Further, better drainage effect, on the silica gel pipe side opening interval is 3cm, and the side opening interval of first hunch portion and second hunch portion is 0.5 cm.

Further, for better male and female patient's travelling comfort, the length of the straight section of silica gel pipe is 26 and 28cm, the interior width of first hunch portion and second hunch portion is 1 cm.

Further, the first and second wires have a wire diameter of 0.2mm for better somatosensory perception, less irritation and reduced infection of the patient.

Further, in order to conveniently keep the ureteral stent tube in the operation, the length of the first silk thread is 50cm, and the tail end of the first silk thread is knotted in a natural fishing mode.

Furthermore, the second silk thread (6) is 25cm long, and single line fishing is performed by knotting the upper end of the second silk thread for better tube drawing effect and prevention of line dropping.

Further, for wider medical purposes, the lumen models of the silica gel round tubes are F4, F5, F6 and F7.

The utility model discloses an optimized ureter drainage stent tube, without the direct extubation of cystoscope, amazing little, can not increase advantages such as infection chance, multiple medical usage.

Compared with the prior art, the utility model provides a ureter drainage stent possesses following beneficial effect:

1. the ureter drainage stent keeps the second silk thread (6), and the ureter drainage stent is directly used without drawing a cystoscope.

2. The ureter drainage stent adopts the thin silk thread, has less stimulation to patients, can not increase the infection chance, and has no obvious foreign body sensation.

3. The ureter drainage stent does not need to be directly pulled out under a cystoscope, can guide a patient to pull out the catheter by himself or can be used as a common ureter stent, and has wider application.

4. The ureter drainage stent is used by over 600 different patients, and the stent tube is reserved under a ureteroscope and a cystoscope, so that 100 percent of patients can be pulled out without the cystoscope. The ureteral stent tube is kept under the percutaneous nephroscope, and the second silk thread (6) can be automatically discharged by 100 percent of female patients and about 70 percent of male patients to directly pull out the tube.

Detailed Description

The technical solution in the embodiment of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiment of the present invention; obviously, the described embodiments are only a part of the embodiments of the present invention, and not all embodiments, and all other embodiments obtained by those skilled in the art without any inventive work are within the scope of the present invention based on the embodiments of the present invention.

It will be understood by those skilled in the art that, unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. It will be further understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the prior art and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein.

Example 1:

referring to fig. 1-2, a ureter drainage stent tube comprises a silica gel stent tube and silk threads connected with at least one end of the silica gel stent tube, wherein the silica gel stent tube comprises a straight silica gel circular tube 1, a first arch part 2 and a second arch part 3, two ends of the silica gel circular tube 1 are bent at the same side, side holes 4 are formed in the two side tube walls of the first arch part 2 and the second arch part 3 at intervals, and the silk threads for knotting are arranged at the tail ends of the first arch part 2 and the second arch part 3 in a penetrating mode.

More specifically, the filaments include a first filament 5 and a second filament 6.

More specifically, the distance between the side holes on the silica gel round tube 1 is 3cm, and the distance between the side holes on the silica gel round tube 4 is 0.5 cm.

More specifically, the length of the straight section of the silica gel round tube 1 is 26 and 28cm, and the inner width of the first arch part 2 and the second arch part 3 is 1 cm.
