In the last decade, ultrasonically activated scalpels (the Harmonic Scalpel, HS) have been developed and used for both open and endoscopic surgical procedures. The present study compares the deepness of lung tissue damage caused by HS and unipolar electrocautery (EC) in rats.
Ten rats were used for the study. Morphological damage on lung parenchyma of the rats was measured with the ocular micrometer in light microscopy.
The mean depth of the tissue damage was 0.23+/-0.08 mm in the HS group, and 0.33+/-0.10 mm in the EC group. The difference was statistically significant between the 2 groups (p=0.028).
HS induces significantly less tissue damage than EC in rat lungs.
在过去十年中，超声手术刀（谐波手术刀，HS）已被开发并用于开放手术和内窥镜手术。本研究比较了HS和单极电灼（EC）在大鼠中造成的肺组织损伤深度。
十只大鼠用于该研究。在光学显微镜下用目镜测微计测量大鼠肺实质的形态学损伤。
HS组组织损伤的平均深度为0.23±0.08mm，EC组为0.33±0.10mm。两组之间的差异具有统计学意义（p = 0.028）。
在大鼠肺中，HS引起的组织损伤明显少于EC。
