Apparatus and method thereof for drilling holes in discrete controlled increments
First Claim
1. An apparatus for forming holes, comprising:
- a drill unit for drilling holes, the drill unit including a first guide portion;
a calibrated portion connected to the drill unit for positioning the drill unit;
an advancing lever for transferring a force to the calibrated portion;
a body portion including a hinge for locating the advancing lever, the body portion including a handle portion and at least one channel running along a longitudinal portion thereof communicating with the first guide portion and for locating the drill portion; and
a stability platform attached to the body portion adjacent to a rotating portion of the drill unit, the stability portion for stabilizing the body portion relative to an object;
wherein pulling on the advancing lever towards the handle portion causes the advancing lever to transfer a force to the calibrated portion, said force causing the drill unit to advance towards the stability platform.

Abstract
An apparatus and method for forming a hole in material for non-medical and medical purposes such as a cranial burr hole for ventriculostomy and brain biopsy procedures. The apparatus includes a main unit upon which a drill unit is located. The drill unit includes a drill bit and an on/off switching means. The main unit includes a handle which is suitable for grasping, and an advancing mechanism including a release/engage mechanism, and an advancing lever and an optional on/off switch. The drill unit is advanced a predetermined distance relative to the main unit each time an advancing lever is pulled. In use, the apparatus is placed in a desired position upon the material to be drilled such a patient'"'"'s skull and is stabilized by a stabilization platform, the apparatus is then turned on, and the advancing lever is pulled to advance the drill unit a predetermined distance relative to a longitudinal axis of the main unit with each pull of the advancing lever. The procedure is ended when the desired depth of penetration has been reached, or the material such as in the case of skull bone, has been completely penetrated.
