Mechanical guide means for point ion devices in the ultrasonically controlled puncture

摘要

Mechanical auxiliary guide means for the secure fixing and guidance of a puncture needle to an ultrasound head which is configured in such a way that they are laterally with an accurate fit to an ultrasound head movement is mounted in a stable manner and which has a large-area recess, which are exactly with the extension of the sound level of the ultrasound head, which is limited in smooth-walled manner, the lateral limitation in the vertical, as well as in the horizontal direction to extend in parallel and whose thickness is dependent on the diameter of the puncture needle is that a slide unresisted movement, and there is no lateral tilting of the puncture needle, which is guided in the recess is possible.
