The ureteral dilatation stent comprises two main tubes, wherein the two main tubes are arranged in parallel and fixedly connected; the yarn guide pipes are fixedly installed at the tops of the two main pipes, and the yarn guide pipes are fixedly connected with the two main pipes. The ureteral dilatation stent provided by the utility model has the advantages of better dilatation of a narrow section ureter and good drainage effect.

Description

Ureter dilating support tube

Technical Field

The utility model relates to the technical field of medical treatment, in particular to a ureteral dilatation stent tube.

Background

Ureteral stent tubes are widely used in urological surgery. The ureteral stent tube can drain urine, prevent ureter adhesion and stenosis, and is beneficial to repairing ureteral injury. For patients with ureteral stenosis, a single ureteral stent tube cannot achieve good expansion and drainage effects. For better dilating the narrow ureter, two ureteral stent tubes are clinically placed at the same time. Two guide wires are needed for placing two ureteral stent tubes, so that the medical expense is increased, and the tube placing difficulty is increased. The tails of the two ureteral stent tubes are exposed in urine at the same time, so that the risk of calculus attaching to the tube walls is increased; the friction area between the tails of the two ureteral stent tubes and the bladder mucosa is increased, so that the risks of frequent urination, urgent urination, painful urination and naked-eye hematuria of a patient are greatly increased; two ureteral stent tubes need to be pulled out twice, so that the tube pulling time is prolonged, and the pain of a patient is increased.

Therefore, there is a need to provide a new ureteral dilation stent tube to solve the above technical problems.

SUMMERY OF THE UTILITY MODEL

The utility model solves the technical problem of providing the ureter dilating stent which can better dilate a narrow ureter and has good drainage effect.

In order to solve the above technical problems, the ureteral stent provided by the present invention comprises: the two main pipes are arranged in parallel and fixedly connected; the yarn guide pipe is fixedly installed at the tops of the two main pipes, and the yarn guide pipe is fixedly connected with the two main pipes.

Preferably, the two main pipes are provided with drainage holes.

Preferably, the two main pipes and the guide wire pipe are arranged integrally.

Preferably, both ends of the two main pipes and the wire guide pipe are arranged in a bendable manner.

Preferably, both ends of the two main tubes and the guide wire tube may be curled into a "J" shape.

Preferably, the section surfaces of the two main pipes and the wire guide pipe are arranged in a shape like a Chinese character pin.

Advantageous effects

The utility model provides a ureteral dilation stent, which achieves the purpose of better dilating a narrow ureter by arranging two main tubes in parallel. The two ends of the main tube and the guide wire tube are arranged into the tails which can be coiled into J shapes, so that the main tube and the guide wire tube can be respectively coiled in the renal pelvis and the bladder to prevent the ureteral stent tube from displacing; the integrated, thin and soft tail part is designed to reduce the friction on the mucous membrane of the bladder, thereby relieving the symptoms of frequent micturition, urgent micturition, odynuria and naked eye hematuria of a patient; the wire guide pipe through setting up can make things convenient for placing of whole support pipe.

It should be noted that in the description of the present invention, the terms "upper", "middle", "lower", "lateral", "inner", and the like indicate directions or positional relationships based on those shown in the drawings, which are merely for convenience of description, and do not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

Furthermore, it should be noted that, in the description of the present invention, unless otherwise explicitly specified or limited, the terms "disposed," "mounted," "connected," and "connected" are to be construed broadly and may be, for example, fixedly connected, detachably connected, or integrally connected; may be a mechanical connection; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.

Referring to fig. 1-3, fig. 1 is a schematic view of a ureteral stent according to the present invention, which is placed inside a patient; fig. 2 is a schematic overall structure diagram of a ureteral expansion stent provided by the utility model; fig. 3 is a schematic sectional view illustrating a tubular body portion of the ureteral stent shown in fig. 2, in this embodiment, the ureteral stent is composed of three parts, i.e., two main tubes 1 and a guide wire tube 2, and both ends of the two main tubes 1 and the guide wire tube 2 can be curled into a "J" shaped tail portion for curling in a renal pelvis and a bladder to prevent the ureteral stent from being displaced; the pipe body parts of the two main pipes 1 are connected in parallel, the cross sections of the two main pipes 1 are infinity-shaped, the pipe diameters of the two ends of the two main pipes 1 are thinned, and the drainage holes 3 are formed in the side wall of the pipe body part of the main pipe 1. Through the setting that will be responsible for 1 both ends pipe diameter attenuate, except can making things convenient for putting into of support tube, can also make its afterbody become soft easily to coil.

Compared with the related art, the ureteral dilation stent provided by the utility model has the following beneficial effects:

the utility model provides a ureteral expansion stent, wherein two ends of a main tube 1 and a guide wire tube 2 can be coiled into J shapes, so that the main tube and the guide wire tube can be coiled in a renal pelvis and a bladder to prevent the ureteral stent from displacing. The integrated, thin and soft tail part is designed to reduce the friction on the mucous membrane of the bladder, thereby relieving the symptoms of frequent micturition, urgent micturition, odynuria and naked eye hematuria of a patient; the whole bracket tube can be conveniently placed by arranging the wire guide tube 2; through the setting of drainage hole 3, can improve the drainage efficiency of stand pipe.
