Cov cuab yeej zoo nkauj Laser plaub hau tshem tawm tshuab

Lub hauv paus ntsiab lus ntawm kev zoo nkauj khoom diode laser plaub hau tshem tawm tshuab
Cov cuab yeej zoo nkauj diode laser plaub hau tshem tawm tshuab yog ib qho ntawm feem ntau siv cov cuab yeej tshem tawm plaub hau, nrog lub wavelength ntawm 800 txog 810 nm. Nws muaj kev nqus melanin nruab nrab thiab tuaj yeem nkag mus tob rau hauv cov hauv paus plaub hau, ua rau nws muaj kev nyab xeeb rau kev tshem tawm cov plaub hau hauv Fitzpatrick daim tawv nqaij hom II-V.
Hauv kev kho cov plaub hau tshem tawm, siv lub zog qis dua thiab lub sijhawm ntev ntawm kev ua haujlwm yog qhov zoo rau kev kho cua sov ntawm cov qia hlwb, ua tiav cov txiaj ntsig ntev. Tam sim ntawd tom qab siv lub zog txo qis, cov qauv ntawm cov epidermis thiab stratum corneum yog qhov qub, tab sis muaj qhov tseem ceeb edema nyob rau hauv cov txheej txheem ntawm cov dermis thiab cov plaub hau, qhia txog kev hloov ntawm cov qauv thiab inflammatory infiltration, tsim ntawm vacuoles nyob rau hauv cov plaub hau follicles, thiab cov txheej txheem ntawm cov plaub hau. Cov tsos ntawm alkaline clumps cuam tshuam rau degeneration. Lub polarity ntawm cov plaub hau follicle hlwb hloov, thiab cov qauv ntawm tes tsis yooj yim rau kev paub; Kev soj ntsuam ultrastructural nyob rau hauv electron microscopy kuj pom me ntsis edema ntawm cov plaub hau follicle hlwb, nrog rau qee qhov kev sib cais ntawm cov plaub hau follicle hlwb. Ib hlis tom qab, cov hauv paus plaub hau pom kev degeneration, manifested los ntawm immunohistochemical staining ntawm cov plaub hau follicle cell proliferating cell nuclear antigen PCNA (-), nrog tsuas yog ib feem p53 (+).
Tam sim no, semiconductor lasers feem ntau muab faib ua peb hom: ① siv lub taub hau kho qhov kub thiab zawv zawg hom (SHR, piv txwv li khov taw tes tshem tawm cov plaub hau); ② Tsis zoo siab nqus hom (lub teeb ntawv duo, piv txwv li lub tshuab nqus tsev tshem tawm); ③ Hom kev kho mob. Nyob rau hauv xyoo tas los no, vim yog kev txhim kho ntawm cov tshuab semiconductor, qhov sib txawv wavelengths ntawm semiconductor lasers tuaj yeem muab tso rau hauv ib qho khoom siv rau tib lub sijhawm tso tawm lasers, ua tiav cov txiaj ntsig ntawm kev kho cov hauv paus plaub hau nrog qhov sib txawv thiab qhov tob. Piv txwv li, integrating lasers nrog wavelengths ntawm 755 nm, 810 nm, thiab 1064 nm rau tib lub laser semiconductor thiab siv zawv zawg txoj kev kho. Rau cov tawv nqaij tsaus nti, laser wavelengths ntawm 810 nm, 940 nm, thiab 1064 nm yog kev koom ua ke rau kev kho mob stamping. Cov kev tshawb fawb cuam tshuam tau nyuam qhuav pib thiab xav tau kev kuaj mob ntxiv thiab kev tshawb fawb yooj yim.
