Description

A kind of self-tying hernia paster

Technical field

The utility model relates to hernia pasters, and in particular to a kind of self-tying hernia paster belongs to bio-medical material skill Art field.

Background technique

In daily life, tissue and the missing of organ, breakage or functional failure are very common, this is to health of people It constitutes and seriously threatens with life.For a long time, our continuous exploratory development materials and biotechnology, the purpose is to solve to cure Relevant issues in ensure human health, provide service for the prevention, diagnosis, treatment of disease.

Hernia illness, refer to tissue or organ a part have left should position, and pass through human body defect or thin Weak position enter should not position.Hernia illness can cause a variety of diseases, constitute seriously to people's health and life Threat.If hernia illness is not treated, life danger might have at any time, can generally generate that pain, quality are harder, rub and be not easy Also with abdominal pain, abdominal distension, and slowly there is phenomena such as nausea and vomiting, the time can cause a disease area's Intestinal ischemia necrosis so that jeopardizing more long Life.

General adult is with cannot voluntarily rehabilitation after hernia illness, it is necessary to be treated by surgical means.Needle To hernia illness, there is different treatment methods.Wherein traditional treatment method includes: (1) hernia bandage (2) injection closing (3) surgery Operation.But these traditional operations are directly sewed on thick line in breakage, are disadvantageous in that there is tension, wound to hold for suture Easy infection, sharp ache restore slower.

The appearance of hernia paster provides new thinking for treatment hernia illness.In recent years, China researcher mends in hernia Research in terms of piece greatly improves.Such as China Patent Publication No. CN1775188A, publication date is on May 24th, 2006, invention Title are as follows: polypropylene warp-knitted hernia paster and preparation method thereof and China Patent Publication No. CN101518478A, publication date be On September 2nd, 2009, a kind of entitled reticulated for medical hernia paster, above-mentioned file disclose it and are respectively adopted Polypropylene and polycaprolactone are the main material of hernia paster, and all neatly there is cause on made hernia paster periphery, passes through seam during surgery Hernia paster is placed into hernia lesion by conjunction technology, although what is used prepares material difference, product stability, bio-compatible Property, mechanical property is all well and good.

But these hernia pasters all have certain problems: above all of hernia paster is all will by suturing skill It is fixed on hernia lesion, and during movement of patient, muscle stretch caused by movement can make hernia paster tearing suture wound Muscle around mouthful but will deepen the pain of patient if later period patient causes falling off for hernia paster by movement or other reasons Hardship causes further wound；And postoperative wound is easy to produce inflammation, suture difficulty is big, since suture is used after suture Line can be always present on wound, causing to be easy to produce inflammation inside wound；The degradation time of degradable material is not easy to catch up with wound The time that mouth thoroughly heals also is unfavorable for the remodeling of defect tissue, so that ideal effect be not achieved.

Summary of the invention

In view of the above problems, the purpose of this utility model is that in view of the above-mentioned problems existing in the prior art, mentioning For a kind of self-tying hernia paster, solves the trouble that hernia in situ recurs, operation stitching is more, wound is easily pulled, reduce hand Postoperative discomfort, wound inflammation recurrence rate, material degradation opportunity are not easy the technical issues of controlling.

To achieve the goals above, the utility model is realized by following scheme:

A kind of self-tying hernia paster, the hernia paster ontology including knitting forming, the week of the hernia paster ontology Border region is in fiber strip shape, and the width of neighboring area is 2-5cm, and the outer surface of neighboring area is coated with collagen coating, Coating with a thickness of 0.1-1 μm, neighboring area is that polypropylene mesh fabric sanding fiber is superimposed area, and the diameter of fiber is 1-10 μ m.The fiber includes single fiber and bifurcated fiber.

Due to the technical solution more than using, the utility model is used relative to the existing hernia paster through weaving into Sanding technology makes hernia paster neighboring area be covered with superfine fibre bifurcation structure, is coated with collagen in the outer surface of superfine fibre Albumin layer, superfine fibre and collagen can promote cell secretory protein, significantly increase the proliferation of cell, thus in hernia The outer surface of sticking patch forms skin histology, helps hernia paster to be fixed, can promote the healing of wound, prevents movement from tearing It pulls, forms a kind of self-tying hernia paster.Therefore this self-tying hernia paster can have the advantage that reduction suture, fastly Speed is fixed, and reduction scabs, at low cost, easy to use, nontoxic, reduces postoperative pain, and mechanical property is good, reduces wound inflammation The advantages that recurrence rate.This practical design is reasonable, easy to use, can apply to clinic on a large scale.

Detailed description of the invention

Fig. 1 is the structural schematic diagram of the utility model

Specific embodiment

The technical solution of the utility model is described in further detail below in conjunction with attached drawing.

See attached drawing.

The utility model changes on the basis of being the polypropylene hernia paster obtained by China Patent Publication No. CN1775188A Into gained.

A kind of self-tying hernia paster, the hernia paster ontology including knitting forming, the neighboring area of hernia paster ontology 1 2 be in fiber strip shape, neighboring area 2 can using existing polypropylene hernia paster is placed on roughing-up machine, roughing-up machine with The rate of 300r/min-500r/min rotates, and the mode that 2-5cm sanding around hernia paster is handled is processed, so that through polishing The superfine fibre diameter of rear perimeter region is at 0.1 μm -10 μm, and superfine fibre is bifurcation structure, the outer surface of neighboring area 2 at this time Coated with collagen coating, the neighboring area 2 of hernia paster ontology 1 can be placed on collagen protein powder and is dissolved in by the coating of coating 10-20s in solution after water, superfine fibre surface formed coating, coating with a thickness of 0.1-1 μm.

The working principle of the utility model

This self-tying hernia paster can be placed in hernia lesion in the course of surgery, then by every in hernia paster Side seam unifies needle, can fix.

Hernia paster ontology 1 can effectively prevent the pathology of hernia lesion；The neighboring area 2 of hernia paster ontology 1 surpasses Fine fibre increases cellular affinity, can significantly increase the adhesive force of cell, so as to significant inducing cell along ultra-fine fibre The exterior surface area that fast breeding is tieed up in hernia paster forms skin histology, achievees the purpose that suture.

There are following advantages for the utility model:

A. reduce suture: the utility model ties up type hernia paster certainly and can promote the proliferation of cell, in hernia paster appearance Face generates one layer of skin histology, so only needing to close hernia paster under 1 needle is slightly fixed in the every side seam of hernia paster during operation ?.

B. quickly fixed, reduction scabs: the fixation of hernia paster only needs 4 needles, fixed simple, due to being that cell is promoted to increase The package hernia paster of skin caused by growing, so the area that scabs is smaller.

C. at low cost: such as polypropylene hernia paster of raw material used by the utility model, collagen etc. are all cheap easy ?.

D. easy to use: hernia paster obtained by the utility model uses that it is only necessary to suture 4 needles for this hernia Gas sticking patch is fixed on hernia lesion, and operation is simple, and the later period does not need secondary suture etc., simple and convenient.

E. nontoxic: raw material used by the utility model are material existing for nature, and pro-skin is nontoxic.
