Anti-infection absorbable nursing urethral stent suitable for post-urethral-fissure operation

Abstract

The invention discloses an anti-infection absorbable nursing urethral stent suitable for post-urethral-fissure operation. The anti-infection absorbable nursing urethral stent comprises a tube body, a first balloon, a second balloon, a degradable stent ring, an inner partition tube, a first anti-infection liquid medicine sleeve, a degradable partition body A, a degradable partition body B, a second anti-infection liquid medicine sleeve, a degradable partition body C and a degradable partition body D. Firstly, through the cooperation effect of the first balloon and the second balloon, the bladder can be supported, the urethra can be supported, and the problem of urethral stricture is effectively prevented; secondly, through the degradable stent ring, the problem that in a traditional technology, when the tube body is disassembled, due to the fact that the degradable stent ring is not made of degradable materials, pain is brought to a patient when the degradable stent ring and the tube body are withdrawn together is solved; and finally, through an antibacterial and anti-inflammation structure, dissolution is subjected to an arrangement sequence, thus antibacterial and anti-inflammation liquid medicine can conveniently permeate into the urethra in batches, disinfection in batches is achieved, and meanwhile, the antibacterial and anti-inflammation time is prolonged, and the problem that external germs invade the urethra of the patient in the tube placement process is prevented.

Description

technical field

[0001] The invention relates to the technical field of medical devices, in particular to an anti-infection absorbable nursing urethral support suitable for postoperative hypospadias. Background technique

[0002] Hypospadias is one of the most common congenital urogenital malformations in children, with an incidence rate of about 0.91-1.86%. The main manifestations of the children are abnormal urethral opening, abnormal urine flow, and downward bending of the penis, which leads to the inability of the children to urinate normally and affects the sexual function and fertility of adults. Surgery is an effective method for the treatment of hypospadias, but due to the specific anatomical structure and physiological limitations of the penis, the incidence of postoperative complications is high, such as urine leakage, urethral stricture, urethral diverticulum, and urethral dehiscence. In the early stage of wound recovery after hypospadias surgery (7-10 days after ...
