Description

Technical Field

[0001] The present invention relates to the technical field of dental correction, and in particular to a shell-shaped dental instrument and a dental instrument assembly comprising the shell-shaped dental instrument. Background Art

[0002] When using shell-shaped dental appliances for dental treatment (for example, orthodontic treatment or orthognathic treatment), it is sometimes necessary to add external accessories to the shell-shaped dental appliances to assist in the treatment, such as bimaxillary plates, brackets, tongue buttons, flat guides, and jaw pads. These external accessories are processed separately and then fixed to the shell-shaped dental appliances by gluing, welding, mechanical connection, etc.

[0003] Since these external accessories may be standard parts with a mounting surface of a predetermined standard shape, or they may be non-standard parts, the mounting surface needs to be processed according to the shape of the shell-like dental instrument at the installation position. Therefore, the strength of these external accessories installed on the shell-like dental instrument is greatly related to the geometric shape of the joint surface between the external accessories and the shell-like dental instrument.

[0004] Chinese patent application CN208725922U discloses a shell-shaped dental instrument and its shell-shaped main body, wherein the dental instrument includes a shell-shaped main body, on which an accessory mounting area is formed, and the contour of the outer surface of the accessory mounting area has a standard geometric shape, which basically matches the contour of the external accessory mounting surface, so that the external accessory can be fixed on the outer surface of the accessory mounting area through its mounting surface. This solution can solve the problem of connection and fixation between the external accessory and the dental instrument, but in actual operation, the operator faces other problems. For example, multiple external accessories may be installed on the accessory mounting area of ​​the dental instrument at the same time, and the multiple external accessories are of different types and need to be installed in specific positions, or the installation of the external accessories needs to meet the requirements of facing a specific direction. In these cases, the operator can easily make an operation error, resulting in the external accessories failing to achieve the expected effect. Summary of the invention

[0005] The technical problem to be solved by the present invention is to overcome the defect in the prior art that operators are prone to operating errors resulting in the failure of external accessories to achieve the expected effect, and to provide a shell-shaped dental instrument and a dental instrument assembly containing the same.

[0006] The present invention solves the above technical problems through the following technical solutions:

[0007] A shell-shaped dental instrument comprises a shell-shaped main body, on which an accessory installation area is formed; the characteristic is that a mark is provided on the shell-shaped main body at a position corresponding to the accessory installation area, and the feature of the mark is used to indicate at least one of the type, installation position and installation direction of an external accessory installed on the accessory installation area.

[0008] In the present embodiment, an accessory installation area is formed on the shell-shaped body of the shell-shaped dental instrument, and the accessory installation area is used to install external accessories. By setting a mark at a position on the shell-shaped body corresponding to the accessory installation area, the characteristics of the mark can indicate at least one of the type, installation position and installation direction of the external accessory installed in the accessory installation area. When installing the external accessory, the operator only needs to refer to the characteristics of the mark to obtain the indication information brought by the mark. According to the indication information, the correct type of external accessory can be selected, or the external accessory can be installed in the correct position or in the correct direction, so as to avoid to the greatest extent the operator's mistakes in operation that cause the external accessory to fail to achieve the expected effect.

[0009] Furthermore, the features of the marks corresponding to at least two types of external accessories are different.

[0010] In this solution, when at least two types of external accessories need to be installed on the accessory installation area, by setting the features of the corresponding marks to be different, different types of external accessories can be correctly installed.

[0011] Furthermore, the number of the marks is the same as the number of external accessories installed on the accessory installation area, and the characteristics of any two of the marks are different.

[0012] In the present solution, through this setting, when multiple external accessories need to be installed on the accessory installation area, the number of marks set at the accessory installation area is the same as the number of installed external accessories, and the characteristics of each mark are different, thereby avoiding the presence of multiple marks to mislead the operator.

[0013] Furthermore, the mark corresponds to different external accessories installed on the accessory installation area and has outer contours of different shapes.

[0014] In this solution, the location where the external accessory needs to be installed can be obtained by marking the location on the accessory installation area, and then by setting the outer contour of the mark to different shapes, the operator can identify the type of external accessory that needs to be installed based on the different shapes of the outer contour, making it easier to identify the operation.

[0015] Furthermore, the outer contour of the mark extends at least along a first direction at the location of the accessory installation area, and the width dimension of the outer contour of the mark along the first direction gradually changes.

[0016] In the present solution, the location where the external accessory needs to be installed can be obtained by marking the setting position at the accessory installation area, and then the outer contour of the mark is designed to have the function of indicating direction. The operator can clearly know the direction in which the external accessory needs to be installed through the mark, and it is also easier to identify the operation.

[0017] Furthermore, the mark is disposed at a non-center of the accessory installation area, and the direction from the mark to the center of the accessory installation area corresponds to the installation direction of the external accessory.

[0018] In this solution, the mark is located at a non-center of the accessory installation area, so that the mark has a certain direction to the center of the accessory installation area, which corresponds to the installation direction of the external accessory. When the operator knows the position of the mark, he can know the direction in which the external accessory is to be installed, and the instructions are simpler and clearer.

[0019] Furthermore, the mark is an arrow representing a specific direction, and the direction represented by the arrow corresponds to the installation direction of the external accessory; or, the mark is a linear structure representing a specific direction, and at least one of the directions represented by the linear structure corresponds to the installation direction of the external accessory.

[0020] In this solution, the mark directly uses an arrow to represent a specific direction, and the specific direction pointed by the arrow corresponds to the installation direction of the external accessory. Alternatively, the mark uses a linear structure to represent a specific direction, and at least one of the directions represented by the linear structure corresponds to the installation direction of the external accessory. After seeing the mark, the operator can clearly determine the direction in which the external accessory needs to be installed, and the instruction is more direct and clear.

[0021] Furthermore, a non-slip pad is provided on the surface of the accessory installation area, and the non-slip pad at least covers the area of ​​the accessory installation area for installing external accessories.

[0022] In the present solution, an anti-slip pad is provided on the surface of the accessory installation area, and the specific area covered by the anti-slip pad is provided, so that when installing external accessories on the accessory installation area, sliding and shifting of the external accessories relative to the shell-shaped main body during operation can be avoided, thereby ensuring the accuracy and quality of the installation of the external accessories.

[0023] Furthermore, the mark is set at the location of the accessory installation area by laser marking or printing.

[0024] In this solution, a mark is set at the location of the accessory installation area by laser marking or printing, so that the mark is only formed on the surface of the corresponding position, avoiding structural changes to the shell-like body or the accessory installation area, and further avoiding the impact of installing foreign accessories on the accessory installation area.

[0025] Furthermore, the mark is arranged on the surface of the accessory installation area, and the outer contour of the mark is consistent with the outer contour of the accessory installation area.

[0026] In this solution, when the mark is a first protrusion or a first groove, the mark is set on the surface of the accessory installation area, and the outer contour of the mark can be consistent with the outer contour of the accessory installation area. The contour of the accessory installation area can be directly used as a mark to indicate the type of external accessories that need to be installed and the installation direction, which is more reasonable in structure.

[0027] Further, the mark is a first protrusion or a first depression having a peripheral contour.

[0028] In this solution, by providing a mark at the location of the accessory installation area by providing a first protrusion or a first groove, the indication feature of the mark is more obvious and more convenient for operators to observe. At the same time, in this way, when an external accessory is installed on the accessory installation area, the cooperation between the mark and the external accessory can be used to further locate the external accessory, so as to completely avoid the occurrence of wrong installation of the external accessory.

[0029] A dental instrument assembly, characterized in that the dental instrument assembly comprises:

[0030] A shell-shaped dental device as described above;

[0031] The external accessory has a second depression on its mounting surface that cooperates with the first protrusion along a specific direction, or the external accessory has a second protrusion on its mounting surface that cooperates with the first depression along a specific direction.

[0032] In the present solution, when the mark is a first protrusion or a first groove, the mounting surface of the external accessory has a second groove that cooperates with the first protrusion, or the mounting surface of the external accessory has a second protrusion that cooperates with the first groove. When the external accessory is installed in the accessory mounting area, the problem of insufficient connection strength is avoided. At the same time, the matching connection between the mark and the external accessory is utilized to realize the positioning of the external accessory relative to the accessory mounting area, and the matching between the external accessory and the accessory mounting area is designed to prevent mistakes in assembly of the two.

[0033] Furthermore, the first protrusion is two columnar structures arranged at intervals, the radial dimensions of the two columnar structures are different, and the second recess is tangentially matched with the two columnar structures at the same time.

[0034] In the present solution, two column structures with different radial dimensions are provided so that when the second depression is engaged with the first protrusion, the second depression can be tangentially matched with the two column structures at the same time, so that external accessories can only be installed on the accessory installation area along a specific direction, and assembly errors of the two are completely avoided through the fool-proof design of the physical structure.

[0035] Furthermore, the outer contour of the first protrusion is a cam-shaped columnar structure, and the inner wall contour of the second recess cooperates with the outer contour of the first protrusion.

[0036] In this solution, by setting the outer contour of the first protrusion and the inner wall contour of the second groove to a cam shape, the two can only be connected to each other in a specific direction. Similarly, the fool-proof design of the physical structure is used to completely avoid assembly errors between external accessories and the accessory installation area.

[0037] A dental instrument assembly is characterized in that the dental instrument assembly comprises: the shell-shaped dental instrument as described above; and an external accessory, wherein the external accessory is installed at a position corresponding to the accessory installation area.

[0038] In this solution, the dental instrument assembly includes the shell-shaped dental instrument as described above, and the marked features can be used to indicate the type of external accessories that need to be installed as well as the installation position and installation direction, effectively solving the defect in the prior art that operators are prone to operating errors, resulting in the external accessories failing to achieve the expected effect.

[0039] The positive and progressive effects of the present invention are:

[0040] An accessory installation area is formed on the shell-shaped body of the shell-shaped dental instrument, and the accessory installation area is used to install external accessories. By setting a mark at a position on the shell-shaped body corresponding to the accessory installation area, the characteristics of the mark can indicate at least one of the type, installation position and installation direction of the external accessory installed in the accessory installation area. When installing the external accessory, the operator only needs to refer to the characteristics of the mark to obtain the indication information brought by the mark. According to the indication information, the correct type of external accessory can be selected, or the external accessory can be installed in the correct position or in the correct direction, so as to avoid to the greatest extent the operator's mistakes in operation that cause the external accessory to fail to achieve the expected effect.

In the description of the present invention, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0061] Example 1

[0062] This embodiment provides a dental instrument assembly 10, such as Figure 1 , Figure 2 and Figure 3 As shown, the dental instrument assembly 10 includes a shell-shaped dental instrument 100 and an external attachment 200. The main part of the shell-shaped dental instrument 100 is a shell-shaped body 110, and the external attachment 200 is fixed on the shell-shaped body 110. The shell-shaped body 110 is formed with an attachment installation area 111, and the contour of the outer surface of the attachment installation area 111 has a standard geometric shape. The external attachment 200 is fixed to the attachment installation area 111 of the shell-shaped body 110 through its installation surface. The specific fixing method can be any method existing in the prior art, such as pasting, welding, mechanical connection, etc. In addition, the external attachment 200 can be any element that needs to be installed on the shell-shaped dental instrument 100 in the field of dental orthodontics technology, such as a flat guide plate, a traction button, a traction hook, an indicator, etc.

[0063] In this embodiment, the contour of the outer surface of the accessory mounting area 111 has a standard geometric shape, which can be better used to install the external accessory 200. However, in other embodiments, the contour of the outer surface of the accessory mounting area 111 may not have a standard geometric shape. For example, the external accessory 200 is installed on the surface of the shell-like body 110, and the installation location can be called the accessory mounting area 111.

[0064] Further, such as Figure 2As shown, the shell-like body 110 is provided with a mark 120 on the surface of the accessory installation area 111. The outer contour of the mark 120 is circular. The circular mark 120 can be used to indicate the installation position of the external accessory 200 installed in the accessory installation area 111. In other words, the position of the circular mark 120 on the accessory installation area 111 is the installation position of the external accessory 200. Through this arrangement, when installing the external accessory 200, the operator can correctly install it according to the indication information brought by the mark 120. For example, the operator only needs to refer to the position of the mark 120 on the accessory installation area 111 to install the external accessory 200 in the correct position, so as to avoid to the greatest extent that the operator installs the external accessory 200 in the wrong position during operation, resulting in the external accessory 200 failing to achieve the expected effect.

[0065] The reason why the mark 120 is set on the surface of the accessory installation area 111 is that the external accessory 200 is installed on the accessory installation area 111. Therefore, compared with setting the mark 120 on other parts of the shell body 110, setting the mark 120 directly on the surface of the accessory installation area 111 can avoid the damage that the mark 120 may cause to other parts of the shell body 110, and avoid the risk that the matching degree between the shell body 110 and the user's teeth may be reduced. However, in other embodiments, the mark 120 can be set near the accessory installation area 111, that is, it can also be set on the surface of the shell body 110, as long as the mark 120 can be used to provide instruction information to the operator.

[0066] Furthermore, if there are multiple external accessories 200 to be installed on the accessory installation area 111, the number of marks 120 on the accessory installation area 111 is also multiple, that is, the number of marks 120 on the accessory installation area 111 is the same as the number of external accessories 200 to be installed, and the positions indicated by any two marks 120 are different. The operator can install multiple external accessories 200 at the same time according to the positions of multiple marks 120, which is more convenient. For example, three external accessories 200 need to be installed on the shell-shaped dental instrument 100, of which two external accessories 200 are traction hooks with different installation angles, and one external accessory 200 is a traction buckle, and the features indicated by the corresponding marks 120 of the three external accessories 200 can be different.

[0067] Furthermore, an anti-slip pad (not shown in the figure) is provided on the surface of the accessory installation area 111, and the anti-slip pad can at least cover the area on the accessory installation area 111 for installing the external accessory 200, so that when the external accessory 200 is installed on the accessory installation area 111, it can avoid sliding and shifting of the external accessory 200 relative to the shell-like body 110 during operation, thereby ensuring the accuracy and quality of the installation of the external accessory 200.

[0068] In this embodiment, the mark 120 can be directly set on the surface of the accessory installation area 111 by laser marking or printing, or the mark 120 can be set as a first protrusion or a first depression with a circular contour on the surface of the accessory installation area 111. Specifically, by laser marking or printing, the mark 120 can be formed only on the surface of the accessory installation area 111, avoiding structural changes to the accessory installation area 111, thereby avoiding affecting the installation of the external accessory 200 on the accessory installation area 111; however, by setting the mark 120 as a first protrusion or a first depression with a circular contour, the indication feature of the mark 120 can be made more obvious, which is more convenient for the operator to observe. At the same time, in this way, when the external accessory 200 is installed on the accessory installation area 111, the cooperation between the mark 120 and the external accessory 200 can be used to further position the external accessory 200, so as to completely avoid the external accessory 200 from being installed incorrectly.

[0069] Regardless of the method used to form the mark 120 on the accessory installation area 111, the mark 120 can be used to indicate the position where the operator installs the external accessory 200. However, it should be noted that when the mark 120 is set as a first protrusion or a first depression with a circular contour, the mark 120 can be formed integrally with the accessory installation area 111. Specifically, when the mark 120 is a first protrusion with a circular contour, since the accessory installation area 111 is also a protrusion structure on the surface of the shell-like body 110, the mark 120 can be integrally formed with the accessory installation area 111 during processing. Alternatively, when the mark 120 is a first depression with a circular contour, the mark 120 can also be directly processed on the accessory installation area 111, so that the mark 120 and the accessory installation area 111 are integrally formed.

[0070] In addition, when the mark 120 is set to a first protrusion or a first depression with a circular contour, the corresponding installation surface of the external accessory 200 should also have a second depression that cooperates with the first protrusion, or a second protrusion that cooperates with the first depression. When the external accessory 200 is installed in the accessory installation area 111, the problem of insufficient connection strength can be avoided. At the same time, the matching connection between the mark 120 and the external accessory 200 can be used to realize the positioning of the external accessory 200 relative to the accessory installation area 111.

[0071] This embodiment also provides an auxiliary operation method to cooperate with the mark 120 on the shell-shaped dental instrument 100 to achieve accurate installation of the external attachment 200. Specifically, each shell-shaped dental instrument 100 has an ID identification feature, which can be a two-dimensional code or serial number on the shell-shaped dental instrument 100, or a two-dimensional code or serial number on the flow work order, or a two-dimensional code or serial number formed on the film before demolding. When installing the external attachment 200, first use an information acquisition device (for example, a scanning device or manual input) to obtain the ID identification feature of the semi-finished shell-shaped dental instrument 100, and display the type of the external attachment 200 and its installation position and installation direction on the display device (for example, a display screen) according to the pre-designed scheme in the system to help the operator accurately identify it. In this way, the operator can install the external attachment 200 by observing the screen and combining the mark 120 on the shell-shaped dental instrument 100, and can quickly adjust the operation during the installation process, and ensure that the quality of the final installation of the external attachment 200 reaches the best level.

[0072] In addition, after the ID identification feature of the semi-finished shell-shaped dental instrument 100 is obtained by the information acquisition device, the corresponding external accessory 200 display in the system can also automatically remind the type of external accessory 200 to be selected. For example, the corresponding model of the external accessory 200 box is opened through the control setting, and the rest are closed, or the corresponding model of the external accessory 200 box flashes a warning light, etc.

[0073] Furthermore, a display device may not be provided, and only a collection and identification device (for example, a camera) is required to detect the type of the external accessory 200 and its installation position and installation direction. The collection and identification device needs to be able to quickly and accurately detect whether the type of the external accessory 200 and its installation position and installation direction are correct, and transmit the collected data to the control system. The control system uses the collected data to calculate in real time whether the external accessory 200 is in the correct position and correct direction. When the actual installation position or installation direction deviates from the correct position or correct direction, the system can respond quickly and prompt the operator to correct the error to ensure that the external accessory 200 is installed in the correct position and correct direction.

[0074] Example 2

[0075] This embodiment provides a dental instrument assembly 10, whose structure and assembly are substantially the same as those of the dental instrument assembly 10 provided in Embodiment 1, that is, the dental instrument assembly 10 also includes a shell-shaped dental instrument 100 and an external attachment 200, the shell-shaped dental instrument 100 includes a shell-shaped main body 110, and the external attachment 200 is fixed on the shell-shaped main body 110. The shell-shaped main body 110 is formed with an attachment installation area 111, and the external attachment 200 is fixed on the attachment installation area 111 of the shell-shaped main body 110 through its installation surface.

[0076] The difference is that, in this embodiment, Figure 4 As shown, three accessory installation areas 111 are formed on the shell-like main body 110, and a mark 120 is set on the surface of each accessory installation area 111, wherein the outer contour of the mark 120 on the accessory installation areas 111 at both ends is circular, and the outer contour of the mark 120 on the middle accessory installation area 111 is runway-shaped, and the marks 120 set on the surface of the three accessory installation areas 111 can be used to indicate the installation position of the external accessories 200 installed in each accessory installation area 111.

[0077] like Figure 4As shown, the mark 120 on the accessory installation area 111 located on the left is set at the center of the accessory installation area 111. Therefore, the mark 120 on the accessory installation area 111 is only used to indicate the installation position of the external accessory 200 installed on the accessory installation area 111; the mark 120 on the accessory installation area 111 located on the right is set at the edge of the accessory installation area 111. Therefore, the mark 120 on the accessory installation area 111 can be used not only to indicate the installation position of the external accessory 200 installed on the accessory installation area 111, but also to indicate the installation direction of the external accessory 200 installed on the accessory installation area 111. The specific method is that the direction from the center of the accessory installation area 111 to the mark 120 on the accessory installation area 111 corresponds to the installation direction of the external accessory 200. When the operator knows the position of the mark 120, The direction in which the external accessory 200 is to be installed is known, and the indication is clearer; the outer contour of the mark 120 located on the middle accessory installation area 111 is in the shape of a runway. Therefore, the mark 120 on the accessory installation area 111 can be used not only to indicate the installation position of the external accessory 200 installed on the accessory installation area 111, but also to indicate the specific type of the external accessory 200 installed on the accessory installation area 111. The specific method is that the mark 120 has outer contours of different shapes corresponding to different external accessories 200 installed on the accessory installation area 111. For example, when the outer contour is circular, it represents one external accessory 200, and when the outer contour is in the shape of a runway, it represents another external accessory 200. When the operator knows the specific shape of the outer contour of the mark 120, he can know the type of external accessory 200 that needs to be installed at the position, and the operation is simple and convenient.

[0078] In this embodiment, one external accessory 200 is installed on each of the three accessory installation areas 111, so there is also one mark 120 on each accessory installation area 111. However, as in the first embodiment, if there are multiple external accessories 200 to be installed on one accessory installation area 111, the number of marks 120 on the accessory installation area 111 is also multiple, that is, the number of marks 120 on the accessory installation area 111 is the same as the number of external accessories 200 to be installed, and the types, installation positions or installation directions of the external accessories 200 indicated by any two marks 120 are different. The operator can install multiple external accessories 200 at the same time according to the positions of the multiple marks 120, which is more convenient and will not cause confusion. It should be noted that, in this case, each external accessory 200 corresponds to a different type, and the different types result in different installation positions and directions. However, in actual situations, there may be only two types of multiple external accessories 200, and the installation positions of each type of external accessories 200 may be different, but the installation directions may be the same. In this case, the features of the corresponding marks 120 of the two types of external accessories 200 are different, so as to mainly distinguish the installation of different types of external accessories 200, without distinguishing the installation of the same type of external accessories 200.

[0079] Example 3

[0080] This embodiment provides a dental instrument assembly 10, whose structure and assembly are roughly the same as the structure and assembly of the dental instrument assembly 10 provided in Example 1 and Example 2, that is, the dental instrument assembly 10 also includes a shell-shaped dental instrument 100 and an external attachment 200, the shell-shaped dental instrument 100 includes a shell-shaped main body 110, and the external attachment 200 is fixed on the shell-shaped main body 110.

[0081] The difference is that, in this embodiment, Figure 5 As shown, two accessory installation areas 111 are formed on the shell body 110, and a mark 120 is set at the location of each accessory installation area 111. However, the mark 120 is set at the outer periphery of the corresponding accessory installation area 111, that is, it is set at the position of the shell body 110 close to the accessory installation area 111. Specifically, as shown in FIG. Figure 5As shown, the two marks 120 are both located on the left side of the corresponding accessory installation area 111, wherein the outer contour of the mark 120 corresponding to the accessory installation area 111 located on the right side is circular, which is the same as Example 2. The direction from the center of the accessory installation area 111 to the mark 120 on the accessory installation area 111 corresponds to the installation direction of the external accessory 200. When the operator knows the position of the mark 120, he can know the direction in which the external accessory 200 is to be installed; the outer contour of the mark 120 corresponding to the accessory installation area 111 located on the left side is runway-shaped, which is the same as Example 2, and can also be used to indicate the specific type of the external accessory 200 installed on the accessory installation area 111. The specific method can refer to Example 2.

[0082] In this embodiment, the mark 120 is set on the periphery of the accessory installation area 111 to prevent the mark 120 from damaging the surface of the accessory installation area 111 and to prevent the installation of an external accessory 200 on the accessory installation area 111 from causing a reduction in connection strength.

[0083] However, in a similar scheme, the mark 120 can be set across the accessory installation area 111, that is, part of the mark 120 is located inside the accessory installation area 111, and part of the mark 120 is located outside the accessory installation area 111, as long as it does not affect the mark 120 from performing its indication function and does not affect the installation of the external accessory 200.

[0084] Example 4

[0085] This embodiment provides a dental instrument assembly 10, whose structure and assembly are substantially the same as those of the dental instrument assembly 10 provided in Embodiment 1 and Embodiment 2, that is, the dental instrument assembly 10 also includes a shell-shaped dental instrument 100 and an external attachment 200, the shell-shaped dental instrument 100 includes a shell-shaped main body 110, and the external attachment 200 is fixed on the shell-shaped main body 110. The shell-shaped main body 110 is formed with an attachment installation area 111, and the external attachment 200 is fixed on the attachment installation area 111 of the shell-shaped main body 110 through its installation surface.

[0086] The difference is that, in this embodiment, Figure 6As shown, an accessory installation area 111 is formed on the shell-like body 110, and a mark 120 is arranged on the surface of the accessory installation area 111. The outer contours of the accessory installation area 111 and the mark 120 are the same, both in the shape of arrows. The accessory installation area 111 and the mark 120 located above it can be set separately, or as described in Example 1, the accessory installation area 111 and the mark 120 located above it can be set by integral molding. In addition, as shown in Examples 1 and 2, the accessory installation area 111 can be a circular area set on the shell-like body 110, and the mark 120 located above it can be set on the surface of the accessory installation area 111 by laser marking or printing.

[0087] By directly using an arrow representing a specific direction as the mark 120, the specific direction pointed by the arrow corresponds to the installation direction of the external accessory 200. The operator can clearly determine the direction in which the external accessory 200 needs to be installed by looking at the mark 120, and the instruction is more direct and clear.

[0088] In addition, there is a similar design in which the mark 120 is directly set to a linear structure having a specific direction, and at least one of the directions represented by the linear structure corresponds to the installation direction of the external accessory 200. For example, when the mark 120 is a line segment, the two ends of the line segment extend in opposite directions, and the extension directions of the two ends of the line are the directions represented by it, and at least one direction is the installation direction of the external accessory 200. In this case, the operator can clearly get the direction in which the external accessory 200 needs to be installed by seeing the mark 120, and the indication is also clear. Exemplarily, if the mark 120 is used to indicate the installation of the double-wing lingual buckle, since the double-wing lingual buckle structure has two lingual buckles arranged along the same straight line, only one line segment is needed to indicate its installation, and there is no need to mark the arrows using specific directions. The arrow and the line segment can also be used as the mark 120 indicating the type of the external accessory 200 at the same time. For example, the ordinary traction hook is represented by an arrow, while the traction hook of the double wing is represented by a line segment.

[0089] Example 5

[0090] This embodiment provides a dental instrument assembly 10, whose structure and assembly are basically the same as those of the fourth embodiment, except that this embodiment provides another mark 120 with a direction indication, such as Figure 7As shown, two accessory installation areas 111 are formed on the shell-like body 110, and marks 120 are set on the surfaces of the two accessory installation areas 111, wherein the outer contour of one mark 120 is a trapezoid, and the outer contour of the other mark 120 is similar to a crescent shape, and the common point is that the outer contour of the mark 120 on the corresponding accessory installation area 111 extends in one direction, and the width dimension of the outer contour of the mark 120 along the direction gradually changes, and the change in the dimension enables the mark 120 to have the function of indicating the direction. It should be noted that in other embodiments, the outer contour of the mark 120 on the accessory installation area 111 can be designed as needed, so that the mark 120 has the function of indicating the type, installation position and installation direction of the external accessory 200 to be installed.

[0091] Example 6

[0092] This embodiment provides a dental instrument assembly 10, whose structure and assembly are basically the same as those of Embodiment 4 and Embodiment 5, except that the mark 120 provided in this embodiment is a first protrusion with an outer contour, and the mounting surface of the external attachment 200 has a second recess that cooperates with the first protrusion along a specific direction. It should be noted that the specific direction refers to the direction in which the first protrusion and the second recess cooperate with each other, and the first protrusion and the second recess can only cooperate with each other along this direction.

[0093] like Figure 8 As shown, the outer contour of the first protrusion is a closed shape formed by two semicircular arcs and two straight lines, and a second depression is provided on the surface of the external accessory 200 close to the first protrusion, so that when the external accessory 200 abuts against the accessory installation area 111 or the shell-shaped body 110, the first protrusion can cooperate with the second depression. Through this arrangement, the position of the first protrusion can be used to indicate the position where the external accessory 200 needs to be installed, and the outer contour of the first protrusion can be used to indicate the direction in which the external accessory 200 is installed. At the same time, this method can also use the cooperation between the mark 120 and the external accessory 200 to further position the external accessory 200, so as to completely avoid the external accessory 200 from being installed incorrectly.

[0094] Similar designs, such as Fig. 9 As shown, the bottom of the external attachment 200 is a second depression, and the inner wall profile of the second depression is a cam shape, and the corresponding outer contour of the mark 120 is Fig.10 or Fig.11 As shown in Fig.10There are two marks 120 corresponding to the second recess, and the two marks 120 are column structures arranged at intervals, and the radial dimensions of the two column structures are different. The two column structures are tangentially matched with both ends of the second recess at the same time. By setting two column structures with different radial dimensions, when the second recess is engaged with the first protrusion, the second recess can be tangentially matched with the two column structures at the same time, so that the external accessory 200 can only be installed on the accessory installation area 111 along a specific direction, and the fool-proof design of the physical structure completely avoids assembly errors between the two. Fig.11 The middle mark 120 is a first protrusion, and the outer contour of the first protrusion is the same as the inner wall contour of the second recess, which is also a cam shape. Therefore, the first protrusion can be fully matched with the second recess, so that the two can only be connected to each other in a specific direction. The fool-proof design of the physical structure is also used to completely avoid assembly errors between the external accessory 200 and the accessory installation area 111.

[0095] In addition, in other embodiments, the mark 120 may also be set as a first recess having a peripheral contour, and the mounting surface of the external accessory 200 may have a second protrusion that cooperates with the first recess.

[0096] It should be noted that when the mark 120 is a first protrusion with an outer contour, and the outer contours of the accessory installation area 111 and the mark 120 are the same, at this time, if the second depression of the external accessory 200 cooperates with the first protrusion, it may cause the size of the external accessory 200 to be larger than the size of the accessory installation area 111. When the external accessory 200 is installed, a gap may be formed between the external accessory 200 and the surface of the shell-like body 110, and the thickness of the gap is the thickness of the accessory installation area 111. In this case, the depth of the second depression can be set slightly larger than the height of the first protrusion, so that after the second depression and the first protrusion cooperate with each other, the second depression can also wrap the accessory installation, thereby avoiding the formation of a gap between the external accessory 200 and the surface of the shell-like body 110 after the external accessory 200 is installed.

Those skilled in the art may make various changes or modifications to these embodiments without departing from the principles and essence of the present invention, but these changes and modifications all fall within the protection scope of the present invention.
