A medical head holder includes at least two opposing engagement members configured to engage the head of a patient, a frame, connector and coupling members, and a force applicator. The frame includes first and second frame sections which are displaceably coupled with each other, wherein each frame section supports at least one of the engagement members. The connecting member guides the first and second frame sections for displacement relative to each other, and selectively detachably fixes the frame sections with each other. The coupling member is selectively fixed to the second frame section and displaceably couples the second engagement member with the second frame section. The force applicator is detachably coupled to the second frame section and acts on the coupling member so as to cause the second engagement member to be displaced and/or fixed relative to the second frame section.

Medical head holder

The fastening device in accordance with the invention is directed to a pin for securing the position of a part of a body, (for example, a head) for medical procedures. The fastening device can have an improved geometry, can be made from materials including unsubstituted, monosubstituted or multisubstituted polyphenylene, and/or silicon nitride ceramic, and can be made of one or more pieces. The fastening device in accordance with the invention produces improved performance with respect to the criteria of biocompatibility, ability to be sterilized, resistance to mechanical stress, and reduced artifact creation in medical imaging methods.
