Claim 0:
1. A device for forcibly inserting a surgical implant into a receiving bone, by impaction, comprising:
an impactor for impacting an impact surface coupled to the implant and exerting an impact force on the implant,
at least one deformation sensor associated with the impactor, and
a processing unit connected to the at least one deformation sensor,
wherein:
the at least one deformation sensor is adapted for measuring the deformation of the impactor induced by the impact force, and for providing a measurement signal representing the temporal variation of this deformation during an impact,
the processing unit is 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,
the impactor has a striking face for impacting the impact surface, an opposite face, opposite to the striking face, and side faces extending between the striking face and the opposite face, and
the at least one deformation sensor is bonded to at least one face among the side faces and the opposite face, so that the deformation of the at least one face causes the deformation of the at least one deformation sensor.
