The present invention can simply make simplifying the structure for shoulder joint breast, when reversing with not in a friction reduction, so that refraction, shrine and the interior rotation of sesame/rotating outside/natural upper limb regenerating unit can be embodied naturally, this is technical technical task. For this purpose, the nominal upper limb regenerating unit of this hair, the upper complete ectoskeleton of the normality including supporting patient, above-mentioned complete ectoskeleton support the standing support of above-mentioned upper end not exist Upper complete support does not connect, refraction/shrine of the shoulder of patient and interior rotation/rotating outside/shoulder joint formula turned outside And above-mentioned complete support does not connect, the connection of shoulder joint group connection in, causes outward direction on shoulder to occur to vomit in I more than one direction of rotation, including compensate rubber band.
