Head stabilization system and method with cassette features

A medical device configured for supporting and stabilizing a head of a patient during a medical procedure, the medical device comprising:

• (a) a positioning assembly defining an axis of rotation, wherein the positioning assembly includes a selectively rotatable portion that is rotatable about the axis of rotation and is configured to adjust a rotational position of the selectively rotatable portion of the positioning assembly relative to the head of the patient;
• (b) a head support configured to directly or indirectly adjustably connect with the positioning assembly such that the head support is translatable independent from and relative to the positioning assembly and rotatable in unison with the selectively rotatable portion of the positioning assembly, wherein the translation and rotation of the head support is configured to permit changing a position of the head support relative to the head of the patient;
• and
• (c) a body receivable by the positioning assembly, wherein the body is selectively translatable relative to the selectively rotatable portion of the positioning assembly, wherein the positioning assembly comprises a connector and an actuator, wherein the actuator is configured to selectively secure:
• (a) a translational position of the body relative to the selectively rotatable portion of the positioning assembly;
• (b) the rotational position of the selectively rotatable portion of the positioning assembly relative to the connector;
• and (c) a translational position of the selectively rotatable portion of the positioning assembly relative to the connector.

• (b) a skull clamp configured to directly or indirectly adjustably connect with the positioning assembly such that the skull clamp is translatable independent from and relative to the positioning assembly and rotatable in unison with the selectively rotatable portion of the positioning assembly, wherein the translation and rotation of the skull clamp is configured to permit changing a position of the skull clamp relative to the head of the patient;
• and
• (c) a central head support connectable with the positioning assembly, wherein the central head support is configured to provide subjacent support to the head of the patient, wherein the central head support comprises a slot, wherein a connector of the positioning assembly is receivable within the slot and adjustable along or parallel to a first plane defined by the central head support that extends subjacent to the head of the patient when the head of the patient is supported by the central head support to change a position of the positioning assembly relative to the central head support.
