[0051] Optical locators and implant handpieces are essential equipment for implant surgery navigation. The infrared light emitted by the optical locator is reflected after hitting the marking point on the implant handpiece. After the optical locator captures the reflected infrared light, it can obtain the real-time position and real-time posture of the implant handpiece. By dynamically comparing the real-time position, ideal position, real-time posture, and ideal posture, the implant handpiece can be navigated step by step in real time, guiding the implant handpiece to run along the most ideal trajectory.

[0052] The prerequisite for completing the above operations is that the implant mobile phone has been calibrated. The so-called calibration refers to the process of unifying the three-dimensional coordinate system of the implant mobile phone and the three-dimensional coordinate system of the optical locator. After the calibration operation, the optical locator can locate the implant mobile phone in real time during the operation through the reflected infrared light.

[0053] According to the different oral environments of patients, the implant mobile phone needs to be adaptively configured. For example, when equipped with a drill bit or a ball head, in addition to operating the coordinate system, it is also necessary to calibrate the drill position, drill position and outer diameter. The calibration plate used for calibration operations in the prior art has a single function problem. It can only perform three-dimensional coordinate system one. If drill bit calibration or ball head calibration is required, additional calibration tools are required, which brings great inconvenience to the operation.

[0054] like Figure 1 As shown, in order to solve the above problems, the utility model provides a multifunctional three-dimensional calibration plate, including a calibration body 1, a marking point 2, a direction calibration column 3, a conical calibration pit 4, an outer diameter calibration groove 5 and a ball head calibration pit 6. The calibration body 1 is the main structure of the device, which plays a structural support role. The marking point 2, the direction calibration column 3, the conical calibration pit 4, the outer diameter calibration groove 5 and the ball head calibration pit 6 are arranged on the calibration body 1; the function of the marking point 2 is to exchange information with the optical positioning system, and the device is positioned in real time through the marking point 2; the function of the direction calibration column 3 is to axially position the implant mobile phone 8, and the axial direction of the implant mobile phone 8 is determined by plugging the implant mobile phone 8 into the direction calibration column 3; the function of the conical calibration pit 4 is to accurately determine the tip position of the implant mobile phone 8 drill bit; the function of the outer diameter calibration groove 5 is to measure the outer diameter of the implant mobile phone 8 drill bit; the function of the ball head calibration pit 6 is to determine the ball center and position of the ball head of the implant mobile phone 8.

[0055] Among them, the calibration body 1 is a three-dimensional multi-faceted structure, and a plurality of side surfaces are arranged on the calibration body 1; at least four identification points 2 are arranged, and a plurality of identification points 2 are arranged on the same side surface of the calibration body 1; at least one direction calibration column 3 is arranged, and the direction calibration column 3 is a cylindrical structure, and the direction calibration column 3 is fixedly arranged on one or more side surfaces of the calibration body 1, and the planting mobile phone 8 is movably mounted on the direction calibration column 3; one of the side surfaces of the calibration body 1 is formed into a conical side wall by inward depression, and the calibration body 1 forms the conical calibration pit 4 through the conical side wall, and the conical calibration pit 4 forms a circular opening at the top and a pointed cone bottom at the bottom. The cross-sectional area of ​​the conical calibration pit 4 gradually increases from the pointed cone bottom to the circular opening; one of the side surfaces of the calibration body 1 is recessed inward to form a vertical side wall, and the calibration body 1 forms the outer diameter calibration groove 5 through the vertical side wall, and the outer diameter of the outer diameter calibration groove 5 gradually increases from one end to the other end; simply put, the outer diameter calibration groove 5 is a structure with one end wide and one end narrow on one of the side surfaces of the calibration body 1, and when the drill bit is just clamped and fixed on the outer diameter calibration groove 5, its outer diameter can be directly obtained; one of the side surfaces of the calibration body 1 is recessed inward to form a hemispherical side wall, and the calibration body 1 forms the ball head calibration pit 6 through the hemispherical side wall.

[0056] During the calibration process of the planting mobile phone 8, the optical locator collects real-time positioning information on the planting mobile phone 8, and at the same time collects real-time positioning information of this device through the identification point 2. Through the above two real-time positioning information, a coordinate conversion relationship is established between any two of the three-dimensional coordinate system of the optical locator, the three-dimensional coordinate system of the planting mobile phone 8 and the three-dimensional coordinate system of the calibration plate.

[0057] When performing axial calibration, the implant mobile phone 8 is plugged into the direction calibration column 3 and the implant mobile phone 8 is abutted against the side of the calibration body 1, so that the mobile phone connection sleeve and the direction calibration column 3 form a coaxial relationship. Since the positional relationship between the direction calibration column 3 and the calibration body 1 is known, the axial calibration operation of the implant mobile phone 8 can be completed based on the coordinate conversion relationship between the three-dimensional coordinate system of the implant mobile phone 8 and the three-dimensional coordinate system of the calibration plate. When performing tip calibration, the drill bit is fixed on the implant mobile phone 8, and the drill bit is controlled by the implant mobile phone 8 to abut against the conical calibration pit 4. Since the positional relationship between the conical calibration pit 4 and the calibration body 1 is known, the tip calibration operation of the implant mobile phone 8 can be completed based on the coordinate conversion relationship between the three-dimensional coordinate system of the implant mobile phone 8 and the three-dimensional coordinate system of the calibration plate. When measuring the outer diameter, the drill bit is mounted and fixed on the implant mobile phone 8, and then the drill bit is sleeved on the thicker end of the outer diameter calibration groove 5, and the drill bit is gradually moved toward the thinner end by operating the implant mobile phone 8 until the drill bit is clamped and fixed. Since the positional relationship between the outer diameter calibration groove 5 and the calibration body 1 is known, the outer diameter of the drill bit can be known by the position of the drill bit in the outer diameter calibration groove 5 at this time. When calibrating the ball head, the ball head is mounted and fixed on the implant mobile phone 8, and then the ball head is abutted against the ball head calibration pit 6 by the implant mobile phone 8. Since the positional relationship between the ball head calibration pit 6 and the calibration body 1 is known, the ball head calibration operation of the implant mobile phone 8 can be completed based on the coordinate conversion relationship between the three-dimensional coordinate system of the implant mobile phone 8 and the three-dimensional coordinate system of the calibration plate. The above calibration process is a technical solution in the prior art. The present application does not make creative improvements to the calibration process, and only achieves the expected technical effect through structural optimization.

[0058] In a specific embodiment, the identification points 2 can be set to four, five or six. According to the triangulation positioning principle, the optical locator only needs to collect information of three identification points at the same time to perform real-time positioning. Therefore, multiple identification points 2 are set on the same side of the calibration body 1 to facilitate simultaneous collection by the optical locator. At least one direction calibration column 3 is set, and multiple direction calibration columns 3 can also be set; for example, three direction calibration columns 3 are set, respectively set on three sides of the calibration body 1, so that the planting mobile phone can be calibrated in multiple directions.

[0059] Based on the above structure, multiple side surfaces are formed on the three-dimensional multi-faceted calibration body 1, and various functional units such as identification points 2, direction calibration columns 3, conical calibration pits 4, outer diameter calibration grooves 5 and ball head calibration pits 6 are integrated. The above functional units can be set on one or more side surfaces of the calibration body 1 according to application needs, which is convenient for comprehensive calibration of the implant mobile phone 8 before the implementation of the dental implant surgery. It has the advantages of scientific structure and complete functions.

[0060] like Figure 1As shown, a drill length calibration portion 7 is provided on one side surface of the calibration body 1, and the drill length calibration portion 7 includes a circular positioning groove, and a circular calibration disk 701 is attached and fixed in the circular positioning groove.

[0061] When performing length calibration, the drill bit is installed and fixed on the planting mobile phone 8, and the drill bit is controlled by the planting mobile phone 8 to abut against the circular calibration disk 701. Since the positional relationship between the circular calibration disk 701 and the calibration body 1 is known, the length calibration operation of the planting mobile phone 8 can be completed based on the coordinate conversion relationship between the three-dimensional coordinate system of the planting mobile phone 8 and the three-dimensional coordinate system of the calibration plate.

[0062] Based on the above structure, in addition to functional units such as the marking point 2, the direction calibration column 3, the conical calibration pit 4, the outer diameter calibration groove 5 and the ball head calibration pit 6, a drill bit length calibration part 7 is also provided to facilitate the length calibration of the drill bit, thereby further improving the function of the device.

The purpose of providing the circular protrusion 702 at the bottom of the circular positioning groove is to form the annular groove 703. If the circular calibration disk 701 is only glued and fixed to the flat bottom of the circular positioning groove, the problem of insufficient gluing will occur. In this embodiment, the annular groove 703 is formed by a special structural design, and the space of the annular groove 703 can be fully filled with glue, which can improve the bonding and fixing effect.

[0067] When performing axial calibration, the implant mobile phone 8 should abut against the side of the calibration body 1 so that the mobile phone connection sleeve and the direction calibration column 3 are coaxial and fixed to each other. If the implant mobile phone 8 and the calibration body 1 are abutted through two planes, the two planes may not be able to fit together due to operational errors. To solve this problem, the technical solution is provided with an annular raised ring 801.
