Abstract
The utility model discloses an anti-backflow ureter bracket tube which comprises a pelvis section, a ureter section and a bladder section in successive communication, wherein an anti-backflow baffle is arranged on the exterior of a tube wall at a joint of the ureter section and the bladder section. When urine is drained from the pelvis to the bladder, the urine excretion is not influenced by the anti-backflow ureter bracket tube; when the bladder starts to contract during an urination process, a bladder opening of the ureter is covered by the anti-backflow baffle under the driving of the urine flowing to the pelvis along the periphery of the ureter bracket tube, so that the backflow urine on the periphery of the tube wall of the ureter bracket tube is effectively reduced, the drainage is not influenced and an anti-backflow effect is good; the structure is simple and the application is easy.
Description
Technical field
This utility model belongs to clinical medicine surgery technical field, is a kind of anti-reflux support tube of ureter.
Background technology
Ureter rack tube is to be drainage of urine and control stricture of ureter etc., and keeps somewhere in intra-ureteral conduit, is generally used for the operations such as renal calculus, ureteral calculus, renal transplantation, hydronephrosis, stricture of ureter.Clinical practice proves, double J pipe has the dual function of inner support and drain, can effectively remove urinary tract obstruction, and renal function is suffered from protection.Ureter bracket is widely used when the disease for the treatment of urinary system.Yet current used support tube is double take-off, the situation that in actual clinical, ubiquity urine is backflowed, when being increased to a certain degree when bladder pressure, urine can be along ureter rack tube tube core and the tube wall renal pelvis that backflows outward, thereby cause the pathological changes such as upper urinary tract infection and hydronephrosis, infringement renal function.Because ureter rack tube tube core diameter is less, in the inner unidirectional drainage device of ureter rack tube manufacturing process difficulty, and easily affect renal pelvis urine drainage.There is no at present and can be widely used in clinical practicable anti-reflux support tube of ureter, therefore, need a kind of novel ureter rack tube, neither affect urine and guide bladder into from renal pelvis, can effectively slow down again urine and backflow to renal pelvis from bladder, reduce the risk that infection occurs.
Utility model content
Technical problem: this utility model provides a kind of and does the used time not affecting its normal urine drainage, can effectively slow down urine and backflow to the anti-reflux support tube of ureter of renal pelvis from bladder.
Technical scheme: anti-reflux support tube of ureter of the present utility model, comprise the renal pelvis section, urine output pipeline section and the bladder section that are communicated with successively, the body of urine output pipeline section and bladder section junction is outside equipped with anti-reflux catch, anti-reflux catch is umbrella shaped support structure, center is fixedly connected with support tube tube wall, and anti-reflux catch comprises the activity ring plate and the connecting portion that is positioned at activity ring plate center and is fixedly connected with support tube tube wall that forms umbrella shaped support main body.
In this utility model, part that anti-reflux catch is fixedly connected with support tube tube wall adopts elastomeric material, anti-reflux catch can be around it fixing point on support tube tube wall, to the urine direction contractile motion that backflows.
In this utility model, the section of anti-reflux catch is arch, and the inner side of arch is towards urine output pipeline section one side.
Beneficial effect: this utility model compared with prior art, the advantage having the following advantages:
Anti-reflux support tube of ureter of the present utility model is by arranging anti-reflux catch at body Ureterovesical junction, in urine, from renal pelvis, do not affect urine excretion during to bladder drainage, when the phase bladder of urinating starts to shrink, owing to promoting anti-reflux catch to the mobile urine stream of renal pelvis direction around along ureter rack tube, cover tubal bladder opening, effectively slow down the urine of backflowing along ureter bracket tube wall around, neither affect drain, there is again good anti-reflux effect, and simple in structure, be easy to use.In this utility model, the part that anti-reflux catch is fixedly connected with support tube tube wall adopts elastomeric material, the section of anti-reflux catch is arch, and the inner side of arch is towards urine output pipeline section one side, and assurance activity ring plate covers tubal bladder opening when urine is backflowed.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is this utility model anti-reflux catch partial schematic diagram;
Fig. 3 is bladder anti-reflux catch schematic diagram while starting to shrink.
In figure, have: renal pelvis section 1, urine output pipeline section 2, bladder section 3, anti-reflux catch 4, connecting portion 41, activity ring plate 42.
The specific embodiment
Figure below is further described this utility model with specific embodiment by reference to the accompanying drawings.
As shown in Figure 3: the anti-reflux support tube of ureter of the present embodiment, the connecting portion of its urine output pipeline section 2 and bladder section 3 arranges the anti-reflux catch 4 of umbrella shaped support structure outward, forms anti-reflux structure.Anti-reflux catch 4 comprises the activity ring plate 42 and the connecting portion 41 that is positioned at activity ring plate 42 centers and is fixedly connected with support tube tube wall that forms umbrella shaped support main body.Connecting portion 41 materials are soft but have and have elasticity, and activity ring plate 42 is with respect to connecting portion 41 bendings when without External Force Acting, and section is arch, and the inner side of arch (bottom) is towards Ureteral orifice.
While using anti-reflux support tube of ureter of the present utility model, first seal wire is inserted to ureter and renal pelvis through Ureteral orifice, now this ureter rack tube is pushed along seal wire, renal pelvis section 1 is positioned at renal pelvis, urine output pipeline section 2 is positioned at ureter, bladder section 3 is positioned at intravesical, and anti-reflux catch 4 next-door neighbour's tubal bladder openings, extract seal wire.When urine is from renal pelvis during to bladder drainage, anti-reflux catch 4 is held open state under the elastic reaction of himself, and activity ring plate 42 is with respect to connecting portion 41 bendings, be the umbrella-shaped structure opening, the section of activity ring plate 42 is arch, and the medial surface of arch, to Ureteral orifice, does not affect urine drainage.When the phase bladder of urinating starts to shrink, as shown in Figure 3, owing to around promoting to the mobile urine stream of renal pelvis direction along ureter rack tube, the backflow direction of activity ring plate 42 along bladder to renal pelvis moved with respect to connecting portion 41, cover Ureteral orifice, effectively slow down the urine of around backflowing along ureter bracket tube wall, thereby effectively resist urine, backflow and enter renal pelvis.
This device manufacturing process is simple, easy to use, can significantly resist VUR, does not affect renal pelvis urine drainage simultaneously.
