Description

Technical Field

[0001] This invention belongs to the field of oral health technology, specifically relating to an auxiliary instrument for pediatric oral treatment. Background Technology

[0002] Pediatric dentistry is a specialized medical field requiring highly specialized skills and patience. Its core challenge lies in treating children who are in a period of rapid physical and mental development, yet whose cognitive and self-control abilities are limited. The main problems and difficulties are manifested in the following aspects: 1. Fear and anxiety: Fear of unfamiliar environments, dental instruments, sounds, and unknown pain is a common reaction, mainly manifested as crying, resistance, and non-cooperation, resulting in long-term psychological trauma.

[0003] 2. Poor tolerance: It is difficult to keep the mouth open for a long time, there is a lot of saliva, and it is extremely uncomfortable to swallow saliva when the mouth is open. In addition, the gag reflex is sensitive (easily causing nausea).

[0004] 3. Characteristics of children's oral tissues: The gum tissue is more fragile and prone to bleeding; the alveolar bone is loose, and the inflammation spreads quickly; the roots of permanent teeth are not fully developed or the apical foramen is not closed, so the treatment methods are different from those for adults.

[0005] Children's oral health issues mainly focus on interproximal caries of primary teeth (tooth decay between teeth), gingivitis, swollen and bleeding gums, and cleaning challenges during orthodontic treatment (when braces are worn, food easily gets stuck around the brackets and wires). The primary treatment for these issues is flossing to remove plaque and food debris from the gum line.

[0006] However, given the common challenges in pediatric dental treatment, it is difficult for children to cooperate fully with ordinary dental floss (including children's dental floss). Ordinary dental floss requires dentists to manually drag it back and forth, but children's oral spaces are smaller than adults', and dentists' finger movements are extremely limited. Manual cleaning with dental floss takes even longer. Therefore, pediatric dental treatment is generally difficult and time-consuming, and it also places high demands on the dentist's patience.

[0007] Besides regular dental floss, there is also an electric dental floss pick on the market, with application number 202210752016.2. Its main structure includes a first clamping arm and a second clamping arm that work together to clamp a single piece of floss. The floss is moved back and forth by the oscillation of the first and second clamping arms, thus replacing manual pulling of the floss. However, this type of electric dental floss pick is not suitable for pediatric dental treatment for the following reasons: 1. The first and second clamping arms extend into the oral cavity. Children's oral cavity has little space for movement and is very sensitive. The first and second clamping arms need a space to move. Driving the dental floss to move back and forth in the narrow oral cavity of children causes the first and second clamping arms to hit the tissue around the gums. The higher the swinging frequency, the stronger the impact sensation, making it extremely difficult to get children to actively cooperate.

[0008] 2. The first and second floss clamps use an oscillating motion to drive the floss back and forth. The oscillation method of the first and second floss clamps ignores the dynamic balance problem. The vibration generated by the oscillation is large, and the vibration of the entire electric floss pick cannot be balanced. In other words, it cannot solve the problem of the floss pick "vibrating in the hand", resulting in a poor user experience for dentists.

[0009] 3. The dental floss can be detached from the first and second clamp arms. Although the dental floss can be replaced through the first and second clamp arms, the first and second clamp arms are already inserted into the oral cavity. It can only be used after the disinfection requirements are met. It cannot be used continuously and cannot meet the daily treatment needs of the hospital.

[0010] Therefore, there is currently a lack of an electric dental flosser that requires minimal oral space, has low vibration, requires no sterilization, and is particularly suitable for pediatric dental treatment. Summary of the Invention

[0011] To address the shortcomings of existing technologies, this invention provides an auxiliary instrument for pediatric oral treatment, comprising a Y-shaped bracket, with two opposing arms at the upper part and a telescopic rod at the lower part. The two arms are detachably connected to the upper end of the telescopic rod, and the distance between the two arms is adjustable. A transverse dental floss is provided between the two arms, with both ends of the floss extending along channels inside the corresponding arms to the lower end of the telescopic rod. A handle is included, with the telescopic rod extending into the handle from its upper end, thus forming a sliding connection between the telescopic rod and the handle. A drive assembly is provided inside the handle, detachably connected to both ends of the dental floss, which drives the dental floss to reciprocate between the two arms.

[0012] A preferred embodiment of the pediatric oral treatment auxiliary instrument of the present invention is as follows: the upper end of the telescopic rod is provided with a transverse T-shaped groove, which runs through both sides of the telescopic rod; the lower end of each support arm is provided with a T-shaped sliding head, which is slidably connected to the T-shaped groove, thereby allowing the support arm to be detachably connected to the telescopic rod. Further, a transverse lead screw is provided within the T-shaped groove, with opposite thread directions at both ends of the lead screw, and the two support arms are provided with threaded holes that match the corresponding threads of the lead screw. A slot is provided at one end of the lead screw; turning the lead screw clockwise with a bolt cutter reduces the distance between the two support arms. Conversely, turning the lead screw counterclockwise increases the distance between the two support arms, making adjustment simple and allowing for adjustments tailored to different children's oral cavity sizes. In addition, through the cooperation of the lead screw and the T-shaped sliding limiting structure, the two support arms can be kept from moving relative to each other without rotating the lead screw, effectively maintaining the tension of the dental floss.

[0013] The preferred embodiment of the pediatric oral treatment auxiliary instrument of the present invention is as follows: The driving component includes two symmetrically distributed motors, each motor shaft having an eccentric disc, the eccentric disc having an eccentric shaft and a balance block; it also includes intermediate tubes rotatably connected to the eccentric shafts, the upper ends of the two intermediate tubes corresponding to the two ends of the dental floss and detachably connected, with one intermediate tube located at the left end of the corresponding eccentric disc and the other at the right end. The ends of the intermediate tubes can be quickly connected to the ends of the dental floss, making floss replacement simple and convenient. The eccentric discs of the two motors rotate synchronously forward or backward. Each time they rotate to the highest and lowest points, the dental floss located between the two clamping arms moves back and forth in a straight line, simulating the operation of manually dragging dental floss. Both eccentric discs are equipped with balance blocks, which greatly reduces the vibration amplitude generated by the high-speed rotation of the eccentric discs. Only the dental floss maintains a back-and-forth straight-line motion, resulting in low vibration and low noise in the overall device, minimizing stimulation to the oral cavity during oral treatment and making it more acceptable to children.

[0014] A preferred embodiment of the pediatric oral treatment auxiliary instrument of the present invention is as follows: the side of the handle is provided with a protrusion corresponding to the drive component, and the inner cavity of the protrusion extends along the length direction of the handle; the rear cover of the protrusion is detachable, and the inner surface of the rear cover is provided with a guide rail extending along the length direction of the handle; the drive component also includes a base, two motors are fixedly connected to the inner side of the base, and the side of the base is provided with a slider adapted to the guide rail, which is slidably connected to the guide rail, thereby causing the drive component to move along the length direction of the handle. For floss replacement, the handle and the telescopic rod are connected in a telescopic manner. The specific replacement operation is as follows: the telescopic rod retracts into the handle, the floss changes from taut to slack, making it easy to separate the floss from the intermediate tube. Then, the telescopic rod is fully extended, a new Y-shaped bracket is replaced, the new floss is connected to the intermediate tube, the telescopic rod extends and the floss becomes taut, and the replacement is complete.

[0015] A preferred embodiment of the pediatric oral treatment aid in this invention is as follows: the rear cover is equipped with a spring pin, and the base has a row of positioning holes evenly spaced along the length of the handle. The drive assembly is fixed to the handle by inserting the spring pin into any one of the positioning holes. When the telescopic rod extends to a suitable position, the spring pin is inserted into the positioning hole to maintain the current position of the telescopic rod. Retracting the telescopic rod keeps the dental floss taut. Conversely, pulling out the spring pin unlocks the telescopic rod, facilitating floss replacement.

[0016] A preferred embodiment of the pediatric oral treatment auxiliary instrument of the present invention is as follows: the handle is internally equipped with a battery and an electronic control module, the electronic control module being electrically connected to the battery and the drive component respectively; the electronic control module is equipped with an on / off switch and a speed adjustment switch, both located on the rear cover. The motor speed can be controlled via the speed adjustment switch, adjusting to a suitable speed according to the different tolerance levels of children, thereby alleviating negative emotions such as resistance and fear in children.

[0017] The beneficial effects of the pediatric oral treatment auxiliary instrument of this invention are as follows: 1. The drive component only moves the dental floss back and forth in a straight line, while the entire Y-shaped bracket and handle remain stationary. The support arm does not swing, minimizing the space occupied and avoiding impact on the gums and surrounding tissues. This reduces irritation to the oral cavity to a minimum, making it particularly suitable for dental treatment in children with small and sensitive oral spaces.

[0018] 2. The Y-shaped support and handle are detachable. The Y-shaped support is used in conjunction with dental floss, and both are disposable medical supplies. The Y-shaped support and dental floss only need to be replaced after each use. The handle does not enter the oral cavity, therefore it does not require frequent sterilization. The Y-shaped support is replaced after each use, forming a sterile-free medical device for oral use that meets the daily treatment needs of hospitals. Attached Figure Description

[0022] In view of the shortcomings of the prior art, the inventors of this invention, through long-term research and extensive practice, have proposed the technical solution of this invention. The technical solution, its implementation process, and principles will be further explained below with reference to the accompanying drawings and specific implementation examples in the embodiments of this application.

[0023] like Figure 1 As shown, this embodiment provides a pediatric oral treatment auxiliary instrument, including a Y-shaped bracket 1. The upper part of the Y-shaped bracket 1 consists of two oppositely distributed support arms 2, and the lower part of the Y-shaped bracket 1 consists of a telescopic rod 3. The two support arms 2 are detachably connected to the upper end of the telescopic rod 3, and the distance between the two support arms 2 is adjustable.

[0024] The specific connection structure between the support arm 2 and the telescopic rod 3 is as follows: like Figure 1 and Figure 2 As shown, a transverse T-shaped groove 4 is provided at the upper end of the telescopic rod 3, and the T-shaped groove 4 runs through both sides of the telescopic rod 3; the lower end of each support arm 2 is provided with a T-shaped slider 5 that matches the T-shaped groove 4. In addition, a transverse lead screw 6 is provided in the T-shaped groove 4. The threads at both ends of the lead screw 6 are opposite in direction, that is, the left half of the lead screw 6 is left-handed and the right half of the lead screw 6 is right-handed, and the two support arms 2 are provided with threaded holes that match the corresponding threads of the lead screw 6. The two types of threads of the lead screw 6 are for accurate synchronous movement, and the pitch of the two threaded sections is exactly equal. A slot is provided at one end of the lead screw 6. By turning the lead screw 6 clockwise or counterclockwise with a bolt cutter, the distance between the two support arms 2 decreases or increases accordingly, thereby adjusting the distance between the two support arms 2. Different children have different gum widths, and the distance between the two support arms 2 can be adjusted to the optimal value through this adjustment method. The Y-shaped bracket 1 occupies less actual space in the oral cavity, and the pressure on the oral tissues on both sides of the gums is slight, the foreign body sensation is reduced, and it is easier to get children to actively cooperate.

[0025] In this embodiment, a transverse dental floss 7 is provided between the two support arms 2, and both ends of the dental floss 7 extend along the channels inside the corresponding support arms 2 to the lower end of the telescopic rod 3, that is, both ends of the dental floss 7 protrude from the lower end of the telescopic rod 3. In order to drive the dental floss 7 to reciprocate linearly, this embodiment also includes a handle 18. The upper end of the handle 18 is provided with a through hole adapted to the telescopic rod 3, and the lower end of the telescopic rod 3 extends into the handle 18 from the through hole at the upper end of the handle 18, thereby forming a sliding connection between the telescopic rod 3 and the handle 18. A drive assembly is provided inside the handle 18, and the drive assembly is detachably connected to both ends of the dental floss 7. The drive assembly drives the dental floss 7 to reciprocate between the two support arms 2.

[0026] The specific structure of the driver component is as follows: like Figure 2 and Figure 3As shown, the drive assembly includes two symmetrically distributed motors 8, each with an eccentric disk 9 on its shaft. Each eccentric disk 9 is elliptical in shape, with an eccentric shaft 10 and a balance block 11 at each end of its long axis. The eccentric shaft 10 has a rotatable intermediate tube 12. The lower end of each intermediate tube 12 is rotatably connected to the eccentric shaft 10, and the upper end of each intermediate tube 12 is detachably connected to one end of the dental floss 7. This detachable connection is simple: the side wall of the intermediate tube 12 has a threading hole; the end of the dental floss 7 passes through the threading hole and is knotted. The knot cannot pass through the threading hole, making connection quick and convenient. Cutting off the knot allows the dental floss 7 to be removed from the threading hole, making disassembly equally convenient. The upper ends of the two intermediate tubes 12 are detachably connected to the two ends of the dental floss 7 in a one-to-one correspondence, with one intermediate tube 12 located at the left end of the corresponding eccentric disk 9 and the other intermediate tube 12 located at the right end of the corresponding eccentric disk 9. During the synchronous rotation of the eccentric discs 9 of the two motors 8, when the middle tube 12 of the right eccentric disc 9 rotates from its highest point to its lowest point, it pulls the dental floss 7; simultaneously, the middle tube 12 of the left eccentric disc 9 rotates from its lowest point to its highest point, pushing the dental floss 7. When the middle tube 12 of the right eccentric disc 9 rotates from its lowest point to its highest point, it pushes the dental floss 7; simultaneously, the middle tube 12 of the left eccentric disc 9 rotates from its highest point to its lowest point, dragging the dental floss 7. With each synchronous rotation of the two motors 8, the dental floss 7 completes one reciprocating linear movement. During this reciprocating movement, the dental floss 7 remains taut, but it is not unable to bend even when taut. Because the Y-shaped bracket 1 in this embodiment is made of medical-grade plastic, such as polyvinyl chloride (PVC), polypropylene (PP), or polyethylene (PE), it has passed biocompatibility tests (mainly ISO 10993 series standards), ensuring it is harmless, non-allergenic, and has no carcinogenic risk to the human body. The handle 18 is made of medical-grade stainless steel, such as 316 / 316L or 317 / 317L, which offers superior corrosion resistance and allows for repeated sterilization and reuse. The handle 18 enters the oral cavity without contacting the patient, and therefore does not require frequent sterilization during daily use; sterilization is sufficient before the first use each day. As the dental floss 7 enters the gaps between teeth, the two support arms 2 can bend the floss 7 through elastic deformation to adapt to the shape of the gaps, while maintaining effective tautness. The thickness of the balance block 11 on the eccentric disc 9 is lower than that of the eccentric shaft 10. The central tube 12 does not touch the balance block 11 during oscillation; the balance block 11 serves only as a counterweight, reducing the vibration amplitude generated by the high-speed rotation of the eccentric disc 9. This results in less vibration and noise in the overall device, minimizing irritation to the oral cavity during dental treatment and making it more acceptable to children.

[0027] like Figure 1 , Figure 3 and Figure 4As shown, due to the available internal space of the handle 18, in order to fully accommodate the two motors 8, a protrusion 13 corresponding to the drive assembly is provided on the side of the handle 18, and the inner cavity of the protrusion 13 extends along the length direction of the handle 18; the back cover 14 of the protrusion 13 is detachable, and the inner surface of the back cover 14 is provided with a guide rail 15 extending along the length direction of the handle 18. The drive assembly also includes a base 16, and the two motors 8 are fixedly connected to the inner side of the base 16. The base 16 is provided with a slider 17 adapted to the guide rail 15, and the slider 17 is slidably connected to the guide rail, thereby causing the drive assembly to move along the length direction of the handle 18.

[0028] like Figure 4 As shown, the purpose of the sliding connection between the drive assembly and the rear cover 14 via the slide rail and slider 17 is to facilitate quick replacement of the dental floss 7. The specific replacement procedure is as follows: the telescopic rod 3 retracts into the handle 18, causing the dental floss 7 to loosen from its taut state, making it easier to separate the dental floss 7 from the intermediate tube 12. Then, the telescopic rod 3 is fully extended, a new Y-shaped bracket 1 is replaced, and the new dental floss 7 is connected to the intermediate tube 12. The telescopic rod 3 extends, keeping the dental floss 7 taut, completing the replacement. Furthermore, to ensure the dental floss 7 remains taut during use, a spring pin 19 is provided in the rear cover 14. The base 16 has a row of equally spaced positioning holes 20 along the length of the handle 18. Inserting the spring pin 19 into any one of the positioning holes 20 secures the drive assembly to the handle 18. After the telescopic rod 3 extends to the appropriate position, inserting the spring pin 19 into the positioning hole 20 keeps the current position of the telescopic rod 3 unchanged. Retracting the telescopic rod 3 keeps the dental floss 7 taut. Conversely, pulling out the spring pin 19 unlocks the telescopic rod 3, facilitating the replacement of the dental floss 7. In addition, for the convenience of replacement, a window 25 is provided on the side of the handle 18, and the window 25 is provided with an openable cover 26.

[0029] The electronic control component of the pediatric oral treatment auxiliary instrument in this embodiment is as follows: like Figure 3 As shown, a battery 21 and an electronic control module 22 are housed inside the handle 18. The battery 21 is a rechargeable lithium battery. Both the battery 21 and the electronic control module 22 are located at the lower end of the handle 18. The center of gravity of the entire pediatric oral treatment aid is located in the handle 18, making it easier for doctors to hold and operate, and providing a better feel. The electronic control module 22 is electrically connected to the battery 21 and the two motors 8 of the drive assembly. The electronic control module 22 has an on / off switch 23 and a speed adjustment button 24, both of which are located on the rear cover 14. The speed of the motors 8 can be controlled via the speed adjustment button 24, adjusting to a suitable speed according to the different tolerance levels of children, alleviating negative emotions such as resistance and fear in children. The entire electronic control part is very simple, without complex circuitry, and is simple and durable.

[0030] The specific usage method of the pediatric oral treatment auxiliary instrument in this embodiment is as follows: S1. For first use, disinfect the handle 18.

[0031] S2. Take out the new Y-shaped bracket 1 from the sterile bag. The Y-shaped bracket 1 comes with dental floss 7.

[0032] S3. Adjust the distance between the two aprons 2 according to the patient's gingival width to avoid the apron spacing being too wide.

[0033] S4. Insert the telescopic rod 3 of the Y-shaped bracket 1 into the handle 18, remove the cover plate 26 of the handle 18, insert the two ends of the dental floss 7 into the threading holes of the two intermediate tubes 12 one by one, and tie a knot at the end of the dental floss 7.

[0034] S5. After extending the telescopic rod 3 to the appropriate position, insert the spring pin 19 into the positioning hole 20 and tighten the dental floss 7.

[0035] S6. Press the power button 23 to turn on the machine, and turn the speed control button 24 to adjust the reciprocating speed of the dental floss 7 to a level that is acceptable to the patient.

[0036] S7. After use, pull out the spring pin 19, remove the cover plate 26, cut off the two knots, fully pull out the telescopic rod 3, and repeat S2-S6. The next patient can continue to use it.

[0037] As can be seen from the above usage method, only the handle 18 needs to be disinfected for the first time during daily use, and only the Y-shaped bracket 1 needs to be replaced afterward, thus achieving disinfection-free operation.

[0038] It should be understood that the above embodiments are only for illustrating the technical concept and features of the present invention, and are intended to enable those skilled in the art to understand the content of the present invention and implement it accordingly. It should not be considered that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present invention.
