Problems solved by technology

[0004] However, if the vaginal wall is incised, there is a possibility that the sling may be exposed to the inside of the vagina from the wound caused by the incision, or that complications such as infection from the wound may occur.
In addition, since the vaginal wall is incised, it is very invasive and places a heavy burden on the patient.
In addition, there is a risk that the surgeon may injure the urethra with the scalpel during the operation, and the surgeon himself may injure the fingertips with the scalpel.

Abstract

This medical tube (30) has a tube-shape main body (31) curved into an arc shape. The main body (31) has a flat cross-sectional shape at the center portion (S4) in the length direction. The cross-sectional shape at the center portion in the length direction of main body (31) is flat and has a minor and a major axis. The angle formed between the short axis (J31) and the plane which includes both the center point of the arc in the central portion (S4) and the center point of the cross-sectional shape with respect to the length direction of the main body is acute. Further, the aforementioned angle is preferably 20°-60°. Such a medical tube (30) is used in treatment of disease in the pelvic organs involving leaving an implant indwelling between the urethral lumen and the vaginal cavity.

Description

technical field [0001] The present invention relates to a medical tube, a medical tube assembly and a set for pelvic cavity treatment. Background technique [0002] If you suffer from urinary incontinence, especially abdominal pressure incontinence, urine leakage occurs when abdominal pressure is applied during normal exercise, laughing, coughing, sneezing, etc. 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] Surgical treatment is effective for the treatment of urinary incontinence. For example, a belt-shaped implant called a "sling" is used to support the urethra by leaving the sling in the body (see, for example, Patent Document 1). To place the sling in the body, the operator cuts the vagina with a scalpel, separates the space between the urethra and the vagina, and connects the separated part with the outside through the obturator using a puncture needle or ...
