Referring to fig. 2, fig. 2 is a schematic view of the structure of the apparatus for preventing ureteral skin stoma stenosis after a total bladder operation when a needle tube is withdrawn. When the distal ends of the needle core device 1 and the third-stage internal part catheter 23 are separated, the third-stage internal part catheter 23 forms a bacterial expansion part under the action of self deformation force, and the radial dimension of the side of the bacterial expansion part close to the skin is larger than the dimension of the side of the bacterial expansion part far away from the skin; the first section of external part catheter 21 is elliptical in natural state, and the radial dimension of the first section of external part catheter 21 is larger than that of the second section of external part catheter 22; the length of the first section of external part conduit 21 is 0.5cm, and the radial dimension specification is FR8-FR10; the second section of skin portion catheter 22 is 2cm long and has a radial dimension FR6; the length of the third section of internal part conduit 23 is 1-2cm, and the radial dimension of the third section of internal part conduit 23 forming a bacterial expansion part is FR12-FR14.
It should be noted that:

When the core device 1 collides with the distal end of the third-section internal part catheter 23, the third-section internal part catheter 23 becomes longer, and the specific principle is as follows: when the distal end of the third-stage inner catheter 23 of the core device 1 abuts against the distal end, the human hand gives forward pushing force to the core device 1 and simultaneously fixes the first-stage outer catheter 21, so that the pushing force causes deformation of the third-stage inner catheter 23 to lengthen.
When the needle core device 1 is separated from the distal end of the third-stage internal part catheter 23, the third-stage internal part catheter 23 forms a fungus-shaped expansion part under the action of self deformation force. The specific principle is as follows: since the third-stage inner-part catheter 23 is not under the action of the interference force when the core device 1 is separated from the distal end of the third-stage inner-part catheter 23, the third-stage inner-part catheter 23 is deformed due to the previous interference, and the deformation amount, including the deformation force, is provided, so that the bacterial expansion part is formed under the action of the self deformation force.

In this way, the needle core device 1 is pulled out after being placed into the ureter skin stoma, and a good fixing effect is achieved through the first section of the external part catheter 21 and the third section of the internal part catheter 23.
The second section of skin catheter 22 can be stably fixed in the skin without deformation or displacement, and has good supporting effect on the section of ureter, thereby achieving the purposes of preventing ureter from making a stoma narrow and reducing infection probability.
The catheter device 2 also comprises a first circular ring 3, a second circular ring 4, a third circular ring 5 and a fourth circular ring 6; the first ring 3 and the second ring 4 are used for accommodating and fixing two ends of the first section of external part of the catheter 21, so that the first section of external part maintains a uniform elliptic shape. At the same time, the second ring 4 and the cooperating third ring 5 are arranged at the second skin segment conduit 22 as a deformation demarcation point, thereby preventing deformation of the second skin segment conduit 22. In addition, the third ring 5 and the fourth ring 6 are arranged at two ends of the inner part conduit 23 of the third section, and on one hand, are used as dividing points for deformation, so as to avoid the deformation of the skin part conduit 22 of the second section; on the other hand, the fourth ring 6 can also be used as a control point and directly collides with the needle core device 1, so that the operability is good.
The length of the first section of external part conduit 21 is 0.5cm, and the radial dimension specification is FR8-FR10; the second section of skin portion catheter 22 is 2cm long and has a radial dimension FR6; the length of the third section of internal part conduit 23 is 1-2cm, and the radial dimension of the third section of internal part conduit 23 forming a bacterial expansion part is FR12-FR14.
