一、引言 外科手术刀的解剖质量应注意不致损伤周围的组织,并要求出血少。电灼刀或激光灼刀可以做到少出血或不出血的操作,然而这两种刀具对周围组织引起损伤,况且激光刀的造价昂贵。如果采用超声手术刀,既能减少刀口对周围组织的损伤又能降低出血。为了研究这种手术刀的解剖质 First, the introduction of surgical scalpel anatomical quality should be careful not to damage the surrounding tissue, and require less bleeding. Electrocautery knife or laser scalpel can be less bleeding or bleeding operation, however, these two kinds of tools cause damage to the surrounding tissue Moreover, the laser knife is expensive. If the use of ultrasonic scalpel, both to reduce the damage to the surrounding tissue and reduce bleeding. In order to study the anatomy of this scalpel
