Evaluation of the harmonic scalpel in open surgery for abdominal aortic aneurysm

Zeyu Wu, Zhe Chen, Lin Peng

Frontiers of Medicine 2012, Volume 6, Issue 1,   Pages 85-88 doi: 10.1007/s11684-012-0174-x

Abstract:

The harmonic scalpel is a hemostatic device primarily designed for use in laparoscopic surgery.During the last few years, many surgeons have begun to use the harmonic scalpel in open surgery.The aim of the present study is to determine the value of the harmonic scalpel in open operation forOpen surgery performed with the harmonic scalpel on 105 patients was compared with open operation usingThe hospital stay was shorter for the harmonic scalpel group than for the conventional surgery group
