Is there a future for intravenous ablation devices?

  Varicose veins   refer to varicose veins and dilation caused by blood stasis, weak wall of venous canal and other factors. Varicose veins can occur in many parts of the body. For example, ulcer is actually a varicose vein. Clinically, esophageal and gastric floor varicose veins, varicocele and abdominal wall varicose veins can be seen clinically. The most common part of varicose veins is in the lower limbs. Varicose veins are tortuous, enlarged veins that typically occur in the lower extremities.  Endovenous laser ablation therapy ( EVLT ) is the most popular new minimally invasive treatment for varicose veins, a minimally invasive procedure that uses catheters, lasers and ultrasound to treat varicose veins.Its advantages: 1. The risk of intravenous laser treatment is small. Less bleeding.2. The efficacy is complete, and the operation is performed under direct vision.3 .The operation is simple, and the treatment time cycle is short.4 .Less severe patients can be perform...

LASER works in ENT Surgery

图片
  Thanks to the constant technological evolution, the   medical laser   who is still the object of ceaseless improvements continuously has been applied in ENT surgery more and more up to now.  Laser benefits in the surgical therapy of otosclerosis are the better control on bleeding and the risk reduction of “floating platina” and acoustic vibratory trauma. These advantages allow it to optimize the functional result and to reduce risks of cochlear damage connected with surgical treatment. The ideal property of tissue interaction of the  laser radiation  in the otosclerosis surgery is the laser’s energy absorption of the platina, that allows the vaporization and avoids the perilymph thermal dispersion. The modality of supply of the pulsate energy enables the tissue cooling between the pauses and reduces the risk of thermal damage of the surrounding structures. And the possibility of using different optical , both in “contact” and “no contact” modality, allows...
