摘要：
A pedicle breach detection device is disclosed. When a pilot hole is created during spinal fusion surgery to facilitate placement of a pedicle screw, it is important to determine if the created hole or tract has breached the vertebrae. A breach can be dangerous to the patient and cause pain, permanent damage, and the necessity for revision surgery. The present invention uses an accelerometer based shaft and ball tip to capture low level mechanical vibrations from the shaft to provide a definitive breach alert to the surgeon using audible, visual, tactile and haptic alert de vices.
