It’s been more than 60 years since laser technology was invented and it is widely used in industrial manufacturing, communication, medical cosmetology, military weapon and so on. As the COVID-19 pandemic is becoming more and more serious in the world, leading to the shortage of the medical equipment and more attention to the medical industry. Today, we are going to talk about the laser application in medical industry.
Laser eye treatment
The earliest laser application in medical industry is eye treatment. Since 1961, laser technology has been used in retina welding. In the past, most of the people used to do the physical labor, so they don’t have many eye disease. But in the past 20 years, with the advent of large screen televisions, computers, mobile phones and other consumer electronics, many people, especially teenagers have got the nearsightedness. It is estimated that more than 300,000,000 people are near-sighted in our country.
Among various kinds of myopia correction surgeries, the most commonly used one is cornea laser surgery. Nowadays, laser surgery for myopia is pretty mature and gradually becoming recognized by most of the people.
Medical laser device manufacturing
The physical features of laser enables it to perform ultra-precise processing. Many medical device requires high precision, high stability and no pollution in the manufacturing process and laser is no doubt the ideal option.
Take heart stent as an example. Heart stent is placed in the heart and heart is the most important organ in our body, so it requires ultra-high precision. Therefore, laser processing instead of mechanical cutting will be used. However, general laser technique will produce a little burr, inconsistent grooving and other problems. To tackle this problem, many oversea companies began to use femtosecond laser to cut the heart stent. The femtosecond laser won’t leave any burr on the cut edge with smooth surface and no heat damage, creating superior cutting effect for the heart stent.
A second example is the metal medical equipment. Many large medical equipment requires smooth, delicate or even customized casing, such as ultrasonic equipment, ventilator, patient monitoring device, operating table, imaging device. Most of them are made from alloy, aluminum, plastic and so on. Laser technique can be used to perform precise cutting on the metal materials and also perform welding. The perfect example would be fiber laser cutting /welding and semiconductor laser welding in metal and alloy processing. In terms of medical product out packaging, fiber laser marking and UV laser marking have been widely used.
Laser cosmetology has an increasing demand
With the increasing living standard, people become more and more aware of their appearances and they prefer their moles, patch, birthmark, tatoo to be removed. And that’s why the demand of laser cosmetology is becoming quite popular. Nowadays, many hospitals and beauty salons begin to offer the laser cosmetology service. And YAG laser, CO2 laser, semiconductor laser are the most widely used lasers.
Laser application in medical area offers new opportunity for laser cooling system
Laser medical treatment has become an individual segment in medical area and it has developed very rapidly, which stimulates the demand of fiber laser, YAG laser, CO2 laser, semiconductor laser and so on.
Laser application in medical area requires high stability, high precision and medium-high power laser products, so it is quite demanding on the stability of the equipped cooling system. Among domestic high precision
laser water chiller suppliers, S&A Teyu is no doubt the leading one.
S&A Teyu offer recirculating laser chiller units suitable for fiber laser, CO2 laser, UV laser, ultra-fast laser and YAG laser ranging from 1W-10000W. With further laser application in medical area, there will be more opportunities for the laser equipment accessories such as laser water chiller.
