The Ellman Surgitron, commonly used in dermatology practice, is an electrosurgical instrument with a high-frequency waveform that is modified by filtering and undamping the current so that an almost pure cut is possible, yet with a small amount of coagulation. This device was used in six patients undergoing full-thickness eyelid resection (unilateral in three and bilateral in three) for involutional entropion or ectropion. Nine lid margins were cut with scissors, and nine with the electrosurgical instrument. The latter was found to cause minimal tissue damage and to modify the superficial epithelial cell layer very slightly, without causing it to slough. The tissue was cut cleanly, with less bleeding than occurred with scissors incision.
埃尔曼外科高频电刀常用于皮肤科临床,是一种带有高频波形的电外科器械,通过对电流进行滤波和去阻尼处理来改变波形,从而实现几乎纯粹的切割效果,同时伴有少量凝血作用。该器械用于6例因睑皮肤松弛症导致睑内翻或睑外翻而接受全层眼睑切除术的患者(3例为单侧,3例为双侧)。9个眼睑边缘用剪刀切割,9个用该电外科器械切割。结果发现,后者造成的组织损伤极小,对浅表上皮细胞层的改变也非常轻微,不会导致其脱落。组织切割干净,出血比剪刀切口少。
