Description

Technical Field

[0001] This utility model relates to the technical field of root canal treatment instruments, and in particular to a shell and base structure that can be arbitrarily tilted and a root canal positioning device. Background Technology

[0002] Measuring root canal length is a crucial step in root canal treatment. It guides precise root canal preparation and filling by determining the working length and apical stop of the root canal. This helps to thoroughly clean infected material from the root canal, protect periapical tissues, and ensure proper root canal filling, thereby improving treatment success rate and patient satisfaction.

[0003] A root canal locator is a dental medical instrument used to help dentists accurately determine the length of root canals during root canal treatment. It determines the length of the root canal by measuring changes in electrical impedance or capacitance in the apical region.

[0004] The main unit of the existing root canal locator is placed directly on the operating table. Doctors can only operate and observe the main unit from the position directly in front of the main unit screen. When the doctor changes position, even if the doctor readjusts the position of the main unit, the main unit cannot be used from different angles. Doctors need to adjust their viewing angle to adapt to the main unit screen. Such root canal locators cannot be arbitrarily oriented, and their flexibility and convenience are low. Utility Model Content

[0005] This invention addresses the technical problem that root canal positioning devices cannot be arbitrarily oriented, resulting in low flexibility and convenience. It provides a shell and base structure for arbitrary orientation, as well as a root canal positioning device.

[0006] This utility model provides a shell and base structure with arbitrary orientation, including a shell and a base. The shell includes a first rotating part with an arc surface, and the base includes a second rotating part with an arc surface. The arc surfaces of the first rotating part and the second rotating part are matched. The first rotating part and / or the second rotating part are provided with a connecting member. The first rotating part and the second rotating part are rotatably connected by the two arc surfaces and the connecting member, so as to realize the arbitrary orientation of the shell and the base.

[0007] Furthermore, the arc surface of the first rotating part is a spherical concave surface, and the arc surface of the second rotating part is a spherical convex surface, or the arc surface of the first rotating part is a spherical convex surface, and the arc surface of the second rotating part is a spherical concave surface.

[0008] Furthermore, the connector is located on the first rotating part, the connector is a magnet, and the material of the second rotating part is iron.

[0009] Furthermore, the connector is provided in multiple parts.

[0010] Furthermore, the second rotating part has a hollow structure.

[0011] Furthermore, the arc surface of the first rotating part and / or the bottom surface of the base are provided with anti-slip components.

[0012] This utility model also provides a root canal positioning device, including the shell and base structure that can be arbitrarily oriented as described in the above solution.

[0013] Furthermore, the outer casing includes an upper casing and a lower casing, the upper casing houses the main unit, and the first rotating part and connecting member are located in the lower casing.

[0014] Furthermore, the lower housing includes a battery cover, which is disposed on the first rotating part.

[0015] Furthermore, it also includes an electrode unit and a measuring unit. The electrode unit includes a conductive wire and a hook body. One end of the conductive wire is electrically connected to the main unit, and the other end is electrically connected to the measuring unit and the hook body.

[0016] The beneficial effects of this utility model are:

[0017] 1. The arbitrary-orientation shell and base structure of this utility model, by respectively providing a first rotating part and a second rotating part with matching arc surfaces on the shell and the base, and providing connecting parts on the first rotating part and / or the second rotating part, allows the shell to rotate at any angle on the base. Firstly, the first and second rotating parts can rotate relative to each other under the action of the two arc surfaces. Secondly, the connecting parts fix the shell to the base, thus stabilizing the shell after rotation. Therefore, this utility model, utilizing the above-mentioned shell and base structure, enables the root canal positioning instrument main unit to be arbitrarily oriented, improving flexibility and convenience.

[0018] 2. By connecting the outer shell to the iron block with a magnet, the outer shell can also be detached from the base, separating the outer shell from the base. This allows the outer shell to be used both as a storage container and as a handheld device, making it more flexible and convenient. Attached Figure Description

[0023] The present invention will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that the embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Moreover, the features in the embodiments of the present invention can be combined with each other without conflict.

[0024] like Figures 1-3 As shown, this utility model provides a shell and base structure with arbitrary tilting direction, including a shell 1 and a base 2. The shell 1 includes a first rotating part 121 with an arc surface, and the base 2 includes a second rotating part 21 with an arc surface. The arc surface of the first rotating part 121 matches the arc surface of the second rotating part 21. A connecting member 3 is provided on the first rotating part 121 and / or the second rotating part 21. The first rotating part 121 and the second rotating part 21 are rotatably connected through the two arc surfaces and the connecting member 3, so as to realize the arbitrary tilting direction of the shell 1 and the base 2.

[0025] In one specific embodiment, the outer shell 1 includes an upper shell 11 and a lower shell 12. The upper shell 11 is the front of the product, and the lower shell 12 is the back of the product. The upper shell 11 and the lower shell 12 are detachably connected around their perimeter by screws.

[0026] The first rotating part 121 is located at the lower end of the lower housing 12, and the lower end of the lower housing 12 is connected to the base 2 through the first rotating part 121. The first rotating part 121 can be integrally formed with the lower housing 12, or it can be glued to the lower housing 12, or it can be installed on the lower housing 12 by screws. The first rotating part 121 has a concave spherical arc surface, that is, the first rotating part 121 forms a circular recess at the lower end of the lower housing 12 for cooperating with the base 2.

[0027] The base 2 includes a second rotating part 21 and a base plate 22. The base plate 22 is basically circular, and a circular groove is formed on the surface of the base plate 22. The second rotating part 21 is adhered to the groove, thereby fixing it to the base plate 22. The second rotating part 21 is a hemispherical iron block with an outwardly convex spherical arc surface. That is, the second rotating part 21 forms a circular protrusion on the base 2 for cooperating with the lower housing 12.

[0028] The spherical concave surface of the first rotating part 121 has the same radius as the spherical convex surface of the second rotating part 21. That is to say, the two can match each other, so that the spherical concave surface of the first rotating part 121 can fit against the spherical convex surface of the second rotating part 21 and rotate on the spherical convex surface of the second rotating part 21, thereby allowing the lower housing 12 to rotate on the base 2, and further allowing the outer shell 1 to rotate on the base 2.

[0029] Furthermore, the lower end of the first rotating part 121 inside the lower housing 12 is evenly provided with a plurality of mounting grooves 122, and the connector 3 is bonded to the mounting grooves 122. The connector 3 is a magnet that can be magnetically attracted to the iron block. Therefore, when the outer shell 1 is placed on the base 2, the magnet is attracted to the iron block, which can fix the outer shell 1 on the base 2 and prevent it from tipping over. This allows the outer shell 1 to be suspended after rotating on the base 2 and maintain its rotated state.

[0030] In summary, the arbitrary-orientation shell and base structure of this utility model, by respectively providing a first rotating part 121 and a second rotating part 21 with matching arc surfaces on the shell 1 and the base 2, and providing a connecting member 3 on the first rotating part 121, allows the shell 1 to rotate at any angle on the base 2. Firstly, the first rotating part 121 and the second rotating part 21 can rotate relative to each other under the cooperation of the two arc surfaces. Secondly, the connecting member 3 secures the shell 1 to the base 2, allowing the shell 1 to stabilize after rotation on the base 2. Therefore, the root canal positioning instrument main unit of this utility model, utilizing the aforementioned shell 1 and base 2 structure, can be arbitrarily oriented, thus improving flexibility and convenience.

[0031] In addition, by connecting the outer shell 1 to the iron block with a magnet, the outer shell 1 can be detached from the base 2, separating the outer shell 1 from the base 2, so that the outer shell 1 can be used both by placing it on the ground and by hand, thus increasing its flexibility and convenience.

[0032] In one specific embodiment, the connector 3 is not limited to a magnet. In this case, the second rotating part 21 does not need to be an iron block. The connector 3 can be other structures, such as a friction pad set between two arc surfaces to provide adjustable friction, or a ball-head locking mechanism to increase friction to fix the position. It can also be achieved by other means other than friction, which will not be elaborated here.

[0033] In one specific embodiment, when the connector 3 is a magnet, the second rotating part 21 is not limited to an iron block, and a magnet that can magnetically attract the connector 3 can also be used, and mutual attraction can be achieved in the same way.

[0034] In one specific embodiment, the connector 3 can be disposed on the second rotating part 21. In this case, as long as the first rotating part 121 has a magnetic structure, mutual adsorption can also be achieved.

[0035] In one specific embodiment, the materials of the connector 3 and the second rotating part 21 can be reversed, that is, the material of the connector 3 is iron and the material of the second rotating part 21 is a magnet, which can also achieve mutual attraction.

[0036] In one specific embodiment, the arc surfaces of the first rotating part 121 and the second rotating part 21 can be reversed, that is, the arc surface of the first rotating part 121 is a spherical convex surface and the arc surface of the second rotating part 21 is a spherical concave surface, which can also achieve the two arc surfaces to fit together for rotation.

[0037] In one specific embodiment, the magnets used in the connector 3 are all small magnets in diameter and volume. Multiple small magnets are evenly arranged on one side of the sphere and tangent to the sphere. This not only makes the structure simple and space utilization high, but also provides strong magnetic force. It is also convenient to adjust the angle with one hand. In addition, compared with large magnets, small magnets have less impact on the circuit. Therefore, using small magnets has greater advantages.

[0038] In one specific embodiment, the second rotating part 21 is a hollow iron structure, that is, the iron block is hollow inside. This can reduce the overall weight of the base 2 while ensuring that it has a certain weight so that the base 2 is not easily moved, making it more convenient to adjust the position of the base 2 or carry it.

[0039] In one specific embodiment, an anti-slip component 4 is bonded to the arc edge of the first rotating part 121 connecting to the second rotating part 21. The anti-slip component 4 is made of silicone and is used to increase resistance, improve the stability of the outer shell 1, and prevent the surface of the iron block from being scratched.

[0040] In one specific embodiment, the bottom surface of the base 2 is also covered with an anti-slip component 4, which can be a silicone pad or, in other embodiments, a suction cup, etc., to improve the stability of the base 2 on the operating table.

[0041] like Figure 4 As shown, this utility model also provides a root canal locator, including a shell and base structure that can be arbitrarily tilted as described above. The root canal locator of this utility model allows for manual angle adjustment to meet the needs of doctors using it in different positions.

[0042] In one specific embodiment, the outer casing 1 houses a main unit for detecting, analyzing, and displaying data. The main unit is fixedly connected to the upper casing 11 and includes modules such as a power supply, screen, processor, and signal generator. The upper casing 11 and the main unit constitute the main unit of the root canal locator. The surface of the upper casing 11 is transparent for displaying information on the screen. Because the product's shape results in a forward-leaning center of gravity, the arrangement of the connecting parts 3 is positioned further back to balance the product's center of gravity and improve its stability.

[0043] In one specific embodiment, the lower housing 12 is fitted with a battery cover 123 by screws on the upper end of the arc surface of the first rotating part 121. The battery cover 123 forms part of the first rotating part 121. When the main unit is fixed on the base 2, the battery cover 123 is located on the second rotating part 21, thereby hiding the battery cover 123 and improving the waterproof performance of the main unit.

[0044] In one specific embodiment, the root canal locator of this utility model further includes an electrode unit 5 for forming a bioelectric circuit and a measuring unit for contacting the tissue inside the root canal for measurement. The electrode unit 5 includes a conductive wire 51 and a hook body 52, and the measuring unit is a file 6. Both the electrode unit 5 and the measuring unit are located outside the main unit and the base 2. Specifically, one end of the conductive wire 51 is electrically connected to the main unit through a socket provided on the side of the outer casing 1, and the other end is split into two, which are electrically connected to the file 6 and the hook body 52 respectively.

[0045] When using the root canal locator, the hook 52 is hung on the patient's lip, and the file 6 is inserted into the patient's root canal. The main unit forms a circuit through the electrode of the hook 52 contacting the oral mucosa and the electrode of the file 6 forming a circuit with the root canal tissue, and monitors the impedance / frequency changes of the file tip in real time. When the file 6 reaches the apical foramen, the electrical signal changes abruptly. The main unit analyzes the data through an algorithm, determines the apical position, and triggers a positioning completion prompt.

[0046] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
