Method for making a mold of an amputation stump, and molding aid for such a method

Abstract

A method for making a mould of an amputation stump, in which the amputation stump is inserted into a liner of a moulding aid, the liner having a longitudinal direction and a circumference, and the liner having an expansion coupling such that when the liner is extended in the longitudinal direction, this necessarily results in a reduction of the circumference.

1 . A method for making a mold of an amputation stump, the method comprising:
 inserting the amputation stump into a liner of a molding aid, the liner having a longitudinal direction, a circumference, and an expansion coupling;   lengthening the liner along the longitudinal direction to reduce the circumference, wherein the amputation stump is measured optically after insertion into the liner.   
     
     
         2 . The method as claimed in  claim 1 , wherein the amputation stump, after insertion into the liner, is loaded by the patient. 
     
     
         3 . The method as claimed in  claim 1 , wherein the amputation stump, prior to insertion into the liner, is equipped with a molding material and a release layer. 
     
     
         4 . (canceled) 
     
     
         5 . The method as claimed in  claim 3 , wherein after insertion of the amputation stump into the liner, the amputation stump and the molding material is shaped. 
     
     
         6 . A molding aid for use with a method for making a mold of an amputation stump, the molding aid comprising:
 a liner for receiving an amputation stump, the liner having a longitudinal direction, a circumference, and an expansion coupling, the liner configured to reduce its circumference upon lengthening of the liner in the longitudinal direction; and   a laser measuring device for optically measuring the amputation stump after insertion of the amputation stump into the liner.   
     
     
         7 . The molding aid as claimed in  claim 6 , wherein the liner has or is made of a braided tube or a net of intersecting fibers, wherein the fibers, in an unloaded state, enclose an angle of 45° with the longitudinal direction of the liner. 
     
     
         8 . The molding aid as claimed in  claim 6 , wherein the liner is held in a retaining device. 
     
     
         9 . The molding aid as claimed in  claim 8 , wherein the retaining device is adjustable in height. 
     
     
         10 . The molding aid as claimed in  claim 9 , wherein the liner is deflected around a ring and guided back onto itself, and wherein the ring with the liner comes to bear on the retaining device. 
     
     
         11 . The molding aid as claimed in  claim 8 , wherein the retaining device is exchangeable or expandable. 
     
     
         12 . The molding aid as claimed in  claim 8 , wherein the retaining device is secured on a support device. 
     
     
         13 . The molding aid as claimed in  claim 12 , wherein the retaining device is arranged foldably on the support device, and in one position engages in latching elements or is clamped or wedged onto the support device. 
     
     
         14 . A method for making a mold of an amputation stump, the method comprising:
 inserting the amputation stump into a liner of a molding aid, the liner having a longitudinal direction, a circumference, and an expansion coupling;   lengthening the liner in the longitudinal direction to reduce the circumference, the lengthened liner providing the mold of the amputation stump; and   optically measuring the amputation stump after insertion into the liner.   
     
     
         15 . The method as claimed in  claim 14 , further comprising loading the amputation stump by the patient after insertion of the amputation stump into the liner. 
     
     
         16 . The method as claimed in  claim 14 , further comprising, prior to insertion of the amputation stump into the liner, equipping the amputation stump with a molding material and a release layer. 
     
     
         17 . The method as claimed in  claim 16 , further comprising shaping at least one of the amputation stump and the molding material, after insertion of the amputation stump into the liner.
