Background

The ureteral stent tube is a hollow round tube, the tube wall is provided with a plurality of small holes, because the two ends are curled and the middle is straight under the natural state, each end is shaped like letter J and pigtail, also called double J tube or pigtail, the stent tube is placed in the ureter of a human body, the functions of supporting and drainage can be achieved, the ureteral stent tube is a common instrument for urinary surgery, the rapid and accurate placement of the ureteral stent tube is the key of successful operation, the method for placing the stent tube by an endoscope is simple and mature, a guide wire is placed through an operation hole of the endoscope, the stent tube is pulled to be straightly sleeved outside the guide wire, the guide wire is inserted into a renal pelvis through the ureter or is inserted into a bladder through the ureter from the renal pelvis through the bladder, then the guide wire is pulled out to place the stent tube in the body, for laparoscopic or open ureteral operation, the two ends, namely the renal pelvis and the bladder are required to place the stent tube, but the existing double J tube only has openings at the two ends, the guide wire can only guide one end of the stent tube to be placed into the renal pelvis or the bladder, and the other end of the stent tube is in a bent state under the condition of no guide wire guide, so that the placement of the stent tube into the bladder or the renal pelvis is very difficult, especially in laparoscopic surgery, for a beginner of the laparoscopic surgery, the placement of the stent tube under the laparoscope is very difficult, the surgery is long in time consumption, and the wound of a patient is large, so that the improvement is needed.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is overcome prior art's defect, provide a many segmentation folding ureteral stent tube, divide into a plurality of sections with ureteral catheter portion, expose the opening through folding segmentation point department and put into the seal wire to both sides respectively, keep somewhere the stent tube to bladder end and renal pelvis end under the guide wire guide, in peritoneoscope or open ureteral surgery, shorten the time of placing the stent tube greatly.

In order to solve the technical problem, the utility model provides a following technical scheme:

the utility model relates to a folding ureteral stent pipe of many segmentations, including two J pipe main parts, be provided with the side opening on the pipe wall of two J pipe main parts, two J pipe main parts are including the pelvis end elastic ring that communicates in proper order, ureter portion and bladder end elastic ring, be provided with the segmentation point on the pipeline of ureter portion, be provided with elastic connecting line between the pipeline of segmentation point both sides.

As an optimized technical proposal of the utility model, the end parts of the elastic ring at the renal pelvis end and the elastic ring at the bladder end are closed round end heads.

As a preferred technical scheme of the utility model, have two or more on the pipeline of ureter portion segmentation point.

As an optimal technical scheme of the utility model, every segmentation point department the elastic connecting line is total three, and follows the pipeline a week evenly distributed of ureter portion.

Compared with the prior art, the beneficial effects of the utility model are as follows:

the utility model discloses a set up the segmentation point on ureter portion, make two J pipe main parts form sectional foldable structure, the seal wire is put into respectively to both sides to the pipeline opening of the folding department of rethread, keep somewhere the support tube to bladder end and renal pelvis end under the guide wire guide, make among peritoneoscope or open ureter operation, it is simple and easy to put into the operation, and can insert by the double-end, practice thrift operating time greatly, and through a plurality of segmentation point designs, according to ureter operation's position, select suitable segmentation point to fold, therefore, the clothes hanger is strong in practicability, ureter portion pipeline zonulae occludens of segmentation point both sides will be segmented through elastic connecting line, folding back also can the quick recovery, guarantee support and the drainage effect of support tube.
