Description
Technical Field
The utility model belongs to the technical field of medical equipment, and particularly relates to an expansion balloon capable of being kept in a ureter.
Background
Ureteral stenosis is a common clinical disease, and causes of ureteral deformity include congenital ureteral deformity, such as stenosis at the junction of the renal pelvis and ureter, and secondary ureteral stenosis caused by tumor, trauma, fructification and iatrogenic injury. Traditional treatment modes of ureteral stenosis comprise open surgery, laparoscopic surgery and the like, and are relatively traumatic to patients. Currently, the minimally invasive treatment under ureteroscope becomes mainstream, and the treatment modes comprise a ureteroscope dilatation balloon (such as CN201810988097.X), ureterotomy and the like. The prior ureteral dilatation balloon is disposable and cannot be kept in the body when being used in an operation, otherwise complications such as hydronephrosis, renal failure and the like can be caused. After ureteroscope treatment, double J tubes or ureteral stents can be left, but the double J tubes have no continuous expansion function, and the narrow section is easy to retract; although the ureteral stent can be kept in place for a long time, the ureteral stent has the defects of high cost, need of regular replacement, need of secondary operation during replacement and the like.
The problems of the existing ureteroscope lower dilatation balloon are as follows:
(1) the ureteroscope is placed during ureteroscope operation, the operation is performed for a short time, and the stricture ring is possibly retracted after expansion;
(2) the gas is required to be injected into the gas by matching with a pressure pump, so that the cost is higher;
(3) the urine drainage function is absent, and the body can not be kept in place, otherwise hydronephrosis and even renal failure can be caused. The existing ureteral stent (double J tube) has the following problems:
(1) the expansion function is not provided, the urine drainage function is only realized, and the retraction of the narrow ring cannot be avoided;
(2) needs secondary operation and removal, and increases the operation cost and the economic cost of patients.
The problems of the existing ureteral stent are as follows:
(1) the stent indwelling body can cause secondary injury, and new stenosis appears outside the stenosis section;
(2) the bracket needs to be taken out in a secondary operation, so that the operation cost and the economic cost of a patient are increased;
(3) the cost is high, and the wide popularization is difficult.
Based on the defects in the prior art, the utility model provides an expansion balloon capable of being kept in a ureter, can provide a device capable of continuously expanding after ureter stenosis operation, and has the characteristics of convenience in operation, small wound, low cost and the like.
Disclosure of Invention
The utility model aims to provide an expansion balloon capable of being kept in a ureter, which is used for being placed in an original ureter narrow part through a ureteroscope operation channel after an operation, expanding and draining urine, can be kept for a long time, avoids the contraction of the expanded ureter narrow part and reduces the recurrence rate of ureter narrow part.
The utility model provides an expansion sacculus capable of being kept in a ureter, which consists of a sacculus 1, a hose 2, a clamping device 3 for transfusion and a three-way joint 4, wherein one end of the sacculus 1 is connected with one end of the hose 2, the other end of the hose 2 is connected with one interface of the three-way joint 4, the clamping device 3 for transfusion is sleeved at the position, close to the three-way joint 4, of the hose 2, and the other two interfaces of the three-way joint 4 are respectively used for connecting a pressure measuring sensor 5 and an inflation or liquid filling joint 6.
In the utility model, the saccule 1 is made of silica gel or plastic.
In the utility model, the balloon 1 is an expandable balloon and is used for inflating or filling liquid, the volume of the balloon is 1-50ml, the major diameter is 0.1-5cm, the diameter of the inflated or balloon can reach at least 0.5cm after inflation, and the continuous expansion of the narrow section of the ureter is maintained.
In the utility model, a plurality of side hole outflow tracts (7) are arranged in the balloon 1, and the diameter of each side hole outflow tract is 1-2mm, so that the side hole outflow tracts can be used for draining urine or allowing a double J-shaped tube to pass through.
In the utility model, the hose 2 is made of silica gel or plastic, has a length range of 5-100cm and a diameter of less than 0.5cm, and can be used for operating a duct through a ureteroscope.
The utility model is placed into the narrow part of the original ureter through the ureteroscope operation channel after the operation, and is fixed in the lumen through the expansion balloon, and the side surface of the balloon is provided with an outflow channel, so that the urine can be allowed to flow out while the ureter is maintained to be expanded. The other end of the sacculus is connected with a hose which can be placed outside the body through the bladder and the urethra and is connected with an injector, a pressure measuring device and the like through a three-way joint. The injector injects gas or liquid to expand the saccule, then the pressure can be measured, when the set pressure is reached, the hose can be clamped by the clamping device, and the pressure in the saccule can be maintained. When the indwelling saccule is taken out, the clamping device is opened, and the air or liquid in the saccule is pumped out through the injector, so that the saccule can be pulled out of the body.
The utility model has the advantages that:
(1) different from ureter expansion sacculus, the ureter expansion balloon can continuously maintain the ureter expansion state after ureteroscope operation treatment of ureter stenosis, and prevents the retraction of a stenosis ring;
(2) the indwelling saccule is led out of the body through the hose, so that the operation is convenient;
(3) the outflow tract on the side surface of the balloon can play a role in draining urine, so that the occurrence of postoperative hydronephrosis is prevented.
The utility model has the beneficial effects that:
(1) the cost for maintaining the ureter expansion state after the ureter stenosis operation is reduced, the success rate of the operation is improved, the incidence rate of the secondary operation is reduced, and the social and economic burden of the patient is reduced;
(2) the complication incidence rate after ureter stenosis operation is reduced, and the trauma of the operation to a patient is reduced;
