Description

Suspension net sheet for treating pelvic floor prolapse

Technical Field

The utility model relates to a surgical operation equipment for treating Pelvic Organ Prolapse (POP), in particular to a suspension net piece implanted in a body for repairing female pelvic floor organ prolapse.

Background

Pelvic floor organ prolapse refers mainly to pelvic organs: pathological reduction of the uterus, vagina and/or adjacent organs of the bladder, uterus, vagina and rectum is caused by pelvic tissue degeneration, trauma, congenital dysplasia or postpartum factors. Pelvic organ prolapse includes vaginal anterior wall bulging, uterine prolapse, vaginal fornix prolapse, vaginal posterior wall bulging, rectal bulging, etc. The surgical approaches include transvaginal, transabdominal, laparoscopic and the like, and various suspension and total pelvic floor reconstruction operations completed by the mesh are safe and minimally invasive treatments for pelvic floor prolapse at present.

With the aging of the social population, POP has become a common disease for middle-aged and elderly women, seriously affecting women's health and quality of life, especially impeding women's work and social activities, known as "social cancer". In economically developed countries, urinary incontinence is more common than hypertension, depression, diabetes and the like, and the medical cost is far higher than that of coronary heart disease, osteoporosis, breast cancer and the like, so that the urinary incontinence is one of the 5 most common chronic diseases threatening the health of women. At present, in the majority of female Pelvic Floor Dysfunction (PFD) patients in China, the diagnosis consciousness is not 1/3, the patients have poor cognition on the disease, or the patients are considered to be inevitable manifestations of the old, or the patients do not have active diagnosis due to shyness and the like, and the diagnosis rate is very low.

Many middle-aged and elderly women often experience lower abdomen discomfort and even dropping and falling of the vulva with lumps with increasing age. These symptoms are in fact the clinical manifestations of pelvic organ prolapse. Statistically, about 75% of women suffer from different degrees of pelvic organ prolapse. How does the pelvic organ prolapse develop? The female pelvic floor can be compared with a hammock composed of muscles, fascia, ligaments and the like, and the tension can be self-adjusted according to environmental changes, so that the hammock is the bladder, uterus, rectum and other organs in the pelvic cavity. With the age increasing, under the influence of factors such as pregnancy, delivery and estrogen level decrease, the supporting function of the hammock is gradually weakened, so that the hammock relaxes and collapses, and the pelvic floor organs such as the bladder, uterus or rectum on the hammock drop. Patients with mild and more than moderate prolapse experience symptoms that affect the quality of life of the patient and require surgical treatment. The degree of prolapse was classified into the degree of prolapse (I to IV) according to POP-Q score. The traditional treatment method of pelvic floor organ prolapse is to excise the prolapsed uterus and the bulging vaginal wall, suture and repair the damaged fascia, or to suspend and fix the bladder. This procedure not only resects the intact uterus, shortens the vaginal length, is traumatic, but the suspended structure remains sutured to the already loose pelvic floor structure, and therefore has a high recurrence rate.

Recently, with the development of surgical mesh materials, various mesh pelvic floor repair systems have come into play, and the treatment of pelvic floor organ prolapse has entered a brand-new minimally invasive mesh implantation era. The mesh pelvic floor reconstruction method has the advantages of no need of abdominal opening, small wound, quick postoperative recovery, difficult recurrence and the like.

Nevertheless, the current surgical mesh material in pelvic floor reconstruction still remains unsatisfactory. As the female ages, the physical function is degraded, and partial fascia and muscles are relaxed, the existing pelvic floor patch on the market is difficult to fix at the relaxed fascia in the operation process, the fixation is not firm, and the conventional operation type fixing point is easy to fall off. Meanwhile, the absorbable pelvic floor patch is fast in degradation speed in clinical use, so that the operation effect is hard to continue.

SUMMERY OF THE UTILITY MODEL

In view of this, in order to overcome the not enough of prior art, the utility model provides a suspension net piece of treatment pelvic floor prolapse, should suspend in midair the net piece easily fixed and fixed firm in the operation, difficult degradation makes the effect of operation continuously firm.

The whole Y-shaped suspension net piece is divided into a front upper net piece, a rear upper net piece and a lower net piece which are integrally connected to form the suspension net piece, and the tail end of the front upper net piece is symmetrically provided with a double-long-arm hanging strip structure.

Furthermore, the suspension mesh is formed by spinning and weaving polypropylene monofilaments and polydioxanone monofilaments with the addition of a nontoxic plasticizer.

Further, the non-toxic plasticizer is phthalate.

Or the suspension mesh is formed by spinning and weaving polydioxanone PDO.

Further, the length of the front upper mesh sheet is 8.0-9.0 cm, the width of the front upper mesh sheet is 1.5-2.5 cm, the length of the rear upper mesh sheet is 8.0-9.0 cm, the width of the rear upper mesh sheet is 1.5-2.5 cm, the length of the lower mesh sheet is 10.0-11.0 cm, the width of the lower mesh sheet is 1.5-2.5 cm, and the length of the double-long-arm sling structure is 10.5 cm, and the width of the double-long-arm sling structure is 0.5-1.0 cm.

Further, the length of the front upper mesh sheet is 8.5 cm, the width of the front upper mesh sheet is 2.0 cm, the length of the rear upper mesh sheet is 8.5 cm, the width of the rear upper mesh sheet is 2.0 cm, the length of the lower mesh sheet is 10.5 cm, the width of the lower mesh sheet is 2.0 cm, and the length of the double-long-arm sling structure is 10.5 cm, and the width of the double-long-arm sling structure is 0.75 cm.

The beneficial effects of the utility model reside in that:

1. the utility model discloses an increase two long arm net piece suspender structures on the front side upper portion net piece of pelvic floor net piece, the long arm net piece passes through the fixed net piece of pubis to solved pelvic floor patch and be difficult to fixed problem in lax manadesma department at the operation in-process.

2. The utility model discloses an adopt the absorbable material preparation of slow degradation to suspend in midair the net piece, utilize the slow specificity of material degradation speed itself, solved effectively that absorbable type pelvic floor patch degrades fast problem in clinical use, make the effect of operation continuously firm.

3. The utility model provides a hang in midair and net the piece and can help clinician according to patient's the condition at the operation in-process, select fixed mode high-efficiently.
