Embodiment

[0035] Hypospadias is a congenital urethral disease. The patient's urethral orifice is not in the prominent position of the glans penis. The urethral orifice can be distributed on the line connecting the normal urethral orifice to the perineum. Most patients may be accompanied by the penis bending to the ventral side.

[0036] Patients with hypospadias are often treated surgically to restore the positive appearance and function of the penis, such as lengthening the urethra to its usual location at the end of the penis. Postoperatively, patients often require insertion of a catheter into the urethra to assist with urethroplasty.

[0037] The urethra 3 stent tube 5 disclosed in the present invention for urethra repair surgery provides many benefits for patients recovering from surgery. For example, the stent tube 5 disclosed in the present invention includes a first balloon 52 , and the first balloon 52 is arranged in the fossa of the prostate gland 2 and is not in contact with ...

Abstract

The invention relates to the technical field of medical instruments, and particularly discloses a urethral stent tube used after a hypospadias repair operation. The urethral stent tube comprises a main body of a tubular shell structure and a first balloon fixed to one side of the outer wall of the main body in a surrounding mode. When a patient needs to place the urethral stent tube, the main body is inserted into the urethra and stops when the first balloon reaches the prostatic fossa position, and then the first balloon is filled so that the first balloon is expanded to clamp the whole stent tube at the prostatic fossa position. Due to the fact that the first balloon does not enter the bladder, the bladder wall is not pressed by the balloons in the catheter indwelling time period, a patient does not feel uncomfortable or even bladder spasm, and the comfort level of the patient is greatly improved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a urethral stent tube used for post-operative hypospadias repair. Background technique [0002] Hypospadias is a common malformation in the urinary system of children. It is reported abroad that the incidence rate can be as high as 1 in 125 to 250 babies born with hypospadias, which shows that the opening of the urethra is not in the common position of the glans penis. The urethral orifice can be distributed on the connection line from the normal urethral orifice to the perineum, and most patients may be accompanied by the curvature of the penis to the ventral side. [0003] Patients with hypospadias are usually treated surgically to restore the normal appearance and function of the penis. When performing hypospadias repair surgery, the operator needs to suture the foreskin coiled tube to form a new tube, and then connect the new tube to the original urethral opening to ...
