Abstract: A device for forcibly inserting a surgical implant into a receiving bone (4), by impaction, comprising an impactor (10) which exerts an impact force on the implant and is associated with at least one sensor (12). The sensor (12) measures the deformation of the impactor (10), and provides a measurement signal representing the temporal variation of the deformation during an impact. The sensor (12) is connected to a processing unit (30) configured to calculate, on the basis of the temporal variation of the deformation of the impactor (10) during the impact, an indicator representative of the level of contact between the implant and the receiving bone (4).

Abstract: A device for assessing the solidity of a material comprising an ancillary tool (2) having an end (2B) in the form of a point or blade, an impactor (4) for striking the ancillary tool (2), a sensor (12) and a processing unit (30). The ancillary tool (2) is placed between a material (8) and the impactor (4) and transmits the impact force generated by the impactor (4) to the material (8). The sensor (12) is capable of measuring a quantity from among the impact force and the deformation of the impactor, and of supplying a measurement signal. The processing unit (30) is suitable for calculating, from the measurement signal, an indicator representative of the solidity of the material (8). The indicator corresponds to the duration of a time window between the first peak (P1) of maximum amplitude of the measurement signal and the second peak of maximum amplitude (P2).

Abstract: 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 connected 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).

Abstract: Device for inspecting the stability of a dental implant (1) in a bone (2), the implant having a free end (1a) and an end (1b) buried in the bone (2). The device comprises an ultrasonic transducer (12) for emitting and collecting an ultrasonic wave reflected from a contact interface (4) between the implant (1) and the bone (2), and providing a measurement signal representing the reflected ultrasonic wave. The device also comprises a processing unit for computing, based on the measurement signal, an indicator (IN) whose value makes it possible to evaluate the integration of the implant (1) into the bone (2). The indicator (IN) corresponds to the average energy of the measurement signal over a time interval (t1-t2) starting at a first time (t1) and ending at a second time (t2). The first time (t1) is between 20 and 80 ?s after the start of the emission of the ultrasonic wave.
