Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a laser therapy device for oral treatment. Background Technology

[0002] As a new technology in the dental field, lasers have attracted much attention. The laser's optical fibers are flexible and thin, and can easily enter the periodontal pockets and any area inside the oral cavity. The 1064nm wavelength laser has the characteristics of moderate penetration depth into human tissue and moderate heat generation. Using low-energy lasers, capillaries in the oral cavity can be effectively sealed off, and bacterial proteins can be decomposed and denatured, achieving the effects of reducing swelling, stopping bleeding, and killing bacteria.

[0003] In existing technologies, when using laser therapy devices to treat oral problems, the laser treatment pen on the main body of the device needs to be in direct contact with the patient's oral cavity. This can lead to contamination of the laser treatment pen by the patient's oral cavity. Therefore, to prevent cross-infection among patients, the laser treatment pen needs to be thoroughly disinfected after use. However, existing laser therapy devices do not have suitable accessories for storing the laser treatment pen, causing it to become contaminated with impurities or bacteria during storage, which can endanger the patient's health during treatment. Furthermore, to ensure the laser treatment pen's range of motion, the connecting wires are relatively long, making it prone to being stepped on or pulled during use, potentially causing the laser treatment pen to fall to the ground and cause contamination. Therefore, a laser therapy device for oral treatment is needed to meet these needs. Summary of the Invention

[0004] The purpose of this invention is to provide a laser therapy device for oral treatment, in order to solve the problem mentioned in the background art that existing laser therapy devices do not have suitable accessories for storing the laser therapy pen, which leads to the laser therapy pen becoming contaminated with impurities or bacteria during storage, thereby endangering the patient's health during treatment. At the same time, in order to ensure the range of motion of the laser therapy pen, the connecting wire on the laser therapy pen is relatively long, which is prone to being stepped on and pulled during use, and may even cause the laser therapy pen to be pulled to the ground, causing pollution.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a laser therapy device for oral treatment, comprising a laser therapy device body, a control panel on the laser therapy device body, a wire movably mounted on the laser therapy device body, a laser therapy pen fixedly mounted at the end of the wire, a fixed mounting base movably mounted on the top side of the laser therapy device body, a movable sterilization sleeve movably mounted on the fixed mounting base, an ultraviolet lamp movably mounted on the inner wall of the movable sterilization sleeve, and the laser therapy pen movably mounted inside the movable sterilization sleeve.

[0006] This technical solution includes a laser treatment device for oral treatment. After the laser treatment pen is disinfected, it can be installed in a movable disinfection sleeve, providing a suitable storage space for the laser treatment pen and avoiding direct contact with the external environment. At the same time, the installation slot is used for periodic disinfection to prevent bacteria from growing on the laser treatment pen, thereby ensuring that the patient's health will not be harmed during treatment and improving the practicality of the device.

The wire is movably sleeved on the rotating rod. A fixed mounting plate is fixedly installed on the wire winding box. A servo motor is fixedly installed on the fixed mounting plate. A transmission rod is fixedly installed on the output end of the servo motor. The transmission rod is rotatably installed on the wire winding box. One end of the transmission rod is adapted to the rotating rod. Through holes are opened on both sides of the wire winding box, and the two ends of the wire pass through the two through holes respectively.

[0008] Preferably, the rotating rod also has a rotation limiting groove at one end near the wire winding box, and a limiting ring is rotatably installed in the rotation limiting groove. The limiting ring is fixedly installed on the inner wall of the wire winding box.

[0009] Preferably, a fixed ring plate is fixedly installed on the rotating rod, and a movable sleeve is slidably installed on the transmission rod. Two fixed blocks and two double rotating top blocks are fixedly installed at the ends of the movable sleeve and the fixed ring plate that are close to each other. The two double rotating top blocks are in contact with the two fixed blocks respectively. A positioning spring is movably sleeved on the transmission rod. One end of the positioning spring is in contact with the movable sleeve, and the other end of the positioning spring is in contact with the inner wall of the wire winding box.

[0010] Preferably, the inner wall of the movable sleeve has two limiting grooves, and a limiting slide shaft is slidably installed in each of the two limiting grooves. Both limiting slide shafts are fixedly installed on the outside of the transmission rod.

[0011] Preferably, the fixed mounting base has two mounting slots, and a movable rod is slidably installed in each of the two mounting slots. The two movable rods are fixedly installed on the bottom side of the movable disinfection sleeve. Pressure blocks are fixedly installed on the bottom side of each of the two mounting slots, and the two pressure blocks are in contact with the two movable rods respectively.

[0012] Preferably, the inner wall of the active disinfection sleeve has two mounting holes, and a mounting slider is slidably installed in each of the two mounting holes. An arc-shaped fixing plate is fixedly installed at the end of the two mounting sliders that are close to each other. Both arc-shaped fixing plates are in contact with the surface of the laser treatment pen. A driven rod is rotatably installed on each of the two arc-shaped fixing plates, and a driving rod is rotatably installed on the side of the two driven rods that are close to each other.

[0013] Preferably, a limiting groove is provided on the mounting slider, a limiting rod is slidably installed in the limiting groove, the limiting rod is fixedly installed on the inner wall of the mounting hole, and a fixing spring is movably sleeved on the limiting rod. One end of the fixing spring is fixedly installed on the inner wall of the mounting hole, and the other end of the fixing spring is fixedly installed on the mounting slider.

[0014] Preferably, two fixing plates are fixedly installed on both sides of the fixed mounting base, and positioning bolts are threaded on all four fixing plates. The four positioning bolts are respectively threaded on the top side of the main body of the laser therapy instrument.

[0015] Preferably, both ends of the driven rod are provided with driven holes, and a driven shaft is rotatably installed in each of the two driven holes. The two driven shafts are respectively fixedly installed on the arc-shaped fixed clamp and the drive rod.

[0016] The beneficial effects of this invention are: In this invention, by using a movable disinfection sleeve and an installation slot, the laser treatment pen can be installed inside the movable disinfection sleeve after disinfection, thus providing a suitable storage space for the laser treatment pen and avoiding direct contact with the external environment. At the same time, the installation slot is used for intermittent disinfection to prevent bacteria from growing on the laser treatment pen, thereby ensuring that the patient's health will not be harmed during treatment and improving the practicality of the device.

[0017] In this invention, by setting up a wire winding box, when the wire is relatively long, a servo motor can be used to drive a rotating rod to rotate when excessive length is not needed, thereby achieving the purpose of winding the wire. This limits the length of the wire and prevents the laser treatment pen from being pulled or dragged by external footsteps or pulls, causing it to fall to the ground and cause pollution, thus further ensuring the hygiene of the laser treatment pen.

[0018] In this invention, by setting up arc-shaped fixing clamps, when placing the laser treatment pen on the movable sterilization sleeve, two arc-shaped fixing clamps work together to fix the laser treatment pen inside the movable sterilization sleeve, preventing the laser treatment pen from accidentally falling off due to shaking, and facilitating the user's operation.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0022] Reference Figure 1-7A laser therapy device for oral treatment includes a laser therapy device body 1, a control panel 2 on the laser therapy device body 1, a wire 3 movably mounted on the laser therapy device body 1, a laser therapy pen 4 fixedly mounted at the end of the wire 3, a fixed mounting base 5 movably mounted on the top side of the laser therapy device body 1, a movable disinfection sleeve 6 movably mounted on the fixed mounting base 5, an ultraviolet lamp 12 movably mounted on the inner wall of the movable disinfection sleeve 6, and the laser therapy pen 4 movably mounted inside the movable disinfection sleeve 6. After the device is used, the laser therapy pen 4 needs to be placed inside the movable disinfection sleeve 6 to adjust the position of the movable drive rod 608. The drive rod 608 drives two driven rods 607 to move by the cooperation of the driven holes 609 and driven shafts 610 on both sides. The two moving driven rods 607 drive two... With the arc-shaped fixing plates 606 moving away from each other, one end of the laser treatment pen 4 can be placed between the two arc-shaped fixing plates 606. As the arc-shaped fixing plates 606 move, the mounting slider 602 slides within the mounting hole 601, allowing the mounting slider 602 to slide on the limiting rod 604 using the limiting groove 603. Since the mounting slider 602 compresses the fixing spring 605 while sliding, after releasing the drive rod 608, the fixing spring 605 can drive the two mounting sliders 602 to move, thereby bringing the two arc-shaped fixing plates 606 closer together and fixing the laser treatment pen 4 between the two arc-shaped fixing plates 606. At this time, due to the change in the overall weight of the movable sterilization sleeve 6, the movable rod 502 slides within the mounting groove 501, thereby triggering the pressure block 503, which in turn activates the servo motor 10.

[0023] Reference Figure 1-4Furthermore, a wire winding box 7 is fixedly installed on one side of the main body 1 of the laser therapy instrument. A rotating rod 8 is rotatably installed on the inner wall of the wire winding box 7. The wire 3 is movably sleeved on the rotating rod 8. A fixed mounting plate 9 is fixedly installed on the wire winding box 7. A servo motor 10 is fixedly installed on the fixed mounting plate 9. A transmission rod 11 is fixedly installed on the output end of the servo motor 10. The transmission rod 11 is rotatably installed on the wire winding box 7. One end of the transmission rod 11 is adapted to the rotating rod 8. Through holes 70 are opened on both sides of the wire winding box 7. 1. The two ends of the wire pass through two through holes 701 respectively. Because the wire 3 connected to the laser treatment pen 4 is relatively long, it is easy to be stepped on or pulled during use, and may even be pulled and dropped to the ground, causing pollution. After the servo motor 10 is started, the output end of the servo motor 10 can drive the transmission rod 11 to rotate. The rotating transmission rod 11 drives the movable sleeve 804 to rotate, so that the fixed block 806 on the movable sleeve 804 contacts and triggers the double rotating top block 805 on the fixed ring plate 803. The transmission rod 11 rotates counterclockwise, thus driving the rotating rod 8 to rotate and retracting the wire 3 on the rotating rod 8. However, when the transmission rod 11 rotates clockwise, it cannot drive the rotating rod 8 to rotate, and similarly, the rotation of the rotating rod 8 cannot affect the transmission rod 11. However, the double rotating top block 805 drives the movable sleeve 804 to slide on the transmission rod 11 through the fixed locking block 806. The movable sleeve 804 slides on the limiting sliding shaft 809 through the limiting sliding groove 808, so that the movable sleeve 804 passes through the limiting sliding groove 808. The groove 808 is affected by the limiting slide shaft 809, and its own rotation is not affected while sliding on the transmission rod 11. As the movable sleeve 804 rotates, it will compress the positioning spring 807. Thus, the fixed block 806 can be used to push the fixed block 806 on the movable sleeve 804 to always be in close contact with the double rotating top block 805. The rotating rod 8 rotates on the limiting ring 802 through the rotating limiting groove 801. The rotating rod 8 is affected by the limiting ring 802 through the rotating limiting groove 801 and remains stable during rotation.

[0024] Reference Figure 1-4 Furthermore, the rotating rod 8 also has a rotation limiting groove 801 at one end near the wire winding box 7. A limiting ring 802 is rotatably installed in the rotation limiting groove 801. The limiting ring 802 is fixedly installed on the inner wall of the wire winding box 7. The rotating rod 8 rotates on the limiting ring 802 through the rotation limiting groove 801. The rotating rod 8 remains stable during rotation due to the influence of the limiting ring 802 through the rotation limiting groove 801.

[0025] Reference Figure 1-4Furthermore, a fixed ring plate 803 is fixedly installed on the rotating rod 8, and a movable sleeve 804 is slidably installed on the transmission rod 11. Two fixed locking blocks 806 and two double-rotating top blocks 805 are fixedly installed at the ends of the movable sleeve 804 and the fixed ring plate 803 that are close to each other. The two double-rotating top blocks 805 are in contact with the two fixed locking blocks 806 respectively. A positioning spring 807 is movably sleeved on the transmission rod 11. One end of the positioning spring 807 is in contact with the movable sleeve 804, and the other end of the positioning spring 807 is in contact with the inner wall of the wire winding box 7. Block 805 drives the movable sleeve 804 to slide on the transmission rod 11 via the fixed locking block 806. The movable sleeve 804 slides on the limiting sliding shaft 809 via the limiting sliding groove 808, so that the movable sleeve 804 is affected by the limiting sliding shaft 809 through the limiting sliding groove 808. While sliding on the transmission rod 11, it will not affect its own rotation. Since the movable sleeve 804 will compress the positioning spring 807 while rotating, the fixed locking block 806 can be used to push the fixed locking block 806 on the movable sleeve 804 to always be in close contact with the double rotating top block 805.

[0026] Reference Figure 1-4 Furthermore, two limiting grooves 808 are provided on the inner wall of the movable sleeve 804. Limiting shafts 809 are slidably installed in both limiting grooves 808. Both limiting shafts 809 are fixedly installed on the outside of the transmission rod 11. The movable sleeve 804 is affected by the limiting shafts 809 through the limiting grooves 808, and its own rotation is not affected while sliding on the transmission rod 11.

[0027] Reference Figure 1-6 Furthermore, the fixed mounting base 5 has two mounting slots 501, and movable rods 502 are slidably installed in both mounting slots 501. Both movable rods 502 are fixedly installed on the bottom side of the movable disinfection sleeve 6. Pressure blocks 503 are fixedly installed on the bottom side of both mounting slots 501. The two pressure blocks 503 are in contact with the two movable rods 502 respectively. Due to the change in the overall weight of the movable disinfection sleeve 6, the movable rods 502 will slide in the mounting slots 501, thereby triggering the pressure blocks 503, which in turn stimulates the servo motor 10 to start.

[0028] Reference Figure 1-7Furthermore, the inner wall of the active disinfection sleeve 6 has two mounting holes 601, and mounting sliders 602 are slidably installed in both mounting holes 601. Arc-shaped fixing plates 606 are fixedly installed at the ends of the two mounting sliders 602 that are close to each other. Both arc-shaped fixing plates 606 are in contact with the surface of the laser treatment pen 4. A driven rod 607 is rotatably installed on both arc-shaped fixing plates 606. A drive rod 608 is rotatably installed on the side of the two driven rods 607 that are close to each other. The two mounting sliders 602 are driven to move by the fixed spring 605, thereby bringing the two arc-shaped fixing plates 606 closer to each other, so as to fix the laser treatment pen 4 between the two arc-shaped fixing plates 606.

[0029] Reference Figure 1-7 Furthermore, a limiting groove 603 is provided on the mounting slider 602, and a limiting rod 604 is slidably installed in the limiting groove 603. The limiting rod 604 is fixedly installed on the inner wall of the mounting hole 601, and a fixing spring 605 is movably sleeved on the limiting rod 604. One end of the fixing spring 605 is fixedly installed on the inner wall of the mounting hole 601, and the other end of the fixing spring 605 is fixedly installed on the mounting slider 602. Since the mounting slider 602 will compress the fixing spring 605 while sliding, after the drive rod 608 is released, the fixing spring 605 can be used to drive the two mounting sliders 602 to move, thereby realizing that the two arc-shaped fixing plates 606 are close to each other, achieving the purpose of fixing the laser treatment pen 4 between the two arc-shaped fixing plates 606.

[0030] Reference Figure 1-5 Furthermore, two fixing plates 504 are fixedly installed on both sides of the fixed mounting base 5. Each of the four fixing plates 504 is threaded with a positioning bolt 505. The four positioning bolts 505 are respectively threaded on the top side of the laser therapy instrument body 1. The fixed mounting base 5 is installed on the laser therapy instrument body 1 using the positioning bolts 505 and the fixing plates 504.

[0031] Reference Figure 1-7 Furthermore, each end of the driven rod 607 has a driven hole 609, and a driven shaft 610 is rotatably installed in each of the two driven holes 609. The two driven shafts 610 are respectively fixedly installed on the arc-shaped fixed clamp 606 and the drive rod 608. The position of the movable drive rod 608 is such that the drive rod 608 drives the two driven rods 607 to move by the mutual cooperation of the driven holes 609 and the driven shafts 610 on both sides. The two moving driven rods 607 drive the two arc-shaped fixed clamps 606 to move away from each other by another pair of driven holes 609 and driven shafts 610.

[0032] Working principle of this invention: After using the device, the laser treatment pen 4 should first be placed inside the movable sterilization sleeve 6, and the position of the movable drive rod 608 should be adjusted. The drive rod 608 will then use the interaction of the driven holes 609 and driven shaft 610 on both sides to drive the two driven rods 607 to move. The two moving driven rods 607 will then use another pair of driven holes 609 and driven shaft 610 to drive the two arc-shaped fixing plates 606 away from each other. At this time, one end of the laser treatment pen 4 can be placed between the two arc-shaped fixing plates 606. As the arc-shaped fixing plates 606 move, the fixed mounting slider 602 will slide within the mounting hole 601, allowing the mounting... The mounting slider 602 slides on the limiting rod 604 using the limiting groove 603. As the mounting slider 602 slides, it compresses the fixing spring 605. After the drive rod 608 is released, the fixing spring 605 can drive the two mounting sliders 602 to move, thereby bringing the two arc-shaped fixing plates 606 closer together and fixing the laser treatment pen 4 between the two arc-shaped fixing plates 606. At this time, due to the change in the overall weight of the movable disinfection sleeve 6, the movable rod 502 will slide in the mounting groove 501, thereby triggering the pressure block 503, which in turn activates the servo motor 10. Because the connecting wire 3 on the laser treatment pen 4 is quite long, it is prone to being stepped on or pulled during use, and may even be pulled and dropped to the ground, causing pollution. After the servo motor 10 is started, its output can drive the transmission rod 11 to rotate. The rotating transmission rod 11 drives the movable sleeve 804 to rotate, causing the fixing block 806 on the movable sleeve 804 to contact the double rotating top block 805 on the fixing ring plate 803 and trigger rotation. Thus, when the transmission rod 11 rotates counterclockwise, it can drive the rotating rod 8 to rotate, retrieving the wire 3 on the rotating rod 8. When the transmission rod 11 rotates clockwise, it cannot drive the rotating rod 8 to rotate, and similarly, the rotation of the rotating rod 8 cannot affect the transmission rod 11. However, the double rotating top block 805 drives the movable sleeve 804 to slide on the transmission rod 11 through the fixed locking block 806. The movable sleeve 804 slides on the limiting sliding shaft 809 through the limiting sliding groove 808, so that the movable sleeve 804 is affected by the limiting sliding shaft 809 through the limiting sliding groove 808. While sliding on the transmission rod 11, it will not affect its own rotation. Since the movable sleeve 804 will compress the positioning spring 807 while rotating, the fixed locking block 806 can be used to push the fixed locking block 806 on the movable sleeve 804 to always be close to the double rotating top block 805. The rotating rod 8 rotates on the limiting ring 802 through the rotating limiting groove 801. The rotating rod 8 is affected by the limiting ring 802 through the rotating limiting groove 801 and remains stable during rotation.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
