摘要

Medical instrument for injecting liquids into a hollow organ and/or drawing off liquids from a hollow organ, in particular a bile duct. Clamping apparatus are associated with the hollow needle of the instrument, this instrument being constructed as a tubular shaft, and the tissue of the hollow organ can be securely enclosed by these clamping apparatus between an entrance opening in the hollow organ and an outlet opening of the hollow needle in such a way that no liquid can escape between the tissue and the hollow needle.
