"Microneedle" electrocautery was compared against the standard-size needle electrocautery and the Shaw hemostatic scalpel to determine the differences in tissue necrosis when used as a cutting instrument. Incisions were made on the dorsal skin of anesthetized white rats using each of the three devices with the no. 15 scalpel as control. The specimens were submitted for histological evaluation. The microneedle caused less necrosis than the standard-size needle electrocautery (0.18 vs 0.27 mm, p < 0.01) and less necrosis than the Shaw hemostatic scalpel set at 220 degrees F (0.18 vs 0.25 mm, p < 0.05). The microneedle electrocautery was also found to be an instrument that causes very little tissue distortion during fine dissection and helps to minimize blood loss in craniofacial and neurosurgical operations.
将“微针”电灼术与标准尺寸针状电灼术和肖氏止血手术刀进行比较，以确定它们作为切割器械使用时组织坏死情况的差异。使用这三种器械分别在麻醉的白色大鼠背部皮肤做切口，以15号手术刀作为对照。将标本送去做组织学评估。微针造成的坏死比标准尺寸针状电灼术少（0.18对0.27毫米，p<0.01），且比设置为220华氏度的肖氏止血手术刀造成的坏死少（0.18对0.25毫米，p<0.05）。还发现微针电灼术是一种在精细解剖过程中引起组织变形非常小的器械，有助于在颅面和神经外科手术中减少失血。
