ABSTRACT:
A chiropractic mallet instrument for delivering a selected impact to the spinal vertebrae and or other bones of a patient in order to remove a vertebral subluxation and or other subluxations includes a tubular housing with a central handle movably supported thereon, a compression spring engaging a latch assembly and an elongate anvil member coaxially and movably fitted within an interior of the housing and extending from one end thereof, the anvil member including a distal end zone with a distal tip structured for removable attachment of various impact heads of different sizes, shapes and densities, the anvil member being axially movable relative to a longitudinal axis of the housing between a retracted, cocked position and an extended, released position. The latch assembly is operably interconnected to the central handle and carries and holds the anvil member in the retracted, cocked position upon movement of the central handle towards a palm handle on an opposite end of the housing. Application of pressure to the distal tip actuates a trigger mechanism, releasing the latch assembly and anvil member, causing the compression spring to urge the anvil member rapidly to the extended, released position. A guide element is selectively positionable within one of three directional grooves in the distal end zone to control rotation of the anvil member when moving to the extended, released position, so that the impact head delivers either a straight axial force or a clockwise or counter clockwise torsional force on impact.
