Spine surgery with bone instrument

Targeted bone resection

Surgical procedures on the spine are routine operations and yet due to the proximity of important sensitive neurovascular structures, they are always very challenging. They therefore require intelligent solutions, such as the ultrasonic technology from Söring. This method offers the significant advantage that different effects are displayed distinctly and to varying degrees on various types of tissue. Bone is primarily affected by mechanical removal, whereas mostly no mechanical effect is visible on tissue containing collagen with high elastin content (e. g. blood vessels, nerve fibres, dura mater). Due to lower temperature at the tissue tip interface compared to other technologies there is also low risk of heat related damage. This allows precise preparation of the bone in the immediate vicinity of extremely delicate structures on the spine.

Principle of ultrasonic technology in spinal surgery

The ultrasonic oscillations of the sonotrode tip combined with the manual movement of the bone instrument allow a precise and controlled cutting through bone and a targeted bone removal. Elastic structures are significantly more resistant to ultrasonic oscillations. Since they can adapt to the oscillations, they remain intact in the event of contact with the sonotrode tip.
