Abstract
A medical instrument for endoscopic procedures that is provided with a hollow shaft, such that at least two channels are configured in the shaft and the channels can be coupled on the proximal end with supply conduits. To create a medical instrument of the aforementioned type which is of simple structure and ensures secure connect ability, it is proposed according to the invention that the proximal end of at least one first channel positioned in the shaft and the distal end at least one supply conduit that is to be coupled with this first channel are configured with respect to their geometric structural design in such a way that this first channel and the corresponding supply conduit can be coupled only with one another.
Claims14
A medical instrument for endoscopic procedures comprising:
- a handle and a hollow shaft,
- wherein in the handle that supports the hollow shaft at least two channels are configured extending from the shaft and the channels positioned in the handle able to be coupled on the proximal end with supply conduits,
- wherein the proximal end of at least one first channel positioned in the handle and the distal end of at least one supply conduit that is to be coupled with this first channel of the handle are configured in such a way with respect to their geometric structural design that the first channel and the corresponding supply conduit are able to be coupled only with one another,
- wherein at least two supply conduits are combined by means of a stud, which is arranged connective between the at least two supply conduits to one connecting adapter that are able to be secured to the handle by means of a coupling mechanism, and
- wherein the coupling mechanism is configured as a catch connection with the stud being configured as a part of the catch connection.
A medical instrument for endoscopic procedures comprising:
- a hollow shaft, said hollow shaft comprising at a first channel and a second channel, each said channel having a proximal end;
- a first supply conduit and a second supply conduit, each said supply conduit having a distal end,
- wherein said proximal end of said first channel is able to be coupled to said distal end of said first supply conduit, and said proximal end of said second channel is able to be coupled to said distal of said second supply conduit,
- wherein said first channel and said first supply conduit are configured in such a way with respect to their geometric structural design so that said proximal end of said first channel is not able to be coupled with said distal end of said second supply conduit,
- wherein the first and second supply conduits are arranged connective by means of a stud between the first and second supply conduits.
