Embodiment 1

[0033] like figure 2As shown, it is a structural schematic diagram of the present invention, including a first laser generator 1, which is a semiconductor-pumped Nd:YAG crystal, a 532-nanometer pulsed all-solid-state laser with acousto-optic Q-switching and intracavity frequency doubling, and a first laser generator 1 The emitted 532nm intense pulse vaporization cutting laser 10 is incident on the first light combining mirror 3 along 45 degrees, and the side of the first light combining mirror 4 facing the first laser generator 1 is coated with a film layer with high transmittance to 532nm laser light; The second laser generator 2 is a semiconductor-pumped Nd:YAG crystal continuously operating all-solid-state laser that can emit a 1.06 μm continuous coagulation and hemostasis laser. It is incident on the first light combining mirror 2 and is perpendicular to the vaporized cutting laser 10. The side of the first light combining mirror 4 facing the second laser generator 2 is c...

Embodiment 2

[0038] like Figure 4 As shown, it is a schematic structural view of Embodiment 2 of the present invention. In this embodiment, it is roughly the same as Embodiment 1, except that the first laser generator 1 and the second laser generator 2 exchange positions. In this way, the first light combining mirror 4 The side facing the second laser generator 2 is coated with a film layer that is highly transparent to the indicating laser 20 , and the side facing the first laser generator 1 is coated with a film layer that is highly reflective to the vaporization cutting laser 10 . The coagulation and hemostasis laser 20 emitted by the second laser generator 2 enters the first light combining mirror 4 along an angle of 45 degrees, and after being transmitted by the first light combining mirror 4, enters the first reflector 5. The vaporized cutting laser 10 enters the first reflecting mirror 5 after being reflected by the first light combining mirror 4 .

[0039] Of course, the coagulat...

Embodiment 3

[0041] like Figure 5 As shown, it is a structural schematic diagram of Embodiment 3 of the present invention, and its structure is substantially the same as that of Embodiment 1, except that the first laser generator 1 emits a 440nm intense pulse vaporization cutting laser 10 which is reflected by the second mirror 11 into the first laser beam. The light combining mirror 4 and the second reflecting mirror 11 are coated with a film layer highly reflective to the vaporization cutting laser 10 . There is a first shutter 91 and a second shutter 92 between the first light combining mirror 4 and the first mirror 5, both of which are connected with the controller 90, and the second shutter 92 is coated with the vaporization cutting laser 10 and the coagulation The hemostatic laser 20 has a highly reflective film layer, and the reflected vaporization cutting laser 10 and coagulation hemostatic laser 20 are injected into the energy absorber 94, and the third laser generator 3 is conne...

Abstract

The invention relates to a laser therapy system comprising: a first laser generator for generating vaporized slicing laser; a first light-combine mirror which has an angle of 45 degrees to said vaporized slicing laser; a second laser generator for generating coagulated hemostasis laser which has an angle of 45 degrees to the first light-combine mirror and vertical to the vaporized slicing laser; a first reflection mirror with a angle of 45 degrees to the vaporized slicing laser; a third laser generator for generating the guiding laser with an angle of 45 degrees to the first laser reflection mirror and vertical to the vaporized slicing laser; a optical fiber coupler vertical to the guide laser; a optical fiber connected to the optical fiber coupler; a endoscope connected to the optical fiber; and a optical filter connected to the endoscope. Wherein, the first light-combine mirror is plated a layer which is high transparent to the vaporized slicing laser and high reflective to the coagulated hemostasis laser; the first reflection mirror is plated a layer which is high reflective to the vaporized slicing laser and the coagulated hemostasis laser; and the input end of optical fiber coupler is plated a layer which is high transparent to the vaporized slicing laser and the coagulated hemostasis laser.

Description

technical field [0001] The present invention relates to a laser treatment system, especially a laser treatment system which can not only effectively vaporize and cut hemoglobin tissue, but also has good effects of coagulation tissue and hemostasis, and clearly indicates the treatment target. Background technique [0002] The laser has high brightness and high directionality, is easy to control and can be optically focused, and the laser can also be transported into the body cavity by optical fiber. Laser also has the characteristics of monochromaticity and coherence, which makes laser widely used in medicine. Most of the medical applications use the thermal effect of laser energy to coagulate, carbonize and vaporize tissues, so that the body tissues can be ablated or cut to achieve the purpose of treatment. [0003] The 532nm green laser is more suitable for ablation or cutting hemoglobin tissue. Because the 532nm green laser penetrates the tissue at a shallow depth of onl...
