Description

Technical Field

[0001] The invention relates to the technical field of dental implant tools, and in particular to an implant removal tool set. Background Art

[0003] However, one of the common mechanical complications in dental implant restoration is the breakage of the central fixing screw of the restoration base. The current tool box for handling broken screws has the problem of single applicability and cannot fully match the approximately 300 implant systems circulating on the market. Since the internal interface shape, repair screw length and diameter of different implant systems are different, the length requirements for the adapter to extend into the broken screw are different, and the adapter in the existing tool box cannot be directly, accurately and stably installed on the implant internal interface, which is prone to clinical misoperation during use, which may cause damage to the implant thread.

[0004] Therefore, the present application studies an implant removal tool set, which can effectively handle broken screws while protecting the threads inside the implant from damage. Summary of the invention

[0005] In order to protect the threads inside the implant from being damaged while effectively handling broken screws, the present application provides an implant removal tool set.

[0006] The present application provides a implant removal tool set, which adopts the following technical solution:

[0007] A implant removal tool set includes a drill needle and several different adapters, wherein the outer circumference of the drill needle is provided with multiple layers of abutment steps, and the inner circumference of the adapter is provided with a limiting step that cooperates with at least one layer of the abutment steps, the outer diameter of the drill needle between each layer of the abutment steps gradually decreases toward the drill bit direction of the drill needle, and the inner diameter of the adapter matches the outer diameter of the drill needle; when engaged, the drill needle extends into the adapter, the outer circumference of the drill needle fits with the inner circumference of the adapter, the abutment steps abut against the limiting steps, and one end of the drill bit of the drill needle extends out of the adapter, and the length of the drill bit of the drill needle extending out of different adapters is different.

[0008] By adopting the above technical scheme, the drill is used to process broken screws, and the type and quantity of adapters are set according to the implant system to meet the internal interface shape and size requirements of different implant systems. The cooperation of the limiting step and the abutment step enables the drill to be stably positioned in the adapter to avoid the drill bit of the drill extending too long and entering too deep into the implant, resulting in cutting to the bottom of the cavity in the implant and penetrating the implant; at the same time, it is avoided that shaking or dislocation occurs during operation. By selecting different adapters, the drill bit of the drill can extend to different lengths from the adapter, which can adapt to the depth and position differences of broken screws in different implant systems, thereby improving the versatility and flexibility of the tool set, so that the broken screws can be effectively processed while protecting the threads in the implant from damage.

[0009] Optionally, the abutment step is arranged to be inclined toward the drill needle from a side of the drill bit away from the drill needle to a side of the drill bit close to the drill needle, and the limiting step matches the abutment step.

[0010] By adopting the above technical solution, while playing a guiding role, it can prevent the drill from shaking in the adapter and ensure that the drill remains stable during operation, reducing the risk of damage to the implant thread due to improper operation.

[0011] Optionally, the limiting steps and the abutting steps are arranged in a corresponding number and matched one by one.

[0012] By adopting the above technical solution, it is ensured that each limiting step can cooperate with an abutment step, so that the abutment of the drill needle can be better guaranteed, and the shaking and misalignment during the operation are reduced.

[0013] Optionally, the height of the abutting step is 0.2 mm.

[0014] Optionally, four abutment steps are provided, and the distances between the abutment steps from the drill bit side away from the drill needle to the drill bit side close to the drill needle are 5 mm, 1 mm, and 1 mm, respectively.

[0015] Optionally, the drill bit diameter of the drill needle is 0.8 mm.

[0016] Optionally, two opposite sides of the drill bit of the drill needle have clearance grooves to form a drilling portion.

[0017] In summary, this application includes the following beneficial technical effects:

[0018] 1. The drill is used to process broken screws. The type and quantity of adapters are set according to the implant system to meet the requirements of the internal interface shape and size of different implant systems. The cooperation of the limit step and the abutment step enables the drill to be stably positioned in the adapter to prevent the drill bit of the drill from extending too long and entering too deep into the implant, resulting in cutting to the bottom of the cavity in the implant and penetrating the implant; at the same time, it is prevented from shaking or dislocation during operation. By selecting different adapters, the drill bit of the drill can extend to different lengths from the adapter, which can adapt to the depth and position differences of broken screws in different implant systems, improve the versatility and flexibility of the tool set, so that the broken screws can be effectively processed while protecting the threads in the implant from damage;

[0019] 2. While serving as a guide limiter, it prevents the drill from shaking in the adapter and ensures that the drill remains stable during operation, reducing the risk of thread damage in the implant due to improper operation;

[0020] 3. Ensure that each limit step can cooperate with an abutment step, so that the drill bit can be better abutted and the shaking and misalignment during operation can be reduced. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The following is combined with Figure 1-8 This application is described in further detail.

[0033] The present application embodiment discloses a plant removal tool set. Figure 1-Figure 4 The implant removal tool set includes a drill 1 and several different adapters 2 (only part of them are shown in the figure, and other adapters 2 of any different shapes can also be used). The drill 1 is inserted into the adapter 2, and the adapter 2 is used to limit the extension length of the drill 1, thereby limiting the length of the drill 1 inserted into the implant. In different scenarios, the adapter 2 is accurately used to limit the length of the drill 1 to adapt to the required scenario. The precise positioning of the adapter 2 can ensure that the punching drill does not deviate horizontally, ensure that the internal thread of the implant side wall is not damaged while cutting and drilling the broken screw, and ensure the accuracy of the implant for continued use in the later stage.

[0034] Reference Figure 5-Figure 8 The outer circumference of the drill needle 1 is provided with multiple layers of abutment steps 3, and the inner circumference of the adapter 2 is provided with a limiting step 4 that cooperates with at least one layer of abutment step 3. The outer diameter of the drill needle 1 between each layer of abutment step 3 gradually decreases toward the drill bit direction of the drill needle 1, and the inner diameter of the adapter 2 matches the outer diameter of the drill needle 1.

[0035] When mating, the drill needle 1 is inserted into the adapter 2, the abutment step 3 abuts against the limiting step 4, the outer circumference of the drill needle 1 fits against the inner circumference of the adapter 2, and one end of the drill bit of the drill needle 1 extends out of the adapter 2. The drill bit of the drill needle 1 extends out to different lengths on different adapters 2. By limiting the extension length of the drill needle 1 with different adapters 2, it is possible to adapt to the depth and position differences of broken screws in different implant systems, thereby effectively handling broken screws while protecting the threads in the implant from damage.

[0036] Reference Figure 5In some embodiments, the abutting step 3 is inclined toward the drill needle 1 from the drill bit side away from the drill needle 1 to the drill bit side close to the drill needle 1, and the limiting step 4 matches the abutting step 3. When the drill needle 1 is inserted into the adapter 2, the inclined abutting step 3 can play a guiding role, and the inclined abutting step 3 can be more stable after matching with the limiting step 4.

[0037] In some embodiments, the number of the limiting steps 4 and the abutting steps 3 are correspondingly arranged and matched one by one, so that each layer of abutting steps 3 can match one by one with the limiting steps 4, so that after the drill needle 1 is inserted into the adapter 2, it can be more stably limited in the adapter 2.

[0038] In some embodiments, the height of the abutment step 3 is 0.2 mm.

[0039] In some embodiments, four abutment steps 3 are provided, and the distances between the abutment steps 3 from the drill bit side away from the drill needle 1 to the drill bit side close to the drill needle 1 are 5 mm, 1 mm, and 1 mm, respectively. The abutment step 3 close to the drill bit of the drill needle 1 is designed as a precautionary measure, and it is determined whether the last layer of limiting step 4 is to be designed in the adapter 2 to abut against the abutment step 3 according to the exposed length of the screw. Therefore, in other embodiments, the number of limiting steps 4 can be at least one less than the number of abutment steps 3.

[0040] In some embodiments, the drill bit diameter of the drill needle 1 is 0.8 mm. After the abutting step 3 and the limiting step 4 of this embodiment cooperate, the drill needle 1 can still operate within the safety range of ensuring the side wall strength of the broken screw when the drill bit diameter is only 0.8 mm, that is, after drilling, it can at least ensure that the broken screw has a side wall thickness of more than 0.35 mm to prevent the side wall from being too thin and deformed.

[0041] In some embodiments, two opposite sides of the drill bit of the drill needle 1 have relief grooves 5 and form a drilling portion 6, so that the broken screw can be operated better.

[0042] The implementation principle of an implant removal tool set in an embodiment of the present application is as follows: the drill needle 1 is used to process broken screws, and the type and quantity of adapters 2 are set according to the implant system to meet the internal interface shape and size requirements of different implant systems. The cooperation between the limiting step 4 and the abutment step 3 enables the drill needle 1 to be stably positioned in the adapter 2, thereby preventing the drill bit of the drill needle 1 from extending too long and entering too deep into the implant, thereby cutting into the bottom of the cavity in the implant and penetrating the implant; at the same time, avoiding shaking or dislocation during operation. By selecting different adapters 2, the drill bit of the drill needle 1 can extend out of the adapter 2 to different lengths, which can adapt to the depth and position differences of broken screws in different implant systems, thereby improving the versatility and flexibility of the tool set, thereby effectively processing broken screws while protecting the threads in the implant from damage.
