Description

Integrated tube for nephrostomy

Technical Field

The utility model belongs to the technical field of medical instrument, concretely relates to integrated pipe of nephrostomy.

Background

After percutaneous nephroscopy, a ureteral stent drainage tube and a nephrostomy tube are conventionally reserved, the nephrostomy tube is generally pulled out before a patient is discharged from a hospital, the ureteral stent drainage tube is also called as a double J tube, the ureteral stent drainage tube is generally pulled out about one month after the operation of the patient, and the patient needs to return to the hospital again to pull out the double J tube, so that the pain of the patient is increased, and the medical expense of the burden of the patient is increased. To this problem, the utility model patent of publication No. CN202505943U, the name is integration nephroureteral catheter is provided among the prior art, this integration nephroureteral catheter realizes once only extracting ureteral stent drainage tube and nephrostomy tube through combining ureteral stent drainage tube and nephrostomy tube, but the operation discovery in the operation, hardly define whether nephrostomy tube is installed in place, some patients of long-term nephrostomy tube often meet the fistulation tube head end not in place when changing nephrostomy tube, the drainage is not good need change the problem of processing once more. And part of the small renal pelvis patients are easy to fall off from the renal pelvis after the renal fistulation tube is kept, which is easy to cause poor postoperative drainage and brings great difficulty to the second-stage percutaneous nephroscope operation.

Disclosure of Invention

Detailed Description

The invention will be further described with reference to the embodiments shown in the drawings to which:

example 1

As shown in fig. 1, fig. 2, fig. 3, fig. 4, a nephrostomy integrated tube includes ureteral stent drainage tube 1 and nephrostomy tube 2, ureteral stent drainage tube 1 is single J pipe, the external diameter of ureteral stent drainage tube 1 is less than the internal diameter of nephrostomy tube 2, the one end that ureteral stent drainage tube 1 is not crooked stretches into nephrostomy tube 2 and sets up along nephrostomy tube 2 from the front end of nephrostomy tube 2, the central line of ureteral stent drainage tube 1 and the central line dislocation set of nephrostomy tube 2 and nephrostomy tube 2 front end draw in gradually towards the crooked end of ureteral stent drainage tube 1 and fix on ureteral stent drainage tube 1, nephrostomy tube 2 front end is equipped with an indent cambered surface 3. The cambered surface 3 is provided with a connecting hole 10 communicated with the inside of the nephrostomy tube 2.

The side that kidney fistulization pipe 2 is close to the front end is equipped with side opening 4, the position that is close to the front end on the kidney fistulization pipe 2 still fixedly is equipped with around the gasbag 5 that kidney fistulization pipe 2 set up, side opening 4 is located between 2 front ends of kidney fistulization pipe and the gasbag 5, and the tail end of kidney fistulization pipe 2 is fixed and is equipped with interface 6, is close to tail end position fixed connection pipe 7 that is equipped with and the gasbag 5 intercommunication on the kidney fistulization pipe 2, and the fixed valve 8 that is equipped with of connecting pipe 7 tail end, connecting pipe 7 has part to stretch into in the kidney fistulization pipe 2 and connecting pipe 7 is located the part of kidney fistulization pipe 2 and the inner wall fixed connection of kidney fistulization pipe 2. The ureteral stent drainage tube 1 is provided with a plurality of through holes 9 distributed along the length direction of the ureteral stent drainage tube 1. The length of the part which is gradually furled at the front end of the nephrostomy tube 2 is 1cm, the length of the air bag 5 along the length direction of the nephrostomy tube 2 is 0.5cm, the side hole 4 is a waist-shaped hole, and the length of the side hole 4 is 3mm.

A gap is reserved between one end of the ureteral stent drainage tube 1 extending into the nephrostomy tube 2 and the tail end of the nephrostomy tube 2, and the length of the gap between one end of the ureteral stent drainage tube 1 extending into the nephrostomy tube 2 and the tail end of the nephrostomy tube 2 is 5cm. The part of the ureteral stent drainage tube 1 extending into the renal fistula 2 is fixedly connected with the inner wall of the renal fistula 2.

When the utility model is used, the thin ureteral stent drainage tube 1 is arranged in the ureter of a patient, and the thick kidney fistulization tube 2 is arranged in the renal pelvis to drain the urine in the renal pelvis. When the integrated nephrostomy tube is placed, a guide wire is used for penetrating the nephrostomy tube 2 and the ureteral stent drainage tube 1, because the outer diameters of the ureteral stent drainage tube 1 and the nephrostomy tube 2 are different, the center line of the ureteral stent drainage tube 1 and the center line of the nephrostomy tube 2 are arranged in a staggered mode, and the front end of the nephrostomy tube 2 is gradually drawn and fixed on the ureteral stent drainage tube 1 towards the bending end of the ureteral stent drainage tube 1, so if the connection part of the nephrostomy tube 2 and the ureteral stent drainage tube 1 moves to the connection part of a renal pelvis and a ureter, larger resistance can be generated, a doctor can easily judge that the nephrostomy tube 2 is installed in place through the change of the resistance during operation, the position is exact, the exact drainage purpose is achieved, the channel loss is effectively prevented, and the secondary operation of a patient is facilitated. After operation, the patient can pull out the whole nephrostomy integrated tube once when the patient is discharged from hospital if the calculus is removed completely, so that the patient is prevented from pulling out the double J tube when the patient is discharged from hospital again, and the cost of the patient is saved; if the calculus can not be completely removed, the second-stage percutaneous nephroscope operation is needed, the thinner ureteral stent drainage tube 1 is placed in the ureter to play a role in dilating the ureter, so that a ureter soft endoscope sheath can be conveniently placed in, and the preparation is made for the second-stage soft endoscope operation. The thinner ureteral stent drainage tube 1 is placed in a ureter, so that residual calculi after percutaneous nephrolithotomy can be prevented from falling into the ureter, and the treatment of the second-stage percutaneous nephrolithotomy is facilitated.

For a patient with long-term nephrostomy, the replacement is convenient, the guide wire is arranged from the tail end of the nephrostomy tube 2 of the nephrostomy tube, the front end of the guide wire is arranged in the ureteral stent drainage tube 1 in the ureter, and the nephrostomy integrated tube is withdrawn and replaced by a new nephrostomy integrated tube along the guide wire. Nephrostomy tube 2 has than thick internal diameter, convenient unobstructed drainage, through connecting pipe 7 toward 5 interior water injections 2 milliliters of gasbag, can regard as the internal fixation. In order to facilitate guide of a guide wire, one end of the ureteral stent drainage tube 1, which extends into the nephrostomy tube 2, is close to the tail end of the nephrostomy tube 2, the distance is 5cm, and the connector 6 fixedly arranged at the tail end of the nephrostomy tube 2 can be directly connected to a urine collection bag conveniently. When the integrated nephrostomy tube is replaced, the tail end of the nephrostomy tube 2 is cut off by 5cm, so that the hollow thin tube cavity of the ureteral stent drainage tube 1 can be exposed, a guide wire is conveniently placed, and the integrated nephrostomy tube is convenient to replace in an outpatient clinic.
