PCT No. PCT/FI86/00139 Sec. 371 Date Jul. 13, 1987 Sec. 102(e) Date Jul. 13, 1987 PCT Filed Dec. 1, 1986 PCT Pub. No. WO87/03190 PCT Pub. Date Jun. 4, 1987.The invention relates to a neurosurgical auxiliary apparatus or a brain surgery adapter (150) for neurosurgical procedures carried out through a craniotomy opening, such as imaging and/or tumor resection. The brain surgery adapter (150) comprises an adapter frame (30) arranged to be clamped and sealed (20) to the edges of the craniotomy opening (6); a preferably turnable imaging plate (70) which comprises a slide space and which is arranged to be fitted in the frame and locked in position; and an ultrasonic transducer (120) which is fitted in a transducer socket (110) provided in the slide space of the imaging plate. When the adapter according to the invention is used, the ultrasonic transducer need not be supported manually. The adapter defines a closed liquid space, and it can also be provided with instruments for performing a neurosurgical operation, such as tumor resection. Imagings are carried out by means of the brain surgery adapter according to the invention in a determined imaging plane and the obtained images are accurately determined and comparable with each other irrespective of the fact that the tissue adapts itself during the tumor resection.
