Ultrasonic Surgical Platform Integrates Minimally Invasive Therapeutics

A new ultrasonic surgical platform combines cutting, debridement, and aspiration tools into one unified system.

The Misonix (Armingdale, NY, USA) Nexus system is a next-generation integrated ultrasonic surgical platform that combines all the features of the company’s existing solutions into a single system that will also serve to power future solutions. The system includes BoneScalpel, a precision oscillating tool designed for millimeter-wide cuts in bone while sparing surrounding soft tissue; the SonicOne attachment, which provides a debridement tool for cleaning wounds and removing damaged tissue or bacterial biofilms; and the SonaStar ultrasonic aspirator, which removes targeted tissues, such as tumors.


A new proprietary digital algorithm results in more power, efficiency, and control. Physicians can utilize the increased power to improve tissue resection rates, in concert with its proprietary digital algorithm so as to conduct more efficient bone removal procedures. In addition, the system’s a digital touch screen display and smart system setup ensure ease of use, enabling physicians to fully leverage its capabilities. Nexus also incorporates radiofrequency (RF) capabilities, allowing for use in general surgery procedures using proprietary bone-sculpting tips and deep-access and laparoscopic probes.

“Nexus is a powerful, highly integrated, and easy-to-use system that will benefit both healthcare providers and patients by incorporating the latest advances in ultrasonic technology, allowing for increased efficiency and efficacy, and thus improved outcomes,” said Stavros Vizirgianakis, President and CEO of Misonix. “Nexus is a key component of our strategy to increase our presence in the neuro, spine, ortho, wound, and general surgery markets.”

Piezoelectric bone surgery utilizes ultrasonic vibrations to cut hard tissue, while leaving soft tissues untouched by the process. The ultrasonic frequency is modulated to 29 kHz, a low frequency that enables the cutting of the mineralized structures alone. The power is adjusted from 2.8 to 16 W, with preset power settings for various types of bone density. The tip itself vibrates within a range of 60–200 µm, which allows clean cutting with precise incisions.
