Abstract
The utility model is composed of a tubular article made of medical high molecular material, a circle is formed by bending inward the rear ends of the tube towards the mutually opposite directions, just like a pig tail, a larger groove 1 is arranged on the side surface of the tube, a smaller groove 2 is arranged on the other side opposite to the larger groove 1, and the cross section is similar to an H. The tube diameter is 1.4 mm to 3.2 mm, and the length is 180 mm to 290 mm. The diameter of the larger groove 1 is 0.8 mm to 2.0 mm, and the diameter of the smaller groove 2 is 0.4 mm to 0.8 mm. One rear end of the tube, which is bent into a circle, does not have one side of the larger groove 1, and only has one side of the smaller groove 2. Adopting the specific structure which is open during the whole process and is similar to the H, the tube cannot be blocked due to urinary crystallite during the urine draining, and the urine can smoothly reach to the bladder.
Description
Technical field
This utility model 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.
The utility model content
The purpose of this utility model provides 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 this utility model is made by medical macromolecular materials constitutes, 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, 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
Below in conjunction with accompanying drawing to further detailed explanation of this utility model.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a schematic cross-sectional view of the present utility model.
Fig. 3 is one of them terminal schematic cross-sectional view of the present utility model.
The groove diameter that the less groove of 1. bigger grooves 2. 3. is bigger among the figure groove diameter 4. is less
The specific embodiment
The tube that this utility model 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.
