Parallel planting aid

Abstract

This invention relates to the field of oral prosthetics technology and provides a parallel implant assist device, including a first assist device arm, a first rotating shaft internally connected to the first assist device arm, a second assist device arm internally connected to the outer wall of the first rotating shaft, a first hole, a second hole, and a third hole inside the first assist device arm. The invention features a design where the upper ends of the first and second assist device arms are 8 cm from the first rotating shaft, while the lower ends are 4 cm from the first rotating shaft. The intersection point is longer at the top and shorter at the bottom, allowing for adaptation to different oral openings. The shorter lower branch can extend into the patient's narrow oral cavity, adapting to the natural opening width of the mouth. This prevents the arm from obstructing the soft tissues of the upper and lower lips or cheeks due to excessive length, eliminating the need for repeated traction of the corners of the mouth during surgery and significantly improving the adaptability of the intraoral operating space.

Description

Technical Field

[0001] This invention relates to the field of oral prosthetics, and in particular to parallel implant aids. Background Technology

[0002] Dental implant technology is currently the mainstream technology in the field of oral restoration, widely used in the restoration treatment of single tooth loss, multiple tooth loss, and complete tooth loss. In scenarios involving multiple implant restorations, crown restorations, and edentulous jaw implant restorations, the parallelism between adjacent and multiple implants is the core key to ensuring the effectiveness of the implant restoration and extending the lifespan of the implants. Currently, the auxiliary methods for parallel implant placement in clinical implant surgery are relatively limited. Traditional implant operation mainly relies on the clinical experience of medical staff for visual positioning and manual control of the implant drilling angle. This method is highly dependent on the operator's skill level, highly subjective, and has extremely low precision. In scenarios involving multiple consecutive tooth loss and large-area implantation in edentulous jaws, the complex alveolar bone anatomy and limited field of vision make it easy for problems such as implant angle deviation and axis non-parallelism to occur. This directly leads to poor fit of the restoration and uneven occlusal force, significantly increasing the risk of implant failure. Therefore, parallel implant assistive devices are needed. Existing parallel implant assist devices cannot match the required size of implant holes according to actual implant needs, resulting in poor adaptability of single-size holes and affecting the efficiency of actual dental implantation. Summary of the Invention

[0003] The purpose of this invention is to provide a parallel planting aid to solve the problem that existing parallel planting aids cannot match the required size of planting holes according to actual planting needs.

[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a parallel planting aid, including a first aid arm; The first auxiliary arm is movably connected to a first rotating shaft inside, and the outer wall of the first rotating shaft is movably connected to a second auxiliary arm. The first auxiliary arm has a first hole, a second hole, and a third hole.

[0005] Preferably, the second auxiliary arm has a first hole, a second hole, and a third hole inside.

[0006] Preferably, the upper ends of the first auxiliary arm and the second auxiliary arm are 8 cm away from the first rotating shaft, and the lower ends of the first auxiliary arm and the second auxiliary arm are 4 cm away from the first rotating shaft.

[0007] Preferably, the inner diameter of the first hole is 4 mm and the inner diameter of the second hole is 3 mm.

[0008] Preferably, the inner diameter of the third hole is the same as that of the first pivot in millimeters.

[0009] Preferably, the first auxiliary arm has a movable groove inside, the inner wall of the movable groove is movably connected to a second rotating shaft, the outer wall of the second rotating shaft is fixedly connected to a limit screw, the outer wall of the limit screw is movably connected to a limit nut, and the second auxiliary arm has an clearance groove inside.

[0010] Preferably, the first auxiliary arm forms a rotating structure with a second rotating shaft and a limiting screw, and the limiting screw is movably connected to the first auxiliary arm through a movable slot.

[0011] Preferably, the limiting screw is movably connected to the second auxiliary arm via a clearance groove.

[0012] Preferably, the first auxiliary arm is hinged to the second auxiliary arm via a first pivot, and the limiting screw is threadedly connected to the limiting nut.

[0013] Preferably, the limiting nut is movably installed on one side of the second auxiliary arm, and the limiting nut is compatible with the limiting screw.

[0014] The parallel planting aid provided by this invention has the following advantages: The device is equipped with a first auxiliary arm, a first rotating shaft, a second auxiliary arm, a first hole, a second hole, a third hole, a limiting screw, and a limiting nut. The upper ends of the first and second auxiliary arms are 8 cm away from the first rotating shaft, while the lower ends are 4 cm away from the first rotating shaft. The intersection point is longer at the top and shorter at the bottom, which can adapt to the mouth opening. The short lower branch can extend into the narrow operating space of the patient's mouth, adapting to the natural mouth opening range. It will not press against the upper and lower lips or cheek soft tissue due to excessive arm length. There is no need to repeatedly pull the corners of the mouth during the operation, which greatly improves the adaptability of the operating space inside the mouth, reduces the risk of instrument squeezing and scratching the oral mucosa, and improves the patient's comfort during the operation. Furthermore, since the first and second auxiliary arms are respectively provided with a first hole, a second hole and a third hole, and the diameters of the three sets of holes are different, they can be selected and matched according to the actual dental implant needs. For different surgical scenarios such as single implantation, continuous multi-tooth repair implantation, small diameter implantation in the anterior region, and large diameter loading implantation in the posterior region, the corresponding hole diameter can be flexibly selected to cooperate with the guide. Furthermore, the dual-hole co-clamping of the drill rod on the same side arm can limit the radial swing of the drill bit and prevent the drill tool from tilting and shaking during the drilling process. Combined with the scissor-type cross-hinged structure, it synchronously constrains the included angle of the drill rods on both sides. The double limit stabilizes and maintains the parallelism of multiple planting drill tool axes, effectively eliminating the angle deviation problem that is prone to occur in single-point guidance and improving the coaxiality accuracy of planting hole preparation. Furthermore, by pressing the first auxiliary arm and the second auxiliary arm, the first and second auxiliary arms can be rotated and adjusted under the action of the first rotating shaft. When the opening angle is appropriate, rotating the limiting nut can position the limiting screw, thereby driving the first and second auxiliary arms to be limited to the required opening angle. This facilitates the adjustment and limiting of the opening angle of the first and second auxiliary arms according to actual usage requirements. Attached Figure Description

[0019] Reference Figure 1 , Figure 2 and Figure 3As shown, a first auxiliary support arm 1 is movably connected to a first rotating shaft 2, and a second auxiliary support arm 3 is movably connected to the outer wall of the first rotating shaft 2. A first hole 4, a second hole 5, and a third hole 6 are opened inside the first auxiliary support arm 1. The second auxiliary support arm 3 also has a first hole 4, a second hole 5, and a third hole 6. The upper ends of the first and second auxiliary support arms 1 and 3 are 28 cm away from the first rotating shaft, and the lower ends are 24 cm away from the first rotating shaft. The inner diameter of the first hole 4 is 4 mm, the inner diameter of the second hole 5 is 3 mm, and the inner diameter of the third hole 6 is 2 mm.

[0020] The upper ends of the first auxiliary arm 1 and the second auxiliary arm 3 are 28 cm away from the first rotating shaft, while the lower ends of the first auxiliary arm 1 and the second auxiliary arm 3 are 24 cm away from the first rotating shaft. The intersection point is longer at the top and shorter at the bottom, which can adapt to the oral cavity opening. Since the first auxiliary arm 1 and the second auxiliary arm 3 have a first hole 4, a second hole 5 and a third hole 6 respectively, and the diameter of the three sets of holes is different, they can be adapted and matched according to the actual dental implant needs.

[0021] Reference Figure 1 , Figure 4 and Figure 5 As shown, the first auxiliary support arm 1 has a movable groove 7 inside, and a second rotating shaft 8 is movably connected to the inner wall of the movable groove 7. A limit screw 9 is fixedly connected to the outer wall of the second rotating shaft 8, and a limit nut 10 is movably connected to the outer wall of the limit screw 9. The second auxiliary support arm 3 has a clearance groove 11 inside. The first auxiliary support arm 1 forms a rotating structure with the limit screw 9 through the second rotating shaft 8. The limit screw 9 is movably connected to the first auxiliary support arm 1 through the movable groove 7, and the limit screw 9 is movably connected to the second auxiliary support arm 3 through the clearance groove 11. The first auxiliary support arm 1 is hinged to the second auxiliary support arm 3 through the first rotating shaft 2. The limit screw 9 and the limit nut 10 are threadedly connected. The limit nut 10 is movably installed on one side of the second auxiliary support arm 3, and the limit nut 10 is compatible with the limit screw 9.

[0022] By pressing the first auxiliary arm 1 and the second auxiliary arm 3, the first auxiliary arm 1 and the second auxiliary arm 3 can be rotated and adjusted under the action of the first rotating shaft 2. Under the action of the second rotating shaft 8, the limiting screw 9 rotates along the first auxiliary arm 1 and slides along the clearance groove 11 opened inside the second auxiliary arm 3. When the opening angle is appropriate, the limiting nut 10 is rotated. Since the limiting screw 9 and the limiting nut 10 are threadedly connected, the limiting screw 9 can be positioned, thereby driving the first auxiliary arm 1 and the second auxiliary arm 3 to be limited according to the required opening angle.
