Abstract

La présente invention concerne un dispositif de mécanisme de transport de transducteur ultrasonique intégré dans une cartouche (200) pour un dispositif de soins de la peau à ultrasons focalisés de haute intensité (HIFU). La cartouche (200) pour un dispositif de soins de la peau HIFU comprend une première chambre (291) et une seconde chambre (292). De plus, le dispositif de mécanisme de transport de transducteur ultrasonique selon la présente invention est installé dans la première chambre (291), et un transducteur ultrasonique (201) qui est relié au dispositif de mécanisme de transport est disposé dans la seconde chambre (292). Le dispositif de mécanisme de transport de transducteur ultrasonique comprend : un module de transport (211) qui est couplé au transducteur ultrasonique (201) ; un moteur piézoélectrique (216) ; un transporteur (202) disposé au-dessus du module de transport (211) ; et un arbre de carbone (215) dont une extrémité est reliée au moteur piézoélectrique (216) et l'autre extrémité est fixée à une tige de fixation (218) à l'intérieur de la première chambre, et au niveau de laquelle le transporteur (202) est prévu. Par entraînement du moteur piézoélectrique (216), le transporteur (202) effectue un déplacement défini le long de l'arbre de carbone, de telle sorte que le transducteur ultrasonique (201) qui est relié au module de transport (211) soit déplacé.
