Detailed Implementation

[0020] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0021] Example 1

[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a periodontoscope handle of this utility model includes a probe tip assembly 3, a connecting section 2, and a handle body 1. The connecting section 2 is installed between the probe tip assembly 3 and the handle body 1. One end of the connecting section 2 is bent and tilted upwards. A shaft 4 is installed on the outer wall of the probe tip assembly 3 and the other end of the connecting section 2. A mounting groove is provided on the tilted end of the connecting section 2 and the other end of the handle body 1. A slot 9 is recessed on the inner wall of the mounting groove. A relief groove is provided on the inner wall of the slot 9. A bearing 7 is installed in the mounting groove. The other end of the shaft 4 is installed in the inner ring of the bearing 7 and extends into the slot 9. A positioning post 10 is provided in the relief groove to position the shaft 4. A wire 8 connected to the probe tip assembly 3 and the positioning post 10 is provided in the handle body 1 and the connecting section 2.

[0023] In this embodiment, the handle body 1 has a first wiring channel inside, the connecting section 2 has a second wiring channel 12 inside, and the shaft 4 and the positioning post 10 are both provided with a third wiring channel 6. One end of the wire 8 passes through the first wiring channel, the third wiring channel 6 on one side of the shaft 4 and the positioning post 10, the second wiring channel 12 inside the connecting section 2, and the third wiring channel 6 on the other side of the shaft 4 and the positioning post 10 and is connected to the detection tip assembly 3. The section of the wire 8 inside the positioning post 10 is bonded and fixed to the positioning post 10. The other end of the wire 8 is equipped with a pull rod 5.

[0024] In this embodiment, each of the positioning posts 10 has a positioning groove on one end face facing the relief groove, and the other end of each positioning post 10 is inserted into the positioning groove. The positioning groove, the relief groove and the positioning post 10 are all polygonal in cross-section. A relief space is formed between the positioning post 10 and the relief groove for the positioning post 10 to be pulled out of the positioning groove.

[0025] In this embodiment, a compression spring 11 is installed on one end of the positioning post 10 that is inserted into the relief groove, and the other end of the compression spring 11 is installed on the inner wall surface of the relief groove.

[0026] In this embodiment, all bearings 7 are sealed bearings 7, which prevents impurities and saliva in the mouth from entering the interior of the mounting groove.

[0027] In this embodiment, the connecting segment 2 is arranged in a "C" shape, which allows the connecting segment to better expose the observation area and push the cheek outward. The edges of the connecting segment are chamfered to ensure the smoothness of its surface and greatly reduce discomfort.

[0028] In this embodiment, the connection between the wire 8 and the detection tip assembly 3 is loosely configured. When the wire is pulled outward, it can drive the positioning post. However, since there is a loose wire between the wire and the detection tip assembly, the tension will not directly act on the connection between the wire and the detection tip assembly after being pulled, thus avoiding loosening of the connection.

[0029] Example 2

[0030] A periodontoscope, including the periodontoscope handle described in Example 1.

[0031] This device can be used when inspecting the two rows of teeth on the left or right side. If it is necessary to inspect the teeth on the right side, pull the lever outward. The movement of the lever drives the wire, which in turn pulls the positioning post, causing the positioning post to move out of the positioning slot. After losing the positioning effect of the positioning post, the connecting section can rotate independently around the shaft, and can also rotate the probe tip component around the shaft, thereby changing the angle of the probe tip component and increasing the operating range.

[0032] After rotating to the appropriate angle, release the wire. The rebound energy of the compression spring will push the positioning pin outward, allowing the positioning pin to be inserted into the positioning groove again. This will reposition the rotated shaft and also position the connecting section and the probe tip assembly to ensure stability in subsequent operations.

[0033] As the connecting segment moves into the oral cavity, the outward-arching part of the connecting segment can push the inner side of the cheek outward, increasing the gap between the cheek and the teeth, making it easier to observe. Meanwhile, the left side of the connecting segment can be fully exposed, reducing the area of ​​obstruction to the line of sight and allowing for better observation.

[0034] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
