INDUCTIVE POWER JOINT ALLOWING UNRESTRICTED ROTATION

摘要

A user-held or otherwise supported electrosurgical device can include an endpiece, a fixed first coil or other electromagnetic energy transmitter or receiver and a rotatable second coil or other electromagnetic energy transmitter or receiver wirelessly energized by the first coil. The rotatable second coil can be affixed to a rotatable member extending distally from the endpiece. This can permit unrestricted rotation without being encumbered by wiring or electrical contacts across a plane of rotation.
