A recently granted patent (Publication Number: US11918245B2) discloses a novel surgical handpiece designed to perform precise surgical procedures. The handpiece comprises a motor with a torsional transducer assembly along its central axis, allowing for connection to a power source. The motor generates a standing wave along the central axis in response to electrical current and voltage, resulting in torsional motion at the working plane of a detachable surgical attachment. This standing wave pattern includes nodes and anti-nodes, with the position of the anti-nodes aligning with the working plane, ensuring accurate tissue engagement.

The patent also details the configuration of the torsional transducer assembly, which includes multiple torsional transducers designed to operate as a full-wavelength resonator along the central axis. Each torsional transducer is equipped with a surface roughness for acoustic contact with adjacent transducers, enhancing the efficiency of the standing wave generation. Additionally, the surgical attachment features an angled adaptor and an ultrasonic tip positioned strategically to correspond with nodes and anti-nodes of the standing wave, optimizing the transmission of torsional motion for precise surgical procedures. The handpiece further includes a connector block and an amplifier aligned along the central axis, enhancing the overall functionality of the device for surgical applications.
