  FIGS. 8A and 8B show Example 5 of a periodontal examination treatment instrument with a camera according to the present invention. In the probe 1 of Example 1, teeth generated particularly between a tooth and the surrounding gingiva are shown. The depth of the circumferential pocket is measured without causing pain to the patient, and the probe tip of the probe is aired for the purpose of confirming the presence and location of tartar and foreign matter on the root surface in the periodontal pocket. A patient can be injected into the periodontal pocket by adding an injection nozzle, or by forming the probe itself hollow, and heating the air heated to a temperature close to the body temperature from the injection port at each tip. It is intended to expand the periodontal pocket without causing pain and to diagnose the inside of the periodontal pocket.

The probe 1 of the fifth embodiment shown in FIG. 8A is configured by attaching an air injection nozzle 51 as the air injection means 50 to the probe portion 3. The air injection nozzle 51 has an air injection port 52 at the tip, and the branch pipe 53 bent along the tip direction of the probe section 3 is connected to the main pipe cable 55 together with the branch pipe 54 of the signal cable 46 of the camera unit 40.

  The bent shape of the probe unit 3 is basically one type, but even if there are many types of shapes, the branch pipe 53 is made to follow the tip of the probe unit and the position of the air injection port 52 is set to the probe. The Coanda effect (a phenomenon in which fluid flows along the surface of the object) is obtained by setting air so as to be positioned slightly above the tip of the portion 3, for example, 5 to 10 mm above.

As shown in FIG. 9, the compressed air supplied from the pneumatic pressure source 57 is sent to the pressure control valve 87 when the compressed air supplied from the pneumatic pressure source 57 opens the manual valve 86, as shown in FIG. The pressure is controlled to a desired pressure, and the pressure is displayed on the pressure gauge 88. Further, the air flow is controlled by the flow control cock 90 ahead by opening and closing the foot switch 89 for ON / OFF control of air injection, and the flow rate is displayed on the flow meter 91. The air supply line 7 from the compressed air source 57 having this configuration is connected to the probe 1 via the connection portion 58 of the rear end portion 2 a of the grip portion 2. A probe portion 3 is provided at the tip of the probe 1, and a branch pipe 53 as the air injection nozzle 51 is provided along the tip direction of the probe portion 3.
Further, the branch pipe 53 is provided with an opening 93 for escaping air as an air flow rate control mechanism, so that the pressure for injecting compressed air from the air injection port 52 of the air injection nozzle 51 does not become an abnormal pressure. In 93, an abnormal pressure is released.

  For example, even if the air injection port 53 comes into contact with or is buried in a soft tissue such as gingiva and the air injection port 53 is closed, and the air supply line 7 becomes abnormal pressure, the abnormal pressure is released at the opening 93. The abnormal pressure air is not injected into the periodontal pocket. Thereby, generation | occurrence | production of the bubble in a soft tissue can be prevented. The shape of the opening 93 is not limited to a circle but may be an ellipse or other shapes, and the area thereof is preferably a value that approximates the area of the air injection port 52. If the area of the opening 93 is smaller than the area of the air injection port 52, the amount of released air is excessively reduced, and if it is larger, the amount of released is excessively increased. Further, if the area of the opening 93 approximates the area of the air injection port 52, even if air leaks from the opening 93 during normal air injection, the amount of leakage is so small that there is no problem with normal pressure injection. .

FIG. 10 shows an example in which a hand switch 94 is provided in the grip portion 2 of the probe 1 in place of providing the foot switch 89 in the compressed air source air supply line 7 in FIG. Other configurations are the same as those in FIG. 9, and the same effects can be obtained.

Further, in addition to the above, an overheating control mechanism (not shown) for heating the supplied air to a temperature approximating the body temperature is provided to inject the heated air into the periodontal pocket.

The probe 1 described above is provided with the air injection nozzle 51 for injecting air along the probe unit 3, so that air is injected along the probe unit 3, and the injected air is along the tooth side surface. Since the Coanda effect flowing through is obtained, it becomes possible to open the periodontal pocket with the jet air. That is, the probe 1 can be inserted to the bottom while avoiding these while confirming the calculus and foreign matter in the pocket opened by the air blow with the image, so that erroneous measurement of the pocket depth can be prevented.
Furthermore, by controlling the pressure of the jet air with the flow rate control mechanism and controlling the jet air temperature to a temperature approximating the body temperature, the jet of the periodontal pocket can be obtained without giving a sense of incongruity or pain due to the temperature difference during medical examination. The depth can be measured, and further, the presence of tartar and foreign matter on the root surface in the periodontal pocket and the attachment position thereof can be confirmed through the image.
