Abstract
The utility model discloses a kind of double helical form anti-reflux support tube of ureter, comprise urine output pipeline section, be connected to renal pelvis section and bladder section at the two ends of urine output pipeline section, and renal pelvis section and bladder section are backflows to the helicoidal structure of renal pelvis for resisting bladder urine.This utility model utilizes the attribute of helicoidal structure path length, the blocking effect of strengthening to the urine of backflowing to renal pelvis direction from urinary bladder channel support tube, can be dissipated the energy that backflows of urine effectively in long path, thus make helicoidal structure renal pelvis section and bladder section compared to common semicircular structure, effectively slow down urine along the strength of Flows and speed, enhance the effect that antagonism bladder renal pelvis urine stream backflows.This utility model neither affects renal pelvis urine drainage, has again good anti-reflux effect, and structure is simple, is easy to use.
Description
Technical field
This utility model relates to technical field of medical instruments, and it is clinical to be that one is applied to Urology Surgery, has the double helical form anti-reflux support tube of ureter of drainage of urine and anti-reflux dual function.
Background technology
Ureter rack tube is drainage of urine and control stricture of ureter etc., and indwelling is in intra-ureteral conduit, is generally used for the operations such as renal calculus, ureteral calculus, renal transplantation, hydronephrosis, stricture of ureter.Ureter rack tube has the dual function of inner support and drain, effectively can remove upper urinary, and renal function is suffered from protection.Ureter bracket is widely used when treating the disease of urinary system.But current used support tube is double take-off, the situation that in actual clinical, ubiquity urine is backflowed, such as when bladder pressure is increased to a certain degree time, urine can be backflowed renal pelvis outside ureter rack tube tube core and tube wall, thus cause the pathological changes such as upper urinary tract infection and hydronephrosis, infringement renal function.The double J pipe of current domestic and international application makes of polyurethane usually, there is shape memory function, beam end bend becomes elastic ring in its natural state, and respectively in order to be placed in renal pelvis and bladder plays fixation, centre is straight pipe type, omnidistance tube wall is provided with aperture, it is placed in ureteral part, its inner support drainage, that is expands ureter with it, so that by ureteral wriggling, calculus and urine enter bladder along inside and outside pipe.Because ureter rack tube tube core diameter is less, in ureter rack tube inner unidirectional drainage device manufacturing process difficulty, ureter stage casing single-screw shape support tube, owing to aggravating urine bladder renal pelvis reflux on the contrary in the space added around ureter rack tube, also easily affects renal pelvis urine drainage.There is no at present and can be widely used in clinical practicable anti-reflux ureter rack tube, therefore, need a kind of Novel ureteral stent, also can neither affect urine and enter bladder from pelvis drainage, effectively can slow down again urine backflows to renal pelvis from bladder, reduces the risk occurring to infect.
Summary of the invention
This utility model provides a kind of double helical form anti-reflux support tube of ureter, when not affecting its normal drainage, can effectively resist urine and backflowing to renal pelvis from bladder.
This utility model adopts following technical solution:
A kind of double helical form anti-reflux support tube of ureter, comprises urine output pipeline section, be connected to renal pelvis section and bladder section at the two ends of urine output pipeline section, and renal pelvis section and bladder section are backflows to the helicoidal structure of renal pelvis for resisting bladder urine.
Compared with prior art, this utility model has the following advantages:
(1) this utility model utilizes the attribute of helicoidal structure path length, the blocking effect of strengthening to the urine of backflowing to renal pelvis direction from urinary bladder channel support tube, can be dissipated the energy that backflows of urine effectively in long path, thus make helicoidal structure renal pelvis section and bladder section compared to common semicircular structure, effectively slow down urine along the strength of Flows and speed, enhance the effect that antagonism bladder renal pelvis urine stream backflows.
(2) tube wall there is the urine drainage strengthening segment of side opening, further the urine stream of antagonism through backflowing between support tube and ureter tube wall, thus reach and neither affect renal pelvis urine drainage, there is again good anti-reflux effect, and structure is simple, is easy to use, is beneficial to urine drainage.
Accompanying drawing explanation
Figure below is further described this utility model with specific embodiment by reference to the accompanying drawings.
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
A kind of double helical form anti-reflux support tube of ureter, comprise urine output pipeline section 2, renal pelvis section 1 and bladder section 4 is connected at the two ends of urine output pipeline section 2, and, renal pelvis section 1 and bladder section 4 are backflows to the helicoidal structure of renal pelvis for resisting bladder urine, in the present embodiment, between urine output pipeline section 2 and bladder section 4, be serially connected with urine drainage strengthening segment tube wall having side opening 3.
Fig. 1 is structural representation of the present utility model, this support tube implantation mode and common ureter rack tube similar, a seal wire is inserted through cystoscopic operating cavity, be enclosed within outside seal wire by stretching for ureter rack tube, now ureter rack tube renal pelvis section 1 and bladder section 4 are straightened, and send into corresponding site along seal wire, extract seal wire out, support tube resiles, and two ends are hung on renal pelvis and bladder respectively, and renal pelvis section 1 and bladder section 4 recover helicoidal structure.When bladder is in the urine storage phase, renal pelvis urine can enter bladder along the continuous drain of ureter rack tube, when Bladder Voiding Contractions, two double-spiral structures effectively resist the urine of backflowing in the support tube tube core of ureter direction from bladder, proximal ureteral is without side opening, effectively resist the urine of backflowing outside support tube simultaneously, thus reach better anti-reflux object.
Claims (2)
1. a double helical form anti-reflux support tube of ureter, comprise urine output pipeline section (2), it is characterized in that, renal pelvis section (1) and bladder section (4) is connected at the two ends of urine output pipeline section (2), further, renal pelvis section (1) and bladder section (4) are and backflow to the helicoidal structure of renal pelvis for resisting bladder urine.
2. double helical form anti-reflux support tube of ureter according to claim 1, is characterized in that, is serially connected with urine drainage strengthening segment tube wall having side opening (3) between urine output pipeline section (2) and bladder section (4).
