Sapphire (Al₂O₃), nke nwere Mohs siri ike nke 9 (nke abụọ na diamond), ọnụọgụ dị ala nke mgbasawanye thermal (5.3 × 10⁻⁶ / K), na inertness, nwere ihe anụ ahụ na kemịkalụ kwụsiri ike yana njirimara nnyefe ọkụ sara mbara (0.15-5.5 μm). N'ịkwado site na ihe ndị a magburu onwe ya, sapphire ka anabatara nke ọma n'afọ ndị na-adịbeghị anya maka ịmepụta ngwa anya na njedebe dị elu, karịsịa mkpuchi windo nchebe ma ọ bụ mgbakọ oghere ebumnuche.

I. Isi uru Sapphire dị ka ihe maka Endoscopes siri ike

N'ime ngwa biomedical, a na-ejikarị sapphire eme ihe dị ka ihe bụ isi maka ngwa anya n'ime endoscopes siri ike dị elu, karịsịa maka windo nchebe ma ọ bụ lenses ebumnobi. Isi ike ya dị elu ma na-eyi nguzogide na-ebelata ihe ize ndụ nke ncha n'elu mgbe a na-akpakọrịta anụ ahụ, gbochie abrasion anụ ahụ kpatara site na iyi anya lens, ma nagide esemokwu ogologo oge site na ngwa ịwa ahụ (dịka ọmụmaatụ, forceps, mkpa), si otú ahụ na-agbatị ndụ ọrụ endoscope.

Sapphire na-egosipụta ọmarịcha biocompatibility; ọ bụ ihe na-adịghị cytotoxic inert nke nwere elu dị mma (na-enweta ihe siri ike nke Ra ≤ 0.5 nm mgbe polishing), nke na-ebelata nchikota anụ ahụ na ihe ize ndụ nke ọrịa mgbe ọ gasịrị. Nke a na-eme ka ọ dabaa ngwa ngwa na ọkọlọtọ biocompatibility ngwaọrụ ahụike ISO 10993. Nguzogide ya pụrụ iche na oke okpomọkụ na nrụgide, nke a na-ekwu na ọnụ ọgụgụ dị ala nke mgbasawanye ọkụ (5.3 × 10⁻⁶ / K), na-enye ya ohere ịtachi obi n'elu 1000 cycles nke nnukwu nrụgide steam sterilization na 134 ° C na-enweghị mgbawa ma ọ bụ mmebi arụmọrụ.

Ngwongwo anya pụtara ìhè na-enye sapphire ohere mgbasa ozi sara mbara (0.15-5.5 μm). Mbufe ya karịrị 85% n'ụdị ọkụ a na-ahụ anya, na-eme ka nchapụta onyonyo zuru oke. Ndekọ ntugharị dị elu (1.76 @ 589 nm) na-enyere mbelata oghere oghere dị nta, na-eme ka nhazi nke endoscopes dị ntakịrị.

II. Coating Technology Design

Na endoscopes siri ike, mkpuchi otu akụkụ (nke a na-etinye n'akụkụ na-adịghị emetụ anụ ahụ) na ihe ndị dị na sapphire bụ ihe ọhụrụ na-eme ka arụmọrụ na nchekwa dị mma.

1. Optical Functional Optimization on the Coated side

• Mkpuchi mgbochi nchegharị (AR):Etinye n'elu n'ime oghere nke oghere (n'akụkụ kọntaktị na-abụghị anụ ahụ), ọ na-ebelata reflectivity (ntụgharị uche nke otu n'elu <0.2%), na-eme ka nnyefe ọkụ na ọdịiche oyiyi dị, na-ezere mkpokọta mkpokọta site na mkpuchi ihu abụọ, ma na-eme ka nhazi usoro anya dị mfe.
• nkeMkpuchi Hydrophobic/Mgbochi Fog:Na-egbochi condensation n'elu oghere oghere n'ime n'oge ịwa ahụ, na-edobe anya nke ọma.

2. Safety Priority na akụkụ anaghị ekpuchi (Tissue Contact Side)

• Nchekwa ihe ndị dị n'ime Sapphire:Na-eji ezigbo ire ụtọ na kemịkalụ nkwụsi ike nke elu sapphire, na-ezere ihe egwu nke ịpụpụ mkpuchi n'ihi mmekọrịta ogologo oge na anụ ahụ ma ọ bụ ọgwụ nje. Na-ewepụ esemokwu nwere ike ịdị n'otu n'otu metụtara ihe mkpuchi (dịka ọmụmaatụ, metal oxides) na anụ ahụ mmadụ.
• Usoro nlekọta ndị dị mfe:Akụkụ na-enweghị mkpuchi nwere ike ịkpọtụrụ ndị na-ahụ maka ọgwụ nwere ike dị ka mmanya na hydrogen peroxide na-enweghị nchegbu maka mkpuchi mkpuchi.

III. Ihe ngosi nka na ụzụ dị mkpa maka nhazi na mkpuchi akụkụ sapphire

1.Sapphire Substrate Processing Requirements

• Izi ezi geometric: nnabata dayameta ≤ ± 0.01 mm (dayameta nkịtị maka obere endoscopes siri ike bụ 3-5 mm).
• Ịdị larịị <λ/8 (λ = 632.8 nm), Akụkụ Eccentric <0.1°.
• Ogo dị elu

2. Otu akụkụ mkpuchi usoro ụkpụrụ

• mkpuchi mkpuchi: Na-agafe ule ịkpụ obe ISO 2409 (Ọkwa 0, enweghị peeling).
• Mgbochi mgbochi: Mgbe 1000 usoro ịgba ọgwụ mgbochi dị elu, mgbanwe ntụgharị nke elu mkpuchi bụ <0.1%.
• Ihe mkpuchi mkpuchi na-arụ ọrụ: mkpuchi mgbochi ntụgharị kwesịrị ikpuchi oke ikuku nke 400-900 nm, yana nnyefe otu elu> 99.5%.

IV. Ntụle atụnyere na ihe ndị na-asọmpi (dịka, Glass Optical)

Tebụl na-esonụ na-atụnyere isi ihe nke sapphire na enyo anya ọdịnala (dị ka BK7):

V. Nzaghachi ụlọ ọgwụ na ntụzịaka nkwalite

1.Nzaghachi ngwa ngwa

• Nlele dọkịta na-awa ahụ:Sapphire siri ike endoscopes na-ebelata nke ọma ihe omume na-agbapụta oghere na ịwa ahụ laparoscopic, na-ebelata oge ọrụ. Elu kọntaktị enweghị mkpuchi na-egbochi nke ọma nrapado mucosal na ngwa endoscope ENT.
• Ọnụ nlekọta:Ọnụego nrụzi maka endoscopes sapphire na-ebelata ihe dịka 40%, n'agbanyeghị na ọnụahịa mbụ ịzụrụ dị elu.

2.Technical Optimization Directions

• nkeTeknụzụ mkpuchi ihe mejupụtara:Superimposing AR na mkpuchi mgbochi static n'akụkụ na-abụghị kọntaktị iji belata nchikota uzuzu.
• Nhazi Sapphire a na-ahụkarị:Na-emepe windo nchekwa sapphire gbagọrọ agbagọ ma ọ bụ gbagọrọ agbagọ ka ọ dabara na obere dayameta siri ike endoscopes (<2mm).

Mmechi

Sapphire abụrụla ihe bụ isi maka endoscopes siri ike dị elu n'ihi nguzozi zuru oke nke ike ike, biosafety na arụmọrụ anya. Ihe mkpuchi mkpuchi nke otu akụkụ na-eme ka mkpuchi dị elu iji kwalite arụmọrụ anya mgbe ị na-echekwa nchekwa obodo nke elu kọntaktị. Ụzọ a egosila na ọ bụ ihe ngwọta a pụrụ ịdabere na ya na-egbo mkpa ụlọ ọgwụ. Ka ọnụ ahịa nhazi sapphire na-ebelata, nkuchi ya na mpaghara endoscopy na-atụ anya na ọ ga-eto n'ihu, na-anya obere ngwa ịwa ahụ na-ebute nchebe na ogologo oge.
