[0002] Oral implant technology has become a routine and reliable means for repairing tooth defects or loss. However, in clinical practice, some implants may need to be surgically removed due to various reasons such as peri-implantitis, implant loosening, surgical failure, implant fracture, or poor position, etc. Implants that fail to be removed or have complications are a challenging operation in oral implant restoration.

[0003] However, the existing extraction instruments (such as extraction wrenches, grabbers, etc.) mostly rely on the single direction, point or line occlusion of the implant internal thread or interface, and have problems such as insufficient clamping force, small contact area, stress concentration, etc. During the operation process, the instrument is prone to slipping, the implant is difficult to effectively grasp, and even the implant may fall into the patient's throat or trachea, which has certain safety hazards. At the same time, the operation steps of some instruments are complicated, and the doctor needs to cooperate with both hands and repeatedly adjust, which is not conducive to efficiently and stably extracting the oral implant.

[0004] Therefore, in order to solve the above problems, the present application provides a stable, reliable and easy-to-operate implant extraction instrument, thereby improving the success rate of oral implant extraction and reducing the risk of surgery. SUMMARY

[0013] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments: like Figs. 1-3 The dental implant removal device and apparatus shown include a handle 1, with a removal handle 2 fixedly connected to the left side of the handle 1. Both the handle 1 and the removal handle 2 are cylindrical structures, and the handle 1 and the removal handle 2 are connected to form an L-shaped structure. Three sliding grooves 21 are arranged in a circular array at the lower end of the removal handle 2. Each sliding groove 21 is also provided with a limiting groove 25 on both sides. The top of the inner abutment 5 is slidably connected to the inside of the sliding grooves 21 and the limiting grooves 25. A first spring 22 is connected in each sliding groove 21. The two ends of the spring 22 are respectively connected to the side wall of the sliding groove 21 and the side wall of the inner abutment plate 5. The inner part of the inner abutment plate 5 is provided with a wedge-shaped structure. The adjusting rod 3 passes through the take-out handle 2 from top to bottom. The lower part of the adjusting rod 3 is connected to the fixing ring 31. The fixing ring 31 abuts against the wedge-shaped structure of the inner abutment plate 5. Therefore, when the fixing ring 31 moves upward, the inner abutment plate 5 will move outward along the sliding groove 21. The top of the inner abutment plate 5 is fixedly connected to a cylindrical fixing block 32. The bottom ends of the fixing block 32 are fixedly connected to two limit rods 33. The bottom end of the 33 is fixedly connected to the locking block 34. The limiting rod 33 slides inside the extraction handle 2. A second spring 35 is sleeved on the outside of the limiting rod 33. The two ends of the second spring 35 are respectively connected to the bottom of the fixing block 32 and the top of the extraction handle 2. The middle position of the adjusting frame 4 is rotatably connected to the grip handle 1. The left end of the adjusting frame 4 is rotatably connected to both sides of the fixing block 32. An observation mirror 6 is rotatably connected to the side wall of the extraction handle 2. A sliding groove 23 is provided on the side wall of the extraction handle 2. The upper side of the sliding groove 23 is rotatably connected to an outer... The abutment plate 24 and the sliding groove 23 are internally connected to the take-out handle 2. The side wall of the adjusting rod 3 is fixedly connected to the sliding block 36, which is slidably connected in the sliding groove 23. The top of the sliding block 36 is rotatably connected to the connecting rod 37. One end of the connecting rod 37 is rotatably connected to the sliding block 36, and the other end is rotatably connected to the outer abutment plate 24. Both the outer abutment plate 24 and the inner abutment plate 5 are provided with a frosted area 7, which is used to increase friction. The part of the grip handle 1 located on the right side of the adjusting frame 4 can be set as a telescopic structure for length adjustment.

[0014] The specific implementation process is as follows: The device of the present invention is used to remove oral implants that have been rotated and loosened. During removal, hold the handle 1 by hand and insert the removal handle 2 into the oral cavity. The oral cavity can be observed through the observation mirror 6. Insert the inner abutment 5 into the implant. The outer abutment 24 is located on the outside of the implant. When in use, simply press down the adjusting frame 4. The adjusting frame 4 rotates and drives the fixing block 32 to move upward. The upward movement of the fixing block 32 causes the adjusting rod 3 to move upward. The upward movement of the adjusting rod 3 causes the fixing ring 31 to move upward. Since the fixing ring 31 abuts against the wedge-shaped structure of the inner abutment 5, the inner abutment 5 moves outward. When the adjusting rod 3 moves upward, it will drive the sliding block 36 to move upward, causing the connecting rod 37 to rotate inward. The rotation of the connecting rod 37 inward causes the outer abutment 24 to rotate closer to the inner abutment 5. The inner abutment 5 moves outward, and the outer abutment 24 moves inward, thereby clamping the oral implant. By keeping the adjusting frame 4 pressed down, the oral implant can be removed. This device has a simple structure and is easy to use. It can effectively ensure that dental implants can be effectively removed, and effectively reduce or avoid the risk of dental implants falling out.

For those skilled in the art, various modifications and improvements can be made without departing from the technical solutions of the present invention, and these should also be considered within the scope of protection of the present invention. These modifications and improvements will not affect the effectiveness of the implementation of the present invention or the practicality of the patent.
