ULTRASONIC DENTAL TOOL

摘要

The present invention relates to ultrasonic dental tools having an integral sheath and at least one light source adapted to utilize the electromagnetic energy already available in the existing ultrasonic dental unit. The handpiece includes a substantially hollow housing having a primary power source that may include a coil. In one aspect, the ultrasonic dental insert includes a sheath. The sheath may be formed such that it may cover at least part of the handpiece housing. In general, the sheath may serve as a barrier such that it may reduce cross-contamination to and from the patient's mouth. During operation, the primary coil of the handpiece may be inductively coupled to an illumination energy coil such that the illumination energy coil may draw energy from the electromagnetic field of the primary coil to power at least one light emitting element.
