The medical laser treatment apparatus 1 includes a handpiece 30 and switches (a button unit 31 and a foot switch S) provided in the main body 10 when the handpiece 30 is separated from the mount 40. [ The laser beam can be controlled by the handpiece 30 or the switch provided in the main body 10 when the laser beam is mounted on the mount portion 40. [ Particularly, the medical laser treatment apparatus 1 detects the state where the handpiece 30 is placed on the mount portion 40, corrects the light amount of the laser beam output from the handpiece 30 when the mount state is normal, It is possible to prevent the laser beam from being outputted from the handpiece 30 when the state is abnormal.

This medical laser treatment apparatus 1 is configured such that when the handpiece 30 is detached from the mounting portion 40 and contacts the affected portion of the patient W as shown in Fig. 2 (a), the laser beam of constant intensity You can investigate. 2 (b), when the handpiece 30 is inserted into the mounting portion 40 and is mounted thereon, it senses the state of being stowed in the mounting portion 40, Or the output of the laser beam is originally blocked by the handpiece 30 so that the inside is not burned out.

The medical laser treatment apparatus 1 includes a main body 10, a handpiece 30 connected to the main body 10 by an optical fiber cable 20, a handpiece 30 formed on one side of the main body 10, A sensing part 50 provided inside the mounting part 40 and a control part 70 connected to the sensing part 50 and receiving a sensing signal, can do.

Hereinafter, the components constituting the medical laser treatment apparatus 1 will be described in detail with reference to FIG.

The main body 10 can generate a laser beam having a constant wavelength by operating a laser oscillator 11 that receives power from the outside and generates a laser beam. The main body 10 may include a plurality of laser oscillators, and may output various laser beams according to a user's selection. An optical fiber cable 20, in which an electric wire for transmitting electricity and an optical fiber for transmitting a laser beam are coated with an insulator, is connected to one side of the main body 10.

The optical fiber cable 20 is connected to the handpiece 30 and is connected to the handpiece 30 to guide the laser beam from the main body 10 to the handpiece 30 for delivery and supply electricity. The length of the optical fiber cable 20 can be adjustably adjusted on one side of the main body 10. The optical fiber cable 20 is supported by a cable support 15 installed at the upper end of the main body 10 and can move along the cable support 15 when the length is variable. At this time, the height of the cable bracket 15 is adjusted in accordance with the pulling force of the optical fiber cable 20 so that the curvature of the optical fiber cable 20 is kept small so that the laser beam can be transmitted smoothly to the handpiece 30 can do.

The handpiece 30 can receive a laser beam through the optical fiber cable 20 and control it, and irradiate the affected part of the patient W. [ The handpiece 30 can be easily grasped by the user and irradiated with the laser beam, and can be formed in a shape that can be easily mounted on the mounting portion 40. The handpiece 30 may include a button portion 31 for controlling the output of the laser beam and a lens portion 32 for collecting the laser beam in the front end of the laser beam. The lower end of the lens unit 32 may include a shielding piece 33 that can normally hold the handpiece 30 on the mount 40 and maintain the mount state. Here, the blocking piece 33 may be formed as a protrusion vertically protruding from the center of the groove partially embedded in the handpiece 30.

The mounting portion 40 is formed on one side surface of the main body portion 10, and can mount the handpiece 30 thereon. For example, the mounting portion 40 may be formed in a shape recessed in the front surface of the body portion 10, so that a part of the handpiece can be inserted and mounted.

At least one sensing unit 50 recognizes whether the handpiece 30 is inserted or not, a light amount detecting unit 60 that detects the light amount of the laser beam, a sensing unit 50, and a light amount detecting unit 60 for controlling the output of the laser beam, and the like.

The sensing unit 50 senses whether or not the handpiece 30 is inserted inside the mounting portion 40. [ The sensing unit 50 is disposed adjacent to the light emitting units 51a and 52a to sense light output from the light emitting units 51a and 52a, And light receiving portions 51b and 52b for outputting light to the light receiving portions 51b and 52b.

The sensing unit 50 includes a first sensing unit 51 disposed at the entrance side of the mounting unit 40 and a second sensing unit 52 disposed at the inner side of the mounting unit 40 from the first sensing unit 51, As shown in FIG. The first sensing unit 51 can accurately sense whether the handpiece 30 is inserted into the mounting unit 40 and output a correct signal. The second sensing unit 52 can sense the handpiece 30, It is possible to precisely detect whether or not the blocking piece 33 of the locking piece 33 is held in the correct position and output an accurate signal.

The first sensing unit 51 and the second sensing unit 52 are connected to the control unit 70 when a part of the handpiece 30 is interposed between the light emitting units 51a and 52a and the light receiving units 51b and 52b. ) Can output electricity that can be detected as a digital signal " 0 ". When the hand piece 30 is not interposed between the light emitting portions 51a and 52a and the light receiving portions 51b and 52b, the control unit 70 can output electricity that can be detected as a digital signal '1' .

In other words, the first sensing unit 51 and the second sensing unit 52 sense the handpiece 30 and can sense the digital signal '0' and the digital signal '1' A signal can be output. In this specification, the sensing unit 50 defines a sensing signal as an electrical signal generated by the controller 70 so that the sensing unit 50 senses the digital signal as '0'.

The light amount detector 60 may measure the laser beam output from the handpiece 30 and generate an electric signal for outputting a constant amount of the laser beam. The light amount detection unit 60 may be installed adjacent to the lens unit 32 of the handpiece 30 in a state where the handpiece 30 is normally stationary. The light amount detection unit 60 accurately enters the laser beam output from the handpiece 30, accurately measures the light amount of the laser beam and the temperature of the laser beam, and outputs it as an electric signal. At this time, the electric signal may be a calibration execution signal. The light amount detector 60 transmits a calibration execution signal to the controller 70.

The control unit 70 can adjust the light amount of the laser beam output from the handpiece 30 by calculating the detection signal input from the sensing unit 50 and the electric signal output from the light amount detecting unit 60. The controller 70 may be a micro controller unit (MCU). For example, the control unit 70 is connected to the NOR gate and the light amount detector 60 connected to the first sensing unit 51 and the second sensing unit 52, receives an electric signal, An AND gate connected to the first sensing unit 51 and the second sensing unit 52, a NOT gate for inverting a signal applied from the switch, And a controller for converting a signal applied to the laser oscillator 11 into a reference signal and applying the same to the laser oscillator 11.

When the digital signal '0' is input from the first sensing unit 51 and the second sensing unit 52 through the connection of the plurality of semiconductor devices, the control unit 70 outputs the laser beam, which is output from the handpiece 30, To the calibration standby mode in which the light amount of the light source can be adjusted. When the detection signal outputted from the light amount detection unit 60, that is, the calibration execution signal, is input in the calibration standby mode, calibration is performed to adjust the light amount of the laser beam of the handpiece 30 in response to the calibration execution signal, And can be switched to the execution mode.

In addition, when the calibration mode is in progress, the controller 70 blocks the operation of various switches for controlling the intensity of the laser beam so that the intensity of the laser beam is not adjusted by the user.

3 to 5, the operation between the sensing unit 50 and the control unit 70 will be described in detail when the handpiece is not mounted on the mounting unit and when the handpiece is mounted on the mounting unit.

Fig. 3 is a schematic diagram of the inside of the mounting portion showing the case where the handpiece of Fig. 2 is not mounted on the mounting portion, Fig. 4 is a schematic view of the inside of the mounting portion showing when the handpiece of Fig. Fig. 5 is a schematic diagram of the inside of the mounting portion showing the case where the handpiece of Fig. 2 is normally mounted on the mounting portion.

3, when the handpiece 30 is not mounted on the mounting part 40, both the first sensing part 51 and the second sensing part 52 are connected to the controller 70 via the digital signal '1' And outputs the first sensing signal to the control unit 70. The control unit 70 outputs the first sensing signal to the controller 70. [

In this specification, the operation of the control unit 70 will be described by taking as an example that the control unit 70 is composed of a non-coincidence gate, an AND gate, a switch, an undefined gate, a sum gate and a controller. However, the present invention is not limited to the configuration of the semiconductor devices, and the control unit 70 can detect the position of the handpiece 30 through the connection of various other devices and adjust the light amount of the laser beam It can be formed in various ways.

When the handpiece 30 is not mounted on the mounting part 40, the mismatch gate receives a signal corresponding to the digital signal '1' from the first sensing part 51 and the second sensing part 52, And outputs a first control signal corresponding to '0'. The AND gate receives a signal corresponding to the digital signal '1' from the first sensing unit 51 and the second sensing unit 52 and outputs a second control signal corresponding to the digital signal '1'. The switch receives the first control signal from the mismatched gate having the digital signal '0' and maintains the open state so that the calibration performing signal generated in the light amount detecting unit 60 is not transmitted to the controller 70, And a calibration execution signal applied from the switch is calculated and applied to the laser oscillator 11 so that the laser oscillator 11 can irradiate a laser beam having a predetermined intensity. At this time, the undefined gate inverts the third control signal corresponding to the digital signal '0' outputted from the switch to generate the fourth control signal corresponding to the digital signal '1' and outputs the fourth control signal corresponding to the button unit 33 and the foot switch S, So that the laser beam irradiated from the handpiece 30 can be controlled.

This allows the handpiece 30 to irradiate the laser beam of a predetermined intensity when the handpiece 30 is not stuck in the mount portion 40 and the laser beam output to the outside using the button portion 31 and the foot switch S The beam can be easily controlled.

When the hand piece 30 is inserted into the mounting portion 40 as shown in FIG. 4 but the blocking piece 33 of the hand piece 30 is not inserted between the second sensing portions 52, that is, The first sensing unit 51 outputs a first sensing signal that the control unit 70 can sense as the digital signal '1', and the second sensing unit 52 outputs the first sensing signal when the piece 30 is abnormally mounted. The controller 70 may output a sensing signal that the user 70 can sense as a digital signal '0' and apply the sensing signal to the controller 70.

At this time, the mismatched gate receives the first sensing signal corresponding to the digital signal '1' from the first sensing unit 51 and receives the sensing signal corresponding to the digital signal '0' from the second sensing unit 52 And outputs a first control signal corresponding to the digital signal '0'. The AND gate outputs a second control signal corresponding to the digital signal '0'. The switch receives the first control signal, which is the digital signal '1', from the mismatch gate, So that the calibration execution signal output from the calibration unit 70 can be input to the control unit 70.

That is, the switch forms a calibration standby mode. At this time, the controller computes a digital signal '0' and a calibration execution signal applied to the AND gate and applies the calculated digital signal '0' to the laser oscillator 11 to prevent the laser oscillator 11 from generating a laser beam. The undefined gate inverts the third control signal corresponding to the digital signal '1' output from the switch to generate a fourth control signal corresponding to the digital signal '0' and outputs the fourth control signal corresponding to the button unit 31 and the foot switch S, So that the laser beam is not output from the handpiece 30.

Therefore, when the handpiece 30 is abnormally placed on the mount 40, the medical laser treatment apparatus 1 interrupts the output of the laser beam from the handpiece 30 to prevent the calibration mode from occurring, It is possible to prevent the semiconductor elements of the semiconductor device from being damaged.

5, when the hand piece 30 is normally mounted on the mounting part 40 while the cut-off piece 33 of the hand piece 30 is interposed between the second sensing parts 52, Both the first sensing unit 51 and the second sensing unit 52 may output a sensing signal that the control unit 70 can sense as a digital signal '0' and apply the sensing signal to the control unit 70.

The mismatch gate of the control unit 70 receives a sensing signal (digital signal '0') from the first sensing unit 51 and the second sensing unit 52 and outputs a first control signal corresponding to the digital signal '1' do. The gate outputs a second control signal corresponding to the digital signal " 0 ", and the switch receives the first control signal and maintains the short circuit state. The calibration execution signal output from the light amount detection unit 60 is input to the control unit 70, A calibration standby mode can be formed so that the calibration standby mode can be input.

At this time, the switch receives the first control signal of the digital signal '1' from the mismatched gate to maintain the short-circuited state so that the calibration execution signal generated in the light amount detection unit 60 can be transmitted to the control unit 70, The gate receives a first control signal from the first sensing unit 51 and the second sensing unit 52 and applies a second control signal corresponding to the digital signal '1' to the laser oscillator 11, So that a laser beam of a predetermined intensity can be irradiated from the light source 11.

The light amount detecting unit 60 measures the light amount of the laser beam irradiated from the handpiece 30 or the temperature of the laser beam and outputs a calibration execution signal corresponding to the measured value to the controller 70.

Referring to FIG. 6, a state in which the calibration execution signal is outputted and the calibration mode is performed will be described in detail.

6 is a waveform diagram showing a state in which the handpiece is steadily mounted on the mounting portion and the laser beam irradiated from the handpiece is calibrated.

When a calibration execution signal is input to the controller 70, the controller 70 adjusts the amount of electricity applied to the laser oscillator 11 in response to the calibration execution signal, and adjusts the intensity of the laser beam to a reference intensity have.

For example, when the laser beam output from the handpiece 30 is output as the reference intensity I1 and the intensity of the laser beam output due to the deterioration of the laser oscillator 11 is greater than the reference intensity I1 The light amount detector 60 outputs a calibration execution signal larger than the reference signal. The control unit 70 receives the calibration execution signal larger than the reference signal and outputs the electrical signal in inverse proportion to the calibration execution signal to the laser oscillation unit 11 to reduce the amount of the laser beam output from the handpiece 30 It can be adjusted to the reference intensity. When the laser beam output from the handpiece 30 is output as the reference intensity I1 and the intensity of the laser beam output due to external factors becomes smaller than the reference intensity I1, Outputs a calibration execution signal smaller than the reference signal.

The control unit 70 receives a calibration execution signal smaller than the reference signal and outputs an electric signal in inverse proportion to the calibration execution signal to the laser oscillation unit 11 to increase the light amount of the laser beam output from the handpiece 30 It can be adjusted to the reference intensity.

In this way, when the calibration execution signal is inputted, the control unit 70 can always output the laser beam irradiated from the handpiece 30 at the reference intensity corresponding to the calibration execution signal.

While the present invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, It will be understood. It is therefore to be understood that the above-described embodiments are illustrative in all aspects and not restrictive.
