Degradable mammary scaffold

Abstract

A degradable mammary scaffold comprises a three-dimensional boundary structure and an inner filling structure; the outline of the three-dimensional boundary structure matches with actual tumor outline of an implant taking patient, the outline of the three-dimensional structure is extended by 1-5 mm along a normal direction based on the actual tumor outline, and the inner filling structure includes a three-dimensional elastic unit array that may intersect with the three-dimensional boundary structure to form the degradable mammary scaffold; after the degradable mammary scaffold is implanted in a human body, mammary form can be repaired, and good overall elasticity and good deforming characteristic to simulate natural mammary tissues are imparted; the unique porous structure of the degradable mammary scaffold helps ingrowth of tissue cells, and mammary implant separation, displacement and other risks are solved; with degrading of the scaffold, autogenous tissues replace the scaffold structure gradually, and finally self-repair is achieved.

Description

technical field [0001] The invention relates to the technical field of tissue engineering and biomanufacturing, in particular to a degradable breast bracket. Background technique [0002] In recent years, the incidence of cancer in my country has been increasing. Breast cancer is the most common cancer among Chinese women. The treatment of breast cancer generally requires mastectomy or mastectomy, combined with later radiation therapy. In addition to being unfavorable for the patient's physical health, mammary gland or mastectomy will directly affect the patient's physical appearance and mental health, and bring inconvenience to daily life. In response to this problem, breast reconstruction surgery can reconstruct breasts for patients, thereby improving the adverse effects of resection surgery. [0003] Depending on the type of implant, breast reconstruction surgery can be divided into autologous tissue transplantation and prosthetic implantation. Among them, autologous ti...

AI Technical Summary

Problems solved by technology

Among them, autologous tissue transplantation has the advantages of no rejection and a strong sense of reality; however, the disadvantages are that there are problems such as autologous tissue absorption and the need for multiple operations

Although prosthesis transplantation can achieve a better breast reconstruction effect, the existing prosthesis materials are mainly silicone gel and other materials, which cannot be degraded after implantation in the human body, and there are risks such as falling off and displacement, which will affect postoperative recovery.
