Description

Technical Field

[0001] This utility model relates to the field of implant removal devices, and more particularly to a universal implant removal device. Background Technology

[0002] An implant is an artificial structure surgically inserted into the jawbone to replace the roots of missing teeth and provide stable support for the upper restorations (such as crowns and dentures).

[0003] Implants are prone to breakage when the occlusal load is too high. In this case, the damaged implant needs to be removed. Because the space inside the human mouth is small, it is difficult to insert electric instruments into the mouth to remove the implant. The implant can only be removed by manual tools. Due to the narrow space inside the mouth, it is difficult to apply force to the implant manually, making it inconvenient to remove it quickly. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a universal implant removal device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a universal implant removal device, comprising a handle, an assisting part, and a removal part, wherein the removal part is installed at one end of the handle, and the removal part is threadedly engaged with the internal threads of the implant through a surface thread, and the assisting part is inserted into the handle to increase the rotational torque of the removal part, thereby assisting in the removal of the implant.

[0006] The effect achieved by the above-mentioned components is that the removal part is screwed into the implant screw hole, and then the handle part and the implant can be connected, thereby extending the implant out and making it easy to remove the implant.

[0007] Preferably, the handle portion includes a first handle and a second handle, wherein a countersunk screw hole is formed on the surface of the first handle, a screw is inserted into the countersunk screw hole and passes through the thread of the first handle and screwed onto the second handle to attach the first handle and the second handle together; wherein the removal portion includes a first half thread and a second half thread, the first half thread is fixed to the first handle, and the second half thread is fixed to the second handle, wherein when the first handle and the second handle are combined, the first half thread and the second half thread can form a complete thread structure, and also includes a hexagonal hole, wherein the hexagonal hole is formed on the handle portion, and the assist portion is inserted into the hexagonal hole and assembled with the handle portion.

[0008] The above components achieve the following effects: the first handle and the second handle can be separated by removing the bolts, making it easy to carry; the assist part is inserted into the handle to increase the torque.

[0009] Preferably, the screw port is fixedly connected to a disc structure, wherein the edge of the disc structure is provided with anti-slip protrusions.

[0010] The effect achieved by the above components is that the disc-mounted structure can be manually turned to facilitate the removal of screws.

[0011] Preferably, a positioning part is provided between the first handle and the second handle to restrict their positions.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, the removal part is screwed into the screw hole of the implant, and then the handle part and the implant can be connected, thereby extending the implant out and making it convenient to remove the implant.

[0014] 2. In this utility model, the distance between the first handle and the second handle can be adjusted so that the first half-filament and the second half-filament can be fitted inside the implant to fit different implants. Attached Figure Description

[0018] Example 1, as Figure 1-2As shown, a universal implant retrieval device includes a handle 1, an assisting part 2, and a retrieval part 3. The retrieval part 3 is installed at one end of the handle 1. The retrieval part 3 is threadedly engaged with the internal threads of the implant. The assisting part 2, inserted into the handle 1, increases the rotational torque of the retrieval part 3, thereby assisting in the removal of the implant. The handle 1 includes a first handle 11 and a second handle 12. The surface of the first handle 11 has a countersunk screw hole 5, and a screw 6 is inserted into the countersunk screw hole 5 and passes through the first handle 11 and threaded onto the second handle 12. The first handle 11 and the second handle 12 are attached together on the handle 12; the take-out part 3 includes a first half thread 31 and a second half thread 32. The first half thread 31 is fixed to the first handle 11, and the second half thread 32 is fixed to the second handle 12. When the first handle 11 and the second handle 12 are combined, the first half thread 31 and the second half thread 32 can form a complete thread structure. It also includes a hexagonal hole 4, which is opened on the handle part 1. The assisting part 2 is inserted into the hexagonal hole 4 and assembled with the handle part 1.

[0019] The working principle is as follows: the removal part 3 is screwed into the implant screw hole, and then the handle part 1 and the implant can be connected, so that the implant can be extended out for easy removal. The handle part 1 can be separated into the first handle 11 and the second handle 12 by removing the bolt, which is convenient for carrying. Alternatively, the bolt thread can be passed through the second handle 12 first, and the length of the extended second handle 12 can be adjusted by rotating the bolt. Then the first handle 11 is connected to the bolt extension port, so that the distance between the first handle 11 and the second handle 12 can be adjusted, so that the first half thread 31 and the second half thread 32 are locked inside the implant to adapt to different implants. The assist part 2 is inserted into the handle part 1 to increase the torque.
