The processor 210 of the main body 200 determines whether or not the direction of the handpiece 300 is set in a direction deviating from the predetermined treatment region based on the positional change or the directional change of the handpiece 300, Can be controlled.

Specifically, when the handpiece 300 is changed from the downward direction to the upward direction, the sensor senses that the handpiece 300 is facing upward, and transmits the sensed signal to the processor 210 of the main body 200 . The processor 210 of the main body 200 determines that the handpiece 300 is not directed to a predetermined treatment region based on the sensed signal and supplies laser from the laser oscillation section 220 to the handpiece 300 Can be blocked.

In this case, the medical laser apparatus 100 can display a predetermined region 721 of the nose, which is an irradiation region to which the laser is to be irradiated, superimposed on the facial image.

The medical laser apparatus 100 may store a reference image corresponding to a predetermined treatment site, a site where the treatment site is prohibited, and a target object to which the laser should not be irradiated, or reference data. The medical laser apparatus 100 can confirm that the predetermined region 721 of the nose corresponds to the region to be treated. If the nose is pre-set as the forbidden area, the medical treatment device may display a message instructing the handpiece 300 to re-orient. For example, the medical laser apparatus 100 may be configured such that "the irradiation area is a part for which the operation is prohibited. Message can be displayed together with the face image.

Referring to 730 of FIG. 7, the medical laser apparatus 100 can superimpose and display the guide image displaying the operable region 731 on the facial image based on the reference image or the reference data. The medical laser apparatus 100 can control the laser to be irradiated to the region corresponding to the operable region by confirming that the direction of the handpiece 300 is focused on the region corresponding to the operable region.

8 illustrates a process of identifying a radiation area to which a laser is to be irradiated before a laser is irradiated in a medical laser device and blocking the laser when the irradiation area is a part of a display of the medical laser device, according to an embodiment FIG.

Referring to 810 of FIG. 8, the medical laser apparatus 100 can photograph the irradiation area to which the laser is to be irradiated, and determine the components in the photographed image. For example, if the direction of the handpiece 300 of the medical laser device 100 is directed to the display 230 of the medical laser device 100, then the medical laser device 100 determines that the component in the captured image is the display 230 ). ≪ / RTI >

Referring to 820 of FIG. 8, when the irradiation area to which the laser is to be irradiated includes a predetermined area of the object to which the laser should not be irradiated, the medical laser device 100 can display a warning message. For example, the medical laser apparatus 100 may determine that the direction of the handpiece 300 is focused on the display 230 from the photographed image, and output a warning alarm. The medical laser apparatus 100 may display the message "The direction of the handpiece 300 is pointing toward the display 230. Place the handpiece 300 in the correct position or face the treatment site."

The medical laser apparatus 100 can control the operation of the handpiece 300 so that the laser is interrupted if the direction of the handpiece 300 is not focused on the predetermined treatment site even after the warning alarm is output.

9 is a flowchart illustrating a method of controlling irradiation of a laser in a medical laser apparatus, according to an embodiment.

In step S910, the medical laser apparatus 100 can photograph the irradiation area to which the laser is to be irradiated through the camera 330 mounted on the handpiece 300. [ The medical laser device 100 can also take an adjacent area of the irradiation area to which the laser is to be irradiated. Here, the camera 330 may be mounted on the handpiece 300 of the medical laser apparatus 100 so as to coincide with the irradiation direction of the laser.

In step S920, the medical laser apparatus 100 can confirm whether the irradiation area is targeted to a predetermined treatment site of the object. For example, the medical laser apparatus 100 may extract at least two feature points from the photographed image. The medical laser device 100 can determine the components in the image based on the position, arrangement, or contours of at least two feature points or two or more feature points. The medical laser apparatus 100 can determine whether the irradiated region is targeted to a predetermined treatment site by determining whether the determined component is a predetermined treatment site of the target object.

As a result of confirmation, if the irradiation region is not targeted to the predetermined treatment region of the object, the medical laser apparatus 100 can operate in accordance with Step S930. For example, if the irradiation region is a region where the treatment site is prohibited or a region corresponding to the object to which the laser should not be irradiated, the medical laser apparatus 100 can operate in accordance with Step S930. On the other hand, if the irradiation region is targeted to a predetermined treatment site of the object, the medical laser apparatus 100 can operate in accordance with Step S950.

In step S930, the medical laser apparatus 100 can control the handpiece 300 so that the laser is not irradiated. For example, the medical laser apparatus 100 may cut off the path through which the laser is transmitted so that the laser is not supplied to the laser irradiating unit of the handpiece 300 at the laser oscillating unit.

In step S940, the medical laser apparatus 100 may output an alarm indicating that the direction of the handpiece 300 should be reset. For example, an alarm may be output as an alert message on the display 230 of the medical laser device 100 or on an external display connected to the medical laser device 100. [ Further, the alarm may be outputted as a voice message or a certain sound from the speaker of the medical laser apparatus 100.

In step S950, the medical laser apparatus 100 can control the handpiece 300 so that the laser is irradiated to a predetermined treatment site. For example, as the user presses the laser irradiation input button, the medical laser apparatus 100 can control the handpiece 300 so that the laser is irradiated to a predetermined treatment site.

10 is a flow chart illustrating a method of controlling irradiation of a laser in a medical laser apparatus, according to another embodiment.

In step S1010, the medical laser apparatus 100 can display on the display 230 an irradiation area to which the laser is irradiated. For example, the medical laser apparatus 100 can display an irradiation region irradiated with a laser before the laser is irradiated on the handpiece 300, on the display 230, from the adjacent region of the irradiation region.

In step S1020, the medical laser apparatus 100 may display a guide image guiding the direction of the handpiece 300 to be reset. For example, when the direction of the handpiece 300 is targeted to a region where the operation is prohibited, the medical laser apparatus 100 can display the guide image indicating the operable region. For example, when the direction of the handpiece 300 is targeted to the configuration of the medical laser device 100, the medical laser device 100 can display the guide image indicating the warning message.

In step S1030, the medical laser apparatus 100 can confirm whether the direction of the handpiece 300 is targeted to a predetermined treatment site of the object. If it is confirmed that the direction of the handpiece 300 is targeted to a predetermined treatment site of the object, the medical laser apparatus 100 can operate according to step S1040. If it is confirmed that the direction of the handpiece 300 is not targeted to the predetermined treatment site of the object, the medical laser apparatus 100 can operate according to step S1020.

In step S1040, the medical laser apparatus 100 can control the handpiece 300 so that the laser is irradiated to a predetermined treatment site.
