Description
Technical field
The present invention relates to the technology of medical apparatus and instruments, specifically a kind of implant device repaired for human body soft tissue.
Background technology
Can there is fistula in tissue, cause the reason of fistula and comprise birth defect, wound, tissue infection and Crow grace disease (Chron ' s disease).In many fistulas, anorectal fistula clinical onset rate is high---and in China, its prevalence accounts for 1.67% ~ 3.6% of anal and intestinal disease, and occupy second in the anal and intestinal disease sickness rate of the European and American developed countries such as abroad, its sickness rate is 8% ~ 25%.Anorectal fistula, is also referred to as anal fistula, and the perianal tissue's abscess how to cause because anus body of gland infects, usually cannot spontaneous recovery.Abscess can be passed through operative drainage or naturally flows out, and form passage at place of infected tissue, be called as fistula road, the opening of fistula road on anorectal wall is foramen primum, is commonly referred to as internal orifice, and the opening that fistula road produces in perianal tissue is secondary mouth, is commonly referred to as collar extension.
Anal fistula can be divided into simple anal fistula (single fistula road) and complex anal fistula (Duo Lou road) due to the complexity in its fistula road.In traditional therapy, general simple anal fistula adopts the treatment of drain thread-drawing therapy, and complex anal fistula adopts rectal mucosa lobe to pass art treatment, though clinically there is certain curative effect, but owing to can cause damage to anal sphincter in operation process, cause higher postoperative incontinence risk, relapse rate is higher.
The another kind of technology of Treatment of Anal Fistula is anal fistula bolt technology, and its Therapy characteristics without the risk of postoperative incontinence, but because its structure is only for simple Treatment of Anal Fistula, cannot be applicable to the treatment of complex anal fistula.
Chinese patent application 200680023018.7 and 201110158543.2, discloses a kind of graft adopting plastic material to roll and is used for the treatment of fistula.Plastic material can be the submucous layer of small intestine material of extracellular matrix class, roll the spiral layers cone graft adopting flaky material to wind up, there is multiple limitation in disclosed mechanotherapy anal fistula: one of its deficiency, be configuration of implant be single cone-shaped structure, be not suitable for the treatment of complex anal fistula; Its less than two, that graft adopts flaky material spiral to wind up to form, after implanting, autologous tissue grows into, and to attach face (material wall) vertical for direction and recipient cell, be unfavorable for that the initial stage organizes initial stage liquid infiltration and cell to creep and moves into, cause regeneration and restoration poor effect, treatment cell density heterogeneity; Its less than three, be the upper structure without preventing from deviating from of graft structure design, in Treatment of Anal Fistula, graft has the risk of deviating from.
Chinese patent application 200980119365.3 is improved on basis before, improves to be included in graft end and to add lid-like, for reducing the risk that graft in Treatment of Anal Fistula is deviate from.But do not improve less than one with less than two above described so far.
Chinese patent application 201110350823.3, is disclosed a kind of contour structures of anal fistula bolt, is found by mechanical analysis, although it can reduce the risk come off after apparatus is implanted, is not suitable for the treatment of complex anal fistula.
Summary of the invention
