Abstract
The invention discloses a ureteral stent, which comprises a tubular body made of medical-grade polymer materials, wherein the ends of the tubular body are inwardly bent in opposite directions to a pigtail shape, and a larger groove (1) and a smaller groove (2) are symmetrically arranged at side walls of the tubular body with H-shaped cross sections. The diameter of the tubular body is 1.4-3.2 and the length thereof is 180-290 mm. The diameters of the larger (1) and the smaller (2) grooves are 0.8-2.0 mm and 0.4-0.8 mm respectively. One of the two pigtail-shaped ends has only the smaller groove (2) side, without the larger groove (1) side. The special open H-shaped structure can prevent blockage due to urine crystals when draining urine, so that the urine can be drained into bladder smoothly.
Description
Technical field
The invention belongs to the surgical operation auxiliary material, especially for the Urology Surgery operation on ureter.
Background technology
Ureter bracket has another name called pigtail pipe or two " J " pipe, be the pipe of Urology Surgery a kind of drainage of urine commonly used, generally be used for the expansion operation process of renal calculus, ureteral calculus, renal transplantation, hydronephrosis, kidney and tumor of ureter operation and stricture of ureter.Also can drainage of urine, prevent stricture of ureter and oncothlipsis ureter etc.Yet existing ureter bracket is owing to be that its aperture is little in the punching of support pipe periphery, and limited amount in the drain process, is easy to form urinary crystal, and peripheral aperture and pipe medium pore are stopped up by crystallization or foreign body, has caused the urine drainage failure.
Summary of the invention
The purpose of this invention is to provide a kind of being difficult for by the ureter bracket of urine crystallization and foreign body obstruction.
For achieving the above object, the tube that the present invention is made by medical macromolecular materials constitutes, and the end of pipe rightabout each other bends to the circle shape inwardly, shape such as pigtail, there is a bigger groove 1 side of pipe, and its relative opposite side has a little groove 2, and its transverse section is for intending the H type.Caliber is 1.4-3.2mm, and length is 180-290mm.Bigger groove 1 diameter is 0.8-2.0mm, and less groove 2 diameters are 0.4-0.8mm.The part that one of them end of pipe bends to the circle shape does not have bigger groove 1 one sides, has only a side of less groove 2.
Adopt said structure, because open plan " H " the type structure of its special whole process, make the obstruction of its pipe that when drainage of urine, can not cause owing to urinary crystal, make urine can arrive bladder smoothly.
Description of drawings

The specific embodiment
The tube that the present invention is made by medical macromolecular materials constitutes, the end of pipe rightabout each other bends to the circle shape inwardly, shape such as pigtail, and there is a bigger groove 1 side of pipe, its relative opposite side has a less groove 2, and its transverse section is for intending " H " type.Caliber is 1.4-3.2mm, and length is 180-290mm.Bigger groove 1 diameter 3 is 0.8-2.0mm, and less groove 2 diameters 4 are 0.4-0.8mm.The part that one of them end of pipe bends to the circle shape does not have bigger groove 1 one sides, has only a side of less groove 2.
