Abstract
Disclosed is a bending-resistant nerve catheter and a preparation method and application thereof, and relates to the technical field of tissue engineering materials. The catheter of the present application includes an inner layer, a middle layer and an outer layer, and each layer uses raw materials of biodegradable polymers; among them, the inner layer includes a smooth surface inner layer, an oriented microchannel inner layer or a fibrous inner layer, the middle layer is a fibrous middle layer with crossing angles, the middle layer is prepared by entangling micron fibers with a certain angular arrangement, and the outer layer is made of randomly entangled polymer fibers and is tightly bonded to the middle layer.
