1. A marker deployment system, comprising:
a handle extending radially from and longitudinally along a main axis from a proximal handle end to a distal handle end;
a driver tube coupled to and extending from the handle at the distal handle end along the main axis from a proximal tube end to a distal tube end and defining a tube bore extending axially therethrough, the distal tube end configured to support a bone marker;
an inner rod extending axially through the driver tube from a proximal rod end to a distal rod end including a plurality of distal rod threads comprising a retention fastener configured to engage and selectively secure the bone marker at the distal tube end;
a knob operably coupled to the inner rod and rotatable about a knob axis of rotation extending along the main axis in a first direction to secure the bone marker and in a second direction opposite the first direction to release the bone marker, wherein at least a portion of the handle extends axially beyond the knob to define the proximal handle end; and
wherein the knob axis of rotation is coaxial with the main axis, the knob is configured to rotate with the inner rod and movable axially along the handle, the handle defines a handle cavity extending axially through the distal handle end to a linear translation portion including a plurality of handle threads defined therein, and the proximal rod end extends past the proximal tube end of the driver tube and at least partially into the linear translation portion of the handle cavity and includes a plurality of proximal rod threads configured to threadingly engage one or more of the plurality of handle threads and cause simultaneous rotation about and axial translation of the inner rod along the main axis as the knob is rotated about the knob axis of rotation.
