[0036] In order to enable those skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of this application.

[0037] In the prior art, a dental endoscope is generally disposed on a handle, and a working tip is fixedly disposed at one end of the handle. When working, the working tip is inserted between the gums and the tooth roots so that the periodontal condition can be observed through the lens disposed on the handle. When observing the periodontal condition of different teeth, the posture of holding the handle needs to be adjusted so that the working tip can adapt to the teeth. When it is difficult to find a suitable angle to adapt the working tip to the teeth even after adjusting the posture of holding the handle, a different working tip needs to be replaced to adapt the working tip to the teeth, and it is inconvenient to adjust the angle of the working tip.

[0038] See also Figure 1 , Figure 2 , Figure 3 Figure 4 and Figure 5 As shown, in one embodiment, the present application provides a periodontal camera handle with a rotatable working head, comprising: a handle body 10, a camera assembly 11 and a working head 20; the working head 20 comprises a connecting head 21, a window 22 and a working tip 23;

[0039] A sensor component 12 is disposed inside the handle body 10, and the sensor component 12 is electrically connected to the camera component 11;

[0040] The shooting angle of the camera assembly 11 corresponds to the window 22, so that the camera assembly 11 can shoot the periodontal observation area through the window 22;

[0041] The connecting head 21 is sleeved on one end of the handle body 10, and the working head 20 and the handle body 10 are rotatably connected through the connecting head 21;

[0042] When the working head 20 rotates, the working tip 23 is driven to rotate so that the angle of the working tip 23 is adapted to the tooth.

[0043] It should be noted that the working tip 23 is in a curved shape, with the convex surface being the appearance surface facing outward (the side away from the central axis of the connector 21), and the concave surface facing inward (the side close to the central axis of the connector 21). The concave surface is used to fit the teeth, and different holding postures and the position of the concave surface of the working tip 23 relative to the handle will affect the fit between the concave surface and the teeth. Therefore, a method of adjusting the angle of the working tip 23 appropriately is required to make the concave surface of the working tip 23 more suitable for specific teeth.

[0044] It should be noted that, during work, the working head 20 is rotated to a suitable angle so that the concave surface of the working tip 23 is matched with the first tooth. Since the sensor component 12 is electrically connected to the camera component 11, the camera component 11 captures the periodontal observation area of ​​the first tooth through the window 22 opened in the working head 20, which can facilitate observation of the health of the teeth such as whether there is tartar. After observing the first tooth, the working head 20 is moved close to the second tooth by holding the moving handle. Since the position of the first tooth is different from that of the second tooth, it is necessary to adjust the angle of the working tip 23 so that the concave surface of the working tip 23 is matched with the second tooth. Specifically, it can be achieved by adjusting the posture of holding the handle. However, it is difficult to find a suitable position by adjusting the posture of holding the handle. When the angle of the working tip 23 is adjusted to make the concave surface of the working tip 23 fit the second tooth, the prior art needs to replace the working head 20 or the working tip 23, and this adjustment method is relatively cumbersome. In the present application, it is only necessary to manually rotate the working head 20 to adjust the angle of the working tip 23 so that the concave surface of the working tip 23 can be flexibly fitted to the second tooth, and the periodontal condition of the second tooth can be observed through the camera assembly 11. The present application provides a method for adjusting the angle of the working tip 23, which is convenient for adapting to different teeth, and the method of adjusting the working tip 23 in the present application is relatively flexible. When the angle of the working tip 23 needs to be adjusted, the user can also use a more comfortable gripping posture to hold it, and the angle of the working tip 23 can be adapted to the specific tooth by rotating the working tip 23, thereby improving the user experience.

[0045] Specifically, the connecting head 21 and the working tip 23 can be integrally formed to form the working head 20 , and the working head 20 abuts against the handle body 10 .

[0046] See also Figure 3 , Figure 4 and Figure 5 As shown, in one embodiment, the connecting head 21 is provided with a plug-in connector 211 , and the working head 20 and the handle body 10 are rotatably connected via the plug-in connector 211 .

[0047] Specifically, after the connector 211 is inserted into the connecting head 21, one end of the connector 211 is in the connecting head 21, and the other end of the connector 211 abuts against the handle body 10, so that the connecting head 21 and the handle body 10 are overlapped through the connector 211. Since the working head 20 and the handle body 10 are overlapped by the connector 211, the working head 20 will not fall off. The handle body 10 is provided with an active area of ​​the connector 211, and the connector 211 can rotate 360 ​​degrees around the axis along the active area. The working head 20 and the handle body 10 are rotatably connected. When the handle body 10 is fixed, the working head 20 can rotate 360 ​​degrees around the axis without falling off.

[0048] See also Figure 3 As shown, in one embodiment, the connector 211 is a pin.

[0049] Specifically, the pin tip is in the shape of a slender column. Optionally, the length range of the pin is (the sum of the through hole depth and the limiting ring groove depth, the limiting ring groove depth).

[0050] In one embodiment, the handle body 10 includes a handle portion 13 and a main body connecting portion 14, and a limiting ring groove 141 is provided at one end of the main body connecting portion 14 facing the working tip 23;

[0051] The connector 21 is provided with a hollow cylinder 212 extending toward one end of the main connecting portion 14, and a through hole 213 is provided on the circumference of the hollow cylinder 212;

[0052] When the hollow cylinder 212 is sleeved on the main connecting portion 14, the position of the through hole 213 corresponds to the position of the limiting ring groove 141;

[0053] The through hole 213 is adapted to the connector 211, so that after the connector 211 is inserted into the through hole 213, one end of the connector 211 overlaps in the through hole 213, and the other end of the connector 211 overlaps in the limiting ring groove 141. After the connector 21 and the main body connection part 14 are overlapped by the connector 211, they can rotate around the axis along the limiting ring groove 141, and the connector 21 and the main body connection part 14 can be rotatably connected.

[0054] Specifically, the working head 20 can rotate 360 ​​degrees along the central axis of the main connecting part 14 through the set limiting ring groove 141, so that the working tip 23 can rotate 360 ​​degrees, which is convenient for the working tip 23 to adapt to teeth in different positions. Especially when it is inconvenient to adjust the posture of holding the handle, the angle of the working tip 23 can be adjusted to adapt to teeth in different positions.

[0055] Specifically, the main connecting part 14 is provided with a column bar on the side facing the working head 20, and a limiting ring groove 141 is provided on the outer side of the column bar; or, the column bar is provided with an annular step protruding outward to form the limiting ring groove 141. The setting method of the limiting ring groove 141 is not limited to the listed methods, and will not be described in detail here. The limiting ring groove 141 serves as an active area for the plug-in component 211 to rotate around the axis.

[0056] Specifically, after the connector 211 is inserted into the through hole 213, one end of the connector 211 is in the through hole 213, and the other end of the connector 211 extends and is inserted into the limiting ring groove 141, so that the working head 20 abuts against the main connecting part 14, and the working head 20 does not fall off. The connector 211 moves in the active area formed by the limiting ring groove 141, so that when the main connecting part 14 is fixed, the working head 20 is rotated to realize the 360-degree rotation of the working tip 23.

[0057] See also Figure 3 and Figure 4 As shown, in one embodiment, there are at least two through holes 213 .

[0058] Preferably, the number of through holes 213 is 4, and the number of pins is 4, and the 4 pins are respectively inserted into the 4 through holes 213. When the working head 20 is rotated, the working head 20 is relatively stable and will not tilt. Of course, the number of through holes 213 is not limited to the preferred 4.

[0059] See also Figure 3 As shown, in one embodiment, a rubber ring 15 is sleeved on one end of the main connecting portion 14 facing the connecting head 21 , one side of the rubber ring 15 abuts against the main connecting portion 14 , and the other side of the rubber ring 15 abuts against the connecting head 21 .

[0060] Specifically, the main connecting part 14 is sleeved with a rubber ring 15, one side of the rubber ring 15 fits the main connecting part 14, and the other side fits the connecting head 21, which plays a damping role when the working head 20 rotates around the axis, making the working head 20 more flexible.

[0061] See also Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, in one embodiment, a collar 24 is further provided on the outer side of the connector 21 , and the collar 24 is sleeved on the connector 21 , and the collar 24 covers the through hole 213 area.

[0062] Specifically, a collar 24 is sleeved on the outer area of ​​the through hole 213 of the connector 21 to prevent the connector 211 inserted in the through hole 213 from falling out, thereby improving the working stability of the working head 20. In addition, the material of the collar 24 can be different from that of the connector 21. In actual operation, when the user needs to rotate the working head 20, the rotatable area can be quickly locked by touching, thereby improving the user experience.

[0063] See also Figure 3 and Figure 6 As shown, in one embodiment, the camera assembly 11 includes a lens and a lens holder 111, and the lens holder 111 is funnel-shaped.

[0064] Specifically, the lens is arranged in the lens bracket 111 , and the lens is used to photograph the periodontal observation area, so as to facilitate the user to understand the periodontal condition of the target teeth; the lens bracket 111 is fixedly connected to the handle body 10 .

[0065] See also Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, in one embodiment, the working head 20 is provided with a receiving tube 25, the window 22 is a through receiving tube 25, one end of the receiving tube 25 extends to connect with the connector 21, and the other end of the receiving tube 25 extends to connect with the working tip 23;

[0066] One end of the lens bracket 111 is fixedly connected to the handle body 10, and the other end of the lens bracket 111 extends into the accommodating tube 25;

[0067] The lens captures the periodontal observation area through the accommodating tube 25 .

[0068] Specifically, the outer diameter of the lens holder 111 at one end of the lens holder 111 extending into the accommodating tube 25 is smaller than the inner diameter of the accommodating tube 25 , and the lens holder 111 and the accommodating tube 25 are in a separated state, so that the lens holder 111 is fixed when the working head 20 rotates.

[0069] See also Figure 3 As shown, in one embodiment, the sensor component 12 passes through the handle body 10 and is connected to a lens disposed in a lens holder 111 at one end, and is connected to an external device at the other end.

[0070] Specifically, the image captured by the lens is transmitted through the sensor component 12.

[0071] It should be noted that when an element is referred to as being "fixed on" or "set on" another component, it can be directly on the other component or indirectly set on the other component; when a component is referred to as being "connected to" another component, it can be directly connected to the other component or indirectly connected to the other component.
