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.

The universal modular component external fixation system as set forth in claim 1, further comprising: said compression pin having a head portion, said head portion being located adjacent said tool portion, said head portion being adapted for abutting an outer surface of the fractured bone when said threaded portion of said compression pin passes completely through a first part of a fractured bone and is securely coupled to a second part of the fractured bone such that said compression pin is adapted for biasing the first and second parts of the bone together until properly healed. 3. The universal modular component external fixation system as set forth in claim 2, further comprising: said compression pin including a guide wire, said guide wire being insertable into said compression pin such that said guide wire protrudes outwardly from said point end of said compression pin, said guide wire being positioned in the bone prior to screwing in said compression pin such that said guide wire is adapted for predetermining a desired angle and location of said compression pin by viewing x-rays with said guide wire inserted thereby assuring proper placement of said compression pin in the fractured bone. 4. The universal modular component external fixation system as set forth in claim 3, further comprising: a plurality of said compression pins comprising a plurality of lengths of said insertion portions for the purpose of matching a particular compression pin to a specific bone fracture requirement. 5. The universal modular component external fixation system as set forth in claim 1, further comprising: said frame assembly including a drill guide assembly, said drill guide assembly comprising a guide holder, a plurality of drill guides, and a trocar, said trocar being insertable
