Analysis of the tissue margins of cone biopsy specimens obtained from 40 patients showed varying degrees of thermal and mechanical artifact at the tissue margins. The least artifact was seen in the tissue margins of specimens obtained with the scalpel ("cold knife"). The amount of thermal damage to biopsies obtained via lasers and the radiofrequency unit varied with the instrument employed. However, the quality of the tissue margins of specimens obtained using a radiofrequency surgical unit equipped with a needle electrode on a "pure cut" setting approached the quality of those obtained with the cold knife in their lack of thermal and mechanical artifact.
对40例患者的锥形活检标本组织边缘进行分析，结果显示组织边缘存在不同程度的热损伤和机械损伤。使用手术刀（“冷刀”）获取的标本组织边缘损伤最小。通过激光和射频设备获取的活检标本热损伤程度因所使用的器械而异。然而，在“纯切割”模式下使用配备针状电极的射频手术设备获取的标本，其组织边缘质量在无热损伤和机械损伤方面接近使用冷刀获取的标本。
