Embodiment 1

[0016] Embodiment 1, using a nickel-titanium alloy wire with a diameter of 0.3mm, first winding it into the structural shape of an ear, and then passing an e-PTFE tube with an outer diameter of 1.1mm on the above-mentioned alloy wire wound into an ear shape to obtain the obtained Composite ear braces are required. It is inserted in the same way as a normal ear prosthesis. The obtained ear prosthesis has the aforementioned excellent properties.

Embodiment 2

[0017] Embodiment 2, using a nickel-titanium alloy wire with a diameter of 1mm, first winding it into the structural shape of an ear, and then using an e-PTFE tube with an outer diameter of 3.0mm to wear it on the above-mentioned alloy wire wound into an ear shape to obtain the required Composite ear support is added. It is inserted in the same way as a normal ear prosthesis. The obtained ear prosthesis has the same excellent performance as above.

Abstract

A composite ear supporting frame with high tissue compatibility is made up of a Ni-Ti alloy wire inserted in a teflon tube through curving it to become ear shape.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a composite ear support that can be directly implanted into a human body. Background technique [0002] PTFE is a polymer of tetrafluoroethylene. English abbreviation is PTFE. The structural formula is Expanded polytetrafluoroethylene (expanded polytetrafluoroethylene, e-PTFE) is a kind of strong and porous new material, which is highly fibrous. It is hardened beyond imagination and maintains the unique properties of PTFE itself - excellent chemical stability, good biocompatibility, wide operating temperature, no aging, and permanent durability. [0003] In 1988, Elson proposed the ideal standard for soft tissue filling materials: grafts are compatible with recipient tissues and can coexist with connective tissue; minimal foreign body reactions and allergic reactions; no pain during treatment; long-lasting clinical correction effects; non-synthetic grafts ...
