Abstract

The invention refers to an endoscope including at least one channel which may be contaminated in use, wherein the channel wall of the at least one channel is formed of a material having properties capable of photocatalysis. The invention further refers to a method for cleaning such an endoscope including the steps of: connecting the endoscope to a reprocessing device, performing a photocatalytic treatment at least in the at least one channel for the purpose of the decomposition of organic residues on the surface of the channel, and rinsing the endoscope. The invention further refers to a cleaning device for cleaning such an endoscope.

Claims (21)

1. An endoscope system comprising:

at least one channel which may be contaminated in use,

the at least one channel comprising an inner wall of the at least one channel formed of a material having properties capable of photocatalysis;

an ultraviolet probe configured to move through the at least one channel and emit ultraviolet radiation that provides photocatalytic treatment of the inner wall of the at least one channel; and

at least one adaptor removably connectable to a respective said at least one channel, each said at least one adaptor having a first inlet configured to supply fluid to each respective said at least one channel, and further having a second inlet configured to accommodate the ultraviolet probe therein.

2. The endoscope system according to claim 1 , wherein

the inner wall of the at least one channel is made of plastic to which a photocatalyzable substance is added.

3. The endoscope system according to claim 1 , wherein

the inner wall of the at least one channel is made of plastic which is compounded with a photocatalyzable substance.

4. The endoscope system according to claim 1 , wherein

the inner wall of the at least one channel is coated with a photocatalyzable substance.

5. The endoscope system according to claim 1 , wherein

the photocatalyzable material is titanium oxide.

6. The endoscope system according to claim 1 , wherein

the photocatalyzable material is titanium oxide in anatase modification.

7. The endoscope system according to claim 1 , wherein

the photocatalyzable material is titanium oxide in an anatase-rutile mixture.

8. The endoscope system according to claim 1 , wherein

a UV stabilizer and/or a thermostabilizer are added to the photocatalyzable material.

9. The endoscope system according to claim 2 , wherein

the plastic is flexible polyether ether ketone or polyamide.
