The present invention relates to a urinary incontinence treatment device using a sling, and more specifically, to reduce the incision site, to reduce the risk of surgery, the operation time is small, the side effects of the tissue around the mesh after surgery A urinary incontinence treatment device using a sling that can be reduced.

In general, urinary incontinence is a symptom of urinary excretion in the bladder through the urethra irrespective of one's intention, that is, involuntary urination that interferes with daily life. Types of urinary incontinence include true incontinence, stress urinary incontinence (tension incontinence), urge incontinence, and first-class incontinence.

Urinary incontinence can be caused by a weak urethral sphincter, when the supportive function of the urethra itself is degraded, or when the closing force is weakened due to injury.The pelvic muscles or ligaments that support the bladder and urethra through repeated pregnancy, childbirth, or surgery When the bladder neck and urethra sag down due to rupture and weakness, when the nerve supporting the sphincter muscle is partially damaged during childbirth and the sphincter muscle is weakened, when the blood vessels in the urethra are contracted after menopause, which greatly weakens urethral resistance, After surgery, such as uterine cancer or rectal cancer, there is a nervous system disease.

Due to the above reason, when the abdominal pressure rises due to laughter, coughing, sneezing, and exercise, the pressure of the bladder is higher than the pressure in the urethra, and urine can suddenly come out through the urethra unconsciously without contraction of the bladder muscle. You can also urinate while walking or sitting.

Urinary incontinence occurs in 30-47% of healthy middle-aged women, causing many women to abandon their social activities or suffer severe depression.

In order to treat such incontinence, a surgical treatment has been proposed to insert a sling (mesh tape) under the urethra to support the urethra. The treatment is disclosed in Korean Utility Model Registration No. 20-332533.

First, the treatment method incise the upper wall of the vaginal opening and both groin of the vaginal opening to a predetermined length, and then insert the needle of the urinary incontinence treatment device into the upper wall opening of the vaginal opening through the inguinal side incision. Then, a sling (mesh tape) is fastened to the tip of the needle and the needle is retracted toward the groin so that the end of the sling (mesh tape) is moved to the incision of the groin.

The urinary incontinence treatment device has three incisions, and there is a problem that it takes a long time and is dangerous because a circular long needle portion penetrates the patient's vagina and muscle tissue.

Meanwhile, when the sling (mesh tape) is inserted into the patient's body, tissue crushing may occur. This occurs because both sides of the sling (mesh tape) are sharp and not smooth.

The present invention has been made to solve the above problems, it is possible to reduce the incision site, reduce the risk of surgery, the operation time is small, can reduce the side effects of the tissue around the mesh after surgery The aim is to provide a urinary incontinence treatment device using slings.

Incontinence treatment device according to a preferred embodiment of the present invention to solve the above problems, the handle; And a needle portion including a rear end portion connected to the handle, a central portion bent by a predetermined angle, and a tip portion having a fixing protrusion for fixing the anchor portion of the sling.

Preferably, the needle portion is formed with a groove line or a projection line along the longitudinal direction.

In addition, the end of the fixing projection is preferably tapered in order to minimize friction with human tissue.

In addition, the handle is preferably formed with a non-slip jaw to prevent slipping.

Preferably, the central portion is bent such that the leading end portion and the trailing edge portion form an angle of 10 degrees or more and 30 degrees or less.

The central portion 42 is bent by a predetermined angle so that the urethra and the tip 43 make about 30 degrees when the needle portion 40 is inserted into the vaginal incision of the patient. For this purpose, the central portion 42 is preferably bent at an angle of about 10 degrees or more and 30 degrees or less.

The tip portion 43 has a fixing protrusion 44 for fixing the anchor portion 140 of the sling 200. Fixing protrusion 44 is inserted into the coupling hole 142 formed in the anchor portion 140 to couple the sling 200 and the needle portion 40. Fixing protrusion 44 is tapered so that the thickness becomes thinner toward the end, in order to minimize damage to the tissue when the needle portion 40 is inserted into the patient's body.

The end of the tip portion 43 is formed pointed. This is for the needle portion 40 to be easily inserted into the patient's body.

Preferably, the needle portion 40 has a groove line 45 formed along the longitudinal direction. The groove line 45 is formed along the longitudinal direction of the needle portion 40 to prevent the needle portion 40 from being bent. On the other hand, as an alternative to the groove line 45, by forming a projection line in the needle portion may be prevented from bending the needle portion.

The handle 20 is a part for gripping the incontinence treatment device 100. Preferably, the handle 20 has a non-slip jaw 22 is formed. The non-slip jaw 22 prevents the surgeon's hand from slipping and allows the surgeon to exert a force toward the front. More preferably, the handle 20 is formed with a projection line 24 to prevent slipping. The handle 20 may be made of ABS resin or the like.

On the other hand, in order to make the handle 20 has a proper weight, it is preferable that an iron core or an iron rod or the like is inserted into the handle 20.

The handle 20 is formed with the letter 'R' (28 in FIG. 5) representing the right and the letter 'L' 26 representing the left. The R 28 and L 26 are described below.

The sling 200 is installed below the urethra by the urinary incontinence treatment device 100 to support the urethra. The sling 200 includes a mesh portion 120 and anchor portions 140 provided at both ends of the mesh portion 120.
