The importance of sealing small vessels by electrocoagulation in microsurgery is well known. In practice, the reliability of both short and long time results obtained with common and bipolar forceps with radiofrequency application is variable, particularly when encrusted coagulations adhere to the forceps tips and there is danger of damaging the vessel when the forceps are withdrawn. The coagulation process involves a sudden change in tissue characteristics, that occurs within a narrow temperature range, closely following the pattern of the applied current and is only modified by heat dissipation to the cooler parts, such as the forceps tips. Keeping these principles in mind, we developed an improved device which provides: A well-balanced current flow between the tips, which is unaffected by wiring, distributed capacitance and current leakage of the electrocoagulator ; a time-dependent heating pattern that coagulates only the core of the clamped tissue.
在显微外科手术中，通过电凝封闭小血管的重要性是众所周知的。实际上，使用普通和双极镊子施加射频获得的短期和长期结果的可靠性是可变的，特别是当结痂的凝血附着在镊子尖端上，并且在拔出镊子时有损坏血管的危险时。凝血过程涉及组织特性的突然变化，这种变化发生在狭窄的温度范围内，紧密跟随施加电流的模式，并且仅通过向较冷部分（如镊子尖端）的散热来改变。牢记这些原理，我们开发了一种改进的设备，该设备具有：尖端之间平衡良好的电流流动，不受布线、分布电容和电凝器漏电的影响；一种随时间变化的加热模式，仅使被夹住组织的核心凝结。
