Head stabilization system and method with cassette features

A head stabilization device for stabilizing a head of a patient, the stabilization device comprising:

• (a) a pair of extension bars extending from a base assembly;
• (b) a pair of ratchet features, wherein each one of the pair of ratchet features is in mechanical communication with one of the pair of extension bars, wherein the ratchet features are configured to selectively adjust the pair of extension bars laterally relative to a central axis of the device;
• (c) a pair of pads, wherein each one of the pair of pads is connectable with one of the pair of extension bars, wherein each one of the pair of pads comprises a first chamber filled with a fluid and a second chamber filled with a granular material, wherein the first chamber is configured to impinge upon the second chamber such that the granular material within the second chamber is configured to conform to the head of the patient;
• and
• (d) a pressure application and indication feature configured to provide fine adjustment of the contact pressure between the pads and the head of the patient.

A medical device for supporting and stabilizing a head of a patient during a medical procedure, wherein the medical device is configured to prevent slippage during supporting and stabilizing the head of the patient, the medical device comprising:

• (a) a central head support configured to connect with an operating table directly or indirectly via one or more intermediate structures, wherein the central head support is further configured to provide subjacent support to the head of the patient, wherein the central head support comprises a cushion configured to contact the head of the patient;
• (b) a positioning assembly connectable with the central head support;
• and
• (c) a skull clamp configured to adjustably connect with the positioning assembly such that the skull clamp is translatable relative to the positioning assembly, and wherein the skull clamp is further rotatable relative to the central head support, wherein the translation and rotation of the skull clamp permits changing a position of the skull clamp relative to the cushion of the central head support.
