Dual-wavelength laser treatment device

Abstract

The invention discloses a dual-wavelength laser treatment device. The dual-wavelength laser treatment device comprises a main control device, a medical semiconductor laser, a pumping semiconductor laser, a solid laser resonator, a beam combination device, an output power monitoring device, an output light transmission system, a first heat dissipation device, a second heat dissipation device, a third heat dissipation device, a medical semiconductor laser driver, a pumping semiconductor laser driver, a switching device, a display device and a laser synchronous signal. By combining infrared laser output by the semiconductor lasers and visible laser output by the solid laser, the therapeutic apparatus can treat lesion vessels of different diameters and depths on facial skins; and moreover, a dual-wavelength beam combination system is adopted to couple two kinds of laser into the same optical fiber, and the infrared spectrum absorption effect of tissues is strengthened by using visible light so as to enhance the therapeutic effect.

Description

technical field [0001] The invention belongs to the field of medical instruments, in particular to a laser therapy apparatus, and more specifically to a dual-wavelength laser therapy device. [0002] Background technique [0003] Skin vascular lesions include two categories of vascular malformations and hemangiomas. Common port-wine stains, strawberry hemangiomas, telangiectasias, rosacea, and varicose veins of the lower extremities can occur in various parts of the body surface. In addition to cosmetic defects, it can also cause corresponding dysfunction. Traditional treatment methods include drug therapy, liquid nitrogen cryotherapy, injection of vascular sclerosing agent, vascular ligation therapy and surgery, etc. These non-selective invasive treatments cause great damage to normal skin tissue, often accompanied by scarring, pigment changes, etc. Unacceptable complications for patients. With the application of laser technology in the medical field, it provides an effe...
