Description

Technical Field

[0001] This utility model relates to the field of dental technology, and more specifically, to a scanning rod. Background Technology

[0002] In the digital design phase of dental implant restoration, the scanning probe plays a crucial role. Currently, digital intraoral scanning is a key technology for acquiring the three-dimensional morphology of intraoral tissues. By connecting the scanning probe to the implant or implant abutment, and utilizing optical scanning principles, depth reconstruction is completed in real time, acquiring local point cloud data, and then generating three-dimensional mesh data to calculate the exact three-dimensional position of the implant.

[0003] However, in the use of existing technology, the scanning rod is usually made of metal, which requires regular replacement and has a high cost. Moreover, if disinfection is not thorough after the first use, it can easily cause cross-infection. In order to reduce costs and prevent cross-infection, a new scanning rod has been proposed. Utility Model Content

[0004] The purpose of this invention is to address the problems of current scanning bars, which are usually made of metal, require regular replacement, have high operating costs, and are prone to cross-infection if not thoroughly disinfected after the first use. This invention aims to reduce costs and prevent cross-infection.

[0005] To achieve the aforementioned objectives and address the aforementioned problems, this utility model provides a scanning rod comprising a device body. Multiple reinforcing columns and multiple reinforcing rings are fixedly connected internally to the device body. The outer surfaces of the multiple reinforcing rings are fixedly connected to the surfaces of the multiple reinforcing columns. A first inner groove is formed inside the device body. An inclined groove is formed at the bottom end of the device body near the first inner groove. A support platform is formed at the end of the device body away from the first inner groove. An internal thread is provided inside the support platform near the inclined groove. A support platform is formed on the outer surface of the device body. A nameplate is fixedly connected to the surface of the support platform. A guide platform is formed on the outer surface of the device body at a position perpendicular to the support platform.

[0006] As a preferred technical solution of this application, a screw head is provided inside the device body, and the bottom inclined surface of the screw head is in contact with the surface of the inclined groove.

[0007] As a preferred technical solution of this application, a stud is fixedly connected to the bottom end of the screw head, and the internal thread of the internal thread is adapted to the thread on the outer surface of the stud.

[0008] As a preferred technical solution of this application, an implant is provided on the outer surface of the device body, the interior of the implant is threadedly connected to the outer surface of the stud, and the thread inside the implant is adapted to the thread on the outer surface of the stud.

[0009] As a preferred technical solution of this application, a hexagonal fixing head is fixedly connected to the bottom end of the device body, and a locking block is fixedly connected to the outer surface of the hexagonal fixing head.

[0010] As a preferred technical solution of this application, the implant has a slot inside, and the inside of the slot is in contact with the outer surface of the card block.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. In the solution of this application: when in use, medical-grade PEEK is used to make reinforcing columns and reinforcing rings, and then additive printing technology is used to quickly print and manufacture the components. The quadrilateral formed between the reinforcing rings and reinforcing columns is used to reinforce the entire device, giving the device higher strength. This achieves accurate, safe, efficient, and low-cost manufacturing of the scanning rod, greatly reducing costs and ensuring safety in use.

[0013] 2. In the scheme of this application: During use, firstly, the screw head and stud are placed into the first inner groove and slid into the bottom of the first inner groove. Then, the screw head is rotated using an external tool, causing the screw head to rotate and engage with the internal thread until the bottom end of the stud is rotated to be flush with the lower surface of the hexagonal fixing head. Then, the hexagonal fixing head is placed into the implant, and the positions of the slot and the locking block are aligned. Then, the screw head is rotated using an external tool, causing the screw head and stud to rotate and move downwards. The stud engages with the internal thread of the implant, limiting and fixing the device body, which prevents the stud and screw head from accidentally falling into the patient's mouth during installation and affecting the patient's safety.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0022] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0023] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0024] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0025] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5A scanning rod includes a device body 1, with multiple reinforcing columns 3 fixedly connected internally. These reinforcing columns 3 provide vertical reinforcement to the device. The surface of the device body 1 is made of medical-grade resin material, manufactured using additive printing technology for rapid printing, achieving precise, safe, efficient, and low-cost operation. Multiple reinforcing rings 8 are also fixedly connected internally to the device body 1. These reinforcing rings 8 reinforce the circumference of the device, and the quadrilateral formed between the reinforcing rings 8 and the reinforcing columns 3 further strengthens the entire device, increasing its strength and ensuring safe operation. The reinforcing columns 3 and reinforcing rings 8 are made of medical-grade PEEK. The outer surface is fixedly connected to the surfaces of multiple reinforcing columns 3. The inner surface of the device body 1 is provided with a first inner groove 4, which serves to place and guide subsequent components. The bottom of the device body 1 near the first inner groove 4 is provided with a sloping groove 15. The end of the device body 1 away from the first inner groove 4 is provided with a support platform 6. The support platform 6 is provided with an internal thread 13 near the sloping groove 15. The outer surface of the device body 1 is provided with a support platform 6. A nameplate 5 is fixedly connected to the surface of the support platform 6. The nameplate 5 serves to display component information. The outer surface of the device body 1 is provided with a guide platform 14 perpendicular to the support platform 6. The guide platform 14 helps the staff to quickly understand the installation direction of the device.

[0026] Furthermore, such as Figure 2 , Figure 5 As shown, a screw head 7 is provided inside the device body 1. The bottom inclined surface of the screw head 7 contacts the surface of the inclined groove 15. The contact between the inclined groove 15 and the bottom inclined surface of the screw head 7 makes the screw head 7 more firmly fixed to the device body 1.

[0027] Furthermore, such as Figure 2 , Figure 5 As shown, a stud 12 is fixedly connected to the bottom end of the screw head 7. The internal thread 13 is adapted to the thread on the outer surface of the stud 12. The stud 12 and the internal thread 13 engage with each other, so that when the device body 1 is not installed into the patient's mouth, the stud 12 and the screw head 7 are limited inside the device body 1, preventing the stud 12 and the screw head 7 from accidentally falling into the patient's mouth and causing danger.

[0028] Furthermore, such as Figure 2 , Figure 5 As shown, an implant 2 is provided on the outer surface of the device body 1. The interior of the implant 2 is threadedly connected to the outer surface of the stud 12, and the thread inside the implant 2 is adapted to the thread on the outer surface of the stud 12. The stud 12 and the implant 2 engage to compress and fix the device body 1.

[0029] Furthermore, such as Figure 2 , Figure 5 As shown, a hexagonal fixing head 11 is fixedly connected to the bottom of the device body 1, and a locking block 10 is fixedly connected to the outer surface of the hexagonal fixing head 11. The hexagonal fixing head 11 serves to limit and fix the position of the locking block 10.

[0030] Furthermore, such as Figure 2 , Figure 5 As shown, the implant 2 has a slot 9 inside, and the inside of the slot 9 is in contact with the outer surface of the block 10. The slot 9 serves to limit the position of the block 10.

[0031] The scanning bar provided by this utility model is used as follows: During use, the scanning bar is manufactured using medical-grade resin material through additive printing technology. The device body 1 is reinforced internally by reinforcing posts 3 and reinforcing rings 8 made of medical-grade PEEK. The implant 2 is then fixed in the patient's oral cavity. First, the screw head 7 and stud 12 are placed into the first inner groove 4, and the screw head 7 and stud 12 are slid into the bottom of the first inner groove 4. Then, the screw head 7 is rotated using an external tool, causing the screw head 7 to drive the stud 12 to rotate, allowing the stud 12 to engage with the internal thread 13 until the bottom end of the stud 12 is flush with the lower surface of the hexagonal fixing head 11. Then, the device body 1 is initially identified through the guide platform 14. Observe the position of the bottom locking block 10, then observe the position of the internal locking groove 9 of the implant 2. Insert the hexagonal fixing head 11 into the implant 2, and align the locking groove 9 with the locking block 10. Use the locking block 10 and the locking groove 9 to limit the installation angle of the device body 1, so that the hexagonal fixing head 11 fits tightly with the inside of the implant 2. Then, use an external tool to rotate the screw head 7, so that the screw head 7 and the stud 12 rotate and move downward. The stud 12 engages with the internal thread of the implant 2 to limit and fix the device body 1. At the same time, the stud 12 gradually disengages from the internal thread 13. Use the bottom bevel of the screw head 7 to press the inclined groove 15 to ensure stable contact between the implant 2 and the device body 1.
