激光切割机的三组效应的特点

首先,温度效应(thermaleffect):激光切割加工的软组织切割主要是为了实现这一效果。如果激光能量水分子,使水分子可以兴奋的高速动能,流体动能将能够达到一个好的效果的组织切割,即水分子作为切削介质的使用。水分子可以很容易地吸收激光能量的波长,但不会破坏水分子键结构。

大发体育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,机械效应(mechanicaleffect):激光切割硬组织能力不是从温度效应,而是由组织的能量蒸发的水(蒸发),导致组织的压力(internalpressure)增加,硬组织熔点是没有达到之前,会导致组织的断裂(断裂),这种现象称为微爆发

大发体育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.

大发体育(微爆),温度的影响并不直接相关。

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

大发体育第三,流体力学效应(hydrodynamiceffect):例如,最新erbium-chromium YSGG激光(ErbiumChromium:Yttrium-Scandium-Gallium-Garnetlaser),主要用于激光激发的水分子产生高速流体动力学。组织将吸收激光能量的温度将上升,当温度在370摄氏度到600摄氏度时,组织不会改变,一旦超过600 C时开始凝固,止血可以实现温度超过1000摄氏度时,细胞之间的水会蒸发,剩下的组织脱水碳化时超过2000°C。

大发体育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.
