Preparing method of full-autologous tissue dual-layer envelope suitable breast prosthesis

Abstract

The invention discloses a preparing method of full-autologous tissue dual-layer envelope suitable breast prosthesis. Autologous skin epidermis layer and corium layer tissue and subcutaneous fatty tissue are taken from a patient according to the pre-estimated excision extension and mass, the epidermis layer tissue and skin-removed layer fatty tissue are placed in a sterile container, then the sterile container is placed in a water bath tank at 50-60 DEG C for warm bath for 20-40 min for deactivation, deactivated autologous fatty tissue is modified and sewn to form an object obtained in the suitable breast prosthesis with the required shape and size, the deactivated skin epidermis layer tissue is sewn to form an inner layer envelope sac for the object obtained in the suitable breast prosthesis according to the shape and size of the object obtained in the suitable breast prosthesis, and the corium layer is sewn to form an outer layer envelope sac for the object obtained in the suitable breast prosthesis. By means of the method, the immersion of inflammatory cells of surrounding tissue can be prevented after the prosthesis is implanted, the inflammatory reaction probably happening to the object contained in the prosthesis is prevented, the prosthesis is free of piercing and breaking risks, and the toughness, elasticity, appearance maintaining capacity and resistance capacity of squeezing and other external injuries of the prepared prosthesis are improved.

Description

technical field [0001] The invention belongs to the technical field of human body prostheses, and in particular relates to a method for manufacturing a fully autologous tissue double-coated conformable breast prosthesis. Background technique [0002] The benign and malignant lesions of the breast require surgical resection of part or all of the glands. After surgery, the shape of the breast will be partially collapsed and pitted due to the partial loss of the glands, and the nipples will be deflected and retracted. When the shape of the breast is unacceptably poor, the whole mastectomy is forced to be performed, with serious consequences. After part of the gland is lost, the existing remedy is to transfer the ipsilateral latissimus dorsi muscle flap to fill the missing area, that is, plastic surgery, but currently there is no suitable conformal filling prosthesis available. After all the glands are missing, there are silicone gel prosthesis implantation, pedicled myocutaneo...

AI Technical Summary

Problems solved by technology

Autologous tissue flap mammoplasty is used for mammoplasty after partial glandectomy. Tissue flap surgery requires autologous ipsilateral neurovascular-pedicled latissimus dorsi myocutaneous flap or rectus abdominis myocutaneous flap to be transferred to fill the missing gland area, which will damage the structural integrity of the donor site, including appearance beauty, sensory and motor functions etc. Increased surgical trauma and surgical complications include partial or complete necrosis of the transferred musculocutaneous flap, increased scarring at the donor site, long-term subcutaneous fluid accumulation, and disused atrophy of the transferred muscle, resulting in unsatisfactory shaping results
