Development with tissue engineering technique and rise, large quantities of macromolecular materials especially biological adhesive is expected to be answered Use vascular suture technology.Ideal biological binding agent has to meet some clinical requirements:
(1) safe and reliable, avirulence, no three cause (carcinogenic, teratogenesis, mutagenesis);
(2) there is good biocompatibility, itself healing of without prejudice to tissue;
(3) aseptic and can keep aseptic over a period to come;
(4) can use under conditions of having blood and tissue fluid;
(5) quick-binding can be realized under room temperature, normal pressure;
(6) there is good bonding strength and persistency, stick portion has certain elasticity and toughness;
(7) in use to tissue nonirritant;
(8) can gradually degrade after reaching using effect, absorb, metabolism;
(9) there is good use state and be easy to preserve.
Disclosure satisfy that the biological adhesive of above-mentioned all conditions have not been reported.
The existing medical adhesive being commercialized mainly includes fibrin glue, collagen protein bonding agent, alpha-cyano Esters of acrylic acid adhesive, Polyethylene Glycol (PEG) polymer etc., but these materials undoubtedly there is also this some unsatisfactory lacking Point, such as fibrin glue commercial production be difficult problem it is necessary to by strict plasma screening, inactivation of virus, in case The only potential threat of infective virus, and must low temperature storage, using front needing to melt, product adhesion strength low it is impossible to for height Intensity requirement position;Collagen protein bonding agent due to employing thrombin of beef and bovine collagen albumen, increased immunological diseases (as crazy Cattle disease) risk.A-cyanoacrylate class adhesive can be polymerized after meeting water immediately, can make troubles to operation.Glue-line fragility Greatly, it is not suitable with peripheral organs' flexible tissue.And preserve inconvenience, easily occur rotten in wet environment.Burst pressure is little, to some High-tension wound adhesive effect is poor.Catabolite can produce formaldehyde, can cause acute or chronic inflammation, tissue necrosiss and potential Carcinogenecity, therefore cannot be used for in-vivo tissue bonding.Polyethylene glycol hydrogel can serve as tissue adhension.FocalSeal—L (Genyzme Biosurgey, Inc., Britain) is a kind of water miscible bioabsorbable compound.It needs the plenty of time Carry out photoactivation, thus limit it and be applied to adhesive field of stopping blooding.
So far, except this biopolymer having particular/special requirement to material of biological adhesive have trial be used to into Row vascular repair, much by the tissue engineering material of FDA certification because not having suitable method to repair without being applied to blood vessel Multiple.
