The present invention relates to a head clamp. More specifically, a head clamp for fixing the head of a patient for a surgical operation or examination, comprises: a coupling plate which is coupled to one end of a table for supporting the body of the patient a longitudinal axis frame of which the end of one side is coupled to an end at the center of the coupling plate, and the lengthwise direction of which is parallel to a first axial direction, which is in a longitudinal direction a latitudinal axis frame of which the lengthwise direction is in a latitudinal direction, and which is parallel to a second axial direction that is perpendicular to the first axial direction a length adjustment portion, which is provided between the longitudinal axis frame and the latitudinal axis frame, for guiding the longitudinal frame so as to shift in the first axial direction and shift the latitudinal frame in the second axial direction arms, each of which has an end on one side that is coupled to ends on both sides of the latitudinal frame pin holder devices which are coupled to each end on the other side of the arms, respectively and pins, each of which is coupled to the pin holder device, for coupling the head between the arms, thereby allowing an integrated body comprising the arms and the latitudinal frame to enter the inside of a gantry while the head is fixed by means of the pins.La présente invention concerne un blocage de tête. De façon plus spécifique, un blocage de tête, pour fixer la tête dun patient pour une intervention chirurgicale ou un examen chirurgical, comprend : une plaque daccouplement qui est couplée à lune des extrémités dune table pour supporter le corps du patient un cadre daxe longitudinal dont lextrémité de lun des côtés est couplée à une extrémité au centre de la plaque daccouplement, et dont la direction selon la longueur est parallèle à une première direction axiale, qui est dans une direction longitudinale un cadre daxe latitudinal dont la direction
