Mit einer neu entwickelten langen D\u00fcse konnten realistische chirurgische Bedingungen nachgestellt werden. Da Spritzwasser die Sicht behindert, wird der Prozess erstmals \u00fcber Audiosignale \u00fcberwacht, die mithilfe unseres S4DBioAlgorithmus mit den Erosionsprofilen korreliert werden.&nbsp;&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Das System erreicht eine Vorhersagegenauigkeit von 98,93\u202f% und zeigt, dass der Fluidstrahl in Kombination mit AudioMonitoring ein effektives cyberphysisches System zur Tiefensch\u00e4tzung darstellt. Die Arbeit liefert damit zentrale Bausteine f\u00fcr zuk\u00fcnftige minimalinvasive, kalte und adaptive Verfahren zur Knochenzemententfernung.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Welches Problem l\u00f6sen Sie mit Ihrer Forschung?<\/strong>&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Revisionseingriffe, bei denen alter Knochenzement entfernt werden muss, sind heute oft zeitaufwendig, unpr\u00e4zise und riskant. Herk\u00f6mmliche manuelle Methoden k\u00f6nnen zu Knochenverlust, Frakturen oder Perforationen f\u00fchren. Unsere Forschung zeigt eine schonende, automatisierbare Alternative, die das Risiko f\u00fcr Patientinnen und Patienten deutlich reduzieren kann.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Welche potenziellen Auswirkungen haben Ihre Ergebnisse?<\/strong>&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Die Methode k\u00f6nnte k\u00fcnftig zu schnelleren, sichereren und pr\u00e4ziseren Revisionseingriffen f\u00fchren. Sie er\u00f6ffnet die M\u00f6glichkeit, chirurgische Abl\u00e4ufe zu automatisieren, die heute stark von der Erfahrung einzelner Operateure abh\u00e4ngen. Langfristig kann dies die Belastung f\u00fcr Patientinnen und Patienten reduzieren, Komplikationen vermeiden und die Qualit\u00e4t orthop\u00e4discher Versorgung verbessern.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Was ist neu an dem Ansatz?<\/strong>&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Zum ersten Mal wird ein pulsierender Fluidstrahl mit AudioMonitoring und einem StateSpaceModell (S4DBio) kombiniert, um den Abtrag des Knochenzements in Echtzeit vorherzusagen, ohne Sichtkontakt zu ben\u00f6tigen.\n\nZudem stellen wir eine neue lange D\u00fcse vor, die minimalinvasive Eingriffe technisch erm\u00f6glicht.
