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
The invention belongs to technical field of medical instruments, be specifically related to a kind of directly ocular prosthesis of implant into body.
Background technology
Politef is the polymer of tetrafluoroethene.English abbreviation is PTFE.Structural formula is
It has splendid chemical stability, excellent biological compatibility, and broad operative temperature can not wear out, and is forever durable.
Elson in 1988 have proposed the standard of ideal soft tissue filling material: graft and receptor tissue are compatible and can coexist with connective tissue; Minimum foreign body reaction and anaphylaxis; Therapeutic process does not have pain; Clinical rectification effect is lasting; The non-composite of graft; Therapeutic process is consuming time few; The graft moderate cost, people can accept.
Expanded PTFE (expanded polytetrafluoroethylene, e-PTFE) be the ultrastructure that " saves and fiber " by the expanded generation of politef drawn, become a kind of tough and porous new material, it is beyond imagination tough and tensile that its high fiberization has it, and kept the particular performances of politef own.
Through secular experimentation and clinical observation, e-PTFE is as the soft tissue filler for proof, the report of anaphylaxis and toxic reaction does not take place, no carcinogenic and teratogenesis, rare rejection and inflammatory reaction, its elasticity, hardness and soft tissue are approaching, can the grow into micropore of e-PTFE of the cell of surrounding tissue, it is movable to make it to be difficult for, and does not form tangible fiber kystis after implanting, can also intactly take out in case of necessity, therefore in cosmetic plastic surgery, obtain extensive use.But, seriously limited popularizing of e-PTFE because imported material costs an arm and a leg.
The FDA approval is produced and obtained to expanded PTFE early than the company of Ge Er company (GORE) by the U.S. in 1969.Expanded PTFE surgery embedded material is the invention in 1975 of GORE company and creates that it at first is applied to clinical as artificial blood vessel.Because biocompatibility is good, the eighties of last century early eighties begins, and western countries are applied to cosmetic plastic surgery, treatment facial area soft tissue defects and depressed deformity, be applied as manyly with nose, temporo, volume, chin, lip, ear and nasolabial fold portion, obtained excellent curative.In China, 1997 begin to have e-PTFE to be applied to the report of cosmetic plastic surgery.
Enucleation of eyeball is helpless to the doctor, is cruel to patient.It is that the someone has extractd eyeball because of tumor because of wound that the people is arranged among them.Their eye socket will cave in behind the eyeball excise, makes the patient who hit by health be subjected to wound, especially some children of soul, and they can't bear this double blow at immature soul.At this time, they can make them original image not have change at least for installing ocular prosthesis (prosthese).
Wearing the purpose of ocular prosthesis, is the appearance of pursuing the true, the good and the beautiful, by the installation of ocular prosthesis, recovers normal outward appearance, overcomes the phychology of feeling oneself inferior, and learns, works and participate in social comings and goings by normal person's psychology.Ocular prosthesis is except remedying the appearance deficiency, and it also brings into play its important function.Prevent the soft tissue degeneration that eye socket remains, prevent that eyelid and eyelash from inwardly growing, help tear water technology to continue to do in clean cycle and the eye socket and the eyelid lubricate.
The main material of making ocular prosthesis at present is silica gel and hydroxyapatite (HA).The ocular prosthesis of these material, its histocompatibility, flexibility, breathability etc. are not ideal enough.
Summary of the invention:
The object of the present invention is to provide a kind of light weight, softness of implant into body, hydrophilic, ventilative, saturating wet, ocular prosthesis that histocompatibility is good, and this ocular prosthesis wear conveniently, comfortable, outward appearance is full, attractive in appearance, effect is excellent.
The ocular prosthesis of implant into body provided by the invention adopts porous Teflon to prepare, and sphere diameter is 1.2-2.5cm.This ocular prosthesis materials used novelty, and have for many years clinical practice as embedded material.It is many to make ocular prosthesis implant hole, more approaches human tissue structure, and its vascularization speed is fast, and human body is not had the inflammatory of causing and sensitization, is the novel succedaneum of ocular prosthesis implant.
The preparation method of the ocular prosthesis that the present invention proposes is as follows: with the abundant mix homogeneously of PTFE resin and analytical pure sodium chloride process screening back, the sodium chloride mass content is 55%～65%, and the sodium chloride particle diameter is 0.02mm～0.03mm; Through 100kg/cm
2～200kg/cm
2The pressure mold pressing, 327 ℃～385 ℃ sintering 1～4 hour; Processing then (as cutting) becomes the shape of various needs, and the reuse distilled water boils, and sloughs the sodium chloride in the product, thereby forms needed porous ocular prosthesis.
Show that after testing this ocular prosthesis has light weight, softness, ventilative, advantage that tissue compatible is good.
The specific embodiment
Embodiment 1, will contain the PTFE resin and the abundant mix homogeneously of sodium chloride of 55% sodium chloride, and the sodium chloride particle diameter is 0.02mm～0.03mm; Through 100kg/cm
2～120kg/cm
2The pressure mold pressing, 327 ℃～350 ℃ sintering 4 hours; Get composite material.It is ocular prosthesis about 1.5cm that cooling back adopts the cutter cutting method to be processed into sphere diameter, and the steaming method of reburning is removed sodium chloride.Prepared ocular prosthesis has aforementioned premium properties.
Embodiment 2, will contain the PTFE resin and the abundant mix homogeneously of sodium chloride of 60% sodium chloride, and the sodium chloride particle diameter is 0.02mm～0.03mm; Through 180kg/cm
2～200kg/cm
2The pressure mold pressing, 370 ℃～385 ℃ sintering 2 hours; Get composite material.The cooling back adopts the cutter cutting method to be processed into the ocular prosthesis that sphere diameter is 2.5cm, and reuse is hotted plate method, removes sodium chloride.Prepared ocular prosthesis has aforementioned same premium properties.
Embodiment 3, will contain the PTFE resin and the abundant mix homogeneously of sodium chloride of 65% sodium chloride, and the sodium chloride particle diameter is 0.02mm～0.03mm; Through 350 ℃～360 ℃ sintering 1 hour, composite material.It is ocular prosthesis about 2.2cm that cooling back adopts the cutter cutting method to be processed into sphere diameter, and the steaming method of reburning is removed sodium chloride.Prepared ocular prosthesis has aforementioned premium properties.
