Abstract
Provided are an apparatus and method for sterilizing an internal channel surface of an endoscope, and more particularly, to an apparatus and method for sterilizing an internal channel surface of an endoscope, in which ultrasonic and infrared rays are irradiated to an internal channel of the endoscope to partially or entirely sterilize and removing a biofilm generated on the internal channel surface of the endoscope during a procedure or diagnosis.
Claims12
An apparatus for sterilizing an internal channel surface of an endoscope, the apparatus comprising:
- an ultraviolet light source configured to irradiate ultraviolet rays;
- an infrared light source configured to irradiate infrared rays;
- a porous catheter configured to be inserted into the endoscope;
- a pull-back driver configured to move an optical fiber forward and backward;
- the optical fiber passing through the pull-back driver and disposed in the porous catheter to irradiate the ultraviolet rays and the infrared rays to a surface of the inside of the endoscope;
- a coupling part configured to couple the ultraviolet rays and the infrared rays to output the coupled rays having wavelengths of the ultraviolet rays and the infrared rays to the optical fiber;
- and
- an injection tubing coupled to the porous catheter and configured to transfer a sterilant to the porous catheter.
