Abstract
A combination drill guide and depth gauge surgical instrument and associated method for use during a surgical procedure to implant an acetabular cup component into a surgically-prepared acetabulum of a patient's hip includes an elongated shaft having a drill guide on an end thereof. The instrument also includes a retractable depth probe that may be used to gauge the depth of the holes drilled by use of the drill guide.
Claims18
A surgical instrument comprising:
- an elongated body formed from a polymeric material, the elongated body having (i) a drill guide secured to an end thereof, the drill guide having a guide bore extending therethrough and a metallic drill bushing positioned in the guide bore, and (ii) an elongated channel extending parallel to a longitudinal axis of the elongated body, the elongated channel including a distal end having an opening;
- a depth probe positioned in the elongated channel;
- and
- a thumb actuator operable to move the depth probe from a first position in which the depth probe is retracted into the elongated channel relative to the opening of the distal end of the elongated channel and a second position in which the depth probe extends from the opening of the distal end of the elongated channel and through the guide bore of the drill guide.
A surgical instrument comprising:
- a body having an elongated handle and a drill guide secured to an end of the elongated handle, wherein the elongated handle defines a longitudinal axis and includes an elongated channel extending parallel to the longitudinal axis and wherein the drill guide includes a guide bore extending therethrough and defining an axis that intersects the longitudinal axis;
- a depth probe positioned in the elongated channel, the depth probe having a hook-shaped distal tip extending out of an open end of the elongated channel, and
- an actuator movable relative to the elongated handle and operable to move the depth probe such that the depth probe's hooked-shaped distal tip is extended and retracted relative to the open end of the elongated channel.
A method of implanting an acetabular cup component into a surgically-prepared acetabulum of a patient's hip, comprising:
- positioning a drill guide of a combination drill guide and depth gauge surgical instrument in a desired position within the surgically-prepared acetabulum of the patient's hip,
- advancing a bone drill through drill guide and drilling a hole into bone tissue of the patient's hip,
- removing the bone drill from the drill guide, and
- advancing a depth probe of the combination drill guide and depth gauge surgical instrument through the drill guide and determining a depth of the drilled hole.
