Description

Technical Field

[0001] This utility model relates to the field of implant technology, and in particular to a micro-threaded implant. Background Technology

[0002] Clinical observations have revealed that implant loosening and fracture are caused by a combination of factors. Among these, inadequate implant design is particularly critical. Many implants have low neck strength, making them unable to withstand the forces of biting, thus inherently posing a risk. Simultaneously, during implant surgery, the surgical environment allows bacteria and microorganisms to easily enter the cortical bone. Once invading, they significantly interfere with the osseointegration process, causing numerous difficulties and even leading to failure. If osseointegration cannot be achieved successfully, the implant loses its stable foundation, inevitably leading to loosening, and in severe cases, fracture. This causes considerable inconvenience and pain for the patient and negatively impacts the outcome of the implant surgery. Therefore, improvements are needed to address these issues. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a micro-threaded implant.

[0005] Preferably, the bottom surface of the internal hexagonal slot is provided with a mounting groove, and the inner wall of the mounting groove is provided with a fine thread groove.

[0006] Preferably, the lower end of the cylinder is placed inside a rubber sleeve, a retaining ring is fixedly connected to the inner wall of the rubber sleeve, and the bottom surface of the cylinder abuts against the retaining ring.

[0007] Preferably, a limiting ring is fixed to the outer side of the lower end of the cylinder, and a limiting groove that mates with the limiting ring is opened on the inner wall of the rubber sleeve. The limiting groove is placed on the upper end of the retaining ring, the limiting ring is placed in the limiting groove, and the cylinder and the rubber sleeve are rotatably connected.

[0008] Preferably, the sleeve is filled with hydroxyapatite material, and the outer side of the sleeve has multiple equidistant discharge ports.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: In this utility model, the cooperation between the rubber sleeve and the cylinder facilitates the cylinder to squeeze the rubber sleeve, thereby squeezing out the hydroxyapatite material inside the rubber sleeve, which improves the efficiency of the fusion between the cylinder and the new tissue; the cooperation between the rubber sleeve and the hydroxyapatite facilitates the filling of the gap around the cylinder, which improves the fusion effect between the cylinder and the new tissue; the cooperation between the straight thread and the fine thread groove facilitates better installation of the tooth body, which improves the effect of tooth installation.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Example: See Figure 1-4This utility model discloses a micro-threaded implant, comprising a cylinder 1, a rubber sleeve 2 at the lower end of the cylinder 1, and a straight thread 3 on the outer side of the lower end of the cylinder 1, and an internal hexagonal groove 4 on the top surface; the cylinder 1 facilitates connection to the tooth body; the rubber sleeve 2 facilitates storage of hydroxyapatite 9 material; the straight thread 3 facilitates the installation of the cylinder 1, and the internal hexagonal groove 4 facilitates control of the rotation of the cylinder 1; the inner bottom surface of the internal hexagonal groove 4 has an installation groove 5, and the inner wall of the installation groove 5 has a fine thread groove 6; the installation groove 5 and the fine thread groove 6 facilitate the installation of the tooth body onto the cylinder 1; the lower end of the cylinder 1 is placed inside the rubber sleeve 2, and a retaining ring 7 is fixedly connected to the inner wall of the rubber sleeve 2, and the cylinder 1... The bottom surface of column 1 abuts against retaining ring 7; retaining ring 7 facilitates the compression of rubber sleeve 2 by column 1; a limiting ring 8 is fixed to the outer side of the lower end of column 1, and a limiting groove that mates with limiting ring 8 is opened on the inner wall of rubber sleeve 2. The limiting groove is placed on the upper end of retaining ring 7, and limiting ring 8 is placed in the limiting groove. Column 1 and rubber sleeve 2 are rotatably connected; limiting ring 8 facilitates the rotatable connection between column 1 and rubber sleeve 2; hydroxyapatite 9 material is filled inside rubber sleeve 2, and multiple equidistant discharge ports 10 are opened on the outer side of rubber sleeve 2; hydroxyapatite 9 material facilitates the connection between column 1 and newly formed tissue; discharge ports 10 facilitate the extrusion of hydroxyapatite 9 material when rubber sleeve 2 is compressed.

[0018] Working principle: When using this invention, firstly, an installation hole is made at the site where the implant is needed. Then, a threaded groove with a matching straight thread 3 is made on the upper end of the inner wall of the installation hole. The remaining material from the opening and groove in the installation hole is then sucked out. Next, the cylinder 1 and the rubber sleeve 2 are inserted into the installation hole. Because the diameter of the rubber sleeve 2 is larger than that of the cylinder 1, and because the rubber sleeve 2 is flexible, the outer wall of the rubber sleeve 2 abuts against the inner wall of the installation hole. Then, the cylinder 1 is controlled to rotate through the internal hexagonal groove 4. Through the cooperation of the straight thread 3 and the threaded groove, when the cylinder 1 rotates, it controls the cylinder 1 to descend, thereby pushing the rubber sleeve 2 to descend. When the rubber sleeve 2 abuts against the inner bottom surface of the installation hole, the cylinder 1 is rotated, thereby squeezing the rubber sleeve 2, and thus pushing the hydroxyapatite 9 material inside the rubber sleeve 2 out through the discharge port 10, thereby filling the gap inside the installation hole, and using the cylinder 1 to better integrate the new tissue. After the cylinder 1 is installed, the tooth body is installed through the installation groove 5 and the fine thread groove 6.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
