ABSTRACT:
A handle carries a dry cell battery which supplies current to a microprocessor which receives signals from a sensor on the end of a bill carried by a staff which projects from the handle. The signal to the microprocessor is converted to a display on the handle. The display has alarms to indicate when the retractor applies too much force to a spinal cord or when the force has been applied for too long a time.
