Claims
- 1. An endoscope, comprising:an outer shaft; an optical channel for receiving an optical system, said optical channel being arranged in said outer shaft; at least one channel arranged in said outer shaft for receiving a light supplying illumination system; a profiled shaft arranged in said outer shaft and having an outer contour configured substantially in kidney-shaped fashion, said profiled shaft being chambered in cross-section, said optical channel and said at least one channel for said light supplying illumination system being configured as chambers of said profiled shaft; a working channel for receiving a working element, said working channel being arranged within said outer shaft and outside said profiled shaft and extending from a concave outer side of said profiled shaft until an opposite concave inner side of said outer shaft; at least one longitudinal supply channel for a liquid medium, and at least one longitudinal discharge channel for discharging a medium separatedly from said supply, wherein said profiled shaft has at least two further chambers which form at least one of said at least one supply channel and said at least one discharge channel.
- 2. The endoscope of claim 1, wherein some of said chambers have not circular cross-sections.
- 3. The endoscope of claim 1, wherein said profiled shaft is removable out of said outer shaft.
- 4. The endoscope of claim 1, wherein said optical channel and said working channel have a circular cross-section, and a diameter of said chamber forming said optical channel and a diameter of said working channel for said working element are arranged on a second diameter of said outer shaft.
- 5. The endoscope of claim 1, wherein said profiled shaft has such an outer dimension that between said working channel, the inner side of said outer shaft and said profiled shaft at least one further discharge channel and/or a supply channel for a medium is arranged.
- 6. The endoscope of claim 1, wherein said profiled shaft has five chambers in its cross-section, wherein said optical channel is formed by an intermediate chamber, and said supply channel and/or said discharge channel and said channel for said light supplying illumination system is formed by chambers arranged on both sides of said optical channel.
- 7. The endoscope of claim 1, wherein said profiled shaft is configured in one piece.
- 8. The endoscope of claim 1, wherein said profiled shaft is assembled of a number of individual profiles corresponding to the number of chambers.
- 9. An endoscope, comprising:an outer shaft having a circular cross-section; an optical channel for receiving an optical system, said optical channel being arranged in said outer shaft; at least one channel arranged in said outer shaft for receiving a light supplying illumination system; a profiled shaft arranged in said outer shaft and having an outer contour configured substantially in kidney-shaped fashion, said profiled shaft being chambered in cross-section, said optical channel and said at least one channel for said light supplying illumination system being configured as chambers of said profiled shaft, wherein a convex outer side of said profiled shaft, which is in contact with said outer shaft, extends beyond the half of the inner circumference of said outer shaft; a working channel for receiving a working element, said working channel being arranged within said otter shaft and outside said profiled shaft and extending from a concave outer side of said profiled shaft until an opposite concave inner side of said outer shaft; at least one longitudinal supply channel for a liquid medium, and at least one longitudinal discharge channel for discharging a medium separatedly from said supply, wherein said profiled shaft has at least two further chambers which form at least one of said at least one supply channel and said at least one discharge channel.
- 10. The endoscope of claim 9, where in some of said chambers have not circular cross-sections.
- 11. The endoscope of claim 9, wherein said profiled shaft is removable out of said outer shaft.
- 12. The endoscope of claim 9, wherein said optical channel and said working channel have a circular cross-section, and a diameter of said chamber forming said optical channel and a diameter of said working channel for said working element are arranged on a second diameter of said outer shaft.
- 13. The endoscope of claim 9, wherein said profiled shaft has such an outer dimension that between said working channel, the inner side of said outer shaft and said profiled shaft at least one further discharge channel and/or a supply channel for a medium is arranged.
- 14. The endoscope of claim 9, wherein said profiled shaft has five chambers in its cross section, wherein said optical channel is formed by an intermediate chamber, and said supply channel and/or said discharge channel and said channel for said light supplying illumination system is formed by chambers arranged on both sides of said optical channel.
- 15. The endoscope of claim 9, wherein said profiled shaft is configured in one piece.
- 16. The endoscope of claim 9, wherein said profiled shaft is assembled of a number of individual profiles corresponding to the number of chambers.
