Sapphire (Al₂O₃), nrog Mohs hardness ntawm 9 (thib ob nkaus xwb rau pob zeb diamond), tsis tshua muaj coefficient ntawm thermal expansion (5.3 × 10⁻⁶ / K), thiab inertness inertness, muaj ib tug ruaj khov heev lub cev thiab tshuaj zog nrog rau broad-spectrum lub teeb kis tau tus mob (0.15-5.5 μm). Kev txhawb nqa los ntawm cov khoom zoo heev no, sapphire tau siv dav hauv xyoo tas los no rau kev tsim cov khoom siv kho qhov muag hauv high-end rigid endoscopes, tshwj xeeb tshaj yog kev tiv thaiv qhov rais npog lossis lub hom phiaj lens sib dhos.

kuv. Cov txiaj ntsig tseem ceeb ntawm Sapphire ua cov khoom siv rau Rigid Endoscopes

Hauv kev siv biomedical, sapphire feem ntau yog siv los ua thawj lub substrate rau cov khoom siv kho qhov muag hauv high-end rigid endoscopes, tshwj xeeb tshaj yog rau cov qhov rais tiv thaiv lossis lub hom phiaj lo ntsiab muag. Nws cov hardness ultra-siab thiab hnav tsis kam txo qhov kev pheej hmoo ntawm kev khawb ntawm qhov chaw thaum sib cuag nrog cov ntaub so ntswg, tiv thaiv cov ntaub so ntswg puas los ntawm lub lens hnav, thiab tiv taus kev sib txhuam mus ntev los ntawm cov cuab yeej phais (xws li, forceps, txiab), yog li ncua lub endoscope lub neej kev pab cuam.

Sapphire nthuav tawm biocompatibility zoo heev; Nws yog cov khoom siv tsis-cytotoxic inert nrog lub ntsej muag zoo heev (ua tiav qhov ntxhib ntawm Ra ≤ 0.5 nm tom qab polishing), uas txo cov ntaub so ntswg adhesion thiab kev pheej hmoo kis mob tom qab phais. Qhov no ua rau nws yooj yim ua raws li ISO 10993 cov cuab yeej kho mob biocompatibility tus qauv. Nws qhov tshwj xeeb tsis kam mus rau qhov kub thiab txias, vim tias qhov sib txawv ntawm thermal expansion (5.3 × 10⁻⁶ / K), tso cai rau nws mus dhau 1000 cycles ntawm high-pressure steam sterilization ntawm 134 ° C yam tsis muaj cracking lossis kev ua haujlwm degradation.

Cov khoom siv kho qhov muag zoo kawg nkaus ua rau sapphire nrog kev sib kis dav dav (0.15-5.5 μm). Nws transmittance tshaj 85% nyob rau hauv lub pom lub teeb spectrum, kom ntseeg tau txaus imaging brightness. Lub siab refractive Performance index (1.76 @ 589 nm) ua rau lub lens me me curvature vojvoog, ua rau lub miniaturized tsim ntawm endoscopes.

II. Txheej Technology Design

Nyob rau hauv nruj endoscopes, ib-sab txheej txheej (feem ntau yog siv rau sab tsis hu rau cov ntaub so ntswg) ntawm sapphire Cheebtsam yog ib qho kev tsim tshiab uas sib npaug kev ua tau zoo thiab kev nyab xeeb.

1.Optical Functional Optimization ntawm Coated Sab

• Anti-Reflection (AR) Txheej:Muab tso rau ntawm qhov chaw sab hauv ntawm lub lens (tsis yog cov ntaub so ntswg sab), nws txo qhov kev xav tau (ib qho chaw pom kev pom <0.2%), txhim kho lub teeb pom kev zoo thiab cov duab zoo sib xws, zam kev ua kom ntev ntev los ntawm ob txheej txheej, thiab ua kom yooj yim kho qhov muag.
• uaHydrophobic / Anti-Fog Txheej:Tiv thaiv condensation ntawm lub ntsej muag sab hauv lub ntsej muag thaum phais, tswj xyuas qhov pom tseeb.

2.Safety Priority on the Non-Coated Side (Tissue Contact Side) ​​

• Kev khaws cia ntawm Sapphire's Inherent Properties:Siv cov haiv neeg siab smoothness thiab tshuaj stability ntawm sapphire nto, tsis txhob muaj kev pheej hmoo ntawm txheej tev vim mus ntev kev sib cuag nrog cov ntaub so ntswg los yog tshuaj tua kab mob. Tshem tawm qhov muaj peev xwm biocompatibility controversies txuam nrog cov ntaub ntawv txheej (xws li, hlau oxides) thiab tib neeg cov ntaub so ntswg.
• Simplified Maintenance Procedures:Sab tsis-coated tuaj yeem hu ncaj qha rau cov tshuaj tua kab mob zoo li cawv thiab hydrogen peroxide yam tsis muaj kev txhawj xeeb rau txheej txheej corrosion.

III ib. Cov Lus Qhia Tseem Ceeb rau Sapphire Component Processing thiab Txheej

1.Sapphire Substrate Processing Requirements

• Geometric Accuracy ​​: Txoj kab uas hla kam rau ua ≤ ± 0.01 hli (qhov dav dav rau cov khoom me me tsis zoo yog 3-5 hli).
• Flatness < λ/8 (λ = 632.8 nm), ​​Eccentric Angle < 0.1°.
• Surface Quality ​​: Roughness Ra ≤ 1 nm ntawm cov ntaub so ntswg tiv thaiv kom tsis txhob muaj cov khawb ua rau cov ntaub so ntswg puas.

2.Single-Side Txheej Txheej Txheej Txheem

• Txheej Adhesion ​​: Dhau ISO 2409 hla kev xeem (Qib 0, tsis muaj tev).
• Sterilization Resistance ​​: Tom qab 1000 lub voj voog ua kom tsis muaj zog, qhov kev hloov pauv ntawm cov coated nto yog <0.1%.
• ​​Functional Coating Design ​​: Anti-reflection txheej yuav tsum npog 400-900 nm wavelength ntau yam, nrog ib qho chaw xa tawm> 99.5%.

IV ib. Kev sib piv nrog cov khoom sib tw (xws li, Kho qhov muag iav).

Cov lus hauv qab no piv cov khoom tseem ceeb ntawm sapphire thiab cov iav kho qhov muag (xws li BK7):

V. Clinical Feedback and Improvement Directions

1.Practical Application Feedback

• Kev ntsuam xyuas kws phais:Sapphire rigid endoscopes txo qis qhov pom qhov muag pom qhov tshwm sim hauv kev phais laparoscopic, ua kom lub sijhawm ua haujlwm luv. Lub ntsej muag tsis sib txuas zoo tiv thaiv mucosal adhesion hauv ENT endoscope daim ntawv thov.
• Tus nqi kho mob:Kev kho tus nqi rau sapphire endoscopes raug txo los ntawm kwv yees li 40%, txawm hais tias thawj tus nqi yuav khoom yog siab.

ua

2.Technical Optimization Directions

• uaComposite Txheej Technology:Superimposing AR thiab anti-static coatings ntawm sab tsis sib cuag los txo cov plua plav adhesion.
• Atypical Sapphire Txheej Txheem:Txhim kho beveled los yog nkhaus sapphire tiv thaiv qhov rais kom hloov mus rau me me txoj kab uas hla nruj endoscopes (< 2 hli).

Xaus

Sapphire tau dhau los ua cov khoom tseem ceeb rau high-end rigid endoscopes vim nws qhov zoo sib npaug ntawm hardness, biosafety, thiab optical kev ua tau zoo. Cov txheej txheej ib sab tsim leverages coatings los txhim kho qhov muag pom kev zoo thaum khaws cia cov neeg muaj kev nyab xeeb ntawm kev sib cuag. Txoj hauv kev no tau ua pov thawj tias yog qhov kev daws teeb meem txhim khu kev qha raws li kev xav tau kho mob. Raws li cov nqi ua sapphire txo qis, nws txoj kev saws me nyuam hauv qhov chaw endoscopy yuav tsum loj hlob ntxiv, tsav tsheb cov cuab yeej phais me me mus rau kev nyab xeeb dua thiab ua haujlwm ntev.
