Description

[Detailed description of the invention] (Industrial application field) This invention relates to a surgical medical device that enables a control target to operate only when a surgeon is at a predetermined position with respect to a surgical control target. It concerns equipment.

(Prior art) Conventionally, for example, when treating the fundus of the eye to be examined with an ophthalmic surgery apparatus (control object) such as a laser coagulator,
It is necessary to prevent the device from malfunctioning when the surgeon is not at a predetermined position with respect to the ophthalmic surgery device.

For this reason, conventionally, as shown in FIGS. 6 and 7, a foot switch 1 for ready (standby) is provided, and the foot plate 1a of the foot switch 1 is moved downward by the operator with respect to the switch body 1b. In this case, the control circuit of the laser oscillator can be directly operated by the foot switch by depressing the stroke S (stepping amount). FIG. 8 shows an example in which the foot switch shown in FIG.

(Problem to be Solved by the Invention) However, it is conceivable that the foot switch 1 is erroneously depressed, and in this case, the laser is emitted from the laser coagulator, which is not preferable.

In addition, the foot switch 1 has a short life because it is a mechanical switch, and has a lower reliability than a photoelectric switch or a proximity switch.

Furthermore, the size, shape, stepping amount,
The stepping force and the like differ depending on each manufacturer. On the other hand, the foot switch 1 is not suitable for orientation or orientation because the required content for the size, shape, stepping amount, stepping force, and the like differs depending on the body type and preference of the operator to use. For example, a small female doctor wearing high heels and a large male doctor use the foot switch differently.

In addition, in such a mechanical foot switch, it is necessary to depress the switch by a predetermined stroke with a predetermined depressing force, and there is a problem that long-time use is accompanied by fatigue of the legs (shins). .

Therefore, a first object of the present invention is to provide a surgical medical device in which a control target is not operated even if a foot switch is operated by mistake.

A second object of the present invention is that the size and shape can be used irrespective of the operator's body type and preference, and the operator's fatigue can be reduced by eliminating the need to depress the switch. An object of the present invention is to provide surgical medical equipment.

(Means for Solving the Problems) In order to achieve this object, the present invention provides a laser surgical apparatus having a laser oscillator for generating a laser beam for surgery, and a control circuit for ON-OFF controlling the laser oscillator. A plurality of foot switches disposed in the housing and turned on and off by a foot inserted into the housing, and an operation switch for operating the control circuit, wherein the control circuit is The operation switch is turned on at the same time as at least two of the foot switches are turned on.
In this case, the laser operation device is connected to the foot switch and the operation switch so as to control the operation of the laser oscillator to generate a laser beam.

(Operation) According to such a configuration, the control circuit sets the ready state when at least two or more of the plurality of foot switches are turned on, and controls the operation of the laser oscillator when the operation switch is turned on in this state. Generate a laser beam.

(Embodiment) Hereinafter, an embodiment of the present invention will be described with reference to FIGS. 1 to 5.

1 and 2, the housing 3 has an opening 4 at one end. The housing 3 shown in FIG. 1 has side walls 3a and 3b parallel to each other, but the housing 3 shown in FIG. 2 gradually expands in a tapered shape as the side walls 3a and 3b move toward the opening 4. ing.

Such a housing 3 includes a plurality of photoelectric sensors S1, S2, S3, S

The photoelectric sensor S2 similarly includes a light emitting element A2 and a light receiving element B2. The photoelectric sensor S3 includes a light emitting element A3 and a light receiving element B3. The photoelectric sensor S4 includes a light emitting element A4 and a light receiving element B4. The light emitting elements A1 and A2 and the light receiving elements B1 and B2 are mounted opposite to the side walls 3a and 3b of the housing 3, respectively.
The light receiving elements B3 and B4 are mounted on the upper wall 3c and the bottom wall 3d of the housing 3 so as to face each other. The photoelectric sensor S1 and the light receiving element B1, the photoelectric sensor S2 and the light receiving element B2, the photoelectric sensor S3 and the light receiving element B3, and the photoelectric sensor S4 and the light receiving element B4 each constitute a foot switch.

Such light-receiving element B1, B2, B3, the output of the B4 is as shown in FIG. 3, NOT circuit N1, N2, N3, the input terminal I ₁ of the AND circuit 5 via the N4, I _2, I _3, is input to the I _4. Moreover, the output side of the AND circuit 5 is connected to the control circuit 7 of the medical device via the operation switch 6. When the control circuit 7 receives inputs from the AND circuit 5 and the operation switch 6, the power supply circuit unit (not shown) supplies power to the control target. Here, examples of the surgical medical device include an ophthalmic surgical device such as a laser coagulator and other surgical devices such as a laser scalpel, and a laser oscillator as a control object controlled by the control circuit 7. And the like.

Therefore, the surgeon's foot is inserted into the housing 3 and the light emitting elements A1, A2, A3, A4 of the photoelectric sensors S1, S2, S3, S4 are moved to the light receiving element B.
When the light projected toward 1, B2, B3, B4 is blocked by the operator's foot, the output from each light receiving element B1, B2, B3, B4 is turned off, and NOT circuit N1, A signal of “1” is output from N2, N3, and N4, and a signal of “1” is output from the AND circuit 5. In this state, the control circuit 7 can be operated by turning on the operation switch 6.

In the embodiment described above, all the photoelectric sensors S1, S2,

When the operation switch is turned on at the same time as one or more switches are turned on, the laser oscillator is operated and a laser beam is generated so as to generate a laser beam, so that the foot switch and the operation switch are connected. Only when both of the operation switches are ON, the control circuit operates to operate the controlled object. Thus, even if the foot switch is erroneously operated, the control target is not operated, so that the safety can be further improved.

In addition, the control circuit controls the laser oscillator to generate a laser beam when the operation switch is turned on at the same time that at least two or more of the plurality of foot switches are turned on. Even if one of the plurality of foot switches is turned on by mistake due to being inserted into the housing of the foot switch, if at least two of the plurality of foot switches are not turned on, the operation switch is turned on.
Doing so does not activate the laser oscillator.

As a result, in an operation in which the casing, which is a switch box provided with a foot switch, is usually arranged at a position where it cannot be seen, the operation switch is turned on and the operator is mistakenly injured. Even if the toes enter the housing, it is possible to avoid turning on at least two or more of the plurality of foot switches, so that safety can be ensured twice.
