title: [Modification of the vacuum extraction device (author's transl)].
abstract: The article describes a bell-shaped vacuum extractor with a rigid tube neck connected via a ball and socket joint. The advantages of this device over the "classical" device described by Malmström (2), are as follows: Easier insertion of the bell adjusted at an angle of 90 degrees, improved pushing-up of the bell for fastening to the head when this is still in elevated position, better placing of the bell at the desired location, better manipulation into the desired direction of pull, possibility of pushing up the anterior part in case of late cesarean section, and better sealing of the suction tube at the point of transition from the tube to the flexible hose. Another improvement concerns the adhesion, achieved by means of ring-shaped notches on the inside of the bell.
