Abstract
A surgical instrument for implanting an acetabular prosthetic component is disclosed, wherein the surgical instrument includes a modular head. A plurality of locking pins extends from the modular head. A locking arm extends from the modular head and is movable between an open position and a closed position. A surgical handle extends from the modular head. The modular head is removably coupled to the surgical handle. The surgical handle engages a first locking pin to lock the modular head to the surgical handle. A linkage assembly engages a second locking pin to actuate the locking arm.

A surgical instrument for implanting an acetabular prosthetic component comprising:
- a modular head comprising:
- a proximal end to retain the acetabular prosthetic component and an opposite distal end,
- a plurality of locking pins extending from the distal end of the modular head,
- a cap positioned at the proximal end of the modular head, the cap including a cap surface, and
- a locking arm extending from the proximal end of the modular head, the locking arm movable between an open position and a closed position, the locking arm positioned adjacent the cap, wherein in the open position the locking arm is spaced further from the cap than in the closed position;
- and
- a surgical handle extending distally from the modular head, the modular head being removably coupled to a proximal end of the surgical handle, the surgical handle comprising:
- a user-operated button having a body that engages a first of the plurality of locking pins of the modular head to lock the modular head to the surgical handle, and
- a linkage assembly engaging a second of the plurality of locking pins to actuate the locking arm.
A surgical instrument for implanting an acetabular prosthetic component having a modular head comprising:
- a proximal end to retain the acetabular prosthetic component and an opposite distal end,
- a hemi-spherical outer surface positioned at the proximal end and sized to receive a hemi-spherical concave surface of the acetabular prosthetic component,
- a circular rim extending circumferentially around the distal end of the hemi-spherical outer surface,
- a stationary pin and a moveable pin extending from the distal end of the modular head, and
- a locking arm extending from the proximal end of the modular head, the locking arm hingedly coupled to the moveable pin, the moveable pin being moveable linearly in a first direction and a second direction to pivot the locking arm between an open position and a closed position, wherein in the open position the locking arm is spaced further from the hemi-spherical outer surface than in the closed position.
