Different from any other visible laser devices, the adoption of a 980nm infrared laser diode module belongs to a near infrared laser devices. It emits invisible and intense infrared laser beam directly from an import 980nm semiconductor IR laser diode, which is mainly used in minimally invasive treatment, diagnostic assistance and precision surgery in the medical field due to its infrared tissue penetration and precise energy focusing ability. Being made with constant power source supply and built in thermal emitting system, this direct diode emission made 980nm infrared dot laser gets good heat dissipation, long time lasting and high stability infrared reference dot projection onto multiple working surfaces constantly.
How can near infrared laser work in medical fields? Comparing with any other visible laser devices, 980nm infrared laser diode module gets even strong laser light penetration ability than those of visible laser devices. Near infrared laser light source is less affected by the scattering and absorption of biological tissues (such as skin and muscles). It can penetrate several millimeters to several centimeters of deep tissues, which is suitable for deep lesion treatment or imaging. At the same time, cooperated with the a qualified glass coated lens and low laser beam divergence of less than 1.5mard fan angle, 980nm infrared dot laser enables high concentration infrared laser light source emission, and converts into ultra clear and precise infrared reference dot at a long extending distance.
In order to achieve even more precise and clearer infrared dot projection at longer distance, this 980nm infrared laser diode module also gets special use of adjustable focus optic lens design. Highly powerful and concentrated infrared laser light and IR dot can accurately act on the target tissue (such as micro-vessels, tumor cells), reducing damage to surrounding healthy tissues. Whatever output power it is selected, owing to its special adoption of APC, ACC driving circuit board, 980nm infrared dot laser is also working well with constant output power emission, and the most reliable infrared dot indication, without effect by overheating and over current impact as well. In addition, it can greatly avoid tissue burns caused by abnormal power. At the same time, infrared laser light is invisible to the naked eye and needs to be positioned with red light indication to ensure accurate positioning of the target area during operation.
Main application in the medical field
Minimally invasive treatment:
Treatment of vascular diseases: In the treatment of varicose veins, hemangiomas, etc., 980nm laser diode module can be efficiently absorbed by hemoglobin in the blood, and the blood vessel wall can be contracted and closed through the photothermal effect to achieve minimally invasive ablation, which is less traumatic and recovers faster than traditional surgery.
Otorhinolaryngology treatment: It is used for minimally invasive surgeries such as tonsil hypertrophy and nasal polyps. The infrared dot light spot can accurately act on the diseased tissue, reduce damage to the surrounding healthy mucosa, and reduce the risk of postoperative complications.
Research and application of photothermal therapy:
In basic research and clinical treatment of tumors, with the help of nano-drug delivery systems (such as gold nanoparticles), 980nm infrared alignment lasers can penetrate deep tissues, accurately heat the tumor site through photothermal conversion, achieve local high temperature killing of cancer cells, and reduce the impact on normal tissues.
Diagnosis and imaging assistance:
As a near-infrared light source to assist biological imaging, for example, in intraoperative navigation, by stimulating tumor-specific fluorescent probes, 980nm IR dot laser can help doctors identify tiny tumor lesions or tumor boundaries, and improve the accuracy of surgical resection.
Physical therapy and rehabilitation:
In the physical therapy of chronic pain and inflammation, low-power 980nm infrared alignment lasers can penetrate subcutaneous tissues, promote local blood circulation and tissue repair, and relieve symptoms such as muscle strain and joint inflammation.
