Abstract
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.
Claims13
A medical instrument for injecting liquid into a hollow organ and/or drawing off liquid from a hollow organ, such as a bile duct comprising:
- a shaft;
- a hollow needle which can be inserted at a free end thereof into the hollow organ via an entrance opening of the organ, said needle being mounted within said shaft;
- and
- clamping means associated with the hollow needle and mounted within said shaft for enclosing the tissue of the hollow organ, said clamping means for clamping at least between an entrance opening of the hollow organ and an outlet opening of the hollow needle at said free end thereof so that no liquid can escape between the tissue and the hollow needle;
- wherein said free end of the hollow needle includes a curved insertion region and the tissue can be sealed against the hollow needle in the curved insertion region of said needle by said clamping means.
