Abstract
A marmen auricle for repairing damaged auricle or preparing artificial auricle is made up from marmen wire through braiding to form a netted structure similar to human auricle or the shape of a certain part. Its advantages are very strong power to keep the shape of auricle, fine moulding, elasticity and flexibility, and high durability.
Description
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.
In the prior art, the supporting mould when repairing auricle or rebuilding auricle with human body autologous tissue, have usually 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.Another processing mode is to wear the false ear of silicone rubber, though good simulation needs periodic replacement, and is false ear.
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:
Memory alloy auricle, the typing supporting mould when relating to human body autologous tissue's repair deficiency auricle or reconstruction auricle comprises memory alloy auricle forming supporter, auricle fixing head, external auditory meatus forming supporter, orthopaedics curium nail hole, location hook.The memory alloy auricle forming supporter is the network structure similar to a certain partial shape of human body auricle or auricle of memory alloy wire or fibrage; The auricle fixing head is with the plane that has orthopaedics curium nail hole and location hook of memory alloy wire braiding or curved surface network structure or the plane or the curved-surface structure that have orthopaedics curium nail hole and location hook made with medical metal material or macromolecular material or pottery; 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; Memory alloy auricle forming supporter, auricle fixing head, external auditory meatus forming supporter can be the overall structures of memory alloy wire braiding, also can be three parts independently, interconnect by location hook and tolerance fit.
---above-mentioned memory alloy auricle forming supporter also can be the similar network structure of a certain partial shape of or auricle similar to the auricle shape through the laser engraving of the heat treated memorial alloy thin-walled part of typing.
---above-mentioned memory alloy auricle forming supporter can be the monolayer network structure of memory alloy wire braiding, also can be double-deck network structure or multilamellar network structure.
---above-mentioned memory alloy auricle forming supporter can be the network structure of integral weaving, also can be the cancellated assemblys of several separate, knitted.
---above-mentioned memory alloy auricle forming supporter can be the similar loose-leaf system network structure of certain a part of shape to human body auricle or auricle of memory alloy wire braiding.The memory alloy auricle of this structure can be an integral weaving, also can be two auricle forming supporters that cooperatively interact that weave respectively.
---above-mentioned memory alloy auricle forming supporter can have different weaving manners and porosity.
---above-mentioned memory alloy auricle forming supporter also can link to each other with the external auditory meatus forming supporter.
---above-mentioned memory alloy auricle forming supporter also can be connected and fixed seat near the external auditory meatus opening part.
---also can have through hole on the auricle fixing head of above-mentioned memory alloy auricle, the growth of being convenient to tissue covers.Plane or curved-surface structure that the characteristics of auricle fixing head are to have orthopaedics curium nail hole or have orthopaedics curium nail hole and the location hook that is connected with auricle forming supporter or external auditory meatus forming supporter.According to clinical different needs, can there be different designs and connected mode in orthopaedics curium nail hole with location hook, and the auricle fixing head can have different geometric shapes.
---above-mentioned memorial alloy typically refers to the NiTi marmem, and its recovery temperature can be between-20 ℃～45 ℃, usually between 15 ℃～35 ℃; The diameter of NiTi shape-memory alloy wire is between 0.001～1mm; According to clinical concrete needs, the NiTi marmem also can substitute with other elastic materials.
The present invention's memory alloy auricle 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.
