Background

The ureteral stent tube is also called as a double J tube and a double pigtail tube, has the functions of stent and internal drainage because two ends are curled and each end is shaped like a pigtail, can relieve temporary obstruction caused by ureter inflammation and edema, prevents wound leakage and ureter stenosis after operation, simultaneously, the integrated system is not directly communicated with the outside, and can avoid bleeding and infection caused by nephrostomy; and because of no restriction and discomfort of the external drainage tube, the patient can get out of bed for activity in early stage, which is beneficial to postoperative rehabilitation; in addition, the ureteral stent can protect and recover renal function and prevent hydronephrosis; has the double functions of internal support and internal drainage, and ensures the smoothness of the ureter reliably. Secondly, the ureteral stent is characterized in that the ureteral stent is made of silica gel and has the model of F5-F8 from small to large; the flexibility is good, and the elasticity is realized; the whole length has many side holes, large inner diameter, thin tube wall and large drainage quantity. The upper part and the lower part of the tube are respectively coiled in the renal pelvis and the bladder, have self-fixing function, are not easy to move up and down, and are easy to place and take out; adaptation of the ureteral stent tube: 1. upper and lower urinary tract operations such as renal calculus, ureteral calculus, hydronephrosis, kidney transplantation, benign tumor of kidney and ureter, etc.; 2. double J tubes are arranged before the extracorporeal shock wave lithotripsy treatment of complicated kidney stones and large kidney stones; 3. treatment or operation of ureteral stenosis, macroureteral disease, etc.; 4. ureteral stent tubes can be placed for stent drainage for ureteral obstruction caused by any reason, such as iatrogenic ureteral injury, acute ureteral obstruction caused by pregnancy, obstruction caused by late-stage tumor pressing ureter and the like;

for a patient with a ureteral stent indwelling in clinic, the stent needs to be pulled out after a certain time, currently, in the process, endoscopic equipment needs to be used in an operating room for pulling out under local anesthesia or general anesthesia, so that the patient does not suffer from secondary operation pain, the cost of the patient is increased, and the medical burden is also increased; therefore, a simple ureteral stent and a pulling device thereof are clinically urgently needed to meet the requirement that the operation can be completed in a ward.

SUMMERY OF THE UTILITY MODEL

The utility model provides a ureteral stent tube kit and a use method thereof, which can relieve the pain of patients and reduce the operation risk.

In order to solve the technical problem, the utility model adopts the following technical scheme: a ureteral stent tube kit comprises a double J tube, a ureter, a push tube, a first guide wire and a second guide wire, wherein the tail part of the double J tube is connected with a first magnet through a traction wire; the end part of the second guide wire is provided with a second magnet, and the second guide wire is provided with length scale marks; the head end of ureter is uncovered for cecum and tail end, the water conservancy diversion mouth has been seted up to preceding tip one side of ureter, the preceding tip periphery of ureter is connected with first gasbag, first gasbag is located the rear of water conservancy diversion mouth, the water conservancy diversion mouth department of ureter is connected with the second gasbag, can shutoff water conservancy diversion mouth after the second gasbag is filled out, be provided with water conservancy diversion passageway and two inflation channel in the ureter, the afterbody of ureter is connected with two gas tubes, two gas tubes communicate with first gasbag and second gasbag through two inflation channel respectively, the water conservancy diversion passageway is connected with the water conservancy diversion mouth.

Adopt above-mentioned technical scheme, the utility model discloses following beneficial effect has: the utility model discloses an in first seal wire puts into renal pelvis with two J pipes, utilize ureter and second seal wire when taking out, outwards pull out two J pipes through magnetic force, it is more convenient simple to use, has avoided the patient to need the operation again when extracting ureter stent tube, has avoided anesthesia and operation risk, has reduced patient's misery, has reduced the cost, has alleviateed doctor's work load.

Detailed Description

As shown in fig. 1-4, the ureteral stent tube kit of the present invention comprises a double J-tube 1, a ureter 2, a push tube, a first guide wire 3 and a second guide wire 4, wherein the tail of the double J-tube 1 is connected to a first magnet 6 through a pull wire 5, the length of the pull wire 5 is 30-50 mm, and the diameter of the first magnet 6 is 1.5-2.5 mm; the end part of the second guide wire 4 is provided with a second magnet 7, and the second guide wire 4 is provided with length scale marks; the head end of ureter 2 is the cecum and the tail end is uncovered, water conservancy diversion mouth 8 has been seted up to preceding tip one side of ureter 2, the preceding tip periphery of ureter 2 is connected with first gasbag 9, first gasbag 9 is located the rear of water conservancy diversion mouth 8, 8 departments of water conservancy diversion mouth of ureter 2 are connected with second gasbag 10, second gasbag 10 fills and to open back can shutoff water conservancy diversion mouth 8, be provided with water conservancy diversion passageway 11 and two inflation channel 12 in the ureter 2, the rear connection of ureter 2 has two gas tubes 13, two gas tubes 13 communicate with first gasbag 9 and second gasbag 10 through two inflation channel 12 respectively, water conservancy diversion passageway 11 is connected with water conservancy diversion mouth 8.

When the utility model is put in, the first guide wire 3 is penetrated into the ureter 2 through the mouth 2 of the ureter with the assistance of the ureter 2 mirror; then the double J tube 1 is sleeved on the first guide wire 3, the head end of the double J tube 1 is inserted into the renal pelvis under the guidance of the push tube and the first guide wire 3, and the push tube can assist the first guide wire and continuously push the double J tube to enter a proper position; then the first guide wire 3 and the push tube are pulled out, the tail end of the double J tube 1 is left in the bladder, and the bent shape of the two ends of the double J tube 1 is convenient for fixing the double J tube per se to prevent displacement;

when the double J-shaped tube 1 needs to be pulled out, the ureter 2 is firstly inserted into a bladder through the urethra, then gas is injected into one of the inflation tubes 13, the gas enters the first air bag 9 through the inflation channel 12, the first air bag 9 is inflated, the ureter 2 is pulled backwards, the first air bag 9 is positioned in the opening of the bladder urethra, and urine in the bladder is drained outwards through the diversion port 8 and the diversion channel 11;

then, 50-100 mL of sterile saline is injected into the bladder through the diversion channel 11, the second guide wire 4 is inserted through the diversion channel 11, the second magnet 7 is arranged at the front end of the second guide wire 4, the second magnet 7 can be attracted with the first magnet 6 connected with the double J tube 1 after being inserted into the bladder, then the second guide wire 4 is pulled backwards, the second guide wire 4 is provided with length scale marks, the first magnet 6 connected with the double J tube 1 enters the diversion channel 11 under the pulling action of the second guide wire 4, then the second air bag 10 is inflated by using the other inflation tube 13, the second air bag 10 can close the inner opening of the diversion channel 11, the first magnet 6 and the second magnet 7 are fixed, and then the ureter 2 is pulled out, so that the double J tube 1 can be pulled out together; it is worth mentioning that the volume of the bladder after emptying urine is only a few milliliters, and the inner cavity is small, so that the two magnets can attract each other when the two magnets are close to each other.

The present embodiment is not intended to limit the shape, material, structure, etc. of the present invention in any form, and all of the technical matters of the present invention belong to the protection scope of the present invention to any simple modification, equivalent change and modification made by the above embodiments.
