Description

TECHNICAL FIELD

[0001] The utility model relates to medical equipment technical field, concretely relates to a tool of dismantling and taking implant system base platform. BACKGROUND

[0002] In the dental implant repair process, after the implant completes osseointegration, sometimes secondary repair surgery is needed, and in this process, the installed base platform sometimes needs to be adjusted or replaced. The existing base platform and implant are usually connected by Morse taper, which is very tight, making it difficult to directly disassemble the base platform. There is a lack of effective special tools for disassembly on the market, and the commonly used method is to shake the base platform to make the Morse taper connection with the implant invalid and then take it out. However, this method has the following disadvantages:

[0003] 1. High risk of damage: The existing disassembly method mainly relies on manual shaking of the base platform, which not only damages the connection between the base platform and the implant, but also affects the health of the surrounding tissue, increasing the risk of surgery.

[0004] 2. Complex operation: Manual disassembly of the base platform requires a lot of strength and skill, and the operation process is complex and time-consuming, which is not conducive to improving surgical efficiency.

[0005] 3. Lack of special tools: There is a lack of tools specifically designed for disassembling the base platform on the market, and doctors often need to use other tools in actual operation, which increases the uncertainty and risk of surgery.

[0006] 4. Lack of precision: Manual operation cannot accurately control the force and direction during disassembly, which can easily damage the base platform and implant, affecting the repair effect.

[0007] Therefore, the existing technology has deficiencies and needs further improvement. INVENTION CONTENTS

[0063] Wrench interface 10: the top of the shaft 1 is also provided with a wrench interface 10 (preferably a hexagonal hole), which is convenient for doctors to use standard tools for rotating operation.

[0064] Lower end design: the lower end of the shaft 1 is a cylinder 11, and the end is provided with a rounded corner, which reduces the friction and damage to the inside of the implant 6.

[0065] Abutment 3 design:

[0066] The outer wall of the abutment 3 is provided with a tapered slope 12 for fastening when the abutment 3 is installed in the implant 6.

[0067] Specific working steps

[0068] Preparation:

[0069] Insert the shaft 1 into the first through hole 4 of the abutment 3, ensuring that the lower end of the shaft 1 abuts the bottom of the first mounting hole 7 of the implant 6.

[0070] Thread connection:

[0071] By rotating the shaft 1, the external threads of the shaft 1 and the internal threads of the inner hole of the abutment 3 are engaged with each other. As the shaft 1 rotates, the threads are gradually tightened.

[0072] Generate reaction force:

[0073] Continue to rotate the shaft 1, as the lower end of the shaft 1 abuts the bottom of the first mounting hole 7 of the implant 6, the tightening of the threads will generate an upward reaction force. This reaction force will gradually push the abutment 3 out of the implant 6.

[0075] Because the inner wall of the first mounting hole 7 is provided with a square hole 8 (preferably a regular hexagonal hole), and the lower end of the abutment 3 is also provided with a corresponding square shape, this can prevent the abutment 3 from rotating with the shaft 1 during disassembly, ensuring that the abutment 3 can be smoothly pushed out.

[0076] Disassemble the abutment 3:

[0077] As the shaft 1 continues to rotate, the upward reaction force on the abutment 3 gradually increases, eventually completely pushing the abutment 3 out of the implant 6.

[0078] Take out the tool:

[0079] After the abutment 3 is pushed out, reverse the rotation of the shaft 1 and rotate the shaft 1 out of the first through hole 4 of the abutment 3, completing the entire disassembly process.

[0080] Summary: Through the above design, the present application provides a simple structure, easy to operate, safe and reliable abutment 3 disassembly tool. The tool uses the principle of thread connection and reaction force, which can effectively disassemble the abutment 3 from the implant 6, while avoiding damage to the implant 6, protecting the osseointegration effect of the implant 6.
