Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, and particularly relates to a puncture kit for male urinary incontinence. Background Art

[0002] Prostate-related diseases are a type of disease that seriously affects the health and quality of life of men, mainly including benign prostatic hyperplasia, prostate neoplastic diseases, etc. At present, surgical treatment has important clinical value for patients with compensated benign prostatic hyperplasia and clear obstruction, and surgical treatment has extremely high therapeutic significance for prostate neoplastic diseases. However, urinary incontinence after prostate disease seriously affects the quality of life of patients and family harmony, and also increases the burden of medical and health economics.

[0003] The urethral sling operation is a common surgical method for stress urinary incontinence after prostate disease. However, the biggest problem with the traditional urethral sling operation is that the sling cannot be directly placed on the surface of the urethra, so that the sling cannot continuously, accurately and effectively apply compressive force to the urethra, and the compressive force on the urethra is limited, resulting in poor surgical results. At the same time, the incidence of urethral erosion is high, which not only increases the pain of patients, but also greatly reduces the treatment confidence of patients, and also brings new challenges to reoperation.

[0004] In order to improve the success rate of ordinary synthetic material slings and reduce side effects such as urethral erosion caused by such slings, a surgical method of making a composite sling by combining autologous fascia and an ordinary sling is proposed on the basis of the existing technology. This method can avoid rejection reactions caused by exogenous materials and reduce the occurrence of complications such as sling erosion.

[0005] In order to solve the occurrence of urethral erosion under continuous tension of the sling and at the same time have the material advantages of autologous fascia, we innovatively use a fascia pad composite sling to treat male stress urinary incontinence.

[0006] However, there is currently no sling specifically for male stress urinary incontinence on the market, and only the sling for female stress urinary incontinence can be temporarily used as a substitute. However, this sling is very narrow, so that the range of its compressive force is limited, and it cannot uniformly, accurately and continuously apply effective compressive force to the urethra. At the same time, the arc and length of the puncture rod of the sling for female stress urinary incontinence do not conform to the anatomical and physiological structure of the male pelvis, resulting in increased puncture difficulty and increased complication rate, thus greatly affecting the surgical efficacy.
