1. An instrument guiding device comprising:
a base platform partially formed along a first axis and comprising an inner opening, wherein the inner opening is partially enclosed by the base platform and adapted to receive a medical tool; a plurality of legs, the legs configured to engage an outer surface of a skull; a first guide plate attached to the base platform and configured to provide guidance to an instrument guide component along a second axis; and a second guide plate removeably and pivotally attached to the base platform and configured to provide guidance to the instrument guide component along a third axis; the instrument guide component having an inner channel fluidly connecting a first end of the instrument guide component to a second end of the instrument guide component, wherein the first end of the guide component is pivotally attached to a bottom end of the second plate enabling the guide component to be selectively pivoted between a first side edge of the second plate and a second side edge of the second plate; and a first arcuate insert disposed on a surface of the first plate; a magnetic attachment element disposed on the first side edge of the second plate, the magnetic attachment element configured to removeably and magnetically attach to the first insert of the first plate at a user-selected position along the first insert; a second arcuate insert disposed on an instrument guide component facing surface of the second plate; wherein the first end of the guide component is pivotally and magnetically attached to the second plate using a second magnetic attachment element; and a third magnetic attachment element disposed proximate to the second end of the guide component and configured to magnetically engage the second insert at a user-selected position along the second insert.
