Abstract
This disclosure relates to drill guides and depth control apparatus for use with a variety of customized or standardized surgical instruments. In embodiments, the apparatus comprises at least a body portion and a collar portion, one or more of which are configured to be coupled to a cutting instrument, such as a drill bit, in a specified location and manner to prevent unwanted movement. In embodiments, the assembly of the body and collar portions may be incrementally adjusted to alter the desired depth of the cutting instrument. Methods for using the foregoing apparatus are also disclosed herein.
Claims19
An apparatus configurable to contact and be secured to an instrument, the apparatus comprising:
- a cylindrical body comprising at least a first portion and a second portion, the first portion having a smaller radial dimension than the second portion, the cylindrical body further comprising a longitudinal axis through a radius of the cylindrical body, the cylindrical body further comprising a bore passing through the cylindrical body and about the longitudinal axis of the cylindrical body for receiving at least a certain length of the instrument, wherein the bore comprises at least one track for engaging at least a portion of the instrument;
- and
- a collar comprising a bore and selectively engageable with the cylindrical body by placement of the first portion of the cylindrical body in the bore of the collar, the bore comprising at least one first section having a first radial dimension and a second expanded section having a second radial dimension greater than the first radial dimension, the bore further comprising at least one detent that is selectively engageable with the instrument.
An apparatus configurable to contact and be secured to an instrument, the apparatus comprising:
- a body comprising at least a first portion and a second portion, the first portion having a smaller radial dimension than the second portion, the body further comprising a central axis and a bore passing through the central axis of the body for receiving at least a certain length of the instrument;
- a cylindrical, hollow collar selectively engageable with the body by placement of the at least a first portion of the body in a hollow portion of the collar, wherein the hollow portion of the cylindrical, hollow collar comprises at least one first section having a radial dimension greater than second section of the hollow portion of the collar;
- the cylindrical, hollow collar comprising a projection substantially parallel to the cylindrical, hollow collar's longitudinal axis and selectively positionable within a slot formed in a surface of the second portion of the body, the projection capable of moving within the slot upon rotation of the cylindrical, hollow collar relative to the body;
- the first portion of the body further comprising at least one tab configured to be displaced radially when the cylindrical, hollow collar is engaged with the first portion of the body and rotated, the displacement of the tab resulting in further contact with the instrument;
- wherein the at least one first section of the hollow portion of the collar is configured to receive the tab without displacing the tab in a first position of use, wherein the first position of use maintains the apparatus in an unlocked position, and wherein the cylindrical, hollow collar may be rotated to cause displacement of the tab in a second position of use which maintains the apparatus in a locked position of use.
