  • Abstract
  • Look Inside

To evaluate the safety of the LCS or the forceps-type ultrasonically activated instrument, animal experi-ments were conducted. The tip of the active blade where cavitation is generated and the sharp edge of the active blade where mechanical cutting occurrs are dangerous zones of the instrument, destroying the contacted tissue. On the contrary the flat side of the blade, which produces no significant tissue damage when contacted within 20 seconds, turned out to be relatively safe. As to clinical use, the efficacy was evaluated during laparoscopic gastric surgery in 48 cases.
