PCT No. PCT/DK96/00177 Sec. 371 Date Oct. 10, 1997 Sec. 102(e) Date Oct. 10, 1997 PCT Filed Apr. 19, 1996 PCT Pub. No. WO96/32889 PCT Pub. Date Oct. 24, 1996An apparatus for the insertion of a needle guide in a patient so as to remove in an ultrasound guided manner intraoperative tissue samples (biopsies) includes a mounting member for the mounting of the needle guide on an ultrasonic transducer at the end of a catheter. The needle guide is predominantly flexible, but is rigid at the end at the mounting member. As a result, a needle inserted through the needle guide can be guided in the image plane of the ultrasonic transducer and displayed on a display unit associated with the ultrasonic transducer. The needle guide and the transducer can be operated through one and the same trocar, or each through their respective individual trocar.
