Title (EN) DEVICE FOR INSERTING A SURGICAL IMPLANT
(FR) DISPOSITIF D'INSERTION D'UN IMPLANT CHIRURGICAL
Abstract:
(EN) A device for forcefully inserting a surgical implant in a recipient bone by impaction, comprising an impactor (10) that exerts an impaction force on the implant and is associated with at least one sensor (12). The sensor (12) measures a value from among the exerted impaction force and the deformation of the impactor (10) and provides a measurement signal representing the temporal variation of said value during an impact. The sensor (12) is linked to a processing unit (30) that is configured to compute, on the basis of the temporal variation of said value during the impact, an indicator representing the level of contact between the implant and the recipient bone. The indicator corresponds to the duration separating the instant corresponding to the first maximum amplitude peak of the measurement signal from the instant corresponding to the second maximum amplitude peak of the measurement signal. The implant can be a femoral rod (2).
(FR) Dispositif pour insérer en force un implant chirurgical dans un os récepteur, par impaction, comprenant un impacteur (10) qui exerce une force d'impaction sur l'implant et qui est associé à au moins un capteur (12). Le capteur (12) mesure une grandeur parmi la force d'impaction exercée et la déformation de l'impacteur (10), et fournit un signal de mesure représentant la variation temporelle de ladite grandeur lors d'un impact. Le capteur (12) est relié à une unité de traitement (30) configurée pour calculer, à partir de la variation temporelle de ladite grandeur lors de l'impact, un indicateur représentatif du niveau de contact entre l'implant et l'os récepteur. L'indicateur correspond à la durée séparant l'instant correspondant au premier pic d'amplitude maximale du signal de mesure, de l'instant correspondant au deuxième pic d'amplitude maximale du signal de mesure. L'implant peut être une tige fémorale (2).
