Patent ID: 7527630

Claim:
An apparatus for the preparation of a femoral condyle for the insertion of monocondylar knee implants, comprising: a spreading device ( 11 ) for the setting of a desired spacing between a femoral condyle and an oppositely disposed tibia plateau and comprising at least one functional attachment ( 13 ) couplable in a vertically adjustable manner with the spreading device ( 11 ), wherein the spreading device ( 11 ) includes a spreading section ( 27 , 29 ), which can be introduced between the femoral condyle and the tibia plateau and which extends substantially perpendicular to the spreading direction, and a handling section ( 21 , 31 ) for the spreading section ( 27 ) which includes an angle α>90° with the spreading section ( 27 , 29 ), wherein the functional attachment ( 13 ) supports a cutting and/or drilling jig ( 35 , 45 ) and is adjustable at least vertically relative to the spreading device ( 11 ) when the desired spacing is set at the handling section ( 21 , 31 ) by means of the spreading device ( 11 ), wherein the spreading device ( 11 ) includes a lower part ( 17 ) supportable at the tibia plateau, an upper part ( 19 ) adjustably guided at the lower part ( 17 ) and an actuation member ( 21 ) adjustably held at the lower part ( 17 ) which cooperates with the lower part ( 17 ) and the upper part ( 19 ) such that a setting movement of the actuation member ( 21 ) can be translated into a spreading movement of the upper part ( 19 ) away from the lower part ( 17 ), and wherein the actuation member ( 21 ) is provided at its free end with a pressure surface ( 23 ) which extends parallel to a lower side of the upper part ( 19 ) which can be acted on by means of the pressure surface ( 23 ).
