgery plays an important role in many fields such as minimally invasive surgery, neurosurgery, and cardiovascular surgery. With the continuous advancement of technology and the deepening of its application, tungsten needle electrosurgery is expected to achieve more intelligent, miniaturized and portable developments in the future, bringing more treatment advantages and convenience to the medical field.
