Abstract
The utility model discloses a kind of absorbability surgical sutures comprising suture body and bletilla striata glue-line, the suture body are woven by absorbability silk thread, and the bletilla striata glue-line is coated on outside suture body.The absorbability surgical sutures of the utility model can be degradable in vivo or be fully absorbed by tissue, good biocompatibility, meanwhile, flexibility is good, and suture tubercle fastness is high, and wire body smooth can pass through suture tissue, and sewing effect is good.In addition, the absorbability surgical sutures of the utility model can also reduce patient trauma, promotes wound healing and prevent wound infection.
Description
Technical field
The utility model belongs to field of medical article technology, is related to a kind of absorbability surgical sutures.
Background technique
Surgical sutures refers to that surgeon is used to that the line being stitched together will be organized, and can be used for wound caused by suturing wound
Or the notch in surgical operation, it can be used for ligation blood vessel.Common surgical sutures is biodegradable according to it both at home and abroad at present
Performance is segmented into nonabsorable surgical sutures and absorbability surgical sutures.Nonabsorable surgical sutures does not drop in vivo
Solution, cannot be absorbed by tissue, there is different degrees of tissue reaction, need to take out stitches after suture and for easily leaving scar when suturing epidermis
Trace.Absorbability surgical sutures can be degradable in vivo or be fully absorbed by tissue, and tissue reaction is smaller, is not required to after suture
It takes out stitches, avoids second operation and give patient's bring pain, meanwhile, it can be according to the needs of actual operation, when selecting degradation
Between different suture.Since absorbability surgical sutures has a variety of good performances, obtained in surgical operation
It is widely applied, there is good development prospect.
Absorbability surgical sutures can be divided into single cord and litzendraht wire by structure point.Single cord surface is smooth, with tissue
Frictional force is small, smooth can pass through tissue, have good sewing effect, when suture can reduce patient trauma, but single cord
Flexibility is poor, knots and is easy to slip, it usually needs makes a call to 6~8 knots, increase the time of operation.Litzendraht wire flexibility is good, beats
Knot is not easy to slip, but litzendraht wire is rough, larger with the frictional force of tissue, and there are small chambers for the structure of litzendraht wire
Gap can provide place for the growth and breeding of bacterium, therefore be unsuitable for the wound for infection.
Utility model content
The purpose of this utility model is to provide a kind of absorbability surgical sutures, to solve the above technical problems in extremely
It is one few.
One aspect according to the present utility model, provides a kind of absorbability surgical sutures, including suture body and white
Splendid achnatherum glue-line, suture body are woven by absorbability silk thread, and bletilla striata glue-line is coated on outside suture body.
The suture body of the absorbability surgical sutures of the utility model is woven by multiply absorbability silk thread, can be with
It is degradable in vivo or fully absorbed by tissue, good biocompatibility, meanwhile, flexibility is good, and suture tubercle fastness is high,
Operating time can be reduced.It is coated with bletilla striata glue-line outside suture body, Bletilla glucomannan is extracted from orchid bletilla striata stem tuber
A kind of natural macromolecule amylose arrived, is easily absorbed by tissue, and is coated on outside suture body and forms Bletilla glucomannan coating, can make wire body
Surface is smooth, reduces the frictional force of suture and tissue.Meanwhile Bletilla glucomannan has astringing to arrest bleeding, detumescence and promoting granulation, prevents the medicines such as infection
Reason effect, coats bletilla striata glue-line, it is possible to reduce patient trauma promotes wound healing and prevents wound infection outside suture body.
In some embodiments, absorbability silk thread can be selected from polylactic-co-glycolic acid silk thread, polyglycolic acid silk
Line, poly- dioxa cyclohexanone silk thread, poly- glycol carbonic acid silk thread, collagen fabric silk thread, silk silk thread etc. by human body by that can be dropped
At least one of the silk thread that solution or the material absorbed are spun into.
In some embodiments, polyglycolic acid-calcium stearate coating is also coated with outside bletilla striata glue-line.Poly- hydroxyl second
The coating solution coating that acid-calcium stearate coating is obtained by polyglycolic acid and calcium stearate mixed dissolution is made, in bletilla striata glue-line
Outer coating polyglycolic acid-calcium stearate coating can increase the lubricity of suture surface, reduce the friction of suture and tissue
Power makes suture be easy the tissue by suture, reduces patient trauma.
In some embodiments, chitosan coat is also coated with outside absorbability silk thread.Chitosan has significant suppression
Bacterium effect coats chitosan coat outside absorbability silk thread, and on the one hand can inhibiting the structure of litzendraht wire, there are small lacunas
In bacterium that may be present growth and breeding, on the other hand can prevent wound infection bacterium, promote the healing of wound.
Detailed description of the invention
Fig. 1 is the cross-sectional view of the absorbability surgical sutures of one embodiment of the utility model.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing.
Fig. 1 schematically shows a kind of absorbability surgical sutures of embodiment according to the present utility model.Such as figure
Shown, which includes suture body and bletilla striata glue-line 2, and suture body is compiled by multiply absorbability silk thread 1
It knits, bletilla striata glue-line 2 is coated on outside suture body.
Absorbability silk thread can be with polylactic-co-glycolic acid, polyglycolic acid, poly- dioxa cyclohexanone, poly- glycol carbon
Acid, collagen fabric, silk etc. can be degradable in vivo or the resorbable material that is fully absorbed by tissue in one
Kind or a variety of mixing are as silk thread made of spinning material spinning.In the present embodiment, absorbability silk thread is preferably using around volume
The method knitted is woven, and suture body is formed.
In order to increase the lubricity of suture surface, reduce the frictional force of suture and tissue, the present embodiment is preferably in Bletilla glucomannan
A strata hydroxyacetic acid-calcium stearate coating 3 is coated outside layer 2.
In order to inhibit the growth of bacterium and prevent wound infection, the present embodiment preferably coats shell in absorbability wire surface
Glycan coating 4.
Above-described is only some embodiments of the utility model.For those of ordinary skill in the art,
Without departing from the concept of the present invention, various modifications and improvements can be made, these belong to practical
Novel protection scope.
