  • Patent number: 5803088
    Abstract: A heel cup for a medical examination table has a solid bottom, and a heel receiving area that comfortably cradles the patient's heel. The rear portion to receive the heel is spherically shaped so the patient's heel can rotate as required and maintain the comfort of the patient. The forward portion that receives the extending foot of the patient is cylindrically shaped so the patient's foot will have a comfortable supporting surface regardless of the angle of the foot in the heel cup. A stub shaft extends from the rear of the heel cup for mounting the heel cup on the examination table. The stub shaft is positioned so that, when the heel cup is fixed to the table, the heel cup will be oriented as a mirror image of the patient's acetabulum. Thus, the patient's leg can move freely, rotating in the acetabulum at one end, and the heel cup at the other.
