Description

Technical Field

[0001] The present invention relates to the technical field of oral medical instruments, and in particular to an implant removal device. Background Art

[0002] Oral implants are artificial parts that are surgically implanted into the alveolar bone of the upper and lower jaws. They are usually made of biocompatible materials such as titanium or titanium alloys and are shaped like screws or columns. Their function is to replace natural tooth roots and support restorations such as crowns, bridges or dentures. After being implanted in the alveolar bone for a period of time, they will form a strong bone bond with it, thereby providing stable support for the missing teeth.

[0003] Oral implants sometimes need to be removed, and the main reasons cover many aspects. First, peri-implantitis is a common cause of implant failure. If the surrounding tissue is severely infected and conventional treatment cannot be controlled, the implant may need to be removed to prevent the spread of infection and further damage to the alveolar bone. For example, a patient had severe inflammation around the implant due to poor oral hygiene after undergoing implant surgery, and had to be removed after multiple treatments failed. Second, loose implants can also lead to the need for removal, which may be due to poor integration of the implant with the alveolar bone, excessive bite force or other mechanical factors, making it unable to stably support the upper restoration. Third, when the alveolar bone around the implant is excessively absorbed, affecting stability and function, it may need to be removed. Fourth, when the implant is improperly implanted during implant surgery, affecting the occlusion, aesthetics or health of adjacent teeth, it may need to be removed and re-implanted. Finally, changes in the patient's physical condition, such as severe systemic diseases that cannot tolerate implants, or treatment of other diseases to avoid mutual influence, may also require the removal of implants.

[0004] Within the scope of the prior art, when starting to remove oral implants, one must rely on two types of tools: an extractor and a manual torque wrench. Specifically, the extractor will probe into the oral cavity and precisely match the implant. At the same time, the manual torque wrench also needs to be inserted into the oral cavity and fit with the clamping part of the extractor. Thereafter, the implant can be screwed out by turning the torque wrench. However, the unavoidable situation is that the space inside the oral cavity is extremely narrow. Such an environment makes it difficult to provide sufficient space for the torque wrench to rotate, making it difficult to rotate smoothly, which in turn leads to inconvenient operation and adds many difficulties and troubles to the entire removal process.

[0005] In summary, the removal of oral implants is crucial to the patient's oral health and subsequent treatment. If the removal process is difficult due to the limitations of operating tools and space, it will not only increase the patient's pain and treatment time, but may also affect the treatment effect and even cause complications. Therefore, it is urgent to seek more convenient and efficient methods and tools for oral implant removal. Summary of the invention

[0019] Wherein, the mounting column is detachably provided with a damping ring, and the damping ring is used to abut against the first connecting member and / or the first clamping member on the clamping portion.

[0020] A further technical solution is that a transmission cavity is provided in both the first connecting member and the second connecting member, and the transmission cavity is communicated with the through hole of the first connecting member, or the through hole of the second connecting member, and a plane gear is rotatably provided in the transmission cavity;

At this time, the second transmission rod will be adaptively extended and contracted relative to the first transmission rod until the second clamping member extends out of the patient's mouth. Next, the second clamping member is externally connected to the torque wrench to drive the second clamping member to rotate. When the second clamping member rotates, it will drive the first transmission rod to rotate synchronously, and the first transmission rod drives the docking part to rotate through the clamping part, and finally the implant is screwed out and the implant is removed. In the above whole process, the power input of the extractor body is located outside the oral cavity. Compared with the traditional operation method in which the torque wrench is operated inside the oral cavity, this design provides sufficient space for the rotation of the torque wrench, making the operation easier.

DETAILED DESCRIPTION

[0040] Example

[0041] Please refer to Figure 1-Figure 11 , an implant removal device, comprising:

[0042] The extractor body 100 is provided with a docking portion 101 and a clamping portion 104, wherein the docking portion 101 is used to dock with the implant, and the docking portion 101 is a hexagonal column;

[0043] A first transmission assembly includes a first connecting member 200, a first clamping member 201 and a first transmission rod 202, wherein the first clamping member 201 is connected with the clamping portion 104, and the first clamping member 201 is rotatably disposed on the first connecting member 200, and the first transmission rod 202 is rotatably disposed on the first connecting member 200, and the first transmission rod 202 and the first clamping member 201 are in transmission cooperation, and when the first transmission rod 202 rotates, the first clamping member 201 drives the docking portion 101 to rotate through the clamping portion 104; and

[0044] The second transmission assembly includes a second connecting member 300, a second transmission rod 302 and a second clamping member 301 for an external torque wrench. The second clamping member 301 can be rotatably set on the second connecting member 300. One end of the second transmission rod 302 can be telescopically set on the first transmission rod 202, and the other end is transmission-coordinated with the second clamping member 301. The second connecting member 300 can be telescopically set on the first connecting member 200, and the second connecting member 300 and the second transmission rod 302 can be telescopically extended and retracted synchronously in the same direction. When the external torque wrench of the second clamping member 301 rotates, the second transmission rod 302 drives the first transmission rod 202 to rotate.

[0045] When the extraction device of the present application is actually put into use, the docking part 101 of the extractor body 100 is first accurately positioned on the implant, and then the second connecting member 300 is adjusted to be telescopic relative to the first connecting member 200. At this time, the second transmission rod 302 will be adaptively telescopic relative to the first transmission rod 202 until the second clamping member 301 extends out of the patient's oral cavity. Next, the second clamping member 301 is externally connected to the torque wrench to drive the second clamping member 301 to rotate. When the second clamping member 301 rotates, it will drive the first transmission rod 202 to rotate synchronously, and the first transmission rod 202 drives the docking part 101 to rotate through the clamping part 104, and finally the implant is screwed out, and the implant is removed. In the above whole process, the power input of the extractor body 100 is located outside the oral cavity. Compared with the traditional operation method in which the torque wrench is operated inside the oral cavity, this design provides sufficient space for the rotation of the torque wrench, making the operation easier. This advantage not only significantly improves the convenience and efficiency of operation, but also greatly reduces the risk of errors caused by limited operating space, and is highly practical.

[0046] In addition, by flexibly adjusting the extension and retraction of the second connecting member 300 relative to the first connecting member 200, the second transmission rod 302 can be adaptively extended and retracted relative to the first transmission rod 202, so that the position of the second clamping member 301 can be adjusted according to actual conditions. Implants in different positions, whether near the outside or inside of the oral cavity, can be accurately removed through this adjustment. This feature greatly expands the scope of use of the device, allowing it to be at ease in the face of various complex oral conditions, showing greater flexibility, and bringing more possibilities and convenience to the removal of oral implants.

[0047] In some embodiments of the present invention, the clamping portion 104 is a hexagonal prism;

[0048] The first clamping member 201 and the second clamping member 301 both include an annular member, which is rotatably disposed on the first connecting member 200 or the second connecting member 300, and a hexagonal notch is disposed on the inner side of the annular member, wherein the hexagonal notch is used to adapt to the clamping portion 104 or the torque wrench.

[0049] In the above embodiment, the docking portion 101 and the clamping portion 104 are coaxially arranged. The annular member is sleeved on the clamping portion 104, and the two are closely fitted relative to each other. As a result, when the annular member rotates, a rotational force can be effectively applied to the clamping portion 104. This rotational force can be smoothly transmitted to the clamping portion 104, thereby driving the docking portion 101 to rotate, and finally successfully achieving the removal of the implant.

[0050] Specifically, the annular member of the first clamping member 201 and the annular member of the second clamping member 301 are not only completely identical in shape, but also in size. This feature is of great significance, so that in the actual use of the device, the first transmission assembly and the second transmission assembly have the possibility of being used interchangeably. This undoubtedly greatly enhances the flexibility of the use of the device and can better adapt to various different actual application scenarios and needs.

[0051] In some embodiments of the present invention, the first connecting member 200 and the second connecting member 300 are both provided with a through hole 306, and the through hole 306 is used to adapt to the rotation of the ring member of the first connecting member 200 or the rotation of the ring member of the second connecting member 300;

[0052] The clamping portion 104 is disposed at the end of the extractor body 100 and is used for detachably cooperating with the annular member of the first connecting member 200 .

[0053] In the above embodiment, the clamping portion 104 is arranged at the end of the extractor body 100, so that it is convenient to plug and match with the annular member of the first connecting member 200, thereby realizing the detachable arrangement of the extractor body 100 and the first transmission assembly. In this way, the device can be disassembled into two separate units, which is more convenient for storage.

[0054] In some embodiments of the present invention, the extractor body 100 further includes a telescopic rod, and the clamping portion 104 and the docking portion 101 are respectively disposed at two ends of the telescopic rod.

[0055] In the above embodiment, the design of the telescopic rod can adaptively adjust the height of the extractor body 100. If there are obstacles around the clamping portion 104 (such as adjacent implants), the height of the clamping portion 104 can be adjusted to facilitate the reasonable arrangement of the first transmission assembly.

[0056] In some embodiments of the present invention, the telescopic rod includes a first column 102 and a second column 103, one end of the first column 102 is connected to the docking portion 101, and the other end is provided with a first telescopic groove 108, the second column 103 can be telescopically arranged in the first telescopic groove 108, and one end of the second column 103 passes through the first telescopic groove 108 and is connected to the clamping portion 104.

[0057] In the above embodiment, the telescopic cooperation between the first column 102 and the second column 103 can adjust the height of the clamping portion 104 .

[0058] Specifically, the first telescopic groove 108 includes a central groove and a slide groove that are interconnected. The central groove is located in the middle of the first column 102, and one end of the central groove passes through the side of the first column 102 to adapt to the insertion of the second column 103; the slide groove is located on the side of the central groove, and the guide groove is in an internal closed state (that is, both ends do not pass through the two ends of the first column 102). The second column 103 covers the central column and the slider, the central column cooperates with the central groove, and the slide groove and the slider slide in cooperation. This telescopic structure can not only realize the relative sliding of the first column 102 and the second column 103, but also prevent the second column 103 from slipping off the first column 102. In addition, the cooperation of the slider and the slide groove can also effectively prevent the second column 103 from rotating relative to the first column 102.

[0059] Furthermore, the first telescopic groove 108 also includes a plurality of hemispherical grooves 107. The hemispherical grooves 107 are located on the side of the central groove, and the plurality of hemispherical grooves 107 are evenly spaced along the extension direction of the central groove. The central column is provided with a positioning groove 110, and when the central column is extended, the positioning groove 110 can be docked with the plurality of hemispherical grooves 107 in sequence. A spring 111 is provided in the positioning groove 110, and a hemispherical block 109 is provided at the outer end of the spring 111. When the hemispherical block 109 docks with one of the hemispherical grooves 107 under the action of the spring 111, the relative locking of the first column 102 and the second column 103 can be achieved. The second column 103 can only be extended and retracted when the force applied to the second column 103 is greater than the limiting action of the spring 111; otherwise, the second column 103 remains stationary.

[0060] In some embodiments of the present invention, a mounting post 106 is provided on a side of the clamping portion 104 away from the docking portion 101, and the annular member of the first connecting member 200 can pass through the mounting post 106;

[0061] The mounting column 106 is detachably provided with a damping ring 105 , and the damping ring 105 is used to abut against the first connecting member 200 and / or the first clamping member 201 on the clamping portion 104 .

[0062] In the above embodiment, the damping ring 105 on the mounting column 106 can limit the first transmission assembly, prevent the first transmission assembly from slipping off the clamping portion 104, and improve the stability of the connection between the first transmission assembly and the extractor body 100.

[0063] In some embodiments of the present invention, a transmission cavity 307 is disposed in both the first connecting member 200 and the second connecting member 300, and the transmission cavity 307 is communicated with the through hole 306 of the first connecting member 200, or the through hole 306 of the second connecting member 300, and a plane gear 600 is rotatably disposed in the transmission cavity 307;

[0064] Among them, the outer ring surface of the annular part of the above-mentioned first connecting member 200 and the outer ring surface of the annular part of the above-mentioned second connecting member 300 are both provided with a toothed belt 500, the above-mentioned toothed belt 500 is meshed with the above-mentioned planar gear 600, and the above-mentioned planar gear 600 is transmission-connected to the above-mentioned first transmission rod 202 or the above-mentioned second transmission rod 302 through the bevel gear set 400.

[0065] In the above embodiment, the two sets of bevel gear sets 400 and the two sets of plane gears 600 are carefully designed to achieve the transmission coordination between the first clamping member 201, the first transmission rod 202, the second transmission rod 302 and the second clamping member 301. In this way, the force of the second clamping member 301 (driven by the twisting wrench) can be input to the first clamping member 201, thereby realizing the rotation adjustment of the extractor body 100. In actual use, by using the twisting wrench to rotate the second clamping member 301 forward or reversely, the extractor body 100 can be rotated forward or reversed, thereby smoothly removing the implant.

[0066] In some embodiments of the present invention, a second telescopic slot 303 is provided at one end of the second transmission rod 302 away from the second clamping member 301 , and one end of the first transmission rod 202 away from the first clamping member 201 is telescopically matched with the second telescopic slot 303 .

[0067] In the above embodiment, the second transmission rod 302 is rotatably disposed in the second connecting member 300, and one end of the second transmission rod 302 away from the second clamping member 301 passes through the outer side of the second connecting member 300 and extends into the first connecting member 200. The second transmission rod 302 extending into the first connecting member 200 is telescopically matched with the first transmission rod 202 (the first connecting member 200 is provided with a notch adapted to the telescopic extension of the second transmission rod 302).

[0068] Specifically, a guide slider 203 is provided on the ring side of the first transmission rod 202, and the second transmission rod 302 is provided with a guide slot 304 (in an internally closed state) that slides with the guide slider 203. The sliding cooperation between the guide slider 203 and the guide slot 304 can improve the stability of the relative telescopic movement of the first transmission rod 202 and the second transmission rod 302.

[0069] In some embodiments of the present invention, the first connecting member 200 is provided with a second telescopic slot 303 , and the second connecting member 300 is provided with a guide column 305 that telescopically cooperates with the second telescopic slot 303 .

[0070] In the above embodiment, the design of the guide column 305 , on the one hand, connects the first connecting member 200 and the second connecting member 300 into a whole; on the other hand, it realizes the relative expansion and contraction of the second connecting member 300 and the first connecting member 200 .

[0071] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
