Mesebetsi ea mantlha ea 980nm 1470nm Diode Laser

Tsa ronalaser ea diode 980nm + 1470nme ka tsamaisa leseli la laser ho lisele tse bonolo ka har'a mokhoa oa ho ikopanya le oa ho se kopane nakong ea opereishene. 980nmlaser ea sesebelisoa ka kakaretso e bontšoa bakeng sa tšebeliso ea ho cheka, ho phunya, mouoane, ho tlosa mali, ho ntša mali kapa ho kopanya lisele tse bonolo litsebeng, nko le 'metso le ho buuoa ka molomo (otolaryngology), mekhoa ea meno, gastroenterology, opereishene e akaretsang, dermatology, opereishene ea polasetiki, podiatry, urology. Sesebelisoa se boetse se bontšoa bakeng sa lipolysis e thusang laser. Laser ea 1470nm ea sesebelisoa e etselitsoe ho fana ka lisele tse bobebe tsa laser tosoft ka mokhoa o sa amaneng le batho nakong ea ts'ebetso ea opereishene e akaretsang, e bonts'itsoeng kalafo ea reflux ea methapo ea saphenous e amanang le methapo ea varicose le varicosities.

I. Mokhoa oa Dual-Wavelength System o Finyella Liphello tsa Tissue Joang?

Sesebelisoa se sebelisa photothermolysis e khethiloeng le ho kenngoa ha metsi ka tsela e fapaneng ho finyella mouoane, ho itšeha, ho ntša metsi le ho kopanya.

1. vaporization & Cutting

980nm:

E kenngoa ka mokhoa o itekanetseng ke metsi, e kenella ka botebo ba 3-5 mm.

Ho futhumatsa ka potlako (> 100 ° C) ho etsa hore ho be le mouoane oa lisele (ho belisa metsi a lisele).

Ka mokhoa o tsoelang pele / oa pulsed, o nolofalletsa ho itšeha (mohlala, lihlahala, lisele tsa hypertrophic).

1470nm:

Ho monya metsi a phahameng haholo (10× holimo ho 980nm), ho fokotsa botebo ho 0.5-2 mm.

E loketse bakeng sa ho itšeha ka mokhoa o nepahetseng (mohlala, opereishene ea mucosal) e nang le mocheso o fokolang oa mocheso.

2. Ablation & Coagulation

Mokhoa o Kopantsoeng:

980nm e etsa mouoane oa lisele → 1470nm seals likepe (collagen shrinkage ka 60-70 ° C).

E fokotsa ho tsoa mali lits'ebetsong tse kang ho ntša tšoelesa ea senya kapa opereishene ea laryngeal.

3. Mokhoa oa Hemostasis

1470nm:

Ka potlako e kopanya likepe tse nyane (<3 limilimithara) ka denaturation ea collagen le tšenyo ea endothelial.

II. 1470nm Wavelength bakeng sa Ho haella ha Venous & Varicose Veins

1. Mechanism of Action (Endovenous Laser Therapy, EVLT)

Sepheo:Metsi a leboteng la venous (ha a itšetlehe ka hemoglobin).

Tshebetso:

Ho kenngoa ha fiber ea laser: Ho kenngoa ka percutaneous ka har'a mothapo o moholo oa saphenous (GSV).

1470nm laser activation: Slow fiber pullback (1-2 mm / s).

Liphello tsa mocheso:

Ho senyeha ha endothelial → ho putlama ha methapo.

Collagen contraction → fibrosis e sa feleng.

2. Melemo Ho feta 980nm

Mathata a fokotsehileng (ho fokotseha ho fokolang, ho lemala ha methapo).

Litefiso tse phahameng tsa ho koala (> 95%, ho ea ka Journal of Vascular Surgery).

Matla a tlase a hlokahalang (ka lebaka la ho monya metsi ho phahameng).

III. Tšebeliso ea lisebelisoa

Phetoho ea Dual-Wavelength:

Khetho ea mokhoa oa letsoho/auto (mohlala, 980nm bakeng sa ho seha → 1470nm bakeng sa ho tiisa).

Fiber Optics:

Radial fibers (matla a tšoanang bakeng sa methapo).

Litlhahiso tsa ho ikopanya (bakeng sa likhetho tse nepahetseng).

Mekhoa ea ho Pholisa:

Pholiso ea moea / metsi ho thibela ho chesa ha letlalo.

IV. Qetello

980nm:Deep ablation, ka potlako resection.

1470nm:Coagulation e holimo, ho koaloa ha methapo.

Synergy:Li-wavelengths tse kopantsoeng li etsa hore "cut-and-seal" e sebetse hantle ha ho buuoa.

Bakeng sa lisebelisoa tse khethehileng kapa lithuto tsa bongaka, fana ka ts'ebeliso e reriloeng (mohlala, urology, phlebology).
