Abstract

The invention discloses a nerve repairing film and a preparation method thereof. The method mainly comprises the steps of treating raw materials, decellularizing, dissolving matrix, drying to form a film, neutralizing and washing and the like. According to the nerve repairing film prepared by the method, active ingredients of the extracellular matrix are maintained, the peripheral nerve suture is directly coated, so that an excellent microenvironment is provided to nerve regeneration, nerves are prevented from adhering to peripheral tissues, and nerve regeneration is promoted.

Description

technical field

[0001] The invention relates to the technical field of medical biomaterials, in particular to a nerve repair membrane and a preparation method thereof. Background technique

[0002] Peripheral nerve injury is one of the common traumas in clinical practice. Studies have shown that after injury, effective measures should be taken to repair the continuity and integrity of the injured nerve, so that the proximal end of the injured nerve can issue regenerated axis buds and reach the distal end to reinnervate. target organ. If the patient is not repaired in time or the repair method is improper, it will cause neuroma or even disability, which will seriously affect the quality of life of the patient. How to improve the effect of nerve repair is still a hot topic.

[0003] At present, the gold standard for repairing peripheral nerve injury in clinical practice is still epineurium suture under the microscope. After simple nerve suture, inflammatory cells invade arou...
