Description

Technical Field

[0001] This utility model relates to the field of dental instrument technology, and in particular to an external root canal preparation machine. Background Technology

[0002] Root canal preparation involves completely removing bacteria-infested portions of the root canal using instruments, revealing its natural, standard shape to facilitate later filling with heated gutta-percha. Currently, root canal treatment relies heavily on visual observation by the dentist, which presents the following problems: it's impossible to continuously monitor the treatment process, it's impossible to save images of the treatment process, and it's impossible to provide real-time live streaming for teaching or expert guidance.

[0003] To address this, relevant improvements have been made in existing technologies. For example, Chinese patent document CN 212089797U discloses an external root canal preparation machine. This device externally mounts a camera on the machine body via a connector. The camera captures image and video information of the root canal treatment process and transmits it to an external terminal via a wireless network, enabling real-time observation, recording, and live streaming.

[0004] However, in existing technologies, the camera and optical fiber are fixedly mounted on an external carrier, making it impossible to adjust the camera's shooting angle according to treatment needs. This limits its adaptability and image acquisition effect in different oral structures or treatment scenarios. Utility Model Content

[0005] This utility model provides an external root canal preparation machine, and the technical problem to be solved is that the shooting angle of the camera can be adjusted as needed.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] An external root canal preparation machine includes a body, a connector, an external carrier, a camera, and an optical fiber. The external carrier is detachably connected to the body via the connector. It also includes a rotating head and an adjustment assembly. The camera and optical fiber are fixedly mounted on the rotating head. The rotating head is located at the front end of the external carrier, with one end hinged to the external carrier. The external carrier has a movable groove. The adjustment assembly is located within the movable groove, with both ends connected to the rotating head and the external carrier, respectively, for driving the rotating head to rotate around the hinge point.

[0008] As a further improvement to the above technical solution:

[0009] In at least one embodiment, the adjusting assembly includes a connecting rod, a screw, and a deflector wheel. The deflector wheel is rotatably mounted on the side wall of the external carrier, with one end extending out of the external carrier. The deflector wheel has a through screw hole along its axis. One end of the screw is inserted into the screw hole and screwed to the deflector wheel. The two ends of the connecting rod are respectively hinged to the end of the rotating head away from the hinge point and the other end of the screw. By driving the deflector wheel to rotate, the screw is driven to translate, and then the rotating head is driven to rotate around the hinge point under the action of the connecting rod.

[0010] Furthermore, in at least one embodiment, the adjusting assembly includes a connecting rod, a screw, and a slider. The screw is rotatably disposed within the movable groove via a support block fixedly connected to the inner wall of the movable groove. The slider is sleeved on the screw and threadedly connected to the screw, and the slider is adapted to the cross-sectional shape of the movable groove. The two ends of the connecting rod are respectively hinged to the end of the rotating head away from the hinge point and the end of the screw. By driving the screw, the slider is driven to translate, and then the rotating head is driven to rotate around the hinge point under the action of the connecting rod.

[0011] Furthermore, in at least one embodiment, a rectangular block is provided along the axis of the end of the screw away from the connecting rod. A control lever is slidably mounted on the rectangular block, with one end extending outward from the outer side of the external carrier. The control lever also has a regular polygonal boss. A regular polygonal slot is formed on the inner wall of the movable groove. A spring is also mounted on the control lever, with both ends of the spring abutting against the support block and the regular polygonal boss, respectively. Under the action of the spring, the regular polygonal boss engages with the regular polygonal slot. This allows the control lever to be locked, preventing unexpected changes in the shooting angle during treatment.

[0012] Compared with the prior art, the present invention achieves at least the following beneficial effects: In the present invention, an external root canal preparation machine has a camera and an optical fiber mounted on a rotating head, and one end of the rotating head is hinged to an external carrier. The hinge angle between the rotating head and the external carrier can be changed by adjusting the components, thereby adjusting the pitch angle of the camera to obtain a clear surgical field image directly facing the root canal orifice.

[0024] To address the shortcomings of existing technologies, such as the inability to adjust the camera's shooting angle according to treatment needs, which limits their adaptability and image acquisition effectiveness in different oral structures or treatment scenarios, the inventors, after careful analysis, discovered that the main reason for these problems in existing external root canal preparation machines is that the camera and optical fiber are fixedly mounted on an external carrier. Based on this analysis, the inventors have made structural improvements to the external root canal preparation machine.

[0025] like Figure 1-7 As shown, an external root canal preparation machine of this utility model includes a body 1, a connector 2, an external carrier 3, a camera 4, an optical fiber 5, a rotating head 6, and an adjustment component 7.

[0026] Example 1

[0027] refer to Figure 1-4 The machine body 1 includes a machine head 11 and a handle 12, which can be integrally formed or detachably connected. The outer wall of the handle 12 has a curved structure for easy gripping. The machine body 1 also includes a connecting base 13, which is connected to an external adjustment panel via a data connection cable for controlling the machine's speed and operating mode.

[0028] The connector 2 has an "S"-shaped structure. Its upper part has a first engaging portion 21 for engaging the handle 12; its lower part has a second engaging portion 22 for engaging the external carrier 3. The first engaging portion 21 contains a flexible gasket 23, which includes a filling sheet 232 and a wear-resistant sheet 233. Auxiliary engaging blocks 231 are provided at both ends to enhance engagement stability. The inner wall of the second engaging portion 22 has multiple adhesive strips 24, and the surface of the adhesive strips 24 has anti-slip textures 241. The edge of the connector 2 also has a flexible positioning block 25 with a fan-shaped cross-section, facilitating the installation and positioning of the external carrier 3.

[0029] The external carrier 3 is installed on the body 1 via the connector 2. The rotating head 6 is located at the front end of the external carrier 3 and is hinged to the external carrier 3 via a hinge shaft. The camera 4 and the optical fiber 5 are fixed on the rotating head 6. The external carrier 3 has a movable groove 31 inside, in which the adjustment component 7 is installed.

[0030] The external carrier 3 is a hollow cuboid or streamlined shell with a hinge seat at its front end for accommodating and hinged to the rotating head 6. The external carrier 3 has a movable groove 31 along its length inside. The movable groove 31 is a through rectangular slot or a groove with guide rails on both sides, used to accommodate and guide the screw 72 in the adjustment assembly 7 to perform linear motion.

[0031] On the side wall of the external carrier 3 corresponding to the actuating wheel 73, a corresponding cylindrical hole is provided. The rotatable support of the operating component and the sealing of the housing can be achieved by installing a miniature bearing or a sealing ring to prevent liquid intrusion.

[0032] In this first embodiment, the adjustment assembly 7 includes a connecting rod 71, a screw 72, and a turntable 73. The turntable 73 is exposed on the side wall of the external carrier 3, and has a screw hole 731 in its middle. One end of the screw 72 is screwed into the screw hole 731, and the other end is hinged to the connecting rod 71. The other end of the connecting rod 71 is hinged to the rotating head 6. When the turntable 73 is rotated, the screw 72 moves axially, which pushes the rotating head 6 to rotate around the hinge point through the connecting rod 71, thereby achieving angle adjustment.

[0033] Camera 4 can be a miniature camera that connects to an external terminal (such as a tablet or computer) via a wireless module to achieve real-time video transmission and storage. Fiber optic cable 5 connects to an internal light source to provide illumination for the shooting area.

[0034] When in use, doctors can adjust the irradiation and shooting angles of camera 4 and fiber optic 5 by adjusting the dial in component 7 according to the patient's oral condition and treatment site, so as to obtain clearer surgical field images and transmit them to the teaching or consultation platform in real time, realizing the visualization, recording and sharing of the treatment process.

[0035] Example 2

[0036] refer to Figure 5-7 The external carrier 3 is mounted on the body 1 via the connector 2. The rotating head 6 is located at the front end of the external carrier 3 and is hinged to the external carrier 3 via a hinge shaft. The camera 4 and the optical fiber 5 are fixed on the rotating head 6. The external carrier 3 has a movable groove 31 inside, in which the adjustment component 7 is installed.

[0037] In this second embodiment, the adjustment component 7 includes a connecting rod 71, a screw 72, a slider 74, a control lever 75, and a spring 76. The screw 72 is rotatably mounted in the movable groove 31 via a support block 32. The slider 74 is sleeved on the screw 72 and threadedly engaged with it. The connecting rod 71 connects the slider 74 and the rotating head 6.

[0038] A rectangular block 721 is provided at one end of the screw 72. The operating lever 75 is sleeved on the rectangular block 721 and can slide axially. The operating lever 75 is provided with a regular polygonal boss 751. Correspondingly, a regular polygonal slot 33 is provided on the inner wall of the movable groove 31. A spring 76 is sleeved on the operating lever 75, with one end abutting against the support block 32 and the other end abutting against the regular polygonal boss 751. Under the action of the spring 76, the boss 751 is engaged in the slot 33 to achieve self-locking.

[0039] When angle adjustment is needed, the doctor presses the control lever 75 inward, compressing the spring 76 and disengaging the polygonal boss 751 from the polygonal slot 33. At this time, although the control lever 75 can slide axially, its internal rectangular hole and the rectangular block 721 at the end of the screw 72 form a sliding key connection, transmitting torque. Rotating the control lever 75 will drive the screw 72 to rotate. After adjustment, releasing the control lever 75 causes the spring 76 to return, pushing the polygonal boss 751 back into the corresponding polygonal slot 33, achieving self-locking and preventing angle changes due to vibration during treatment.

[0040] It should be understood that all the above embodiments are exemplary and not restrictive. Various modifications or variations made by those skilled in the art to the specific embodiments described above under the concept of this utility model should be within the protection scope of this utility model.
