Problems solved by technology

[0002] There is a layer of dura mater outside the human brain tissue. Its function is to protect the brain tissue and prevent cerebrospinal fluid from leaking out. If the dura mater is damaged after traumatic brain injury or surgery, artificial dura mater needs to be repaired. There are many artificial dura mater materials available, but their functions Relatively simple, it can only replace the defective dura mater, and has no more functions

Abstract

The invention discloses a multifunctional artificial dura mater. The dura mater comprises a dura mater sheet, the dura mater sheet is prepared from a cytoskeleton layer, a waterproof material layer, anano-silver dressing, a nerve growth factor layer, an anti-adhesion layer, an anti-adhesion drug and a hemostatic drug, wherein the waterproof material layer has a good waterproof effect, the nano-silver dressing has the effects of a strong bactericidal effect, no drug resistance, strong permeability and long antibacterial action time, the nano-silver dressing has the effects of promoting self circulation of tissue around a wound, activating and promoting cell growth and promoting wound healing after being combined with the nerve growth factor layer, the anti-adhesion layer has the effect ofpreventing adhesion to brain tissue, and the hemostatic drug has the effect of hemostasis. According to the dura mater, the multiple structures cooperate with one another, so that the artificial duramater has multiple functions of stopping bleeding, accelerating wound healing and resisting water.
