Process for manufacturing an inner conical recess for receiving an amputated extremity |
摘要 |
An inner conical recess fitting (1) which is connectable to the prosthesis and is intended for receiving a stump (17) of an amputated extremity can be fitted directly to the stump (17) without the aid of modeling in the following procedural steps: to mold the inner conical recess, a plastic which is shrinkable through the action of external influences, such as heat, is selected; a tube (14) which is made of this plastic and is open at at least one end and has a smaller diameter and a smaller length than the inner conical recess fitting (1) to be manufactured is extended and stretched, so that it has in every direction a greater dimension than the inner conical recess fitting (1) to be manufactured; and the widened and stretched molded piece (10) is placed on the stump (17) and is made to shrink through, e.g., application of heat at selected locations, until the fitting bears everywhere securely against the stump.
