Embodiment 1

[0039] Such as figure 1 and figure 2 As shown, the breast filler 1 is a three-dimensional network chest structure composed of many repeated regular hexahedral porous units 11 connected to each other. The porous unit 11 is a regular hexahedron structure that is connected to each other by a plurality of linear edges of the same length. The porous units 11 are connected to each other, so that the host's own tissue can grow into the openings of the interconnected porous units 11. The chest filler 1 The overall porosity is 30%, the thickness of the breast filler 1 is 50 mm, the equivalent spherical diameter of the porous unit 11 is 150 μm, and the equivalent spherical diameter of the connecting part between any two porous units 11 is 500 μm. The porous units 11 are evenly distributed on the chest filler 1 .

[0040] Specifically, the above-mentioned chest filler 1 is made by heat-curing silicone rubber 3D printing method, and the specific steps are as follows: obtain the chest i...

Embodiment 2

[0042] Such as Figure 6 As shown, the breast filler 1 is a three-dimensional network chest structure composed of many repeated helical dodecahedral porous units 11 connected to each other. The porous unit 11 is a dodecahedron structure formed by interconnecting multiple helical ribs with the same length. The spiral rib is a three-dimensional helical structure, and the porous units 11 are interpenetrated and connected with each other, so that the host's own tissue can grow into the openings of the interpenetrated and connected porous units 11. The overall porosity of the chest filler 1 is 30%, and the chest filler The thickness of object 1 is 50 mm, the equivalent spherical diameter of the porous unit is 150 μm, and the equivalent spherical diameter of the connecting part between any two porous units is 500 μm.

[0043] What needs to be explained here is that the porous unit 11 using hexahedron and dodecahedron in the above-mentioned embodiment is only a preferred solution, t...

Embodiment 3

[0045] The difference between embodiment 3 and embodiment 1 is that, as Figure 3 to Figure 5 As shown, the chest filling 1 includes a shell and a solid structure 2. The shell is a three-dimensional network structure composed of many repeated porous units 11 connected to each other. The dodecahedron structure, the solid structure 2 is a 100% solid chest-shaped structure, which can be made of the same material as the shell, the shell covers the upper surface of the solid structure 2, and the entire chest filling 1 is integrally formed. In addition, the above solution is only a preferred solution, and the shell can also be covered on the entire outer peripheral surface of the solid structure 2 or partially cover the outer peripheral surface of the solid structure 2 . The porous units 11 are interconnected so that the host's own tissue can grow into the openings of the interconnected porous units 11 of the chest filler 1. The overall porosity of the chest filler 1 is 20%, and the...

Abstract

The invention discloses chest filler and a manufacturing method thereof. The chest filler is of a three-dimensional mesh-shaped structure formed by mutually communicating a plurality of porous units,and the porous units are communicated with one another in a penetrating mode; the overall porosity of the chest filler is 20-80%, and the chest filler is made of an implantable-level silicone rubber material and is integrally formed by using a 3D printing technology. The chest filler is free of a silica gel material, and the problems of surrounding tissue lesions and the like caused by leakage ofsilica gel contained in breast filler, such as breast prostheses, in the existing market are avoided; the shape and size distribution of the porous units can achieve gradient design and manufacture ofthree-dimensional space distribution, and the hardness and mechanical properties of all the areas of the filler can be conveniently adjusted, so that the chest filler has the softness, hand feeling and mechanical strength similar to those of the traditional prostheses containing the silica gel material; the chest filler can be customized according to personal requirements, and the problem that the existing prostheses are easy to move is reduced.

Description

technical field [0001] The invention relates to a chest filler and a manufacturing method thereof, belonging to the field of medical device manufacturing. Background technique [0002] Patients with breast tumors, breast abnormalities, and pectus excavatum require breast implants to reshape the contours of the breast structure. Especially in recent years, many women choose to place prostheses behind the breast or behind the pectoralis major through surgery to achieve the purpose of breast enlargement. In the prior art, chest fillers such as breast prostheses are composed of an outer silicon rubber elastic chest filler and an inner filler. The internal filling can be made of silicone gel, which has a large molecular weight and is jelly-like, so it feels closer to the normal tissue of the human body. You can also choose to fill the silicone rubber elastic chest filling with physiological saline that is harmless to the human body, but Its feel is relatively poor. [0003] Al...
