Patent ID: 8709041

Claim:
A chiropractic apparatus ( 1 ) comprising the following (i) and (ii): (i) a chiropractic adjuster ( 2 ) comprising: a thrust member ( 2 F and 2 B) extending in a longitudinal direction of said chiropractic adjuster ( 2 ) and having a thrust head ( 2 B) constituting a forward end portion of said chiropractic adjuster ( 2 ), a driving member ( 2 D and 2 E) for applying a longitudinal forward thrust to said thrust member ( 2 F and 2 B), and a trigger member ( 2 C) for operating said driving member ( 2 D and 2 E), (ii) a release-surface former ( 3 ) attached to said chiropractic adjusters ( 2 ), said release-surface former ( 3 ) having a preload surface ( 3 A) for applying a preload to a body surface (P) of a patient and, when a longitudinal forward thrust is applied to said thrust member ( 2 F and 2 B) so as to give a thrust to the body surface (P) of the patient, the thrust head ( 2 B) substantially protrudes beyond the preload surface ( 3 A) in the longitudinal direction to thereby form a release surface ( 3 B) around the thrust head ( 2 B), the transverse surface area of the thrust head ( 2 B) being smaller than the transverse surface area of the preload surface ( 3 a ).
