According to the present invention, a laser beam generating means made of a gas such as CO2 gas and a laser beam generating means made of a solid made of an endaggregate are provided in a single body, so that the laser beam generating means of the gas and the solid, if necessary, such as the laser beam intensity and solution In particular, the present invention relates to a gas and solid state laser surgery apparatus capable of selecting and using laser beams having different characteristics generated in the present invention, and in particular, the present invention includes: a CO 2 gas laser source injecting CO 2 gas into a tube in one main body; A multi-joint guide arm means for guiding a laser beam generated from a gas laser source on a CO 2 tube; and a gas laser beam generation means having a CO 2 gas laser beam irradiation means mounted at a tip of the guide arm means. Separate storage compartment; A laser beam generating source having a sealed cooling chamber having a reflecting surface formed on an inner circumferential wall inside thereof, and having a ND: YAG rod and a fresh lamp inside the sealed cooling chamber; A laser beam for both a gas and a solid is provided on both front and rear sides of the solid state laser beam generating means, with a laser beam exit in which an output mirror and HR mirrors are installed, and a solid state laser beam generation means in which a laser diode for generating a target indication beam is installed in parallel. It is about a surgical instrument.

In addition, the present invention is to form a high-power solid laser beam generating means in the gun-type storage chamber with a handle to hold the handle to direct the location of the tattoo or spot locally on the face or skin with the target indication beam Afterwards, the laser beam can be irradiated and removed by intensively irradiating only on the spot or tattoo area, so that the tattoo or other skin around the spot can be safely used without the risk of adverse effects such as being burned and damaged. By using a solid endadigrod as a laser beam generating source, it is possible to use it economically for a long time without burden of filling or replacing gas.

In general, in a conventional laser surgery machine, as a laser beam generator, a laser surgeon for the treatment of surgery, vascular therapy, and disease in skin tissue is generally used as a laser beam generator using a gas such as CO₂ gas or Ne-He gas. As a method of removing and removing tattoos and spots on the skin, only a solid laser beam source such as Yag rod, which is a kind of jewelry, was used with a laser beam surgery machine installed independently.

However, the conventional laser beam surgery machine as described above is provided with a surgical device that uses only a gas such as CO₂ gas, Ne-He gas, etc. and a surgical device that uses a yag rod for the medium used to obtain a therapeutic laser beam. In order to obtain effective treatment by using laser beams with different characteristics according to the condition of the affected area and the purpose of treatment, a laser beam surgery machine based on gas and a surgical device made of solid yag are purchased separately. It should be done, but such a laser beam surgery machine has a disadvantage that adds a considerable economic burden to the hospital or doctor used, such as a considerable price.

Moreover, the CO2 gas laser surgery machine used in the related art is mostly used as a surgical incision around a wide affected area or a laser acupuncture to place a needle around the affected area. There is a risk that the side effects of getting burned or damaged are limited, and there is a limit that precise medical procedure technology is required, and the error of the point where the laser beam is irradiated is large, and it is very difficult to remove tattoos or spots on the skin. It shows a disadvantage that is not desirable.

Therefore, the present invention was devised to solve the above-mentioned inconveniences and disadvantages, and the present invention provides a CO 2 gas laser beam surgery machine and a solid laser beam surgery machine, which are composed of yag rods, which are conventionally configured in one body. It is possible to select and use laser beams of different characteristics depending on the required treatment conditions or environment, such as medical surgical instruments such as surgery or paramedical procedures such as treatment of skin surfaces such as moles and tattoos. The purpose of the present invention is to provide a laser beam surgery machine capable of performing medical procedures or treatments in various conditions or environments by means of a single laser beam surgery machine.

In addition, the present invention is to produce a laser beam surgery machine for generating a laser beam of various characteristics by providing a CO2 gas laser source for generating a laser beam of different characteristics and a laser source consisting of a yag rod in a single surgical instrument body Another purpose is to reduce the economic burden of the user by being able to provide at low cost.

In addition, the present invention has another object to enable the laser beam generation source to be used economically for a long time without the burden of filling the gas or replacing the tube by using a solid endijag rod.

In addition, the present invention is formed by concentrating both the laser beam generating means and the irradiation means in a single body of the gun type to hold the handle to accurately position the laser beam at the position of the target indication beam appearing on the same point in the laser LED for generating the target indication beam. Another purpose is to provide a gun-type laser beam surgical device that is extremely safe and precise in its handling and manipulation.
