<p>One aspect of the present invention provides a surgical headframe (10) for maintaining a stereotactic system reference frame relative to a patient's head. The headframe includes a frame body (12), first and second arms (14a,b), a plurality of contact pads (18a,b,c), and a strap (16). The first and second arms (14a,b) extend from opposing sides of the frame body (12), respectively. The plurality of contact pads (18a,b,c) are coupled to the frame body (12) and are each adapted to engage a patient's head. Finally, the strap (16) is selectively connectible to the first and a second arms (14a,b). In this regard, the strap (16) is adapted for wrapping about a back of a patient's head. With this construction, the surgical headframe (10) is capable of precisely positioning and fixating the reference frame (130) to the patient's head during these stereotactic procedures, without requiring bone screws, bone pins or clamps. In one preferred embodiment, three contact pads (18a,b,c) are provided, and are arranged in a tripod-like fashion. In a further preferred embodiment, the contact pads (18a,b,c) are pivotally coupled to the frame body (12), and are co-planer. With this preferred construction, the headframe (10) is highly stable when applied to the patient's head. In yet another preferred embodiment, a control pad (132) is mounted to the frame body (12).</p> |
