Description
Technical Field
[0001] The utility model relates to optoelectronic technology and application fields, in particular to a multi-light path switching system and a laser oral treatment instrument. Background Art
[0002] Laser dental treatment devices generally consist of a main unit, a laser fiber, a treatment handpiece, and a switch. The main unit includes a laser, laser power supply, control system, indicator light system, and cooling system. Among these, laser dental treatment devices using Nd:YAG solid-state lasers are the most widely used, demonstrating significant advantages in gingival resection and shaping procedures, root canal disinfection, periodontitis treatment, and peri-implantitis treatment. Different oral conditions or treatment stages typically require light spots of varying diameters for optimal treatment efficacy and efficiency. To achieve these different spot sizes, coupling fibers of varying diameters are required. However, existing single beam transmission paths cannot couple fibers with multiple core diameters, making it impossible to achieve a wide range of spot sizes, making it difficult to meet the needs of the entire treatment process. To meet the varying needs of the entire procedure, doctors often need to swap fibers with different core diameters during treatment and then reassemble them with the treatment handpiece. This increases treatment cost and complexity, increases treatment time, and exacerbates patient discomfort. Utility Model Content

In addition, several of the optical path switching modules are arranged in a tree-like multi-level arrangement, which enables the laser beam, which has changed its optical path after reflection in the previous level, to enter the next level and then reflect and change its optical path again, thereby generating more optical path switching paths. The modular design of the optical path switching modules facilitates installation and replacement, and the appropriate number of optical path switching modules can be installed according to actual needs to obtain an optical path switching system with different paths.

DETAILED DESCRIPTION
[0022] Example 1
[0023] Existing laser oral treatment devices have a single internal optical path and can only couple one optical fiber, making it difficult to meet the differentiated requirements of different oral disease treatment plans and the different optical fiber core diameters required for the entire surgical procedure. To this end, the inventors proposed a multi-optical path switching system that uses an optical path switching module to adjust the laser deflection, thereby realizing an optical path conversion system with multiple freely switchable outputs. A movable reflector is provided in the optical path switching module, and the light emitted by the laser can be selectively output in multiple optical paths by adjusting the position of the reflector. Each optical path is coupled and transmitted with optical fibers of different core diameters, so that a variety of laser switching outputs with different spot diameters can be obtained.
[0024] A multi-optical path switching system includes a plurality of optical path switching modules, wherein the plurality of optical path switching modules are arranged in a tree-like multi-level arrangement so that the outgoing light of the upper-level optical path switching module serves as the incident light of the lower-level optical path switching module. The optical path switching module includes a slide, an incident reflector, and an exit reflector. The incident reflector is fixedly connected to the slide, and the exit reflector is fixedly mounted in the extension direction of the sliding direction of the slide, and the angles of the exit reflector and the incident reflector satisfy a certain relationship, so that the light beam irradiated on the incident reflector is reflected onto the exit reflector, and changes its optical path after being reflected by the exit reflector. The sliding slide changes the position of the incident reflector, so that the light beam can pass directly without reflection, or the light beam can change its optical path after being reflected, thereby realizing that a single optical path switching module outputs two optical paths. Multi-optical path switching can be realized by stacking multiple optical path switching modules.
[0025] See also Figure 1 In this embodiment, a three-optical path switching system is provided, including two optical path switching modules, namely a first optical path switching module and a second optical path switching module.
[0026] The first optical path switching module includes a first slide 11, a first incident reflector 12 and a first exit reflector 13. The sliding direction of the first slide 11 is a vertical direction, which is used to drive the first incident reflector 12 to move in the vertical direction. The first incident reflector 12 is fixedly connected to the first slide 11, and the first exit reflector 13 is fixedly installed above the sliding direction of the first slide 11. The angles of the first incident reflector 12 and the first exit reflector 13 are not limited, and only need to ensure that the incident light can be reflected by the first incident reflector 12 and illuminate the first exit reflector 13. Preferably, the first exit reflector 13 is parallel to the first incident reflector 12, so that after the incident light is reflected by the first incident reflector 12 and the first exit reflector 13, an exit light parallel to the original optical path is obtained.
[0027] The second optical path switching module includes a second slide 21, a second incident reflector 22 and a second exit reflector 23. The second slide 21 is installed on the right side of the first slide 11, and the sliding direction of the second slide 21 is parallel to the sliding direction of the first slide 11, and is used to drive the second incident reflector 22 to move. The second incident reflector 22 is fixed on the second slide 21, and the second exit reflector 23 is fixed below the sliding direction of the second slide 21. The angles of the second incident reflector 22 and the second exit reflector 23 are not limited, and only need to ensure that the light beam can be reflected by the second incident reflector 22 and irradiated on the second exit reflector 23. Preferably, the second exit reflector 23 is parallel to the second incident reflector 22, so that after the incident light is reflected by the second incident reflector 22 and the second exit reflector 23, an exit light parallel to the original optical path is obtained.
[0028] Optionally, the incident reflector and the output reflector are fully reflective mirrors made of K9 glass with a size of Φ30mm. The reflective surface is coated with a fully reflective film HR@1064nm to obtain the best beam reflection effect.
[0029] Preferably, each of the first slide 11 and the second slide 21 includes a fixed base 2 and a movable platform 3. The movable platform 3 is slidably mounted on the fixed base 2, and the incident reflector is fixedly connected to the movable platform 3. By sliding the movable platform 3, the position of the incident reflector can be smoothly changed to avoid displacement of the incident reflector caused by vibration during movement.
[0030] More preferably, the first slide 11 and the second slide 21 further include a driving member 4. The driving member 4 is respectively installed on one side of the first slide 11 and the second slide 21 and is connected to the mobile platform 3 for driving the mobile platform 3 to slide, accurately control the moving position, and improve the accuracy of the device.
[0031] More preferably, the first slide 11 and the second slide 21 further include limit switches 5, which are mounted on either side of the fixed base 2 and are used to limit the sliding movement of the mobile platform 3 driven by the driver 4. When the mobile platform 3 slides to the end, the limit switch 5 is pressed to conduct, and the driver 4 stops working after receiving the electrical signal, ensuring that the mobile slide 3 stays in the correct position and further improving accuracy.
[0032] See also Figure 2 When in use, the first slide 11 slides to the upper limit, and the second slide 21 is positioned at any position, so that the laser beam incident from the left is reflected by the first incident reflector 12 and the first exit reflector 13 respectively, and obtains the first output light path. The first slide 11 slides to the lower limit, and the second slide 21 slides to the upper limit, so that the laser beam incident from the left does not irradiate any reflector, and directly passes through the first light path switching module and the second light path switching module, thereby obtaining the second output light path. The first slide 11 slides to the lower limit, and the second slide 12 slides to the lower limit, so that the laser beam incident from the left is reflected by the second incident reflector 22 and the second exit reflector 23 respectively, and obtains the third output light path.
[0033] Example 2
[0034] This embodiment provides a four-optical path switching system, comprising three optical path switching modules: a first optical path switching module, a second optical path switching module, and a third optical path switching module. The configurations of the first and second optical path switching modules are the same as those in Example 1. Therefore, the four-optical path switching system can be considered the three-optical path switching system described in Example 1, with the addition of a third optical path switching module.
[0035] The third optical path switching module includes a third slide 31, a third incident reflector 32 and a third exit reflector 33. The third slide 31 is installed on the right side of the first exit reflector 13, and the sliding direction of the third slide 31 is also vertical, which is used to drive the third incident reflector 32 to move. The third incident reflector 32 is fixed on the third slide 31, and the third exit reflector 33 is fixed above the sliding direction of the third slide 31. The angle between the third incident reflector 32 and the third exit reflector 33 is not limited, and it only needs to ensure that the light beam can be reflected by the third incident reflector 32 and illuminate the third exit reflector 33. Preferably, the third exit reflector 33 is parallel to the third incident reflector 32, so that after the incident light is reflected by the third incident reflector 32 and the third exit reflector 33, an exit light parallel to the original optical path is obtained.
[0036] See also Figure 3When in use, slide the first slide 11 to the upper limit, the second slide 21 is positioned at any position, and the third slide 31 is moved to the upper limit. The laser beam incident from the left side is reflected by the first incident reflector 12, the first exit reflector 13, the third incident reflector 32, and the third exit reflector 33, respectively, to obtain the first output optical path. Based on the above settings, slide the third slide 31 to the lower limit. The laser beam incident from the left side is reflected by the first incident reflector 12 and the first exit reflector 13, respectively, to obtain the second output optical path. Slide the first slide 11 to the lower limit, the second slide 21 to the upper limit, and the third slide 31 is positioned at any position. The laser beam incident from the left side is not reflected by any reflector and propagates in a straight line along the original optical path to leave the optical path switching system, thereby obtaining the third output optical path. Slide the first slide 11 to the lower limit position, the second slide 21 also slides to the lower limit position, and the third slide 31 is positioned at any position. The laser beam incident from the left is reflected by the second incident reflector 22 and the second output reflector 23 to obtain the fourth output light path.
[0037] Example 3
[0038] This embodiment provides a five-light path switching system, which is obtained by adding a fourth light path switching module to the four-light path switching system of Example 2. The fourth light path switching module includes a fourth slide 41, a fourth incident reflector 42, and a fourth exit reflector 43. The fourth slide 41 is mounted to the right of the second exit reflector 23, and the fourth slide 41 slides in a vertical direction, used to drive the fourth incident reflector 42 to move. The fourth incident reflector 42 is fixed to the fourth slide 41, and the fourth exit reflector 43 is fixed below the sliding direction of the fourth slide 41. The angle between the fourth incident reflector 42 and the fourth exit reflector 43 is not limited, and only needs to ensure that the light beam can be reflected by the fourth incident reflector 42 and illuminate the fourth exit reflector 43. Preferably, the fourth exit reflector 43 is parallel to the fourth incident reflector 42, so that after the incident light is reflected by the fourth incident reflector 42 and the fourth exit reflector 43, the exit light is parallel to the original light path.
[0039] See also Figure 4When in use, slide the first slide 11 to the upper limit, slide the third slide 31 to the upper limit, and the second slide 21 and the fourth slide 41 are positioned at any position. The laser beam incident from the left is reflected by the first incident reflector 12, the first exit reflector 13, the third incident reflector 32, and the third exit reflector 33, respectively, to obtain the first output optical path. Based on the above settings, slide the third slide 31 to the lower limit, and the laser beam incident from the left is reflected by the first incident reflector 12 and the first exit reflector 13, respectively, to obtain the second output optical path. Slide the first slide 11 to the lower limit, slide the second slide 21 to the upper limit, and the third slide 31 and the fourth slide 41 are positioned at any position. The laser beam incident from the left is not reflected by any reflector and propagates in a straight line along the original optical path to leave the optical path switching system, thereby obtaining the third output optical path. Slide the first slide 11 to the lower limit position, the second slide 21 also to the lower limit position, the fourth slide 41 to the upper limit position, and the third slide 31 to any position. The laser beam incident from the left is reflected by the second incident reflector 22 and the second exit reflector 23 to obtain a fourth output optical path. Based on the above fourth output optical path, slide the fourth slide 41 to the lower limit position. The laser beam incident from the left is reflected by the second incident reflector 22, the second exit reflector 23, the fourth incident reflector 42, and the fourth exit reflector 43 to obtain a fifth output optical path.
[0040] Example 4
[0041] The present invention also provides a laser oral treatment device, including the above-mentioned multi-optical path switching system. Exemplarily, the three-optical path switching system of Example 1 is taken as an example for further explanation. The three-optical path switching system is installed in the laser oral treatment device, and the laser beam emitted by the laser enters the three-optical path switching system as the incident light. The first output optical path of the three-optical path switching system is coupled with an optical fiber with a radius of 200μm, the second output optical path is coupled with an optical fiber with a radius of 300μm, and the third output optical path is coupled with an optical fiber with a radius of 945μm. By controlling the three-optical path switching system, the laser beam is output from optical fibers of different radii after the optical path is changed by the optical path switching system, thereby obtaining light spots of different sizes. The laser oral treatment device described in the present invention can meet the needs of almost all treatment plans. The entire operation process does not require the disassembly and assembly of treatment tools. Different light spots can be obtained by directly adjusting the optical path switching system, which effectively reduces the difficulty of operation and simplifies the overall procedure.
