“…7,12,19) Technological advances have led to significant improvements in bipolar forceps, enabling effective bleeding control and fine dissection. [1][2][3][4][5]10,11,[13][14][15][16][17][18]20) Nevertheless, the use of this type of forceps remains associated with certain problems such as adherence of charred tissues to the forceps; this problem sometimes leads to hemostasis failure and damage to the surrounding tissues. 2,13,14) In addition, continuous coagulation or coagulation under relatively high electrical output sometimes causes the coagulum to explode or rupture audibly.…”

“…Microwave bumping is an explosion phenomenon that is characterized by the jostling or shaking of the food container and is usually accompanied by an abrupt and explosive sound. 5) This phenomenon is also usually accompanied by the splattering of liquid and food particles on the inside surface of the microwave oven. Although coagulum bumping during bipolar coagulation is common in clinical practice, no previously published studies have described its characteristics.…”

During continuous bipolar coagulation, the coagulum sometimes ruptures suddenly and audibly, leading to hemostasis failure and damage to the surrounding tissues. Such coagulum rupture is a phenomenon that is similar to microwave bumping, which occurs because of unequal heat distribution as a result of sudden elevation in temperature. The present study investigated the conditions under which bumping can occur during bipolar coagulation using samples of whole blood. Two types of bipolar forceps were assessed: forceps with gold-plated tips and IsoCool TM forceps. The time until the bumping phenomenon occurred was measured, and the occurrence rate of bumping was calculated. Thermal characteristics were then assayed using a thermographic camera. As the output of the bipolar coagulator increased, the time until bumping decreased whereas the occurrence rate of bumping during coagulation increased. At lower outputs, the occurrence rate of bumping was significantly lower using IsoCool TM forceps than that using forceps with gold-plated tips (p º 0.0001). Furthermore, bumping during coagulation could be prevented if the tips of the forceps at the coagulation site were repeatedly opened and closed. The bumping phenomenon is influenced by various factors such as heat, electrical power, equipment, and coagulation technique. Neurosurgeons should understand the technical certain aspects of these surgical tools and develop appropriate advanced techniques for temperature control.

“…Correct selection of the bipolar generator type (i.e., closed-loop feedback models), generator setting, coagulation time, specific type of bipolar and tip geometry (diameter and tip angle), tip type (ISOCOOL, SilverGlide [Stryker Neurovascular, Fremont, California, USA]), tip surface and coating, trajectory and angle of the forceps, and time of activation and irrigation, along with such secondary elements as approach, surgical technique (exposure, dissection), and visualization, can contribute to the effective and safe use of bipolar cautery, with a reduction in collateral thermal damage (1,5,16).…”

“…Like argon beam coagulation, saline irrigation may effectively expose raw tissue surfaces by washing away residual blood and when combined with electrocautery has been shown to provide excellent microvessel hemostasis [3,7]. The TissueLink Floating Ball (TissueLink Medical, Dover, NH, USA) is a new commercially available device that provides noncontact, monopolar cautery and uses a continuous flow of saline to improve the electrode-to-tissue interface.…”
