Description

Technical Field

[0001] The utility model relates to the field of medical supplies, in particular to a urological renal pelvis retrograde operation catheter assembly. Background Art

[0002] Patients with chyluria, hydronephrosis or renal cysts need to collect renal pelvic urine, or inject contrast agent into the renal pelvis for contrast examination, or inject drugs such as methylene blue during surgery, which requires a ureteral catheter. Generally, a ureteral catheter is inserted into the urethra on the side of the ureteral catheter for fixation, which is inconvenient to operate, has poor fixation effect, is easy to slip, and the patient's comfort is also poor. Considering the combination of ureteroscopic surgery, a contrast catheter assembly is designed to facilitate the operation. Summary of the invention

[0003] In view of the problems existing in the prior art, the utility model provides a renal pelvic retrograde operation catheter assembly, which is used to place the ureteral catheter into the renal pelvic cavity in conjunction with a ureteroscope. After the ureteroscope is withdrawn, the catheter is inserted along the ureteral catheter. The outer end of the ureteral catheter extends from the outlet branch of the catheter to collect urine or inject contrast agents or drugs to complete examination and treatment. When not in use, the catheter is pulled out and removed, and a leather plug blocks the outlet.

[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0005] The renal pelvis retrograde operation catheter assembly comprises a urinary catheter and a ureteral catheter. The rear end of the urinary catheter is bifurcated to provide an outlet branch that passes through the front port. The ureteral catheter runs through the urinary catheter, and the front end extends out of the urinary catheter to the renal pelvis, and the rear end extends out of the outlet branch. A sealable leather plug is provided at the end of the outlet branch.

[0006] A further improvement is that the outlet branch is located directly below the main tube of the ureteral catheter, so as to facilitate the extension of the outer end of the ureteral catheter.

[0007] A further improvement is that the ureteral catheter is made of silicone or rubber.

[0008] Beneficial effects:

[0009] This component is used in conjunction with a ureteroscope during surgery. The ureteral catheter is placed in the renal pelvic cavity. After the ureteroscope is removed, a urinary catheter is inserted along the ureteral catheter. The outer end of the ureteral catheter extends from the outlet branch of the catheter to collect urine or inject contrast agents or drugs to complete examinations and treatments. When not in use, the catheter is pulled out and removed, and a leather plug blocks the outlet. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] Figure 1 It is a schematic diagram of the structure of the utility model;

[0011] Figure 2It is a schematic diagram of the utility model extending into the renal pelvis when assembled. DETAILED DESCRIPTION

[0012] like Figure 1 As shown, the utility model comprises a urinary catheter 1 and a ureteral catheter 2 made of silicone material. The rear end of the urinary catheter 1 is bifurcated with an outlet branch 3 that penetrates the front end. The ureteral catheter 2 penetrates the urinary catheter 1, and the front end extends out of the urinary catheter 1 to the renal pelvis 5, and the rear end extends out of the outlet branch 3. The end of the outlet branch 3 is provided with a sealable leather plug 4. In order to facilitate the insertion of the urinary catheter, the outlet branch 3 is located directly below the main body of the urinary catheter.

[0013] like Figure 2 As shown, during the operation, the ureteral catheter is placed into the renal pelvic cavity through the ureteroscope. After the ureteroscope is removed, the catheter is inserted along the ureteral catheter. The outer end of the ureteral catheter extends from the outlet branch of the catheter to collect urine or inject contrast agent or drugs to complete the examination and treatment. When not in use, it is pulled out and removed, and the outlet is blocked with a leather plug.

[0014] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
