Apparatus and method for emitting multi-wavelength laser

An apparatus for emitting multi-wavelength laser beams, the apparatus comprising:

• a main body configured to perform overall control and operation;
• a handpiece which is operated by the control of the main body and is connected to the main body by wire;
• and
• a tip capable of being coupled to one side of the handpiece,
• wherein the main body comprises:
• a first power supply part configured to enable the overall operation;
• a display part which operates by receiving power from the first power supply part and provides a procedure screen and a procedure setting control screen to a patient and an operator;
• a control part which operates by receiving power from the first power supply part and controls the overall operation according to a procedure setting value of the display part;
• a laser beam generation part, which receives power from the first power supply part, operates according to the control of the control part, and generates a laser beam;
• a temperature control part which operates by receiving power from the first power supply part and maintains an appropriate temperature to increase laser beam output efficiency when generating the laser beam in the laser beam generation part;
• and
• a cooling part which operates by receiving power from the first power supply part and outputs cooling gas to a patient's skin,
• wherein the laser beam generation part comprises a first laser beam generator and a second laser beam generator which output laser beams of different wavelengths, respectively, and
• the temperature control part comprises a first temperature control part which controls a temperature of the first laser beam generator to be within a first predetermined temperature range using a first cooling/heating water which flows inside the first laser beam generator, and a second temperature control part which controls a temperature of the second laser beam generator to be within a second predetermined temperature range using a second cooling/heating water which flows inside the second laser beam generator,
• wherein the first temperature control part is configured to,
• in response to detecting that the temperature of the first laser beam generator is higher than the first predetermined temperature range, cool the first cooling/heating water, and
• in response to detecting that the temperature of the first laser beam generator is lower than the first predetermined temperature range, heat the first cooling/heating water,
• wherein the second temperature control part is configured to,
• in response to detecting that the temperature of the second laser beam generator is higher than the second predetermined temperature range, cool the second cooling/heating water, and
• in response to detecting that the temperature of the second laser beam generator is lower than the second predetermined temperature range, heat the second cooling/heating water,
• wherein the cooling part comprises:
• a gas can cover which is attached inside the main body and into which a gas can is inserted;
• a first hose which is coupled to a lower end of the gas can cover and is used as a flow path through which gas of the gas can flows;
• a first pressure sensor which is coupled to a lower part of the gas can cover, operates with power from the first power supply part, and checks whether the gas can is inserted into the gas can cover;
• a cooling gas chamber which is coupled to one side of the first hose and stores cooling gas;
• a first opening/closing valve which controls gas output in a center portion of the first hose except for opposite ends of the first hose located between the gas can cover and the cooling gas chamber and operates with the power of the first power supply part and the control of the control part;
• a first level sensor which is coupled to one side of an upper end of the cooling gas chamber, detects whether there is gas therein, and operates with the power of the first power supply part and the control of the control part;
• a second level sensor which is coupled to one side of a lower end of the cooling gas chamber, detects whether there is gas therein, and operates with the power of the first power supply part and the control of the control part;
• a discharge hole which is coupled to one side surface of the cooling gas chamber and is configured to discharge gas in the cooling gas chamber to the outside;
• a second opening/closing valve which opens the discharge hole to discharge gas in the cooling gas chamber to the outside and operates with the power of the first power supply part and the control of the control part;
• a second pressure sensor which is coupled to a lower end of an inner center of the cooling gas chamber and checks whether there is gas in the cooling gas chamber;
• and
• a second hose which connects the cooling gas chamber with the handpiece and is used as a flow path of cooling gas.
