1. A chiropractic adjusting instrument comprising:

  • a housing having an opening;

    a thrust nose piece movably mounted in the housing and comprising a preload side and an outer end including an outer end shank for coupling to at least one impact head wherein the opening allows the coupled outer end shank impact head to contact a body;

    a preload switch plunger coupled to a preload end of the thrust nose piece;

    a dampening spring interposed between the housing and the outer end of the thrust nose piece or a first inner housing stop having a first passage to accept the thrust nose piece;

    a solenoid mounted in the housing and comprising;

    a longitudinal axis and a core having a third passage to accept the preload switch plunger so that the core is movable along the longitudinal axis and is in alignment with the thrust nose piece;

    a preload spring interposed between the preload side of the thrust nose piece and a second inner housing stop having a second passage sufficient to accept the coupled preload switch plunger preload end;

    a recoil spring interposed between the core and the coupled preload switch plunger preload end;

    a third inner stop to prevent the normal urging of core away from the coupled preload switch plunger preload end and having a fourth inner passage to accept the preload switch plunger;

    an electronic pulse system operatively connected to a power source to provide alternating current for energizing the solenoid to impart impulse energy from the core to the thrust nose piece that is reproducible independent of the power source;

    a trigger system for triggering the electronic pulse system comprising a switch activated by the preload switch plunger.
