Abstract
An apparatus and method are provided for restricting movement of a patient's head. The apparatus includes a frame and a plurality of constraints engaged with the frame to exactly constrain the patient's head relative to the frame.
Claims12
An apparatus for restricting movement of a patient's head, the apparatus comprising:
- a frame;
- and
- a plurality of constraints engaged with the frame to exactly constrain the patient's head relative to the frame, wherein the plurality of constraints includes a first constraint engaged with the frame to permit exactly three degrees of motion of the patient's head relative to the frame, a second constraint engaged with the frame to permit exactly four degrees of motion of the patient's head relative to the frame, and a third constraint engaged with the frame to permit exactly five degrees of motion of the patient's head relative to the frame.
An apparatus for restricting movement of a patient's head, the apparatus comprising:
- a frame;
- and
- a plurality of constraints engaged with the frame to exactly constrain the patient's head relative to the frame, wherein the plurality of constraints includes a constraint engaged with the frame to permit exactly five degrees of motion of the patient's head relative to the frame, wherein the constraint includes:
- a first member engaged with a portion of the frame to move generally along an axis;
- and
- a second member configured to pierce the patient's head and embed in the patient's skull, the second member engaged with the first member to move transversely to the axis.

- a sleeve engaged with a portion of the frame, the sleeve defining a cavity;
- a first member defining a slot that is received within the cavity;
- and a second member that is movably engaged with the first member within the slot, wherein the second member of the constraint defines a first aperture;
- the constraint further includes a third member positioned within the first aperture;
- and the third member is configured to pierce the head of the patient and embed in the skull, and wherein the sleeve further defines a second aperture;
- the constraint further includes a third member within the second aperture;
- and the third member abuts the first member.
