Application of Bipolar Coagulation in Delicate Surgery

With the rise of micro-neurosurgery and cerebrovascular disease surgery (such as intracranial aneurysm and cerebral arteriovenous malformation surgery, and superficial temporal artery and middle cerebral artery anastomosis, etc.), bipolar coagulation has become the most important part of this type of surgery that its electrosurgical function is indispensable to subtle hemostasis.

Bipolar Coagulation VS Monopolar Coagulation

The difference between bipolar coagulation and monopolar coagulation is that the invalid electrode contacting the patient’s buttocks is eliminated, and the two electrodes are respectively connected to the tips of the tweezers. The part between the two tips is insulated. Current does not flow through patient’s body, no patient return electrode is needed. In application, the current only passes through the tissue between the two tips of the tweezers, so the power required is greatly reduced, generally only 1/4 to 1/3 of monopolar coagulation, and it can even reduce the power when hemostasis in important parts such as the spinal cord. It is less than 1/10 of monopolar coagulation so that heat diffusion and adjacent damage are reduced accordingly. In addition, bipolar coagulation can also work in the presence of liquids such as saline, cerebrospinal fluid, or blood, which is beyond the reach of unipolar coagulation.

Compared with silver clip hemostasis, bipolar coagulation is more convenient, no foreign body is left in the tissue, and there is no interference from postoperative CT re-examination. Bipolar coagulation can stop bleeding more accurately and cause less damage to surrounding tissues. Even if coagulation is performed on the surface of the brainstem to stop bleeding, it will not affect the normal activities of breathing and heart. Based on the above-mentioned advantages, it is obvious that it plays a vital part of the current micro-neurosurgical technique which is widely used for the separation and resection of scalp, muscle, dura mater, cerebrovascular, intracranial tumors and other tissues.

Selection of the Forceps for Bipolar Coagution

In addition to the bipolar coagulation power of the electrosurgical unit to match the different degrees of wetness of the surgical wound of different tissues in the operation, selecting the right forcep is also related to a successful operation. Since bipolar condensing tweezers have different tip widths, different tweezers lengths, and bending shapes, The selection principle should be taken the following factors into consideration:
1) Choose the tweezers that do not block your view;
2) The tip of the tweezers has an insulating protective layer;
3) The metal exposed part is small.

EB05 Electrosurgical Unit

Heal Force electrosurgical generator features bipolar coagulation and bipolar cutting functions, with special dripping forceps, is suitable for neurosurgery.

Monopolar Mode

Bipolar Mode (Bipolar Cut & Biopolar Coag)

The current path is confined between the two tines of the forcep. Current does not flow through patient’s body, no patient return electrode is needed. Suitable for delicate operations such as neurosurgery, gynecology, otolaryngology.

Power and Mode Memory

• Take previous settings automatically
• No need of re-setting after boot.

9-Channel Program Memory

9 setting memory for quick response, convenient for surgical operations in various departments.

REM™ Technology

Return electrode monitoring is related to the impedance value according to the change in the contact area of the plate. Once the contact area of the plate drops to a dangerous level, the host automatically cuts off the output.

Can be upgraded to argon knife

It can be linked with an argon device and upgraded to an argon knife to perform APC surgery, widely used for general surgery, hepatobiliary surgery, open surgery and digestive endoscopy for fast and large-scale hemostasis.

CF Type Defibrillator Control

• Avoid electromagnetic interference from Defibrillator
• IEE60601-1&IEC60601-2-2

Adaptive Tissue Technology

• Keep uniform, consistent cutting
• No influence from electrodes or cutting range

Safety System

The audible and visual alarm will be triggered if accessory connection error, operation error, host failure occur when operating. Automatic energy monitoring can monitor high-frequency leakage to prevent personal burns caused by leakage.

Two-Channel Output of Coagulation

Convenient for hemostasis needs of emergency traumatic surgery and coronary artery bypass grafting (CABG).
