Problems solved by technology

[0006] However, similar to the treatment of urinary incontinence, when the vagina is incised and the omentum is placed, there is a possibility that the sling may protrude into the vagina from the wound created by the incision, or complications such as infection from the above-mentioned wound may occur.
In addition, since the vagina is incised, the trauma is large, so there is a disadvantage of placing a large burden on the patient.
In addition, there is a risk of damage to the urethra during the surgery performed by the surgeon, and there is a risk of damage to the fingertips of the surgeon himself.

Abstract

The invention provides a puncture device (1), which is used for surgical treatment of female urinary incontinence. The piercing device is provided with a rotatable piercing member (3). The puncture member (3) has a puncture needle (31) including a needle tip (312), a connecting portion (32), and a shaft portion (33). The piercing device also includes an elongated urethral insertion part (4), and a support part / restriction mechanism (2). The supporting part restricts the positional relationship between the puncturing part and the urethral insertion part, so that when the puncturing part rotates and punctures the living tissue, the needle point passes very below the long axis of the urethral insertion part. The piercing device may also have a vaginal insertion part (5).

Description

technical field [0001] The present invention relates to piercing devices. Background technique [0002] If you suffer from urinary incontinence, especially abdominal pressure urinary incontinence, you will receive abdominal pressure during normal exercise or because of laughing, coughing, sneezing, etc., resulting in urine leakage. The cause thereof includes, for example, relaxation of the pelvic floor muscle, which is a muscle supporting the urethra, due to childbirth or the like. [0003] As far as the treatment of urinary incontinence is concerned, surgical treatment is relatively effective, for example, using a belt-shaped implant called a "sling", which is left in the body and supports the urethra by the sling (for example, refer to Patent Document 1 ). In order to place the sling in the body, the surgeon cuts the vagina with a scalpel, separates the space between the urethra and the vagina, and uses a puncture needle to connect the separated part to the outside throu...
