Adjustable drill depth guide

A method of adjusting a length of a drill depth guide, the method comprising:

• providing an adjustable drill depth guide comprising:
• a first sleeve having a helical slot;
• a second sleeve at least partially disposed within the first sleeve, the second sleeve having a proximal end;
• a radially extending stop member coupled to the second sleeve and operably disposed within the helical slot;
• a surface-contacting sleeve rotatably coupled to the first sleeve and axially locked with the first sleeve, the surface-contacting sleeve having a distal end;
• and
• a biasing member biasing the second sleeve in a first axial direction of the surface-contacting sleeve;
• 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 a least one of the first axial direction and the second axial direction to change a distance between the proximal end and the distal end.

A method of adjusting an adjustable drill depth guide, the method comprising:

• engaging a distal end of a surface-contacting sleeve with a surface, the surface-engaging sleeve defining a drill axis;
• moving a handle connected to a control sleeve to rotate the control sleeve relative to the surface-contacting sleeve and to position the drill axis;
• and
• adjusting an axial position of an adjustment sleeve relative to the control sleeve to define an overall length of the adjustable drill depth guide along the drill axis.

A method of adjusting a length of a drill depth guide, the method comprising:

• engaging a distal end of a surface-contacting sleeve with a surface;
• positioning a control sleeve connected to the surface-contacting sleeve;
• adjusting an axial position of an adjustment sleeve relative to the control sleeve to define an overall length of the adjustable drill depth guide along the drill axis;
• and
• viewing depth indicia on the adjustment sleeve through a window in the control sleeve to provide an indication of a drill depth of a drill bit extendable through the drill depth guide.
