(DE) VORRICHTUNG UND VERFAHREN ZUR BESTIMMUNG DES VERANKERUNGSZUSTANDES EINER IMPLANTIERTEN ENDOPROTHESE
(EN) DEVICE AND METHOD FOR DETERMINING THE STATE OF ANCHORING OF AN IMPLANTED ENDOPROSTHESIS
(FR) DISPOSITIF ET PROCÉDÉ DE DÉTERMINATION DE L'ÉTAT D'ANCRAGE D'UNE ENDOPROTHÈSE IMPLANTÉE
Abstract
(DE)
Bei einer Vorrichtung (10, 10') zur Bestimmung des Verankerungszustandes einer implantierten Endoprothese (12, 12') umfassend: - Mittel zur Schwingungsanregung der Endoprothese (12, 12'), und - Mittel zum Erfassen des Schwingungszυstandes der Endoprothese (12, 12'), wird vorgeschlagen, dass die Mittel zur Schwingungsanregung der Endoprothese (12, 12') dazu angelegt sind, ein moduliertes Uitraschallsignal auszusenden, umfassend ein Ultraschallträgersignal und ein durchstimmbares Modulationssignal.
(EN)
In a device (10, 10') for determining the state of anchoring of an implanted endoprosthesis (12, 12'), comprising means for oscillation of the endoprosthesis (12, 12') and means for detecting the state of oscillation of the endoprosthesis (12, 12'), it is proposed that the means for oscillation of the endoprosthesis (12, 12') are designed to emit a modulated ultrasound signal, comprising an ultrasound carrier signal and a tunable modulation signal.
(FR)
Dispositif (10, 10') servant à déterminer l'état d'ancrage d'une endoprothèse implantée (12, 12') et comprenant : - des moyens pour appliquer des oscillations à l'endoprothèse (12, 12'), et - des moyens pour détecter l'état d'oscillation de l'endoprothèse (12, 12'), les moyens d'application d'oscillations à l'endoprothèse (12, 12') étant agencés de façon à émettre un signal ultrasonore modulé comprenant un signal de fréquence porteuse ultrasonore et un signal de modulation à fréquence variable.
