Beschreibung
Zusammenfassung:	The invention relates to a hearing instrument, comprising an audio signal source (28), an audio signal processing unit (34) for processing the audio signals provided by the audio signal source, and an implantable stimulation assembly (18) for stimulating a middle ear or inner ear component of the hearing of a patient, wherein the stimulation assembly comprises: an actuator (20) to be coupled to said hearing component for vibrating said hearing component according to the processed audio signals, a non-variable first support member (62, 162) to be directly fixed at the patient's skull, a second support member (64) at which the actuator is fixed and which is guided by the first support member for axial movement with regard to the first support member, an adjustment member (66) engaging with the first support member and the second support member for manually adjusting the axial position of the second support member with regard to the first support member during implantation, and means (68, 268) for locking the adjustment member so as to lock the axial position of the second support member with regard to the first support member once a desired position has been reached. L'invention concerne un instrument auditif comportant une source de signaux audio (28), une unité de traitement de signaux audio (34) pour traiter les signaux audio produits par la source de signaux audio, et un ensemble de stimulation implantable (18) pour stimuler un élément auditif de l'oreille moyenne ou de l'oreille interne d'un patient. L'ensemble de stimulation comporte un actionneur (20) à accoupler audit élément auditif pour faire vibrer l'élément auditif selon les signaux audio traités, un premier élément de support non variable (62, 162) à fixer directement sur le crâne du patient, un second élément de support (64) sur lequel est fixé l'actionneur et qui est guidé par le premier élément fixe pour un déplacement axial par rapport au premier élément de support, un élément de réglage (66) s'emboîtant dans le premier élément de support et dans le second élément de support pour un réglage manuel de la position axiale du second élément de support par rapport au premier élément de support, pendant l'implantation, et un moyen pour bloquer l'élément de réglage de sorte à bloquer la position axiale du second élément de support par rapport au premier élément de support, une fois la position voulue atteinte.
