Precision bone drill and method of use |
| abstract |
Disclosed is a drilling device and a method for the drilling of human or animal bone tissue. The method comprises the following steps; (a) providing a drill having an electrically conductive bone cutter and an electrically conducting nosepiece assembly spaced apart from the electrically conductive bone cutter and acting as a counter electrode; (b) placing the electrically conductive bone cutter and nosepiece assembly into contact with the bone tissue to be drilled; (c) measuring the electrical impedance between the bone cutter tip and the nosepiece or the current through the cutter motor; (d) commencing drilling and moving the bone cutter toward the bone surface; (e) starting a step counter when the impedance reduces or the cutter motor current increases; (f) incrementing the step counter with every step of the vertical drive motor until the step count reaches the prespecified value thereby controlling the depth of the hole drilled. |
