DISPOSITIVO DI CENTRATURA E GUIDA DI BIOPSIE PROFONDE TORACO-ADDOMINALI TC GUIDATE

A centring and guidance system for the performance of deep CAT-guided thoraco-abdominal biopsies is described. The device, which is made of radiotransparent material, is located on the patient's supporting bed of the CAT equipment or connected to it and therefore can be introduced into the zone affected by the rays together with the patient, thus rendering the operation of introducing the needle easier. The needle, of variable gauge and length, is connected to a removable and sterilizable guide which is of one piece with the device and which can be orientated and positioned in any way with respect to the patient. The advantages of the procedure performed using the device according to the invention can be evaluated in terms of accuracy and the reduction in complications in view of the single pass of the needle brought about by the controlled route and the possibility of planning the route with respect to critical organs.
