Izinzuzo zohlelo lokusebenza kanye nokuhlaziywa kwe-Coating of Sapphire ku-Rigid Endoscopes

Uhlu Lokuqukethwe

1.Izakhiwo Eziyingqayizivele Zezinto Ze-Sapphire: Isisekelo Sokusebenza Okuphakeme Kwe-Endoscopes Eqinile

2.I-Innovative Single-Side Coating Technology: Ukuzuza Ibhalansi Engcono Kakhulu phakathi kokusebenza okubonakalayo kanye nokuphepha komtholampilo

3. Ukucutshungulwa okuqinile kanye nokucaciswa kwe-Coating: Ukuqinisekisa ukuthembeka kwe-Endoscope nokungaguquguquki

4.Izinzuzo Ezibanzi Ngaphezu Kwengilazi Yendabuko Yokukhanya: Kungani iSapphire iyisinqumo esiphezulu

5.Ukuqinisekiswa Komtholampilo kanye Nenguquko Yesikhathi Esizayo: Ukusuka Ekusebenzeni Okusebenzayo kuya ku-Technological Frontier

I-Sapphire (Al₂O₃), enobulukhuni be-Mohs obungu-9 (isibili kuphela ukuya kwedayimane), i-coefficient ephansi yokunweba okushisayo (5.3×10⁻⁶/K), kanye nokungangeni okungokwemvelo, inezinto ezibonakalayo ezizinzile namakhemikhali kanye nezici zokudlulisa ukukhanya okubanzi (0.15–5). Isekelwa yilezi zakhiwo ezinhle kakhulu, isafire iye yamukelwa kabanzi eminyakeni yamuva nje ekwenzeni izingxenye ze-optical kuma-endoscopes aqinile, ikakhulukazi amafasitela avikelayo noma ama-lens anenjongo.

I. Izinzuzo Eziyinhloko Ze-Sapphire Njengempahla Ye-Endoscopes Eqinile

Kuzinhlelo zokusebenza ze-biomedical, isafire ivamise ukusetshenziswa njengengxenye eyinhloko yezingxenye ze-optical kuma-endoscopes aqinile ekugcineni, ikakhulukazi kumafasitela avikelayo noma amalensi ahlosiwe. Ubulukhuni bayo obuphakeme kakhulu nokumelana nokuguga kunciphisa kakhulu ingozi yokuklwebheka kwendawo lapho uthintana nethishu, kuvimbela ukuhuzuka kwezicubu okubangelwa ukuguga kwamalensi, futhi imelane nokungqubuzana kwesikhathi eside kwamathuluzi okuhlinza (isb., ama-forceps, isikelo), ngaleyo ndlela andise impilo yesevisi ye-endoscope.

I-Sapphire ibonisa ukuhambisana okuhle kakhulu kwe-biocompatibility; kuyinto ye-inert engeyona i-cytotoxic ene-surface ebushelelezi kakhulu (ifinyelela ukuqina kwe-Ra ≤ 0.5 nm ngemva kokupholishwa), okunciphisa ukunamathela kwezicubu kanye nezingozi zokutheleleka kwangemva kokuhlinzwa. Lokhu kuyenza ihambisane kalula nezinga le-ISO 10993 le-biocompatibility yedivayisi yezokwelapha. Ukumelana kwayo okuyingqayizivele ekushiseni okuphezulu nokucindezela, okubangelwa i-coefficient ephansi yokwanda okushisayo (5.3 × 10⁻⁶/K), ivumela ukuthi ibekezelele imijikelezo engu-1000 ye-high-pressure sterilization ye-steam ku-134 ° C ngaphandle kokuqhekeka noma ukuwohloka kokusebenza.

Izici ezivelele ze-optical zenza isafire ngebanga elibanzi lokudlulisela (0.15–5.5 μm). Ukudluliswa kwayo kudlula ama-85% ku-spectrum yokukhanya okubonakalayo, iqinisekisa ukukhanya okwanele kwesithombe. Inkomba ye-refractive ephezulu (1.76 @ 589 nm) inika amandla irediyasi yokugoba ilensi encane, yenza kube lula ukwakheka okuncane kwama-endoscopes.

II. I-Coating Technology Design

Kuma-endoscope aqinile, ukunamathela ohlangothini olulodwa (okuvame ukusetshenziswa ohlangothini olungaxhumani nethishu) ezingxenyeni zesafire kuwumklamo omusha olinganisela ukusebenza nokuphepha.

1.Optical Functional Optimization on the Coated Side

• I-Anti-Reflection (AR) Coating:Idiphozithwe endaweni engaphakathi yelensi (uhlangothi lokuthintana okungelona izicubu), inciphisa ukubukeka (ukubukeka kobuso obubodwa <0.2%), ithuthukisa ukudluliswa kokukhanya nokugqama kwesithombe, igwema ukubekezelelana okunqwabelanayo okuvela ekuhlanganisweni okunezinhlangothi ezimbili, futhi yenza lula ukulinganiswa kwesistimu yokubona.
• .I-Hydrophobic/Anti-Fog Coating:Ivimbela ukuminyanisa endaweni yangaphakathi yelensi phakathi nokuhlinzwa, igcina indawo yokubuka ecacile.

2.Ukuphepha Okubalulekile Ohlangothini Olungamboziwe (Uhlangothi Lokuxhumana Kwezicubu)​

• Ukulondolozwa Kwezakhiwo Ezingokwemvelo Ze-Sapphire:Isebenzisa ubushelelezi obuphezulu bomdabu kanye nokuzinza kwamakhemikhali endaweni yesafire, igwema izingozi zokuxebuka kokumboza ngenxa yokuxhumana isikhathi eside nezicubu noma izibulala-magciwane. Iqeda izingxabano ezingaba khona ze-biocompatibility ezihlobene nezinto zokumboza (isb, ama-oxide ensimbi) kanye nezicubu zomuntu.
• Izinqubo Zokulungisa Esenziwe Lula:Uhlangothi olungamboziwe lungathinta ngokuqondile izibulala-magciwane ezinamandla njengotshwala ne-hydrogen peroxide ngaphandle kokukhathazeka ngokugqwala.

III. Izinkomba Zobuchwepheshe Ezibalulekile Zokucubungula Nokufakwa Kwengxenye yeSapphire

1.Izimfuneko Zokucubungula I-Sapphire Substrate

• Ukunemba Kwejiyomethri​: Ukubekezelela Ububanzi ≤ ±0.01 mm (amadayamitha avamile wama-endoscopes amancane aqinile angu-3–5 mm).
• Flatness​ < λ/8 (λ = 632.8 nm), ​​I-Eccentric Angle< 0.1°.
• Ikhwalithi Yokuphezulu: Ukuqina Ra ≤ 1 nm endaweni ethinta izicubu ukuze kugwenywe imihuzuko emincane edala ukulimala kwezicubu.

2. Amazinga Enqubo Yokuhlanganisa Ohlangothi Olulodwa

• I-Coating Adhesion: Iphumelela ukuhlolwa kwe-ISO 2409 (iBanga 0, akukho ukuxebuka).
• I-Sterilization Resistance​: Ngemva kwemijikelezo engu-1000 yokuvala inzalo yokucindezela okuphezulu, ukuguqulwa kokubonakala kwendawo emboziwe kungu-<0.1%.
• I-Functional Coating Design​: I-anti-reflection kufanele imboze ibanga le-wavelength elingu-400–900 nm, ngokudluliswa kwe-single-surface> 99.5%.

IV. Ukuhlaziya Okuqhathanisayo Nezinto Zokuncintisana (isb., Ingilazi ye-Optical)​

Ithebula elilandelayo liqhathanisa izici ezibalulekile zesafire kanye nengilazi yendabuko yokubona (njenge-BK7):

V. Impendulo Yomtholampilo kanye Neziqondiso Zokuthuthukisa

1.Impendulo Yesicelo Esisebenzayo

• Ukuhlolwa Kodokotela Ohlinzayo:Ama-endoscope aqinile e-Sapphire anciphisa kakhulu izehlakalo zokufiphalisa ilensi ekuhlinzweni kwe-laparoscopic, afinyeze isikhathi sokusebenza. Indawo yokuxhumana engavaliwe ivimbela ngempumelelo ukunamathela kwe-mucosal ezinhlelweni ze-ENT endoscope.
• Izindleko Zokulungisa:Amanani okulungisa ama-sapphire endoscopes ehliswa cishe ngo-40%, nakuba izindleko zokuthenga zokuqala ziphezulu.

.

2.Izikhombisi-ndlela Zokuthuthukisa Ubuchwepheshe

• .I-Composite Coating Technology:I-AR ephakeme kakhulu kanye nama-anti-static coatings ohlangothini olungathinteki ukunciphisa ukunamathela kothuli.
• I-Atypical Sapphire Processing:Ukuthuthukisa amafasitela avikelayo esafire agobile ukuze avumelane nama-endoscopes amancane aqinile (< 2 mm).

Isiphetho

I-Sapphire isiphenduke into esemqoka yama-endoscopes aqinile ngenxa yebhalansi yawo ephelele yobulukhuni, i-biosafety, nokusebenza kokubona. Idizayini yokumboza yohlangothi olulodwa isebenzisa ama-coatings ukuze kuthuthukiswe ukusebenza kahle kokubona kuyilapho ilondoloza ukuphepha komdabu kwendawo yokuxhumana. Le ndlela ibonakale iyisixazululo esithembekile esihlangabezana nezidingo zomtholampilo. Njengoba izindleko zokucutshungulwa kwesafire zincipha, ukwamukelwa kwayo emkhakheni we-endoscopy kulindeleke ukuthi kukhule ngokuqhubekayo, kuqhubekisele phambili amathuluzi okuhlinza angangeneleli kancane abheke ekuphepheni okukhulu nokuhlala isikhathi eside.
