Abstract
The present invention relates to a memory alloy auricle particularly to a shaping and supporting mould when a defective auricle is repaired with human own tissues or an auricle is reconstructed. Because a reticular structure which is knitted by memory alloy wires and has similar shape to human auricles or a certain part of auriculars is adopted, the memory alloy auricle not only has super strong shape keeping capacity and is capable of perfectly reproducing the design shape of the auricles, but also has favorable elasticity and pliability. The present invention is capable of preferably repairing defective auricles or reconstructing auricles, and has the advantages of beautiful appearance, perdurability and durability. The memory alloy auricle is an ideal mould for repairing and supporting auricles.
Description
Technical field
Supporting mould when the present invention relates to a kind of human organ and repairing is particularly with human body autologous tissue's repair deficiency auricle or the typing supporting mould when rebuilding auricle.
Background technology
In the prior art, supporting mould when repairing auricle or rebuilding auricle with human body autologous tissue, usually have polyethylene porous supporting mould, human body self cartilaginous tissue after carving as supporting mould etc., because these supporting moulds lack flexibility, make human body auricle after the reparation lose the due pliability of auricle, emulation is poor, clinical application effect is not good.And Japan Patent JP10014971 discloses a kind of ear appliance, this ear appliance uses the memorial alloy line to make, it is striven right user and is existing ear, but ear has deformities, it is excessive to incline forward or backward as auricle, or auricle subsides, twists or the like state, this appliance is the wheel profile strip-shaped bracket bar of one section ear corridor of ear deformity part, place people's deformity of ear state part, reset in order to support the aural deformity position, but can not rebuild, repair the patient who does not have the ear outward appearance fully.Another processing mode is to wear the false ear of silicone rubber, though good simulation needs periodic replacement, and is false ear.
Summary of the invention
Typing supporting mould when the objective of the invention is to provide a kind of usefulness human body autologous tissue's repair deficiency auricle or rebuilding auricle substitutes auricular cartilage.It can not only support the human body self tissue effectively, forms the shape of auricle; And can keep the shape of auricle for a long time, and have good pliability and elasticity, particularly after distortion, can recover the design shape of auricle automatically, have fabulous emulation.
The object of the present invention is achieved like this:
A kind of memory alloy auricle, include the auricle forming supporter, the auricle forming supporter be memory alloy wire or memorial alloy fibrage to the similar network structure of human body auricle shape, the auricle fixing head is provided with orthopaedics curium nail hole and location hook, the auricle fixing head is plane or curved-surface structure, the external auditory meatus forming supporter is the pipe type netted structure similar to the external auditory meatus shape with the memory alloy wire braiding, the auricle forming supporter connects the auricle fixing head by location hook and tolerance fit, the auricle fixing head connects the external auditory meatus forming supporter by location hook and tolerance fit, memory alloy wire is meant that recovery temperature is between-20 ℃～45 ℃, the memorial alloy of diameter between 0.001～1mm, the auricle forming supporter coats with flap.
The present invention's memory alloy auricle can be for the patient that do not have the ear outward appearance fully, inserts a complete human body ear corridor near patient's earhole, utilizes the human body self tissue repair, coats function, coats this complete ear corridor as flap.The present invention is owing to adopted the netted braiding structure of the memorial alloy similar to a certain partial shape of auricle or auricle as rebuilding with human body autologous tissue or shaping material when repairing auricle, substitute the auricular cartilage of damaged human body self, used the memorial alloy excellent biological compatibility dexterously, the phase transformation super-elasticity, shape memory particularly, make the new auricle of formation can not only reproduce the design shape of auricle fully, and overcome existing auricle and rebuild supporting mould and can not be out of shape, pliability is poor, inelastic shortcoming, and has a good biocompatibility, good springiness, pliability is good, the advantage that the shape hold facility is strong, particularly after the distortion, under the effect of body temperature, can recover the design model of auricle automatically, make the good simulation of newly-built auricle, reached the purpose that auricle is rebuild or repaired, can extensive use in plastic operation or the operation of department of eye otology.
