Holmium laser is a high-tech technology that emerged at the end of the 20th century and is one of the most advanced minimally invasive surgical techniques. It uses pulsed light to activate the pulsed laser generated by the rare element embedded in the yttrium-aluminum-garnet crystal. It uses holmium laser lithotripsy to cut, vaporize, and stop bleeding. It can smash any hard urinary tract. Stones, do not harm the body's soft tissue, a single operation stone crushing rate of more than 95%, the standard for the new age of gravel. The advantages of holmium laser lithotripsy: 1. The world's newest stone treatment method, a major breakthrough in the global minimally invasive stone. 2. It is effective for all kinds of stones (including calcium oxalate and phosphate, carbonate stones, cystine, uric acid stones, etc.). 3, No surgery, the surgical process 10 --- 20 minutes, simultaneous treatment of ureteral stenosis and polyps. 4, Accurate, safe, reliable, no bleeding. 5, Hospitalization time is short, recovery is quick, the cost is lower than traditional surgery. 6, A treatment is about to completely remove the stone, the success rate of a treatment of 98% - 100%, while the treatment rate of extracorporeal shock wave lithotripsy is only 20% - 60% (usually more than twice the treatment). 7, Soft fiber can be through the speculum straight to the stone, the crushed, so through the bladder urethroscope, ureteroscopy, nephroscopy and other into the urinary tract, all urinary tract stones can be treated to reduce trauma and patient suffering Small, restore. Under the guidance of B-ultrasound, through a ureteroscope with a skin-kidney channel diameter of only 3 mm, a holmium laser lithotripsy system was used to crush the stones and drain them along the channels. The small surgical incision (only 4 mm in diameter), compared with the traditional kidney incision and lithotripsy, greatly reduced the incidence of renal hemorrhage, rapid postoperative recovery, short hospital stay, and a high rate of stone exhaustion with good results. Minimally invasive percutaneous nephrolithotomy holmium laser lithotripsy is currently an advanced, effective, minimally invasive treatment for the treatment of kidney stones. It is praised by the majority of patients as a non-invasive lithotripsy and is a gold for modern kidney stones treatment. standard.

As a high-quality transmission medium, optical fiber is changing our lives. It promotes the development of the information age and enables people to swim and enjoy high-definition television programs on the Internet. In the medical field, the “figures” of optical fibers can be seen in both large-scale medical diagnostic imaging devices and implantable medical device products. Due to the increase in the use of fiber optics for minimally invasive surgery, the increased demand for advanced diagnostic techniques, and the rapid development of medical fiber technology, the Medical Laser Fiber market has grown at a significant rate. The number of medical optical fiber applications including X-ray imaging, ophthalmic lasers, phototherapy, laboratory and clinical diagnostics, dental headpieces, surgical and in vitro diagnostic instruments, surgical microscopes, and endoscopy has increased significantly. In addition, the miniaturization of medical devices has also increased the demand for medical fiber technology. 1. Laser Surgery Conventional laser surgery can be used in gynecology, anorectal, surgery, dermatology, dentistry, urology, etc., for treatment such as tissue cutting, vaporization, irradiation, and so on. For body surface lesions, the laser can be transmitted with a simple lens, while for the internal lesions, fiber output is required. The output of the fiber can be installed with a spherical and cylindrical laser diffuser, and can also be filled with scattering media, so that the light Spread evenly around. Among them, the low-hydroxyl silica laser fiber can be used to transmit a 2.14μm He-Ne laser, which is currently gaining more applications in the field of laser lithotripsy. In addition, Quartz Laser Fiber surgery can also be used for oral hard tissue therapy, minimally invasive pharyngeal surgery, condyloma acuminatum and other treatments. 2. Laser Therapy Directly irradiating the affected part with a weak laser (such as a Holmium Laser, a semiconductor laser, etc.) causes a series of biological effects, thereby achieving the purpose of accelerating healing or relieving pain and other auxiliary treatments. For the treatment of small areas of the body surface or part of the cavity (such as the nasal cavity, external auditory meatus, vagina, urethra), such as super pain red light treatment instrument. 3. Photodynamic therapy Photodynamic therapy mainly uses tumor tissues and normal tissues to have different affinity properties for photosensitizers. Tumor tissues absorb and retain more photosensitizers. Photochemical reactions occur under the participation of oxygen in biological tissues when irradiated with light of specific wavelengths. The generation of singlet oxygen and (or) free radicals, destruction of a variety of biological macromolecules in tissues and cells, eventually causing tumor cell death, for therapeutic purposes. An optical fiber can transmit laser light of a specific wavelength to a diseased tissue for long-distance irradiation, and the tip can be made into various shapes.

Color rendering refers to the objective effect produced by light emitted by a light source on an object and the degree of appearance of the true color of the object, which is an important indicator of the illumination light source. The light source with high color rendering performs better on the color, the color seen is close to the natural color, and the light source with low color rendering performs poorly on the color, and the color deviation seen is also large. If the light emitted by the light source contains a proportion of each color of light that is similar to natural light, the colors seen by the human eye are more realistic. The spectral distribution of the light source determines the color rendering of the light source. The color rendering of the light source affects the color of the object observed by the human eye. Quantitative evaluation of the color rendering property of the light source is an important indicator for evaluating the quality of the light source. General artificial lighting sources use the general color rendering index as an evaluation index of color rendering, and the color rendering index is also an important parameter to measure the color characteristics of the light source. According to different application fields, Nanjing Hecho Technology Co., Ltd. launched a new ultra-bright high color rendering index medical Endoscope Light Source Module; ultra-high brightness LED Cold Light Source, and Fiber Optic Illuminators and other products to meet the needs of different customers, welcome The majority of new and old customers to inquire.

Hecho is a professional manufacturer of Fiber Optic Sensors, the sensor can be perfect instead of the Keyence, Omron and other brands of the same type sensors. Today, fiber optic sensors have been widely used in industrial automation, power systems, petroleum industry, civil engineering and other fields. Fiber optic sensors play an important role in the power system, mainly used in the following areas: 1, Fiber sensors in the high-voltage cable temperature and strain measurement applications Ideally, the fiber should be positioned as close as possible to the cable core to more accurately measure the actual temperature of the cable. For the buried power cable, the surface-mount fiber can not accurately reflect the cable load changes, but the Fiber Optic Cable buried at the soil thermal resistance changes are more sensitive, and can reduce the installation cost of optical fiber. 2, Fiber sensors in the electric power sensor application The main characteristics of optical fiber electrical power sensor are: Because electric power sensing involves voltage and current, it usually needs to consider electro-optical and magneto-optic effect simultaneously, and use two kinds of sensing media or one kind of multi-functional medium as sensitive components. So that the structure of fiber optic power sensor head is relatively complex; optical fiber electrical power sensor optical sensor signal sometimes contains both voltage and current signals, so the signal detection and processing methods will also be more complex 3, Optical fiber sensors in the electric power system optical cable monitoring application By measuring the frequency shift and intensity of the Brillouin scattered light along the length of the fiber, the temperature and strain information of the fiber can be obtained, and the sensing distance is far, so it has far-reaching engineering research value.
