Description

Technical Field

[0001] This application relates to the field of dental implant technology, and in particular to a dental implant external connection force-applying screwdriver. Background Technology

[0002] Dental implantation refers to a method of restoring missing teeth by using a substructure implanted into the bone tissue to support and retain the superstructure. It consists of two parts: the supporting implant and the superstructure dental prosthesis. The implant (generally resembling a tooth root) is made of artificial materials (such as metal or ceramic) and surgically implanted into the bone tissue (usually the upper or lower jaw) to obtain firm retention support. It is then connected to the superstructure dental prosthesis using special devices and methods.

[0003] In dental implantology, the external connecting composite and screwdriver used for edentulous jaw restoration require a dedicated one-to-one ratchet wrench to apply a certain torque value, so that they are tightly connected to the internal threads of the corresponding implant to achieve a good retention effect and support the occlusal force of the edentulous jaw bridge.

[0004] Currently, the mainstream and common ratchet wrenches used in implant restorations have various screwdriver-like connection points with adjustable screwdrivers, including small square, large square, hexagonal, round toothed, and Torx-shaped. The most commonly used are small square, large square, and round toothed. Existing adjustable screwdrivers generally correspond to one connection point shape, requiring multiple adjustable screwdrivers and ratchet wrenches of different shapes for implant dentists or prosthodontists to use. This results in high equipment costs and increased instrument sterilization workload, thus requiring improvement. Utility Model Content

[0005] To increase the applicability of screwdrivers, this application provides a force-applying screwdriver for external connection of dental implants.

[0006] This application provides a dental implant external connection force-applying screwdriver with the following technical solution:

[0007] A dental implant external connection force-applying screwdriver includes a screwdriver body, on which a small square block, a large square block, and a circular toothed block are coaxially arranged in sequence. The small square block is located at one end of the screwdriver body, and the side length of the small square block is smaller than the side length of the large square block. The side length of the large square block is smaller than or equal to the side length of the square inscribed in the circular toothed block. The circular toothed block has grooves on its circumference, and the grooves are spaced apart along the circumferential direction.

[0008] By adopting the above technical solution, the screwdriver is optimized to have small square, large square, and round teeth, eliminating the need to prepare multiple types of ratchet wrenches for the corresponding connection parts. During dental implantation, the screwdriver is used to tighten the implant into the drilled hole in the alveolar bone.

[0009] This approach can, to some extent, prevent errors made by novice implant surgeons or nurses during clinical procedures, and also reduce the workload of instrument sterilization in clinics. Furthermore, it alleviates the pressure on clinics regarding fixed asset investment in implant tools, allowing them to allocate funds to more valuable and effective tools.

[0010] Preferably, the four edges of the small square are rounded.

[0011] By adopting the above technical solutions, rounded corners can enhance the overall aesthetics of the small square and reduce its sharpness.

[0012] Preferably, the four edges of the large square block are rounded.

[0013] By adopting the above technical solutions, rounded corners can enhance the overall aesthetics of the large square and reduce its sharpness.

[0014] Preferably, the outer side wall of the screwdriver body is provided with a plurality of reinforcing strips, each reinforcing strip being spaced apart along the circumferential direction and located on the side of the circular tooth block away from the large square block.

[0015] By adopting the above technical solutions, the reinforcing strip can increase the breakage resistance of the screwdriver body and extend its service life.

[0016] Preferably, a limiting protrusion is provided on the side of the circular toothed block away from the large square block, and the outer diameter of the limiting protrusion is larger than the diameter of the circular toothed block.

[0017] By adopting the above technical solution, the limiting protrusion ring can play a limiting role, so that the wrench's jaws abut against the limiting protrusion ring.

[0018] Preferably, the end of the screwdriver body away from the small square block is provided with a sleeve, and the sleeve has an internal hexagonal hole.

[0019] By adopting the above technical solution, the internal hexagonal hole can better position and tighten the implant.

[0020] Preferably, the outer surface of the screwdriver body is coated with an anti-stick coating.

[0021] By adopting the above technical solutions, it is possible to address the risk of cross-infection due to the unique nature of medical devices' contact with living organisms, where bacteria, viruses, and other microorganisms often adhere to the device surface. Medical device anti-stick coatings are special coatings that can adhere to the surface of medical devices, possessing antibacterial, antiviral, and anti-contamination functions. These coatings effectively prevent the adhesion and reproduction of microorganisms, thereby reducing the risk of cross-infection.

[0022] Preferably, the small square block is located in the plane of the large square block, and the large square block is located in the plane of the circular toothed block.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] (1) By setting small square blocks, large square blocks and round toothed blocks in a stepped manner, one item can be used for multiple purposes, reducing the workload of the clinic instrument disinfection process and increasing the applicability of screwdrivers.

[0025] (2) By setting an anti-stick coating, the anti-stick coating has antibacterial, antiviral and anti-pollution functions, which can effectively prevent microorganisms from attaching and multiplying on the screwdriver body.

[0026] (3) By setting up reinforcing strips, the reinforcing strips can increase the fracture resistance of the screwdriver body and extend the service life of the entire power screwdriver. Attached Figure Description

For example, they can refer to a fixed connection; a detachable connection; an integral part; or a mechanical connection. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application according to the specific circumstances.

[0035] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Without conflict, those skilled in the art can combine and integrate the different embodiments or examples shown in this application, as well as the features of those embodiments or examples.

[0036] This application discloses a dental implant external connection force-applied screwdriver. (Refer to...) Figure 1 and Figure 2 The power screwdriver includes a screwdriver body 1, on which a small square block 2, a large square block 3, and a circular toothed block 4 are sequentially arranged. The large square block 3 is located between the small square block 2 and the circular toothed block 4. The small square block 2, the large square block 3, and the circular toothed block 4 are coaxially arranged, with the small square block 2 located at one end of the screwdriver body 1. The side length of the small square block 2 is smaller than the side length of the large square block 3, and the small square block 2 is located in the plane containing the large square block 3. The side length of the large square block 3 is less than or equal to the side length of the square inscribed in the circular toothed block 4. The circular toothed block 4 is cylindrical, and grooves 5 are formed on its circumference, with each groove 5 spaced apart along the circumference.

[0037] In this embodiment, the small square block 2 has a cross-section of 3.97mm, corresponding to the jaw of the small square wrench (4mm*4mm). The large square block 3 has a cross-section of 4.8mm, corresponding to the jaw of the large square wrench (5mm*5mm). The circular toothed block 4 has a cross-section diameter of 6.95mm, corresponding to the jaw of the circular wrench (7mm diameter). The length of the jaw is designed to be smaller than the inner diameter of the wrench, mainly for tolerance considerations, to avoid the jaw being too tight, which would hinder the wrench's positioning and disengagement on the power screwdriver.

[0038] Specifically, the four corners of the small square block 2 are rounded, and the four corners of the large square block 3 are also rounded. Rounding enhances the overall aesthetics of both blocks and softens their sharp edges. A limiting ring 6 is integrally connected to the side of the circular toothed block 4 furthest from the large square block 3; the outer diameter of the limiting ring 6 is larger than the diameter of the circular toothed block 4. When the circular wrench is engaged with the circular toothed block 4, the limiting ring 6 acts as a limit, ensuring the wrench's jaws rest against it. A sleeve 7 is provided at the end of the screwdriver body 1 furthest from the small square block 2. The sleeve 7 has an internal hexagonal hole 8, used for positioning and tightening the implant. In this embodiment, the outer surface of the screwdriver body 1 is coated with an anti-stick coating. This anti-stick coating is a special coating that can adhere to the surface of medical devices and has antibacterial, antiviral, and anti-contamination functions, effectively preventing the attachment and reproduction of microorganisms on the screwdriver body 1, thereby reducing the risk of cross-infection.

[0039] In addition, in some embodiments, please refer to Figure 3 Several reinforcing strips 9 are fixedly connected to the outer wall of the screwdriver body 1. Each reinforcing strip 9 is distributed at intervals along the circumference and is located on the side of the circular toothed block 4 away from the large square block 3. Each reinforcing strip 9 extends along the central axis of the screwdriver body 1. The reinforcing strips 9 can increase the breakage resistance of the screwdriver body 1 and extend its service life.

[0040] The implementation principle of the external connection screwdriver for dental implants in this application embodiment is as follows: the screwdriver has small square, large square, and round tooth shapes, so that multiple types of ratchet wrenches are no longer needed for the connection parts. During dental implantation, the screwdriver is used to tighten the implant into the drilled hole in the alveolar bone.

[0041] The optimized design of the screwdriver can, to some extent, prevent errors by novice implant surgeons or nurses during clinical procedures, and also reduce the workload of instrument sterilization in clinics. Furthermore, it alleviates the pressure on clinics to invest in fixed assets related to implant tools, allowing them to allocate funds to more valuable tools.

[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
