Abstract
Abstract A distraction pump for manipulation of the spinal column and associated bodily structures having a pump body and two arms coupled to the body, one of the arms being movable relative to the other arm. Each arm has displacement means coupled to it. The distraction pump has a handle that is movable between a non-actuated position and an actuated position and actuator means operatively for causing the two displacement means to be moved from a first relative position when the handle is in the non-actuated position to a second relative position when the handle is in the actuated position.
