のが使用されていた。When performing dental treatment, X-ray photography is used for various purposes such as diagnosing the affected area and observing the condition of teeth near the affected area. When performing such X-ray photography, it is important to securely support the X-ray film at a predetermined location within the oral cavity.If the X-ray film is not supported securely, the resulting X-ray image will be It has no use as an unclear image. Conventionally, a mechanism shown in FIG. 1 has been used as an X-ray film support mechanism during X-ray photography.

ている。FIG. 2 is a sectional view of a tooth, FIG. 3 is a perspective view of a treatment tool, FIG. 4 is a sectional view of a tooth being treated, and FIG. 5 is a sectional view of a part of the oral cavity. In each figure, the same parts as those shown in FIG. 1 are given the same reference numerals. When an inflamed area 10 occurs at the root end of the tooth 1, the dentist makes a hole 12 in the occlusal surface of the coronal part of the tooth 1, and from there inserts a cleanser (pulp removal needle), which is a treatment tool shown in FIG. ) 11 to the tooth S1 [3 as shown in figure M4, and into the pulp 3': Extract (extraction -! I [), and at the same time use a reamer etc.
Reach o. Thereafter, the affected area 10 is treated through the expanded pulp cavity after pulp extraction. After the treatment of the affected area 10 is completed, the hole 12 is filled with a suitable filling material or the hole 11 is covered with a cover. Such treatment is called gingival therapy.
さて、上記歯肉療法に°おいて、クレンザ−１１の先端

ように載置する等の手段が採用されていた。In order to know this, KX-ray photography is performed. By the way, it is essential to perform this xis shadowing with the cleanser 11 and reamer (root canal expander) still inserted, so the upper and lower ml cannot be interlocked, and the X-ray film package 5 is Support member 8 shown in FIG.
tl - cannot be used. Therefore, conventionally, the X-ray film package 5 was supported and fixed during X# imaging in the gingival therapy by simply holding the X-ray film package 5 with fingers from the direction of arrow A as shown in FIG. A method such as placing it so that it leans against the tooth 1 has been adopted.
しかしながら、このような手段では、Ｘ線フィルム包装

ィルム支持部材２６に形成された擲である。FIG. 6 is a plan view of the X-ray film support device according to the first embodiment of the present invention. In the figure, 20 is a clip. The clip 20 has a knob portion 20a1 a clamping portion 2゜b1 a contact portion 2
0c and a spring 20d. Contact part 2
For 0c, a member with a large frictional force is used. 21 indicates a film support attached to the clip 20. 22 is a support rod attached to the clamping part 20b of the clip 20;
23 is l1g that connects the clamping part 20b and the support rod 22.
This is the 1st flexible connection part. Such a flexible connection part is made of, for example, a sphere and a recess of the same shape, and by fitting the return body into the recess, the support rod 22 can be freely rotated within a wide solid angle. It is configured to allow. 24 is a hollow cylinder supported by the support rod 22, and 24a is a locking portion provided near the open end of the cylinder 24. 25
is an extensible member inserted into the cylinder 24, and is capable of sliding freely within the cylinder 24 with a predetermined resistance force. 25 a is a locking portion provided at one end of the telescopic member 25, and when the telescopic member 25 is pulled out from the cylinder 24, the locking portion 24a prevents the telescopic member 25 from being pulled out from the cylinder 24. It is prevented by binding. 2
6 is a film support member attached to the other end of the elastic member 25, and 26a is a holder formed on the film support member 26 for mounting the X-ray film package 5 thereon.

。If it becomes necessary to take an X-ray during treatment with gingival therapy,
The dentist attaches and supports the X@film package 5 on the film support member 26, and then places the clip 20 on a suitable tooth on the side opposite to the affected tooth. In this case, the clip 20 does not wobble because the teeth are held at the abutting portion 20a where the vibration force is large. Further, the film support 21 is in a state where it does not extend into the oral cavity. Clip 20 on your teeth? ANI
After that, the film support member 26 is directed toward the affected tooth using the first flexible connecting portion 23, and at the same time, the elastic member 25 is pulled out from the cylinder 24, and the film support member 26 is set to reach the affected part position. . Then, this summer, the support body 26 is tilted in an arbitrary direction by the second freely connecting ring part 27, and the three-dimensional angle of the X-ray film package 5 is adjusted. In this way, the X-ray film package 5 is placed at the optimal position and at the optimal angle for X-ray imaging of the required part. It will be supported, and that support is certain. After photographing, the X-ray film package 5 is removed from the film support member 26, the telescopic member 25 is inserted into the cylinder 24, the clip 20 is removed from the teeth, and the entire film is taken out.

にも装着可能となる。Reference numeral 28 denotes a mounting portion formed at a suitable location on the clip 20, for example, on the lower surface of the clamping portion 20b. A film support 21 shown in FIG. 6 is attached to the attachment portion 28 so as to be rotatable by the first flexible connection portion 23. As shown in FIG. The difference between the device of this embodiment and the device of the first embodiment is that in the device of the first embodiment, the film support 21 is attached in the direction in which the clips 20 are held, whereas in this embodiment The only difference in the device in this example is that it is installed in a direction substantially perpendicular to the clamping direction. For this,
The device of this embodiment has the same effects as the device of the first embodiment, and can also be installed in locations where the device of the first embodiment cannot be installed.
