Description

Technical Field

[0001] This utility model relates to the field of dental equipment, and more specifically, to a telescopic root canal preparation machine. Background Technology

[0002] Root canal treatment, also known as endodontic treatment, is a surgical procedure in dentistry to treat pulp necrosis and root infection, primarily used to treat pulpitis and periapical diseases. As one of the core tools in root canal treatment, the root canal preparation machine helps dentists precisely remove infected tissue from inside the tooth and create adequate space for the injection of filling material. Existing root canal preparation machines typically have a fixed working length; however, due to the complex and varied anatomy of the tooth root, especially the significant differences in the length, curvature, and shape of the root canals, fixed-length preparation machines often struggle to adapt to the individual differences of different patients.

[0003] Most current root canal preparation machines use fixed-length heads, which means that the working range of the tool cannot be effectively adjusted when dealing with curved or differently sized root canals. Furthermore, to address different treatment scenarios, traditional root canal preparation machines typically require changing different heads or tools to suit the treatment needs of different patients, increasing operation time and treatment complexity. Utility Model Content

[0004] The purpose of this invention includes, for example, providing a telescopic root canal preparation machine that can be adjusted in shape as needed to match the root canal length and shape of different patients, ensuring better treatment results and saving treatment time.

[0005] The embodiments of this utility model can be implemented as follows:

Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0031] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0032] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0033] In the existing technology, the position of the head assembly 200 of the root canal preparation machine is fixed, and it cannot be adaptively adjusted according to the differences in root canals. When faced with curved root canals or root canals of different lengths, it is impossible to effectively adjust the working range of the tool, resulting in great limitations in its use.

[0034] In view of this, the designers have provided a telescopic root canal preparation machine that can adjust the position of the head assembly 200 as needed to adapt to the treatment of root canals of different shapes, and can reduce the difficulty of operation and save treatment time.

[0035] Please refer to Figures 1-4 This embodiment provides a telescopic root canal preparation machine, including a housing assembly 100 and a head assembly 200, wherein:

[0036] The head assembly 200 is mounted on the housing assembly 100. The head assembly 200 and the housing assembly 100 are slidably engaged in the extension direction of the preset axis 001 to adjust the length of the head assembly 200 extending out of the housing assembly 100. The head assembly 200 is used to mount the working tip 400.

[0037] As described above, the telescopic root canal preparation machine provided in this embodiment operates as follows:

[0038] Before treatment, the position of the head assembly 200 can be adjusted according to the shape of the root canal to be treated. This involves sliding the head assembly 200 relative to the outer shell assembly 100, and changing the length of the head assembly 200 extending beyond the outer shell assembly 100, thus changing the overall length of the preparation machine. During treatment, the head assembly 200 can better access the oral cavity and move within the mouth, facilitating better contact between the working tip 400 mounted on the head assembly 200 and the root canal, thereby improving treatment effectiveness. Because the head assembly 200 can be adjusted according to needs, it can adapt to individual differences among patients, effectively meeting the needs of root canal treatment with varying degrees of curvature, shapes, and lengths, thus having a wide range of applications. Compared to traditional techniques that require changing the head assembly 200 or other tools, this significantly saves treatment time and reduces treatment difficulty.

[0039] The following embodiments illustrate the details of the telescopic root canal preparation machine of this application by way of example.

[0040] Please refer to Figures 1-4 In this embodiment, optionally, the telescopic root canal preparation machine includes a housing assembly 100, a head assembly 200, a drive assembly 300, and a working tip 400. The head assembly 200 is mounted on the housing assembly 100, and the head assembly 200 and the housing assembly 100 are slidably engaged in the extension direction of a preset axis 001 to adjust the length of the head assembly 200 extending beyond the housing assembly 100. The drive assembly 300 is mounted on the housing assembly 100 and is drively connected to the head assembly 200. The working tip 400 is mounted on the head assembly 200. During operation, the drive assembly 300 can input torque via a motor, thereby driving the working tip 400 to rotate through the head assembly 200.

[0041] It should be understood that, since the head assembly 200 can extend and retract relative to the housing assembly 100, thereby changing the position of the head assembly 200 relative to the housing assembly 100, it can adapt to different root canal treatments.

[0042] Please refer to Figures 1-3In this embodiment, optionally, the outer casing assembly 100 includes a housing 110, a rotating member 120, a sliding member 130, and a turntable 140. The rotating member 120 is mounted on the housing 110, and the rotating member 120 and the housing 110 are rotatably engaged around a preset axis 001. The rotating member 120 and the housing 110 are relatively fixed relative to each other in the extending direction of the preset axis 001. The turntable 140 is mounted on the rotating member 120. Applying force to the turntable 140 can drive the rotating member 120 to rotate, making operation effortless. The sliding member 130 is threadedly connected to the rotating member 120, and the sliding member 130 and the housing 110 are relatively fixed relative to each other in the circumferential direction of the preset axis 001. Thus, by rotating the turntable 140, the rotating member 120 is driven to rotate, thereby enabling the sliding member 130 to reciprocate along the extending direction of the preset axis 001. When the head assembly 200 is installed on the slider 130, the head assembly 200 can reciprocate along the extension direction of the preset axis 001 together with the slider 130. Since the rotating part 120 and the slider 130 are threadedly engaged, they have a self-locking function. After the position of the slider 130 is adjusted, the position is stable and it is not easy to freely extend or retract, making it safe and reliable to use.

[0043] Optionally, the housing 110 has an internal mounting channel, the length of which is consistent with the extension direction of the preset axis 001. The peripheral wall of the housing 110 has operation holes 111 communicating with the mounting channel. The number of operation holes 111 can be one or more. When there are multiple operation holes 111, they are evenly spaced around the mounting channel. For example, in this embodiment, there are two operation holes 111.

[0044] Optionally, the rotating component 120 can be inserted into the mounting channel, rotatably engaging with the mounting channel without sliding relative to it along a preset axis 001. For improved flexibility, the rotating component 120 and the housing 110 can be connected via bearings. Additionally, external threads can be provided on a portion of the outer circumferential surface of the rotating component 120. An actuating wheel 140 is fitted onto the rotating component 120, and the actuating wheel 140 and the rotating component 120 can be connected via a spline structure. The outer circumferential surface of the actuating wheel 140 has anti-slip grooves, and a portion of the actuating wheel 140 is exposed within the area enclosed by the operating hole 111. Thus, by applying force to the exposed portion of the actuating wheel 140 in the operating hole 111, the actuating wheel 140 can be rotated, thereby driving the rotating component 120 to rotate, resulting in time-saving and labor-saving operation.

[0045] Since there are two operating holes 111, two fingers can apply force to the dial 140 at the same time, or force can be applied to the dial 140 from the operating holes 111 in different directions, thereby improving the ease of operation.

[0046] Please refer to Figure 3Optionally, the slider 130 is provided with a threaded hole. The slider 130 is inserted into the mounting channel, and the slider 130 is slidably engaged with the mounting channel, and the slider 130 will not rotate relative to the mounting channel. The threaded hole of the slider 130 is screwed into the external thread of the rotating member 120. Thus, when the actuating wheel 140 drives the rotating member 120 to rotate, the slider 130 can reciprocate relative to the housing 110 along the extension direction of the preset axis 001.

[0047] In this embodiment, optionally, the head assembly 200 can be welded, bonded, or snap-fitted to the sliding member 130, as long as the head assembly 200 and the sliding member 130 are relatively fixed.

[0048] Please refer to Figures 3-4 For example, in this embodiment, the head assembly 200 includes a head housing 210 and a clamping member 220 installed within the connector housing. The clamping member 220 can be a sleeve structure, and is rotatably connected to the head housing 210. A first bevel gear 230 can be integrated into the outer peripheral surface of the clamping member 220. The working tip 400 is inserted into the clamping member 220, and can be clamped by the clamping member 220, thereby rotating together with the clamping member 220.

[0049] In this embodiment, optionally, the drive assembly 300 includes a drive housing 310, a gear transmission unit 320, an output shaft 330, and a transmission shaft 340, with the drive housing 310 fixedly connected to the housing 110. The gear transmission unit 320, output shaft 330, and transmission shaft 340 are all mounted on the drive housing 310. The gear transmission unit 320, output shaft 330, and transmission shaft 340 are sequentially connected for transmission. After the gear transmission unit 320 inputs torque, it can output torque from the output shaft 330, driving the transmission shaft 340 to rotate. A second bevel gear 350 is integrated at the end of the transmission shaft 340. The second bevel gear 350 meshes with the first bevel gear 230, thereby driving the clamping member 220 to rotate and achieving torque output.

[0050] Optionally, the output shaft 330 is provided with a mounting hole, and the transmission shaft 340 is inserted into the mounting hole. The transmission shaft 340 and the mounting hole are slidably engaged in the extension direction of the preset axis 001, and the transmission shaft 340 and the mounting hole are relatively fixed in the circumferential direction of the preset axis 001.

[0051] Meanwhile, the drive shaft 340 can be rotatably connected to the sliding member 130 or the head housing 210, and the drive shaft 340 and the sliding member 130 or the head housing 210 are relatively fixed in the extension direction of the preset axis 001. In this way, when the head housing 210 slides along the extension direction of the preset axis 001 with the sliding member 130, it can drive the drive shaft 340 to slide together, thereby ensuring that the first bevel gear 230 on the connecting shaft is always engaged with the second bevel gear 350 in the head housing 210 to realize power transmission.

[0052] In some embodiments, the rotating member 120 may be omitted, or the rotating member 120 and the housing 110 may be integrated into one structure. In this case, the sliding member 130 is threadedly connected to the housing 110 or the rotating member 120, and the axial position of the machine head assembly 200 can be adjusted by rotating the machine head assembly 200.

[0053] The telescopic root canal preparation machine provided in this embodiment can adjust the position of the head assembly 200 relative to the outer shell assembly 100 as needed according to the treatment conditions of different patients, thereby adjusting the length of the head assembly 200 extending out of the outer shell assembly 100. This expands the working range of the working tip 400 installed on the head assembly 200, thus adapting to the individual differences of different patients and effectively meeting the needs of root canal treatment with different degrees of curvature, different shapes and different lengths, making it widely applicable.

[0054] 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 variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
