MEDIZINISCHE NADEL ZUM PENETRIEREN VON KÖRPERGEWEBE
摘要
A medical needle for endoscopic surgery has an external cannula tube in which a protective element is mounted so that it can be shifted axially against a spring. The distal, front protective surface of the protective element in a forward position projects beyond the sharp tip of the cannula tube and in a rear position is behind this tip. The protective surface of the protective element is transparent and can be observed through an optical system installed in the protective element.
