A long pulse (30-50ms) 532nm laser was used in our experiments, with the pulse duration matching the thermal relaxation time of the vessels and the green laser matching the absorption spectrum peak of the blood.Laser irradiates nude vein vessels directly or exterior skin to finish operation faster and to acquire the practical data for upper enteron varicose vein treatment in several animal experiments performed in vivo. The 5Jenergy pulse allows us to finely occlude rabbit or dog's vein vessels up to 2 mm in diameter when irradiating them off external skin. Blood vessels are occluded at once, and later biopsy specimens show the immediate and long-term lasting occlusion effect. While vessels are irradiated directly, they are usually irradiated to perforate, detailed causes are still under investigation. Animal experiments showed that the long pulse green laser therapy is a safe and effective solution to the vein's occlusion, which promises such laser with high energy of each pulse and 30-50 ms duration is an ideal candidate for vessel diseases treatment.展开更多
