1. A device for inserting a bone screw into a bone, comprising:
a driving member including a housing, a shaft extending distally from the housing to a distal end configured to engage a driving recess of a bone screw, and a coupling element extending proximally from the housing to be coupled to a power driver, a channel extending longitudinally through the driving member;
a control knob configured to be housed within the housing so that a channel of the control knob is in coaxial alignment with the channel of the driving member; and
a retaining member including a rod extending longitudinally from a proximal end to a distal end configured to be inserted into and to mechanically engage a retaining feature of the driving recess of the bone screw, the rod sized and shaped to be longitudinally inserted through the channels of the driving member and the control knob, a proximal portion of the rod configured to engage the channel of the control knob in an assembled configuration.
