Overview
Organization transplantation includes skin transplantation, bone and cartilage transplantation, leather and fat transplantation, mucosal transplantation, fascia transplantation, muscle transplantation, nerve transplantation, composite tissue transplantation, biological material filling Initiation and tissue engineering organization transplantation.
Skin transplant is one of the most used autologous tissue transplantation methods. It can be divided into free leather transplant, two categories of flap transplant. The latter can also be divided into three types of strap, free and tubular flap transplant.
Explanation
The deformity or tissue defect caused by congenital or postaine factors can lead to functional disorders of the body, and the traditional solution is autologous tissue transplantation, although satisfactory results can be achieved, It is a "demolition of the wall to make up the West Wall" at the expense of autologous health, which will lead to many complications and additional damage.
Artificial biomaterials are filled in one of the most popular programs, but the body's reactions to artificial materials are the first problem that is urgent to solve in clinical applications.
Tissue Engineering Organization is gradually emerging with the development of tissue engineering. The organizational engineering is a new technique for a combination of medical workers developed in the 1990s. Applying this technique can form biological tissues in vivo to complete human tissue defects. The advantage is that:
1 can form a vital living tissue, forming a form, structure, and function of the abrasion tissue and reaching permanent substitution;
2 can be used in a small amount Tissue cells, repair large tissue defects, achieve minimally invasive repair and function reconstruction;
3 can be placed in accordance with tissue defects, reaching the form of repair. Despite the great progress in tissue engineering bones and cartilage, however, to date, tissue-engineered tissue retaining defects, there is also a gap between clinical requirements. The main problem is that seed cells can continue to proliferate after a certain passage, so that it is difficult to solve large or large-scale tissue defects.
