I. Bawo ni Eto Meji-Wefulenti Ṣe Ṣe aṣeyọri Awọn ipa Tissue?

Ẹrọ naa nlo photothermolysis ti o yan ati gbigba omi iyatọ lati ṣaṣeyọri vaporization, gige, ablation, ati coagulation.

1. Vaporization & Ige

980nm:

Niwọntunwọnsi ti o gba nipasẹ omi, wọ inu 3-5 mm jin.

Alapapo iyara (> 100 ° C) nfa eefin ti ara (gbigbo omi cellular).

Ni ipo lilọsiwaju/pulsed, ṣe iranlọwọ gige gige (fun apẹẹrẹ, awọn èèmọ, àsopọ hypertrophic).

1470nm:

Gbigba omi ti o ga pupọ (10× ti o ga ju 980nm), ti o fi opin si ijinle si 0.5-2 mm.

Apẹrẹ fun gige konge (fun apẹẹrẹ, iṣẹ abẹ mucosal) pẹlu itankale igbona kekere.

2. Ablation & Coagulation

Ipo Apapo:

980nm vaporizes àsopọ → 1470nm edidi ohun-elo (collagen shrinkage ni 60-70°C).

Din ẹjẹ silẹ ni awọn ilana bii itọ pirositeti tabi iṣẹ abẹ laryngeal.

3. Hemostasis Mechanism

1470nm:

Ni kiakia ṣe idapọ awọn ohun elo kekere (<3 mm) nipasẹ denaturation collagen ati ibajẹ endothelial.

II. 1470nm Wavelength fun aipe Venous & Awọn iṣọn Varicose

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

Àfojúsùn:Omi ninu ogiri iṣọn-ẹjẹ (kii ṣe igbẹkẹle haemoglobin).

Ilana:

Fi sii okun lesa: Gbigbe Percutaneous sinu iṣọn saphenous nla (GSV).

1470nm lesa ibere ise: O lọra okun pullback (1-2 mm / s).

Awọn ipa igbona:

Iparun endothelial → iṣubu iṣọn.

Collagen contraction → fibrosis yẹ.

2. Awọn anfani Lori 980nm

Awọn ilolu ti o dinku (diẹ ọgbẹ, ipalara nafu ara).

Awọn oṣuwọn pipade ti o ga julọ (> 95%, fun Iwe akọọlẹ ti Iṣẹ abẹ Vascular).

Agbara kekere ti a beere (nitori gbigba omi ti o ga julọ).

III. Ohun elo imuse

Yipada-Igi-gigun Meji:

Afọwọṣe/iyan ipo adaṣe (fun apẹẹrẹ, 980nm fun gige → 1470nm fun lilẹ).

Fiber Optics:

Awọn okun radial (agbara aṣọ fun awọn iṣọn).

Awọn imọran olubasọrọ (fun awọn abẹrẹ gangan).

Awọn ọna itutu:

Afẹfẹ / omi itutu agbaiye lati dena sisun awọ ara.

IV. Ipari

980nm:Ablation ti o jinlẹ, isọdọtun iyara.

1470nm:Egbò coagulation, iṣọn pipade.

Asopọmọra:Awọn iwọn gigun ti o papọ jẹ ki iṣẹ ṣiṣe “ge-ati-ididi” ṣiṣẹ ni iṣẹ abẹ.

Fun awọn paramita ẹrọ kan pato tabi awọn iwadii ile-iwosan, pese ohun elo ti a pinnu (fun apẹẹrẹ, urology, phlebology).
