Percussion device for bone implantology and operating method thereof

Percussion device for bone implantology or surgery extraction comprising a housing body (1) within which an electromagnetic coil is installed for the acceleration of a percussion anchor (5) and from which a stem of a metal tool (2) projects, characterised in that it comprises

• a sonic rod (3) which runs through the core of said electromagnetic coil and along which said percussion anchor (5) is slidable, said sonic rod (3) comprising a terminal head (3a) with which said stem of a metal tool (2) is integrally engageable, at least in a longitudinal direction,
• a floating yoke (4) arranged in the proximity of said terminal head (3a) which acts as travel end stop for said anchor (5), and wherein
• said electromagnetic coil is overcharged with a single impulse with a current of a duration shorter than 20 milliseconds and energy ranging between 0.8-1.2 KW, so as to accelerate in a first direction and produce an impact of said anchor (5) against said yoke (4) which develops an energy transferred to said tool stem (2) through a sonic wave propagating in said sonic wave and a translational momentum, the developed force ranging between 60 and 260 daN and such impulse energy distributing for at least 80% in a time range not above 50 μs, preferably below 30 μs.
