Description
Technical field
The invention belongs to shaping cosmetic surgery fields, are related to a kind of method for customizing expander, in particular to a kind of application
Laser scanning, finite element analysis and 3D printing technique customization meet the method for the expander of biomethanics.
Background technique
Skin soft-tissue expansion abbreviation tissue expansion refers to and is implanted into skin tissue expander (abbreviation expander)
Under normal skin soft tissue, make it to surface to increase expander capacity to expansion intracapsular injection liquid by Injection valve
Skin soft tissue generates pressure, the effect by expanding mechanism to part, makes tissue and epidermal cell division and proliferation and cell
Gap widens, thus increase skin area, the reparation material that acquisition skin color, quality, structure, the area hair Jun Yushou match
Material.Skin expansion passes through development in 40 years, has been widely used in the reparation of the pathological tissues at each position of whole body at present
It is rebuild with organ.
Clinically common expander is mainly made of expansion capsule, Injection valve and aqueduct.Expanding capsule is expander
Main part can be divided into different specification and model according to its amount of capacity and form difference, common are rectangular, kidney shape and circle
Shape.
Existing expander has the following disadvantages:
The clinical scenario of local-pathological-changed tissues reparation is ever-changing, correctly selects extended region that can make the skin after expansion
Skin is fully used, and surgical effect is improved.The shape of most of donor sites is simultaneously irregular, although expander have different specification and
Model, but still changeable donor site is not adapted to, therefore, it is difficult to meet the needs of clinical practice.
From the perspective of expander design, the expander bottom surface of clinical use is mostly plane or arc at present, although energy
Fitting part body surface, but in many cases, such as the crown, shoulder joint and wall of the chest etc., expander bottom surface fails to paste well
The geometric shape of fit table, this will lead to following drawback: 1. expander stability reduce.2. expander is applied to bottom tissue
Pressure is uneven, and local nerve compression is excessive to lead to pain.
It can press to the skin on its surface when expander water filling expansion, if local skin is under pressure and excessive will cause blood
Obstacle is transported, so that this partial skin is easier to ulceration compared with surrounding skin.Expand the shape of capsule and the distribution of expansion skin pressure
It is closely bound up, if the excessive pressure that will increase its surface spreading skin and be subject to of expansion capsule part curvature.Expansion customization, structure
When more complicated expander, due to the preoperative effective assessment lacked for the distribution of skin pressure, complication is often resulted in
It is high-incidence, the consequences such as efficiency reduction.
Summary of the invention
It is an object of the present invention to overcome the deficiencies of the prior art and provide a kind of combination laser body surface scanning technique, limited
