The present invention relates to a support device for breast prosthesis based on an acellular matrix material of a biological tissue. The support device for breast prosthesis is formed by tailoring a membranaceous material into a petal-shaped planar biological matrix blank and by connecting adjacent edges thereof. The support device can match with the breast prosthesis and provide a support, fixation and coverage for the breast prosthesis in various surgical operations such as mammoplasty and breast orthopedics, to avoid the ptosis and translocation of the breast prosthesis, thereby achieving desirable effects of plastic surgery. Once being implanted, the matrix material of a biological tissue can be integrated into the surrounding breast tissue of the subject, and thus transformed into new tissues in human body without the retention of foreign bodies. The present invention further relates to a method for manufacturing a support device, and a membranaceous biological matrix material.
