Abstract
An endoscope has an outer shaft, in which an optical channel receiving an optical system is arranged, wherein in the outer shaft, further, a channel for receiving a working element, at least one supply channel extending longitudinally for a medium and at least one discharge channel extending longitudinally for the discharge of a medium, the discharge being separated from the supply, are arranged. The optical channel and the at least one supply channel and/or the at least one discharge channel are configured as chambers of a profiled shaft, which is chambered in its cross section and received in the outer shaft.
Claims16
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.
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.
