Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, specifically a pediatric oral retractor. Background Technology

[0002] An oral retractor is a medical device typically used to open the mouth to allow doctors or nurses to perform oral examinations, surgeries, nursing care, or other treatments. It uses a mechanical structure to adjust the opening angle of the mouth, ensuring sufficient operating space.

[0003] The oral retractor used in this technology is similar in structure to a pair of scissors. It requires the doctor to apply pressure to one end so that the other end will lift up and open the child's mouth. However, if medical staff use the retractor for a long time during examinations and treatments, the burden on their hands will be extremely heavy, which may cause pain or soreness in the doctor's hands. This will undoubtedly affect the doctor's subsequent operations. At the same time, children are not as cooperative as doctors due to their nature. They may bite the retractor during the examination, which will increase the burden on the doctor's hands. In addition, the retractor is generally made of a relatively hard material. After children bite the retractor repeatedly, their gums will also suffer varying degrees of damage. Utility Model Content

[0004] To address the problems mentioned in the background section, this invention provides a pediatric oral retractor that reduces the burden on doctors' hands.

[0005] This invention solves the problem of hand soreness caused by doctors having to support the retractor for a long time during examinations of children, reducing the workload of medical staff and improving work efficiency. At the same time, the device makes the biting part of the retractor into an elastic structure, thereby alleviating damage to the gums when children bite for a long time and increasing the children's experience.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A pediatric oral retractor includes a frame with fixed blocks on both sides. A knob is rotatably mounted on the outer side of each fixed block. A connecting shaft is fixedly mounted inside the knob and passes through the frame and the fixed blocks. A main gear is fixedly mounted at the other end of the connecting shaft. A driven gear is meshed on the outer side of the main gear. A threaded rod is fixedly mounted on the outer side of the driven gear. A first retractor arm is movably mounted on the outer side of the threaded rod. An occlusal plate is movably mounted inside the other side of the first retractor arm.

[0008] Preferably, a second spreading arm is movably provided on the lower outer side of the threaded rod, and another engagement plate is movably provided inside the second spreading arm.

[0009] Preferably, the first spreading arm includes a gear head, and the gear head is meshing with a threaded rod. A connecting block is fixedly provided on the outer side of the gear head, and an mounting sleeve is fixedly provided on the other side of the connecting block. The engagement plate moves inside the mounting sleeve.

[0010] Preferably, a plurality of fixing seats are fixedly provided on the inner side of the fixing frame, and the fixing seats are rotatably connected to the threaded rod.

[0011] Preferably, the fixing frame is internally fixed with a plurality of fixing pins, and the fixing pins are rotatably connected to the first spreading arm and the second spreading arm.

[0012] Preferably, the mounting sleeve has a sliding groove inside, a limiting block is movably arranged inside the sliding groove, a reinforcing plate is fixedly arranged on the outside of the limiting block, and the reinforcing plate is fixedly connected to the interlocking plate.

[0013] Preferably, a fixed shaft is fixedly provided inside the mounting sleeve, a spring is sleeved on the outside of the fixed shaft, an elastic plate is attached to the outside of the spring, the bottom surface of the elastic plate is fixedly connected to the mounting sleeve, the top surface is attached to the reinforcing plate, and the fixed shaft passes through the elastic plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] First, this utility model utilizes a rotating knob on the outside of the fixing block. The knob drives the connecting shaft, which in turn drives the main gear. The main gear drives the driven gear, which in turn drives the threaded rod. The threaded rod engages with the gear head inside the first spreading arm, causing the connecting block and the mounting sleeve to move upward. Simultaneously, the mounting sleeve drives the biting plate to open the child's mouth. When the knob is released, the biting plate will not spring back due to the biting force of the child's mouth. This solves the problem of hand fatigue for doctors who need to continuously support the spreader during prolonged examinations of children, reducing the workload of medical staff and improving work efficiency.

[0016] Secondly, this invention provides a soft rubber pad on the top surface of the bite plate, so that when the child bites the bite plate, the bite plate will move along the fixed axis, while squeezing the elastic plate and spring, thereby reducing damage to the child's gums. It also informs the doctor of the child's current condition and increases the child's experience. Attached Figure Description

[0025] 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.

[0026] like Figures 1 to 5 As shown, this utility model provides a pediatric oral retractor, including a fixed frame 1. Fixed blocks 2 are fixedly mounted on both sides of the fixed frame 1. A knob 3 is rotatably mounted on the outer side of each fixed block 2. A connecting shaft 4 is fixedly mounted inside the knob 3, and the connecting shaft 4 passes through the fixed frame 1 and the fixed blocks 2. A main gear 5 is fixedly mounted at the other end of the connecting shaft 4. A driven gear 6 is meshed with the outer side of the main gear 5. A threaded rod 7 is fixedly mounted on the outer side of the driven gear 6. A first retractor arm 8 is movably mounted on the outer side of the threaded rod 7. The other side of the first retractor arm 8 is movably mounted inside... With a biting plate 10, by rotating the knob 3 on the outside of the fixing block 2, the knob 3 drives the connecting shaft 4, the connecting shaft 4 drives the main gear 5, the main gear 5 drives the driven gear 6, the driven gear 6 drives the threaded rod 7, and the threaded rod 7 drives the biting plate 10 inside the first opening arm 8 to open the child's mouth. At this time, when the knob 3 is released, the biting plate 10 will not rebound due to the biting force of the child's mouth. This solves the problem of hand soreness caused by doctors having to support the opening device for a long time when examining children, reduces the workload of medical staff, and improves work efficiency.

[0027] Specifically, a second opening arm 9 is movably provided on the lower outer side of the threaded rod 7, and another biting plate 10 is movably provided inside the second opening arm 9. The second opening arm 9 is used to open the child's jaw.

[0028] Furthermore, the first opening arm 8 includes a gear head 801, which is meshed with the threaded rod 7. A connecting block 802 is fixedly provided on the outer side of the gear head 801, and an installation sleeve 803 is fixedly provided on the other side of the connecting block 802. The biting plate 10 moves inside the installation sleeve 803. Through the meshing of the gear head 801 and the threaded rod 7, the biting plate 10 is driven to move and open up the cavity of the child.

[0029] Furthermore, multiple fixing seats 11 are fixedly installed on the inner side of the fixing frame 1, and the fixing seats 11 are rotatably connected to the threaded rod 7. The fixing seats 11 are mainly used to support the threaded rod 7 and fix its position.

[0030] It is worth noting that the fixed frame 1 is internally fixed with multiple fixing pins 18, and the fixing pins 18 are rotatably connected to the first spreading arm 8 and the second spreading arm 9. The fixing pins 18 are used to support the first spreading arm 8 and the second spreading arm 9, and fix their positions.

[0031] It is worth noting that the mounting sleeve 803 has a sliding groove 17 inside, and a limiting block 16 is movably arranged inside the sliding groove 17. A reinforcing plate 12 is fixedly arranged on the outside of the limiting block 16, and the reinforcing plate 12 is fixedly connected to the interlocking plate 10. The limiting block 16 is used to increase the stability of the reinforcing plate 12 and the interlocking plate 10 when sliding.

[0032] It is worth mentioning that the mounting sleeve 803 has a fixed shaft 13 inside, and a spring 15 is sleeved on the outside of the fixed shaft 13. An elastic plate 14 is attached to the outside of the spring 15, and the bottom surface of the elastic plate 14 is fixedly connected to the mounting sleeve 803, while the top surface is attached to the reinforcing plate 12. The fixed shaft 13 passes through the elastic plate 14. When the child bites the bite plate 10, the bite plate 10 drives the reinforcing plate 12 to move along the fixed shaft 13, while squeezing the elastic plate 14 and the spring 15. This reduces damage to the child's gums and increases the child's experience. The elastic plate 14 is used to reduce the effect of the spring 15 repeatedly bouncing.

[0033] Among them, the main gear 5 and the driven gear 6 are existing technologies and will not be described in detail; at the same time, this utility model also includes a power supply, a controller, and a switch, etc., which are not the main technical points of this patent and will not be described in detail; the "front, back, left, and right" perspectives of this device are as follows: Figure 1 The direction shown in the diagram is the reference.

[0034] Working principle: When using the pediatric oral retractor, firstly, the occlusal plate 10 is placed in the child's mouth. Then, the knob 3 on the outside of the fixing block 2 is rotated. The knob 3 drives the connecting shaft 4, which in turn drives the main gear 5. The main gear 5 drives the driven gear 6, which in turn drives the threaded rod 7. The two sides of the threaded rod 7 are fixed by the fixing seat 11. The threaded rod 7 engages with the gear head 801 inside the first retractor arm 8, causing the connecting block 802 and the mounting sleeve 803 to move upward. The mounting sleeve 803 simultaneously drives the occlusal plate 10 to open the child's mouth. At this point, the knob 3 is released, and the occlusal plate 10 will not rebound due to the child's biting force. This solves the problem of hand fatigue for doctors who need to support the retractor for a long time during examinations of children. The second retractor arm 9 also engages with the threaded rod 7, thereby opening the child's lower jaw. Because children have poor self-control, they may lose patience after a period of examination. When a child begins to bite the retractor, the traditional retractor, being made of hard material, can damage the child's gums. Therefore, a soft rubber pad is provided on the top surface of the occlusal plate 10. Simultaneously, when the child bites the occlusal plate 10, the occlusal plate 10 drives the reinforcing plate 12 to move along the fixed axis 13, compressing the elastic plate 14 and spring 15, thus reducing damage to the child's gums and informing the doctor of the child's current condition. The limiting block 16 slides inside the sliding groove 17, increasing the balance of the slide. The fixing pin 18 is used to fix the first retractor arm 8 and the second retractor arm 9. This invention solves the problem of hand fatigue for doctors who need to continuously support the retractor during prolonged examinations of children, reducing the workload of medical staff and improving work efficiency. Furthermore, the device features an elastic structure at the retractor's biting point, alleviating gum damage during prolonged biting and enhancing the child's experience.
