Abstract
An apparatus to introduce impact pulses into the human body has an impact transmitter (8) displaceable in an axial direction and an electromagnetic impact generator (2, 6; 26, 24; 36, 34) driven by current pulses and supplying force impulses to the impact transmitter. The impact generator includes a magnet fixed in position and having a magnetic field, and a coil (6, 26, 36) displaceable in the direction of transmitter displacement in the field of the magnet (2; 23, 24; 33, 34), the coil being energized by the current pulses to be axially displaced and drive the impact transmitter (8).
Claims9
An apparatus to introduce impact pulses into the human body comprising
- an impact transmitter (8) displaceable in an axial direction;
- a source of current pulses;
- an electromagnetic impact generator (2, 6;
- 26, 24;
- 36, 34) driven by current pulses from said source and supplying impact impulses to said impact transmitter, said impact generator comprising
- a magnet fixed in position and capable of producing a magnetic field, and
- a coil (6, 26, 36) displaceable in said direction of transmitter displacement in said field of said magnet (2;
- 23, 24;
- 33, 34), said coil being energized by said current pulses to be axially displaced and drive said transmitter (8).
