Description

Technical Field

[0001] This invention relates to the field of medical devices, and more particularly to an auxiliary grinding device for periodontal scaling. Background Technology

[0002] The main causes of periodontitis are tartar and plaque that adhere to the surface of the tooth roots. We generally remove deep-seated tartar and plaque through subgingival scaling, commonly known as deep cleaning. Scalpels are commonly used tools in periodontal treatment. If the instruments are dull, they will not remove tartar completely and may damage soft tissue. Therefore, using sharp periodontal scalers in clinical practice can improve the sensitivity of fine tactile sensation, thereby effectively removing tartar, reducing operator fatigue, saving time, and minimizing patient discomfort. To achieve the best results in periodontal treatment, periodontal scalers should be slightly sharpened after each use to maintain their sharpness.

[0003] Currently, most staff members use a whetstone to sharpen the tips of periodontal scalers after use. However, because different periodontal scaler tips have different shapes and are generally quite thin, the technique for sharpening them is very precise. However, when sharpening the tips, staff members cannot always maintain a stable hand to control the pressure and angle of the sharpening. Even a slight hand tremor during sharpening will affect the results, leading to insufficient smoothness and sharpness of the scaler tip, potentially causing damage. Furthermore, manual sharpening is inefficient. Summary of the Invention

[0004] In view of this, the present invention provides an auxiliary sharpening device for periodontal scaling instruments, which can sharpen periodontal scaling instruments more quickly and stably, making the periodontal scaling instruments smoother and sharper, and improving the sharpening effect.

[0005] The technical solution is: an auxiliary grinding device for periodontal scaling, comprising a base plate, a protective shell, slide rails, a positioning mechanism, a grinding mechanism, and a one-way grinding mechanism. The protective shell is fixedly connected to the side of the base plate, and two slide rails are fixedly connected to the side of the base plate. The two slide rails are symmetrically arranged and both slide rails are located inside the protective shell. The positioning mechanism is located on the base plate, the grinding mechanism is located on the positioning mechanism, and the one-way grinding mechanism is located on the positioning mechanism.

[0006] Furthermore, the positioning mechanism includes a gear disk, a lower locking sleeve, an L-shaped limiting rod, an upper locking sleeve, a slotted belt, a screw, a first rotating handle, a sliding support frame, a lead screw, and a second rotating handle. The gear disk is rotatably connected to the side of the base plate and is located inside the protective shell. The lower locking sleeve is fixedly connected to the top of the gear disk and has a limiting block. The L-shaped limiting rod is fixedly connected to one side of the lower locking sleeve. The upper locking sleeve is rotatably connected to the lower locking sleeve, and the slotted belt is fixedly connected to the upper locking sleeve near the limiting block of the lower locking sleeve. Furthermore, the slotted belt is engaged with the locking sleeve's limiting block, the screw is rotatably connected to the side of the base plate, the screw passes through the protective shell, the screw meshes with the gear disc, the first rotating handle is fixedly connected to the end of the screw located outside the protective shell, a sliding support frame is slidably connected between the two slide rails, the sliding support frame is located inside the protective shell, the lead screw is threadedly connected to the lower part of the sliding support frame, the lead screw passes through the protective shell, the lead screw is rotatably connected to the base plate, and the second rotating handle is fixedly connected to the end of the lead screw located outside the protective shell.

[0007] Furthermore, the inner sides of both the upper and lower locking sleeves are provided with several friction strips.

[0008] Furthermore, the polishing mechanism includes a motor, a rotating disk, a small round rod, a slotted cross bracket, a polishing stone, and a return spring. The motor is fixedly connected to the upper part of the sliding support frame, the rotating disk is fixedly connected to the output shaft of the motor, the small round rod is fixedly connected to the side of the rotating disk away from the motor, the slotted cross bracket is slidably connected to the sliding support frame, the slotted cross bracket has a groove, the small round rod is slidably connected to the groove of the slotted cross bracket, the polishing stone is slidably connected to the slotted cross bracket, and two return springs are connected between the slotted cross bracket and the polishing stone.

[0009] Furthermore, the unidirectional grinding mechanism includes a slanted guide plate, a slanted baffle, a U-shaped support rod, and a slotted top rod. The slanted guide plate is fixedly connected to the upper part of the sliding support frame. A guide groove is formed on the slanted guide plate. Two slanted baffles are fixedly connected to the slanted guide plate, and the two slanted baffles are staggered. The U-shaped support rod is fixedly connected to the bottom of the grinding stone plate. The slotted top rod is slidably connected to the U-shaped support rod and slidably connected to the grinding stone plate. The slotted top rod is also slidably connected to the guide groove of the slanted guide plate.

[0010] Furthermore, it also includes a grinding stone cleaning mechanism, which is mounted on the base plate. The grinding stone cleaning mechanism includes a support guide plate, a guide slider, a T-shaped scraper, a guide round rod, and a second return spring. The support guide plate is fixedly connected to the side of the base plate and passes through the protective shell. The guide slider is slidably connected to the upper part of the support guide plate. Two T-shaped scrapers are slidably connected to the guide slider. The two T-shaped scrapers are symmetrically arranged and both T-shaped scrapers are in contact with the grinding stone. Guide round rods are fixedly connected to each of the two T-shaped scrapers and are slidably connected to the guide slider. A second return spring is connected between the guide slider and the two T-shaped scrapers.

[0011] Furthermore, it also includes brush plates, with brush plates fixedly connected to both of the two T-shaped scrapers, and the two brush plates are arranged symmetrically.

[0012] Furthermore, it also includes a water tank, which is fixedly connected between the top of the two T-shaped scrapers on the side near the terrazzo slab, and the water tank has several drainage holes at the bottom.

[0013] The beneficial effects are:

[0014] The operator first unlocks the upper locking sleeve, places the periodontal scaling tool on the lower locking sleeve, and then relocks the upper locking sleeve. This allows the lower and upper locking sleeves to limit the periodontal scaling tool, while the L-shaped limiting rod also limits the tip of the periodontal scaling tool, ensuring stable grinding of the tip later. Then, the operator rotates handle one, causing the lower and upper locking sleeves and the periodontal scaling tool to swing together. When the periodontal scaling tool swings to the appropriate angle, the operator stops rotating handle one, and the screw locks the gear plate, keeping the tip of the periodontal scaling tool at the appropriate angle for more stable grinding of the tip later.

[0015] In addition, the operator rotates handle two to move the grinding stone plate into contact with the tip of the periodontal scaling instrument. At the same time, the lead screw locks the sliding support frame, allowing the grinding stone plate to stably grind the tip of the periodontal scaling instrument. The operator then starts the motor, which drives the grinding stone plate to move back and forth. Under the guidance of the guide plate's groove, the grinding stone plate also moves back and forth, allowing the grinding stone plate to grind the tip of the periodontal scaling instrument in one direction. Unidirectional grinding of the tip of the periodontal scaling instrument ensures that the contact opening faces only one side, thus not only quickly grinding the tip of the periodontal scaling instrument but also making the tip smoother and sharper without damaging it.

[0016] In addition, when the grinding stone moves towards the side closer to the support guide plate, it pushes the T-shaped scrapers to move. Under the elastic force of the return spring two, the two T-shaped scrapers will remain in close contact with the grinding stone. When the grinding stone grinds the tip of the periodontal scaler, some debris will be generated. When the grinding stone moves back and forth, the two T-shaped scrapers will scrape away the debris remaining on the grinding stone, preventing these debris from remaining on the grinding stone and affecting the grinding effect. This allows the grinding stone to grind the tip of the periodontal scaler more smoothly and sharply, resulting in a better grinding effect.

[0017] In addition, when the staff places the periodontal scaling instrument on the lower locking sleeve, the tip of the periodontal scaling instrument is located between the two brush plates. During the swinging process of the periodontal scaling instrument, the two brush plates clean the tip of the periodontal scaling instrument, avoiding the residue of impurities on the tip of the periodontal scaling instrument, which would affect the flatness of the tip and thus make the periodontal scaling instrument smoother and sharper. During the swinging and resetting process of the periodontal scaling instrument, the two brush plates will clean the debris remaining on the tip of the periodontal scaling instrument.

[0034] Example 1

[0035] An auxiliary grinding device for periodontal scaling, such as Figures 1-12 As shown, it includes a base plate 1, a protective shell 2, slide rails 3, a positioning mechanism, a grinding mechanism, and a one-way grinding mechanism. The protective shell 2 is bolted to the upper side of the base plate 1. Two slide rails 3 are bolted to the upper side of the base plate 1. The two slide rails 3 are symmetrically arranged and horizontally arranged. Both slide rails 3 are located inside the protective shell 2. The positioning mechanism is located on the base plate 1 and is used to position the periodontal scaling device. The grinding mechanism is located on the positioning mechanism and is used to grind the periodontal scaling device. The one-way grinding mechanism is located on the positioning mechanism.

[0036] The positioning mechanism includes a gear disk 41, a lower locking sleeve 42, an L-shaped limiting rod 421, an upper locking sleeve 43, a slotted belt 431, a screw 44, a first rotating handle 441, a sliding support frame 45, a lead screw 46, and a second rotating handle 461. The gear disk 41 is rotatably connected to the upper side of the base plate 1 and is located inside the protective shell 2. The lower locking sleeve 42 is fixedly connected to the top of the gear disk 41 and has a limiting block. The L-shaped limiting rod 421 is bolted to one side of the lower locking sleeve 42. The upper locking sleeve 43 is rotatably connected to the lower locking sleeve 42. The slotted belt 431 is bolted to the upper locking sleeve 43 near the limiting block of the lower locking sleeve 42. 431 is engaged with the locking sleeve limit block. The screw 44 is rotatably connected to the upper side of the base plate 1. The screw 44 is horizontally set and passes through the protective shell 2. The screw 44 meshes with the gear disk 41. The first rotating handle 441 is fixedly connected to the end of the screw 44 located outside the protective shell 2. A sliding support frame 45 is slidably connected between the two slide rails 3. The sliding support frame 45 is located inside the protective shell 2. The lead screw 46 is threadedly connected to the lower part of the sliding support frame 45. The lead screw 46 is horizontally set and passes through the protective shell 2. The lead screw 46 is rotatably connected to the base plate 1. The second rotating handle 461 is fixedly connected to the end of the lead screw 46 located outside the protective shell 2.

[0037] The inner sides of both the upper locking sleeve 43 and the lower locking sleeve 42 are provided with several friction strips.

[0038] The polishing mechanism includes a motor 51, a rotating disk 52, a small round rod 521, a slotted cross bracket 53, a polishing stone 54, and a return spring 55. The motor 51 is bolted to the upper part of the sliding support frame 45. The rotating disk 52 is fixedly connected to the output shaft of the motor 51. The small round rod 521 is hinged to the side of the rotating disk 52 away from the motor 51. The slotted cross bracket 53 is slidably connected to the sliding support frame 45. The slotted cross bracket 53 has a groove. The small round rod 521 is slidably connected to the groove of the slotted cross bracket 53. The polishing stone 54 is slidably connected to the slotted cross bracket 53. Two return springs 55 are connected between the slotted cross bracket 53 and the polishing stone 54 through hooks. Both return springs 55 are sleeved on the polishing stone 54.

[0039] The unidirectional grinding mechanism includes a slanted guide plate 61, a slanted baffle 62, a U-shaped support rod 63, and a slotted top rod 64. The slanted guide plate 61 is bolted to the upper part of the sliding support frame 45. A guide groove is provided on the slanted guide plate 61. Two slanted baffles 62 are fixedly connected to the slanted guide plate 61, and the two slanted baffles 62 are staggered. The U-shaped support rod 63 is bolted to the bottom of the grinding stone plate 54. The slotted top rod 64 is slidably connected to the U-shaped support rod 63. The slotted top rod 64 is slidably connected to the grinding stone plate 54, and the slotted top rod 64 is slidably connected to the guide groove of the slanted guide plate 61.

[0040] Initially, because the guide groove of the inclined guide plate 61 is pressed against the slotting top rod 64, the return spring 55 is in a stretched state. In actual operation, the operator first unties the slotting belt 431 from the limiting block of the lower locking sleeve 42, unlocks the upper locking sleeve 43, then rotates the upper locking sleeve 43 to open it. Next, the periodontal curette is placed on the lower locking sleeve 42, with the tip of the periodontal curette placed on the L-shaped limiting rod 421. The L-shaped limiting rod 421 limits the tip of the periodontal curette. Then, the upper locking sleeve 43 is put back on the lower locking sleeve 42, and the slotting belt 431 is snapped back onto the limiting block of the lower locking sleeve 42 to limit the upper locking sleeve 43. This allows the lower locking sleeve 42 and the upper locking sleeve 43 to limit the periodontal curette. To ensure stable grinding of the periodontal scaling tool tip, the operator rotates handle 441. Rotating handle 441 causes screw 44 to rotate and move, which in turn rotates gear disc 41. The gear disc 41 then causes the lower locking sleeve 42, upper locking sleeve 43, and the periodontal scaling tool to swing together. When the periodontal scaling tool reaches the appropriate angle, the operator stops rotating handle 441. Screw 44 locks gear disc 41, maintaining the periodontal scaling tool tip at the correct angle for more stable grinding. Then, the operator rotates handle 461, which drives lead screw 4... Rotating the screw 46 causes the sliding support frame 45 to move along the slide rail 3 away from the rotating handle 461. This movement of the sliding support frame 45 causes the motor 51, the inclined guide plate 61, and the slotted cross bracket 53 to move together. The movement of the slotted cross bracket 53, via the return spring 55, causes the grinding plate 54 to move. The movement of the motor 51 causes the rotating disk 52 and the small round rod 521 to move together. The movement of the inclined guide plate 61 causes the inclined baffle 62 to move. The movement of the grinding plate 54 causes the U-shaped support rod 63 and the slotted top rod 64 to move together. The grinding plate 54 then contacts the tip of the periodontal scaling instrument. The operator then stops rotating the rotating handle 461, and the screw 46 locks the sliding support frame 45, thus... The grinding stone slab 54 then stably grinds the tip of the periodontal scaling instrument. Next, the operator starts the motor 51. The output shaft of the motor 51 rotates, causing the rotating disk 52 and the small round rod 521 to rotate together. The rotation of the small round rod 521 pushes the slotted cross bracket 53 to move back and forth through the groove of the slotted cross bracket 53. This back and forth movement of the slotted cross bracket 53 causes the grinding stone slab 54 to move back and forth. When the grinding stone slab 54 moves closer to the gear disk 41, it drives the slotted push rod 64 to move along the guide groove of the inclined guide plate 61. Simultaneously, the movement of the grinding stone slab 54 grinds the tip of the periodontal scaling instrument. When the slotted push rod 64 reaches one of the inclined baffles 62, the guide groove of the guide plate no longer holds the slotted push rod 64.When the return spring 55 resets, it causes the grinding stone plate 54, U-shaped support rod 63, and slotted push rod 64 to move towards the side closer to the rotating handle 461. Simultaneously, the slotted push rod 64 moves and contacts one of the inclined baffles 62, and is pushed upwards by one of the inclined baffles 62. At this point, the grinding stone plate 54 disengages from the tip of the periodontal scaling instrument. When the grinding stone plate 54 moves away from the gear disc 41, it causes the slotted push rod 64 to continue moving towards the side closer to the rotating handle 461 along the inclined surface of one of the inclined baffles 62. The movement of the slotted push rod 64 towards the side closer to the rotating handle 461 causes the grinding stone plate 54 to move, compressing the return spring 55. When the slotted push rod 64... When the slotted push rod 64 moves to the top of the inclined surface of one of the inclined baffles 62, it will move downward under the action of gravity. One of the inclined baffles 62 will hold the slotted push rod 64 in place. As the grinding stone plate 54 continues to move away from the gear disk 41, it will drive the slotted push rod 64 to continue moving. As the slotted push rod 64 continues to move, it will disengage from one of the inclined baffles 62 and be held back by the guide groove of the guide plate. The grinding stone plate 54 will continue to move, driving the slotted push rod 64 to continue moving along the guide groove of the guide plate. When the slotted push rod 64 moves to the other inclined baffle 62, the guide groove of the guide plate will no longer hold the slotted push rod 64 in place. The reset spring 55 will reset, driving the grinding stone plate 54, the U-shaped support rod 63, and the slotted push rod 64 to move. 4. Move away from the rotating handle 461. Simultaneously, the slotted push rod 64 moves and contacts another inclined baffle 62, and is pushed upward by the other inclined baffle 62. At this time, the grinding stone plate 54 will re-contact the tip of the periodontal scaler. When the grinding stone plate 54 moves closer to the gear plate 41, the movement of the grinding stone plate 54 will drive the slotted push rod 64 to continue moving away from the rotating handle 461 along the inclined surface of the other inclined baffle 62. The movement of the slotted push rod 64 away from the rotating handle 461 will drive the grinding stone plate 54 to move, the return spring 55 is stretched, and the movement of the grinding stone plate 54 will continue to grind the tip of the periodontal scaler. When the slotted push rod 64 moves to the inclined surface of the other inclined baffle 62, the grinding stone plate 54 will continue to grind the tip of the periodontal scaler. When the surface is at its highest point, the slotted push rod 64 moves downwards under gravity. Another inclined baffle 62 then holds the slotted push rod 64 in place. As the grinding stone plate 54 continues to move, it drives the slotted push rod 64 to move further. The slotted push rod 64 then disengages from the other inclined baffle 62 and is held back by the guide groove of the guide plate. This process repeats, causing the grinding stone plate 54 to move back and forth simultaneously, unidirectionally grinding the tip of the periodontal scaler. Unidirectional grinding of the periodontal scaler tip ensures that the occlusal opening faces only one side, thus not only quickly grinding the tip but also making it smoother and sharper without damaging it.

[0041] When the tip of the periodontal scaling instrument has finished sharpening, the operator first turns off the motor 51, then rotates the handle 461 in the reverse direction. Rotating the handle 461 in the reverse direction will cause the lead screw 46 to rotate in the reverse direction, which in turn will cause the sliding support frame 45 to reset. The sliding support frame 45 will then cause the motor 51, rotating disk 52, small round rod 521, slotted cross bracket 53, and inclined guide plate 61 to reset together. The reset of the slotted cross bracket 53 will, through the reset spring 55, cause the grinding stone plate 54, U-shaped support rod 63, and slotted top rod 64 to reset together. The reset of the grinding stone plate 54 will disengage from the tip of the periodontal scaling instrument. The inclined guide plate 61... The reset will cause the inclined baffle 62 to reset. Then, the operator will rotate the handle 441 in the opposite direction. Rotating the handle 441 in the opposite direction will cause the screw 44 to rotate in the opposite direction and reset. The screw 44 will rotate in the opposite direction, causing the gear disk 41 to rotate in the opposite direction. The gear disk 41 will rotate in the opposite direction, causing the lower locking sleeve 42 and the upper locking sleeve 43 to reset together. Then, the operator will untie the slotted belt 431 from the limit block of the lower locking sleeve 42, open the upper locking sleeve 43, remove the periodontal scraper placed on the lower locking sleeve 42, put the upper locking sleeve 43 back on the lower locking sleeve 42, and put the slotted belt 431 back on the limit block of the lower locking sleeve 42.

[0042] Example 2

[0043] Based on Example 1, such as Figures 2-14 As shown, it also includes a grinding stone cleaning mechanism, which is mounted on the base plate 1. The grinding stone cleaning mechanism includes a support guide plate 71, a guide slider 72, T-shaped scrapers 73, a guide rod 74, and a return spring 75. The support guide plate 71 is bolted to the upper side of the base plate 1 and passes through the protective shell 2. The guide slider 72 is slidably connected to the upper part of the support guide plate 71. Two T-shaped scrapers 73 are slidably connected to the guide slider 72. The T-shaped scrapers 73 are symmetrically arranged, with both T-shaped scrapers 73 being horizontally positioned and in contact with the polishing stone 54. Each T-shaped scraper 73 is hinged with a guide rod 74, which is also horizontally positioned and slidably connected to a guide slider 72. A second return spring 75 is connected between the guide slider 72 and the two T-shaped scrapers 73 via a hook, and the second return spring 75 is sleeved on the guide rod 74.

[0044] Initially, when the operator places the periodontal scaling tool on the lower locking sleeve 42, the tip of the scaling tool is positioned between the two T-shaped scrapers 73. As the scaling tool swings, it moves the T-shaped scrapers 73 towards the screw 44. This movement of the T-shaped scrapers 73 causes the guide slider 72 and guide rod 74 to move together. When the grinding stone plate 54 moves towards the support guide plate 71, it pushes the T-shaped scrapers 73 and guide slider 72 together, compressing the second return spring 75. Simultaneously, under the elastic force of the second return spring 75, the two T-shaped scrapers 73 remain in close contact with the grinding stone plate 54. When the grinding stone plate 54 moves left and right... When the periodontal scaling tool tip is moved back and forth, some debris is generated. As the stone plate 54 moves back and forth, the two T-shaped scrapers 73 scrape away the debris remaining on the stone plate 54, preventing it from affecting the polishing effect. This allows the stone plate 54 to polish the tip of the periodontal scaling tool more smoothly and sharply, resulting in a better polishing effect. When the stone plate 54 returns to its original position, it no longer presses the T-shaped scrapers 73. The return spring 2 75 returns to its original position, which drives the T-shaped scrapers 73 and the guide slider 72 to return to their original positions together. When the periodontal scaling tool swings to return to its original position, it drives the T-shaped scrapers 73, the guide slider 72, and the guide rod 74 to return to their original positions together.

[0045] Example 3

[0046] Based on Example 2, such as Figure 14 As shown, it also includes a brush plate 8. The two T-shaped scraper rods 73 are each connected to the brush plate 8 by bolts. The two brush plates 8 are arranged symmetrically and are made of soft material.

[0047] Initially, when the staff places the periodontal scaling instrument on the lower locking sleeve 42, the tip of the periodontal scaling instrument is positioned between the two brush plates 8. When the periodontal scaling instrument swings, it moves the brush plates 8 and the T-shaped scraper 73. At the same time, during the swinging process, the two brush plates 8 clean the tip of the periodontal scaling instrument, preventing any impurities from remaining on the tip and affecting the smoothness of the tip's wear, thus making the periodontal scaling instrument smoother and sharper. During the swinging and resetting process of the periodontal scaling instrument, the two brush plates 8 clean up any debris remaining on the tip of the periodontal scaling instrument.

[0048] Example 4

[0049] Based on Example 3, such as Figure 13 As shown, it also includes a water tank 9. The top of the two T-shaped scrapers 73 near the terrazzo slab 54 is connected to the water tank 9 by bolts. The lower part of the water tank 9 has several drainage holes.

[0050] Initially, when the grinding stone 54 comes into contact with the tip of the periodontal scaling instrument, the staff adds clean water to the water tank 9 and then starts the motor 51. The clean water in the water tank 9 flows through several drainage holes to the two T-shaped scrapers 73 to clean the T-shaped scrapers 73. This reduces the friction between the T-shaped scrapers 73 and the grinding stone 54 and allows the T-shaped scrapers 73 to scrape away debris from the grinding stone 54 more thoroughly, so that the grinding stone 54 can more effectively polish the tip of the periodontal scaling instrument.

[0051] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
