Abstract
The present application relates to a hernia mesh and its preparation method. A preparation method of hernia mesh comprises selecting and adding a first material particle into a filler tube attached to a 3D printer, and making an external pressure pipe connected; heating the filler tube to a first temperature, and maintaining for a first preset time to remove moisture contained in the first material particle; continuously heating the filler tube to a second temperature, and maintaining for a second preset time to completely melt the first material particle; continuously heating filler tube to a third temperature, and using a designed hernia mesh 3D print file to prepare the hernia mesh by the 3D printer. The hernia mesh prepared has controllable pore size, biocompatibility, tensile strength, and elasticity; the preparation process is convenient and quick, reducing the cost; the patient's foreign body sensation and discomfort can be reduced.
