Problems solved by technology

[0003] The current production methods of breast prosthesis have the following defects: 1. The existing prosthesis is obtained according to the affected breast, which is different from the healthy breast, which affects the appearance; 2. The existing silicone prosthesis model only has the significance of improving the appearance and does not have Therapeutic effect; 3. The 3D model corresponding to the prone position (MRI examination position) can only be obtained from the MRI image data alone, which is different from the breast shape in the upright position

Embodiment 1

[0036] The present invention provides a method for making an individualized breast prosthesis based on the MRI image data of the healthy breast, comprising the following steps:

[0037] The first step is to obtain the original 3D laser scanning data of the patient's breast (upright position, end-inspiration) through a 3D laser scanner, and carry out 3D modeling of the healthy breast according to the original 3D laser scanning data. The 3D modeling of the healthy breast includes the entire healthy breast. The lateral mammary glands, the front, outside, and back are the chest and abdomen wall, the side chest wall, and the skin of the back, and the inner side to the midline of the sternum.

[0038] The second step is to obtain the original MRI data of the healthy side breast through MRI (magnetic resonance imaging) scanning (prone position, end inspiratory), and use the midivi cloud platform to import the MRI raw data for three-dimensional modeling. The built model includes the en...

Embodiment 2

[0048] The first step to the third step are the same as in Example 1.

[0049] In the fourth step, first mark the position of the nipple-areolar complex area, and then obtain an individualized three-dimensional model of the breast prosthesis on the affected side that is symmetrical to the three-dimensional model of the healthy breast obtained in the third step according to the mirror image principle.

[0050] The specific operation steps are: import the 3D model of the healthy breast obtained in the third step into 3-matic software, use the mirror image command to obtain an individualized 3D model of the affected breast prosthesis that is symmetrical to the 3D model of the healthy breast, and mark the nipple and areola composite The location of the body area.

[0051] In the fifth step, according to the individualized 3D model of the breast prosthesis on the affected side obtained in the fourth step, use the FDM printer and use polylactic acid (PLA) as the raw material to 3D p...

Abstract

The invention discloses an individualized mammary gland prosthesis manufacturing method based on the normal side mammary gland MRI image data and individualized mammary gland prosthesis thereof. The invention relates to the individualized mammary gland prosthesis manufacturing method based on the normal side mammary gland MRI image data, the data of three-dimensional laser scanning in orthostatismis integrated, and the normal side mammary gland prosthesis is printed in 3D according to the normal side mammary gland image data, so that the appearance of the double-side breast after breast surgery can be more symmetrical, and an individualized three-dimensional prosthesis model with better appearance effect can be obtained. Moreover, a filling material which is more similar to the mammary gland property of the normal side is used in the filling layer, so that the affected side mammary gland has a good symmetrical appearance in the natural state or in the state of wearing the underwear.

Description

technical field [0001] The invention belongs to the technical field of human body implant medical devices, and in particular relates to a manufacturing method of an individualized breast prosthesis based on 3D printing and based on MRI image data of the healthy breast. Background technique [0002] After breast surgery, the existing technology 3D prints the breast prosthesis on the affected side according to the imaging data of the affected breast. For example, Chinese patent application CN 201610277463.1 provides a method for customizing a personalized silicone prosthesis mold based on breast MRI image data, including the following steps: Obtain medical image data in DICOM format output by MRI machine inspection of breasts and surrounding areas of lesions; use 3D modeling software to integrate MRI data of breasts and lesions into CAD 3D digital models; convert CAD 3D digital model files into STL format for 3D printing ; Using laser sintering technology and nylon powder as m...
