Abstract
A device for gauging the size of a bone socket comprising a hemispherical member having a pole on its axis at the distal end and having a bore on its axis at its proximal end; a handle releasably attached to the bore of the hemispherical member; and a pressure responsive surface on the hemispherical member to constitute a pressure responsive surface for changing characteristics when brought in contact with a bone socket to be gauged. The change in characteristics may be in color or shape. Also disclosed is the method for using the device.
Claims11
A device for gauging the size of a bone socket comprising:
- a hemispherical member having a pole on its axis at the distal end and having a bore on its axis at its proximal end;
- a handle releasably attached to the bore of the hemispherical member;
- and
- a pressure responsive surface means on the hemispherical member for changing characteristics when brought in contact with a bone socket to be gauged.
A method for gauging the size of a bone socket to be provided with a hemispherical prosthetic device comprising:
- providing a hemispherical member with a pressure responsive contact surface changeable in readable characteristic upon the application of pressure;
- inserting the contact surface into pressure contact with the bone socket to be sized in order to change the contact surface;
- terminating the inserting and pressure contact of the contact surface when a predetermined pressure has been reached;
- withdrawing the contact surface;
- reading the contact surface which has been changed in characteristic.
