Abstract

A frame for fixation of equipment to the head of a patient during neurological diagnosis, therapy or surgery is adapted to enclose the head of the patient. The frame includes a number of mounting slots arranged in the frame. The mounting slots are adapted to receive a number of fixation pins adapted to fixate the frame to a bone in the head. The frame further includes two anterior longitudinal posts and two posterior longitudinal posts, extending along a longitudinal axis A, an anterior portion, adapted to be arranged at the anterior side of the head, the anterior portion interconnecting the two anterior longitudinal posts, and a posterior portion, adapted to be arranged at the posterior side of the head, the posterior portion interconnecting the two posterior longitudinal posts. The anterior longitudinal posts and the posterior longitudinal posts are interconnected with two lateral portions, adapted to extend one on each side of the head, and wherein the lateral portions are axially offset, along the longitudinal axis A, with respect to the anterior and posterior portion. A stereotactic frame system includes such a frame.
