A device for forcibly inserting a surgical implant into a receiving bone (), by impaction, comprising an impactor () which exerts an impact force on the implant and is associated with at least one sensor (). The sensor () measures the deformation of the impactor (), and provides a measurement signal representing the temporal variation of the deformation during an impact. The sensor () is connected to a processing unit () configured to calculate, on the basis of the temporal variation of the deformation of the impactor () during the impact, an indicator representative of the level of contact between the implant and the receiving bone ().

Device for inserting a surgical implant

A device for forcefully inserting a surgical implant in a recipient bone by impaction, comprising an impactor () that exerts an impaction force on the implant and is associated with at least one sensor (). The sensor () measures a value from among the exerted impaction force and the deformation of the impactor () and provides a measurement signal representing the temporal variation of said value during an impact. The sensor () is connected to a processing unit () 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 ().
