Abstract
A cervical traction tong assembly for mounting cranial pins to the head of a spinal fracture patient. The cervical tong assembly includes an arcuate central support member having a pair of movable coupling assemblies connected to the ends thereof for radial movement relative to the central support. A pair of straps for carrying cranial pins are rotatably mounted to each of the coupling assemblies. The coupling assemblies and the rotatable straps may be adjusted to position cranial pins at desired locations upon a patient's head and to provide a traction force vector at any predetermned angle.
Claims6
An orthopedic traction tongs assembly for attachment to the head of a user patient by cranial pins for applying tension to the patient's head at selected vector angles measured with reference to a first imaginary axis line extending vertically upward through the center of the patient's head and a second imaginary axis line which orthogonally intersects the first line and extends through the center of the patient's head from front to back, comprising:
- main support means formed generally in the configuration of a rigid arc for extending from one side of the patient's head over the top of the patient's head to the other side thereof;
- a first coupling assembly connected to a first end of the main support means;
- a second coupling assembly connected to the second end of the main support means each coupling assembly being movable on the main support means, generally radially inwardly or outwardly in relation to the arc formed by the main support means;
- means for securing each coupling assembly to each end of the main support means, allowing each coupling assembly, to move on the main support means, generally radially inwardly or outwardly in relation to the arc formed by the main support means;
- a pair of pin support means connected to each of the first and second coupling assemblies for mounting cranial pins for attachment to the patient's skull, at least one of the pin support means being rotatably mounted to its coupling assembly for permitting attachment of the cranial pin, mounted to the rotatable pin support means, at a selected location on the patient's skull;
- and
- a cranial pin, mounted to the rotatable support means, which provides tension at a selected location on patient's skull.
