Description
Technical field
The present invention relates to a kind of biological glues, and in particular to a kind of injectable biological glue with high-strength adhesion property.
Background technology
The wound suture problem of surgical operation has had been to be concerned by more and more people.Traditional mode generally uses suture
Suture.But suture suture can introduce new suture wound, can cause secondary damage during taking out stitches to wound, and suture holds
Easily cause infection.
So being developed biological glue at present to replace the suture in operation.Biological glue is generally divided into two major classes：
Natural class and synthesis class biological glue.For wherein natural class biological glue using Fibrin Glue as representative, usual intensity is weaker, and
Easy to produce the cross-infection problem of the hematologic diseases such as AIDS.Synthetic glue is with the derivative of cyanoacrylate
Main, intensity is higher, but biocompatibility is bad, and catabolite is toxic.
People's also some new biological glues in Persisting exploitation, such as the bi-component biological glue based on PEG at present
(Coseal and Duraseal), the biological glue based on PEG and chitosan.These biological glues have stronger adhesion property, and
And biocompatibility is good, but these biological glues are usually all bi-component biological glue, when use, must be noted using duplex
Emitter, equipment is bigger, and operation is complex, and the tissue adhesion operation especially for certain profound levels is more difficult.Simultaneously
Most of these glue are mutually crosslinked using chemical action, in use in case of cracking, lead to the irreversible breaking of chemical bond,
These glue can lose its effect, will usually be disposed of and coat new biological glue, be greatly improved the operating time
And cost.
