Ubwino Wogwiritsa Ntchito ndi Kuyika Kusanthula kwa Sapphire mu Rigid Endoscopes

Zamkatimu

1.Zapadera Zazida Zamtengo Wa safiro: Maziko a High-Performance Rigid Endoscopes

2.Innovative Single-Side Coating Technology: Kukwaniritsa Mulingo Wabwino Kwambiri Pakati pa Magwiridwe Owoneka ndi Chitetezo Chachipatala

3.Kukhazikika Kwambiri ndi Kuyika Makulidwe: Kuonetsetsa Kudalirika kwa Endoscope ndi Kusasinthika

4. Ubwino Wokwanira Pagalasi Yachikhalidwe Yowonekera: Chifukwa Sapphire Ndi Chosankha Chapamwamba

5.Kutsimikizika Kwachipatala ndi Chisinthiko Cham'tsogolo: Kuchokera pa Kuchita Bwino Kwambiri Kufikira Patsogolo la Technological Frontier

Sapphire (Al₂O₃), yokhala ndi kuuma kwa Mohs kwa 9 (yachiwiri kwa diamondi), kutsika kwamphamvu kwamafuta (5.3 × 10⁻⁶/K), komanso kusakhazikika kwachilengedwe, imakhala ndi mawonekedwe okhazikika akuthupi ndi makemikolo komanso mawonekedwe otulutsa kuwala kochuluka (0.15-5). Mothandizidwa ndi zinthu zabwinozi, safiro yatengedwa kwambiri m'zaka zaposachedwa popanga zida zowoneka bwino m'ma endoscopes olimba kwambiri, makamaka zotchingira mawindo oteteza kapena magalasi opangira magalasi.

Ine. Ubwino Wamtengo Wapatali wa Sapphire Monga Chida cha Ma Endoscopes Olimba

M'zinthu zachilengedwe, safiro imagwiritsidwa ntchito nthawi zambiri ngati gawo lalikulu la zinthu zowoneka bwino m'ma endoscopes olimba kwambiri, makamaka mawindo oteteza kapena magalasi acholinga. Kulimba kwake kopitilira muyeso komanso kukana kuvala kumachepetsa kwambiri chiwopsezo cha kukwapula kwapamtunda pokhudzana ndi minofu, kumateteza kuvulala kwa minofu chifukwa cha kuvala kwa lens, komanso kupirira kukangana kwanthawi yayitali kuchokera ku zida zopangira opaleshoni (mwachitsanzo, ma forceps, lumo), potero kumakulitsa moyo wautumiki wa endoscope.

safiro amawonetsa biocompatibility yabwino; ndi zinthu zopanda cytotoxic inert yomwe imakhala yosalala kwambiri (kukwaniritsa zovuta za Ra ≤ 0.5 nm pambuyo popukuta), zomwe zimachepetsa kumamatira kwa minofu ndi kuopsa kwa matenda pambuyo pa opaleshoni. Izi zimapangitsa kuti zigwirizane mosavuta ndi muyezo wa ISO 10993 wa biocompatibility wa chipangizo chachipatala. Kukaniza kwake kwapadera kwa kutentha kwakukulu ndi kupanikizika, chifukwa cha kuchepa kwa mphamvu yowonjezera kutentha (5.3 × 10⁻⁶ / K), kumapangitsa kuti apirire maulendo a 1000 a kutentha kwapakati pa 134 ° C popanda kusweka kapena kuwonongeka kwa ntchito.

Zowoneka bwino kwambiri zimapatsa miyala ya safiro yokhala ndi kufalikira kwakukulu (0.15-5.5 μm). Kutumiza kwake kumaposa 85% mu mawonekedwe a kuwala kowoneka bwino, kuonetsetsa kuwala kokwanira. Mlozera wapamwamba wa refractive (1.76 @ 589 nm) umathandizira kanjira kakang'ono ka ma lens curvature, kuwongolera kamangidwe kakang'ono ka ma endoscopes.

II. Coating Technology Design

Mu endoscopes olimba, zokutira za mbali imodzi (zomwe zimayikidwa kumbali yosalumikizana ndi minofu) pazigawo za safiro ndi kapangidwe katsopano kamene kamayendera magwiridwe antchito ndi chitetezo.

1. Optical Functional Optimization pa Coated Side

• Kupaka kwa Anti-Reflection (AR):Zoyikidwa pakatikati pa disolo (mbali yosalumikizana ndi minofu), zimachepetsa kunyezimira (kunyezimira kwa nkhope imodzi <0.2%), kumathandizira kufalikira kwa kuwala ndi kusiyanitsa kwazithunzi, kumapewa kulekerera kophatikizana ndi zokutira mbali ziwiri, komanso kumathandizira kuwongolera mawonekedwe.
• paKupaka kwa Hydrophobic/Anti-Fog:Imalepheretsa kusungunuka kwa lens yamkati mkati mwa opaleshoni, kusunga mawonekedwe omveka bwino.

2.Chitetezo Chofunika Kwambiri Pambali Yopanda Zopaka (Tissue Contact Side)

• Kutetezedwa kwa Zinthu Zachilengedwe za Sapphire:Imagwiritsira ntchito kusalala kwambiri komanso kukhazikika kwamankhwala pamtunda wa safiro, kupewa ngozi yopaka utoto chifukwa cholumikizana kwanthawi yayitali ndi minofu kapena mankhwala ophera tizilombo. Amathetsa mikangano yomwe ingakhalepo yokhudzana ndi zokutira (mwachitsanzo, ma oxide achitsulo) ndi minofu yamunthu.
• Njira Zothandizira Zosavuta:Mbali yosakutidwa imatha kulumikizana mwachindunji ndi mankhwala ophera tizilombo monga mowa ndi hydrogen peroxide popanda kukhudzidwa ndi kupaka dzimbiri.

III. Zizindikiro Zofunika Zaumisiri za Sapphire Component Processing and Coating

1. Zofunikira pa Sapphire Substrate Processing

• Kulondola kwa Geometric: Kulekerera kwa Diameter ≤ ± 0.01 mm (ma diameter wamba ang'onoang'ono olimba endoscopes ndi 3-5 mm).
• Flatness< λ/8 (λ = 632.8 nm), Eccentric Angle< 0.1°.
• Ubwino wa Pamwamba: Kukula kwa Ra ≤ 1 nm pamtunda wolumikizana ndi minofu kuti mupewe zingwe zazing'ono zomwe zimayambitsa kuwonongeka kwa minofu.

2.Single-Side Coating Process Standards

• Coating Adhesion: Imapambana mayeso odulidwa a ISO 2409 (Giredi 0, palibe peeling).
• Sterilization Resistance​: Pambuyo pa 1000 yotsekereza yotseketsa kwambiri, kusintha kowonekera kwa malo okutidwa ndi <0.1%.
• Mapangidwe Oyatira Ogwira Ntchito : Zotchingira zotsutsana ndi zowonera ziyenera kuphimba mtunda wa 400-900 nm wavelength, ndi transmittance single-surface> 99.5%.

IV. Kuwunika Kofananitsa ndi Zida Zopikisana (mwachitsanzo, Magalasi Owoneka)

Gome lotsatirali likufanizira zofunikira za safiro ndi galasi lakale la kuwala (monga BK7):

V. Clinical Feedback and Improvement Directions

1.Practical Application Feedback

• Kuwunika kwa Opaleshoni:Ma endoscope olimba a safiro amachepetsa kwambiri zochitika zowoneka bwino za lens mu opaleshoni ya laparoscopic, kufupikitsa nthawi ya opaleshoni. Kulumikizana kosatsekedwa kumalepheretsa kumamatira kwa mucosal mu ntchito za ENT endoscope.
• Mtengo Wokonza:Mitengo yokonza ma endoscopes a safiro imachepetsedwa ndi pafupifupi 40%, ngakhale ndalama zogulira zoyamba ndizokwera.

pa

2.Malangizo a Technical Optimization

• paComposite Coating Technology:Superimposing AR ndi zokutira zotsutsana ndi ma static kumbali yosalumikizana kuti muchepetse kumatira kwafumbi.
• Atypical Sapphire Processing:Kupanga mawindo oteteza a safiro opindika kapena opindika kuti agwirizane ndi ma endoscopes ang'onoang'ono olimba (<2 mm).

Pomaliza

Sapphire yakhala chinthu chofunikira kwambiri pama endoscopes olimba kwambiri chifukwa chakulimba kwake, kulimba kwachilengedwe, komanso magwiridwe antchito. Mapangidwe okutira a mbali imodzi amathandizira zokutira kuti apititse patsogolo kuwala kwinaku akuteteza chitetezo chachilengedwe cha malo olumikizana. Njirayi yatsimikizira kukhala yankho lodalirika pokwaniritsa zosowa zachipatala. Pamene mtengo wopangira safiro ukucheperachepera, kukhazikitsidwa kwake m'munda wa endoscopy kukuyembekezeka kukulirakulira, kuyendetsa zida zopangira maopaleshoni zomwe sizimasokoneza kwambiri kuti zikhale zotetezeka komanso zolimba.
