Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to a laser treatment device for treating diseased areas by irradiating laser light.

2. Description of the Related Art Conventionally, an irradiation preparation switch and an irradiation switch are independently provided at different locations.

This irradiation preparation switch is a switch for preparing the laser oscillation device in advance so that it can emit laser light at any time. On the other hand, the irradiation switch is a switch that applies a signal to a prepared laser oscillation device to actually output laser light.

For example, the irradiation preparation switch is usually installed as a push button switch on the main body of the laser oscillation device, and the irradiation switch is installed as a hand switch or a foot switch.

When performing treatment using such a laser treatment device,
First, the operator turns on the irradiation preparation switch, and then turns on the irradiation switch during treatment to apply laser light to the affected area.

Problems to be Solved by the Invention However, as mentioned above, since two switches are provided at different locations, it is not possible to constantly check whether the irradiation preparation switch is on or not during treatment. In order to confirm this, one must turn one's face toward the irradiation preparation switch, which tends to neglect paying attention to the patient. Also, I didn't realize (or forgot) that the irradiation preparation switch was on.
It is also possible that the irradiation switch is turned on and the irradiation is mistaken.

OBJECTS OF THE INVENTION It is an object of the present invention to provide a laser treatment device that allows an operator to reliably check the states of two types of switches and operate them safely.

An object of the present invention is to provide a laser treatment device that prevents erroneous irradiation of laser light. Furthermore, it is an object of the present invention to provide a laser treatment device that allows the operator to reliably operate the irradiation preparation and irradiation switches using only the operator's feet without having to take his eyes off the affected area, and also allows the operator to check the status of each switch. shall be.

SUMMARY OF THE INVENTION The gist of the present invention is a noser treatment device as set forth in the claims.

Means to solve problems See Figure 2.

The irradiation preparation switch 15, which is a first stage switch, prepares for laser light irradiation. The irradiation switch 16 as a second stage switch irradiates the laser light that is ready for irradiation. Both switches 15, 16 are provided, for example, on the foot switch 4. After turning on the irradiation preparation switch 15, the timer 17 measures a predetermined time.

The irradiation switch 16 cannot be turned on during this predetermined time, but can be turned on after a predetermined time.

Operation The operator can operate two switches 15, 16 on one foot switch 4. Moreover, after turning on the switch 15, the switch 1 is turned on only after a predetermined period of time has elapsed.
Turn on 6 to enable laser light irradiation.

Embodiment FIG. 1 shows an embodiment of the laser treatment apparatus of the present invention.

The laser treatment device is an ophthalmological photocoagulation device, and has a console 1 and a slit lamp part 2. The console 1 is provided with a control section 3. The slit lamp section 2 irradiates the affected part of the patient's eye with laser light.

A foot switch 4 is arranged below the slit lamp section 2.

See Figure 2.

[Laser Oscillator The core laser oscillator 5 is, for example, an argon laser. The laser oscillator 5 has one laser power supply 6 . The laser power source 6 is controlled by a control circuit 7.

In the optical path between the laser oscillator 5 and the optical fiber 8, there are a condenser lens 9, a neutral density filter 10, and a beam stop 11.
is provided.

The neutral density filter 10 is also called a shutter and can be moved forward and backward into the optical path by a driving section 12. Similarly, the beam stop 11 can be moved forward and backward into the optical path by the driving section 13. These drives 12 , 13 are controlled by a control circuit 7 .

[Foot Switch] The foot switch 4 includes an irradiation preparation switch 15 and an irradiation switch 16. The irradiation preparation switch 15 is connected to the timer 17 and the control circuit 7. The irradiation switch 16 is connected to the control circuit 7 via a timer 17.

[Sakuko Manipulation] Next, the operation will be explained with reference to FIGS. 2 and 3.

The operator first turns on a key switch (not shown). This turns on the entire laser treatment device. In this state, the neutral density filter 10 and the beam stop 11 are on the optical path as shown in FIG. The operator steps on the foot switch 4 to turn on the irradiation preparation switch 15.

At the same time that the ON signal of the irradiation preparation switch 15 is transmitted to the timer 17 that sets a predetermined time, the ON signal is transmitted to the control circuit 7, and then the control circuit 7 drives the drive section 13.

This removes the beam stop 11 from the optical path of the laser beam. At that stage, the neutral density filter 10 is on the optical path of the laser beam, so the laser beam is weakened and aimed as aiming light at the eye, which is the diseased area of the patient.

The timer 17 that has set a predetermined time starts measuring (counting) the predetermined time after the ON signal of the irradiation preparation switch 15 is transmitted.

For example, it is 0.3 seconds. Even if the foot switch 4 is further depressed and the irradiation switch 16 is turned on within the predetermined time, the ON signal of the irradiation switch 16 is not transmitted to the control circuit until the predetermined time has elapsed.

After a predetermined period of time has elapsed, the operator further depresses the foot switch 4 to turn on the irradiation switch 16, and the on signal of the irradiation switch 16 is transmitted to the control circuit 7, which drives the drive unit 12. The shutter 10 is removed from the optical path of the laser beam.

At the same time as the shutter 10 opens, the laser beam is irradiated onto the diseased area that has already been aimed at. Thereafter, when the irradiation time is reached, the control circuit 7 inserts the shutter 10 onto the optical path. Beam stop 11 when the treatment is finished and the irradiation preparation switch is turned off.
is inserted onto the optical path and the laser beam is stopped. Then turn off the key switch.

In the above embodiment, the foot switch is provided with the irradiation preparation switch and the irradiation switch, so that the operator can turn on the irradiation switch by stepping on the foot switch.

Note that the irradiation preparation switch and the irradiation switch of the foot switch can be switched in the same manner by using a proximity switch such as a magnetic switch or an ultrasonic switch in addition to a microswitch. Even if the irradiation preparation switch and irradiation switch are provided on a hand switch, a series of operations can be performed, speeding up, and preventing erroneous irradiation.

Further, the irradiation preparation switch may be a touch switch, and the irradiation switch may be a microswitch. In other words, the irradiation preparation switch is turned on by touching the touch switch.

Effects of the Invention According to the invention of claim 1, since the irradiation preparation switch which is the first stage switch and the irradiation switch which is the second stage switch are provided in the same switch, the operation of the irradiation preparation switch and the irradiation switch can be easily performed by the operator. It can be performed as a series of movements without moving the eyes, allowing you to concentrate on the surgery, and it is safe. What's more, you can check the on/off status of both switches by your own touch.

According to the second aspect of the invention, after operating the irradiation preparation switch, which is the first stage switch, the second stage switch, which is the irradiation switch, cannot be operated until a predetermined period of time has elapsed. Therefore, after the first stage switch has been activated,
The second stage switch can be activated after a predetermined time (time to aim). Therefore, an accident in which the second stage switch is suddenly activated and laser light is irradiated will not occur.

According to the third aspect of the invention, since both switches are provided together in a foot switch, the operator can sequentially operate the first stage switch and the second stage switch simply by operating the foot switch. It is safe and allows you to concentrate on the surgery.
