Description
Technical field
The invention belongs to field of medical technology, particularly relate to a kind of personalized wound surface orthopedic instruments and preparation method thereof, can be used for prevention and repair scar hyperplasia.
Background technology
Scar hyperplasia mainly because collagen fiber increase too much, and arranges with spiral or nodositas form, thus forms the irregular cicatrix higher than normal skin surface.Cicatrix grand go out normal skin, out-of-shape, the benign tumors that colour generation is red, matter is hard, severe patient, with symptoms such as contracture, pruritus, pain, if undue growth, then can affect appearance or cause dysfunction, even may canceration.In order to prevent and repair scar hyperplasia, the method for extensive use is clinically pressure silica gel therapy, and it not only can be used for the cicatrix repairing hypertrophy, improves symptom, alleviates the height of hypertrophy, hardness and color, more can be used for preventing injuries the scar hyperplasia after healing.This may be because pellosil serves scar tissue mechanical pressure, the effect increasing humidity and reduction partial pressure of oxygen.
In actual applications, the situations such as the position according to cicatrix, shape and size are usually needed to use the Silica hydrogel pad pasting being close to wound surface, especially for the burning wound site of the complicated shapes such as face, extremities joint and axillary fossa.In the cicatrix of health different parts, face scar to leave over the wound brought patient the most serious.Nowadays, pressure silica gel mask is the effective means suppressing and repair facial scar hyperplasia.Pressure silica gel mask is made up of inside and outside double-layer structure, and internal layer is soft medical silica-gel material, and skin is the hard and transparent plastic plate of quality.Then with elastic reducing-fixing band, pressure silica gel mask is fixed on patient facial region, is changed facial scar tissue applied pressure by the elasticity of adjustable elastic fixing band.
But, the facial characteristics complexity of people is various, market is sold pressure silica gel mask and but there is fixed dimension usually, and size is comparatively single, be difficult to be close near the eyes, nose week and lip below etc. depressed area, thus cause pressure to reduce, exert pressure inequality even without pressure, the effect of preventing and repairing scar hyperplasia is greatly affected.In addition, conventional pressure silica gel mask is all change by the elasticity of adjustable elastic fixing band size of exerting pressure, and the too small meeting of pressure causes scar hyperplasia and poor effect, and pressure is excessive, and local blood circulation can be made smooth, causes pressure ulcers.Further, regulate in this way and to exert pressure size, institute exerts pressure and usually has uncertainty, cannot quantize to show, and can not meet the quantification demand that needed for the different and different wound site of wound surface pressure needed for different phase in recovery process, pressure is different.Therefore, this size is fixed and carried out the exert pressure application of pressure silica gel mask of size of sense organ by the elasticity of adjustable elastic fixing band has certain defect, to be difficult to meet on market the demand that and pressure personalized to it quantizes display.
