Title:
ELECTROSURGICAL INSTRUMENT, GENERATOR AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2021/110847
Kind Code:
A3
Abstract:
Various embodiments provide an electrosurgical instrument for delivering electromagnetic (EM) energy and ultrasonic vibrations for treating biological tissue. The electrosurgical instrument comprises: an instrument shaft arranged to convey EM energy and an electrical signal for driving a magnetostrictive ultrasound transducer; a distal end assembly arranged at a distal end of the instrument shaft to receive the EM energy from the instrument shaft and deliver the EM energy from the distal end assembly for tissue treatment; and a magnetostrictive ultrasound transducer arranged to receive the electrical signal from the instrument shaft and generate ultrasonic vibrations around the distal end assembly for tissue treatment. Other embodiments provide an electrosurgical generator, and an electrosurgical apparatus comprising the instrument and generator.
