A kind of pelvic floor patch suspension belt and manufacturing method thereof

Abstract

The invention discloses a pelvic floor mesh suspension band and a manufacturing method thereof. The suspension band is a mesh fabric formed by warp knitting of multiple pieces of longitudinal warp and multiple pieces of transverse weft, the multiple pieces of longitudinal warp are arranged at intervals, the multiple pieces of transverse weft are arranged at intervals, each piece of warp adopts a chain stitch structure that a plurality of coils are formed longitudinally, all the pieces of weft line and are clamped between coils of adjacent warp chain stitches respectively, the adjacent pieces of warp are connected to form a whole, and the pieces of weft on two side edges of the whole form arcs respectively. The warp and the weft are polypropylene monofilaments with diameters in a range of 0.1-0.2 mm. The unit-area gram weight of the suspension band is in a range of 35-40 g / m<2>, the thickness is in a range of 0.4-0.5 mm, and the porosity is in a range of 35-40%. The manufacturing method of the suspension band comprises the steps as follows: knitting, heat setting and laddering. The suspension band is smooth in surface, and edges are free of burrs and obviously thinner than the middle, so that the foreign body sensation after the suspension band is implanted into a human body is greatly reduced, and the manufacturing cost is low.

Description

technical field [0001] The invention relates to a pelvic floor patch suspension belt for implanting into a human body and a manufacturing method thereof, belonging to the technical field of artificial medical fabrics. Background technique [0002] Pelvic floor dysfunction is a common disease that seriously affects the daily life of middle-aged and elderly women, mainly manifested as pelvic organ prolapse, stress urinary incontinence and female sexual dysfunction. According to statistics, there are tens of millions of patients with pelvic floor dysfunction in the world, the incidence rate in my country is 40%, about 50% of women over the age of 50 suffer from pelvic organ prolapse, and 29-35% of adult women suffer from stress Urinary incontinence, the concurrent rate of two symptoms is as high as 63%. The traditional treatment methods are mostly hysterectomy and repair of the anterior and posterior vaginal walls. However, the surgical effect is poor, which can lead to vaginal...

AI Technical Summary

Problems solved by technology

Although the sling with this structure can reduce the burrs on the edge of the sling, the edge of the sling is usually thicker than the middle part, and the edge becomes obviously hard after heat setting, which is also obvious for the foreign body sensation after implanting in the human body. It is more difficult to weave strip-shaped suspenders with narrow width by this method
