Cranial drill with sterile barrier
First Claim
1. A medical device comprising:
- a drill assembly comprising in combination;
a MRI compatible cranial drill; and
a drill bit; and
a sterile barrier having an interior portion, a proximal end, a distal end, a proximal opening at the proximal end and an opening at the distal end, the opening at the distal end further comprising a sealed aperture, the drill being insertable into the proximal opening, the sealed aperture constructed and arranged to seal around the drill bit such that the drill assembly is enclosed in the interior portion of the sterile barrier and only a portion of the drill bit extends beyond the barrier into a sterile field.

Abstract
A medical device is provided comprising a MRI compatible cranial drill having a removable sterilizable drill bit and a sterile barrier. The sterile barrier has an interior portion, a proximal end, a distal end, a proximal opening at the proximal end and an opening at the distal end. The opening at the distal end further comprises an aperture. The drill is insertable into the proximal opening, the aperture being constructed and arranged to seal around the drill bit such that the drill is enclosed in the interior portion of the sterile barrier and only a portion of the sterile drill bit extends exteriorly of the barrier. In one embodiment, the medical device includes a MRI compatible adjustable depth stop which limits and defines depth of penetration of the drill. In one embodiment the present invention provides a method for providing access to a body of a surgical patient, which includes providing a medical device comprising in combination a MRI compatible drill and a sterile drill bit, providing a locking trajectory guide, mounting the trajectory guide on the patient'"'"'s body, selecting a predetermined depth and adjusting the depth stop to the predetermined depth, advancing the medical device to the body and aligning it with the trajectory guide, utilizing the medical device to cause the sterile drill bit to penetrate the body the predetermined depth to which the depth stop is adjusted, and removing the sterile drill bit from the body. In one embodiment, the medical device includes a sterile barrier.
