Orthopedic tongs

Claim 1

Orthopedic traction tongs for applying tension at selected vector angles, measured with reference to an imaginary axis line extending vertically upwardly through the center of the head of a user patient when the tongs are in use, for being attached to the head of the user patient when in use by cranial pins, comprising the combination of: main support means generally in the configuration of a rigid arc so constructed and configured as, when in use, to extend from side of the user patient's head over the top to the other side of the user patient's head; a pair of pin support means for securing cranial pins to the orthopedic traction tongs, each pin support means comprising a generally arcuate member extending from the ends of the main support means, when in use, partially around the head of the user patient for permitting cranial pins to be inserted into the skull of the user patient at radially spaced intervals; tension applying means positioned between the two ends of and on the main support member; means for selectively attaching the tension applying means at any preselected position generally centrally of the main support member, for applying, when in use, tension at a preselected angle, measured with reference to the imaginary axis line, side-to-side and front-to-back of the head of the user patient; and rod connecting means secured to the respective ends of the main support means for securing fixation rods to the traction tongs for applying force through said rods to said main support means, said rod connecting means each comprising a pair of relatively rotatable clamp elements and means for securing said clamp elements to each other in a fixed relationship for thereby applying said force as tension to the head of the user patient at a preselected angle measured, when in use, with reference to said imaginary line from front-to-back of the head of the user patient.
