Today, medical technology is advancing at an astonishing pace. Among them, a laser with a wavelength of 1470 nanometers is quietly bringing about revolutionary changes in multiple medical treatment fields. This seemingly ordinary infrared laser, with its unique physical properties, is gradually transforming into a sharper and more precise “optical scalpel” in the hands of doctors, opening up a new world in minimally invasive treatments.

 

The 1470nm laser stands out due to its unique interaction with water in biological tissues. This wavelength falls precisely within the range where water molecules have the strongest absorption capacity. As a result, the energy carried by the laser is rapidly absorbed by the water in the tissue and converted into heat energy in an extremely short time. Thanks to its unique tissue structure and low thermal penetration depth, this characteristic provides us with high tissue cutting efficiency and a shallow thermal penetration depth. Moreover, the 1470nm laser can vaporize or cut tissues with lower energy while causing less thermal damage to surrounding healthy tissues (typically less than 1mm), truly achieving the precise effect of “cutting and stopping bleeding simultaneously”. Its unique minimally invasive nature has made it stand out in numerous minimally invasive surgeries, and its wide application has already shown initial success.

 

Core Medical Applications: From Vascular Systems to Prostate Health

Minimally invasive techniques represented by 1470nm lasers have become the “gold standard” tool in endovenous laser ablation (EVLA) for varicose veins in the great saphenous vein in vascular surgery. Doctors carefully insert a thin optical fiber catheter into the affected vein. At this point, the energy released by the laser is absorbed by the water in the vein wall, generating a highly precise thermal effect that causes the vein wall to contract and eventually close. By precisely controlling the thermal damage, postoperative pain for patients is significantly reduced, recovery is faster, and adverse complications such as pigmentation are avoided, resulting in better aesthetic outcomes. This technology has brought hope to millions of patients worldwide, fundamentally revolutionizing the treatment of varicose veins.

 

The in-depth research on benign prostatic hyperplasia (BPH) and the continuous exploration and promotion of 1470nm laser enucleation of the prostate are gradually opening up a new and broad treatment avenue for the many middle-aged and elderly men suffering from BPH. Based on minimally invasive laser surgery technology, the laser is directed at the surgical capsule of the prostate, and the hyperplastic gland is gradually and completely removed (enucleated), then fragmented and completely removed from the body through the cavity. It can be called an efficient “bloodless surgery”, which not only greatly reduces the risk of damage to the prostate capsule and surrounding nerves but also better protects the patient’s urinary control and sexual functions. Compared with traditional transurethral resection, it has more thorough resection effects, lower recurrence rates, and shorter hospital stays, and is gradually becoming one of the preferred surgical methods for patients with large-volume BPH.

 

Performing surgical operations in the narrow nasal cavity or throat requires an extremely high level of precision. With its precise ablation effect, the 1470nm laser has also been widely used in clinical ear, nose, and throat (ENT) surgeries. With its unique photothermal properties, it can be used for nasal turbinate shaping, removal of laryngeal papillomas, and ablation of vocal cord polyps in microsurgical treatments. Its unique precision not only maximally protects the nasal mucosa function and the delicate structures of the larynx and vocal cords but also reduces the formation of adverse reactions such as edema after surgery, thereby better restoring the physiological functions of patients. The application scope of 1470-nanometer laser is continuously expanding. As more and more treatment methods for pain are being discovered, the decompression of nucleus pulposus ablation for intervertebral disc protrusion will provide patients with a new minimally invasive option. In the process of treating tumors, its precise ablation feature is gradually being explored and applied in palliative or radical treatment of some solid tumors. With the continuous emergence of thinner and more flexible optical fibers, minimally invasive surgeries through natural orifices such as the mouth and trachea under endoscopy will also become possible, thus taking a big step forward in scarless minimally invasive surgery.

 

However, along with this comes many challenges faced by the popularization of the technology, such as the current high cost of equipment and the high requirements for doctors, who must undergo specialized training to master the precise energy control and operation skills. As clinical practice deepens and technology continues to optimize, 1470nm laser has already left a deep mark on the map of minimally invasive medicine with its unique advantages of “precision” and “efficiency”, and will surely further promote the development of minimally invasive medicine.

 

Under the background of the continuous iteration of “precise light knife”, from dealing with individual closed varicose veins to difficult-to-operate hyperplastic prostates, it has gradually reshaped the treatment philosophy of modern surgery with less trauma, faster recovery, and better efficacy, bringing higher-quality medical experiences to patients worldwide. By ingeniously integrating the beauty of light science with the mysteries of life in modern medical practice, it showcases the forward-looking, advanced, accessible nature of light medicine, and more importantly, its unique scientificity and cutting-edge contemporaneity.
