Description

Technical Field

[0001] This utility model relates to the field of dental implant technology, and in particular to a bone powder scraper for dental implantation. Background Technology

[0002] During dental implant surgery, a positioning hole is drilled on a pressure plate, and then the implant is inserted into the positioning hole. Since the diameter of the positioning hole is larger than the diameter of the implant, in order to ensure the stability of the implanted tooth, bone fragments are taken from the patient's mouth and used to fill the area around the implant in order to improve the healing of the alveolar bone around the implant. For extremely small gaps, the removed bone fragments are ground into powder and used to fill the gaps, so that the implant will not move in the positioning hole and improve the stability of the implant.

[0003] If the amount of bone powder removed during bone harvesting is insufficient, and the doctor uses the bone harvester again, the amount removed will be excessive, resulting in waste. Moreover, for the patient, this not only prolongs the treatment time but also increases unnecessary trauma.

[0004] To address the aforementioned problems, this utility model document proposes a bone powder scraper for dental implantation. Utility Model Content

[0005] This invention provides a bone powder scraper for dental implantation, which can directly scrape bone powder from the bone harvesting site according to the required amount, shortening the operation time and reducing unnecessary trauma to the patient.

[0006] This utility model provides the following technical solution:

[0007] A bone powder scraper for dental implantation includes a handle, one end of which is provided with a connecting component, one end of which is fixedly connected to the handle, and the other end of which is provided with a blade assembly. A bone collector is fitted onto the connecting component, a first gap for collecting bone powder is left between the bone collector and the connecting component, and a second gap is left between the end face of the bone collector and the blade assembly.

[0008] Furthermore, the blade assembly includes a scraper and a connecting screw. The scraper has a frustum-shaped structure, with the connecting screw perpendicularly disposed on the end face with a larger diameter, and the outer edge of that end is a cutting edge.

[0009] Furthermore, the end face of the scraper with the smaller diameter is provided with an internal hexagonal hole.

[0010] Furthermore, the connecting component includes a positioning block, which is a cylindrical structure with one end fixed to the end of the handle and a connecting block on the other end. The connecting block is a cylindrical structure with external threads on its outer side wall. One end of the connecting block is connected to the positioning block, and the other end is provided with a connecting rod. One end of the connecting rod is connected to the connecting block, and the other end is provided with a threaded hole that mates with the connecting screw. A first gap is left between the connecting rod and the inner side wall of the bone collector.

[0031] Example:

[0032] Reference Figures 1 to 9 As shown, a bone powder scraper for dental implantation includes a handle 1. One end of the handle 1 is provided with a connecting component 4, one end of the connecting component 4 is fixedly connected to the handle 1, and the other end is provided with a blade assembly 3. A bone collector 2 is sleeved on the connecting component 4. A first gap 5 for collecting bone powder is left between the bone collector 2 and the connecting component 4, and a second gap 6 is left between the end face of the bone collector 2 and the blade assembly 3.

[0033] The blade assembly 3 is used to scrape bone meal. The connecting assembly 4 connects the blade assembly 3 to the handle 1. The first gap 5 between the connecting assembly 4 and the bone collector 2 is used to collect the bone meal scraped off by the blade assembly 3. The second gap 6 between the end face of the bone collector 2 and the blade assembly 3 allows the bone meal to enter the first gap 5 through the second gap 6.

[0034] The physician holds the handle 1 and scrapes bone powder from the bone harvesting site using the blade assembly 3. The scraped bone powder enters the first gap 5 through the second gap 6 for collection. The entire operation is simple and convenient. Moreover, the physician can scrape bone powder according to actual needs without causing large-area trauma to the patient, which facilitates the patient's healing and shortens the operation time. It is highly flexible.

[0035] The blade assembly 3 includes a scraper 301 and a connecting screw 302. The scraper 301 has a frustum-shaped structure, and the connecting screw 302 is perpendicularly arranged on the end face with a larger diameter, and the outer edge of this end is a cutting edge.

[0036] The bone is scraped by the outer edge of the scraper 301, which has a frustum-shaped structure and an arc-shaped contact surface with the bone. This facilitates scraping, improves scraping efficiency, and allows for better swinging motions. Combined with wrist rotation, this makes scraping easier and less strenuous, adaptable to changes in the bone surface, and provides greater operational flexibility.

[0037] The scraper 301 has an internal hexagonal hole 303 on the end face of the smaller diameter end.

[0038] The internal hexagonal hole 303 facilitates the installation of the scraper 301 onto the connecting assembly 4 using an internal hexagonal wrench. Since the scraper 301 has a frustum-shaped structure and very sharp edges, it is not easy to tighten by hand, which may cause the scraper 301 to loosen and affect the normal operation of scraping the bone. In addition, it may also cut the fingers. The internal hexagonal hole 303 improves the safety of installation.

[0039] The connecting component 4 includes a positioning block 401, which is a cylindrical structure. One end of the positioning block 401 is fixed to the end of the handle 1, and the other end is provided with a connecting block 402. The connecting block 402 is a cylindrical structure with external threads on its outer side wall. One end of the connecting block 402 is connected to the positioning block 401, and the other end is provided with a connecting rod 403. One end of the connecting rod 403 is connected to the connecting block 402, and the other end is provided with a threaded hole 404 that mates with the connecting screw 302. A first gap 5 is left between the connecting rod 403 and the inner side wall of the bone collector 2.

[0040] The bone collector 2 is a ring-shaped cylindrical structure. Its inner side wall is provided with an annular limiting platform 202 corresponding to the position of the connecting block 402. The inner wall of the limiting platform 202 is provided with an internal thread that matches the external thread of the side wall of the connecting block 402. One end of the bone collector 2 is provided with a positioning groove 201 that matches the positioning block 401. The inner side wall of the other end is left with a first gap 5 between it and the connecting rod 403. The first gap 5 and one side of the limiting platform 202 form a bone powder storage cavity.

[0041] The positioning block 401 and the positioning groove 201 are used to position the bone collector 2 so that the bone collector 2 will not shake. The connecting block 402 and the limiting platform 202 are used to fix the bone collector 2 on the connecting rod 403. The connecting rod 403 is used to install the scraper 301. The connecting block 402 and the limiting platform 202 are threadedly connected. The width of the second gap 6 between the bone collector 2 and the scraper 301 can be adjusted by rotating the bone collector 2, so that the bone powder can enter the storage cavity through the second gap 6.

[0042] The outer side wall of the bone retractor 2 is evenly provided with multiple clamping planes 203 that facilitate clamping and rotating the bone retractor 2.

[0043] Since the bone retractor 2 has a ring-shaped cylindrical structure and a relatively smooth surface, the clamping plane 203 makes it easy for the user to rotate the bone retractor 2 and adjust the width of the second gap 6 between the bone retractor 2 and the scraper 301.

[0044] The surface of the handle 1 is provided with anti-slip texture 7.

[0045] The anti-slip texture 7 increases the friction of the handle 1, ensuring that the physician can grip the handle 1 firmly. Since the physician needs to exert a lot of force when scraping bone powder with the scraper 301, if the handle 1 is not gripped firmly, the control of the scraper 301 will not be accurate, which may cause accidental injury to the patient. The anti-slip texture 7 improves the physician's control over the scraper, improves the safety of the scraper's practicality, and thus improves the patient's safety.

[0046] During assembly, the physician places one end of the positioning groove 201 of the bone collector 2 onto the positioning block 401, and simultaneously rotates the bone collector 2 so that the internal thread on the limiting platform 202 engages with the external thread on the connecting block 402, thereby installing the bone collector 2 onto the connecting assembly 4. Then, the blade assembly 3 is secured to the hexagonal wrench through the internal hexagonal hole 303. The connecting screw 302 is then aligned with the threaded hole 404 at the end of the connecting rod 403, and the hexagonal wrench is rotated to connect the blade assembly 3 to the connecting rod 403. During use, the physician grips the handle 1 firmly, aligns the edge of the scraper 301 with the bone harvesting position, and moves the scraper 301 up and down to scrape off bone powder. The scraped bone powder enters the collection cavity through the second gap 6 for collection.

[0047] When scraping bone powder, doctors can scrape off an appropriate amount of bone powder according to the needs of the patient. The operation is flexible and will not increase the patient's wound, which facilitates wound healing and shortens the bone collection time.

[0048] In practical use, the handle 1 and the connecting component 4 are integrally molded, which improves the overall structural strength of the bone meal scraper.

[0049] The handle 1 is connected to one end of the scraper 301 at an angle of 130° to 150° with the other end. This facilitates the entry of bone powder into the receiving cavity and makes it easier for the doctor to control the direction of the scraper 301.

[0050] The maximum diameter of the scraper 301 is 0.5 to 1 mm larger than the diameter of the bone collector 2 to avoid the bone collector 2 affecting the scraper 301's bone scraping function.

[0051] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. In the absence of conflict, the embodiments and features in the embodiments of this utility model can be combined with each other. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
