Abstract

PURPOSE:To improve safety by generating a sound wave according to the kind of laser beam to inform an engineer of the kind of laser beam when laser beam is selected by a means for selecting sighting laser beam or curing laser beam in a laser irradiation apparatus for curing. CONSTITUTION:When a doctor D turns on a first laser select switch 350, an argon laser 50 is selected by a control device 26, and sighting laser beam L3 is output by turning on a sighting laser switch 300. At this time, the first buzzer 450 corresponding to the sighting laser beam L3 is discontinuously operated. When a first laser output switch is turned on for designated time, the first buzzer 450 is continuously operated to inform the output of laser L1, and laser L1 is applied. When Q-CW-YAG laser 60 is selected by operating a second laser select switch 360, a second buzzer 460 is similarly operated, and the laser beam L3 is output. The second buzzer 460 is continuously blown by operating the second laser output switch, and laser beam L2 is output.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a laser irradiation device for irradiating a treatment section with laser light.

[0002]

2. Description of the Related Art A laser irradiation device, for example, a phototherapy laser device for treating an eye, uses a plurality of laser light sources depending on the treatment content. For example, it has two laser light sources for treatment and irradiates the affected area with laser light for treatment. Furthermore, in order to irradiate the appropriate position of the affected area with this therapeutic laser light,
It has a low power laser light source for aiming.

Which laser light source is used by the operator is visually judged by the numerical value of the wavelength of the laser light in use displayed on the display device. Alternatively, the laser light source is visually confirmed by causing the switch itself for selecting one of the laser light sources to emit light. In another method, the name of the selected laser light source is emitted.

[0004]

As described above, in the related art, since the eye is distracted from the treatment site in order to visually determine the type of the laser light source, it is easy to misunderstand. In addition, since the doctor must concentrate his eyes on the patient's eyes for safety, it is not easy to visually determine the type of the laser light source, and a medical error is likely to occur.

The present invention is to provide a laser irradiation device capable of concentrating and safely performing laser treatment by laser light.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT The laser irradiation apparatus of FIG. 1 is an ophthalmic phototherapy laser apparatus. This device includes an irradiation unit 200 and a main body unit 10.
Has 0.

The irradiation unit 200 is incorporated in a slit lamp. The irradiation unit 200 has an eyepiece lens 40, a support 45, and the like. The eyepiece lens 40 is for the doctor D to observe the inside of the eyeball of the patient H. The support base 45 is for supporting the jaw of the patient H.

The main body 100 includes an operation unit 30, an argon laser 50, a Q-SW-YAG laser 60, a mirror 115,
It has a connecting portion 22.

The operation unit 30 has a display unit 28. The display unit 28 displays the wavelength of laser light and the like. The argon laser 50 and the Q-SW-YAG laser 60 have a main body 100.
It is housed inside. The argon laser 50 generates laser light L1. The Q-SW-YAG laser 60 generates laser light L2. The laser light L1 reaches the eyeball E of the patient H via the mirror 115 and the optical fiber 16. On the other hand, the laser light L2 reaches the eyeball E through the reflection mirror 116 and the optical fiber 16.

The argon laser 50 is a continuous wave laser for photocoagulating, for example, the fundus of the eye E. On the other hand Q-
The SW-YAG laser 60 is a pulse laser for incising the posterior capsule in the eyeball E.

The aiming laser 150 emits the laser light L when irradiating the treatment portion of the eyeball E with the laser light L1 or L2.
Used to aim 1 or L2 in the correct position. The aiming laser beam L3 is sent while being superimposed on the laser beam L1 or L2.

These argon laser 50 and Q-SW-Y
The AG laser 60 and the aiming laser 150 are the control device 2
Controlled by 6. The control device 26 includes an aiming laser switch 300 and a first laser select switch 350.
And the second laser select switch 360 is connected. These switches 300, 350, 360 constitute a laser beam selection means.

Further, the controller 26 has a first buzzer 45.
0 and the second buzzer 460 are connected. These buzzers 450 and 460 form a sound wave generating means.

Operation First, the case of performing photocoagulation treatment on the fundus will be described with reference to FIGS. 1 and 2.

As shown in FIG. 2A, the doctor D turns on the first laser select switch 350. Thereby, the argon laser 50 is selected. When the aiming laser switch 300 is turned on as shown in FIG. 2C, the aiming laser beam L3 is first output. As a result, the first buzzer 450 sounds discontinuously as shown in FIG.

When the doctor D turns on the first laser output switch (not shown) for t hours as shown in FIG. 2 (F), the first buzzer 450 continuously sounds. That is, the argon laser 50 outputs the laser L1 and irradiates the treatment area on the fundus to cause photocoagulation.

Next, the case of incising the posterior capsule in the eyeball E will be described.

As shown in FIG. 2B, the doctor D turns on the second laser select switch 360. This makes Q
The CW-YAG laser 60 is selected. Then, as shown in FIG. 2C, when the aiming laser switch 300 is turned on, the aiming laser beam L3 is first output. As a result, the second buzzer 460 starts discontinuously as shown in FIG.

When the doctor D turns on the second laser output switch (not shown) for t hours as shown in FIG. 2F, the second buzzer 460 continuously sounds. Q-SW-
The YAG laser 60 outputs laser light L2.

As described above, when the therapeutic laser beam L1 or L2 is selected and the aiming laser beam L3 is output, the buzzer sounds discontinuously.

When the therapeutic laser beam L1 or L2 is irradiated, a continuous buzzer sound is generated.

As a result, the doctor D receives the laser beam L for treatment.
It is possible to recognize a selected combination of the laser beams L1 and L2 and the aiming laser beam L3, and it is also possible to simultaneously recognize that the laser beam L1 or L3 for treatment is ready for oscillation or is being irradiated.
Since the therapeutic laser beams L1 and L3 are very dangerous, it is extremely important to know whether the laser beams L1 and L3 are ready for oscillation or are being irradiated.

If necessary, each laser light L1, L2,
The frequency of L3 can be displayed on the display unit 28.

The present invention is not limited to the above embodiment.

For example, the number of therapeutic lasers is not limited to two,
You may provide three or more as needed. Further, it may be possible to distinguish not by continuous or discontinuous sounds but by timbre.

[0028]

According to the first aspect of the present invention, the type and combination of the therapeutic laser beam and the aiming laser beam can be accurately recognized with aural and not visual sense. For this reason, the operator does not have to move his or her line of sight, can concentrate on the surgery, and prevent medical accidents.

According to the second aspect of the present invention, it is possible to accurately recognize a plurality of types of therapeutic laser light by hearing rather than visually. Therefore, it is possible to concentrate on surgery and prevent medical accidents.
