Abstract
An ultrathin multi-hole silica gel ear support is used for ear reconstruction. Even micro holes are designed on the surface of the ear support. The ultrathin multi-hole silica gel comprises a complete helix, an antihelix and a cavum conchae structure. An auricle reconstructed by the support has the elasticity and compressibility of a normal auricle. When a patient sleeps, no ear cover is worn to protect the ear support, the risk of cutaneous necrosis caused by compression is avoided, and normal lift of the patient is greatly facilitated.
Description
Technical field
This utility model relates to a kind of ultra-thin porous silica gel ear supporter that reproduces for auricle.
Background technology
The auxiliary costicartilage support ear reconstruction of dilator has been popular, the most ripe ear reconstruction at present.But cutting from the body costicartilage is cost to sacrifice human normal tissue, operation increase patient suffering, wound big, pneumothorax danger is arranged, the auricle that reproduces is very thick, profile can not be done very clearly.Maximum shortcoming be the auricle that reproduces without any elasticity, can not be compressed, need wear the earmuff protection in bed throughout one's life, in case compressive deformation, cutaneous necrosis.
High density polyethylene (HDPE) (Medpor) ear supporter histocompatibility is good, and quality is light, and good toughness can arbitrarily cut, and is easy to sutured, the postoperative clear-cut, and profile is true to nature.But the outer helix part of postoperative is too stiff, and the chance that support exposes is more; Local skin is subject to crush routed, downright bad, in case the skin ulceration causes prosthese to expose, wound surface is difficult to spontaneous recovery.Also need wear earmuff protection in bed throughout one's life, in case compressive deformation, cutaneous necrosis.
The sixties in 20th century, silicone rubber is flexible because of it, histocompatibility is better, and the auricle that reproduces is flexible, can compress, and the Ceng Zuowei timbering material is applied to ear and reproduces.Being used for the silica gel ear supporter that auricle reproduces the sixties, is to form with normal auricle reverse mould, and most making are coarse, and thickness, hardness are bigger.Dilator also was not applied to during ear reproduces at that time, and the mastoid process that the silica gel ear supporter directly is put into without expansion is subcutaneous, and limited because of mastoid region skin, the tension force that the skin of rack surface bears is bigger, so be easy to ulceration, support exposes.In order to resist the tension force of skin, it is very soft that silica gel ear supporter at that time can not be done.A large amount of, poor skin that present skin expansion can provide is used for covering ear supporter.
In view of silica gel has certain intensity and toughness, its histocompatibility is better, and support is not yielding, can be compressed, if make ear supporter ultra-thin, porous, under skin expansion technology auxiliary, will become optimal ear supporter material.
Summary of the invention
For solve in the past silica gel ear supporter thickness, hardness is bigger, the shortcoming that is easy to expose, this utility model provides a kind of ultra-thin, Bio-sil ear supporter, there is uniform micropore on the surface, and complete helix, antihelix, cavity of auricular concha structure are arranged.
The technical scheme that its technical problem that solves this utility model adopts is: 1 this silica gel ear supporter is designed to thinner thickness, solves the problem that the auricle backing thickness was big in the past, hardness is big, can the danger that cutaneous necrosis, support expose not occur because of pressurized.2 these silica gel supports are designed to the surface uniform micropore, and the soft tissue on ear supporter both sides can heal together, erects fixation to propping up, even there is the small size skin ulcer also can heal voluntarily, reduces support and exposes.
The beneficial effects of the utility model are:
1 ultra-thin silicon secretory otitis media support, pliability is better, has elasticity, the compressibility of similar normal auricular cartilage.Patient needn't wear the earmuff protection during sleep, can not make things convenient for patient's orthobiosis greatly because dermonecrotic danger appears in pressurized.
2 are designed to intensive porous shape with silica gel support, the bulk strength that has kept ear supporter, reduced the weight of ear supporter, be conducive to both sides framework liquid drainage, the soft tissue on ear supporter both sides can heal together, erect fixation to propping up, even there is the small size skin ulcer also can heal voluntarily.
3 use ultra-thin, Bio-sil ear supporter down and carry out ear and reproduce in that skin dilator is auxiliary, owing to there is enough poor skin to cover the silica gel ear supporter, can avoid the silica gel ear supporter to expose, and therefore ear supporter can be done very thinly.The application of dilator becomes a reality the application of ultra-thin silicon secretory otitis media support.

Fig. 2: ultra-thin porous silica gel ear supporter back is seen.
The specific embodiment
This silica gel ear supporter is designed to the surface in Fig. 1, the example shown in Figure 2 uniform micropore, and complete helix, antihelix, cavity of auricular concha structure are arranged, though support is thin, has kept enough bulk strengths.
