Root canal therapy generally includes three main steps: root canal preparation and shaping, root canal irrigation, and root canal filling. Among these, root canal irrigation is a crucial step in infection control during root canal treatment. Root canal irrigation can be performed using laser-induced plasma activation (LIPA) technology, which utilizes the photo-breakdown effect of a laser on the liquid to generate cavitation bubbles, creating an optical focal point and photo-breakdown effect within the liquid.

[0019] It should be noted that, unless otherwise specified, the embodiments and technical features in the embodiments of this application can be combined with each other, and the detailed descriptions in the specific implementation should be understood as explanations of the purpose of this application and should not be regarded as undue limitations on this application.

[0020] In related technologies, a light guide device is used to guide a laser to induce photo-breakdown within the liquid used for cleaning root canals. The light guide device includes a light guide mirror, through which the laser incident on the device is reflected and / or focused. The light exit direction of the light guide device is approximately along the direction of the light guide mirror pointing towards its focal point. The laser, focused by the light guide mirror, induces photo-breakdown within the root canal cleaning liquid, generating cavitation bubbles. However, the laser exit direction within the light guide device is almost fixed relative to the length of the handle; the laser exit direction relative to the length of the handle cannot be adjusted, and the angle between the laser exit direction and the length of the handle cannot be adjusted.

[0021] Therefore, this disclosure provides a light guiding device. Please refer to the embodiments provided. Figures 1-10 The light guiding device includes a handpiece and a light guide mirror. The light guide mirror is used to reflect and / or focus light.

[0022] For example, the light guide mirror includes a reflector for reflecting light.

[0023] For example, light propagating in the handle propagates to the reflector, and the light propagating from the handle to the reflector is the incident light of the reflector. The reflector reflects the light propagating from the handle to the reflector.

[0024] For example, the reflector is a plane reflector, which can reflect light but cannot focus it.

[0025] For example, the reflector is a concave reflector, which can both reflect and focus light.

[0026] For example, the light guide mirror also includes a focusing mirror for focusing light.

[0027] For example, a focusing lens is used to receive and focus the light reflected from the mirror. For example, a light guide is mounted on a handpiece. The operator holds the handpiece to guide the laser into the liquid used to clean the root canal, thereby creating a photo-breakdown effect.

[0028] For example, a reflector and a focusing lens are mounted on the handpiece. The laser incident on the handpiece propagates to the reflector and then to the focusing lens. The light guide device outputs the light through the focusing lens, so that the laser is focused onto the cleaning fluid in the root canal to clean the root canal.

[0029] This disclosure provides a handpiece for guiding light. Please refer to [link / reference]. Figures 1-10 The handpiece includes a handle 1, an adjuster 2, and a frame assembly 5. The length direction of the handle 1 is a first direction R1. The adjuster 2 is disposed on the handle 1. The frame assembly 5 is used to mount a light guide lens for reflecting and / or focusing the light propagated from the handle 1. The frame assembly 5 is mounted on the adjuster 2, which is used to drive at least a portion of the frame assembly 5 to rotate relative to the handle 1. The central axis of rotation of the frame assembly 5 is arranged intersecting the first direction R1.

[0030] The light-emitting direction of the light guide device is roughly along the direction from the light guide mirror to the focal point of the light guide mirror.

[0031] The handpiece used for guiding light does not mean that the handpiece itself can guide light. Rather, the handpiece serves as the main structure for mounting the light guide mirror. The light guide mirror is supported by the handpiece and guided by the light guide mirror mounted on the handpiece.

[0032] It is understandable that the rotation center line of the frame assembly 5 can be the relative rotation between the two structures of the frame assembly 5 itself, or the rotation of the frame assembly 5 relative to an external reference.

[0033] For example, the rotation of the frame assembly 5 relative to the external reference can be such that the frame assembly 5 rotates while the external reference remains stationary.

[0034] For example, the rotation of the frame assembly 5 relative to the external reference can be such that the frame assembly 5 remains stationary while the external reference rotates.

[0035] At least a portion of the frame assembly 5 may rotate relative to the handle 1. This rotation may be either the entire frame assembly 5 rotating relative to the handle 1 or a portion of the frame assembly 5 rotating relative to the handle 1.

[0036] The light-emitting direction of the light guide device is the same as the light-emitting direction of the light guide mirror. The light-emitting direction of the light guide mirror is approximately the direction in which the light guide mirror points to the focal point of the light guide mirror.

[0037] For example, the light-emitting direction of the light guide mirror is arranged to intersect the first direction R1 and the central axis of rotation of the mirror frame assembly 5.

[0038] For example, the central axis of rotation of the frame assembly 5 is perpendicular to the first direction R1 and the light output direction of the light guide mirror, respectively.

[0039] For example, a light guide is mounted on the frame assembly 5. The light guide is used to reflect and / or focus the light propagated from the handle 1. The light output direction of the light guide is arranged to intersect the first direction R1 and the central axis of rotation of the frame assembly 5.

[0040] In this embodiment, at least a portion of the frame assembly 5 is rotated relative to the handle 1 by the adjuster 2. Since the central axis of rotation of the frame assembly 5 intersects with the first direction R1, the angle between the direction of the light guide mirror mounted on the frame assembly 5 pointing to the focal point of the light guide mirror and the first direction R1 changes during the rotation driven by the adjuster 2. The approximate light emission direction of the light guide mirror pointing to the focal point of the light guide mirror is adjustable relative to the first direction R1. This allows the operator to hold the handle 1 at a more suitable angle for cleaning the root canal, making the operation flexible and convenient.

[0041] In some embodiments, please refer to Figures 1-10 The lens frame assembly 5 includes a first lens frame 3 and a second lens frame 4. The first lens frame 3 is used to install the reflector in the light guide mirror and is mounted on the adjuster 2. The second lens frame 4 is used to install the focusing mirror in the light guide mirror and is mounted on the adjuster 2. The adjuster 2 is used to drive the handle 1 and / or the second lens frame 4 to rotate relative to the first lens frame 3. The central axis of rotation of the handle 1 relative to the first lens frame 3 and / or the central axis of rotation of the second lens frame 4 relative to the first lens frame 3 are both arranged intersecting the first direction R1.

[0042] For example, a reflector is mounted on a first frame 3. A focusing lens is mounted on a second frame 4. The focusing lens is used to focus the light reflected by the reflector.

[0043] For example, a focusing lens is used to focus the laser reflected by the mirror.

[0044] Handle 1 is for the operator to hold so as to laser-activate the cleaning solution in the root canal by holding handle 1.

[0045] For example, the central axis of rotation of the handle 1 relative to the first frame 3 is arranged to intersect with the first direction R1, and the central axis of rotation of the second frame 4 relative to the first frame 3 is arranged to intersect with the first direction R1.

[0046] For example, the central axis of rotation of the handle 1 relative to the first frame 3 is perpendicular to the first direction R1. The central axis of rotation of the second frame 4 relative to the first frame 3 is also perpendicular to the first direction R1.

[0047] For example, the adjustment member drives the handle 1 to rotate relative to the first frame 3, and the central axis of the rotation of the handle 1 relative to the first frame 3 is arranged to intersect with the first direction R1.

[0048] For example, the adjusting member drives the second frame 4 to rotate relative to the first frame 3, and the central axis of the rotation of the second frame 4 relative to the first frame 3 is arranged to intersect with the first direction R1.

[0049] The light guide mirror points to the focal point of the light guide mirror in the approximate direction of light output, which is also roughly along the direction from the focusing mirror to the focal point of the focusing mirror, and roughly from the reflecting mirror to the focusing mirror.

[0050] For example, the light emission direction is approximately from the first frame 3 to the second frame 4.

[0051] For example, the handle 1 receives incident light, the incident light acting on the reflector propagates within the handle 1 approximately along the first direction R1 to the reflector and is reflected by the reflector to form outgoing light, and the focusing lens focuses the outgoing light reflected by the reflector.

[0052] In this embodiment, the adjuster 2 drives the handle 1 and / or the second frame 4 to rotate relative to the first frame 3. Since the central axes of rotation of the handle 1 and / or the second frame 4 relative to the first frame 3 are both intersecting the first direction R1, rotation of either the handle 1 or the second frame 4 relative to the first frame 3 will cause a change in the angle between the approximate light output direction from the reflecting mirror to the focusing mirror and the first direction R1. The approximate light output direction from the reflecting mirror to the focusing mirror is adjustable relative to the first direction R1. This allows the operator to hold the handle 1 at a suitable angle for root canal cleaning, making the operation flexible and convenient.

[0053] It is understood that the specific structure of the frame assembly 5 is not limited. For example, the frame assembly 5 includes a first frame 3 but does not include a second frame 4, and the mirror mounted on the first frame 3 is capable of both reflecting and focusing light.

[0054] In some embodiments, please refer to Figures 1-10 The direction in which the handle 1 rotates relative to the first frame 3 is the first rotation direction R3, and the direction in which the second frame 4 rotates relative to the first frame 3 is the second rotation direction R4. The first rotation direction R3 and the second rotation direction R4 are opposite.

[0055] For example, the first rotation direction R3 and the second rotation direction R4 are opposite, and the light output direction from the reflecting mirror to the focusing mirror and the first direction R1 can be moved closer or further apart by rotation.

[0056] For example, the first rotation direction R3 is the rotation direction of the handle 1, and the second rotation direction R4 is the rotation direction of the second frame 4.

[0057] In this embodiment, the reflector is mounted on the first frame 3, and the handle 1 receives the incident light from the light guide device. Rotation of the handle 1 relative to the first frame 3 adjusts the angles of the incident and outgoing light from the reflector. The focusing lens is mounted on the second frame 4. Rotation of the second frame 4 relative to the first frame 3 adjusts the position of the focusing lens relative to the reflector, allowing the focusing lens to better receive and focus the light reflected from the reflector. Since the first rotation direction R3 and the second rotation direction R4 are opposite, driving the handle 1 and the second frame 4 to rotate relative to the first frame 3 via the adjuster 2 not only changes the angles of the incident and outgoing light from the reflector but also adjusts the position of the focusing lens, enabling it to better receive and focus the outgoing light with its changed angle, thus placing the focusing lens as close as possible to the position where it receives the reflected light from the reflector.

[0058] It is understood that the arrangement of the first rotation direction R3 and the second rotation direction R4 is not limited. For example, the first rotation direction R3 and the second rotation direction R4 can be the same.

[0059] In some embodiments, please refer to Figures 1-10 The adjuster 2 includes a mounting bracket 21, an adjusting wheel 22, a first follower 23, and a second follower 24. The mounting bracket 21 is connected to the first frame 3. The adjusting wheel 22 is rotatably connected to the mounting bracket 21. The first follower 23 includes a first drive wheel 231 rotatably connected to the mounting bracket 21, the axis of which is arranged intersecting the axis of the adjusting wheel 22, and the handle 1 rotates with the first drive wheel 231. The second follower 24 includes a second drive wheel 241 rotatably connected to the mounting bracket 21, the axis of which is arranged intersecting the axis of the adjusting wheel 22, and the second frame 4 rotates with the second drive wheel 241. The adjusting wheel 22 drives the first drive wheel 231 and the second drive wheel 241 to rotate together, the rotation direction of the first drive wheel 231 being opposite to that of the second drive wheel 241.

[0060] For example, please refer to Figures 1-10 The mounting bracket 21 has a shell-like structure.

[0061] For example, the mounting bracket 21 can be a solid structure.

[0062] For example, the mounting bracket 21 is generally spherical in shape.

[0063] For example, the mounting frame 21 has a mounting cavity 211, the adjusting wheel 22 is partially located in the mounting cavity 211, the adjusting wheel 22 has an adjusting shaft 221, the adjusting shaft 221 is rotatably connected to the cavity wall of the mounting cavity 211, the adjusting shaft 221 passes through the cavity wall of the mounting cavity 211, and the end of the adjusting shaft 221 facing away from the mounting cavity 211 protrudes outside the mounting frame 21.

[0064] For example, please refer to Figures 1-10 The end of the adjusting shaft 221 facing away from the mounting cavity 211 has an adjusting cavity 222 protruding from the outside of the mounting bracket 21. The cross-sectional shape of the adjusting cavity 222 is hexagonal. That is, the adjusting cavity 222 of the adjusting shaft 221 has an internal hexagonal structure. When an internal hexagonal wrench is placed into the adjusting cavity 222, the adjusting shaft 221 can be rotated by the limiting of the adjusting cavity 222, thereby driving the adjusting wheel 22 to rotate. The adjusting wheel 22 drives the first driven member 23 and the second driven member 24 to rotate together.

[0065] For example, the adjusting shaft 221 may protrude from the outside of the mounting bracket 21. The cross-sectional shape of the outer contour of the adjusting shaft 221 is polygonal. The adjusting shaft 221 and the adjusting wheel 22 can be rotated using a common open-end wrench. The adjusting shaft 221 can also be rotated by hand.

[0066] For example, the regulator 2 also includes a driver, which drives the regulating wheel 22 to rotate so that automatic adjustment can be achieved.

[0067] During the rotation of the adjusting wheel 22, it will drive the first transmission wheel 231 and the second transmission wheel 241 to rotate together.

[0068] For example, the handle 1 rotates with the first transmission wheel 231, and the handle 1 is connected to the first transmission wheel 231.

[0069] For example, the handle 1 is key-connected to the first drive wheel 231.

[0070] For example, the handle 1 is bolted to the first drive wheel 231.

[0071] For example, the handle 1 is integrally formed with the first drive wheel 231.

[0072] For example, the second frame 4 rotates following the second drive wheel 241, and the second frame 4 is connected to the second drive wheel 241.

[0073] For example, the second frame 4 is keyed to the second drive wheel 241.

[0074] For example, the second frame 4 is bolted to the second drive wheel 241.

[0075] For example, the second frame 4 is integrally formed with the second drive wheel 241.

[0076] For example, please refer to Figures 1-10 The handle 1 is rotatably connected to the mounting bracket 21, and the first transmission wheel 231 is connected to the handle 1.

[0077] For example, please refer to Figures 1-10 The second frame 4 is rotatably connected to the mounting bracket 21, and the second drive wheel 241 is connected to the second frame 4.

[0078] In this embodiment, the mounting bracket 21 provides mounting support for the adjusting wheel 22, the first driven member 23, and the second driven member 24. The rotation of the adjusting wheel 22 relative to the mounting bracket 21 drives the first transmission wheel 231 and the second transmission wheel 241 to rotate together in opposite directions, causing the corresponding handle 1 and the second mirror frame 4 to rotate accordingly. This changes the incident angle and reflection angle of the mirror on the first mirror frame 3 connected to the mounting bracket 21, as well as the position of the focusing lens on the second mirror frame 4 relative to the mirror. While changing the light output direction, it also ensures that the focusing lens remains as close as possible to the propagation path of the reflected light from the mirror, effectively focusing the reflected light. The axial arrangement of the first transmission wheel 231 and the adjusting wheel 22 is intersecting, which facilitates driving the adjusting wheel 22 to rotate and drive the first and second transmission wheels 231 and 241 with minimal interference from the first and second transmission wheels 231 and 241.

[0079] It is understood that the specific structure of the adjuster 2 is not limited. For example, the adjuster 2 may not have an adjusting wheel 22; instead, it can drive the first transmission wheel 231 and the second transmission wheel 241 to rotate together via a linkage mechanism. For example, the handle 1 can be directly driven to rotate relative to the first frame 3 via a corresponding driver, or the second frame 4 can be directly driven to rotate relative to the first frame 3 via a corresponding driver.

[0080] In some embodiments, please refer to Figures 1-10 The first transmission wheel 231 and the second transmission wheel 241 are respectively arranged on opposite sides of the radial direction of the adjusting wheel 22, and the first transmission wheel 231 and the second transmission wheel 241 are both located on the same side of the adjusting wheel 22 along the axial direction of the adjusting wheel 22.

[0081] For example, the reflector and the focusing lens are both located on the same side of the adjusting wheel 22 along the axial direction of the adjusting wheel 22.

[0082] For example, the first transmission wheel 231 and the second transmission wheel 241 are both located on the side of the adjusting wheel 22 facing the reflector along the axial direction of the adjusting wheel 22.

[0083] For example, the first drive wheel 231 and the second drive wheel 241 are arranged coaxially.

[0084] In this embodiment, the first transmission wheel 231 and the second transmission wheel 241 are respectively arranged on opposite sides of the radial direction of the adjusting wheel 22. The first transmission wheel 231 and the second transmission wheel 241 are both located on the same side of the adjusting wheel 22 along the axial direction of the adjusting wheel 22. This arrangement can make full use of the space on both sides of the radial direction of the adjusting wheel 22 to arrange the first transmission wheel 231 and the second transmission wheel 241. The adjusting wheel 22 bears the loads of the first transmission wheel 231 and the first transmission wheel 241 respectively on opposite sides of the radial direction of the adjusting wheel 22, which is beneficial to the adjusting wheel 22 bearing the load more evenly on opposite sides of the radial direction of the adjusting wheel 22.

[0085] It is understood that the arrangement of the first drive wheel 231 and the second drive wheel 241 is not limited. Exemplarily, the first drive wheel 231 and the second drive wheel 241 may be located on the same side of the adjusting wheel 22 along its radial direction. Exemplarily, the first drive wheel 231 and the second drive wheel 241 may be located on opposite sides of the adjusting wheel 22 along its axial direction.

[0086] In some embodiments, please refer to Figures 1-10 The adjusting wheel 22, the first transmission wheel 231, and the second transmission wheel 241 are all bevel gears, and the adjusting wheel 22 meshes with the first transmission wheel 231 and the second transmission wheel 241 respectively.

[0087] In this embodiment of the present disclosure, the adjusting wheel 22 can directly drive the first transmission wheel 231 and the second transmission wheel 241 to rotate through the meshing of bevel gears.

[0088] It is understood that the specific structure of the first transmission wheel 231 and the second transmission wheel 241 is not limited. For example, the adjusting wheel 22, the first transmission wheel 231, and the second transmission wheel 241 can be spur gears. A corresponding transmission rod can be provided between the adjusting wheel 22 and the first transmission wheel 231. A corresponding rack is provided on both the side of the corresponding transmission rod facing the adjusting wheel 22 and the side of the corresponding transmission rod facing the first transmission wheel 231. The adjusting wheel 22 and the first transmission wheel 231 mesh with the corresponding racks. Alternatively, a corresponding connecting rod can be provided between the adjusting wheel 22 and the second transmission wheel 241. A corresponding rack is provided on both the side of the corresponding transmission rod facing the adjusting wheel 22 and the side of the corresponding transmission rod facing the second transmission wheel 241. The adjusting wheel 22 and the second transmission wheel 241 mesh with the corresponding racks.

[0089] In some embodiments, please refer to Figures 1-10 The first frame 3 has a first mounting portion 31 for mounting a reflector, and the second frame 4 has a second mounting portion 41 for mounting a focusing lens. The adjusting wheel 22 is located on the side of the first mounting portion 31 away from the second mounting portion 41.

[0090] For example, one end of the adjusting wheel 22 is rotatably connected to the mounting bracket 21, and the other end of the adjusting wheel 22 is suspended in the air.

[0091] For example, one end of the adjusting wheel 22 is rotatably connected to the mounting bracket 21, and the other end of the adjusting wheel 22 is rotatably connected to the first mirror frame 3.

[0092] In this embodiment, since the adjusting wheel 22 is located on the side of the first mounting part 31 away from the second mounting part 41, the adjusting wheel 22 is on the side of the reflector away from the focusing lens, which helps to reduce the interference of the adjusting wheel 22 on the incident light and outgoing light of the reflector.

[0093] It is understood that the arrangement of the adjusting wheel 22 is not limited. For example, the adjusting wheel 22 may be located on the side of the first mounting portion 31 facing the second mounting portion 41.

[0094] In some embodiments, please refer to Figures 1-10 The mounting bracket 21 has a mounting cavity 211. The first drive wheel 231 and the second drive wheel 241 are both located at least partially in the mounting cavity 211. The cavity wall of the mounting cavity 211 has a relief groove 212. The handle 1 and the second frame 4 pass through the relief groove 212 and move within the corresponding relief groove 212.

[0095] For example, both the first drive wheel 231 and the second drive wheel 241 are located inside the mounting cavity 211.

[0096] For example, the clearance groove 212 extends circumferentially along the first drive wheel 231.

[0097] For example, the first drive wheel 231 and the second drive wheel 241 are respectively arranged on opposite sides of the radial direction of the adjusting wheel 22, and the first frame 3 is located between the first drive wheel 231 and the second drive wheel 241 along the radial direction of the adjusting wheel 22.

[0098] In this embodiment, the handle 1 extends into the mounting cavity 211 to rotate with the first transmission wheel 231. The handle 1 moves within the corresponding clearance groove 212, allowing it to avoid interference with the first transmission wheel 231 during rotation. Similarly, the second frame 4 extends into the mounting cavity 211 to rotate with the second transmission wheel 241. The second frame 4 moves within the corresponding clearance groove 212, preventing interference with the mounting frame 21 during rotation. These clearance grooves effectively reduce interference between the handle 1 and the first frame 3 and the mounting frame 21 during rotation.

[0099] It is understood that the structure of the mounting bracket 21 is not limited. For example, the adjusting wheel 22, the first transmission wheel 231 and the second transmission wheel 241 are all located outside the mounting bracket 21, and the mounting bracket 21 may not have the clearance groove 212.

[0100] In some embodiments, please refer to Figures 1-10 The mounting frame 21 has a mounting cavity 211, the first lens frame 3 is located inside the mounting cavity 211, and the second lens frame 4 has a second mounting part 41 for mounting a focusing lens. The second mounting part 41 is located outside the mounting frame 21. The cavity wall of the mounting cavity 211 has a light-transmitting hole 213, which extends circumferentially along the second drive wheel 241 and is located between the first mounting part 31 and the second mounting part 41.

[0101] The first mirror frame 3 is located inside the mounting cavity 211, and the reflector mounted on the first mirror frame 3 is also located inside the mounting cavity 211.

[0102] The light-transmitting hole 213 is located between the first mounting part 31 and the second mounting part 41. The light reflected by the mirror mounted on the first mounting part 31 of the first mirror frame 3 in the mounting cavity 211 will be transmitted to the focusing lens through the light-transmitting hole 213.

[0103] In this embodiment of the present disclosure, during the rotation of the adjusting wheel 22, the angle of the reflected light from the reflector changes. The light extends circumferentially along the second transmission wheel 241 through the light-transmitting hole 213, so that the reflected light that changes within a certain angle range can pass through the light-transmitting hole 213 and propagate to the focusing lens, reducing the possibility of the reflected light being blocked.

[0104] It is understood that the arrangement of the first mirror frame 3 is not limited. Exemplarily, the first mirror frame 3 may be outside the mounting bracket 21. Exemplarily, the reflector may be outside the mounting bracket 21.

[0105] In some embodiments, please refer to Figures 1-10 The handle 1 includes a main body 11 and a support wall 12. The adjuster 2 is located at one end of the main body 11 along its length. The support wall 12 is connected to the main body 11, and the adjuster 2 is disposed on the support wall 12. The support wall 12 is located on one side of the main body 11 along a second direction R2, which is arranged intersecting with the first direction R1.

[0106] For example, the main body 11 and the regulator 2 are arranged at intervals.

[0107] For example, the support wall 12 is connected to the first drive wheel 231.

[0108] For example, the main body 11, the support wall 12 and the first transmission wheel 231 are integrally formed.

[0109] For example, please refer to Figures 1-10The support wall 12 penetrates the clearance groove 212.

[0110] For example, the first direction R1 and the second direction R2 are perpendicular.

[0111] In this embodiment, the support wall 12 is located on one side of the main body 11 along the second direction R2, and the adjuster 2 can be positioned as close as possible to the middle of the main body 11 along the second direction R2, reducing the degree to which the adjuster 2 is suspended from the main body 11. When the adjuster 2 is deformed by external load, the main body 11 can support the adjuster 2 to a certain extent, reducing the possibility of damage to the hand tool.

[0112] The above are merely preferred embodiments of this application and are not intended to limit the scope of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
