The present invention relates to a medical device, and more particularly, to a surgical suture device which is employed in the operation of urinary incontinence surgery and capable of precise and detailed procedures.

A large number of women suffer from urinary incontinence due to physiological characteristics of urine draining through the urethra regardless of their will. The type of urinary incontinence may be classified according to the cause of the onset, but among them, even when the bladder is not contracted, the abdominal pressure (intra-abdominal pressure) rises suddenly when the abdominal pressure (intra-abdominal pressure) increases, Stress incontinence is most common.

Abdominal pressure incontinence as described above is caused by the pressure difference between the bladder and urethra as the bladder neck and urethra stretches toward the vaginal cavity as the tissues supporting the bladder neck and urethra relaxes. In other words, the urinary incontinence symptoms are caused by a decrease in elasticity of tissues around the bladder, rather than a function of the bladder itself.

To treat such abdominal incontinence, muscle training, intravaginal devices, drugs and surgical therapies can be applied. Here, the surgical treatment is generally adopted by the lumbar neck, the urethra or the vaginal wall to the suture, to pull and fix the muscle, ligament or bone side, to return and support the urethra and bladder in place.
