subject: Ultrasonic Dental Handpiece Having A Rotatable Head [print this page] Ultrasonic dental handpiece having a rotatable head
Ultrasonic dental handpieces for holding a transducer is provided. The transducer converts electrical energy into ultrasonic vibrations. The dental handpiece includes a body, a rotator head, and a retainer ring. The body rotatably receives the transducer. The rotator head engages the transducer for rotation thereof. The retainer ring is fixedly coupled to one of the body and the rotator head and rotatably coupled to the other of the body and the rotator head, such that the rotator head is rotatably coupled to the body.
Dental practitioners use ultrasonic dental equipment(instruments) for dental treatments and procedures, such as scaling, periodontal treatments, root canal therapy, and the like. The ultrasonic dental autoclave typically include a handpiece coupled atone end (i.e., a proximal end) to an electrical energy and fluid source via a cable. The cable includes a hose to provide fluid (e.g., water) and conductors to provide electrical energy.
Therefore, there is a need for ultrasonic dental tools that are more comfortable and less fatiguing to use than conventional dental high speed handpiece. Any such new improvements should be downwardly compatible with the numerous electrical energy and fluidsources, handpieces and inserts that are already present in dental offices.
In another exemplary embodiment of the present curing light, an ultrasonic dental unit including an insert and a handpiece is provided. The insert includes a tip and a transducer for converting electrical energy into ultrasonic vibrations. The dental handpieces include a body, a rotator head, a retainer ring and a coil assembly. The body rotatably receives the insert. The rotator head engages the insert for rotation thereof. The retainer ring fixedly coupled to one of the body and the rotator headand rotatably coupled to the other of the body and the rotator head, such that the rotator head is rotatably coupled to the body. The coil assembly excites the transducer.
