In modern medicine, laser treatment is also a kind of light treatment. In the past, ophthalmologists thought that the focused energy of sunlight could be used to treat eye diseases, and it was conceived to focus energy on the retina of the eye, causing small burns, which can weld the broken retina after scab. But the sun contains some invisible rays that can damage the eyes, and techniques such as focusing are not easy to solve.
The green laser pointer is a light with excellent monochromaticity and pure color. The directionality of the laser is good, the light is very concentrated, and the focusing energy is very large. By using laser to treat eye diseases, the focal length and energy can be adjusted arbitrarily, and in a very short period of time, appropriate pulse energy is emitted, and even if the patient blinks, it will not affect the treatment. Lasers have been used to treat a variety of eye diseases.
In medicine, in addition to using green laser pointer to treat eye diseases, it also uses a characteristic of its brightness and directionality to create a laser scalpel (called a light knife). The invention of the laser scalpel improved the backward state of the surgical instrument and greatly improved the quality of the operation. Surgery with a laser scalpel has its own unique advantages. It can concentrate a high-intensity, high-energy laser into a high-energy beam of hair. The laser beam moves on the human body, causing the contacted tissue to vaporize and crack under the action of the high temperature and high pressure of the laser to form a sharp incision. At the same time, the high temperature of the laser during surgery can coagulate and close the small blood vessels that have been cut, thus greatly reducing the bleeding, even without bleeding, and alleviating the suffering of the patient.
Recently, Dr. Yang Lin, a vascular surgeon of the First Affiliated Hospital of Jiaotong University, successfully performed the first laser combined with radiofrequency ablation procedure in a patient with severe lower extremity thromboangiitis obliterans (referred to as “vasculitis”). treatment.
Consider the complexity of the vasculitis lesions and the characteristics of the case (inflammatory changes in the full thickness of the vessel wall). Conventional surgical treatment and interventional treatment are very ineffective in such patients. After multiple preparations, Dr. Yang Lin performed the latest vascular occlusion arterial laser ablation combined with radiofrequency ablation. Successful intraoperative occlusion of the vessel was performed. The inflammatory tissue component, and the use of radiofrequency technology to ablate the peripheral arterial innervation nerve, to achieve the role of continuous expansion of blood vessels.
Dr. Yang Lin’s innovative application of excimer green laser pointer technology ablation of occlusive intravascular inflammatory tissue, and then use radiofrequency technology to ablate the innervated nerve to achieve continuous expansion of blood vessels. The technology is currently the latest international technology for the treatment of lower extremity vasculitis.
