Description

Technical Field

[0001] This utility model relates to medical devices, and in particular to an optical navigation system. Background Technology

[0002] To facilitate precise dental surgery, an optical navigation system is typically installed on a dental handpiece. Existing optical navigation systems use a single, integral plastic frame as the mounting medium for the LED chips. This existing plastic frame is a single sheet material, with the wiring exposed beneath it, resulting in poor aesthetics, increased susceptibility to wire damage, and an inability to sterilize the wiring. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an optical navigation system.

[0004] The technical solution adopted by this utility model to solve its technical problem is: an optical navigation system, including a connecting component, a base disposed on the connecting component, and a skeleton disposed on the base. The skeletons are interconnected and are hollow tubular. Lamp bead holes are distributed on the skeleton, and lamp bead assemblies are installed in the lamp bead holes. The lamp bead assembly includes a lamp holder disposed in the lamp bead hole, an LED lamp bead disposed on the top surface of the lamp holder, and a wire disposed in the skeleton. One end of the wire is connected to the LED lamp bead, and the other end of the wire passes through the base. The connecting component is fitted onto a dental handpiece, and the skeleton is a 3D metal printed structure.

[0005] As a further improvement to this design, the lamp holder is made of PEEK material. The lamp holder includes a connecting part that extends into the lamp bead hole and a step that mates with the opening end face of the lamp bead hole. The outer diameter of the step is larger than the opening diameter of the lamp bead hole. A glue-receiving groove is provided at the connection between the connecting part and the step, and the glue-receiving groove is filled with sealant.

[0006] As a further improvement to this design, the connecting assembly includes a connector fixed to the dental handpiece, a locking sleeve threaded to the connector, and a connecting sleeve fitted onto the dental handpiece. The connector has a passive toothed ring at its end and an active toothed ring at its head. Both the active and passive toothed rings have teeth on their end faces. The active and passive toothed rings mesh with each other. The locking sleeve abuts against the active toothed ring and applies pressure toward the passive toothed ring to the active toothed ring.

[0007] As a further improvement to this design, an elastic element is sandwiched between the locking sleeve and the driving gear ring, and the elastic element applies a spring force toward the driven gear ring.

[0008] As a further improvement to this design, the base is detachably connected to a bottom plate, the bottom end of the bottom plate is provided with a hook claw, the front end of the base is provided with a connecting hole, the connecting sleeve is provided with a hooking hole that cooperates with the hook claw, and the connecting sleeve is provided with a screw hole that connects with the screw in the connecting hole.

[0009] The beneficial effects of this utility model are: the hollow skeleton structure facilitates the protection of the filament, and the 3D printed metal structure facilitates personalized customization, is suitable for high-temperature disinfection environments, and facilitates subsequent disinfection operations.

[0015] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments. The illustrative embodiments and descriptions are only used to explain the present invention and are not intended to limit the present invention.

[0016] Example: An optical navigation system includes a connecting component 1, a base 2 disposed on the connecting component 1, and a skeleton 3 disposed on the base 2. The skeletons 3 are interconnected and are hollow tubular. Lamp bead holes 30 are distributed on the skeleton 3. Lamp bead assemblies 4 are installed in the lamp bead holes 30. The lamp bead assembly 4 includes a lamp holder 40 disposed in the lamp bead hole 30, an LED bead 41 disposed on the top surface of the lamp holder 40, and a wire (not shown in the figure) disposed in the skeleton 3. One end of the wire is connected to the LED bead 41, and the other end of the wire passes through the base 2. The connecting component 1 is fitted onto a dental handpiece 16, and the skeleton 3 is a 3D metal printed structure.

[0017] The hollow skeleton structure described above facilitates the protection of the filaments, while the 3D printed metal structure allows for personalized customization, is suitable for high-temperature sterilization environments, and facilitates subsequent sterilization operations.

[0018] To improve the stability of the lamp holder 40 at high temperatures, the lamp holder 40 is made of PEEK material. To facilitate the installation of the lamp bead assembly 4, the lamp holder 40 includes a connecting portion 402 extending into the lamp bead hole 30 and a step 400 that mates with the opening end face of the lamp bead hole 30. The outer diameter of the step 400 is larger than the opening diameter of the lamp bead hole 30. To prevent liquid seepage, a sealant-containing groove 401 is provided at the connection between the connecting portion 402 and the step 400, and the sealant-containing groove 401 is filled with sealant. The sealant-containing groove 401 prevents voids in the sealant, ensuring its sealing performance.

[0019] To facilitate adjustment of the rotation angle of the frame 3, the connecting assembly 1 includes a connecting seat 12 fixed to the dental handpiece 16, a locking sleeve 10 threadedly engaged with the connecting seat 12, and a connecting sleeve 11 fitted onto the dental handpiece 16. The connecting seat 12 has a passive gear ring 14 at its end, and the connecting sleeve 11 has an active gear ring 13 at its head. Both the active gear ring 13 and the passive gear ring 14 have teeth on their mating end faces, and they mesh with each other. The locking sleeve 10 abuts against the active gear ring 13 and applies pressure towards the passive gear ring 14 to the active gear ring 13, locking the connecting sleeve 11 after tightening.

[0020] In order to increase the rotational damping between the active gear ring 13 and the passive gear ring 14 and prevent accidental rotation during adjustment, an elastic element 15 is sandwiched between the locking sleeve 10 and the active gear ring 13. The elastic element 15 applies a spring force to the active gear ring 13 toward the passive gear ring 14.

[0021] To facilitate the quick disassembly of the frame 3 and the frequent disinfection of the dental handpiece 16, a base plate 5 is detachably connected to the bottom of the base 2. The bottom end of the base plate 5 is provided with a hook 6, and the front end of the base 2 is provided with a connecting hole 8. The connecting sleeve 11 is provided with a hooking hole 7 that mates with the hook 6, and the connecting sleeve 11 is provided with a screw hole that connects to the screw 9 inside the connecting hole 8.

[0022] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
