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.

Thus, the implant 8 can be buried obliquely.

[0180] In addition, the axis 42 of the urethral insertion part 4 is parallel to the axis of the vaginal insertion part 5, and the axis 333 of the sh...

Abstract

A puncture apparatus includes a puncture needle for puncturing living body tissue, an axial portion, a puncture member including an interlock portion interlocking the puncture needle and the axial portion, an elongated urethral-insertion member insertable into the urethra, an elongated vaginal-insertion member insertable into the vagina; and a supporting member supporting the puncture member, the urethral-insertion member and the vaginal-insertion member. The distal end of the puncture needle includes a sharp needle tip, and the needle is bent in an arc shape centered on the axial portion. The axial portion is freely rotatable on the supporting member, and the supporting member restricts the positional relation between the puncture member and the urethral-insertion member such that when the puncture member rotates and punctures the living body tissue, the needle tip passes a far-position side from the center of the puncture needle compared with the urethral-insertion member or an extended line of such member.

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...
