Lethathamo la Tse ka Hare

1. Thepa e Ikhethang ea Sesebelisuoa sa Sapphire: Motheo oa Li-Endoscopes tse sa Tletseng tsa Ts'ebetso e Phahameng

2.Innovative Single-Side Coating Technology: Ho Finyella Tekanyo e Ntle lipakeng tsa Ts'ebetso ea Optical le Ts'ireletso ea Clinical

3. Litlhaloso tse thata tsa Ts'ebetso le Koahelo: Ho netefatsa ho ts'epahala le ho ts'epahala ha Endoscope

4. Melemo e Felletseng ho Feta Khalase ea Tloaelo ea Optical: Hobaneng Sapphire e le Khetho ea Boemo bo Phahameng

5.Tlhahiso ea Bongaka le Tsoelo-pele ea Bokamoso: Ho Tloha ka Tšebeliso e sebetsang ho ea ho Technological Frontier

Sapphire (Al₂O₃), e thata ea Mohs ea 9 (ea bobeli ho daemane), coefficient e tlase ea katoloso ea mocheso (5.3 × 10⁻⁶/K), le ho se sebetse ka tlhaho, e na le litšobotsi tse tsitsitseng tsa 'mele le lik'hemik'hale hammoho le litšobotsi tsa phetiso ea khanya e pharaletseng (0.15-5). E tšehelitsoe ke thepa ena e ntle haholo, sapphire e amohetsoe haholo lilemong tsa morao tjena bakeng sa ho etsa likarolo tsa optical ka li-endoscope tse thata tse phahameng, haholo-holo likoahelo tsa lifensetere tse sireletsang kapa likopano tsa lense tse ikemiselitseng.

ke. Melemo ea mantlha ea Sapphire e le sesebelisoa sa li-endoscope tse thata

Lits'ebetsong tsa biomedical, safire e sebelisoa khafetsa joalo ka setsi sa mantlha sa likarolo tsa optical ho li-endoscope tse thata, haholo lifensetere tse sireletsang kapa lilense tsa sepheo. Ho thatafala ho hoholo ha eona le ho hanella ha eona ho fokotsa haholo kotsi ea mengopo nakong ea ho kopana le lisele, ho thibela ho phatloha ha lisele ka lebaka la ho roala ha lense, le ho mamella likhohlano tsa nako e telele tsa lisebelisoa tsa ho buoa (mohlala, li-forceps, lisekere), ka tsela eo, ho lelefatsa bophelo ba ts'ebeletso ea endoscope.

Sapphire e bonahatsa biocompatibility e babatsehang; ke ntho e se nang cytotoxic inert e nang le bokaholimo bo boreleli haholo (ho fihlela bokhopo ba Ra ≤ 0.5 nm ka mor'a ho belisoa), e leng ho fokotsang ho khomarela ha lisele le likotsi tsa tšoaetso ka mor'a ho sebetsa. Sena se etsa hore e lumellane habonolo le tekanyetso ea biocompatibility ea sesebelisoa sa bongaka sa ISO 10993. Ho hanyetsa ha eona ho ikhethang ho mocheso o phahameng le khatello, e bakoang ke coefficient e tlaase ea ho atolosa mocheso (5.3 × 10⁻⁶ / K), e lumella hore e mamelle ho feta 1000 ea potoloho e phahameng ea khatello ea mouoane ho 134 ° C ntle le ho senya kapa ho senyeha ha ts'ebetso.

Lintho tse ikhethang tsa optical li fa safire ka mefuta e mengata ea phetisetso (0.15–5.5 μm). Phetisetso ea eona e feta 85% maboneng a khanyang a bonahalang, e netefatsa khanya e lekaneng ea litšoantšo. The high refractive index (1.76 @ 589 nm) e thusa lense e nyenyane ea curvature radius, e nolofatsang moralo o monyenyane oa li-endoscope.

II. Coating Technology Design

Ho li-endoscope tse thata, ho roala ka lehlakoreng le le leng (hangata ho sebelisoa lehlakoreng le sa amaneng le lisele) likarolong tsa safire ke moralo o mocha o leka-lekaneng ts'ebetso le polokeho.

1. Optical Functional Optimization ka lehlakoreng le koahetsoeng

• Anti-Reflection (AR) Coating:E behiloe karolong e ka hare ea lense (lehlakore le sa amaneng le lisele), e fokotsa ho bonahatsa (ho bonahatsa sefahleho se le seng <0.2%), ho ntlafatsa phetisetso ea leseli le phapang ea setšoantšo, ho qoba ho mamellana ho tsoa ho ho roala ka mahlakoreng a mabeli, le ho nolofatsa tsamaiso ea optical system.
• .Hydrophobic/Anti-Fog Coating:E thibela condensation holim'a lense e ka hare nakong ea ho buuoa, ho boloka pono e hlakileng.

2.Bohlokoa ba Tšireletso ka Lehlakoreng le sa Koaheletsoeng (Lehlakoreng la Letlapa la Tissue)

• Paballo ea Lintho Tsa Tlhaho tsa Sapphire:E sebelisa boreleli bo phahameng ba tlhaho le botsitso ba lik'hemik'hale tsa bokaholimo ba safire, e qoba likotsi tsa ho phunya ka lebaka la ho kopana ha nako e telele le lisele kapa li-disinfectants. E felisa likhang tse ka bang teng tsa biocompatibility tse amanang le lisebelisoa tsa ho roala (mohlala, li-oxide tsa tšepe) le lisele tsa motho.
• Mekhoa e Nolofalitsoeng ea Tlhokomelo:Lehlakore le sa apesitsoeng le ka ikopanya ka kotloloho le li-disinfectants tse matla joalo ka joala le hydrogen peroxide ntle le ho ameha ka ho bola.

III. Lipontšo tsa Bohlokoa tsa Tekheniki bakeng sa Ts'ebetso ea Karolo ea Sapphire le ho Koaheloa

1. Litlhoko tsa ho sebetsa ka Sapphire Substrate

• Ho nepahala ha Jiometri: Mamello ea bophara ba ≤ ± 0.01 mm (li-diameter tse tloaelehileng bakeng sa li-endoscope tse thata tse nyane ke 3-5 mm).
• Flatness< λ/8 (λ = 632.8 nm), ​​Eccentric Angle < 0.1°.
• Boleng ba Bokahohle: Roughness Ra ≤ 1 nm holim'a sebaka se amanang le linama ho qoba likhopo tse nyane tse bakang tšenyo ea lisele.

2.Maemo a Ts'ebetso ea ho Koala ka Lehlakore le le leng

• Coating Adhesion: E fetisa tlhahlobo e fapaneng ea ISO 2409 (Kereiti ea 0, ha ho peeling).
• Sterilization Resistance​: Kamora 1000 high-pressure sterilization cycles, ponahatso ea sebaka se koahetsoeng ke <0.1%.
• Moralo o sebetsang oa Coating : Coat e thibelang ponahalo ea lintho e lokela ho koahela sebaka sa 400-900 nm wavelength, ka phetisetso ea sefahleho se le seng> 99.5%.

IV. Tlhahlobo e Bapisang le Lisebelisoa tsa Tlholisano (mohlala, Khalase ea Optical)

Tafole e latelang e bapisa thepa ea bohlokoa ea safire le khalase ea khale ea optical (joaloka BK7):

V. Clinical Feedback le Litaelo tsa Ntlafatso

1. Tšebeliso e sebetsang ea Feedback

• Tlhahlobo ea Ngaka:Li-endoscope tse thata tsa Sapphire li fokotsa haholo liketsahalo tsa ho fifala ha lense nakong ea opereishene ea laparoscopic, ho khutsufatsa nako ea ts'ebetso. Sebaka sa ho kopana se sa koahetsoeng se thibela ka katleho ho khomarela mucosal lits'ebetsong tsa ENT endoscope.
• Litšenyehelo tsa ho hlokomela:Litefiso tsa ho lokisa li-endoscope tsa safire li fokotsehile ka hoo e ka bang 40%, le hoja litšenyehelo tsa pele tsa ho reka li le holimo.

.

2. Litaelo tsa Ntlafatso ea Technical

• .Theknoloji ea Composite Coating:Superimposing AR le li-anti-static coatings ka lehlakoreng le sa amaneng le ho fokotsa lerōle.
• Mokhoa oa Atypical Sapphire:Ho hlahisa lifensetere tse sireletsang tsa safire tse betliloeng kapa tse kobehileng hore li ikamahanye le li-endoscopes tse thata tse bophara bo boholo (<2 mm).

Qetello

Sapphire e se e le sesebelisoa sa mantlha bakeng sa li-endoscope tse thata tsa maemo a holimo ka lebaka la ho leka-lekana ha eona ho thatafalang, biosafety, le ts'ebetso ea mahlo. Moralo oa ho roala ka lehlakore le le leng o phahamisa liphahlo ho ntlafatsa ts'ebetso ea optical ha o ntse o boloka polokeho ea sebaka sa ho ikopanya. Mokhoa ona o ipakile e le tharollo e tšepahalang e fihlelang litlhoko tsa bongaka. Ha litšenyehelo tsa ts'ebetso ea safire li ntse li fokotseha, ho amoheloa ha eona lebaleng la endoscopy ho lebelletsoe ho hola le ho feta, ho khanna lisebelisoa tse fokolang tsa ho buoa ho isa polokehong e kholo le ho tšoarella.
