Abstract

A chiropractic adjusting instrument comprising a housing; a thrust nose piece and an impact head to contact a body; a preload switch plunger; a dampening spring; a solenoid having a core; a preload spring; a recoil spring; 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 which is reproducible and independent of the power source; and a trigger system for triggering the electronic pulse system comprising an switch activated by the preload switch plunger. Preferably, the chiropractic adjusting instrument includes one or more of the following: an intelligent universal AC power converter; optimized force-time waveform; pulse mode operation; and a suite of electromechanical components designed to promote reproducible dynamic force impulses and safe operation.

Claims

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.

2. The chiropractic adjusting instrument as recited in claim 1 further comprising a shock absorber having a shock absorber passage between the core and the third inner stop.

3. The chiropractic adjusting instrument as recited in claim 1 further comprising a coupler having a coupler inner passage to accept the preload switch plunger and interposed between the recoil spring and the preload switch plunger, and wherein the core further comprises a coupler end adapted to couple with the coupler.

4. The chiropractic adjusting instrument as recited in claim 3 wherein the coupler is made of nonconductive material.

5. The chiropractic adjusting instrument as recited in claim 4 wherein the nonconductive material is selected from the group consisting of nylon and TEFLON.

6. The chiropractic adjusting instrument as recited in claim 1 wherein the thrust nose piece further comprises a preload shank having the preload end adapted to couple with the preload switch plunger.

7. The chiropractic adjusting instrument as recited in claim 1 wherein preload switch plunger made of materials selected from the groups consisting of metals, nonconductive plastics and combinations thereof.

8. The chiropractic adjusting instrument as recited in claim 1 wherein the housing is gun shaped.

9. The chiropractic adjusting instrument as recited in claim 1 wherein the power source is a single phase alternating current electricity having a voltage between 90 and 265 volts and a frequency between 50 and 60 hertz.
