The Principle and Applicability of Bipolar Electrosurgical Unit

The Principle and Applicability of Bipolar Electrosurgical Unit

High frequency surgical unit is divided into monopolar and bipolar. 

monopolar high-frequency surgical unit forms a circuit between the negative electrode plate and the knife pen. 

The following introduces the working principle and applicable surgery of bipolar electric knife:

The principle of bipolar high-frequency electric knife is to provide high-frequency electrical energy to the body tissue through the two tips of bipolar forceps,

causing the blood vessels between the two ends of the bipolar forceps to dehydrate and coagulate, achieving the purpose of hemostasis.

His scope of action is limited to between the two ends, and the degree of damage and impact on the body's tissues are much smaller than that of single machine methods. 

It is suitable for sealing small blood vessels (diameter less than 4mm) and fallopian tubes.

What surgeries are bipolar high-frequency electric knives used for?

Widely used in neurosurgery, maxillofacial surgery, plastic surgery, spinal or spinal cord surgery in orthopedics, as well as fine tissue and site surgeries such as ear, nose, and throat. It is also suitable for patients who have installed pacemakers.

Precautions for the use of bipolar electrocoagulation

During bipolar electrocoagulation, it is necessary to continuously rinse with physiological saline to lower the temperature and reduce tissue scabbing and adhesion of electrocoagulation forceps.

When using, pay attention to using intermittent electrocoagulation as much as possible, with each electrocoagulation lasting about 0.5 times to avoid tissue damage.

The two tips of the electrocoagulation forceps should be kept at a certain distance and should not come into contact with each other to avoid forming a short circuit of current and losing the electrocoagulation effect.

When electrocoagulation occurs in important organizational structures such as the brainstem, hypothalamus, etc., the output should be minimized as much as possible.
