An apparatus and method are disclosed for displaying a path between a selected target and selected points on a patient's skull and for guiding surgical instruments along any selected path. The system is comprised of an image display system, an articulated arm and probe, and a stereotactic system. The sub-systems are coupled to one another so that the articulated probe may be used to select patient fiducial points that correspond to selected image fiducial points. Using these points, the image display system coregisters the external locations to the displayed images so that the probe condition may be displayed with the displayed images. The system further permits the identification of a selected target within a patient's brain and to project a path from the external position to the target prior to the performance of a craniotomy. After evaluation of the path, a surgeon may lock the stereotactic system in place to preserve a selected surgical path and to guide instruments along that path. A method of utilizing the system to perform such surgical procedures is also described.

A locking mechanism for securing a container to a truck chassis is provided and includes a manually reciprocating locking member movable in a piston-like fashion through a housing from a retracted position within the housing to an extended position within a slot of a corner casting in an adjacent container. The reciprocating member is also rotatable and includes an eccentric locking pin to adjust the location of the locking pin to compensate for dimensional variations and to enable the locking pin search for the locking slot of a corner casting by moving between several positions.

A head support for a patient support table having a skull securing clamp that is mounted to a non-circular support bar for selective attachment to the side rails of the patient support table. The skull clamp includes a non-circular support aperture for receiving the non-circular support bar. The structural components of the head support are made from radiolucent material and the support bar includes mounting posts at its first and second ends so that arms for mounting the support bar to the side rails may be located out of the path of the x-rays through the patient's head. The non-circular shape of the support aperture and the support bar prevent inadvertent rotation of the radiolucent skull securing clamp with respect to the radiolucent support bar. The location of the mounting posts on the support arms and the utilization of the radiolucent material results in fewer artifacts in the developed x-ray picture.
