Description

Technical Field

[0001] The utility model relates to the technical field of dental implants, in particular to a bone powder grinder for filling gaps in oral implants. Background Art

[0002] During the dental implant process, a positioning hole is punched on a press, and then the dental implant is inserted into the positioning hole. Since the aperture of the positioning hole is larger than the diameter of the dental implant, in order to ensure the stability of the implanted tooth, the gum bone particles taken out from the positioning hole will be ground into powder and filled around the implant in the positioning hole during the operation, so that the implant will not shake in the positioning hole, thereby improving the stability of the implant.

[0003] However, there is currently no special device for grinding gum bone particles into powder. Most dentists rely on using hard objects to crush the gum bone particles into powder. However, this operation is not only time-consuming and labor-intensive, but also results in very uneven grinding.

[0004] In response to the above problems, the present utility model document proposes a bone powder grinder for filling gaps in oral implants. Utility Model Content

[0023] Example:

[0024] Reference Figure 1 and Figure 2 As shown, a bone powder grinder for oral implant filling includes a handheld rod 1. The handheld rod 1 is a cylindrical structure, one end of which is detachably provided with a positioning sleeve 2, and the end surface of the end is provided with a first grinding groove 8; one end of the positioning sleeve 2 is connected to the handheld rod 1, and a grinding head 3 is clamped inside the other end, one end surface of the grinding head 3 is provided with a second grinding groove 9 that matches the first grinding groove 8, and the other end is provided with a connecting rod 5.

[0025] The handheld rod 1 and the connecting rod 5 make it easy for the user to grab the grinder, and the first grinding groove 8 and the second grinding groove 9 cooperate to grind the gum bone particles. The positioning sleeve 2 ensures that the grinding head 3 cooperates with the handheld rod 1, and then ensures that the first grinding groove 8 and the second grinding groove 9 cooperate, and it also makes it easy to collect the ground bone powder.

[0026] The gum bone particles are placed between the grinding head 3 and the handheld rod 1, and the grinding head 3 is rotated by the connecting rod 5 so that the first grinding groove 8 and the second grinding groove 9 cooperate to grind the gum bone particles into powder.

[0027] An outer wall at one end of the handheld rod 1 is provided with an external thread, an inner wall at one end of the positioning sleeve 2 is provided with an internal thread, and the positioning sleeve 2 is threadedly connected to the handheld rod 1.

[0028] The positioning sleeve 2 is connected to the handheld rod 1 through external and internal threads, which improves the stability of the positioning sleeve 2 and also makes it easy to remove the positioning sleeve 2. After the gum bone particles are ground into bone powder, the positioning sleeve 2 is removed to facilitate the collection of bone powder.

[0029] A limiting platform is provided at the end of the handheld rod 1, and one end of the positioning sleeve 2 rests on the limiting platform.

[0030] The positioning sleeve 2 is supported by the limit table to prevent the positioning sleeve 2 from being entirely covered on the handheld rod 1 and unable to position the grinding head 3. In addition, it is inconvenient to collect the bone powder ground by the grinding head 3 and the handheld rod 1. Therefore, one end of the positioning sleeve 2 is threadedly connected to the handheld rod 1 through the limit table to improve the stability of the position of the positioning sleeve 2.

[0031] The side wall of the other end of the handheld stick 1 is provided with anti-slip grooves 7.

[0032] When the grinder is in use, the user needs to hold the handheld rod 1 tightly, and the anti-slip grooves 7 increase the friction between the handheld rod 1 and the user's palm. When the grinding head 3 is rotated to grind the gum bone particles, the handheld rod 1 will not rotate, ensuring normal grinding. If the handheld rod 1 rotates, the grinding head 3 and the handheld rod 1 rotate together, and no grinding effect will be produced on the gum bone particles. Therefore, the anti-slip grooves 7 reduce the force required for the user to grasp the handheld rod 1, thereby reducing the difficulty of using the grinder.

[0033] The outer sleeve of the grinding head 3 is provided with a guide block 4, the grinding head 3 is clamped on the bottom surface of the guide block 4, the connecting rod 5 passes through the guide block 4 and is connected to the grinding head 3, and the guide block 4 matches the inner wall of the positioning sleeve 2.

[0034] The grinding head 3 is positioned by the guide block 4. Since the first grinding groove 8 on the grinding head 3 directly acts on the gum bone particles, the grinding head 3 is made of a titanium alloy with relatively high hardness when in use. In order to reduce production costs, the grinding head 3 is clamped on the guide block 4. The guide block 4 cooperates with the positioning sleeve 2 to improve the stability of the grinding head 3 rotating in the positioning sleeve 2. The material of the guide block 4 can be relatively cheap steel or other hard materials.

[0035] An annular connecting groove 6 is formed on the connecting rod 5 .

[0036] The connecting rod 5 is conveniently connected to the dental handpiece through the connecting groove 6. The dental handpiece drives the connecting rod 5 to rotate, thereby further improving the grinding efficiency, reducing the workload of the user, and reducing the difficulty of operation.

[0037] In actual use, the positioning sleeve 2 is threadedly connected to the end of the handheld rod 1, and then the gum bone particles are placed on the end of the handheld rod 1, and the guide block 4 with the grinding head 3 is placed in the positioning sleeve 2, so that the gum bone particles are stuck between the grinding head 3 and the end face of the handheld rod 1, and between the first grinding groove 8 and the second grinding groove 9, and then the connecting rod 5 is clamped on the dental mobile phone through the connecting groove 6. The user holds the handheld rod 1 with one hand and controls the dental mobile phone with the other hand, so that the dental mobile phone drives the connecting rod 5 to rotate, and then drives the grinding head 3 to rotate, so that the first grinding groove 8 and the second grinding groove 9 grind the gum bone particles, and finally form bone powder, and the bone powder is collected in the positioning sleeve 2. After grinding, take out the guide block 4, pour out the ground particles from the positioning sleeve 2 for collection, and remove the positioning sleeve 2 from the end of the handheld rod 1 after delivery to collect all the remaining bone powder.

[0038] The utility model of the present application has a simple structure, is easy to use and is suitable for promotion.

[0039] The above are only specific embodiments of the present invention, but the scope of protection of the present invention is not limited to them. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this utility model should be included in the scope of protection of the present utility model. The embodiments of the present utility model and the features of the embodiments can be combined with each other unless there is a conflict.
