摘要：
A device (1) assisting with the placement of an orthopedic instrument (2) intended to be inserted in a receiving bone (3) by impaction, by means of an impacter (10) comprising at least one striking surface (11) designed to come into contact with an impact surface coupled to said orthopedic instrument in order to apply an impaction force to said orthopedic instrument (2), said device being characterized in that it comprises a force sensor (12) able to measure, upon each impact, said impaction force applied by the impacter (10) to said impact surface and to supply a measurement signal indicative of the temporal variation of said applied impaction force, said force sensor (12) being connected to processing means (30) designed to determine, on the basis of the temporal variation of said impaction force supplied for each impact in succession, an indicator representative of the degree of insertion of said orthopedic instrument (2) in the receiving bone (3).
