Description
Technical Field
[0001] This utility model relates to the field of dental technology, and in particular to a safe and easy-to-operate dental fissure sealing device. Background Technology
[0002] Pit and fissure sealant refers to the application of a sealant material to the pits and fissures on the occlusal and buccal / lingual surfaces of the tooth crown without damaging the tooth structure. As the sealant flows into and penetrates the pits and fissures, it hardens and forms a protective barrier that covers the pits and fissures. This prevents cariogenic bacteria and acidic metabolic products from eroding the tooth structure, thus preventing pit and fissure caries.
[0003] Traditionally, when performing fissure sealant treatment on children, the dental handpiece is first used to clean the fissures of the teeth. The dentist holds the handpiece, applies cleaning agent to the brush head, and then rotates the handpiece to clean the fissures. After that, the sealant is applied to the fissures. However, in practice, it has been found that to ensure the effectiveness of the sealant, the dentist needs to work slowly and carefully through the fissures. Holding the handpiece for a long time can cause the fingers to stiffen, leading to the handpiece shaking and potentially touching the inside of the mouth, causing injury and posing a safety hazard. Utility Model Content
[0004] The technical problem this invention aims to solve is that, in order to ensure the effectiveness of fissure sealing, doctors need to slowly and carefully treat the fissures during cleaning. However, holding a mobile phone for a long time can cause the fingers to stiffen, leading to the phone shaking and touching the inside of the mouth, causing injury and posing a certain safety hazard.
[0005] The technical solution adopted by this utility model to solve its technical problem is: a safe and easy-to-operate dental fissure sealing device, including a straight handpiece, a stabilizing device and a fixing device. One end of the straight handpiece is fixedly connected to a head, and a brush head is provided on the end face of the head. The stabilizing device is installed on the arc surface of the straight handpiece by means of the fixing device, and the stabilizing device keeps the hand holding the straight handpiece handle in a stable and limited position.
[0006] The effect achieved by the above components is as follows: When sealing the pits and fissures of a child's teeth, the doctor first holds a straight handpiece and uses a stabilizing device to fix the fingers holding the handle. Then, the cleaning agent is applied to the brush head, and the handpiece head is rotated so that the brush head is attached to the pit and fissure of the teeth to clean the pits and fissures.
[0007] Preferably, the stabilizing device includes a fixing ring, which is sleeved on the arc surface of the straight handpiece.

[0010] The effect achieved by the above components is that, through the setting of the anti-slip pad, when the inner wall of the retaining ring is pressed against the surface of the finger, it can form a protective layer on the surface of the finger, making it less likely to cause blood blockage and poor circulation due to excessive pressure.
[0011] Preferably, an operating block is fixedly connected to the arc surface of the retaining ring, and the surface of the operating block is provided with a plurality of anti-slip protrusions.
[0012] The effect achieved by the above components is that, by setting the operating block, after cleaning the pits and fissures, the rotation of the retaining ring is made more convenient by snapping the operating block, thus further improving the ease of operation of the hand dryer.
[0013] Preferably, torsion springs are respectively fitted on the arc surfaces at both ends of the rotating shaft, and the two ends of the torsion springs are fixedly connected to the surfaces of the rotating shaft and the mounting block, respectively.
[0014] The effect achieved by the above components is as follows: by setting the torsion spring, after the doctor's finger is attached to the fixing ring, the retaining ring will quickly cover the surface of the finger under the torsional force of the torsion spring, thus facilitating the engagement of the retaining block and the retaining slot.
[0015] Preferably, the fixing device includes a fixing plate, which is fixedly connected to the arc surface of the fixing ring. A screw is fixedly connected to the arc surface of the straight handpiece, and the screw is engaged with the inner wall of the fixing plate.

[0017] Preferably, a washer is fitted on the arc surface of the screw, and the washer is a gasket.
[0018] The effect achieved by the above components is that, through the setting of the washer, the nut is more stably and closely fitted when it contacts and presses against the surface of the fixed plate, and gaps are less likely to occur, thus making the position of the nut more stable.
[0019] Preferably, a connecting rope is fixedly connected to the surface of the nut, and the other end of the connecting rope is fixedly connected to the arc surface of the screw.
[0020] The effect achieved by the above components is that the connecting rope makes the nut easier to pick up during use, thereby allowing for faster fixation of the retaining ring and preventing the nut from being lost during use.

[0031] Figure 1 The invention relates to a safe and easy-to-operate dental fissure sealant device, which includes a straight handpiece 1, a stabilizing device 4, and a fixing device 5. One end of the straight handpiece 1 is fixedly connected to a head 2, and a brush head 3 is provided on the end face of the head 2. The stabilizing device 4 is mounted on the arc surface of the straight handpiece 1 by means of the fixing device 5, and the stabilizing device 4 keeps the hand holding the handle of the straight handpiece 1 in a stable and limited position.
[0032] Figure 1 , Figure 2 and Figure 3The stabilizing device 4 shown includes a fixing ring 41, which is fitted onto the arc surface of the handpiece 1. A reinforcing ring 48, which is a rubber ring, is fixedly connected to the inner wall of the fixing ring 41. Two mounting blocks 42 are fixedly connected to the arc surface of the fixing ring 41. The two mounting blocks 42 are rotatably connected to a rotating shaft 43. A retaining ring 45 is rotatably connected to the arc surface of the rotating shaft 43. A retaining groove 46 is provided on one side of the inner wall of the retaining ring 45. A retaining block 47 is engaged with the inner wall of the retaining groove 46. The retaining block 47 is fixedly connected to the arc surface of the fixing ring 41. A groove block 410 is connected to the arc surface of the fixing ring 41. When sealing the pits and fissures of a child's teeth, the doctor first holds the handpiece 1, then places the pad of his thumb against the inner wall of the groove block 410, and then rotates the fixing ring 410. The fixed ring 41 rotates on the pivot 43 on the mounting block 42, causing the inner wall of the retaining ring 45 to press against the surface of the index finger and engage with the surface of the retaining block 47 fixedly connected to the surface of the fixed ring 41, thus fixing the position of the fixed ring 41. Then, the cleaning agent is adhered to the brush head 3, and the head 2 of the handpiece 1 is rotated, causing the brush head 3 to adhere to the tooth fissure and clean the fissure. At this time, during tooth fissure sealant treatment, the stability between the operator's hand and the handpiece 1 can be better guaranteed, and the finger is less likely to loosen, causing the handpiece 1 to shake and cause collision damage to the inside of the mouth. It also makes it more convenient and longer for the doctor to operate, and allows for more precise fine-tuning, improving the use effect and practicality of the handpiece 1.
[0033] Figure 1 , Figure 2 and Figure 3 The inner wall of the retaining ring 45 shown is fixedly connected to an anti-slip pad 49, which is a sponge pad. The anti-slip pad 49 can form a protective layer on the finger surface when the inner wall of the retaining ring 45 is pressed against the finger surface, preventing blood circulation from being blocked due to excessive pressure. An operating block 411 is fixedly connected to the arc surface of the retaining ring 45. The surface of the operating block 411 is provided with several anti-slip protrusions. After cleaning the pit and fissure, the retaining ring 45 can be rotated more easily by pressing the operating block 411, which further improves the ease of operation of the handpiece 1. Torsion springs 44 are respectively sleeved on the arc surfaces of the two ends of the rotating shaft 43. The two ends of the torsion springs 44 are fixedly connected to the surfaces of the rotating shaft 43 and the mounting block 42, respectively. With the torsion springs 44, after the doctor's finger is placed on the fixing ring 41, the retaining ring 45 will quickly cover the finger surface under the torsional force of the torsion springs 44, which facilitates the engagement of the retaining block 47 and the retaining groove 46.
[0034] Figure 1 and Figure 4The fixing device 5 shown includes a fixing plate 51, which is fixedly connected to the arc surface of the fixing ring 41. A screw 52 is fixedly connected to the arc surface of the handpiece 1, and the screw 52 is engaged with the inner wall of the fixing plate 51. A nut 53 is threadedly connected to the arc surface of the screw 52, and the nut 53 abuts against the surface of the fixing plate 51. When the fixing ring 41 of the stabilizing device 4 is put on the handle of the handpiece 1, the inner wall of the fixing plate 51 fixedly connected to the fixing ring 41 will engage with the screw 52 of the handpiece 1. Then the nut 53 is threadedly connected to the screw 52 until the nut 53 contacts and presses against the surface of the fixing plate 51. At this time, the stabilizing device 4 is more stable and firm in use, and it is not easy to slip or deviate abnormally, thus ensuring the stable positioning of the doctor's hand.
[0035] Figure 1 and Figure 4 A washer 55 is fitted onto the arc surface of the screw 52 shown. The washer 55 is a washer 55. The washer 55 makes the nut 53 more stable and fits better when it contacts and presses against the surface of the fixing plate 51, and it is less likely to have gaps. This makes the position of the nut 53 more stable. A connecting rope 54 is fixedly connected to the surface of the nut 53. The other end of the connecting rope 54 is fixedly connected to the arc surface of the screw 52. The connecting rope 54 makes the nut 53 easier to pick up during use, thereby fixing the position of the fixing ring 41 more quickly, and also makes the nut 53 less likely to be lost during use.
[0036] Working principle: When sealing the dental fissures of children, the dentist first holds the handpiece 1 and places the pad of their thumb against the inner wall of the groove block 410. Then, the fixing ring 41 is rotated, causing the pivot 43 on the mounting block 42 to rotate, pressing the inner wall of the retaining ring 45 against the surface of the index finger. The inner wall of the retaining ring 45 is then engaged with the surface of the retaining ring 41, which is fixedly connected to the surface of the retaining block 47, thus fixing the position of the fixing ring 41. Then, the cleaning agent is applied to the brush head 3, and the handpiece 1 is rotated, allowing the brush head 3 to adhere to the dental fissures for cleaning. This method better ensures the stability between the operator's hand and the handpiece 1 during dental fissure sealing treatment, preventing the fingers from loosening and causing the handpiece 1 to shake and collide with the oral cavity. It also makes the operation more convenient and longer for the dentist, allowing for more precise fine-tuning and improving the effectiveness and practicality of the handpiece 1.
[0037] When the fixing ring 41 of the stabilizing device 4 is put on the handle of the straight hand machine 1, the inner wall of the fixing plate 51 fixedly connected to the fixing ring 41 will be engaged with the screw 52 of the straight hand machine 1. Then, the nut 53 fixedly connected to the connecting rope 54 is threaded onto the screw 52 until the nut 53 contacts and presses against the surface of the fixing plate 51. At this time, the stabilizing device 4 is more stable and firm in use, and it is not easy to slip or deviate abnormally, thus ensuring the stable positioning of the doctor's hand.
[0038] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
