Abstract
The utility model relates to a detachable alimentary canal support, including tubulose unit festival, support head, its characterized in that: tubulose unit festival head and the tail are arranged relatively in proper order, and adjacent two tubulose units collude be connected together with thread between the festival and form support subject, the tubulose unit festival at support subject both ends is through the thread linking bridge head, the both ends off -plate side of tubulose unit festival, support head is equipped with the silicon rubber bag, is equipped with antiphlogistic liquid medicine in the silicon rubber bag, is equipped with the through -hole on the silicon rubber bag, is equipped with the biodegradability membrane on the through -hole. Its beneficial effect does: simple structure, strong adaptability can effectively protect the alimentary canal mucous membrane, can dismantle the decomposition, discharge externally naturally or the scope under take out.
Description
Technical field
This utility model relates to medical instruments field, is specifically related to a kind of dismountable alimentary stent.
Background technology
Present Digestive Tract Stenosis is clinical common disease, place the Main Means that alimentary stent is expectant treatment Digestive Tract Stenosis, gastral support is mainly latticed support, but the support of application is not easily taken out after easily shifting and shifting at present, and digestive tract is produced strong friction and stimulation by the edge of support, therefore the redness that digestive tract is caused by bracket edge, inflammation, pain, even bore a hole, and end support force is bigger, it is also not susceptible to reclaim and takes out, support support force may result in not again stent migration and even falls into gastric, restenosis, it is not easily recycled, time even serious, cause second operation.
Summary of the invention
For overcoming described deficiency, the purpose of this utility model is in that to provide a kind of dismountable alimentary stent, strong adaptability, can effectively protect alimentary canal mucous membrane, it is possible to dismounting is decomposed, and naturally drains and takes out under external or scope.
This utility model solves its technical problem and be the technical scheme is that a kind of dismountable alimentary stent, save including tubular units, bracket head, tubular units joint has certain rigidity and supporting role, described tubular units joint head and the tail are arranged in order relatively, formation rack body is linked together with rope yarn between two adjacent tubular units joints, the tubular units joint at described rack body two ends connects bracket head by rope yarn, described tubular units saves, silicone rubber capsule it is provided with outside the both ends of the surface of bracket head, antiinflammatory medicinal liquid it is provided with in silicone rubber capsule, silicone rubber capsule is provided with through hole, through hole is provided with biological degradability film.
Further, described rope yarn is set to surgical thread.
Further, described rope yarn is set to PLA material.
Further, between described two adjacent tubular units joints, between tubular units joint and bracket head, there is certain intervals.
Further, described tubular units joint is set to rhombus guipure or spherical guipure or singly revolves guipure.
Further, described bracket head is set to cup-shaped or spherical.
This utility model has the advantages that simple in construction, and rack body is connected by rope yarn by tubular units joint, deformable, strong adaptability；Digestive tract is played a protective role by silicone rubber capsule; just in case after stent migration; it can be avoided that digestive tract is produced strong friction and stimulation by the edge of tubular units joint; biological degradability film is under Digestive system effect; can being decomposed, after decomposition, the antiinflammatory medicinal liquid in silicone rubber capsule flows out in through hole; to friction local drug delivery, it is effectively protected alimentary canal mucous membrane and preserves from；Decomposition can be dismantled, naturally drain and take out under external or scope.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is partial enlarged drawing of the present utility model.
In figure: 1 tubular units joint, 2 bracket heads, 3 silicone rubber capsules, 31 through holes, 4 rope yarns.
Detailed description of the invention
Presently in connection with accompanying drawing, this utility model is described in further detail.
nullAccording to Fig. 1、The dismountable alimentary stent of one shown in Fig. 2，1 is saved including tubular units、Bracket head 2，Tubular units joint 1 has certain rigidity and supporting role，Described tubular units joint 1 head and the tail are arranged in order relatively，Formation rack body is linked together with rope yarn 4 between two adjacent tubular units joints 1，The tubular units joint 1 at described rack body two ends connects bracket head 2 by rope yarn 4，Described tubular units joint 1、Silicone rubber capsule 3 it is provided with outside the both ends of the surface of bracket head 2，Antiinflammatory medicinal liquid it is provided with in silicone rubber capsule 3，Silicone rubber capsule 3 is provided with through hole 31，Through hole 31 is provided with biological degradability film，Digestive tract is played a protective role by silicone rubber capsule 3，Just in case after stent migration，It can be avoided that digestive tract is produced strong friction and stimulation by the edge of tubular units joint 1，Biological degradability film is under Digestive system effect，Can be decomposed，After decomposition，Antiinflammatory medicinal liquid in silicone rubber capsule 3 flows out in through hole 31，To friction local drug delivery，It is effectively protected alimentary canal mucous membrane to preserve from.
Further, described rope yarn 4 is set to surgical thread, and after using, under scope, bracket head 2 is conveniently removed with tubular units joint 1, and takes out external.
Further, described rope yarn 4 is set to PLA material, has nontoxic, nonirritant, the feature such as good biocompatibility, hydrolyzable is lactic acid in vivo, and can finally be degraded to carbon dioxide and water, its metabolite is all nontoxic, and can regulate its molecular size range control degradation speed, to reach the degradation time that we need, automatically, after degraded, rack body is disassembled into unit, is automatically drained out external, or under scope, take out external.
Further, between described two adjacent tubular units joints 1, between tubular units joint 1 and bracket head 2, there is certain intervals.
Further, described tubular units joint 1 is set to rhombus guipure or spherical guipure or singly revolves guipure.
Further, described bracket head 2 is set to cup-shaped or spherical.
This utility model is not limited to described embodiment, and anyone should learn the structure change made under enlightenment of the present utility model, and every have same or like technical scheme with this utility model, each falls within protection domain of the present utility model.
Technology that this utility model is not described in detail, shape, structure part are known technology.
