Mechanical prosthesis for middle ear bones - comprises metal wire bent to define part-rigid, part-flexible shaft linking drum component to bearing surface of stirrup bone

摘要

The prosthesis for middle ear bones consists of a drum-type assembly, with a mechanical connecting shaft bearing against the plate surface of the stirrup bone. The connecting shaft is formed from elastic material. The connecting shaft may be of composite construction, consisting of a rigid portion (3) and a flexible portion (2), both formed of metal wire bent into the required shape. ADVANTAGE - Simplified mechanical construction, with reduced risk of rejection of implant.
