Fibres optiques pour le NIR

Les fibres laser Lightguide CO2 sont un excellent outil pour transmettre la puissance du laser CO2 à des cibles difficilement accessibles.

According to the physical principles of carbon dioxide lasers, a laser beam with a wavelength of 10600 nm is ideally absorbed in water, thereby generating a thermal effect in the water. This is an application laser that can be used everywhere in a gaseous environment (air, which may be abnormal, usually carbon dioxide used in the laparoscopy area, and some other gases besides oxygen, such as inert gases). However, when used in an aquatic environment, it needs to be in direct contact with anatomical surfaces, objects, etc., and strong adjacent phenomena will occur due to thermal effects. Depending on the capacity, the tissue can be cut (reduced power expression) or evaporated tissue (extruded in high power mode). In both cases, the non-laser tissues are less irradiated than lasers with smaller wavelengths (such as smaller or laser lasers), let alone near-infrared wavelengths of 800 to 900 nm or visible light lasers. The second problem is that traditional silica glass fibers cannot transmit lasers with wavelengths above 2400-2600 nm. Therefore, the use of CO 2 lasers is based on a mirror system to achieve a rigid interchangeable configuration that is difficult to enter the depths of the human body. However, the widely used carbon dioxide laser and its rigid mirror beam delivery system are very useful in otolaryngology and ophthalmology. Relatively recently, so-called pipes or hollow fibers have been developed, which enable CO 2 laser wave energy to be released deep into the body cavity and allow doctors to perform very complicated operations there.

Our company has also developed this hollow optical fiber and provided it for medical use. Hollow optical fiber has been used as a CO 2 laser energy distributor, directly used in the surgical treatment of endometriosis in gynecology, and has been relatively widely used. But their applications are very extensive everywhere, no matter how detailed, they also require effective laser treatment. Since hollow laser fibers do not have specific functions for different specific medical fields, they are unified and distinguished only by diameter, but the particularity of the application is determined by the transmission tool (such as handle, Alberan system, etc.). If you want to use a reusable model on the model of these hollow fibers, you can re-sterilize or shorten the CO2 laser on the tip, or refresh the model only on the tip during operation to achieve the best quality of disposable products Features.
