MICROWAVE COAGULATING SCALPEL

摘要

MICROWAVE COAGULATING SCALPELABSTRACT OF THE INVENTIONA means and method for using a microwave coagulatingscalpel which simultaneously severs and coagulates highlyvascular tissue is disclosed. The scalpel blade forms botha cutting edge and a microwave radiator loop, with the diameterof the loop related to the wave length of the microwave frequency,when the microwave energy is propogated in highly vasculartissue. A range of 100 MHz to 13,000 MHz is disclosed withpreferential frequencies at 2450 MHz and 5800 MHz. A meansto de-energize the microwave source when the blade is removedfrom the highly vascular tissues also disclosed.
