I-Sapphire (Al₂O₃), enobunzima be-Mohs obuyi-9 (eyesibini emva kwedayimani), i-coefficient ephantsi yokwandiswa kobushushu (5.3×10⁻⁶/K), kunye nokungakwazi ukusebenza kakuhle, ineempawu zomzimba nezekhemikhali ezizinzileyo kakhulu kunye neempawu zokudlulisa ukukhanya okubanzi (0.15–5.5 μm). Ixhaswa zezi mpawu zibalaseleyo, i-sapphire iye yasetyenziswa kakhulu kwiminyaka yakutshanje ekwenzeni izinto ezibonakalayo kwii-endoscopes eziqinileyo eziphezulu, ngakumbi izigqubuthelo zeefestile ezikhuselayo okanye iindibano zeelensi ezijolise ngqo.

I. Iingenelo eziphambili zeSapphire njengezinto ezisetyenziswa kwi-Endoscopes eqinileyo

Kwizicelo zonyango, i-sapphire isetyenziswa rhoqo njengesiseko esiphambili sezinto ezibonakalayo kwii-endoscopes eziqinileyo eziphezulu, ngakumbi kwiifestile ezikhuselayo okanye iilensi ezijolise kuzo. Ubunzima bayo obuphezulu kakhulu kunye nokumelana nokuguguleka kunciphisa kakhulu umngcipheko wokukrweleka komphezulu ngexesha lokudibana nezicubu, kuthintela ukugruzuka kwezicubu okubangelwa kukuguguleka kweelensi, kwaye kumelane nokungqubana kwexesha elide okuvela kwizixhobo zotyando (umz., ii-forceps, izikere), ngaloo ndlela kwandisa ubomi benkonzo ye-endoscope.

I-Sapphire ibonakalisa ukuhambelana okuhle kakhulu kwezinto eziphilayo; yinto engenabungozi kwi-cytotoxic ene-surface egudileyo kakhulu (efikelela kwi-Ra ≤ 0.5 nm emva kokupholisha), nto leyo enciphisa ukunamathela kwezicubu kunye neengozi zosulelo emva kotyando. Oku kwenza ukuba ihambelane ngokulula nomgangatho we-ISO 10993 we-biocompatibility yesixhobo sezonyango. Ukumelana kwayo okukhethekileyo kubushushu obuphezulu kunye noxinzelelo, okubangelwa yi-coefficient ephantsi yokwandiswa kobushushu (5.3×10⁻⁶/K), kuyivumela ukuba inyamezele imijikelo engaphezu kwe-1000 yokucoca umphunga ngoxinzelelo oluphezulu kwi-134°C ngaphandle kokuqhekeka okanye ukonakala kokusebenza.

Iimpawu ezibalaseleyo zokukhanya zinika isafire enoluhlu olubanzi lokudlulisa (0.15–5.5 μm). Ukudlulisa kwayo kudlula i-85% kwi-spectrum yokukhanya okubonakalayo, okuqinisekisa ukukhanya okwaneleyo komfanekiso. Isalathisi esiphezulu sokuqaqamba (1.76 @ 589 nm) senza i-radius encinci yokugoba kwelensi, nto leyo eququzelela uyilo oluncinci lwee-endoscopes.

II. Uyilo lweTekhnoloji yokuGcoba

Kwii-endoscopes eziqinileyo, uboya obunecala elinye (obudla ngokusetyenziswa kwicala elingadibaniyo nezicubu) kwizinto zesafire luyilo olutsha olulinganisela ukusebenza kunye nokhuseleko.

1. Ukulungiswa kokusebenza kwe-Optical kwicala eligutyungelweyo

• Ukwaleka okuchasene nokubonakalisa (i-AR):Ifakwe kumphezulu ongaphakathi welensi (icala elingenanto yokuthintana nezicubu), inciphisa ukubonakaliswa (ukubonakaliswa komphezulu omnye < 0.2%), iphucula ukuhanjiswa kokukhanya kunye nomahluko womfanekiso, ithintela ukunyamezelana okuqokelelweyo okuvela kumbala omacala amabini, kwaye yenza lula ukulinganiswa kwenkqubo ye-optical.
• .Ukwambathisa i-Hydrophobic/Anti-Inkungu​​:Ithintela ukufuma kumphezulu welensi yangaphakathi ngexesha lotyando, igcina indawo ebonakalayo ecacileyo.

2. Ukhuseleko oluPhambili kwicala elingagqunywanga (Icala loQhagamshelwano lweTissue)​

• Ukugcinwa kweempawu zeSapphire:Isebenzisa ukuthamba okuphezulu kunye nokuzinza kweekhemikhali kumphezulu wesafire, ithintela iingozi zokuxobuka ngenxa yokudibana ixesha elide nezicubu okanye izibulali-ntsholongwane. Iphelisa iingxabano ezinokubakho malunga nokuhambelana kwezinto zokugquma (umz. ii-oxide zesinyithi) kunye nezicubu zabantu.
• Iinkqubo Zokulungisa Ezilula:Icala elingagqunywanga linokunxibelelana ngokuthe ngqo nezibulali-ntsholongwane ezinamandla ezifana notywala kunye ne-hydrogen peroxide ngaphandle kokuxhalabela ukugqwala kokugqunywa.

III. Iimpawu zoBugcisa eziphambili zokuCwangciswa kweSapphi kunye nokuGcoba

1. Iimfuno zokuSebenza ngeSapphire Substrate​​

• Ukuchaneka kweJiyometri: Ukunyamezelana kobubanzi ≤ ±0.01 mm (ububanzi obuqhelekileyo bee-endoscopes ezincinci eziqinileyo yi-3–5 mm).
• Ukuthe tyaba​ < λ/8 (λ = 632.8 nm), i-Eccentric Angle< 0.1°.
• Umgangatho womphezulu: Uburhabaxa beRa ≤ 1 nm kumphezulu wokudibana kwezicubu ukuze kuthintelwe ukukrweleka okuncinci okubangela umonakalo kwizicubu.

2. Imigangatho yeNkqubo yokuGcoba ecaleni elinye

• Ukuncamathelisa iCoating: Iphumelele uvavanyo lwe-ISO 2409 olunqamlezileyo (iBanga 0, akukho kuxobuka).
• Ukumelana nokubulala iintsholongwane: Emva kwemijikelo yokubulala iintsholongwane yoxinzelelo oluphezulu eyi-1000, utshintsho lokubonakalisa komphezulu ogqunyiweyo luyi-<0.1%.
• Uyilo Lokugquma Olusebenzayo: Ukugquma okuthintela ukubonakaliswa kufuneka kugubungele uluhlu lwamaza angama-400–900 nm, kunye nokudluliselwa kobuso obunye > 99.5%.

IV. Uhlalutyo lokuthelekisa kunye nezixhobo zokhuphiswano (umz., iGlasi yokukhanya)​

Le theyibhile ilandelayo ithelekisa iipropati eziphambili zesafire kunye neglasi yendabuko ye-optical (njenge-BK7):

V. Ingxelo yeKliniki kunye neMiyalelo yoPhuculo

1. Impendulo yesicelo esisebenzayo

• Uvavanyo loGqirha:Ii-endoscopes eziqinileyo zesafire ziyanciphisa kakhulu izehlo zokufiphala kwelensi kutyando lwe-laparoscopic, nto leyo enciphisa ixesha lokusebenza. Umphezulu woqhagamshelwano ongagqunywanga uthintela ngokufanelekileyo ukunamathela kwe-mucosal kwizicelo ze-ENT endoscope.
• Iindleko Zokulungisa:Amaxabiso okulungisa ii-endoscopes zesafire ancitshiswa malunga nama-40%, nangona iindleko zokuqala zokuthenga ziphezulu.

.

2. Izikhokelo zoLungiselelo loBugcisa

• .Itekhnoloji yokuGcoba edityanisiweyo:Ukubeka i-AR engaphezulu kunye neengubo ezichasene ne-static kwicala elingadibaniyo ukuze kuncitshiswe ukunamathela kothuli.
• Ukucubungula iSapphire ngendlela engaqhelekanga:Ukwakha iifestile ezikhuselayo zesafire ezijijekileyo okanye ezigobileyo ukuze zilungele ii-endoscopes ezincinci ezinobubanzi obuqinileyo (< 2 mm).

Isiphelo​

I-Sapphire ibe yinto ephambili kwii-endoscopes eziqinileyo eziphezulu ngenxa yokulinganisela kwayo okugqibeleleyo kobulukhuni, ukhuseleko lwezinto eziphilayo, kunye nokusebenza kokukhanya. Uyilo lwengubo yecala elinye lusebenzisa iingubo zokuphucula ukusebenza kakuhle kokukhanya ngelixa lugcina ukhuseleko lwendalo lomphezulu woqhagamshelwano. Le ndlela ibonakalise ukuba sisisombululo esithembekileyo esihlangabezana neemfuno zeklinikhi. Njengoko iindleko zokucubungula i-sapphire ziyancipha, ukwamkelwa kwayo kwicandelo le-endoscopy kulindeleke ukuba kukhule ngakumbi, kuqhubele phambili izixhobo zotyando ezingangenisi kakhulu kukhuseleko olukhulu kunye nokuqina.
