The invention discloses a composite amnion for improving contracture after tissue repair and a preparation method of the composite amnion. The composite membrane comprises a recombinant humanized collagen nanofiber membrane located in the middle layer and human decellularized amniotic membranes attached to the two faces of the nanofiber membrane. The composite membrane is prepared by preparing a recombinant humanized collagen nanofiber membrane through an electrostatic spinning technology and pressing the recombinant humanized collagen nanofiber membrane and a human decellularized amniotic membrane. The composite membrane has excellent mechanical properties and biological activity. Animal experiment results show that the composite film can effectively inhibit capsule contracture induced by radiotherapy, and the comprehensive effect of the composite film is obviously superior to that of a single-component material in the aspects of inflammation resistance, fibrosis resistance, degradation speed delaying, capsule compliance improving and the like. The composition can be used for improving the capsule contracture of the breast prosthesis, especially the capsule contracture induced by radiotherapy.

Disclosed are a tissue expander for breast reconstruction comprising an MMP sensor and thus being capable of real-time capsular contracture monitoring and treatment, and a patient information system linked thereto. According to these, a patient or medical staff can easily check and evaluate capsular contracture, which may occur when wearing a tissue expander for breast reconstruction, and whether inflammation, a side effect, or the like is caused thereby, even outside the human body in real time. Accordingly, before or when capsular contracture occurs, effective treatment and response are possible.

The invention provides a degradable breast patch used for covering an implant prosthesis, the surface of the implant prosthesis comprises a first area used for being away from pectoral muscles and a second area used for being positioned to the pectoral muscles, the breast patch is used for at least covering the first area, the part used for covering the first area is a first forming patch, and the part used for covering the second area is a second forming patch. The overall contour of the support is of a curved surface structure and comprises an inner surface contour surface and an outer surface contour surface, the internal structure of the support comprises a support body with a plurality of meshes, and any mesh is communicated with other meshes in the X-axis, Y-axis and Z-axis directions of the mesh; a plurality of submicron fibers penetrate through any mesh, and any submicron fiber extends from the outer surface contour surface to the central axis of the inner surface contour surface. Through the synergistic effect of the three-dimensional space pore structure and the penetrating mesh oriented submicron fibers, a regeneration tissue layer matched with the biomechanical property of a natural breast fat layer is finally formed on the surface of the prosthesis, and therefore continuous inhibition of capsule contracture and long-term stable fixation of the prosthesis are achieved.

Methods and products for treating capsular contractures of breast implants including (1) obtaining a platelet-rich plasma (PRP) or platelet-rich fibrin (PRF) fraction from a patient who exhibits capsular contracture of a breast implant; and (2) applying the PRP or PRF fraction to said capsular contracture, thereby relaxing the capsular contracture.

The present invention relates to a breast reconstruction tissue expander capable of real-time monitoring and treatment of capsular contracture including an MMP sensor, and a patient information system associated therewith. According to the present invention, patients or medical staff can easily check and evaluate in real-time, even from outside the human body, the presence of capsular contracture that may occur when wearing the breast reconstruction tissue expander, as well as the resulting inflammation or side effects. Consequently, effective treatment and response become possible before or when capsular contracture occurs.

Disclosed is a degradable breast prosthesis shaping mesh (10) having a heterogeneous hierarchical porous structure, comprising a macroporous structure layer (100) and a microporous structure layer (200). The macroporous structure layer (100) and the microporous structure layer (200) are formed by alternately arranging and combining degradable fibers to conform to a breast prosthesis, thereby providing the mechanical properties and tissue adhesion properties required by the mesh (10). The macroporous structure layer and the microporous structure layer cooperate to achieve the function of integrating the prosthesis with the tissue, without the need for an additional suturing fixation device. The overall shape of the mesh (10) is designed as a hemispherical upper cover (11) and a lower end cover rim (12), thereby simplifying the assembly process with the prosthesis and improving the surgical efficiency. The mesh (10) possesses excellent mechanical properties and shaping ability. Moreover, a microporous structure facilitates the adhesion and migration of cells, reduces the rejection reaction of the body, and significantly reduces the incidence of capsular contracture.
