Description

Technical Field

[0001] This invention relates to a surgical instrument, and more particularly to an impacted tooth traction device for use in oral treatment. Background Technology

[0002] Impacted teeth are teeth that are completely embedded in the jawbone and cannot erupt normally to the occlusal plane of the oral cavity. They are a common condition in orthodontic clinics. The main causes include abnormal tooth germ development, dentigerous cyst formation, premature loss of deciduous teeth leading to forward displacement of permanent teeth, abnormal root morphology (such as curvature), and tissue adhesions following trauma. Impacted teeth can disrupt the integrity of the dentition, causing adjacent teeth to tilt into the gap, leading to malocclusion. Long-term pressure on adjacent teeth can induce root resorption, accompanied by decreased chewing efficiency, and can also adversely affect speech function and facial aesthetics. Therefore, traction correction of impacted teeth is a significant challenge in orthodontic clinics.

[0003] During the traction orthodontic treatment of impacted teeth, the spatial orientation of the crown and root adjusts dynamically in real time according to the direction of the traction force as the teeth move. This biological characteristic requires that the direction of the traction force at the free end of the traction device be adjusted in real time according to the progress of traction during clinical operation. In addition, as the distance between the crown of the traction tooth and the occlusal surface gradually shortens, it is necessary not only to dynamically adjust the length of the free end traction component, but also, in the later stages of traction, to maintain the constant traction force value required clinically, it is often necessary to place the anchorage device in the opposing dentition to extend the traction arm. This transmaxillary traction operation requires the patient's cooperation in the independent insertion and removal of the orthodontic elastic band. The realization of this operation requires that both the anchorage archwire and the free end of the traction device have an open hook structure to meet the needs of convenient attachment of the orthodontic elastic band.

[0004] Currently, commonly used traction devices for impacted teeth in clinical practice are mainly divided into two categories: The first type of device has a rigid connection between the free end and the fixed end bonded to the tooth surface. The direction of the free end cannot be adjusted, and the length of the free end cannot be adjusted during traction. As the impacted tooth moves under traction, the free end is prone to occlusal interference, affecting the orthodontic process. The second type of device has a movable connection between the fixed end and the free end. The free end can be freely adjusted in multiple directions and its length can be dynamically adjusted according to the traction distance. However, because its free end lacks an open hook structure, it cannot be fitted with a closed orthodontic rubber band, making it difficult to meet traction requirements.

[0005] In summary, current orthodontic treatment for impacted teeth, especially in the later stages of cross-occlusal traction where patients need to independently attach and remove orthodontic elastics, often faces technical bottlenecks, such as the inability to conveniently attach the elastics or the difficulty in simultaneously achieving precise control over the length and direction of the free end. Therefore, developing an auxiliary traction device for impacted teeth that combines flexible and adjustable traction direction, real-time controllable free end length, and allows patients to independently attach orthodontic elastics has significant clinical application value. Summary of the Invention

[0006] The purpose of this invention is to solve the technical bottlenecks that are common in the treatment of impacted teeth, especially in the later stages of cross-occlusal traction when patients need to independently remove and put on orthodontic rubber bands. These bottlenecks include the inability to conveniently attach orthodontic rubber bands or the difficulty in simultaneously achieving precise control of the length and direction of the free end. By setting up an integrated traction mechanism, which integrates the functions of the connecting ring and the traction hook, an adjustable chain structure can be constructed to achieve precise control of the length and direction of the free end. The traction device can also be conveniently installed and removed through the traction part.

[0007] The integrated adjustable impacted tooth traction device of the present invention is characterized in that: the integrated adjustable impacted tooth traction device 100 includes a base 1 and an integrated adjustable traction mechanism 2; A. The base 1 includes a tooth fixing part 11 and a connecting part 12; B. The integrated adjustable traction mechanism 2 is located at the proximal end of the connecting part 12. The integrated adjustable traction mechanism 2 includes an adjustable traction chain 21. The adjustable traction chain 21 is provided with at least two integrated traction mechanisms 21-1. The integrated traction mechanism 21-1 includes a connecting ring 21-11 and a traction part 21-12. The connecting ring 21-11 can be connected to form the adjustable traction chain 21. The traction part 21-12 is provided with an opening 21-12-1. The traction device can enter the traction part 21-12 through the opening 21-12-1 to perform continuous traction on the impacted tooth.

[0008] The adjustable traction chain 21 is typically formed by interconnecting multiple integrated traction mechanisms 21-1 in a chain-like structure. During traction, it constitutes the free end of the integrated adjustable impacted tooth auxiliary traction device 100, enabling precise control of length and direction. The tooth fixing part 11 constitutes the rigid fixing part of the integrated adjustable impacted tooth auxiliary traction device 100, and is typically rigidly fixed to the surface of the impacted tooth that needs traction by bonding, thereby applying traction force to the impacted tooth.

[0009] The bottom 21-12-3 of the traction part 21-12 is located on the side away from the tooth fixation part 11 and has a smooth outer surface. The opening direction of the opening 21-12-1 faces the tooth fixation part 11. During traction, the traction device, usually a closed orthodontic rubber band, is inserted along the opening 21-12-1 and slides towards the bottom 21-12-3 of the traction part 21-12, and is stably attached to the bottom 21-12-3. This reverse opening design ensures that the closed orthodontic rubber band can be stably attached to the bottom 21-12-3 without falling off during the traction process of the integrated adjustable impacted tooth auxiliary traction device 100 due to the outward traction effect. Moreover, since the bottom 21-12-2 has a smooth outer surface, as the adjustable traction chain 21 is gradually pulled out of the tissue, it will not cause damage to the gingival tissue during the traction process, making it very safe for clinical use.

[0010] The integrated adjustable impacted tooth traction device of the present invention, through the integrated traction mechanism 21-1, can not only construct an adjustable chain structure through the interconnection of the connecting rings 21-11 to achieve precise control of the length and direction of the free end, but also construct an open hook structure of the free end through the integrated design of the opening 21-12-1, so that the closed orthodontic rubber band can be directly attached for traction. It can be adapted to patients to complete the orthodontic rubber band attachment operation independently, which is very convenient and quick for clinical application.

[0011] The connecting ring 21-11 and the traction part 21-12 are integrally manufactured components, and the traction part 21-12 is a traction hook 21-12-2. The connecting ring 21-11 and the traction part 21-12 can be integrally stamped and then welded together to form a chain, constituting the adjustable traction chain 21. This stamping manufacturing method allows for the design of connecting rings 21-11 and traction parts 21-12 in different shapes as needed.

[0012] The connecting ring 21-11 also constitutes the traction part 21-12. The connecting ring 21-11 has an open structure, with the opening forming the opening 21-12-1. The opening 21-12-1 can be opened and closed by making the size of the opening 21-12-1 smaller than the size of the connecting ring 21-11, or by using a switch 21-12-4. This allows the connecting ring 21-11 to form a stable chain connection while also allowing orthodontic elastic bands to be attached through the opening 21-12-1, resulting in a very simple structure.

[0013] The integrated traction mechanism 21-1 is a double-coil spring 2101, with the inner coil forming the connecting ring 21-11 and the outer coil forming the traction part 21-12. This double-coil spring structure can maintain a sealed chain connection and, through the tight fit of the inner and outer coils, maintain a very small chain-like external size, resulting in a smaller incision during clinical use.

[0014] The adjustable traction chain 21 is formed by interconnecting the connecting rings 21-11. The direct interconnection of the connecting rings 21-11 forms the adjustable traction chain 21, which can ensure more precise control of size and direction.

[0015] The tooth fixation part 11 has a surface shape that matches the outer contour of the tooth. The surface of the tooth fixation part 11 may also be designed with micropores to increase the bonding area and better ensure that the tooth fixation part 11 is better bonded to the surface of the impacted tooth that needs to be pulled by having a surface shape that matches the outer contour of the tooth.

[0016] The adjustable traction chain 21 is made of medical materials.

[0017] The medical material is medical-grade stainless steel or medical-grade shape memory alloy. The medical material needs to have good rigidity to ensure that it does not deform during the traction process and to guarantee continuous tensile force.

[0018] The integrated adjustable impacted tooth traction device of the present invention includes a base 1 and an integrated adjustable traction mechanism 2. The base 1 is connected to the surface of the impacted tooth that needs traction. The integrated adjustable traction mechanism 2 includes an adjustable traction chain 21, on which at least two integrated traction mechanisms 21-1 are provided. Each integrated traction mechanism 21-1 includes a connecting ring 21-11 and a traction part 21-12. The connecting ring 21-11 can be connected to form the adjustable traction chain 21. The traction part 21-12 has an opening 21-12-1, through which the traction device can enter the traction part 21-12 for continuous traction of the impacted tooth. The integrated adjustable impacted tooth traction device of the present invention, through the integrated traction mechanism 21-1, can not only construct an adjustable chain structure through the interconnection of the connecting rings 21-11 to achieve precise control of the length and direction of the free end, but also construct an open hook structure of the free end through the integrated design of the opening 21-12-1, so that the closed orthodontic rubber band can be directly attached for traction. It can be adapted to patients to complete the orthodontic rubber band attachment operation independently, which is very convenient and quick for clinical application. Attached Figure Description

The surface of the tooth fixing part 11 may also be designed with micropores, networks, etc., to increase the bonding area and better ensure that the tooth fixing part 11 is better bonded to the surface of the impacted tooth that needs to be pulled by having a surface shape that matches the outer contour of the tooth.

[0033] The integrated adjustable traction mechanism 2 is located at the proximal end of the connecting part 12. The integrated adjustable traction mechanism 2 includes an adjustable traction chain 21, on which at least two integrated traction mechanisms 21-1 are provided. Each integrated traction mechanism 21-1 includes a connecting ring 21-11 and a traction part 21-12. The connecting ring 21-11 can be connected to form the adjustable traction chain 21. The traction part 21-12 is provided with an opening 21-12-1, through which a traction device can enter the traction part 21-12 to perform continuous traction on impacted teeth.

[0034] refer to Figure 1 In this embodiment, the adjustable traction chain 21 is formed by interconnecting the connecting rings 21-11. The direct interconnection of the connecting rings 21-11 to form the adjustable traction chain 21 ensures more precise control over size and direction.

[0035] The adjustable traction chain 21 is typically formed by interconnecting multiple integrated traction mechanisms 21-1 in a chain-like structure. During traction, it constitutes the free end of the integrated adjustable impacted tooth auxiliary traction device 100, enabling precise control of length and direction. The tooth fixing part 11 constitutes the rigid fixing part of the integrated adjustable impacted tooth auxiliary traction device 100, and is typically rigidly fixed to the surface of the impacted tooth that needs traction by bonding, thereby applying traction force to the impacted tooth.

[0036] refer to Figure 1 The bottom 21-12-3 of the traction part 21-12 is located on the side away from the tooth fixation part 11 and has a smooth outer surface. The opening direction of the opening 21-12-1 faces the tooth fixation part 11. During traction, the traction device, usually a closed orthodontic rubber band, is inserted along the opening 21-12-1 and slides towards the bottom 21-12-3 of the traction part 21-12, and is stably attached to the bottom 21-12-3. This reverse opening direction design allows the closed orthodontic rubber band to be stably attached to the bottom 21-12-3 without falling off during the traction process of the integrated adjustable impacted tooth auxiliary traction device 100 due to the outward traction effect. Moreover, since the bottom 21-12-2 has a smooth outer surface, as the adjustable traction chain 21 is gradually pulled out of the tissue, it will not cause damage to the gingival tissue during the traction process, making it very safe for clinical use.

[0037] In this embodiment, reference Figure 1The connecting ring 21-11 and the traction part 21-12 are integrally manufactured components, and the traction part 21-12 is a traction hook 21-12-2. The connecting ring 21-11 and the traction part 21-12 can be integrally stamped and then welded together to form a chain, constituting the adjustable traction chain 21. This stamping manufacturing method allows for the design of connecting rings 21-11 and traction parts 21-12 in different shapes as needed.

[0038] The adjustable traction chain 21 is made of medical materials.

[0039] The medical material is medical-grade stainless steel or medical-grade shape memory alloy. The medical material needs to have good rigidity to ensure that it does not deform during the traction process and to guarantee continuous tensile force.

[0040] The integrated adjustable impacted tooth traction device in this embodiment, through the integrated traction mechanism 21-1, can not only construct an adjustable chain structure through the interconnection of the connecting rings 21-11 to achieve precise control of the length and direction of the free end, but also construct an open hook structure of the free end through the integrated design of the opening 21-12-1, so that the closed orthodontic rubber band can be directly attached for traction. It can be adapted to patients to complete the orthodontic rubber band attachment operation independently, which is very convenient and quick for clinical application.

[0041] Example 2: The integrated adjustable impacted tooth traction device of the present invention with a double-coil spring structure

[0042] refer to Figure 2 The difference between this embodiment and embodiment 1 is that in this embodiment, the integrated traction mechanism 21-1 is a double-rotary spring 2101.

[0043] The integrated traction mechanism 21-1 is a double-coil spring 2101, with the inner spring forming the connecting ring 21-11 and the outer spring forming the traction part 21-12. The opening of the outer spring forms the opening 21-12-1, which faces the tooth fixing part 11. During traction, the orthodontic elastic band is inserted along the opening 21-12-1, slides towards the bottom 21-12-3 of the outer spring, and is stably attached to the bottom 21-12-3.

[0044] Compared to Example 1, the double-rotor spring structure used in this example can maintain a sealed chain connection and, through the tight fit of the inner and outer springs, maintain a very small chain-like external size, resulting in a smaller incision during clinical use.

[0045] Example 3: The integrated adjustable impacted tooth traction device of the present invention, which integrates the connecting ring and the traction unit.

[0046] refer to Figures 3 to 3-3 The difference between this embodiment and embodiment 1 is that in this embodiment, the connecting ring 21-11 also constitutes the traction part 21-12.

[0047] refer to Figures 3 to 3-3 In this embodiment, a switch 21-12-4 is provided on the side of the connecting ring 21-11. The connecting rings 21-11 are interconnected to form the adjustable traction chain 21. When the switch 21-12-4 is turned on, the opening forms the opening 21-12-1 (see reference). Figure 3-3 The orthodontic rubber band is inserted and mounted from the switch 21-12-4.

[0048] In practical applications, the connecting ring 21-11 can also be designed as an open structure, with the opening forming the opening 21-12-1. By making the size of the opening 21-12-1 smaller than the size of the connecting ring 21-11, a stable connection between the connecting rings 21-11 can be ensured, while retaining the entrance for the orthodontic rubber band.

[0049] In this embodiment, the connecting ring 21-11 also constitutes the traction part 21-12, so that the connecting ring 21-11 can form a stable chain connection to achieve precise control of the size and direction of the free end, and can also allow the orthodontic rubber band to be mounted through the opening 21-12-1. The structure is very simple.
