Abstract
An adjustable drill depth guide includes a first sleeve, a second sleeve and a stop member. The first sleeve includes a longitudinal axis and defines a helical slot disposed about the longitudinal axis. The second sleeve is concentrically arranged relative to the first sleeve and is axially adjustable relative to the first sleeve for adjusting a length of the adjustable drill depth guide. The stop member extends radially from the second sleeve and is disposed in the helical slot. The stop member is selectively received at various positions along the helical slot to positively locate the second sleeve relative to the first sleeve in the axial direction.
Claims21
An adjustable drill depth guide comprising:
- a first sleeve having a longitudinal axis and defining a helical slot disposed about the longitudinal axis;
- a second sleeve concentrically arranged relative to the first sleeve and axially adjustable relative to the first sleeve for adjusting a length of the adjustable drill depth guide;
- and
- a stop member radially extending from the second sleeve and disposed in the helical slot, the stop member selectively received at various positions along the helical slot to positively locate the second sleeve relative to the first sleeve in the axial direction.
An adjustable drill depth guide comprising:
- a first sleeve having a longitudinal axis, a first proximal end, a first distal end, a first longitudinal bore extending from the first proximal end to the first distal end, a helical slot disposed about the longitudinal axis, and a plurality of notches extending axially from the helical slot;
- a second sleeve at least partially disposed within the first longitudinal bore, the second sleeve extending along the longitudinal axis from a second proximal end to a second distal end and including a second longitudinal bore and a radially extending stop member selectively engageable with at least one notch of the plurality of notches;
- a third sleeve having a third proximal end, a third distal end, and a third longitudinal bore extending from the third proximal end to the third distal end, the third sleeve concentrically disposed relative to the first sleeve;
- and
- a biasing member disposed substantially adjacent to an outer wall of the third sleeve and biasing the second proximal end in the direction of the third distal end.
A method of adjusting the length of a drill depth guide, the method comprising:
- providing an adjustable drill depth guide including a first sleeve having a helical slot, a second sleeve at least partially disposed within the first sleeve, a radially extending stop member coupled to the third sleeve and operably disposed within the helical slot, and a biasing member biasing a distal end of the second sleeve in a first axial direction;
- moving the radially extending stop member in a second axial direction opposite the first axial direction;
- and
- rotating the second sleeve relative to the first sleeve to move the radially extending stop member in at least one of the first axial direction and the second axial direction.
