Problems solved by technology

[0004] The above-mentioned related technical solutions have the following defects: after the user extends the needle from the end of the endoscope, due to the flexibility of the hose, it is difficult for the user to control the position of the needle, which in turn makes it difficult for the needle to be positioned precisely at the 6 o'clock position directly below the ureter And inject, so that the bulge formed by the injection of bulking agent is skewed, and the effect on ureteral occlusion is not good

Embodiment 1

[0045] The embodiment of the present application discloses an injection device for treating ureteral reflux. refer to figure 1 , including an injection mechanism 1 and a guide mechanism. The injection mechanism 1 includes a hose 11, a needle 12 and a piston push rod 13. The hose 11 is a flexible hollow structure. One end of the hose 11 is sealingly connected with the needle 12, and the other end is slidingly connected with Piston push rod 13, the user can suck the medical leavening agent into the hose 11 through the piston push rod 13, and inject the medical leavening agent into the patient's ureteral opening 6 o'clock below the bladder mucosa or ureteral wall through the needle 12 Submucosal at the inner 6 o'clock position, that is, the submucosal bladder directly below the ureteral orifice, a crack-like orifice appears after the injection, thereby reducing the chance of urine stored in the bladder entering the patient's ureter and kidney through the ureter, and reducing blad...

Embodiment 2

[0051] The embodiment of the present application discloses an injection device for treating ureteral reflux. refer to Figure 5 , The difference from Embodiment 1 is that the guide 2 is slidably connected to the hose 11 . An installation ring 22 is connected to the guide member 2, and the guide member 2 and the installation ring 22 are connected by integral molding or bonding. The installation ring 22 is sleeved on the hose 11 and can slide along the length direction of the hose 11 . Two convex circles 3 are connected to the hose 11 , the convex circles 3 are annular structures, the convex circles 3 are coaxially sleeved on the hose 11 , and there is a gap between the two convex circles 3 . The convex circles 3 are integrally mounted on the hose 11 , and the mounting ring 22 is located between the two convex circles 3 , so that the guide member 2 can slide back and forth between the two convex circles 3 . The guide piece 2 is slidably connected to the hose 11 through the mo...

Embodiment 3

[0055] The embodiment of the present application provides an injection device for the treatment of ureteral reflux, referring to Image 6 and Figure 7 , On the basis of Embodiment 1, the hose 11 is sheathed with a conduit 4, the conduit 4 is made of a transparent material, the conduit 4 is a circular tube structure, and the conduit 4 is flexible. After the user inserts the endoscope 6 into the patient's body, the catheter 4 can enter the patient's body from the working channel 61 along with the flexible tube 11 . The guide mechanism is set as an elastic end 5, which is connected to an end of the catheter 4 close to the needle 12, and the catheter 4 and the elastic end 5 are connected by integral molding. The user can rotate the catheter 4 in the working channel 61 by rotating the end of the catheter 4 outside the patient. The elastic end 5 has elasticity, and the elastic end 5 can be bent into an arc in a natural state. By using the elastic end 5 instead of the guide 2, the...

Abstract

The invention relates to an injection device for ureter reflux treatment, and relates to the technical field of medical injectors, the injection device comprises an injection mechanism and a guide mechanism, the injection mechanism comprises a hose, a needle and a piston push rod, the needle is connected to one end of the hose, the piston push rod is slidably connected to the other end of the hose, and one end of the guide mechanism is connected to the hose; the guide mechanism is elastic, and in a natural state, the distance between any point on the guide mechanism and the center line of the hose is gradually increased along with extension of the guide mechanism. The device has the effect of improving the accuracy of the injection position of the needle.

Description

technical field [0001] The present application relates to the technical field of medical injectors, in particular to an injection device for treating ureteral reflux. Background technique [0002] Vesicoureteral reflux refers to the pathological state in which urine in the bladder refluxes to the ureters and kidneys, causing a series of adverse effects on the human body. There is a ureter connected between the bladder and the kidney in the human body. One end of the ureter is connected to the kidney and the other end is connected to the bladder. The urine produced by the kidney flows into the bladder through the ureter. Under normal conditions, urine can only flow into the bladder from the ureter in one direction. , the urine in the bladder cannot flow back into the ureters. The pathological state of vesicoureteral reflux can occur when the vesicoureteral junction is abnormal. When the patient has ureteral reflux, one of the treatment methods is that the medical staff pass...
