3D printing material, neural restoration catheter and preparation method of neural restoration catheter

Abstract

The invention relates to the fields of bioengineering and biomedicine, in particular to a 3D printing material, a neural restoration catheter and a preparation method of the neural restoration catheter. The novel 3D printing material is provided by the invention, substances capable of reducing ultraviolet light transmittance are added into conventional raw materials for biomaterial printing, and thus the 3D printing material can be used for high-precision printing is obtained. Through the material, high-precision biomaterials such as the neural restoration catheter can be prepared by 3D printing equipment.

Description

technical field

[0001] The invention relates to the fields of bioengineering and biomedicine, in particular to 3D printing materials, nerve repair catheters and preparation methods thereof. Background technique

[0002] At present, various traumas such as compression, stretching, tearing, cutting and other reasons cause partial or complete damage to the nervous system, which leads to loss of function and other neurological diseases. For damaged nerves, the neuronal axons of the nerve can regenerate under the right circumstances. With the development of neurosurgery, especially microneurosurgery, the repair and regeneration of nerve injury has become possible. The current research and clinical application of nerve repair techniques mainly include: direct suture, nerve transplantation (autograft or allograft) and repair through nerve-promoting tubes. For long-distance nerve defects, nerve repair catheters are currently a research hotspot due to their wide range of synthetic ...
