Abstract
A handheld medical instrument for rotating a tool including a support structure having a portion that may be gripped by a user, and an electric motor having an output rotatable at a first speed. A tool rotating shaft extends from the support structure and is adapted to be coupled to a tool to rotate the tool at a second speed. A variable speed transmission is operatively coupled between the output of the electric motor and the tool rotating shaft to transfer rotation therebetween and is selectively adjustable between at least two different ratios of the first speed relative to the second speed.
