Abstract: A head stabilization device useable for stabilizing a head of a patient during a medical procedure includes a modular design where stabilization assemblies of various configurations are interchangeable at receiving portions along a frame. The device includes a tensioning feature positioned away from the stabilization assembly but still operable to increase or decrease an amount of force the stabilization assembly applies to the patient's head. The device includes a locking feature for a stabilization assembly having a rotatable member having one or more stabilization features connected thereto. The device includes an adjustment feature to adjust a spacing between frame members with the adjustment feature providing a continuous range of adjustment rather than finite adjustment increments.

Abstract: A head stabilization device includes a stabilization assembly and an applicator to control an amount of force that a stabilization feature applies to the head of the patient. The applicator includes a torque control feature that ensures a desired torque setting is not exceeding during use. The applicator can be detached from the remainder of the system such that the head stabilization device is usable without having a connected torque controlling feature or structures. The applicator in one version controls torque by adjusting a bending length of a pair of arms that extend within the applicator.

Abstract: A head fixation device includes an assembly with two or more contact features. The assembly includes an arm that is non-curved in some versions. In some versions, the arm of the assembly defines a degree of curvature that is less than 40 degrees, and more preferably less than 30 degrees. In at least some versions, the assembly provides that at least two of the two or more contact features define a contact angle with the skull of about 90 degrees when contacting a generally or substantially planar portion or region of the skull.

Abstract: A fixture for immobilizing a patient's head during a medical procedure is usable with a CT scanner. The fixture includes a skull clamp having detachable and adjustable radiolucent extensions. The radiolucent extensions include a body portion, a surgical pin holder assembly, and an attachment member. A first radiolucent extension includes a two-pin holder assembly. A second radiolucent extension includes a single-pin holder assembly. The attachment member of the radiolucent extension allows for angular adjustable attachment of the radiolucent extension to the skull clamp through corresponding starburst features. The surgical fixture may include an immobilization base unit having first and second mounting arms, a connecting arm, and a position adapter. The skull clamp with extensions attaches to the immobilization base unit to further immobilize the patient. The position adapter connects to the skull clamp and includes a rotational unit and vertical adjustment unit to position the patient as desired.
