激光切割機的三組效應的特點

首先,溫度效應(thermaleffect):激光切割加工的軟組織切割主要是為了實現這一效果。如果激光能量水分子,使水分子可以興奮的高速動能,流體動能將能夠達到一個好的效果的組織切割,即水分子作為切削介質的使用。水分子可以很容易地吸收激光能量的波長,但不會破壞水分子鍵結構。

First of all, the temperature effect: laser cutting soft tissue cutting is mainly to achieve this effect. If the laser energy water molecules, so that water molecules can excite the high-speed kinetic energy, fluid kinetic energy will be able to achieve a good effect of tissue cutting, that is, the use of water molecules as cutting media. Water molecules can easily absorb the wavelength of laser energy, but do not destroy the bond structure of water molecules.

第二,機械效應(mechanicaleffect):激光切割硬組織能力不是從溫度效應,而是由組織的能量蒸發的水(蒸發),導致組織的壓力(internalpressure)增加,硬組織熔點是沒有達到之前,會導致組織的斷裂(斷裂),這種現象稱為微爆發

Second, mechanical effect: the ability of laser cutting hard tissue is not from the temperature effect, but from the energy of the tissue evaporation of water (evaporation), resulting in an increase in tissue pressure (internal pressure), hard tissue melting point is not reached before, will lead to the fracture of the organization (fracture), this phenomenon is called micro-explosion.

(微爆),溫度的影響并不直接相關。

(micro explosion), the effect of temperature is not directly related.

第三,流體力學效應(hydrodynamiceffect):例如,最新erbium-chromium YSGG激光(ErbiumChromium:Yttrium-Scandium-Gallium-Garnetlaser),主要用于激光激發的水分子產生高速流體動力學。組織將吸收激光能量的溫度將上升,當溫度在370攝氏度到600攝氏度時,組織不會改變,一旦超過600 C時開始凝固,止血可以實現溫度超過1000攝氏度時,細胞之間的水會蒸發,剩下的組織脫水碳化時超過2000°C。

Third, hydrodynamic effects: for example, the latest erbium-chromium YSGG laser (Erbium Chromium: Yttrium-Scandium-Gallium-Garnetlaser) is used to generate high-speed hydrodynamics for laser-excited water molecules. Tissue will absorb laser energy at temperatures ranging from 370 to 600 degrees Celsius, and the tissue will not change. Once it begins to coagulate beyond 600 C, when the hemostatic temperature exceeds 1000 degrees Celsius, water between cells will evaporate, and the remaining tissue will dehydrate and carbonize beyond 2000 degrees C.
