The integrally formed three-layer woven simulation artificial blood vessel has a structure similar to that of a blood vessel of a human body, an outer layer, a middle layer and an inner layer are connected with one another through two groups of binding yarns to form a complete pipe wall structure which is similar to the pipe wall structure of an arterial blood vessel of the human body and has high pipe wall elasticity and bulkiness, and the artificial blood vessel is favorable for growing nutrition blood vessels and the like of the human body after being implanted into the human body, is more similar to the three-layer blood vessel wall of the human body compared with the common single-layer or double-layer artificial blood vessel, and can be implanted for a long time.
Description
Technical field
The present invention relates to a kind of one-body molded three layers of woven emulation artificial blood vessel, belong to bio-medical textile fabrics technical field.
Background technology
Blood vessel transplantation is the effective means of treating vascular defects property disease at present.Current, the blood vessel succedaneum that is used for blood vessel transplantation has from blood vessel and other pipeline group from body or allosome to be knitted, and directly or through taking off processing backs such as cell uses; The artificial blood vessel that also has other to utilize woven, knitting or non-organization method to process.Now Weave type artificial blood vessel is in the extensive use of blood vessel transplantation field and obtained good effect.But; Though obtained clinically using widely; Because to take into account mechanical strength, tube wall elasticity simultaneously, tube wall leaks blood and promotes cell tissue function such as grow into when preventing to perform the operation, seek the textile structural that approaches the human vas structure most and seem particularly important.
The human body artery vascular wall mainly is made up of for three layers adventitia, middle film, inner membrance, contains elastic fiber and collagen fiber in the middle film, and elastic fiber has the effect of the blood vessel retraction of the expansion of making, and collagen fiber play keeps tensile effect, has support function.The thickness of film is bigger in general, wherein is distributed with a considerable amount of little blood vessels (below the 1mm), is branched off into blood capillary after these little blood vessels get into adventitia, is distributed to adventitia and middle film.Nutrient vessel has a very important role in vessel growth.If do not have corresponding structure and enough spaces, nutrient vessel just can't be grown into, and growth of artificial blood vessel inner tissue etc. just can not get nutrition supply so, can influence blood vessel in the intravital long-term existence of people.
Conventional monolayers or double-deck artificial blood vessel be not owing to have and the corresponding three-decker of artificial blood vessel; Implant the back and just competent space and nutrition can not be provided for the growth of nutrient vessel; Tunica adventitia and middle film can not get enough nutrition supplies, are unfavorable for long-term existence in vivo; And conventional monolayers or double-deck artificial blood vessel material therefor generally are nondegradable, and long-term its structure of back of implanting might produce inhibition to the growth of human body self tissue, is unfavorable for long-term implantation.
Existing Weave type artificial blood vessel mainly contains following several kinds: the monolayer artificial blood vessel of (1) Weave type; (publication number CN 1565394A and grant number CN20134972Y) is described like Chinese patent; Utilize the variation of basic organization to realize the requirement of artificial blood vessel; But the water permeability of monolayer tube wall etc. need be controlled through the thickness through weft count and yarn of tissue; Tube wall elasticity and water permeability are difficult to reach requirement simultaneously, and the tube wall hole may not reach requirement, and growing into of back cell is implanted in influence; (2) through the weave method of coating collagen protein on the basic artificial blood vessel, fibroin albumen or collagen fibroin blend film of monolayer; Like Chinese patent (grant number 100364620C; Grant number 100364621C and publication number 100364619C), reduce the hole on the tube wall, oozing of blood when avoiding performing the operation; But its tube wall elasticity and thickness are limited, and the uniformity of coating etc. still need be probed into; (3) utilize knitting, woven or itself and the bonded method of additive method obtain double-deck Weave type artificial blood vessel; Like Chinese patent (grant number CN101069756B; Publication number CN101069757B and publication number 101066476A); But double-deck artificial blood vessel structurally still has the structural pipe wall that differs from human vas, is unfavorable for long-term implantation.
Summary of the invention
