Artificial eye human body

Abstract

The present invention belongs to the field of medical device technology, and is especially one kind of artificial eye implanted directly into human body. The artificial eye is made with porous PTFE and has diameter of 1.2-2.5cm. It is made through the process of: mixing PTFE resin with sodium chloride in certain ratio, molding, sintering to obtain mixed material, forming into required shape, and boiling to eliminate sodium chloride to obtain the artificial eye. The artificial eye of the present invention is light, flexible, hydrophilic, air permeable, humidity permeable, tissue compatible, comfortable and good in wearing effect.

Description

technical field

[0001] The invention belongs to the technical field of medical devices, in particular to an artificial eye 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 It has 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 products; the treatment process takes less time; the price of grafts is moderate and people can accept them.
