Description

Technical Field

[0001] This utility model relates to the field of orthodontic technology, specifically to an anchorage positioning and navigation device. Background Technology

[0002] In orthodontic treatment, the precise implantation of anchorage screws plays a crucial role. It is the key to achieving precise control of tooth movement. By implanting anchorage screws, a stable mechanical anchor point can be provided, avoiding reliance on healthy teeth as anchorage. The characteristic of direct anchoring to the jawbone can resist the reaction force in the orthodontic force system and ensure the precise transmission of orthodontic force.

[0003] When implanting anchorage screws, the surgeon's experience and skills can be limited, making it difficult to ensure the screws are implanted horizontally. This necessitates repeated adjustments, making it difficult for traditional anchorage screws to meet the precision requirements of modern orthodontics. Therefore, there is an urgent need to develop an anchorage positioning and navigation device to solve these practical problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a support-based positioning and navigation device, thus solving the aforementioned problems.

[0005] To achieve the above objectives, this utility model provides a support positioning and navigation device through the following technical solution: a gripping rod, wherein an abutment plate is rotatably mounted on the output end of the gripping rod.

[0006] It also includes a navigation and positioning mechanism, which includes a telescopic arc plate disposed inside the contact plate, with one end of the telescopic arc plate extending out of the contact plate. A rack is fixedly installed on one side of the telescopic arc plate, and a housing is fixedly installed on one side of the contact plate. A motor is fixedly installed inside the housing. A gear plate is fixedly installed at the output end of the motor, and the gear plate meshes with the rack. A positioning seat is fixedly installed at one end of the telescopic arc plate, and a conical guide seat is fixedly installed inside the positioning seat.

[0007] Preferably, a headrest is provided on one side of the grip bar.

[0008] Preferably, it also includes an auxiliary fixing mechanism, which includes a torsion spring seat disposed on one side of the headrest plate, a strap wrapped around the outside of the torsion spring seat, one end of the strap being fixedly connected to one side of the grip rod, a bearing seat rotatably mounted on one end of the torsion spring seat, a turntable fixedly mounted on the outer periphery of the bearing seat, a positioning bolt threaded on one side of the bearing seat, and a rubber band fixedly mounted on one side of the torsion spring seat, one end of the rubber band being fixedly connected to the other side of the grip rod.

[0009] Preferably, a silicone pad is fixedly installed on one side of the headrest plate, and a steel plate is fixedly installed on the inner side of the silicone pad.

[0010] Preferably, a rubber strip is fixedly installed on one side of the contact plate.

[0011] Preferably, a pivot seat is rotatably mounted on one side of the housing, and one end of the pivot seat is fixedly connected to one end of the grip rod.

[0012] This invention provides a supported positioning and navigation device. Compared with the prior art, it has the following advantages:

[0013] Beneficial effects

[0014] 1. The motor drives the toothed disc to rotate. Through the meshing transmission between the toothed disc and the rack, the telescopic arc plate extends smoothly from the contact plate at a set angle, allowing the positioning seat to move to the pre-planned implantation position. The anchorage screw is then inserted, and its tip contacts the conical guide seat. The tapered structure of the conical guide seat guides the anchorage screw to align with the implantation position at a preset angle. At the same time, the rigid support of the positioning seat ensures the stability of the instrument during implantation. The linkage of the motor, toothed disc, and rack enables the navigation of the anchorage screw, while the cooperation between the conical guide seat and the positioning seat ensures the implantation angle and positioning convenience of the anchorage screw. This solves the problem that the level of the anchorage screw cannot be guaranteed when implanting it due to the limitations of the doctor's experience and skills. It also eliminates the need for repeated adjustments to the implanted anchorage screw.

[0015] 2. Utilizing the high elasticity of the rubber band, the device is worn on the user's head. The rubber band automatically adjusts its tightness according to the head circumference. Then, the turntable is rotated clockwise. The turntable drives the torsion spring seat to rotate synchronously through the bearing seat. At this time, the built-in spiral torsion spring generates elastic deformation and stores potential energy. As the torsion spring seat rotates, the strap wrapped around its outer side is gradually rolled up. The other end of the strap transmits tension through the gripping rod, causing the contact plate to move towards the teeth in the oral cavity until the contact plate is tightly attached to the tooth surface. At this time, the positioning bolt is tightened to fix the turntable in the current position. The continuous elasticity of the torsion spring maintains the tension of the strap, thus forming a stable three-point fixation structure. This realizes the function of the auxiliary fixation device and avoids the problem of displacement of the orthopedic screw implantation caused by external impact or user pain movement during use.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] First implementation method:

[0023] refer to Figure 1-4 A supported positioning and navigation device includes a gripping rod 1, with an abutment plate 2 rotatably mounted on the output end of the gripping rod 1;

[0024] It also includes a navigation and positioning mechanism 3, which includes a telescopic arc plate 301 disposed inside the contact plate 2, and one end of the telescopic arc plate 301 extends out of the contact plate 2. A rack 302 is fixedly installed on one side of the telescopic arc plate 301, and a housing is fixedly installed on one side of the contact plate 2. A motor 303 is fixedly installed inside the housing. A gear plate 304 is fixedly installed at the output end of the motor 303, and the gear plate 304 meshes with the rack 302. A positioning seat 305 is fixedly installed at one end of the telescopic arc plate 301, and a conical guide seat 306 is fixedly installed inside the positioning seat 305.

[0025] A headrest plate 6 is provided on one side of the grip rod 1. A silicone pad 8 is fixedly installed on one side of the headrest plate 6, and a steel plate 801 is fixedly installed on the inner side of the silicone pad 8. A rubber strip 4 is fixedly installed on one side of the contact plate 2. A rotating shaft seat 5 is rotatably installed on one side of the housing, and one end of the rotating shaft seat 5 is fixedly connected to one end of the grip rod 1.

[0026] By moving the grip rod 1, the contact plate 2 is brought into contact with the tooth surface. The rubber strip 4 prevents the hard contact plate 2 from directly contacting the user's teeth, improving the user experience of the device. The rotating shaft seat 5 facilitates the rotation of the contact plate 2, thereby making it easy to adjust the position of the positioning seat 305 according to the user's needs.

[0027] When the anchorage screw needs to be implanted, the motor 303 is started to drive the toothed disc 304 to rotate. Through the meshing transmission between the toothed disc 304 and the rack 302, the telescopic arc plate 301 is driven to extend smoothly from the contact plate 2 at a set angle, so that the positioning seat 305 moves to the implantation position planned before the operation.

[0028] The operator manually inserts the anchorage screw along the central axis of the positioning seat 305. The tip of the anchorage screw first contacts the tapered guide seat 306. The tapered guide seat 306 guides the anchorage screw to be aligned with the implantation position at a preset angle. At the same time, the rigid support of the positioning seat 305 ensures the stability of the instrument during the implantation process. The linkage of the motor 303, the gear plate 304, and the rack 302 realizes the navigation function of the anchorage screw. The cooperation between the tapered guide seat 306 and the positioning seat 305 ensures the convenience of the implantation angle and positioning of the anchorage screw, which solves the problem that the horizontal state of the anchorage screw cannot be guaranteed when implanting the anchorage screw due to the limitations of the doctor's experience and skills.

[0029] The toughness of the steel plate 801 facilitates the support of the silicone pad 8, while the soft silicone material of the silicone pad 8 prevents the steel plate 801 from directly contacting the user's head, thus improving the user's wearing experience.

[0030] Second implementation method:

[0031] When using the device, the device may shift due to external impacts or movement caused by pain experienced by the user, resulting in displacement of the anchorage nail implantation.

[0032] refer to Figure 1-3 In the second embodiment of this utility model, an auxiliary fixing mechanism 7 is also included. The auxiliary fixing mechanism 7 includes a torsion spring seat 701 disposed on one side of the headrest plate 6. A strap 702 is wrapped around the outside of the torsion spring seat 701, and one end of the strap 702 is fixedly connected to one side of the grip rod 1. A bearing seat is rotatably mounted on one end of the torsion spring seat 701. A turntable 703 is fixedly mounted on the outer periphery of the bearing seat, and a positioning bolt is threaded on one side of the bearing seat. A rubber band 704 is fixedly mounted on one side of the torsion spring seat 701, and one end of the rubber band 704 is fixedly connected to the other side of the grip rod 1.

[0033] Utilizing the high elasticity of the rubber band 704, the device is worn on the user's head. The rubber band 704 can automatically adjust its tightness according to the head circumference. Then, the turntable 703 is rotated clockwise. The turntable 703 drives the torsion spring seat 701 to rotate synchronously through the bearing seat. At this time, the built-in spiral torsion spring generates elastic deformation and stores potential energy. As the torsion spring seat 701 rotates, the strap 702 wrapped around its outer side is gradually wound up. The other end of the strap 702 transmits tension through the grip rod 1, causing the abutment plate 2 to move towards the teeth in the oral cavity until the abutment plate 2 is tightly attached to the tooth surface. At this time, the positioning bolt is tightened to fix the turntable 703 in the current position. The continuous elasticity of the torsion spring maintains the tension of the strap 702, thereby forming a stable three-point fixation structure. This realizes the function of the auxiliary fixation device and avoids the problem of displacement of the orthopedic screw implantation caused by external impact or user pain movement during use.

[0034] When the device needs to be removed, the turntable 703 is rotated counterclockwise to release the potential energy of the torsion spring. The strap 702 automatically resets under the action of the torsion spring's rebound force, and the contact plate 2 disengages from the tooth surface. The entire adjustment process can be completed without tools and with one hand, making it suitable for users with different head circumferences.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
