Systems and associated methods for ultrasonically-assisted placement of orthopedic implants are described herein. An example system includes an ultrasonic generator, a transducer, and a probe, surgical instrument, and/or an implant. Ultrasonic energy can be delivered to a region of a bone using the system to remove a portion of the bone.

A cutting device of cutting a soft honeycomb mold body in a cutting direction perpendicular to an axial direction of the honeycomb mold body. A cutting device has a wire, a tension supply part and a pair of ultrasonic generators. The wire has a contact part which is stretched and in contact with the honeycomb mold body when the honeycomb mold body is cut. The tension supply part supplies tensile to the contact part when the honeycomb mold body is cut. The pair of ultrasonic generators have respective vibrator terminals arranged in contact with the contact part of the wire. The ultrasonic generators generate ultrasonic vibration in the cutting direction and supply the generated ultrasonic vibration directly to the wire.

A modular sonic vibration buffer system includes an adapter assembly that can be attached to a sonic vibration device. The adapter assembly includes a body with apertures and a plate with arms that are received in the apertures of the body to couple the plate to the body. A cleaning tool is secured between the body and the plate to couple the cleaning tool to the adapter assembly. The sonic vibration device is operable to vibrate the cleaning tool via the adapter assembly. The system also includes additional adapter assemblies and cleaning tools with different characteristics that are attachable to the sonic vibration device in a modular nature for different cleaning or buffering applications.

An ultrasound transducer includes: a piezoelectric element unit including a plurality of piezoelectric elements configured to generate an ultrasound vibration; and a horn that extends from a distal end toward a proximal end to define a longitudinal axis direction and that is connected to a distal end side of the piezoelectric element unit. The horn includes a first transformation portion whose cross-sectional area orthogonal to the longitudinal axis direction decreases toward a distal end, the first transformation portion being configured to amplify amplitude of the ultrasound vibration, and a second transformation portion that is provided between the first transformation portion and a connection position at which the horn and the piezoelectric element unit are connected, the second transformation portion being configured to amplify or attenuates the amplitude of the ultrasound vibration.
