Phasor arose from the collective thoughts of so many of us neurosurgery residents wondering: "why are we still using a hand-crank drill in this century?"  This thought was brief, overridden by other more pressing clinical matters and needing more food and sleep.

But other problems needed solving:

Why is the drill stop not always reliable? (because it was only tested to 5 pounds in the past...)

Why can self-stopping perforator drills still plunge? (because someone can still push down and plunge, despite the rotation being stopped by the automatic sensor)

Why are we always pulling 5 more things extra for our cranial access kits, while throwing away half the unnecessary items? (don't know, but changed this)

Finally (for Attending physicians and Chief Residents, particularly): how can I sleep better at night knowing my junior resident has a near-zero risk of plunging? (we can try to help with this reason among many keeping you up at night)

​

Fifteen versions of the Drill and Kit each later (because if you ask from opinions from neurosurgery people about Cranial Access Kits, you get them -- and we acted upon these to get Phasor where it is today...  With a drill stop adjustable to a patient's individual skull thickness, able to withstand 50 pounds without plunging (is anyone applying even more than 20 pounds of downward weight and still doing neurosurgery?), and a track record of over 15,000 cases in 250+ hospitals without plunging when properly used, the goals STILL remain (in that order): Safety, Efficiency, and Convenience.
