Okwethui-diode laser 980nm+1470nmUkulethwa kokukhanya kwe-laser ezicutshini ezithambile ngendlela yokuxhumana kanye nemodi yokungathintani ngesikhathi sokuhlinzwa. I-980nmlaser yedivayisi ngokuvamile ikhonjiswa ukusetshenziswa ekusikeni, ekususeni, ekushiseni, ekususeni izicubu ezithambile endlebeni, ekhaleni nasemphinjeni kanye nasekuhlinzeni ngomlomo (otolaryngology), izinqubo zamazinyo, i-gastroenterology, ukuhlinzwa okujwayelekile, i-dermatology, ukuhlinzwa kwepulasitiki, i-podiatry, i-urology, i-gynecology. Idivayisi ikhonjiswa futhi nge-laser assisted lipolysis. I-laser yedivayisi engu-1470nm ihloselwe ukulethwa kokukhanya kwe-laser ezicutshini ezithambile ngendlela yokungathintani ngesikhathi sezinqubo zokuhlinzwa ezijwayelekile, ikhonjiswa ekwelapheni i-reflux yemithambo ye-saphenous ehlotshaniswa nemithambo ye-varicose kanye ne-varicosities.
I. Uhlelo Lobude Obuphindwe Kabili Luyifinyelela Kanjani Imiphumela Yezicubu?
Le divayisi isebenzisa i-photothermolysis ekhethiwe kanye nokumuncwa kwamanzi okuhlukile ukuze kufezwe ukuhwamuka, ukusika, ukususwa, kanye nokujiya.
| Ubude begagasi | I-Chromophore Eyinhloko | Ukusebenzisana Kwezicubu | Izicelo Zemitholampilo |
| 980nm | Amanzi + i-Hemoglobin | Ukungena okujulile, ukuhwamuka/ukusika okunamandla | Ukususwa, ukususwa kwesisu, ukususwa kwegazi |
| 1470nm | Amanzi (ukumuncwa okuphezulu) | Ukushisa okungaphandle, ukujiya okusheshayo | Ukuvalwa kwemithambo, ukusika ngokunemba |
1. Ukushiswa Nokunqunywa Kwezinto Ezingashisi
980nm:
Uma umuncwa ngamanzi ngokulingene, ungena ujule ngamamilimitha angu-3-5.
Ukushisa okusheshayo (>100°C) kubangela ukuhwamuka kwezicubu (ukubila kwamanzi eseli).
Kwimodi eqhubekayo/eqhutshwayo, ivumela ukusika kokuthintana (isb., izimila, izicubu ezinamafutha amaningi).
1470nm:
Ukumuncwa kwamanzi okuphezulu kakhulu (10× okuphakeme kuno-980nm), okunciphisa ukujula kube ngu-0.5–2 mm.
Kuhle kakhulu ekusikeni ngokunembile (isb., ukuhlinzwa kwe-mucosal) ngokusabalala okuncane kokushisa.
2. Ukususwa Nokujiya Kwegazi
Imodi Ehlanganisiwe:
I-980nm ishintsha izicubu zibe ngumhwamuko → I-1470nm ivala imithambo yegazi (i-collagen incipha ku-60–70°C).
Kunciphisa ukopha ezinqubweni ezifana nokukhipha i-prostate noma ukuhlinzwa kwe-laryngeal.
3. Indlela Yokumisa Igazi
1470nm:
Ijiya ngokushesha imithambo emincane (<3 mm) ngokushintshashintsha kwe-collagen kanye nomonakalo we-endothelial.
II. Ubude be-Wavelength obungu-1470nm bokungakwazi ukukhiqiza imithambo yegazi kanye nemithambo ye-varicose
1. Indlela Yokusebenza (Ukwelashwa Nge-Laser Endovenous, EVLT)
Inhloso:Amanzi odongeni lwemithambo yegazi (awaxhomekile ku-hemoglobin).
Inqubo:
Ukufakwa kwe-laser fiber: Ukufakwa kwe-percutaneous emthanjeni omkhulu we-saphenous (GSV).
Ukusebenza kwe-laser okungu-1470nm: Ukudonswa kwe-fiber okuhamba kancane (1–2 mm/s).
Imiphumela yokushisa:
Ukubhujiswa kwe-endothelial → ukudilika kwemithambo yegazi.
Ukufinyela kwe-collagen → i-fibrosis engapheli.
2. Izinzuzo Ezingaphezu Kuka-980nm
Izinkinga ezincishisiwe (ukulimala okuncane, ukulimala kwemizwa).
Amanani aphezulu okuvalwa (>95%, ngokwe-Journal of Vascular Surgery).
Kudingeka amandla aphansi (ngenxa yokumuncwa kwamanzi okuphezulu).
III. Ukusetshenziswa Kwedivayisi
Ukushintsha Ubude Begagasi Eliphindwe Kabili:
Ukukhetha imodi ezenzakalelayo/eyenziwe ngesandla (isb., 980nm yokusika → 1470nm yokuvala).
I-Fiber Optics:
Imicu yemisebe (amandla afanayo emithanjeni).
Amathiphu okuxhumana (ukuze uthole ukusikwa okunembile).
Izinhlelo Zokupholisa:
Ukupholisa umoya/amanzi ukuvimbela ukusha kwesikhumba.
IV. Isiphetho
980nm:Ukususwa okujulile, ukususwa okusheshayo.
1470nm:Ukujiya okungabonakali, ukuvalwa kwemithambo yegazi.
Ukusebenzisana:Ama-wavelength ahlanganisiwe avumela ukusebenza kahle "kokusika nokuvala" ekuhlinzeni.
Ngemingcele ethile yedivayisi noma izifundo zemitholampilo, nikeza uhlelo oluhlosiwe (isb., i-urology, i-phlebology).
