2a is a power terminal facing the surface of the locking protrusion 4 and connected to a power source such as a battery provided integrally within the handle member 2. . When the locking protrusion 4 of the handle member 2 is slidably fitted into the notch 3 of the case 1, both the power terminals 1a and 2a are connected to the positive and negative terminals respectively. Reference numeral 5 denotes an uneven surface provided on the surface of the handle member 2, so that the fingers gripping the handle member 2 can easily fit into the surface. Reference numeral 6 denotes a light source such as a halogen lamp installed in the upper space 7 of the case 1, and an arcuate reflecting plate 8 is provided at the base of the lamp. Reference numeral 9 denotes a lamp lighting switch provided at the rear of the case 1, and is connected to the middle of a lead wire 10 for a power circuit connecting the light source 6 and the above-mentioned power source. Reference numeral 11 denotes an optical fiber attached to the tip of the case 1 so as to pass through the inside and outside of the case 1. One end (right side) of this fiber faces the vicinity of the light source 6, and the other end (left end) faces at a predetermined angle. The bent portion 11a is bent.

12 is a heat ray absorption filter arranged on the irradiation axis of the light source 6 to the optical fiber 11; 13 is a multilayer film filter arranged on the same optical axis that allows only light in a predetermined region to pass; 14 is the light source 6; the heat ray It is a cylindrical light-shielding plate that covers the periphery of the absorption filter 12 and the multilayer film filter 13, and its diameter decreases as it goes forward, and its diameter becomes the largest at the rear end.

Reference numeral 15 designates a plurality of intake ports cut out in the main body of the case 1 in front of the light-shielding plate 14, and after the outside air (cold air) is introduced into the upper space 7 through the intake ports 15 by the rotation of the cooling fan. , case 1
This acts to exhaust warm air outward from the rear open end of the vent.

Next, we will discuss the operation.

First, when polymerizing and curing a photocurable dental composition in a photopolymerization range, etc., grasp the handle member 2 fitted to the case 1 with your hand, and turn the switch 9 with your thumb pointing upward. Press to operate. In this way, power is supplied from the battery B serving as a power source in the handle member 2 to the light source 6 via the power terminals 1a, 2a, the lead wire 10, and the switch 9, and the light source 6 emits light. Therefore, the heat ray absorption filter 12 removes heat rays from the light from the light source 6, and the multilayer film filter 13 allows only light in a predetermined frequency range to pass through. Furthermore, the light passing through the multilayer filter 13 is transmitted through the optical fiber 11.
The light is guided to the outside of the case 1 through the light beam, and the photocurable dental composition as the workpiece is irradiated from the outer end thereof. For this reason, such photocurable dental compositions
Temporary polymerization occurs at a speed that depends on the amount of light and the irradiation time. The curing operation by such polymerization can be easily carried out by simply grasping the handle member 2 fitted into the case 1, and since the battery B is integrally housed within the handle member 2, it is commercially available. Enables carrying and carrying out work in areas and places where power is not available. Further, when the battery B is exhausted, only the internal battery can be replaced. Especially if the battery is rechargeable,
It can be removed together with the handle member 2 and used for charging.

For example, if the terminal voltage of battery B drops during or at the end of the polymerization curing process,
By operating the switch 9 again, the battery B can be taken out and used for charging, or the handle member 2 can be used for charging, or it can be replaced with a new one. After charging or replacing, the battery can be subjected to the above-mentioned polymerization and curing operation again. In addition,
In addition to a rechargeable battery, a non-rechargeable battery can also be used as the battery B.

Furthermore, in this invention, the handle member 2 has the locking protrusion 4 that fits into the notch 3 having the dovetail groove 3a provided in the case 1, so the locking protrusion 4 is slidably fitted into the notch 3. This allows the handle member 2 to be easily and quickly attached to and removed from the case 1. As a result, the battery integrated into the handle member 2 can be replaced and charged independently of the case 1, improving convenience. Also,
When the handle member 2 is slidably fitted to the case 1 as described above, the power terminal 2 on the handle member 2 side
Since the terminal a is automatically connected to the power terminal 1a on the case 1 side, current can be reliably passed from the battery B to the light source 6 when the switch 9 is operated.

According to experiments, when a 6V, 50W halogen lamp is used as the light source 6, it is possible to turn on the light source 6 by discharging for about 10 minutes by charging each battery B for 1 hour. It was confirmed that the photocurable dental composition could be used 20 times when the irradiation time was about 30 seconds.

[Effect of idea]

As explained in detail above, according to this invention, the light source is housed in the case, and the power source for providing power to the light source is housed integrally in the handle member, which has a shape that is easy to fit in the hand. It is now possible to modify and mold dental materials while holding it in your hand, and the handling and transportation work can be extremely facilitated and speeded up. In addition, since the light from the light source is led out of the case using an optical fiber,
The effect is that the polymerization and hardening work can be carried out intensively and efficiently while visually observing the condition of the dental material and directly touching it. Furthermore, the battery used is a rechargeable battery, and the integrated handle member can be detachably attached to the case, making it possible to quickly and easily charge and replace the battery along with the handle member.
