Description
Technical field
The utility model belongs to medical instruments field, in particular to a kind of implant for anal fistula filling.
Background technology
Anal fistula refers to the infectious diseases that anorectal region is communicated with anal skin, it is most of by anorectal abscess ulceration or
It is formed after cutting apocenosis.During abscess healing is reduced, since collar extension skin growth is very fast, into including the intestinal contents of vomica
Accumulate, forms false healing, recurrent exerbation brings pain to patient.
Anal fistula bolt art is that the biomaterial both ends based on strip are separately fixed at interior collar extension to clog the minimally invasive hand in fistula road
There is art painful light, short treating period, the advantage for not damaging anal function and shape, American scholar Lynn to be made of intestinal mucosa
Biological bolt clog the anal fistula caused by craw-craw, cure rate 80%, Wang Zhenjun is in thoroughly processing fistula and on the basis of internal orifice
It takes the lead in introducing biological choke material, also achieves success.Existing anal fistula implant is mostly cone strip on the market, postoperative to be easy
There is the shifting phenomena that falls off, thus cause superinfection, on the other hand, implant surface is smooth to be unfavorable for seeking connections with and being cured for tissue
It closes.
Utility model content
The purpose of the utility model is to overcome above-mentioned deficiencies in the prior art, provide a kind of plant for anal fistula filling
Enter body, is made of cap body and core two parts.Its cap body can fix implantation body position and block fistula mouth, prevent intestinal secretion object from entering
Fistula road causes infection again, and fistula road can be filled in core, and surface folding or groove are set as cell growth and provide network bracket, promote
The healing in fistula road has the characteristics that small resistance, fixing compact, rush are more apparent.
The technical solution of the utility model is as follows：
A kind of implant for anal fistula filling is made of cap body and core.The cap body is in spherical crown shape, the core
In circular cone shape, the core surface is provided with fold or groove.Cap body and the shape of core are respectively facilitated fixed and are filled out
Plug, it is to provide biological support to increase the area that implant is contacted with tissue for tissue that core surface, which has fold or groove,
Promote cell seeking connections in material surface.
Preferably, the basal diameter of a height of 0.5 ~ 3 mm of the cap body, the cap body are 5 ~ 30 mm.To the ruler of cap body
Little progress row limits, and is the size in order to adapt to fistula road junction and prevents the normal physiological activity of implant interference enteron aisle.
Further, the distance at the nearly cap end of the core to remote cap end is 30 ~ 120 mm, and the nearly cap end of the core is straight
Diameter is 5 ~ 15 mm, remote a diameter of 0.2 ~ 4 mm in cap end.The size of core is limited, is to make implant adapt to fistula road
Size.
Preferably, the implant is in the pericardium by corium acellular matrix, intestinal mucosa lower layer or the oxen and horses
What any one was prepared.The material has good histocompatbility and extremely low immunogenicity, can degradation in vivo.
Preferably, the junction of the cap body and the core is arc transition.Arc transition setting is implanted into allow
Body agrees with fistula mouth-shaped, is conducive to fix.
Beneficial effects of the present invention are：
（1）There is core surface fold or groove can increase the area that implant is contacted with tissue, and biology is provided for tissue
Holder promotes cell seeking connections in material surface.
（2）Cap body is in spherical crown shape, can be bonded with fistula road junction closely, reduces the possibility that content is again introduced into fistula road, simultaneously
The excretion of intestinal contents is not influenced.
（3）Any one in the pericardium of corium acellular matrix, intestinal mucosa lower layer or the oxen and horses is all with good
Histocompatbility and extremely low immunogenicity, can degradation in vivo.
（4）Implant is divided into cap body and core, and cap body is conducive to itself fix and intestinal contents isolation, core are conducive to fill out
Plug.

Specific implementation mode
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing, to this reality
It is described in further detail with novel.It should be appreciated that specific embodiments and the drawings described herein are only used to explain this reality
With protection domain that is novel, being not intended to limit the utility model.
The utility model is described in detail with reference to specific embodiment.
Embodiment 1
A kind of implant for anal fistula filling as illustrated in fig. 1 and 2, is made of cap body 1 and 2 two parts of core, described
Cap body 1 be in spherical crown shape, the core 2 be in circular cone shape, 1 surface of the core is provided with fold 5 or groove 6.
The implant is that any one in the pericardium by corium acellular matrix, intestinal mucosa lower layer or the oxen and horses is led to
It crosses and sews, coats or be bonded.The fold 5 or groove 6 on 2 surface of core are to cut, squeeze or integrally formed technique is formed through needle
's.The cap body 1 of implant can block fistula mouth, prevent intestinal secretion object from entering fistula road and cause infection again, and fistula road can be filled in core 2,
Network bracket is provided for cell growth, promotes the healing in fistula road.
The core 2 is nearly cap end 3 close to one end of cap body 1, and the one end of the core 2 far from cap body 1 is remote cap end 4,
The basal diameter of a height of 0.5 ~ 3 mm of the cap body 1, the cap body 1 are 5 ~ 30 mm, and remote cap is arrived at the nearly cap end 3 of the core
The distance at end 4 is 30 ~ 120 mm, 3 a diameter of 5 ~ 15 mm of nearly cap end, 4 a diameter of 0.2 ~ 4 mm of remote cap end.The cap body 1 and institute
The junction for stating core 2 is arc transition.Cap body 1 is bonded closely with fistula road junction, reduces the possibility that content is again introduced into fistula road,
It is to adapt to the shape in fistula road to the dimension limitation of implant.
