Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, specifically relating to a dental implant removal device. Background Technology

[0002] Dental implants are a method of tooth restoration that uses a substructure implanted into the bone tissue to support and retain the superstructure of the prosthesis. It consists of two parts: the supporting implant and the superstructure prosthesis. The implant, made of artificial materials such as metal or ceramic (generally resembling a tooth root), is surgically implanted into the bone tissue (usually the upper or lower jaw) and securely supported by the bone. It is then connected to the superstructure prosthesis using specialized devices and methods. Dental implants can achieve restorative results very similar to natural teeth in terms of function, structure, and aesthetics, and have become the preferred restoration method for an increasing number of patients with missing teeth.

[0003] When dental implants are damaged due to external forces or other factors, the implant dentist needs to remove the implants that have been placed in the alveolar bone. Currently, the implant is usually first rotated outwards. Once the implant dentist believes it is in a rotated position, forceps and tweezers are used to remove it. However, this method requires changing different tools during implant removal, which not only reduces efficiency but also poses a significant risk if a loose implant falls into the patient's mouth and is accidentally swallowed, causing unnecessary complications. Utility Model Content

[0004] The purpose of this invention is to provide a dental implant removal device that can solve the above-mentioned technical problems.

[0005] The specific technical solution adopted by this utility model is as follows:

[0006] This utility model provides a dental implant removal device, including a base ring and a linkage mechanism. A drive shaft is fixedly mounted on the base ring, and a movable column is movably sleeved on the drive shaft. Two symmetrical locking grooves are formed on the outer circumferential surface of the movable column. A sleeve plate is provided on the upper side of the movable column. The sleeve plate and the two locking grooves are connected to the linkage mechanism. A hexagonal nut is provided on the upper side of the drive shaft. A torsion plate matching the inner groove of the dental implant is provided on the bottom surface of the base ring.

[0007] The linkage mechanism includes a slider that is slidably disposed in a slot, a spring disposed on the bottom surface of the slider, the lower side of the spring disposed on the bottom surface of the slot, a flipping mechanism and a pushing mechanism for pressing down the flipping mechanism to move down on the slider, a support plate disposed on the upper side of the movable column, a flipping mechanism disposed on the support plate, the flipping mechanism being connected to both the flipping mechanism and the pushing mechanism, and a gripping plate disposed on the support plate;

[0008] The flipping mechanism includes a fastening cover and a flipping plate. A stabilizing shaft is movably sleeved on the flipping plate. The stabilizing shaft is detachably mounted on the slider through the fastening cover. An expansion plate is provided on the bottom surface of the flipping plate, and a slot plate is provided on the bottom surface of the expansion plate.

[0009] Using the aforementioned dental implant removal device, by grasping the grip plate and pulling the lever plate on the linkage mechanism with one's fingers, the lever plate rotates along the fourth shaft. Simultaneously, the rotation of the lever plate drives the first and second push-pull plates on the flip-pull mechanism. The second push-pull plate pulls the rotating support plate and the lower push plate, causing the lower push plate to push the slider downwards along the slot. This also causes the slot plates on the flip plate and the outer expansion plate to move downwards to align with the torsion plate. Simultaneously, the downward movement of the flip plate causes the movable shaft to move upwards along the movable hole, thereby causing the second push-pull plate to pull the movable shaft. The movable shaft causes the flip plate to flip along the stabilizing shaft. At the same time, the flip plate causes the slot plate on the outer expansion plate to approach the torsion plate, thus clamping the implant with the slot plate and the torsion plate. This facilitates the clamping and removal of loose implants.

[0010] Preferably, the pushing mechanism includes a second shaft movably sleeved on the sleeve plate and two first shafts. The two ends of the second shaft are respectively provided with rotating support plates. The two first shafts are respectively provided on the lower side of the opposite side of the two rotating support plates. An extension plate is detachably provided on each of the two sliders. A sixth shaft is provided on the side of each of the two extension plates away from the slider. A pushing plate is rotatably provided on each of the two sixth shafts. One side of the pushing plate is rotatably engaged with the first shaft.

[0011] Preferably, a fourth set of shafts is movably sleeved on the support plate, and the fourth set of shafts is fixed on the gripping plate. A third set of shafts and a fifth set of shafts are provided on opposite sides of the gripping plate near the movable column. The gripping plate includes two connecting plates with a connection angle of 135°, and the gripping plate is formed with a concave hole that fits into the support plate.

[0012] Preferably, the flipping mechanism includes a first push-pull plate and a second push-pull plate, which are offset from each other. The lower side of the first push-pull plate is rotatably engaged with a first set of shafts, and the upper side of the first push-pull plate is rotatably engaged with a third set of shafts.

[0013] Preferably, the flip plate is provided with a movable hole, and a movable shaft is movably sleeved in the movable hole. The end of the movable shaft is rotatably engaged with the lower side of the second push-pull plate, and the upper side of the second push-pull plate is rotatably engaged with the fifth shaft.

[0014] Preferably, the stabilizing shaft is U-shaped and is fitted around the outer periphery of the movable column.

[0015] The beneficial effects are:

[0016] This invention utilizes a gripping and flipping mechanism to drive a flipping and pulling mechanism, which in turn moves a pushing mechanism. The pushing mechanism causes a slider to slide down the slot, which in turn causes the flipping mechanism to slide down. This causes the flipping plate to move down synchronously with the slot plate on the outer expansion plate to align with the implant. Simultaneously, with continuous gripping and pressing of the gripping and flipping plate, the second push-pull plate drives the flipping plate to flip against the stabilizing shaft. This allows the flipping plate to engage with the slot plate and the twisting plate to clamp the implant. This allows the implant to be loosened by rotation and then clamped for removal, thereby improving removal efficiency and reducing the risk of the implant falling out of the mouth after loosening.

[0022] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0023] like Figure 1-3As shown, a dental implant removal device includes a base ring 1 and a linkage mechanism 4. A drive shaft 6 is fixed on the base ring 1, and a movable column 2 is movably sleeved on the drive shaft 6. Two symmetrical slots 3 are formed on the outer circumferential surface of the movable column 2. A sleeve plate 5 is provided on the upper side of the movable column 2. The sleeve plate 5 and the two slots are connected to the linkage mechanism 4. A hexagonal nut 7 is provided on the upper side of the drive shaft 6. A torsion plate 10 matching the inner groove of the implant is provided on the bottom surface of the base ring 1.

[0024] The linkage mechanism 4 includes a slider 401 that is slidably disposed in the slot 3. A spring 407 is disposed on the bottom surface of the slider 401. The lower side of the spring 407 is disposed on the bottom surface of the slot. A flipping mechanism and a pushing mechanism for pressing down the flipping mechanism are provided on the slider 401. A support plate 8 is disposed on the upper side of the movable column 2. A flipping mechanism is disposed on the support plate 8. The flipping mechanism is connected to both the flipping mechanism and the pushing mechanism. A gripping plate 9 is disposed on the support plate 8.

[0025] The flipping mechanism includes a fastening cover 402 and a flipping plate 404. A stabilizing shaft 403 is movably sleeved on the flipping plate 404. The stabilizing shaft 403 is detachably mounted on the slider 401 via the fastening cover 402. An expansion plate 405 is provided on the bottom surface of the flipping plate 404. A slot plate 406 is provided on the bottom surface of the expansion plate 405. The side of the slot plate 406 is provided with multiple slots. When the slot plate 406 cooperates with the sleeve twist plate 10 to clamp the implant, the slots are used to clamp the spiral teeth on the implant, thereby improving the clamping and fixing effect. The expansion plate 405 is provided with an obtuse V-shaped shape.

[0026] As an optional implementation, the pushing mechanism includes a second shaft 410 movably sleeved on the sleeve plate 5 and two first shafts 408. The two ends of the second shaft 410 are respectively provided with rotating support plates 409. The two first shafts 408 are respectively provided on the lower side of the opposite side of the two rotating support plates 409. The two sliders 401 are respectively provided with extension plates 420. The side of the two extension plates 420 away from the sliders 401 is respectively provided with a sixth shaft 421. The two sixth shafts 421 are respectively rotatably provided with a pushing plate 419. One side of the pushing plate 419 is rotatably engaged with the first shaft 408. With this configuration, the rotational engagement of the extension plate 420 and the pushing plate 419 can be used to make the pushing plate 419 flip and push the extension plate 420 and the slider 401 downward, thereby achieving the effect of pushing and moving downward.

[0027] See attached document Figure 1A fourth shaft 414 is movably sleeved on the support plate 8. The fourth shaft 414 is fixed on the grip plate 413. A third shaft 412 and a fifth shaft 415 are provided on opposite sides of the grip plate 413 near the movable column 2. The grip plate 413 includes two connecting plates with a connection angle of 135°. The grip plate 413 has a recessed hole formed on it to engage with the support plate 8. This arrangement allows the grip plate 413 to be sleeved on the support plate 8. By rotating the support plate 8 and the fourth shaft 414, the grip plate 413 can drive the first push-pull plate 411 and the second push-pull plate 416 to perform push-pull operations when it is close to the grip plate 9.

[0028] See attached document Figure 2 and attached Figure 3 The flipping mechanism includes a first push-pull plate 411 and a second push-pull plate 416. The first push-pull plate 411 and the second push-pull plate 416 are staggered. The lower side of the first push-pull plate 411 is rotatably engaged with the first set of shafts 408, and the upper side of the first push-pull plate 411 is rotatably engaged with the third set of shafts 412. With this arrangement, the first push-pull plate 411 can be used to pull the rotatable connection between the rotating support plate 409 and the lower push plate 419, thereby using the pushing to drive the lower push plate 419 to push the flipping mechanism downward.

[0029] Furthermore, the flipping plate 404 is provided with a movable hole 418, and a movable shaft 417 is movably fitted inside the movable hole 418. The end of the movable shaft 417 is rotatably engaged with the lower side of the second push-pull plate 416, and the upper side of the second push-pull plate 416 is rotatably engaged with the fifth set of shafts 415. With this arrangement, the length of the movable hole 418 can be used to respond to the downward movement of the flipping mechanism driven by the downward push mechanism. At the same time, the second push-pull plate 416 can simultaneously pull the movable shaft 417 upward along the movable hole 418 to respond to the downward movement of the flipping mechanism, without pulling the flipping plate 404. This allows the distance between the slot plate 406 and the sleeve torsion plate 10 to accommodate the clamping operation of the implant.

[0030] Furthermore, the stabilizing shaft 403 is U-shaped and is fitted around the outer periphery of the movable column 2. This ensures that when the stabilizing shaft 403 supports the flipping plate 404, it will not come into contact with the movable column 2, thus affecting the flipping operation of the flipping plate 404.

[0031] Using the above structure, by gripping the grip plate 9 and pulling the grip flap 413 on the linkage mechanism 4 with your fingers, the grip flap 413 rotates by the fourth set of shafts 414. At the same time, when the grip flap 413 rotates, it drives the first push-pull plate 411 and the second push-pull plate 416 on the flip-pull mechanism. The second push-pull plate 416 pulls the rotating support plate 409 and the lower push plate 419 to move, thereby causing the lower push plate 419 to push the slider 401 down along the slot 3, and at the same time drive the latches on the flip plate 404 and the expansion plate 405 to move. The groove plate 406 moves down to correspond with the sleeve twist plate 10. At the same time, the flip plate 404 moves down to make the movable shaft 417 move up along the movable hole 418, so that the second push-pull plate 416 pulls the movable shaft 417 to move. The movable shaft 417 drives the flip plate 404 to flip against the stabilizing shaft 403. At the same time, the flip plate 404 drives the slot plate 406 on the outer expansion plate 405 to approach the sleeve twist plate 10, so that the slot plate 406 and the sleeve twist plate 10 clamp the implant, which makes it easier to clamp and remove the loose implant.

[0032] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
