[An experimental study of a new ultrasonic scalpel. Observations on the quality of the ultrasonic effect and the prospects for its clinical use on different parenchyma and tissues].
The ultrasonic scalpel has been used for some time in surgery in tissue with a predominantly cellular component since it can be used selectively on the parenchymatous component while respecting the vasculo-stromal component. On the basis of their earlier experience and using a versatile ultrasonic device currently utilised in plastic surgery, the authors subjected a series of animal organs to ultrasonic action at a frequency of 19800 Hz and with an output of 65 Watt. The aim of the study was to evaluate the widest potential in terms of efficiency and safety for the use of a ultrasonic scalpel on a vast range of animal parenchyma (batches of Sprague-Dawley rats). The authors' comments and histological results highlight the striking efficiency of this form of energy in the dissolution of parenchyma while respecting the organ's vascular and stromal components.
