What are the applications of laser cutting machines in the medical industry

Fiber laser cutting machine has good applications not only in large-scale product processing industries, but also in some other industries, such as clothing industry and medical industry. In this article, our company provides you with fiber laser What are the relevant answers to the application of the cutting machine in the medical industry?

CO2 laser

CO2 laser is almost absorbed by biological tissues on the surface of 200μm, so it is widely used Used in dermatology and plastic surgery. In addition to epidermal treatment, it can also be used for tissue cutting, excision, epidermal grinding, etc. It plays an important role in cosmetology.

Ruby laser

Ruby laser is a laser used in medical treatment. The long pulse mode is commonly used clinically to penetrate deep into the dermis of the skin, destroy hair follicles, and remove excess hair in the body; the Q switch mode enables melanocytes to absorb a large amount of heat and decompose under the action of ultra-pulse waves, which can effectively treat blue, black, and green tattoos and Various benign pigmented lesions.

The alexandrite laser

The alexandrite laser can be used to remove excess hair on the body. After being modulated by the Q switch, it can be used to remove tattoos and various benign pigmented lesions. Its principle and effect are similar to ruby.

Nd:YAG laser

Nd:YAG laser is widely used in the medical field. It has high conversion rate and high output power. When the single crystal is working, the output power can reach 100 watts, which is better than CO2 gas laser in hemostasis and coagulation. Therefore, it is often used as a scalpel in medicine and is widely used in general surgery, otolaryngology, urology, orthopedics, plastic surgery, etc., to cut tissues with rich blood vessels and greatly reduce bleeding. The Nd:YAG laser has a large pulse energy and is not easily absorbed by water and hemoglobin, so it can penetrate deep into the tissue.

Nd:YAG laser with doubling frequency

Nd:YAG laser can output 532nm green laser, using frequency doubling technology, you can choose appropriate pulse width to treat vascular disease. Because of its shallow penetration, it is generally limited to the treatment of superficial vascular diseases. In addition, the frequency-doubled Nd:YAG laser can also be widely used in the treatment of gastric hemorrhage, hemangioma and microsurgery. It also has a certain therapeutic effect on artificial skin pigment variations such as tattoos and lips caused by red dye particles.

Pulsed dye laser

Pulsed dye laser is a liquid laser with dye as its working substance. Currently commonly used pulsed dye lasers in clinical practice have wavelengths of 532, 577, 585, 590, 595, 600nm, etc., with two pulse widths (450 and 1500ns) and various spot diameters (3mm, 5mm, 7mm, 10mm and 3× 5mm), it is mainly used clinically to treat various vascular diseases.

Semiconductor laser

The power of commonly used 810nm semiconductor laser is 0.5~25~60w, and the treatment mode is 0.1~9.9s single pulse, repetitive pulse and continuous output. Using 400, 600, 1000nm contact and non-contact optical fiber and probe transmission, the vaporization effect is 3 times that of 1064nm, and it has a good hemostatic effect. Intraoperative and postoperative bleeding is small, and the intraoperative beam does not have electrical stimulation of nerves and tissues. The patient has less loss, less bleeding, less pain, faster healing, less complications, and shorter hospital stay. In addition, optical fibers of various inner diameters can be easily matched with any kind of endoscope, and can be flexibly applied in open surgery.

Erbium laser

The erbium laser is a solid-state pulsed laser with a wavelength of 294nm, which belongs to the infrared region invisible to the human eye. The laser pulse frequency is 1-20hz, the energy density is 5j/cm2-20j/cm2, and the pulse energy is 1.5jJ. Erbium laser has unique biological tissue action characteristics, and its wavelength is located at the absorption peak of water. Since more than 70% of the ingredients in the skin are water, the skin tissue has a strong ability to absorb erbium laser. When the erbium laser pulse is applied to the skin, the laser energy is quickly absorbed by the tissue, so that the surface skin is heated up quickly, so as to achieve instant vaporization and separation, and finely remove the keratin of the tissue. The depth of each laser pulse is only 10~20μm, and the thermal damage of the laser is limited to 10~20μm. It is suitable for removing superficial, small and deep wrinkles on hands, neck, and face. It is ideal for skin pigmentation and hair transplantation. Efficacy. Its unique effect makes postoperative pigmentation control in a very small range, especially suitable for dark and oriental skin types.

After the outbreak, many medical device manufacturers are working hard to produce and process protective products and medical devices. Once became a hot spot. However, due to insufficient preparation and shortage of production equipment in some areas, the supply of protective equipment exceeds supply. After a period of adjustment, our protective materials have basically met the needs of citizens. Why does this happen? Why can we produce so many equipment in such a short time? On the one hand, it can be attributed to the overtime production of existing equipment manufacturing enterprises; on the other hand, due to the large-scale supply of production equipment, the demand for expansion of production has been solved to a certain extent. When it comes to equipment manufacturing, we have to mention the application of laser cutting machines in the medical device industry.

Medical devices are related to human life safety and play an important role in human life. The high-precision fiber laser cutting machine protects the safety of human life. Fiber laser cutting machine can process cutting parts with very small wedge angle and aspect ratio. Compared with traditional laser processing, the width, wedge angle and thickness of the recast layer are significantly reduced.
