The working principle is as follows:
the instrument passage tube is mounted in a guide tube 5 of an endoscope, and the guide tube 5 of the endoscope has an insertion section 51, a passive bending section 52, and an active bending section 53. When the endoscope handpiece 4 is manipulated, the active bending section 53 can bend accordingly, while the passive bending section 52 can bend actively under pressure. Because the utility model discloses a screwed pipe 21 is located the tip position of endoscope pipe 5, then screwed pipe 21 can overlap with the active bending section 53 and the passive bending section 52 of endoscope pipe 5, when the pipe 5 active bending of endoscope or passive bending, screwed pipe 21 can corresponding bending, and screwed pipe 21 can not produce and sink, then the apparatus passageway pipe can not sink. When the endoscope guide tube 5 is bent, the instrument channel tube in the guide tube 5 can not collapse all the time, so that the instrument can smoothly pass through the instrument channel tube, and the instrument can accurately obtain tissues, sample tissues for biopsy, or single tissues and the like.
The present invention is not limited to the above-mentioned optional embodiments, and any other products in various forms can be obtained by anyone under the teaching of the present invention, and any changes in the shape or structure thereof, all the technical solutions falling within the scope of the present invention, are within the protection scope of the present invention.
