[0016] The technical scheme in the embodiments of the utility model will be described clearly and completely below with reference to the drawings in the embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor fall within the scope of protection of the utility model.

[0017] Please refer to Figure 1The utility model provides a kind of dental implant guide plate, including guide plate body 1 and guide ring 2, the guide ring 2 is embedded in the guide plate body 1, the guide plate body 1 is used to be in contact with gum, the guide ring 2 is used to align implant area, the inner wall surface of the guide ring 2 is equipped with guide groove 11, the guide groove 11 is helical structure, the guide ring 2 is equipped with liquid inlet hole 12 and liquid outlet hole 13, the liquid inlet hole 12 and the liquid outlet hole 13 are respectively communicated with the both ends of the guide groove 11, the guide groove 11 is used to guide the cooling liquid in the liquid inlet hole 12 to the liquid outlet hole 13 and discharge.

[0018] Specifically, the guide plate body 1 of the present application can be directly attached to the gum. After the guide plate body 1 is fixed to the gum bed, the drill bit can be inserted into the guide ring 2 to drill holes in the gum bed. The cooling liquid (usually water) directly enters the guide groove 11 from the liquid inlet hole 12. The cooling liquid in the guide groove 11 can carry away the heat generated during drilling by the drill bit. Due to the special helical structure of the guide groove 11, the cooling liquid is continuously drawn and adjusted during flow, so that the flow direction and speed of the cooling liquid can be more accurately matched with the design target, improving the guide efficiency and heat dissipation efficiency. At the same time, during the drilling process, blood and bone fragments are discharged from the implant area. During the cooling process of the gum bed, the cooling liquid can carry the blood and bone fragments along the guide groove 11 and discharge them from the liquid outlet hole 13. During the drilling process, the operator connects the water pumping device to the liquid outlet hole 13. At this time, the liquid outlet hole 13 guides the cooling liquid, blood and bone fragments in the implant area to discharge, which is faster, and the residue of blood and bone fragments in the implant area is less. The drilling is faster, more stable and more accurate. Overall, the implant surgery time is saved from multiple aspects, and the efficiency of the operation is improved.

[0019] In a feasible embodiment, the central axis of the liquid inlet hole 12 forms an angle with the radial line of the guide ring 2. Since the guide groove 11 is arranged on the inner wall surface of the guide ring 2, in order to minimize the kinetic energy loss of the cooling liquid when it enters the guide groove 11 from the liquid inlet hole 12, the angle between the central axis of the liquid inlet hole 12 and the tangent direction of the guide groove 11 is as small as possible. In this embodiment, the central axis of the liquid inlet hole 12 forms an angle with the radial line of the guide ring 2, which can make the cooling liquid enter at a certain angle when it enters the guide ring 2, which helps to guide the cooling liquid to the guide groove 11, avoids unnecessary impact and turbulence when the cooling liquid enters the guide ring 2 vertically, and thus improves the flow stability of the fluid. At the same time, the water inlet hole makes the cooling liquid obtain a certain inclined motion when it enters the guide groove 11, thereby improving the flow path of the cooling liquid. In this embodiment, the design of the liquid inlet hole 12 helps to reduce the resistance of the cooling liquid when it enters and optimize the flow path.

[0020] Please refer to Figure 2In an embodiment, the flow guide groove 11 is provided with a plurality of flow guide protrusions 111, which are used to disturb the flow of the cooling liquid in the flow guide groove 11. In this embodiment, the flow guide protrusions 111 change the flow path of the fluid, causing a certain turbulence or disturbance to the fluid. In the process of cooling the drill bit, appropriate turbulence helps to improve the heat transfer efficiency of the cooling liquid and improve the cooling effect.

[0021] In an embodiment, the flow guide protrusions 111 are formed with flow guide slopes that are inclined from the liquid inlet hole 12 to the liquid outlet hole 13. In this embodiment, the inclination of the flow guide slopes from the liquid inlet hole 12 to the liquid outlet hole 13 helps to reduce the stagnation and dead zone of the cooling liquid in the groove. During the flow of the cooling liquid, some areas may be stagnant due to slow flow or reverse flow, which may increase energy loss or cause system instability. The slope can guide the fluid to flow along the slope direction, reducing the stagnation phenomenon and improving the flow efficiency.

[0022] In an embodiment, the diameter of the liquid outlet hole 13 is larger than that of the liquid inlet hole 12. Because blood and bone fragments may be generated during the drilling process, the flow rate of the liquid entering from the liquid inlet hole 12 is greater than that of the liquid flowing out from the liquid outlet hole 13. The diameter of the liquid outlet hole 13 is larger than that of the liquid inlet hole 12, so that the liquid in the flow guide groove 11 flows more smoothly, avoiding pressure accumulation or blockage due to liquid outflow obstruction.

[0023] In an embodiment, the liquid inlet hole 12 is located on the end of the guide ring 2 close to the gum, and the liquid outlet hole 13 is located on the end of the guide ring 2 away from the gum. Because the end of the guide ring 2 close to the gum is closest to the bone during the drilling process, it is closest to the source of heat generation. Therefore, the temperature of the cooling liquid entering the flow guide groove 11 from the liquid inlet hole 12 is the lowest, and the heat transfer efficiency is the highest. Therefore, this embodiment can greatly improve the heat transfer efficiency of the flow guide.

[0024] In an embodiment, the guide plate body 1 is provided with a plurality of viewing windows 3, which are used to view the fit between the guide plate body 1 and the gum. The viewing windows 3 in this embodiment provide real-time and direct visual feedback for the doctor, accurately grasp the fit between the guide plate body 1 and the gum, and make the entire surgical process more accurate.
