Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a laser scalpel device, and more particularly to a protection means for a switch panel in a laser scalpel device body.

A laser scalpel device includes a laser oscillator, a light guide system, a beam control system such as a shutter, a system control system, and the like. Most of these are housed in the main body of the device, and only the laser scalpel operating section is connected to the main body of the device via an articulated manipulator, a cord, or the like. In use, the operator opens and closes an e-shutter on a laser beam irradiation switch such as a hand switch or a foot switch attached to the laser scalpel operating section to irradiate the laser beam to the affected area at the appropriate time. On the other hand, settings for the laser output or laser light irradiation mode (continuous oscillation, pulse oscillation, etc.) are performed on the switch panel surface of the main body of the apparatus. Normally, these settings are not made by the surgeon himself, but by an auxiliary worker based on verbal instructions from the surgeon. In this case, in the conventional apparatus, there is no particular relationship between the laser beam irradiation switch and the setting switch on the switch panel of the apparatus main body, and both can be operated and set independently.

In the device configured as described above, if an auxiliary worker or the like accidentally touches the switch panel of the device body while the surgeon is opening the shutter using the foot switch 1 or the hand switch, The originally set output and irradiation mode will change.

Changing the settings like this is extremely dangerous for the laser scalpel.

In order to avoid such a danger, a method has been devised in which a cover is screwed onto the switch panel surface of the main body of the laser scalpel device to protect the switches from being accidentally touched. However, if such a measure is taken, it is difficult to open and close the cover, which makes it difficult to perform output setting tasks easily and quickly, and there is a risk of neglecting or forgetting to attach the cover. However, there was a problem in that the function of preventing erroneous operation could not be fully achieved.

The present invention has been made in consideration of these circumstances, and its purpose is to provide safety by eliminating the risk of accidentally touching the setting switches on the switch panel during laser beam irradiation, and to make various setting operations using the setting switches easier. An object of the present invention is to provide a laser scalpel device that can easily and quickly perform the following steps.

In order to achieve the above object, the present invention is characterized by the following configuration. That is, a lid body is provided on the setting switch panel of the main body of the laser scalpel device so as to be openable and closable, and a detector is provided to detect the open/closed state of the lid body and send out an open state signal or a closed state signal. Then, an AND circuit obtains a coincidence signal between the closed state signal from this detector and an ON signal from a laser beam irradiation switch provided in the laser knife operating section, and the Elyre laser scalpel is turned ON based on this coincidence signal. . Thus, the laser beam irradiation can be performed timely only when the lid is closed, and the laser beam irradiation cannot be performed when the lid is open.

Hereinafter, details of the present invention will be clarified with reference to embodiments shown in the drawings.

FIG. 1 is a perspective view showing the entire laser scalpel device. 1
is the main body of the laser scalpel device, which houses a laser oscillator and the like. A switch panel 2 is provided on the front surface of the main body 1, and a lid 3 that can be opened and closed is placed over the switch panel. Further, a hand piece 5, which is one of the laser scalpel operation parts, is attached to the upper surface of the main body 1 via a multi-joint manipulator 4f. Further, a scanner unit 7, which is one of the laser knife operating units, is connected to the lower end of the main body 1 via a cord 6.

FIG. 2 is an enlarged perspective view of the switch panel 2 of the main body 1 of the laser scalpel device.

As is clear from this figure, the switch panel 2 is equipped with an output adjustment switch knob 8, a laser beam irradiation mode changeover switch knob 9, an output display 10, a mode display 11, etc., which are connected to the shaft 12. It is covered with a lid body 3 which is rotatable around the center. Panel 2
A microswitch 13 as a lid opening/closing detector is attached to the left end in the figure.

3(x) and (b) are diagrams showing the operating state of the micro switch f13, and (a) shows the operation lever 14 of the micro switch 13 being pressed by the lid 3 when the lid 3 is closed and the switch is turned off. This shows the ON state. In addition, (b) shows that when the lid body 3 is opened, the micro switch f13
The actuating lever 14 has returned to its original position due to the action of the spring and is in the OFF state.

FIG. 4 is a block diagram showing the function of the microswitch 13. As shown in Figure 4, micro switch 1
3 is closed and the ON signal obtained by closing the laser light irradiation switch Y-15, which is a hand switch or a foot switch provided on the laser knife operating section, is AND. circuit 1
6. The coincidence signal energizes the relay 17, and the contact 17a of the relay 17 operates the shutter opening drive source 18. When the lid 3 is opened to set the irradiation mode, the micro switch f13 is opened. In this state, even if the laser irradiation switch f15 is closed by pressing the foot switch 7, no coincidence signal will be obtained from the AND circuit 16. Therefore, when the lid 3 is open, the opening operation of the laser beam irradiation shutter is prohibited. Thus, even if the switches on the switch panel 2 are operated to set the output, irradiation mode, etc., no danger will occur. After the above setting work is completed, when the lid 3 is closed, the microswitch I3 is turned on. Therefore, in this state, for example, if the foot switch section 7 is turned on, the AND circuit 16
A coincidence signal is output from the relay 17, and the relay 17 is energized. Therefore, the shutter opening operation drive source 18 is activated to open the laser beam irradiation shutter. As a result, the affected area is irradiated with laser light, allowing predetermined treatment to be performed.

In this manner, in this apparatus, the operator cannot touch the switch panel 2 of the apparatus main body 1 because the operator operates the laser scalpel. Therefore it is safe. Furthermore, when the lid 3 is opened to set the switches, opening of the shutter is prohibited, so laser light irradiation is not performed. Therefore, this case is also safe.

It should be noted that the present invention is not limited to the above-mentioned embodiment. For example, in the embodiment described above, a microswitch 13 was used as a detector, but a photo-inclination detector may be used as shown in FIG. In Fig. 5(a) and t(b), 19 is an optical element in which a light emitting element and a light receiving element are arranged facing each other in a U-shaped body, and is a 020 edge and base plate installed on the panel side. When the lid 3 is attached to the body 3 and the lid 3 is closed, the shielding plate 20 is inserted between the optical elements 19 and shields light, as shown in FIG. By inverting the polarity of the signal obtained at this time and supplying it as one input of the AND circuit, if necessary, the shutter can be opened at the appropriate time as in the previous embodiment.

Further, since the opening arm and base plate 19 of the lid body 3 are separated from the optical element 18 as shown in FIG. 3(b), the shutter opening operation is prohibited, contrary to the above case. In this way, the same effects as in the embodiment described above can be achieved.

It goes without saying that various other modifications can be made without departing from the gist of the present invention.

As explained above, according to the present invention, a detector is provided to detect the open/closed state of the lid body, and the output signal from this detector allows timely laser beam irradiation only when the lid body is closed. Since the laser beam cannot be irradiated with the lid open, there is no risk of accidentally touching the setting switch on the switch panel while the laser beam is being irradiated, making it safe. Since the body can be opened and closed, we can provide a laser scalpel device that allows you to easily and quickly perform various setting operations using the setting switch.
