980nm surgical diode laser for endovenous laser varicose vein surgery
What Are Varicose Veins?
Veins are vessels that drain blood from the body's peripheral parts and channel it back to the heart. Varicose veins are enlarged, deformed, superficial veins in which blood flow is slowed or even reversed compared to the normal venous circulation. Varicose disease results from stretching of the vein walls and malfunction of the valves that normally direct blood back to the heart. Spider veins, or telangiectasia, are tiny varicose veins.
How Are Varicose Veins Caused?
Ageing and heredity are the largest contributing factors for varicose veins. Women are two to three times more likely to develop varicose veins than men. Hormonal changes produced by puberty, pregnancy, menopause, and sometimes using birth control pills and estrogen promote varicose disease development. Many pregnant women develop varicosities during the first trimester of pregnancy.
Fortunately, veins devloped due to pregnancy will often improve within a few months following delivery. Other predisposing factors include obesity, excessive heat, disorders of the lower limbs (such as flat feet) and prolonged standing – as in occupations such as sales, nursing, teaching, hairdressing, and waitressing. Uncommonly, varicose veins can result from an injury to the leg or a clot in the deep veins, commonly referred to as deep vein thrombosis.
EVLA is the undisputed champion for the treatment of venous reflux disease around the world. It is the treatment with the best evidence for long term success with minimal risk and down time. It requires a specialized facility, laser equipment, and an expert in the procedure.
Procedure for Laser Ablation
The doctor will make a small incision in the skin to insert a very thin catheter. The catheter is carefully inserted in a way that it goes into the vein for treatment with the help of ultrasound imaging. The fiber or electrode is exposed when the surgeon slightly pulls back the catheter. The laser emitting from the catheter’s tip helps enlarge the vein.
The surgeon will then gradually pull the catheter out of the vein, which will heat up the vein. As a result, the vein will collapse and slowly heal shut. The blood will reroute to other veins, and this is how the normal blood flow restores after the procedure.
The procedure for endovenous ablation is usually done on an outpatient basis, which means you will be able to go home the same day you get the treatment. However, some patients may require an admission before the surgery. The doctor will tell you better whether you need to stay or not.
Before the surgeon performs laser ablation, they will numb the skin and surrounding tissues either through local anesthesia or topical application (numbing cream). The doctor will clean and sterilize the area and cover it with a surgical drape.
Berylas 980nm diode laser it is one ideal and cost-effective surgical diode laser for endovenous laser varicose vein surgery
Adopts 980nm wavelength semiconductor fiber coupled laser, transmission laser energy through fiber coupling technology, the laser penetrates deep into the blood vessels, according to the principle of selective photoheat, oxyhemoglobin in red blood cells in blood vessels is the main target color group, after absorbing the laser energy, the heat energy is transmitted to the surrounding endothelial cells, causes damage to the walls of blood vessels and breaks down hemoglobin in the vessels, convert it into small groups of molecules that are absorbed by the tissues, based on the skin barrier science. Meanwhile, the skin can repair and regenerate itself, the crushed hemoglobin and capillaries are absorbed by the skin tissue, the space it occupies is covered by newly grown skin tissue, thus achieves eliminates the red blood purpose.
