ABSTRACT:
A device for providing precise incremental joint movement in a patient, includes first and second spaced retractors for engaging respective parts of the patient adjacent the joint. One of the retractors is mounted on a fixed support assembly and the other retractor is mounted on a movable actuation rod slidably mounted in the support assembly. The device is formed entirely on non-magnetic material and is readily operable by the patient, making the device especially useful in magnetic resonance imaging procedures. The retractors are of a construction such that they can be snapped onto the support assembly and the actuating rod, respectively, and then ruptured upon being removed therefrom, so as to prevent inadvertent use of the retractors on another patient. An operating mechanism for the actuating rod includes a handle-operable pawl, and a retaining mechanism for the actuating rod includes a spring-biased holding pawl, which can be pivoted to release the actuating rod so that it can be readily returned by hand by an initial closed position.
