Abstract
The utility model discloses an ureteral stent, including a pipe body, the body on be equipped with the hole, the one end of body is held for the bladder for renal pelvis end, the other end, body and renal pelvis end between be equipped with the curved pipe, the curved pipe both ends between straight -line distance be 5-10cm, the tangent line and the sharp angle in body place at curved pipe middle part are 115-125. The utility model discloses crooked nature located to the crooked human ureter (UPG) of can following of support pipe, reduces the ureter wall was located to the support pipe to UPG stimulation and friction to reduce patient's discomfort, avoid causing the patient painful.
Description
Technical field
This utility model relates to a kind of ureter rack tube.
Background technology
The ureter bracket used clinically is all straight type usually, and put after pipe crosses renal pelvis and bladder when leading like this, the UPG place that renal pelvis end is connected with ureter, conduit easily leans against on ureter wall, causes patient pain to feel, uncomfortable.Support tube can cause UPG place ureter wall to stimulate and friction, thus it is inadaptable to make patient that patient is produced, and causes patient pain to feel.
Utility model content
For above-mentioned the deficiencies in the prior art part, the problem that this utility model solves is: traditional ureter rack tube is all straight type, and conduit easily leans against on ureter wall, causes patient pain to feel, uncomfortable.
For solving the problem, the technical scheme that this utility model is taked is as follows:
A kind of ureter rack tube, comprise body, described body is provided with hole, and one end of body is renal pelvis end, and the other end is bladder end; Curved pipe is provided with between described body and renal pelvis end; Air line distance between described curved pipe two ends is 5 ~ 10cm, and the angle of the tangent line in the middle part of curved pipe and body place straight line is 115 ° ~ 125 °.
Further, the internal diameter of described body is 1.25 ~ 1.3cm.
The beneficial effects of the utility model
This utility model according to the dissect physiology feature of the renal pelvis of human body and ureter junction (UPG), by the renal pelvis of ureter bracket
Hold in downward 50-100mm length, by human body physiological characteristics, be processed into bending camber, about 120 ° of radians, like this support tube insert renal pelvis fixing after, when getting off along UPG place ureter, the bending meeting of support tube bends nature along human body ureter (UPG) place, reduce support tube to the stimulation of UPG place ureter wall and friction, thus reduce the discomfort of patient, avoid causing patient pain.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of curved pipe in this utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model content is described in further detail.
As illustrated in fig. 1 and 2, a kind of ureter rack tube, comprises body 1, and described body 1 is provided with hole 11, and one end of body 1 is renal pelvis end 2, and other end end is bladder end 3.Curved pipe A is provided with between body 1 and renal pelvis end 2.Air line distance between described curved pipe A two ends is 5 ~ 10cm, and the air line distance between the present embodiment preferred curved pipe A two ends is 9cm.The angle B of the tangent line in the middle part of curved pipe A and body 1 place straight line is 115 ° ~ 125 °, and the present embodiment optimized angle B is 120 °.Further preferably, the internal diameter of described body 1 is 1.25 ~ 1.3cm, and the internal diameter of the preferred body 1 of the present embodiment is 1.27cm.
The foregoing is only preferred embodiment of the present utility model; not in order to limit this utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
Claims (2)
