Description

[Detailed description of the invention] This invention makes the frame rod that hangs the dental treatment rubber sheet (rubber dam) bendable both vertically and horizontally, allowing the frame rod to stand up and recover. The frame rod maintains a right angle and other desired angles when it stands up, making it sustainable, allowing dental treatment to treat only the teeth that require treatment, and allowing the surgeon to maintain healthy teeth. The object of the present invention is to obtain a rubber sheet holder for dental treatment that can prevent treatment instruments and other drugs from coming into contact with them.

In the present invention, frame rods divided into two halves are made to face each other in the vertical and horizontal directions, and are connected by pivoting, and a spiral spring is straddled at the connection point of the two, and the spiral springs are connected as described above. It is attached to frame rods facing each other, and is bent at the pivot point of each frame rod so that each frame rod is at a right angle.
Alternatively, a rubber sheet holder for dental treatment is constructed so that it can stand up and restore itself while maintaining a desired angle, and has protrusions for hanging the rubber sheet protruding from the frame rod, and an example of its implementation is shown below. The explanation is as follows.

Reference numerals 1 and 1a designate frame rods, and these frame rods are divided into two parts both vertically and horizontally, especially into two halves. The two halves of the frame rods are joined so as to face each other inwardly, and these parts are pivotally connected. This pivoting means is provided with a protrusion on one of the frame rods 1, a notch in the center of the other frame rod 1a, and the protrusion is inserted into the notch and pivotally supported by a pin 2. Also, the fifth
Frame rods 1 and 1a as shown in FIG.
A guide plate 3 is fixed to one side or both sides of the joint of the frame rods 1 and 1a using pins 2 and 4, and the guide plate 3 is fixed to the frame rod 1 in an arcuate groove 5 bored in the guide plate 3. Insert rod 6. In this case, the tip of one frame rod is shaped like an arc. Reference numeral 7 denotes a spiral spring, which spans the above-mentioned joints provided on each frame rod, and has its both ends opposed to each frame rod with the above-mentioned joints sandwiched between the protrusions 8,Ba
Attach to. At this time, the protrusions 8 and Ba are usually installed horizontally on the outside of each frame rod. 9 is a protrusion for hanging a rubber sheet, 10 is a winged clamp for treatment, 11 is a rubber sheet, 12 is a perforation provided in the rubber sheet 11 corresponding to the location of the tooth requiring treatment, 13 is a line of invagination into the mouth, Reference numeral 14 indicates a latching protrusion projecting upward from the frame rods 1, 1a. The shape of the frame rod does not necessarily matter. Any suitable shape that can be used for dental treatment may be used.
Note that the frame rods 1 and 1a are generally curved upward as shown in FIG.

The operation of the present invention will be explained based on the above-mentioned embodiments.The rubber sheet 11 is fixed to the frame rod using the latching protrusions, and then placed on the patient's lips. The means for doing so are based on the usual methods of dental treatment, such as making a perforation 12. Therefore, if necessary for dental treatment, one half of the frame rods 1, 1a is bent and raised both vertically and horizontally at the pivot point.
It is generally good for this rise to be at a right angle.
During this rise, the guide rod 6 moves in the arcuate groove 5 in the embodiment shown in FIGS. 5 and 6. When each of the frame rods rises, the helical spring 7 supplements the rotational force to the rising action so that this is done semi-automatically, and after rising, firmly maintains the rising until a restoring force is applied to the frame rod. The rise of the frame rod can be stopped and maintained at a desired angle by a pre-designed design. and,
The operator uses the rise of the frame rod as necessary to carry in therapeutic instruments, medicines, etc. through the perforation 12 to treat the tooth in need of treatment. Of course, the clamp 10 can be used as appropriate at this time. In order to restore the raised frame rod, the operator may apply a suitable restoring force by pinching the frame rod with fingers or the like. It is possible. This invention allows half of the frame rod on which the rubber sheet is hung to be bent and raised vertically or horizontally according to the operator's needs during dental treatment, and maintains this state. In addition, the restoration can be performed slowly, which not only facilitates dental treatment, but also has the effect of avoiding the impact of the restoration on the patient's lips and the like.
