Background technology
Ureter rack tube is applied very extensive in urological surgery, be applicable in the therapeutic processes such as expansion of the above-mentioned urinary tract operation such as renal calculus, ureteral calculus, " hydronephrosis ", " renal transplantation ", kidney and ureter benign tumor and lithotrite rubble, stricture of ureter, it can play drainage of urine after implanting ureter, prevent the effects such as stricture of ureter and adhesion obstruction.During use, ureter bracket one end is positioned over renal pelvis, and rack body is placed in ureter, and the other end is positioned over bladder.Existing ureter bracket is made by medical macromolecular materials, and for example silicone rubber or polyurethane are made, and tube end each other rightabout bends to circle shape inwardly, and as shown in Figure 1, before and after pipe, end becomes " J " shape, and two " J " pipe is otherwise known as.
Although the application of ureter rack tube has improved success rate of operation, but, after keeping somewhere ureter rack tube, still can cause some complication, common are: reflux, put the rear lumbago of pipe, frequent micturition, urgent micturition, irritation sign of bladder, ureter rack tube calculus etc.Wherein, reflux is a current letter major issue to be solved, has seriously limited the further raising of therapeutic effect.
The reason of reflux is mainly that ureter rack tube is a kind of conduit that can double take-off, in use, vesicoureteral anti-reflux mechanism disappears, when intravesical pressure is greater than renal pelvis and intra-ureteral pressure, will inevitably there is intravesical urine and backflow to ureter and renal pelvis.In addition, put the rear urine of pipe constantly by drain, renal pelvis ureters circular cone has lost full stimulation, causes ureteral peristalsis obviously weaken or disappear, and this also makes urine reflux rate increase.
The consequence of reflux is to cause the chance of kidney retrograde infection to increase, and life-threatening even when serious, has greatly destroyed therapeutic effect.For this problem, there is no at present effective solution, can only be the intravesical urine of indwelling catheter Tube Drain again after inserting ureter rack tube, and the conventional antibiotic that uses; After pulling out catheter, encourage patient to urinate more, make bladder in hollow state; Avoid bladder excessive to fill and prevent that abdominal pressure from increasing; While occurring to infect, apply antibiotic infection control.But these ways can not fundamentally solve this difficult problem of reflux.
Utility model content
The purpose of this utility model is to overcome the above-mentioned deficiency of prior art, and a kind of anti-reflux support tube of ureter is provided, the reflux problem existing fundamentally to solve existing ureter rack tube.After anti-reflux support tube of ureter is correctly kept somewhere in body, urine can only be flowed to drain and enters bladder through single from renal pelvis and ureter by it, and intravesical urine cannot be backflowed to renal pelvis and ureter through it.
For achieving the above object, this utility model provides following technical scheme:
A kind of anti-reflux support tube of ureter, comprise support tube body, described support tube body is divided into renal pelvis section, urine output pipeline section, ureterovesical junction and bladder section from top to bottom in turn, described renal pelvis section, urine output pipeline section are flexible hollow conduit, described ureterovesical junction is draught line, bladder section is fixture block, and one end of described draught line and the afterbody of hollow conduit are fixedly linked, the other end of described draught line be positioned at intravesical fixture block and be connected.
In above-mentioned anti-reflux support tube of ureter, described fixture block elastic for having " C " shape rubber tube.
