Abstract
A medical driver can include a handle coupled to a drive shaft. The drive shaft can couple with an access assembly for drilling into bone, and can be displaced relative to the handle from a rotationally restricted state, in which the drive shaft is rotationally restricted relative to the handle, to a drilling state, in which the drive shaft is freely rotatable in at least one direction relative to the handle. The medical driver can further include a mechanical energy-storage device coupled to the drive shaft that can automatically rotate the drive shaft relative to the handle upon transition of the drive shaft to the drilling state. A biasing element can be coupled to the handle and to the drive shaft to provide a bias to maintain the drive shaft in the rotationally restricted state. When distal movement of the drive shaft is opposed, application of a distally directed force on the handle in an amount sufficient to overcome the bias of the biasing element can transition the drive shaft to the drilling state to automatically permit the energy-storage device to rotate the drive shaft relative to the handle.
