The concept of ultra-pulse was introduced to China by the American Medical Company, which refers to the carbon dioxide laser treatment machine can output pulses with extremely short pulse width, less than 2 milliseconds. Because the pulse width of 2 milliseconds is extremely low compared to the 150 millisecond pulse width of ordinary carbon dioxide laser therapy machines, such pulsed carbon dioxide laser therapy machines are usually called ultra-short pulse width pulse carbon dioxide laser therapy machines in the industry, or ultra-pulsed lasers for short. treatment machine.

Comparison of pulsed carbon dioxide laser treatment machine and ordinary carbon dioxide laser treatment machine:
The pulse width of ordinary carbon dioxide laser therapy machines is too long, and the pulse width is generally 150 milliseconds. Such a long pulse width far exceeds the thermal relaxation (heat dissipation) time of human tissue (the thermal relaxation time of the thinnest skin tissue in the human body is about 2 milliseconds), which makes the continuous exposure time of the laser too long and the photothermal effect too strong. , the scope and degree of thermal damage to the surrounding normal tissue is too large, the blood circulation and metabolism of peripheral microvessels are blocked, especially the thermal damage to the tissue fluid in the loose connective tissue matrix of the dermis, etc., so that the damaged normal tissue cells In the poor state of hypoxia and lack of nutrients, it is not conducive to its repair as soon as possible, and many corresponding side effects will occur, such as heavier postoperative edema, more obvious erythema, long scabbing and scabbing period, more secretions, tissue It has many disadvantages such as slow repair, prone to secondary infection, and side effects such as excessive pigmentation and scarring, especially in facial cosmetic surgery. In order to effectively reduce the scope and degree of thermal damage to surrounding normal tissue cells, it is necessary to compress the pulse width to less than 2 milliseconds under the premise of ensuring a certain pulse energy, which is less than the thermal relaxation of the thinnest skin tissue in the human body time, and at the same time can precisely control the energy density. The pulsed carbon dioxide laser therapy machine is developed under such a concept. Because the pulse width of 2 milliseconds is extremely low compared to the 150 millisecond pulse width of ordinary carbon dioxide laser therapy machines, such pulsed carbon dioxide laser therapy machines are usually called ultra-short pulse width pulse carbon dioxide laser therapy machines in the industry, or ultra-pulsed lasers for short. treatment machine.

Comparison of pulse laser beauty treatment machine and ordinary carbon dioxide laser treatment machine:
Compared with ordinary carbon dioxide laser treatment machines, the pulsed laser beauty treatment machine has a large energy, up to 200 mJ, and an ultra-short pulse width of less than 2 milliseconds. Therefore, the vaporization speed is fast, the thermal damage is extremely small, the tissue coking is not produced, and the adhesion is not formed. At the same time, the action site is properly heated, which stimulates the proliferation and rearrangement of skin collagen, which is more conducive to wound healing.
Ordinary carbon dioxide laser therapy machines have low energy and extremely high pulse width, about 150 milliseconds. Therefore, the cutting speed is slow (the tissue is actually carbonized), the thermal damage is large, the tissue is easily coked, and adhesions are easily formed. There will be no scar formation, and the wound will heal quickly and easily form a scar, which will affect the wound healing.
The pulsed laser treatment machine can accurately grasp the treatment depth, and can perform fine cosmetic surgery such as grinding. It has more indications. In addition to all the operations that ordinary carbon dioxide laser treatment functions can do, it can also perform operations that it cannot do, such as: eye bags Excision, double eyelid plasty; Vaporization removal of syringoma, xanthoma, eyelid wart and other vegetations. Removal of wrinkles, scar removal, freckles, age spots, seborrheic keratosis, red blood, spider nevus. Get rid of underarm odor, etc.
