ABSTRACT:
A hip cup extraction apparatus (101) comprising a shaft (402), a handle (404), a semicircular cutting blade (406), a spring loaded latching member (408), and a head (100) for removing a hip cup (405) from a pelvic bone (401). The head (100) includes a semispherical section (102) terminating in a substantially planar surface (104), a hip cup extraction apparatus aperture (106), a retaining sleeve (108), and a three sided void (110). The head (100) may be configured for selective attachment to the hip cup extraction apparatus (101). The hip cup extraction apparatus (101) is inserted into the hip cup extraction apparatus aperture (106), and an optional spring loaded latching member (408) retains the head (100) in place. As the head (100) is being attached to the hip cup extraction apparatus (101), the semicircular cutting blade (406) may pass through the three sided void (110). Once the head (100) is attached to the hip cup extraction apparatus (101), the head (100) is inserted into the hip cup (405). Force may then be applied to the hip cup extraction apparatus (101) in order to drive the semicircular cutting blade (406) into the pelvic bone (401). The hip cup extraction apparatus (101) may then be rotated or pivoted such that the semicircular cutting blade (406) passes completely around the hip cup (405).
