What Are The Advantages Of High Frequency Electrosurgery Unit?

Time:2023-08-13 16:58:12

Advantages of using high frequency electrosurgery unit:

1. The cutting speed is fast, the hemostatic effect is good, the incision is neat, the operation is simple, safe and convenient.


2. Compared with the traditional mechanical scalpel, the use of high-frequency electrosurgery can greatly shorten the operation time, reduce the patient's blood loss and blood transfusion volume, thereby reducing complications and surgical costs.


3. Compared with other electrosurgical instruments (such as laser knives, microwave knives, ultrasonic knives, water knives, semiconductor thermocoagulation knives, etc.), high-frequency electrosurgical knives are suitable for a wide range of operations, easy to enter the surgical site, easy to operate, and cost-effective. etc. superiority.


However, if the high-frequency electric knife cannot be used correctly, it may cause the following hazards to the human body:

(1) Electric shock.

Because the electric knife shell is charged, people who accidentally touch it will be injured by electric shock.


(2) Burns are divided into polar plate burns and non-polar plate burns. Plate burns: The plates are in poor contact and the contact resistance is too large, resulting in heat and burns at the contact points. Non-polar plate burns are caused by man-made grounding of the external system of the electrosurgical knife, causing high-frequency current to circulate between each node and cause electric shock burns.


(3) Low frequency of spark

Low frequency of spark is the most dangerous factor in high-frequency electrosurgical knife. The problem of low frequency of spark is not often caused by burns, but it is more likely to cause danger to the life of the patient.


High-frequency electrosurgery generally imposes strict restrictions on low-frequency leakage current, and the instrument itself should not output low-frequency current, because it is much more dangerous than high-frequency, especially the low-frequency current caused by poor contact of the external cable of the machine. The low-frequency danger is deadly. Therefore, it must be ensured that the external system connection of the instrument is reliable.


The high-frequency electrosurgical knife belongs to Class 3 CF-type medical equipment. The high-frequency power adopts full suspension tuning and balanced output, and has the ability to protect against the effect of defibrillation discharge. However, many workers often fail to operate in accordance with the operating requirements during the use of the high-frequency electrosurgical knife, or are prone to electric shock or burn accidents for various reasons.
