Abstract
Disclosed is a medical driving device having a first motor coupled to a region of a first drive shaft; a second motor coupled to a second drive shaft; a coupler coupled to the second drive shaft and interchangeably connected to a working tool; a tool guide assembly comprising a tool guide surrounding the working tool and a surface guide having a distal region configured to couple to the tool guide and a proximal region configured to couple to the first motor, wherein the first motor causes axial motion of the tool guide assembly to a retracted state and drives a length of the working tool into a target region of a bone; a torque sensor configured to sense torque in at least the second motor by continuously measuring current used to drive the second motor; and programmable electronics package to keep RPMs constant. Related methods, systems, and/or articles are described.
