I 11e1: Verschiebliche Tracheaiprothese für passagere oder permanente Implantation I 11e1: Movable tracheal prosthesis for temporary or permanent implantation

btand der· Technik: herKomml iche f rachealprotnesen zum langfristigem Trachealersatz sind iilikonronre mit oder ohne arretierenden Ballon, weicne eine einfache Wandung aufweisen mit der sie am Umgebungsgeweoe der Trachea befestigt werden.Technology: Conventional tracheal prostheses for long-term tracheal replacement are silicone with or without a locking balloon, which have a simple wall with which they are attached to the surrounding tissue of the trachea.

Probiem: Bei aen herkömmlichen iracnealprothesen wird die Prothese direkt mit dem Umgebungsgewebe verbunden. Die starken longitudinalen Verschiebungen zwischen Kehlkopf und unterer Resttrachea beim Atmen, Schlucken und Sprechen sind daher nur bedingt möglich bzw. führen zur baldigen Dehiszenz und Fistelbildung mit den entsprechenden Komplikationen. Problem: With conventional laryngeal prostheses, the prosthesis is connected directly to the surrounding tissue. The strong longitudinal displacements between the larynx and the lower remaining trachea during breathing, swallowing and speaking are therefore only possible to a limited extent and lead to rapid dehiscence and fistula formation with the corresponding complications.

Vorteilhafte Wirkungen: Mit der Erfindung wird im angegebenen Anwendungsfall erreicht, daß Rupturen, Substanzverlusten und Stenosen der Luftröhre prothetisch versorgt werden können und die natürliche Verschieblichkeit der Trachea durch den Verschiebespalt zwischen innerer und äußerer Wandung imitiert wird. Durch den Verschiebespalt können frühzeitige Dehiszenzen und Fistelbildung vermieden werden, und dem Patienten ermöglicht die mobile Fixierung der Tracnealprothese größeren Komfort und Lebensgefühi beim Sprecnen, Schlucken und Atmen. Advantageous effects: In the specified application, the invention achieves that ruptures, loss of substance and stenosis of the trachea can be treated prosthetically and the natural mobility of the trachea is imitated by the sliding gap between the inner and outer walls. The sliding gap can prevent early dehiscences and fistula formation, and the mobile fixation of the tracheal prosthesis allows the patient greater comfort and feeling of life when speaking, swallowing and breathing.

Weiterbildung der Erfindung: Durch unterschieai&igr; ehe Längen und üurenmesser der Tracheaiprothese ist eine der oröße des DereKtes und der individuellen Größe der Trachea angemessene Versorgung möglich. Das gleiche Prinzip der doppelten Wandung wäre auch für den üsophagusersat&zgr; denkbar, sowie zur Vermeidung von Fistelbildung bei aer Stimmprothesenimpiantation. Further development of the invention: By using different lengths and diameters of the tracheal prosthesis, it is possible to provide a supply that is appropriate to the size of the trachea and the individual size of the trachea. The same principle of the double wall could also be conceivable for the esophageal replacement, as well as to avoid fistula formation during voice prosthesis implantation.
