Pneumatic clamping device for the knee joint

摘要

The present invention relates to a pneumatic clamping device for the knee joint. Device characterised in that the clamping body 1 is produced as two half-shells 1% joined together by screws 1_ close to their end for fastening to the jack 5, in that the clevis 2 is guided in the clamping body 1, against a bearing face 7 of the latter, by means of attached rails 8 bearing on lateral rims 9 of the clevis 2 and whose face 8% which is opposite the contact face with the latter is inclined towards the middle of the body 1 and interacts with the end 10 of the connecting pin 11 between clevis 2 and lever 4 which is frustoconical and has a semiangle at the centre equal to the angle of inclination of the corresponding face 8% of the rail 8, and in that the link between the clamping body 1 and the jack 5 is produced by means of a flange 13 integral with the jack 5 and provided with two diametrically opposed holes 14 and two journals 15. <IMAGE>
