The Misonix BoneScalpel® is a novel and unique surgical device in that it offers a gentler osteotomy as compared to standard bone cutting tools. It efficiently slices crystalline bone while leaving elastic soft tissues largely unaffected during incidental contact. This can be particularly important during spinal surgery where bone segments are frequently removed in close vicinity to the spinal cord, nerve roots and major arteries. Ultrasonic cutting of bone is made possible by amplifying an electrical signal and converting it into a high back-and-forth motion of a blunt blade at the extremely high frequency of 22,500 times per second.
Ideally Suited for Limited Access and Visibility in MIS Procedures
- Superior Control in Retractor and Tube-Based Procedures for Precise Bone Cutting
- Deep Cuts Through Osseous Structures with Minimal Blood Loss
- Offers Large amount of Viable Autograft Bone Compared to Shavers or Burrs
The ultrasonically vibrating blade compresses the bone through repetitive impacts at 22,500 times per second cleaving its way into the bone and creating the cut. Tactile feedback allows the surgeon to sense differences in bone density as he or she is cutting through cortical and cancellous layers. Due to its elasticity, soft tissue is minimally affected during incidental contact with the blade. This is beneficial, for example in spinal decompression surgery when bone is being removed to relieve pressure on a spinal nerve to treat spinal stenosis.
