Ultrasonic Bone Cutter

Introduction

The ultrasonic bone cutter is a valuable tool in minimally-invasive spine procedures, requiring less space when incising or removing bone than an osteotome. Spine surgeons can now more precisely, and with greater confidence, control their bone cuts in difficult-to-reach areas while better protecting soft tissue. These devices, powered by piezoelectric actuators, allow for precision bone cutting, at ultrasonic frequencies, with little damage to soft and neurovascular tissues. The project consists of the design and manufacturing of an ultrasonic bone cutting device including the development of novel analytical and multiphysics methodologies for its optimization.

Advantages

• Controlled Cutting
• Improved Efficiencies
• Soft Tissue Sparing
• Reduced Bleeding

POWER

The ultrasonic tool provides the ability to make large challenging osteotomies with ease without compromising safety. The speed to which the device cuts through bone allow users to maintain short operative times while improving the efficiency of the procedure.

BONE PRESERVATION

Ultimate control and precision, combined with a thin kerf, allow for cuts and maximize performance while preserving healthy bone. The ultrasonic cutter can preserve a greater percentage of autograft bone with each cut, when compared to standard techniques.

SAFETY

The ultrasonic tool utilizes a non-rotational linear movement that provides tissue sparing effects giving users the confidence to go where they would otherwise be unable to go. Users can achieve greater resections in the vicinity of vital structures.
