Adjustable immobilizer apparatus and method for immobilizing a patient
Systems for immobilizing a patient are disclosed. The system includes at least one preform formed from a low melting temperature thermoplastic, the preform being configured to be formed to the anatomy of the patient, at least one frame coupled to the at least one preform, and at least one support configured to support the anatomy of the patient. The system also includes at least one lock mechanism coupled to at least one of the frame and the support and configured to couple the at least one frame to the at least one support, and at least one adjuster mechanism coupled to at least one of the at least one frame and the at least one support and configured to selectively adjust a distance between the at least one frame and the at least one support while the at least one frame is coupled to the at least one support.
1. An apparatus for immobilizing an anatomy of a patient, the apparatus comprising:
a frame;
a preform formed from thermoplastic and configured to be formed to an anatomy of a head of the patient, the preform coupled to the frame;
a support configured to support the anatomy of the patient;
a lock coupled to at least one of (i) the frame and (ii) the support and configured to couple the frame to the support;
an adjuster coupled to at least one of (i) the frame and (ii) the support, the adjuster configured to be rotated to adjust a distance between the frame and the support,
wherein the adjuster comprises an index configured to index rotation of the adjuster and defining discrete positions, each discrete position corresponding to a relative distance between the frame and the support.
2. The apparatus of claim 1 , comprising a plurality of the adjuster, the plural adjusters each coupled to the support and spaced from one another, such that a distance between the frame and the support at one of the plural adjusters is adjustable independent of a distance between the frame and the support at another one of the plural adjusters.
3. The apparatus of claim 1 , wherein the adjuster is configured to adjust the distance between the frame and the support while the lock is coupling the frame to the support.
4. The apparatus of claim 1 , wherein the adjuster is coupled to the support.
5. The apparatus of claim 4 , wherein the adjuster is positioned on the support.
6. The apparatus of claim 5 , wherein the adjuster is integrated into the support.
7. The apparatus of claim 1 , wherein the adjuster comprises a knob which is rotated to adjust the distance between the frame and the support.
8. The apparatus of claim 1 , further comprising one or more visual indicators associated with the adjuster that indicate the distance between the frame and the support.
9. The apparatus of claim 1 , wherein the frame is a split frame comprising two separate frame sections connected by the preform, wherein the two separate frame sections are not directly connected to one another other than by the preform.
