ISapphire (i-Al₂O₃), enobulukhuni be-Mohs ye-9 (yesibini kuphela ukuya kwidayimane), i-coefficient ephantsi yokwandiswa kwe-thermal (5.3×10⁻⁶/K), kunye nokungazenzisi okungokwemvelo, ineempawu ezizinzileyo zomzimba kunye neekhemikhali kunye neempawu zokuhambisa ukukhanya okubanzi (0.15-5). Ixhaswe zezi zakhiwo zibalaseleyo, isafire yamkelwe ngokubanzi kwiminyaka yamva nje ukwenza izinto ezibonakalayo kwii-endoscopes eziqinileyo zokugqibela, ngakumbi izigqubuthelo zefestile ezikhuselayo okanye iindibano zelensi ezinenjongo.

I. Izinto eziluncedo ezingundoqo zeSapphire njengesixhobo se-Endoscopes eRigid

Kwizicelo ze-biomedical, i-sapphire isetyenziswa rhoqo njenge-substrate ephambili yamacandelo e-optical kwi-endoscopes eqinile, ngokukodwa kwiifestile ezikhuselayo okanye iilensi ezinenjongo. Ubunzima bayo obuphezulu kakhulu kunye nokumelana nokunxiba kunciphisa kakhulu umngcipheko wokukrweleka komphezulu ngexesha lokudibana nethishu, kuthintela ukukrala kwezicubu okubangelwa kukunxitywa kwelensi, kunye nokumelana nokukhuhlana kwexesha elide kwizixhobo zotyando (umz., iiforceps, izikere), ngaloo ndlela ukwandisa ubomi benkonzo ye-endoscope.

ISapphire ibonisa ukuhambelana kwezinto eziphilayo; yinto ye-inert engekho ye-cytotoxic ene-surface ephezulu kakhulu (ukufikelela kwi-roughness ye-Ra ≤ 0.5 nm emva kokupholisa), okunciphisa ukunamathela kwezicubu kunye neengozi zokusuleleka emva kokuhlinzwa. Oku kuyenza ihambelane ngokulula nomgangatho we-ISO 10993 wesixhobo sonyango sokuhambelana nebhayoloji. Ukuchasana kwayo okuyingqayizivele kwiqondo lokushisa eliphezulu kunye noxinzelelo, olubangelwa i-coefficient ephantsi yokwandiswa kwe-thermal (5.3 × 10⁻⁶ / K), ivumela ukuba ikwazi ukunyamezela imijikelezo ye-1000 ye-high-pressure sterilization ye-sterilization kwi-134 ° C ngaphandle kokuqhekeka okanye ukuthotywa kokusebenza.

Iimpawu ezibalaseleyo zamehlo zinika isafire ngoluhlu olubanzi losulelo (0.15–5.5 μm). Ukuhanjiswa kwayo kudlula i-85% kwi-spectrum yokukhanya ebonakalayo, iqinisekisa ukukhanya okwaneleyo kwemifanekiso. Isalathisi esiphezulu se-refractive (1.76 @ 589 nm) senza i-lens curvature radius encinci, iququzelele uyilo oluncinci lwe-endoscopes.

II. Uyilo lweTekhnoloji yoCoating

Kwii-endoscopes eziqinileyo, i-coating-side-side coating (edla ngokusetyenziswa kwicala elingaqhagamshelani nezicubu) kumalungu esafire luyilo olutsha olulinganisa ukusebenza kunye nokhuseleko.

1.UkuSebenza okuSebenzayo ngokuSebenzayo kwiCala eliNgqunyiweyo

• I-Anti-Reflection (AR) Coating:I-Deposit kwi-surface yangaphakathi ye-lens (i-non-tissue contact side), iyanciphisa i-reflection (i-reflection ye-single-surface <0.2%), iphucula ukuhanjiswa kokukhanya kunye nokuchasana komfanekiso, igweme ukunyamezela okuqokelelweyo kwi-coating-side-side, kunye nokwenza lula ukulinganisa inkqubo ye-optical system.
• .I-Hydrophobic/Anti-Fog Coating:Ikhusela ukuxinana kwi-lens yangaphakathi ebusweni ngexesha lotyando, ukugcina intsimi ecacileyo yokujonga.

2.Ukhuseleko oluPhambili kwiCala eliNgagqunywanga (Icala loQhagamshelwano lweTissue)​

• Ugcino lweePropathi zeSapphire zeNdalo:Isebenzisa ubumpuluswa obuphezulu bemveli kunye nokuzinza kweekhemikhali zomphezulu wesafire, ukuthintela umngcipheko wokuxobuka ngenxa yokunxibelelana kwexesha elide kunye nezicubu okanye izibulala-ntsholongwane. Ukuphelisa iingxabano ezinokuthi zenzeke kwi-biocompatibility ezinxulumene nezixhobo zokugquma (umzekelo, ii-oxide zetsimbi) kunye nezicubu zomntu.
• Iinkqubo zoLondolozo eziLula:Icala elingagqunywanga linokuqhagamshelana ngokuthe ngqo nezibulali ntsholongwane ezinamandla njengotywala kunye nehydrogen peroxide ngaphandle kokuxhalabela ukubola.

III. Iimpawu eziphambili zobuGcisa zeSapphire Component Processing and Coating

1. IiMfuno zokuLungisa iSapphire Substrate

• Ukuchaneka kweJiyometri​: Ukunyamezelana kweDiameter ≤ ±0.01 mm (iidayamitha eziqhelekileyo kwii-endoscopes ezincinci eziqinileyo ziyi-3–5 mm).
• Ukuthe tyaba​ < λ/8 (λ = 632.8 nm), i-Eccentric Angle < 0.1°.
• Umgangatho oMphezulu: Uburhabaxa Ra ≤ 1 nm kumphezulu wokudibana kwethishu ukunqanda imikrwelo emincinci ebangela umonakalo kwithishu.

2.ImiGangatho yeNkqubo yokuNgquma ngecala elinye

• I-Coating Adhesion: Uphumelele uvavanyo lwe-ISO 2409 olunqamlezayo (iBakala 0, akukho kuxobula).
• I-Sterilization Resistance​: Emva kwemijikelo ye-1000 yoxinzelelo oluphezulu lokuvala inzala, imbonakalo yokutshintsha komphezulu ogqunyiweyo yi-<0.1%.
• Uyilo oluSebenzayo loKutyabeka: I-anti-reflection kufuneka igqume i-400-900 nm yavelength uluhlu, kunye nokuhanjiswa komphezulu omnye> 99.5%.

IV. Uhlalutyo lokuthelekisa kunye neZixhobo zoKhuphiswano (umzekelo, i-Optical Glass)

Le theyibhile ilandelayo ithelekisa iipropati eziphambili zesafire kunye neglasi yendalo yamehlo (njenge-BK7):

V. Impendulo yeklinikhi kunye neMikhombandlela yoPhuculo

1.Impendulo yeSicelo esiSebenzayo

• UVavanyo lukaGqirha:Ii-endoscopes eziqinileyo zeSapphire zinciphisa kakhulu iziganeko zokufiphalisa iilensi kutyando lwe-laparoscopic, ukunciphisa ixesha lokusebenza. Umphezulu woqhagamshelwano ongenanto ukhusela ngokufanelekileyo ukunamathela kwe-mucosal kwizicelo ze-ENT endoscope.
• Iindleko zokulungisa:Amazinga okulungisa ii-endoscopes zesafire athotywa malunga ne-40%, nangona iindleko zokuqala zokuthenga ziphezulu.

.

2. Izalathiso zokuSebenza ngoBuchule

• .Itekhnoloji yoKugquma iTekhnoloji:Ukugqithisa i-AR kunye neengubo ezichasene ne-static kwicala elingadibanisiyo ukunciphisa ukunamathela kothuli.
• Ukwenziwa kweSapphire eAtypical:Ukuphuhlisa i-beveled okanye i-curved i-sapphire iifestile ezikhuselayo ukuze zilungelelanise i-endoscopes encinci ye-diameter eqinile (<2 mm).

Ukuqukumbela

I-Sapphire iye yaba yinto ephambili ye-endoscopes eqinile kwisiphelo esiphezulu ngenxa yokulinganisela kwayo okugqibeleleyo kobunzima, i-biosafety, kunye nokusebenza kwamehlo. Uyilo lwecala elinye lokugquma luphakamisa ii-coatings ukunyusa ukusebenza kakuhle kwamehlo ngelixa ugcina ukhuseleko lwasekhaya lomphezulu woqhagamshelwano. Le ndlela ibonakalise ukuba sisisombululo esithembekileyo esihlangabezana neemfuno zeklinikhi. Njengoko iindleko zokusetyenzwa kwesafire zisehla, ukwamkelwa kwayo kwindawo ye-endoscopy kulindeleke ukuba ikhule ngakumbi, iqhuba izixhobo zotyando ezihlaselayo zisingise kukhuseleko olukhulu kunye nokuqina.
