Abstract
A pulsed erbium garnet laser (30 Hz at 2.78 micrometers ) was used to characterize cutting on various soft tissues. Bovine heart, porcine liver and chicken breast were cut, and the resultant craters cut were microscopically examined. The variation of crater depth with average power settings and number of pulses was studied in detail. The second part of the study was to evaluate the coagulation effect of the erbium laser on surgical cuts induced into mucosal soft tissues. Conclusions of this study will be provided from qualitative analysis of the histopathological data.
