What is the difference between bipolar and unipolar electrocoagulation?

Bipolar electrocoagulation was introduced as early as 1940, and it differs from monopolar electrocoagulation in that it eliminates the ineffective electrodes that are in contact with the patient's buttocks, and instead connects the two electrodes to a pair of tweezers.

The two blades of this tweezer are insulated between the two blades. When the current is applied only through the tissue between the two tips of the tweezers, the amount of electricity required is greatly reduced, generally only 1 4 to 1 3 of monopolar electrocoagulation, and even the power can be reduced to less than 1 10 of monopolar electrocoagulation when hemostasis is stopped in important parts such as the spinal cord, so the heat diffusion and adjacent damage are correspondingly reduced.

In addition, bipolar electrocoagulation occurs in the presence of fluids such as saline and cerebrospinal fluid.

or in the presence of blood, it can also play the role of electrocoagulation and hemostasis, which is also beyond the reach of monopolar electrocoagulation. Monopolar electrocoagulation can be used with a variety of surgical instruments such as hemostats.

Tweezers, suction device, scalpel.

or steel wire snares and other contacts to stop bleeding or cut and other purposes; However, it requires a large amount of electricity, a large range of thermal diffusion, and great damage to the surrounding tissues, and tissue changes can still be seen at a distance of 1 cm from the resection, so monopolar electrocoagulation is not suitable for application in important parts such as cortical functional areas, near important blood vessels, brainstem, spinal cord, nerve roots, etc.

Bipolar electrocoagulation generally refers to bipolar electrocoagulation tweezers, in which the two electrodes are connected to the two blades of a pair of tweezers, and the two blades of the tweezer camera system are insulated. When using, the current is only arranged between the two top-of-the-line medical sterilization boxes with tweezers.

Monopolar electrocoagulation generally refers to an electrosurgical pen in which a large metal plate is in contact with the patient's buttocks as one of the clicks. It should be used in conjunction with the negative plate of the electric knife.

Single-stage electrocoagulation refers to the contact of a large area of metal plate with the patient's buttocks as one of the clicks, which is called the patient's click or inactive electrode; The other electrode is connected to the hemostatic device for electrocoagulation.

Bipolar electrocoagulation: Two electrocoagulation are attached to two blades of a pair of tweezers, which are insulated between the two blades.

Summary. Difference 1: The appearance of the monopolar ablation electrode is mostly straight, and the cutter head can choose different types according to the needs of the operation, such as ordinary knife type, needle type, minimally invasive knife type, retractable type, scraping and suction type, etc., there are generally two function buttons on the monopolar electrocoagulation pen, yellow is cutting, blue is coagulation; The bipolar ablation electrode does not have an electrocution and electrocoagulation button, and the shape is mostly straight or gun-shaped tweezers, and the tip of the tweezers can be selected as dripping or not.

Difference 2: The working principle is different, the monopolar electrocoagulation knife is to gather high-frequency currents and directly destroy the tissue under the electrode head. When the temperature of the tissue or cell rises to the denaturation of proteins in the cell, the function of cutting or clotting occurs in the blood.

Therefore, monopolar electrocoagulation has a significant advantage in rapid incision of tissues; Bipolar electrocoagulation forceps provide high-frequency electrical energy to the body tissues through the two ends of the bipolar forceps, so that the blood vessels between the two ends of the bipolar forceps are dehydrated and coagulated, so as to achieve the purpose of hemostasis.

Please wait patiently for two minutes, we are sorting it out, and we will answer you immediately, and please do not end the consultation.

Difference 3: Different ways of use: When the unipolar surgical electrode is used, it is necessary to match the negative electrode plate pasted to the patient to make the source local use, so that the current can flow back from the negative electrode plate to the electric knife to form a current loop; Bipolar electrocoagulation tweezers do not need to be matched to the negative plates to be used. Difference 4:

The monopolar electrocoagulation knife requires a large amount of power, a large scale of thermal dispersion, and is not accurate enough to deal with hail, so it is not suitable for use in major parts such as the functional area of the cerebral cortex, near the main blood early warning tube, brainstem, spinal cord, nerve roots, etc.;

We are glad to answer your question that vaporization resectoscope is a monopolar electrocoagulation technique. In monopolar electrocoagulation, only one electrode is used as a surgical instrument, while the other electrode is part of the patient's chaotic body. Vaporization resectoscopes use a high-frequency electric current to cut and vaporize tissue, with only one electrode in contact with the patient and the other electrode grounded in the rest of the patient's body.

This technique can be used for many different procedures, including liver resection, cholecystectomy or mitigation, and nephrectomy.

Hello, according to your question: (Does vaporized resectoscope belong to bipolar electrocoagulation or monopolar) for you to find out: Vaporized resectoscope belongs to unipolar electrocoagulation equipment.

In monopole embedded hail electrocoagulation, the liquid ridge passes only through the electrodes in the surgical cutter, while the tissue is placed on the ground as the material to be cut and cut by the sheared sail. A vaporized resectoscope uses an electrically charged electrode to activate a high-frequency electric current that passes it through a tissue or cell, generating heat. This heat can be used to shear or vaporize the tissue.

By adjusting the frequency and power of the current, the efficiency of the cutter and the degree of cutting can be controlled. Bipolar electrocoagulation uses two electrodes to generate an electric current, one of which is on the tissue being cut, while the other electrode is used to receive the current. In this case, the current generates heat only in the tissue between the electrodes, which can be used to stop bleeding or cut the tissue.

Hello, dear, vaporized resectoscope belongs to monopolar electrocoagulation, vaporized resectoscope is a commonly used surgical instrument, mainly used to eliminate the chain of Lachun melting tissue or cutting tissue. It uses the heat generated by a high-frequency electric current to heat the tissue to a vaporized or solidified state, thus achieving the purpose of cutting or ablation. The vaporization resectoscope is a monopolar electrocoagulator, which has only one electrode, and the shed resists the current when passing through the tissue in only one direction, so that the heat generated is also concentrated in only one direction.

In contrast to a unipolar electrocoagulator, a bipolar electrocoagulator has two electrodes, and the current can flow in both directions, so the heat generated is also dispersed in both directions. This structural design can effectively reduce the damage of the current to the surrounding tissues, so it is safer to use a bipolar electrocoagulator in some surgeries. However, in some procedures that require cutting or ablation of large areas of tissue, monopolar electrocoagulators are more convenient to operate, so vaporized resectoscopes are widely used in stool procedures.
