Ubwino Wogwiritsira Ntchito ndi Kusanthula Kwa Sapphire Pophimba mu Endoscopes Yolimba​

Zamkatimu

1. Katundu Wapadera wa Sapphire Material: Maziko a High-Performance Rigid Endoscopes​

2. Ukadaulo Watsopano Wopaka Mbali Imodzi: Kupeza Kulinganiza Kwabwino Pakati pa Kugwira Ntchito Kwa Maso ndi Chitetezo Chachipatala​

3. Zofunikira pa Kukonza ndi Kuphimba: Kuonetsetsa Kuti Endoscope Ndi Yodalirika komanso Yogwirizana​

4. Ubwino Wambiri Poyerekeza ndi Galasi Lachikhalidwe Lowala: Chifukwa Chake Sapphire Ndi Chosankha Chapamwamba​

5. Kutsimikizika kwa Zachipatala ndi Kusintha kwa Mtsogolo: Kuchokera pa Kugwira Ntchito Moyenera Kupita ku Malire a Ukadaulo​

Sapphire (Al₂O₃), yokhala ndi kuuma kwa Mohs kwa 9 (yachiwiri pambuyo pa diamondi), coefficient yochepa ya kutentha (5.3×10⁻⁶/K), komanso kusakhala ndi mphamvu, ili ndi mphamvu zokhazikika komanso zamakemikolo pamodzi ndi mphamvu zotumizira kuwala kwa ma spectrum ambiri (0.15–5.5 μm). Mothandizidwa ndi mphamvu zabwinozi, safiro yagwiritsidwa ntchito kwambiri m'zaka zaposachedwa popanga zinthu zowunikira mu ma endoscope olimba kwambiri, makamaka zophimba mawindo zoteteza kapena ma assemblies a lens objective.

I. Ubwino Waukulu wa Sapphire Monga Chinthu Chogwiritsira Ntchito Ma Endoscope Olimba

Mu ntchito zachipatala, safiro nthawi zambiri imagwiritsidwa ntchito ngati chinthu chachikulu chomwe chimagwiritsidwa ntchito popanga zinthu zowunikira mu ma endoscope olimba kwambiri, makamaka pa mawindo oteteza kapena magalasi ofunikira. Kulimba kwake kwakukulu komanso kukana kukalamba kumachepetsa kwambiri chiopsezo cha kukanda pamwamba pakakhudzana ndi minofu, kumaletsa kusweka kwa minofu chifukwa cha kuwonongeka kwa lenzi, komanso kupirira kukangana kwa nthawi yayitali kuchokera ku zida zopangira opaleshoni (monga forceps, lumo), motero kumawonjezera nthawi ya ntchito ya endoscope.

Safira imagwirizana bwino kwambiri ndi zinthu zachilengedwe; ndi chinthu chopanda poizoni chomwe chili ndi malo osalala kwambiri (chomwe chimapangitsa kuti Ra ≤ 0.5 nm ikamapukutidwa), zomwe zimachepetsa kumamatira kwa minofu ndi zoopsa za matenda pambuyo pa opaleshoni. Izi zimapangitsa kuti ikhale yogwirizana mosavuta ndi muyezo wa ISO 10993 wa zida zamankhwala. Kukana kwake kwapadera kutentha ndi kupanikizika, komwe kumachitika chifukwa cha kuchuluka kochepa kwa kutentha (5.3×10⁻⁶/K), kumalola kuti ipirire ma cycle opitilira 1000 a steam-pressure sterilization pa 134°C popanda kusweka kapena kuwonongeka kwa magwiridwe antchito.

Kapangidwe kake ka kuwala kamapereka safiro yokhala ndi ma transmission osiyanasiyana (0.15–5.5 μm). Kutumiza kwake kumaposa 85% mu spectrum yowoneka bwino, zomwe zimapangitsa kuti zithunzi ziwoneke bwino. Chizindikiro cha refractive index (1.76 @ 589 nm) chimalola kuti lens curvature radius yaying'ono iwoneke bwino, zomwe zimathandiza kuti ma endoscopes apangidwe pang'ono.

II. Kapangidwe ka Ukadaulo Wopaka​

Mu ma endoscope olimba, chophimba cha mbali imodzi (chomwe nthawi zambiri chimayikidwa kumbali yosakhudza minofu) pa zinthu za safiro ndi kapangidwe katsopano komwe kamagwirizanitsa magwiridwe antchito ndi chitetezo.

1. Kukonza Kogwira Ntchito Kowoneka Bwino Mbali Yophimbidwa​

• Chophimba Chotsutsa Kuwunikira (AR):Ikayikidwa mkati mwa lenzi (mbali yosakhudzana ndi minofu), imachepetsa kuwunikira (kuwunikira kwa pamwamba pa chinthu chimodzi < 0.2%), imawonjezera kufalikira kwa kuwala ndi kusiyana kwa chithunzi, imapewa kulekerera kophatikizana kuchokera ku utoto wa mbali ziwiri, ndipo imachepetsa kuwerengera kwa makina owonera.
• paChophimba Chopanda Nkhungu/Chopanda Nkhungu​​:Zimaletsa kuuma kwa mandala mkati mwa lenzi panthawi ya opaleshoni, zomwe zimapangitsa kuti malo owonekera bwino azitha kuonekera bwino.

2. Chitetezo Chofunika Kwambiri Mbali Yopanda Chophimba (Mbali Yolumikizana ndi Tishu)​

• Kusunga Zinthu Zachilengedwe za Sapphire:Amagwiritsa ntchito kusalala kwachilengedwe komanso kukhazikika kwa mankhwala pamwamba pa safiro, kupewa zoopsa zochotsa utoto chifukwa cha kukhudzana kwa nthawi yayitali ndi minofu kapena mankhwala ophera tizilombo. Amathetsa mikangano yomwe ingakhalepo chifukwa cha zinthu zophimba (monga zitsulo zosungunuka) ndi minofu ya anthu.
• Njira Zosavuta Zokonzera​​:Mbali yosakutidwa ndi utoto imatha kukhudzana mwachindunji ndi mankhwala amphamvu ophera tizilombo toyambitsa matenda monga mowa ndi hydrogen peroxide popanda kuda nkhawa ndi dzimbiri la utoto.

​​III. Zizindikiro Zaukadaulo Zofunikira pa Kukonza ndi Kuphimba kwa Sapphire Component

1. Zofunikira pa Kukonza Substrate ya Sapphire​​

• Kulondola kwa Jiyometri​: Kulekerera kwa m'mimba mwake ≤ ± 0.01 mm (ma diameter wamba a ma endoscope ang'onoang'ono olimba ndi 3–5 mm).
• Flatness< λ/8 (λ = 632.8 nm), Eccentric Angle< 0.1°.
• Ubwino wa Pamwamba​​: Kukwawa kwa Ra ≤ 1 nm pamwamba pa minofu kuti tipewe kukanda pang'ono komwe kungayambitse kuwonongeka kwa minofu.

2. Miyezo Yopangira Zophimba Mbali Imodzi​​

• Kumatira Kophimba​: Kupambana mayeso odulidwa a ISO 2409 (Giredi 0, palibe kuchotsedwa).
• Kukana Kuyeretsa: Pambuyo pa maulendo 1000 oyeretsa kwambiri, kusintha kwa mawonekedwe a pamwamba pake ndi < 0.1%.
• Kapangidwe ka Kuphimba Kogwira Ntchito​: Kuphimba kotsutsana ndi kuwunikira kuyenera kuphimba kutalika kwa mafunde a 400–900 nm, ndi transmittance ya pamwamba imodzi > 99.5%.

IV. Kusanthula Koyerekeza ndi Zipangizo Zopikisana (monga, Galasi Lowoneka)​

Tebulo lotsatirali likuyerekeza makhalidwe ofunikira a safiro ndi galasi lachikhalidwe (monga BK7):

V. Malangizo a Zachipatala ndi Malangizo Othandizira

1. Ndemanga Yothandiza Yogwiritsira Ntchito​

• Kuwunika kwa Opaleshoni:Ma endoscope olimba a safiro amachepetsa kwambiri kusokonekera kwa ma lens mu opaleshoni ya laparoscopic, zomwe zimapangitsa kuti nthawi yogwira ntchito ichepe. Malo olumikizirana osaphimbidwa bwino amaletsa kumatirira kwa mucosal mu ntchito za ENT endoscope.
• Mtengo Wokonza:Mitengo yokonza ma endoscope a safiro imachepetsedwa ndi pafupifupi 40%, ngakhale kuti ndalama zogulira zoyambirira zimakhala zokwera.

pa

2. Malangizo Okonza Zaukadaulo​​

• paUkadaulo Wopangira Zophimba Zophatikiza:Kuyika zophimba za AR ndi anti-static kumbali yosakhudzana kuti muchepetse kuuma kwa fumbi.
• Kukonza Sapphire Kosazolowereka:Kupanga mawindo oteteza a safiro okhala ndi mipata kapena opindika kuti agwirizane ndi ma endoscope ang'onoang'ono okhwima m'mimba mwake (< 2 mm).

Mapeto​

Safira wakhala chinthu chofunikira kwambiri pa ma endoscope olimba kwambiri chifukwa cha kulimba kwake, chitetezo cha chilengedwe, komanso magwiridwe antchito a kuwala. Kapangidwe kake ka mbali imodzi kamagwiritsa ntchito zokutira kuti ziwonjezere magwiridwe antchito a kuwala ndikusunga chitetezo cha malo olumikizirana. Njirayi yatsimikizira kuti ndi yankho lodalirika lomwe likukwaniritsa zosowa zachipatala. Pamene ndalama zokonzera safiro zikuchepa, kugwiritsa ntchito kwake m'munda wa endoscopy kukuyembekezeka kukula kwambiri, zomwe zimapangitsa kuti zida zochitira opaleshoni zisalowerere kwambiri kuti zikhale zotetezeka komanso zolimba.
