Successfully fabricated laser device in laparoscopic surgery

Center for Laser Technology, Institute of Technology Application (Ministry of Science and Technology) has successfully fabricated three high-quality laser devices that cost much less than imported equipment from abroad.

In Vietnam, Laser has been applied in medicine since the 1980s. However, most of the laser devices currently used in hospitals are imported products, which are very expensive and easy to use. broken by moisture. Each failure must depend on foreign experts, the warranty and repair is very time consuming and expensive.

Cheap, durable, handy

Facing the above situation, scientists of the Center for Laser Technology, Institute of Technology Application (Ministry of Science and Technology), have successfully fabricated the three laser devices in the medical industry including: Laser surgery 45W CO2 laser used in surgical, dermatological, gynecological, cosmetic surgery .; 50mW therapy He-Ne laser is widely used in many specialties such as physiotherapy, rehabilitation .; Infrared semiconductor laser with a capacity of 4.5W for surgery, acupuncture, anti-ulcer, dentistry.

Thai Quang Tung Engineer, Deputy Head of Medical Laser Technology said, compared to the existing products on the market, the laser devices manufactured by the group have many advantages. There are types designed to add parts to digital cameras, to help doctors see the operating area and minimize unwanted effects caused by lasers; There are types designed to add beams to transmit and adjust the section of the laser beam to the area to be treated by patients, replacing optical fiber leads to import with high cost.

The equipment are all tested in the TC-DL-CL Hanoi Branch, the form is beautiful, compact, easy to install, easy to use, much cheaper than imported equipment, only 70%. Currently, these devices are being used for treatment at Da Lieu Hospital, Friendship Hospital, 108 Central Military Hospital, private clinics and many other local hospitals.

Going to master Laser technology

In order to successfully build a trio of laser devices in the medical industry is a process of nearly 10 years of research and research. . TS. Tran Thi Van Anh, Laser Technology Center shared, the center staff keeps regular contact with the Optical Research Institutes, Laser in Beijing, Shanghai (China) to learn from experience and give technology transfer and transfer.

So far, the Center has gradually mastered the technology of manufacturing some laser devices in medicine, has designed and manufactured feeding systems, control systems of laser devices that were not previously done in the country. OK.

Engineer Le Thi Kim Dung, chairman of the project, said in the coming time, the research team will manufacture high-tech medical devices such as laser devices, electric knives used in laparoscopic surgery and laser used in Endoscopic lithotripsy. Successful fabrication of these devices will lead to a complete replacement of the current open surgery method.

Laser (Light Amplification by Stimulated Emission of Radiation-LASER), and means "amplify light by stimulated emission". Laser was invented in the 1960s and is currently used in many different areas such as cutting steel and other metals; distance measurement in military; Medical applications such as eye surgery; Endoscopic.
