Electrosurgical snare

机译:电外科网罗

摘要

The disclosure relates to three enhancements for a surgical snare: an electrosurgical snare in which the loop of snare wire extends from an energy transfer surface which can act both as a physical reaction surface for mechanical cutting using the snare and as a region for emitting electromagnetic energy; a surgical snare having a snare wire having a first end connected to a movable boss that is slidably mounted on a coaxial cable; and a surgical snare having an end cap with a distally facing reaction surface and a pair of channels for guiding a snare wire, where the distally facing reaction surface is arranged to contact the retractable loop when fully retracted.
