General CO2 laser, i.e., continuous CO2 laser, is a free-beam CO2 laser, which usually adopts the way of non-contact between the beam and skin tissue, providing more convenience than conventional surgery, including reduced mechanical damage, increased surrounding tissue being protected, etc., and easier to maintain sterile surgery, compared with other laser surgery, CO2 laser scalpel has strong cutting ability, large tissue absorption coefficient, the Compared with other laser surgeries, CO2 laser scalpel has high cutting ability, high tissue absorption coefficient, small tissue penetration concentration (about 0.23mm), and is less likely to injure arterial vessels during surgery, etc., which makes continuous CO2 laser used in a large number of surgical clinical treatments. However, continuous CO2 is non-selective in terms of tissue damage and is often associated with side effects such as skin scars after surgical treatment. The cutting or vaporization of the lesion also damages normal tissues to varying degrees, thus making it unsuitable for demanding surgical treatments, which severely limits the further application of CO2 laser in medical treatment. In 1983, Aderson and Parrish proposed the principle of “selective photothermal action” for the non-invasive treatment of laser. The main points of this principle are: when the laser reaches the diseased target tissue through the normal tissue, the absorption coefficient of the laser by the target tissue should be greater than that of the normal tissue, and the greater the contrast, the better, so that when the laser destroys the target tissue, the normal tissue is not injured; the thermal relaxation time (TRT) of the target tissue should be greater than the pulse width or action time of the laser, so that the target The thermal relaxation time (TRT) of the target tissue should be greater than the pulse width or action time of the laser, so that the target tissue is too late to spread the heat to the surrounding normal tissue during the laser heating process to protect the surrounding normal tissue. Based on the principle of “selective photothermal action”, the high energy pulse medical equipment represented by ultra-pulsed CO2 laser therapy machine emerged after the 1990s and was successfully applied, making breakthroughs in demanding application areas, especially in laser cosmetology. The development prospect is very broad. Super pulse CO2 laser adopts advanced pulse technology and PWM power control technology, which can not only increase the peak power of laser output in a very short time and provide sufficient energy to the target tissue, but also precisely control the width of each pulse and pulse repetition frequency by PWM signal. By calculating the thermal relaxation time of the target tissue, the pulse width can be controlled to achieve the best surgical results. For example, the thermal relaxation time of capillaries is about 10 μs, which requires a pulse width of less than 10 μs; the thermal relaxation time of skin tissue is about 1 ms, which requires a pulse width of less than 1 ms for the laser for skin resurfacing and wrinkle removal. the biggest difference between modern lasers and lasers of more than 10 years ago lies precisely in the precise control of pulse width, which is the fundamental guarantee of the safety of modern laser treatment. Super pulse laser cosmetic treatment is a new generation of conventional CO2 laser treatment machine, is a multi-purpose, high-performance laser treatment equipment, not only has the common characteristics of continuous CO2 laser scalpel, but also has its own advantages, can output high energy high repetition frequency of the pulse laser, can meet the “laser selective photothermal action” It can quickly and effectively remove diseased target tissues, minimize laser damage to normal tissues, and greatly improve the accuracy and safety of medical clinics. Clinical practice proves that the laser power used by pulsed laser is much lower than that of continuous laser when performing the same procedure, thus causing less tissue reaction, less damage to the surrounding tissues, shorter time, less smoke and clearer field of vision during treatment. The ultra-pulsed CO2 laser can be widely used to remove various body surface moles, warts, corns, sweat duct tumors, lid xanthomas, various small body surface swellings, age spots and many other diseases, and is currently the safest and fastest way to treat such diseases. This technology can also be applied to eye bag surgery, facial and other parts of the face grinding and wrinkle removal, various scar grinding, removal of axillary odor, hair transplantation, surgical hemostasis, etc.
