3D printing-based capsule contracture-preventive breast prosthesis manufacturing method and breast prosthesis

Abstract

The invention discloses a 3D printing-based capsule contracture-preventive breast prosthesis manufacturing method and a breast prosthesis, and aims at solving the technical problem that the capsule contracture is formed after the breast prosthesis is implanted. The manufacturing method comprises the following steps: receiving the acquired medical image data of a breast; establishing a 3D capsule contracture-preventive breast prosthesis model based on the medical image data of the breast, wherein the capsule contracture-preventive breast prosthesis consists of a bag wall layer and a filled layer from inside to outside; the bag wall layer consists of a bag wall inner layer, a bag wall drug-carrying layer and a bag wall rough surface texture outer layer from inside to outside; and performing 3D printing onthe capsule contracture-preventive breast prosthesis based on the 3D capsule contracture-preventive breast prosthesis model. The rough surface texture structure of the bag wall rough surface texture outer layer can break through the continuity of the fibrous capsule so as to reduce the forming of the fibrous capsule, and the capsule contracture-preventive drug loaded on the bag ball drug-carrying layer is slow-released on the bag wall rough surface texture outer layer and can prevent the excessive proliferation of the surface fiber cells; and the breast prosthesis is manufactured by combining the 3D printing, so that the occurrence rate of the capsule contracture can be reduced.

Description

technical field [0001] The invention belongs to the technical field of human implantable medical devices, and in particular relates to a method for making an anti-capsular contracture breast colloid based on 3D printing, and an anti-capsular contracture breast prosthesis made by using the method. Background technique [0002] The progress of comprehensive treatment methods for breast cancer has improved the survival rate of postoperative patients, and the continuous improvement after surgery has provided more favorable conditions for breast reconstruction after breast cancer surgery. [0003] Since the development of sub-breast reconstruction technology, prosthetic implant reconstruction technology has developed the earliest and is relatively mature, and has the most extensive clinical application. The ideal filling material for breast implants should have the characteristics of no interference from soft tissue, no chemical activity, no inflammatory reaction, no carcinogenic...
