Hereafter, each structure of this medical light source device is demonstrated in detail.

  FIG. 2 is a block diagram showing an electrical circuit of a medical light source device according to an embodiment of the present invention. The LED illumination unit 1 and the LED driving unit 2 are connected to each other in series or in parallel. Three types of switching to adjust the illumination intensity of the plurality of lithium ion batteries 3, the control unit 4 constituted by, for example, a CPU board, the power on / off switch 5A and the LED illumination unit 1 to high, medium and low The switch unit 5 includes a switch 5 </ b> B, and an AC adapter as a charger 6 that charges the battery 3.

The LED illumination unit 1 and the battery 3 are configured separately from the control unit 10, but are electrically connected during operation. Further, the charger 6 can be connected to the control unit 10 as necessary.

  When the power-on signal is input from the switch unit 5 when the power-on / off switch 5A is turned on, the control unit 4 controls the light emission operation of the LED illumination unit 1 through the LED driving unit 2. When an illumination intensity selection signal is input from the switch unit 5 by operating the changeover switch 5B, the control unit 4 drives the LED so that a constant current according to the designated light intensity is supplied to the LED illumination unit 1. Control part 2.

  FIG. 6 shows a configuration of the LED drive unit 2 that drives the LED illumination unit 1 with a constant current. In the figure, an LED drive unit 2 includes an LED 29 of the LED illumination unit 1 and a drive transistor 23 connected on the collector side thereof, a resistor 24 connected to the emitter side of the transistor 23 and grounded at the other end, and an LED 22 A constant voltage diode 25 connected to the power supply terminal 28 in parallel, a resistor 26 having one end connected to the constant voltage diode 25 and the other end grounded, and the middle point between the constant voltage diode 25 and the resistor 26 is the + The operational amplifier 27 is connected to the input side, the emitter side of the transistor 23 and the middle point of the resistor 24 are connected to the negative input side, and the output side is connected to the base side of the transistor 23. . The other end of the LED 29 of the LED illumination unit 1 connected to the collector side of the transistor 23 is connected to a power supply terminal 28 to which the power of the battery 3 is supplied.

  In the LED drive unit 2 of FIG. 6 configured as described above, when the control unit 4 supplies a voltage corresponding to the designated illumination intensity based on the operation of the changeover switch 5B to the power supply terminal 28, the transistor 23 is applied with the base voltage by the operational amplifier 27. The LED 29 is on and current flows through the LED 29. On the other hand, a current also flows through the path of the constant voltage diode 25 and the resistor 26, and the terminal voltage of the resistor 26 applied to the + input side of the operational amplifier 27 is constant.

  However, when the current flowing through the LED 29 exceeds the set value, the current flowing through the resistor 24 also rises, and the terminal voltage of the resistor 24 applied to the negative input side of the operational amplifier 27 rises. The voltage is controlled so that no current flows through the LED. Constant current operation can be performed by always repeating this.

The current supply for charging the battery 3 from the battery 6 is controlled to charge the battery 3.

  LED light has a small amount of heat generation and has an advantage that an irradiation object is not easily affected by heat even when irradiated for a long time. Therefore, in a medical operation for several hours, the human tissue is not damaged, and it is suitable as a light source device for medical operation.

  In order to attach the LED illuminating unit 1 to the operator's head, the LED illuminating unit 1 is attached using the binocular loupe as a holder 7 in the example of FIG. The binocular loupe is widely used in various fields such as the medical field, precision work, and jewelry processing as a means of enlarging and visually observing the local visual object at hand. 11, a binocular loupe main body 12 (primary mirror) for enlarging the image of the work object, a main mirror attachment portion 13 for attaching the binocular loupe main body 12 to the main mirror attachment frame 11, and the visual acuity of the precision operator It comprises a focus adjustment unit 14 capable of compensation, a primary mirror mounting carrier lens 15 for mounting a binocular loupe body, and a frame vine portion 16 for mounting to a precision operator.

  When the LED illumination unit 1 is attached to the binocular loupe, the LED illumination unit 1 attaches the LED illumination unit 1 to the bridge 17 of the binocular loupe by the mounting means 18. The mounting means 18 includes a pair of opposing plates 52 that sandwich the binocular loupe bridge 17, screw holes 51 provided in the opposing plates 52, and screws 50. The screws 50 are also formed on the binocular loupe bridge 17.

  By combining the binocular loupe and the LED illuminating unit 1 in this manner, the deep depth of focus required for the binocular loupe can be realized deeper.

  The holder 7 is not limited to such a binocular loupe, and may be a hat or a headband. FIG. 4 shows an example in which the headband is used as the holder 7, and the LED illumination unit 1 is attached to the headband. The headband is made of a resin member, and can be fixed by being held on the operator's head by its elasticity. The headband is not limited to such a configuration, and there are various forms of materials such as cloth and rubber.

  Further, the headband illustrated in FIG. 4 is configured integrally with the LED illumination unit 1 and the headband. However, as in the case of the binocular loupe, the mounting means 18 and the clip using the screw 50 shown in FIG. If the LED illuminating unit 1 is appropriately attached to and detached from the headband by a mounting means such as the above, various general-purpose headbands can be used as the holder 7.

  Thus, by mounting the LED illumination unit 1 on the operator's head, sufficient illuminance and irradiation range can be secured at hand even if the operator changes the work position.

  Incidentally, as described above, the LED illumination unit 1 may be attached to the headband, but the LED illumination unit 1 may be configured integrally with the headband. Moreover, although the electric cord from the LED illuminating unit 1 is connected to the control unit 10, it is preferable that the cord is connected via a cord reel around which the cord is wound.

  FIG. 5 shows a battery holding belt 8 that holds the battery 3 so that the operator can attach the battery 3 to a part of the body. As described above, there may be one battery 3, but in this example as well, a plurality of batteries 3 are connected to each other by a cord reel, and the battery 3 and the control unit 10 are also connected by a cord reel. Thus, the battery 3 and the control unit 10 are annularly arranged on the battery holding belt 8. As shown in the drawing, the battery holding belt 8 holds a plurality of batteries 3 in a state where they are embedded in the belt. Thus, the operator can wrap the battery holding belt 8 around his / her waist so that the battery 3 and the control unit 10 can be attached to the body together with the LED illumination unit 1 during the operation. The treatment can be performed while operating the switch 5A and the changeover switch 5B that adjusts the illumination intensity in three ways: high, medium, and low.

  Furthermore, the charger 6 can always be connected to the control unit 10. In this case, since the control unit 4 performs both the control of the LED lighting unit 1 and the charging control of the battery 3 at the same time, light is emitted from the LED lighting unit 1 while charging, so that it continues for a long time. It can also handle work that is too long.

  As described above, according to the present invention, it is possible to realize a light source device in which the operator can attach the LED illumination unit 1 to the head and attach the battery 3 to the body.

  In addition, this invention is not limited to the said embodiment, A various deformation | transformation is possible based on the meaning of this invention, These are not excluded from the range of this invention.

  The present invention relates to a medical light source device that can secure sufficient illuminance and irradiation range for a treatment target at hand by irradiating light from an operator's head during medical surgery, and has industrial applicability. .
