Patent attributes
A head support base unit enables enhanced capability for positioning the head of a patient at the end of a medical table, by incorporating into the handle assembly thereof an additional degree of freedom, namely rotatability along the longitudinal axis of the handle. More specifically, a pair of axially opposed, spring-biased ratchets are housed within the handle, to permit or prevent axial rotation of one end of the handle relative to the other. This enhanced flexibility an maneuverability is achieved without any added complexity, and without requiring any additional space. These advantages are further magnified if an additional like handle assembly is connected to the first handle assembly, with a link interconnected therebetween, because composite angles and off-axis positioning of the patient can be readily accommodated.
