What Is a Laser Scalpel?

The laser scalpel, which takes advantage of the high concentration of laser energy, has its unique features as a surgical "knife" used in surgery. Commonly used carbon dioxide laser "knife", the blade is the focal point where the laser beam gathers, the focal point can be as small as 0.1 mm, and the power density at the focal point reaches 100,000 watts per square centimeter. Wherever such a light "knife" goes, whether it is the skin, muscles, or bones, it will be solved. One of the outstanding advantages of laser "knife" is that it is very brisk. There is no slight mechanical impact when using it; after using a 50-watt laser "knife", the speed of cutting the skin is about 10 cm per second, and the depth of the slit is about 1 mm, which is similar to that of a normal scalpel.

Laser scalpel

The laser scalpel uses the high concentration of laser energy to make it a surgical "knife" for surgical operations.

Using a laser "knife" to cut through bones is almost as "fast" as cutting skin, which is far superior to ordinary scalpels. Generally, a bone saw uses a saw and a chisel. For example, it takes an hour to open a small skull. The doctor is laborious and the patient suffers. Using a laser "knife" can greatly reduce the doctor's

Another outstanding advantage of laser "knife" is the laser pair

So, what does a laser "knife" look like? Although its "blade" is just a small dot with a diameter of 0.1 mm, the body of this "knife" is quite large. Carbon dioxide laser "knife" is generally 2 meters high, 2 meters long, and less than 1 meter wide.

Nowadays, all operations performed with a scalpel can be performed with a laser "knife". The doctor can choose a more suitable method according to the requirements of the surgery. In contrast, laser "knife" can perform operations that ordinary scalpels cannot. With the use of optical fibers, lasers can be drilled into people's stomachs to treat people's illnesses. The doctor matched it with a gastroscope and sent it to the patient's stomach. If a gastric ulcer is found to bleed, as long as the laser is turned on, the bleeding point can be solidified immediately to stop the bleeding. In addition to treating gastric ulcers, lasers can also enter the esophagus, trachea, and abdominal cavity for a variety of operations. In 1982, a scientist at the University of California announced a new technology using lasers: using lasers to remove cholesterol and fat deposits that block arteries. Laser light enters blood vessels through very thin optical fibers.
