Description

Technical Field

[0001] The invention relates to the technical field of oral orthodontic appliances, and in particular to a buccal tube. Background Art

[0002] The buccal tube is an important component of the fixed orthodontic appliance, which consists of a hollow tube, a traction hook and a base plate. In general, the buccal tube is directly pasted or fixed on the molar tooth surface by a band, and the correction arch wire passes through the hollow tube of the buccal tube, and the buccal tube can play the role of fixing the arch wire. The buccal tube is provided with a traction hook for hanging rubber rings or tension springs for intra-maxillary or inter-maxillary traction. Usually, the use of traction hooks is not throughout the entire orthodontic cycle, but only in the early or middle and late stages of orthodontics. However, the traction hooks set on the buccal tubes on the market are all fixed traction hooks, and the current buccal tubes cannot remove the traction hooks when the traction hooks are not in use. Due to its functional requirements, the traction hook stimulates the oral mucosa and easily gives patients a strong foreign body sensation. In addition, the traction hooks on the market all contain sharp angle structures, which cause discomfort to patients. In order to reduce the foreign body sensation of patients, providing a buccal tube that can be stored when the traction hook is not in use can greatly reduce the discomfort caused to patients during the use of the buccal tube.

[0003] Our company's previous patent application CN110584810A discloses a buccal tube with a hidden traction hook, in which a housing space is provided in the body of the buccal tube, and a movable or rotatable traction hook is placed in the housing space in the body when not in use, and is moved or rotated out of the housing space when in use. However, the scheme of this application has three problems: first, because the buccal tube is used to be pasted on the molar, its size is very small, the size of the main body is only 3-6mm, the length of the traction hook is usually about 1-3mm, and a containing space is set inside the main body, and the movable or rotatable traction hook needs to be assembled in the containing space. Because of the small size, in the actual production and processing process, the processing procedures are complicated and difficult, and because of the difficulty in processing, the precision of the product is not ideal, the yield rate of the product is low, and it is difficult to maintain stability after the traction hook is repeatedly moved or rotated; second, because the traction hook is set in the containing space inside the main body, and the size of the traction hook is very small, and the buccal tube is adhered to the patient's molar and located deep in the oral cavity, the doctor cannot observe the position of the traction hook on the buccal tube with the naked eye during the actual operation. It is difficult to align the tool with the traction hook when removing the traction hook from the internal containing space. If the operation is wrong, the tool is very easy to scratch the patient's oral cavity; third, because the processing procedures are complicated and difficult, the processing cost is high and the market promotion and application are very difficult. In order to meet the needs of practical applications, it is necessary to improve the technical solution in the above application and design a buccal tube that can avoid the traction hook from irritating the patient's oral mucosa when not in use, has low actual production and processing difficulty, is easy for doctors to operate, and has a production cost that is acceptable to the market environment. Summary of the invention

[0004] In view of the above technical problems, the present invention provides a buccal tube with a movable traction member.

[0005] The technical solution adopted by the present invention to solve the technical problem is:

[0006] A buccal tube includes a main body, the main body is provided with a movable accessory, the accessory includes a traction part, when the accessory is in use, the traction part moves to a use position; when the accessory is not in use, the accessory moves to the outside of the main body. The traction part moves to the use position in various ways that can be thought of by those skilled in the art, such as movement, rotation or a combination thereof, and the use position of the traction part can be a position protruding relative to the main body, or a position forming a gap or separation with the main body. When the accessory is not in use, the accessory moves to the outside of the main body, and can be close to the outer surface of the main body, or can be outside the outer surface of the main body. When the accessory is not in use, the traction part does not protrude relative to the main body or does not form a gap or separation with the main body, and cannot be used as a traction member. The accessory can be arranged on the outer surface of the main body, or on the bottom plate of the buccal tube, and the bottom plate is a component connected to the main body for sticking on the patient's teeth.

[0007] Compared with the buccal tube described in CN110584810A, the buccal tube of the present application has its own advantages and disadvantages. The buccal tube in CN110584810A is a tube in which the traction hook is arranged in the accommodation space inside the main body, that is, when the traction hook is not in use, the general shape of the traction hook cannot be observed from the outside of the main body, while the attachment in the present application is arranged on the outside of the main body, that is, the general shape of the attachment is observed from the outside of the main body. First, the attachment is arranged outside the main body, such as on the outer surface of the main body, or on the bottom plate, that is, the processing area is changed from the inside of the main body to the outside of the main body, so that the processing is simpler, the operation is easier, and the product precision is higher. Because the process is simpler, the quality of the produced product is easier to control, the product yield is higher, and the quality of the product can be guaranteed; secondly, because the attachment is arranged on the outside of the main body, the doctor can easily position the tool at the position of the attachment and perform operations such as hooking and pulling on it, and it is easier to change it from a non-use state to a use state; thirdly, because the processing process is simplified, the processing cost of the product is reduced, which can be more conducive to market promotion. On the other hand, the buccal tube in CN110584810A hides the traction hook, so it is not easy for the patient to have food residues when eating. However, the buccal tube in the present application has the traction hook arranged on the outside of the main body, which is easy to have food residues, and is not conducive to the patient to clean the teeth.

[0008] In some preferred embodiments, the buccal tube includes a first limiter, which is provided on at least one of the main body and the accessory. When the traction part moves to the use position, the first limiter is used to limit the accessory from continuing to move. In order to prevent the accessory from continuing to move after it moves to the use state, a first limiter is provided on the main body or the accessory to limit the accessory. As long as the accessory can be limited to the use state, the first limiter can be of any shape and position, and the specific position of the first limiter can be determined according to the shape and position of the actual accessory.

[0009] In some preferred embodiments, the buccal tube includes a second stopper, which is provided on at least one of the main body and the accessory, and is used to block the movement of the accessory and restrict it to a non-use state. In order to keep the accessory in a non-use state and prevent the accessory from moving autonomously when it is not expected to be used, a second stopper is provided on the main body or the accessory. When the accessory needs to be used, force is applied to the accessory, and the second stopper is squeezed and deformed, so that the accessory can move, and then the accessory is transformed into a use state.

[0010] In a further preferred embodiment, a limiting protrusion or a limiting recess matching the second limiting member is provided on the main body or the accessory, and when the accessory is not in use, a force is applied to the accessory, and the limiting protrusion or the limiting recess passes over the second limiting member, and then the accessory moves. When the second limiting member is provided on the main body, a limiting protrusion or a limiting recess matching the second limiting member can be provided on the accessory, and when the second limiting member is provided on the accessory, a limiting protrusion or a limiting recess matching the second limiting member can be provided on the main body, and when a force is applied to the accessory, the limiting protrusion or the limiting recess squeezes the second limiting member, and then the limiting protrusion passes over the second limiting member.

[0011] In some preferred embodiments, the outer side of the main body is concave to form a notch, and when the accessory is not in use, the accessory is located at the notch. Because the larger the volume of the buccal tube, the stronger the foreign body sensation in the patient's mouth, and the smaller the volume, the smaller the foreign body sensation in the patient's mouth. The outer side of the main body is concave to form a notch, and when the accessory is not in use, the accessory is located at the notch. Such a design can reduce the overall volume of the buccal tube without affecting the function of the buccal tube. There is no limitation on the specific shape of the notch. In a further preferred embodiment, the shape of the notch can match the shape of the accessory. Patent application CN110584810A discloses a buccal tube in which a traction hook can be hidden, in which a housing space is formed inside the main body, and the housing space has an opening on the outside of the main body, which can be considered as a depression on the outside of the main body, but the depression is not a notch, and at least a part of the traction hook is hidden inside the main body, that is, at least a part of the traction hook is wrapped by the main body, and the general shape of the traction hook cannot be observed from the outside of the main body, especially the part connected to the main body cannot be observed from the outside of the main body, but the present application forms a notch on the outside of the main body, and the traction hook is arranged at the notch, and the general shape of the traction hook can be observed from the outside of the main body. It is a preferred embodiment to form a notch on the outside of the main body by concavely forming a notch, and if no notch is formed on the outside of the main body, it is still within the protection scope of the present application and can also meet the requirements.

[0012] In some preferred embodiments, a moving track accessory is provided on the outer side of the main body, and the accessory can move along the moving track formed by the moving track accessory. The moving track accessory is used to limit the moving direction of the accessory, and the accessory moves along the moving track formed by the moving track accessory to realize the conversion between the non-use state and the use state.

[0013] In some further preferred embodiments, the moving track accessory is a groove or a collar, and the accessory is arranged in the groove or the collar. The moving track can also be any other structure that can limit the moving direction of the accessory.

[0014] In some other preferred embodiments, a shaft is disposed on the outside of the main body, and the accessory is rotatably connected to the main body via the shaft. Because the shaft is disposed on the outside of the main body, there are many optional implementation methods, and production and processing are easier.

[0015] In a further preferred embodiment, the shaft is snap-connected to the main body. The shaft and the main body are snap-connected, which can be a detachable connection or a snap that can only be connected and cannot be removed, such as an interference fit. The shaft and the main body are snap-connected, which makes the assembly of the traction hook easier and the production process of the buccal tube simpler.

[0016] In some further preferred embodiments, the main body is provided with a hole for inserting the shaft, and the end of the shaft connected to the main body is provided with at least two clips, and the two clips can be inserted into the hole when forced together.

[0017] In some further preferred embodiments, the shaft is provided with a fixing protrusion, the inner wall of the hole is provided with a locking protrusion, the shaft is inserted into the hole, and the locking protrusion blocks the fixing protrusion from moving outward. The fixing protrusion and the locking protrusion may both be rigid protrusions, or one or both of them may be elastic protrusions.

[0018] In some preferred embodiments, when the accessory is not in use, the outer surface of the accessory matches the outer surface of the main body to form a smooth surface. The outer surface of the accessory matches the outer surface of the main body to form a smooth surface, which can further reduce the stimulation of the buccal tube to the patient's oral mucosa, and when the patient chews or brushes his teeth, the stress of the buccal tube caused by foreign objects can be evenly dispersed, which can effectively prevent the buccal tube from falling off the bonded teeth due to the force of foreign objects, thereby avoiding medical accidents and repeated bonding. The smooth surface includes a spherical shape, an ellipsoidal shape, etc.

[0019] In some preferred embodiments, the outer surface of the attachment is smooth. The smooth outer surface of the attachment can reduce the irritation of the attachment to the oral cavity during use and prevent the attachment from scratching the oral mucosa of the patient.

[0020] Compared with the prior art, the present invention has the following positive effects: the present invention provides a buccal tube with a movable traction piece, comprising a main body, wherein the main body is provided with a movable accessory, wherein the accessory includes a traction part, wherein when the accessory is in use, the traction part moves to a use position; when the accessory is not in use, the accessory moves to the outside of the main body; when the accessory is in use, the accessory moves to form a traction piece that can be pulled; the present invention changes the fixed traction hook provided on the traditional buccal tube into a movable traction hook, firstly, the accessory is provided on the outside of the main body, which is simpler to process than providing the traction hook in the accommodating space in the main body, because the process is simpler, the quality of the produced products is easier to control, the product yield is higher, so that the quality of the product can be guaranteed; secondly, because the accessory is provided on the outside of the main body, the doctor can easily position the tool at the position of the accessory and perform operations such as hooking and pulling it, and it is easier to change it from a non-use state to a use state; thirdly, because the processing process is simplified, the processing cost of the product is reduced, which can be more conducive to market promotion.

[0033] Embodiment 1:

[0034] Reference Figure 1 , Figure 1: is a front view of the accessory of the buccal tube in the non-use state in Example 1. This embodiment provides a buccal tube, including a main body 100, the main body 100 is provided with a movable accessory 200, the accessory 200 can move relative to the main body 100, the accessory 200 includes a traction part, the traction part is the functional part of the accessory 200, in this embodiment, it is the middle section of the accessory 200, when the accessory is in use, the traction part moves to the use position, the use position of the traction part can be a position protruding relative to the main body 100, or a position where a gap is formed between the main body 100 or separated from the main body 100, as long as a traction tool such as a spring or a rubber band can be hung on the traction part; when the accessory is not in use, the accessory 200 moves to the outside of the main body 100, can be close to the outer surface of the main body 100, or can be outside the outer surface of the main body 100. When the accessory is not in use, the traction part does not protrude relative to the main body 100 or does not form a gap or separation with the main body 100, and cannot be used as a traction member. The accessory 200 may be arranged on the outer surface of the main body, or on the bottom plate of the buccal tube. The bottom plate is a component connected to the main body for pasting on the patient's teeth. In the present embodiment, the accessory 200 is arranged on the outer surface of the main body 100. The accessory 200 is used as a traction hook. Firstly, compared with arranging the traction hook in the accommodating space inside the main body 100, arranging the accessory 200 on the outside of the main body 100 makes the processing simpler, the operation easier, and the product precision higher because the processing position is transferred from the inside of the main body 100 to the outside. Because the process is simpler, the quality of the products produced is easier to control, the product yield is higher, and the quality of the product can be guaranteed; secondly, the buccal tube is used to be bonded to the patient's molar tooth surface. Molars are commonly known as large teeth and are located at the innermost side of the oral cavity. When the buccal tube is bonded to the molar When the doctor is inserting the buccal tube, it is difficult for the doctor to observe the whole picture of the buccal tube, and the doctor can only use tools such as probes to try to find the position of the attachment. When the positioning is wrong, the tool can easily scratch the patient's mouth. In this application, the attachment 200 is set to the outside of the main body 100. When the doctor wants to move the attachment 200, it is easier to position the tool at the position of the attachment 200 and perform operations such as hooking, pulling, and clamping it. It is also easier to change it from a non-use state to a use state, avoiding scratching the patient's mouth due to difficult positioning; thirdly, because the processing technology is simplified, the processing cost of the product is reduced, which can be more conducive to market promotion.

[0035] In order to prevent the accessory 200 from continuing to move after it moves to the use state, a first limiter 300 is provided on the main body 100 or the accessory 200 to limit the accessory 200. As long as the accessory 200 can be limited to the use state, the first limiter 300 can be of any shape and position, and the specific position of the first limiter 300 can be determined according to the shape and position of the actual accessory. The buccal tube includes a first limiter 300, and the first limiter 300 is provided on at least one of the main body 100 and the accessory 200. In this embodiment, the first limiter 300 is provided on the main body 100, and the first limiter 300 is a ring sleeved on the outside of the accessory 200. When the accessory 200 moves to the use state, the first limiter 300 is used to limit the accessory 200 from continuing to move.

[0036] Reference Figure 2-5 , Figure 2 is a right side view of the buccal tube attachment in the non-use state in Example 1, Figure 3 yes Figure 2 Middle AA cross section, Figure 4 This is a right side view of the buccal tube attachment in the first embodiment when it is in use. Figure 5 yes Figure 4 In the BB cross-sectional view in FIG. 1 , in order to keep the accessory 200 in a non-use state and prevent the accessory 200 from automatically moving when it is not expected to be used, the second stopper 400 is provided on at least one of the main body 100 and the accessory 200, and the second stopper 400 is used to block the movement of the accessory 200 and limit it to a non-use state. In this embodiment, the second stopper 400 is provided on the main body 100. When the accessory 200 needs to be used, force is applied to the accessory 200, and the accessory 200 presses the second stopper 400 and then passes over the second stopper 400, so that the accessory 200 can move, and then the accessory 200 is transformed into a use state.

[0037] Reference Figure 3 The accessory 200 is provided with a limiting protrusion 210 matching the second limiting member 400. When the accessory is not in use, force is applied to the accessory 200, the limiting protrusion 210 passes over the second limiting member 400, and then the accessory 200 moves.

[0038] The outer side of the main body 100 is provided with a moving track accessory, and the accessory 200 can move along the moving track formed by the moving track accessory. The moving track accessory is used to limit the moving direction of the accessory 200, and the accessory moves along the moving track to realize the conversion between the non-use state and the use state. In this embodiment, the moving track accessory is a groove 110, and the accessory 200 is arranged in the groove 110. The moving track accessory can also be any other structure that can limit the moving direction of the accessory, such as a ring mounted on the outside of the accessory, and the accessory can move up and down in the ring.

[0039] The outer surface of the attachment 200 is smooth. The smooth outer surface of the attachment 200 can reduce the stimulation of the attachment 200 to the oral cavity when in use, and prevent the attachment 200 from scratching the oral mucosa of the patient.

[0040] One end of the accessory 200 includes a protruding structure. When the accessory is in use, when a traction tool such as a spring or a rubber band is hung on the accessory 200, the protruding structure can prevent the traction tool from falling off the accessory 200. When the traction tool is mounted on the accessory, the traction force can pull the accessory 200 to prevent it from moving back to the non-use state. In a further preferred embodiment, in order to allow the accessory 200 to remain in the use state without moving when the traction tool is not mounted, a third limiting member can be further provided. In the embodiment, the third limiting member is a blocking protrusion 220 provided on the accessory 200 and matching with the second limiting member 400. When the accessory 200 moves from the non-use state to the use state, the limiting protrusion 210 first passes over the second limiting member 400, and then the blocking protrusion 220 passes over the second limiting member 400. The blocking protrusion 220 can prevent the accessory 200 from automatically moving back to the non-use state after reaching the use state.

[0041] Embodiment 2:

[0042] Reference Figure 6-7 , Figure 6 is a front view of the attachment of the buccal tube in Example 2 when not in use, Figure 7This is a front view of the buccal tube in the second embodiment when the attachment is in use. This embodiment provides a buccal tube, including a main body 101, an attachment 201 is arranged on the outside of the main body 101, and the attachment 201 can rotate relative to the main body 101. When the attachment is not in use, the attachment 201 is stored on the outside of the main body 101; when the attachment is in use, the attachment 201 rotates to form a traction member that can be pulled. The attachment 201 is used as a traction hook. First, the attachment 201 is arranged on the outside of the main body 101. In this embodiment, the attachment 201 is arranged on the outer surface of the main body 101. Compared with the traction hook being arranged in the accommodation space inside the main body 101, because the processing position is transferred from the inside of the main body 101 to the outside, the processing is simpler, the operation is easier, and the product precision is higher. Because the process is simpler, the quality of the produced product is easier to control, the product yield rate is higher, and the product quality can be guaranteed; secondly, the buccal tube is used to be bonded to the patient's molar tooth surface. Molars are commonly known as large teeth located in the oral cavity. The innermost side of the buccal tube, when the buccal tube is bonded to the molar, it is difficult for the doctor to observe the whole picture of the buccal tube, and the doctor can only use tools such as probes to try to find the position of the attachment. When the positioning is wrong, the tool can easily scratch the patient's mouth. In this application, the attachment 201 is set to the outside of the main body 101. When the doctor wants to rotate the attachment 201, it is easier to position the tool at the position of the attachment 201 and perform operations such as hooking, pulling, and clamping it. It is also easier to change it from a non-use state to a use state, avoiding scratching the patient's mouth due to difficult positioning; thirdly, because the processing technology is simplified, the processing cost of the product is reduced, which can be more conducive to market promotion.

[0043] The buccal tube includes a first stopper 301, which is disposed on the main body 101 and is a blocking wall. When the accessory 201 rotates to a use state, the first stopper 301 is used to limit the accessory 201 from continuing to rotate.

[0044] In order to keep the accessory 201 in a non-use state and prevent the accessory 201 from automatically rotating when it is not expected to be used, the accessory 201 is provided with a second stopper 401, which is used to block the rotation of the accessory 201 and limit it to a non-use state. The main body 101 is provided with a stopper recess 111 that matches the second stopper 401. When the accessory 201 needs to be used, force is applied to the accessory 201, and the second stopper 401 of the accessory 201 passes over the stopper recess 111, so that the accessory 201 can rotate, and then the accessory 201 is transformed into a use state.

[0045] Reference Figure 8 , Figure 8It is a structural exploded view of the buccal tube in Example 2. A shaft 501 is provided on the outside of the main body 101, and the accessory 201 is rotatably connected to the main body 101 through the shaft 501. Because the shaft 501 is provided on the outside of the main body 101, there are many optional implementation methods, and it is easier to produce and process. In this embodiment, the shaft 501 is connected to the main body 101 by snapping. The shaft 501 and the main body 101 are connected by snapping, which can be a detachable connection or a snapping that can only be connected and cannot be removed, such as interference fit. The main body 101 is provided with a hole 121 for inserting the shaft 501, and one end of the shaft 501 connected to the main body 101 includes two clips 511, and the two clips 511 can be inserted into the hole 121 when they are forced to move close. A protrusion 521 is provided at one end of one of the clips 511 inserted into the hole 121 to prevent the clip 511 from slipping out after being inserted into the hole 121.

[0046] The outer side of the main body 101 is concave to form a notch 131, and when the accessory is not in use, the accessory 201 is located at the notch 131. Because the larger the volume of the buccal tube, the stronger the foreign body sensation in the patient's mouth, and the smaller the volume, the smaller the foreign body sensation in the patient's mouth. The outer side of the main body 101 is concave to form a notch 131, and when the accessory is not in use, the accessory 201 is located at the notch 131. Such a design can reduce the overall volume of the buccal tube without affecting the function of the buccal tube. There is no limitation on the specific shape of the notch 131, and the shape of the notch 131 can match the shape of the accessory 201. Patent application CN110584810A discloses a buccal tube in which a traction hook can be hidden, in which an accommodation space is formed inside the main body, and the accommodation space has an opening on the outside of the main body. It can be considered that a depression is provided on the outside of the main body, but the depression is not a notch. The traction hook is hidden inside the main body, and the general shape of the traction hook cannot be observed from the outside of the main body. However, in the present application, a notch 131 is formed on the outside of the main body 101, and the traction hook is provided in the notch 131. The general shape of the traction hook can be observed from the outside of the main body 101.

[0047] Embodiment 3:

This embodiment provides a buccal tube, including a main body 102, and an accessory 202 is provided on the outer side of the main body 102. The accessory 202 can rotate relative to the main body 102. When the accessory is not in use, the accessory 202 is stored on the outer side of the main body 102; when the accessory is in use, the accessory 202 rotates to form a traction member that can be pulled.

[0049] The buccal tube includes a first stopper 302, which is disposed on the main body 102 and is a blocking wall. When the accessory 202 rotates to the use state, the first stopper 302 is used to limit the accessory 202 from continuing to rotate.

[0050] In order to keep the accessory 202 in a non-use state and prevent the accessory 202 from automatically rotating when it is not expected to be used, the accessory 202 is provided with a second stopper 402, which is used to block the rotation of the accessory 202 and limit it to a non-use state. The main body 102 is provided with a stopper recess 112 that matches the second stopper 402. When the accessory 202 needs to be used, a force is applied to the accessory 202, and the second stopper 402 of the accessory 202 passes over the stopper recess 112, so that the accessory 202 can rotate, and then the accessory 202 is transformed into a use state.

[0051] A notch 132 is formed on the outside of the main body 102, and the accessory 202 is stored in the notch 132 when the accessory is not in use. When the accessory is not in use, the outer surface of the accessory 202 matches the outer surface of the main body 102 to form a smooth surface. The outer surface of the accessory 202 matches the outer surface of the main body 102 to form a smooth surface, which can further reduce the stimulation of the buccal tube to the patient's oral mucosa. Moreover, when the patient chews or brushes his teeth, the stress of the buccal tube caused by foreign objects can be evenly dispersed, which can effectively prevent the buccal tube from falling off the bonded teeth due to the force of foreign objects, thereby avoiding medical accidents and repeated bonding. The smooth surface includes a rounded rectangular parallelepiped, a spherical shape, an ellipsoidal shape, etc. In this embodiment, the outer surface of the accessory 202 matches the outer surface of the main body 102 to form a rounded rectangular parallelepiped.
