Products Description:
What is Endovenous Laser Ablation (EVLA)?
During the 45-minutes procedure, a laser catheter is inserted into the defective vein. This is usually performed under local anesthesia using ultrasound guidance. The laser heats the lining within the vein, damaging it and causing it to shrink, and seal shut. Once this happens, the closed vein can no longer carry blood, eliminating vein bulging by correcting the root of the problem. Because these veins are superficial, they are not necessary for the transfer of oxygen-depleted blood back to the heart.
This function will be naturally diverted to the healthy veins. In fact, because a varicose vein by definition is damaged, it can actually be detrimental to your overall circulatory health. Although not life threatening, it should be addressed before further complications develop.
Treatment Theory
Laser interaction with tissue depends on the wavelength of choice. The Laseev laser comes in 2 versions - the 980nm and the 1470nm.
1.The 980nm laser with equal absorption in water and blood, offers a robust all-purpose surgical tool, and at 30Watts of output, a high power source for endovascular work.
2.The 1470nm laser with significantly higher absorption in water, provides a superior precision instrument for reduced collateral thermal damage around venous structures.Accordingly, it is highly recommended for endovascular work.
The 980+1470nm diode laser offers a wavelength with superior performance for ablation of diseased veins - 1470 nm.The EVLT is effective, safe, quick and painless. This technique is lighter than the traditional surgery
Optimal Laser 1470nm
Laser wavelength 1470 is, at least, 5 times better absorbed by water and oxyhemoglobin than 980nm laser, allowing selective destruction of the vein, with less energy and reducing side effects.
As a water-specific laser, the TR1470nm laser targets water as the chromophore to absorb the laser energy. Since the vein structure is mostly water, it is theorized that the 1470 nm laser wavelength efficiently heats endothelial cells with a low risk of collateral damage, resulting in an optimal vein ablation.
Optimal wavelength 980+1470nm is coupled with optimal energy delivery when using our 360 radial fibers - the highest quality circular emission fibers.Dedicated laser marking;Ensures precise positioning of the probe.
360°Radial Fiber 600um
TRIANGELASER 360 fiber technology provides you with the efficiency of circular emission, ensuring deposition of energy directly on
the vessel wall.
The tip of the fiber is comprised of an extra smooth glass capillary, directly connected to a marked smooth jacket, allowing easy
direct insertion into the vein.The fiber uilizes a simple procedure kit with a short introducer, reducing steps and procedure time.
Key Advantages
1.Circular emission technology
2.Reduced number of procedural steps
3.Very safe and smooth insertion
Advantage:
Endovenous occlusion of great saphenous vain and small saphenus vain
The procedure is performed in the clinic with topical anesthetic cream and takes approximately 30-45 minutes. There is minimal or no pain and no downtime, the patient can resume normal activity immediately. This treatment should be performed 6-8 weeks apart and for best results, avoidance of direct sunlight to the treated area is recommended.
EVLT-advantages of the method:
1.Does not require hospitalisation(patient can go home even 20 minutes after treatment)
2.Local anaesthesia
3.Short time of treatment
4.No incisionsor post-surgical scars
5.Quick return to dailya ctivities(usually 1-2days)
6.High effectiveness
7.High level of treatment safety
8.Very good aesthetic effect
What's the theory of the laser treatment?
Pilot high energy into veins, then tiny bubbles is generated because of the scattering character of the diode laser. Those bubbles transmit energt to the veins wall and make the blood to coagulate at the same time. 1-2 weekes after operteion, vein cavity contracts slightly,vein wall builds up, no blood flow in the operated section, Vein cavity obstructed by the vein wall over built uo.Bultrasonic wave indicates low echo,uncompressionable differing from acute great saphenous vein herombus. The vein wall
inflammation abates serveral weeks after successful oeration and the vein diameter has reduced fro several months, the majority of the veins froms segmental fibrosis and difficult to be identfied.
