23 Jul Glass simulating sponge support and preparing method thereof
Abstract
The invention discloses a glass simulating sponge support and a preparing method thereof, and relates to a medical support and the preparing method thereof. The problem that the structural size of anexisting alloy support cannot be changed according to the size of an affected part and the problem that the applicability of a Ni-Ti shape memory alloy support is limited are solved. A bionic tissue engineering scaffold of the support is a cylinder wall with a through hole, wherein the cylinder wall is composed of an auxiliary support warp and two spirally-surrounding support base yarns, the two support base yarns are bidirectionally surrounding, and ribs are spirally arranged on the outer wall of the bionic tissue engineering scaffold. The peripheral wall of the cylinder structure composed ofthe bionic tissue engineering scaffold and the ribs is a whole, or an opening is formed in the peripheral wall. The bionic tissue engineering scaffold and the ribs are formed through 3D printing witha shape memory polymer as the printing material, and the shape memory polymer is one or more of shape memory polycaprolactone, shape memory polylactic acid and shape memory polyurethane. The glass simulating sponge support is used for designing and manufacturing a medical stent.
