Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to an oral implant guide plate fixing device. Background Art

[0002] Oral implantation refers to the process of implanting artificial tooth roots made of biological or non-biological materials into alveolar bone. Digital implantation is the cutting-edge technology of oral implantation. It relies on full-mouth CT scan to measure the height, width, and tightness of the alveolar bone at the toothless site and calculate the relevant data. Doctors analyze these three-dimensional data to determine the best position for implantation, including angle and depth, and then design implantation guides to accurately control the position of the implant to ensure the success of the operation and subsequent restoration.

[0003] The currently used fixing device is to directly install a retractable supporting device on the implant guide to support the oral cavity. However, in actual use, the implant guide cannot be reused because each person's missing teeth position and alveolar bone height and width are different. After use, the fixing device is difficult to remove, disinfect and reuse from the implant guide, and it is costly to abandon it directly. In this regard, an oral implant guide fixing device that can be easily removed from the implant guide is provided. Utility Model Content

[0004] The purpose of the utility model is to solve the problems in the above-mentioned background technology and provide an oral implant guide plate fixing device.

DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the present utility model.

[0020] like Figure 1-4 As shown, an oral implant guide fixing device comprises an implant guide 1, which is made of relatively hard medical rubber or plastic. The upper surfaces of the two ends of the implant guide 1 are covered with a cover plate 2, and a card slot 3 is provided on the upper surface of the implant guide 1 in the contact middle part of the cover plate 2. A card block 4 is fixedly connected to the lower surface of the cover plate 2, and the card block 4 is vertically inserted into the inside of the card slot 3. A fixed block 5 is fixedly connected to the upper surface of the cover plate 2, and a rotating block 6 is rotatably connected to the inside of the fixed block 5. A threaded sleeve 7 is fixedly connected to the top of the rotating block 6. The opening of the threaded sleeve 7 faces upward and is internally threadedly connected to a screw 8. The top of the screw 8 is fixedly connected to a limiting block 9. A connecting sleeve 10 is sleeved on the outer surface of the limiting block 9 and is rotatably connected. Another rotating block 6 and The fixing block 5, the top of the upper fixing block 5 is fixedly connected to the lower surface of the pressing plate 11, and the manufactured implant guide 1 is connected to the cover plate 2, so that the card block 4 is inserted into the card slot 3 and installed on the tooth, and then the screw 8 is rotated, and the screw 8 is rotated and extended upward to open the mouth, so that the cover plate 2 and the implant guide 1 are squeezed into the lower gum, and the pressing plate 11 squeezes the upper gum to achieve oral support. Due to the backlog, the card block 4 cannot be separated from the card slot 3, thereby ensuring the stability of the connection between the implant guide 1 and the cover plate 2. After the operation is completed, the screw 8 is rotated in the opposite direction to retract it into the threaded sleeve 7, and then the fixing device is taken out and separated from the implant guide 1, so as to facilitate the disinfection of the device. When used next time, the card block 4 can be inserted into the card slot 3 of the next implant guide 1.

[0021] like Figure 1 As shown, in some embodiments, the inner surface of the pressure plate 11 is fixedly connected with an anti-slip layer 12. Specifically, the installed anti-slip layer 12 prevents the pressure plate 11 from slipping on the tooth surface when squeezing the upper teeth, thereby preventing the pressure plate 11 from slipping and falling due to oral movement and the like, causing the oral cavity to lose support.

[0022] like Figure 3As shown, in some embodiments, the side wall portion of the cover plate 2 close to the inner side of the oral cavity is cut off and separated from the main body, a threaded hollow tube 13 is fixedly connected to a place on the upper surface of the main body of the cover plate 2, and a sliding block 14 is fixedly connected to the top of the cut side wall of the cover plate 2. The inside of the threaded hollow tube 13 and the sliding block 14 penetrates and is threadedly connected with a screw 2 15 from the side of the sliding block 14 close to the oral cavity. Specifically, when connecting the cover plate 2 and the planting guide 1, the divided side wall of the cover plate 2 is first unfolded, and then the screw 2 15 is rotated to squeeze the screw 2 15 toward the planting guide 1, so that the planting guides 1 of different sizes can be squeezed and fixed sideways, so that the connection between the cover plate 2 and the planting guide 1 is more stable and not easy to shake. In actual use, the position of the card slot 3 should be changed to the same distance as the outer surface of the planting guide 1, instead of the middle, so that the card block 4 can be inserted into the card slot 3 and the side faces fit.

[0023] like Figure 3 As shown, in some embodiments, a hexagonal hole 16 is opened inwardly on the screw head surface of the second screw 15. Specifically, the hexagonal hole 16 allows the doctor to operate it with a wrench or other tool to avoid the second screw 15 being too small and difficult to operate.

[0024] like Figure 1 As shown, in some embodiments, the bottom length of the pressing plate 11 is extended toward one side of the cut side wall of the cover plate 2. Specifically, the extended portion of the pressing plate 11 is used to make it interference fit with a larger tooth to avoid it not being able to get stuck into the tooth and affecting its use or being pressed too tightly and causing discomfort to the patient. Directly making it larger instead of cutting and installing screws 15 like the cover plate 2 can reduce unnecessary operations.

[0025] like Figure 1 , 4 As shown, in some embodiments, the outer surface of the planting guide 1 is symmetrically arranged and fixedly connected with an extension tube 17, and an opening plate 18 is provided on the outer side of the planting guide 1. The opening plate 18 is fixedly connected with a connecting rod 19 close to the surface of the planting guide 1, and the connecting rod 19 is inserted into the interior of the extension tube 17. Specifically, the opening plate 18 can be fixed by inserting the connecting rod 19 into the extension tube 17, and the opening plate 18 can be used to open the lips partly to facilitate the operation. After the operation is completed, it can be pulled out and disinfected and used together with the fixing device.

[0026] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
