Description
INDIVIDUAL ALIGNMENT AND EXPANSION OF THE PROSTHESIS
Elegant designs make it possible to adapt KURZ middle ear prostheses to unique anatomical conditions by bending. Stems are easily angulated and bells can be modified to a more open position in the presence of enlarged capitulums adding to a more consistent predictable sizing.
ADAPTATION TO THE STAPES HEAD
For individual expansion of the bell on partial prostheses, KURZ offers a special BELL Expander. This tool uniformly expands any KURZ BELL implant to fit unique dimension of stapes heads while preserving the integrity of the materials. Consequently, the implanted prosthesis is fitted securely and the anatomically shaped bell can transmit incoming sound directly to the articular surface of the stapes.
THUMBSCREW RESTRICTS EXPANSION
The degree of expansion is adjusted by using a thumbscrew on the head of the BELL Expander. The prosthesis stem is positioned into the special slot, whereby the bell is pointing upward. A tapered pin exerts uniform pressure on the bell and expands it gently
