The Cranial Drilling Device puts a hole in skulls, not brains

If you told us on Monday that we’d be capping our week off by checking out an innovative cranial drill, we likely would have just stared at you funny. But here were are and here it is, a device referred to, quite straightforwardly, as the Cranial Drilling Device with Retracting Drill Bit After Skull Penetration. The drill was designed by a team of researchers at Harvard in order to address a major shortcoming with manual drills. Such devices require neurosurgical training in order to know precisely when to stop so as to not damage underlying brain tissue. In certain instances, such as emergency rooms and the backs of ambulances, medical practitioners may require a cranial drill in order to perform procedures such as the insertion of pressure monitors, with nary a neurosurgeon to be found. The Harvard team has concocted a drill that automatically retracts back into its protective casing, as soon as it’s finished drilling through the skull, using a bi-stable mechanism that is active as the drill spins.

The folks at Engadget got a lab tour at Harvard where they saw some interesting technologies that scientists and engineers are working on, including this mechanism called the Cranial Drilling Device with Retracting Drill Bit After Skull Penetration. As the name implies, the bit recedes back into the housing once pressure on its tip drops, preventing it from entering the soft tissue of the brain.

Currently, drilling is typically done with a hand-cranked device that surgeons are trained to safely operate. The new tool should help increase safety while speeding up the drilling process, and perhaps may lend itself to use by non-neurosurgeon clinicians for performing trepanations for intracranial pressure monitoring and other uses.
