<p>The invention discloses a device for an artificial leg comprising a tube (10) having a proximal sleeve (20) which together with a connecting sleeve (21) attached to a prosthetic sleeve (23) forms an adjustment head. By means of the adjustment head, in part a setting of the angular position of the tube relative to an imagined load line, and in part a setting of the translatory position of the tube relative to the connecting sleeve (21) will be achieved. The adjustment device for the translatory position of the tube additionally includes a supporting plate (32) facing the connecting sleeve (21), the plate having a downwardly facing convex supporting surface (35) resting on a corresponding concave surface of the proximal sleeve (20). The connecting sleeve (21) demonstrates a central bore (33) permitting a bolt or screw (34) to pass through to be translatory displaced relative to the connecting sleeve (21). Furthermore for the setting of the angular position of the tube there is a pyramid adapter stud (42) integrated with the convex surface (35) of the supporting plate (32) and provided with a through-hole (44) for passing the screw (34). The screw obtains a maintained alignment relative to the connecting sleeve (21) independent of the angular position set and is fixed by means of a number of screws in the proximal sleeve, the number of screws corresponding to the number of inclined sides of the pyramid adapter stud.</p> |
