All-solid-state folding intra-cavity sum frequency yellow orange laser vascular disease therapeutic apparatus

Abstract

The invention discloses all-solid-state folding intra-cavity sum frequency yellow orange laser vascular disease therapeutic apparatus. The therapeutic apparatus comprises a first pump light source and a second pump light source, wherein the first pump light source is connected with a first transmission optical fiber, the first transmission optical fiber is connected with a first optical coupling unit, a first input endoscope, a first laser gain medium and a first bi-color mirror lens are arranged beside the first optical coupling unit in sequence, one end of the first bi-color mirror lens is a sum frequency crystal, the other end of the first bi-color mirror lens is a second bi-color mirror lens, and a total-reflection endoscope is arranged beside the sum frequency crystal; the second pump light source is connected with a second transmission optical fiber, and a second optical coupling unit, a second input endoscope and a second laser gain medium are arranged between the second transmission optical fiber and the second bi-color mirror lens in sequence. The all-solid-state folding intra-cavity sum frequency yellow orange laser vascular disease therapeutic apparatus has the advantages of being small in size, low in weight, compact in structure, available in all-solid-state air cooling, low in electricity consumption, convenient to carry, and capable of improving pumping power and reducing side effects.

Description

technical field [0001] The invention relates to semiconductor laser pumped all-solid-state laser technology, laser resonator design technology, intracavity sum-frequency technology, skin dynamic cooling technology and laser medical beauty technology, in particular to an all-solid-state folded intracavity sum-frequency yellow-orange laser blood vessel Disease treatment device. Background technique [0002] Vascular lesions of the skin include vascular malformations and hemangiomas. Common port wine stains, strawberry hemangiomas, telangiectasia, rosacea, and varicose veins of the lower extremities can occur in various parts of the body surface. In addition to cosmetic defects caused by patients, it can also cause corresponding dysfunction. Traditional treatment methods include drug therapy, liquid nitrogen cryotherapy, injection of vascular sclerosing agents, vascular ligation therapy, and surgery. These non-selective invasive treatments cause great damage to normal skin tis...

AI Technical Summary

Problems solved by technology

However, dye lasers have poor safety, dye degradation and toxicity, high energy consumption, poor stability, etc., making the design of dye lasers very complicated and bulky

At the same time, because the peak power of the pulsed laser is very high, it is easy to cause side effects such as purpura when using this laser to treat skin vascular diseases.
