Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and to a device for calibrating implant handpieces or implant robotic arms before dental implantation. Background Technology

[0002] Dental implant surgery involves inserting an implant into the patient's alveolar bone and fixing an abutment and crown to the implant to form a dental implant. Dental implants replace natural teeth to solve the problem of tooth loss in oral patients, and can also improve facial appearance and chewing function.

[0003] The dental instruments in this technical solution specifically refer to implant handpieces and implant robotic arms. The implant surgery procedure includes the following steps: taking a CT scan of the patient's mouth, developing an implantation plan based on the CT results, drilling implant holes in the alveolar bone according to the plan, inserting the implant into the holes, and then fixing the abutment and crown onto the implant. During the drilling stage, drilling can generally be performed by an operator using a handpiece or automatically controlled by an implant robotic arm. Regardless of whether it's done with a handpiece or a robotic arm, the dental instruments need to be calibrated before the implantation procedure.

[0004] The calibration process involves installing a known calibration device onto the dental instrument, using a binocular navigation system to collect the real-time position and orientation of the calibration device, and then determining the accurate position and orientation of the dental instrument in the binocular navigation system's three-dimensional coordinate system based on the data collected. Existing calibration devices for dental instruments suffer from excessive mass. Utility Model Content

[0008] The calibration plane plate has a regular polygonal structure. The calibration plane plate is hollowed out to form a calibration support strip.

The side wall glue overflow grooves are located at the four corners of the ceramic piece fixing recess, and a ring of bottom wall glue overflow grooves is provided on the bottom wall of the ceramic piece fixing recess.

[0049] Dental implant surgery involves inserting an implant into the patient's alveolar bone and fixing an abutment and crown to the implant to form a dental implant. Dental implants replace natural teeth to solve the problem of tooth loss in oral patients, and can also improve facial appearance and chewing function.

[0050] The dental instruments in this technical solution specifically refer to implant handpieces and implant robotic arms. The implant surgery procedure includes the following steps: taking a CT scan of the patient's mouth, developing an implantation plan based on the CT results, drilling implant holes in the alveolar bone according to the plan, inserting the implant into the holes, and then fixing the abutment and crown onto the implant. During the drilling stage, drilling can generally be performed by an operator using a handpiece or automatically controlled by an implant robotic arm. Regardless of whether it's done with a handpiece or a robotic arm, the dental instruments need to be calibrated before the implantation procedure.

[0051] The calibration process involves installing a known calibration device onto the dental instrument, using a binocular navigation system to collect the real-time position and orientation of the calibration device, and then determining the accurate position and orientation of the dental instrument in the binocular navigation system's three-dimensional coordinate system based on the data collected. Existing calibration devices for dental instruments suffer from excessive mass.

[0052] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, to solve the above problems, this utility model provides a calibration device for oral treatment instruments, including a calibration plane plate, a connector 4, and mounting bolts 5. The calibration plane plate, with multiple optical markers 3 disposed thereon, provides real-time images for the binocular navigation device, thereby serving as a positioning marker. The connector 4 and the mounting bolts 5 cooperate to fix the calibration plane plate onto the implant handpiece and implant robotic arm, thereby facilitating calibration operations on the implant handpiece or implant robotic arm.

[0053] The calibration plane plate has a regular polygonal structure, and the calibration plane plate is hollowed out to form a calibration support strip 1. The calibration support strip 1 has a ring-shaped structure, and a support ring 2 is formed in the center of the calibration support strip 1. The function of the calibration support strip 1 is to fix the optical marker 3, while the function of the support ring 2 is to cooperate with the plug-in assembly 4 and the mounting bolt 5 to fix the device to dental treatment instruments such as implant handpieces and implant robotic arms.

[0054] The plug-in assembly 4 includes a fixed sleeve 401 and a plug-in rod 402. The fixed sleeve 401 and the plug-in rod 402 are fixedly connected through adjacent ends. The fixed sleeve 401 and the plug-in rod 402 are coaxially arranged. The fixed sleeve 401 has an internal threaded through hole 403 at the end away from the plug-in rod 402.

[0055] The mounting bolt 5 includes a drive nut 501 and a connecting threaded rod 502. The connecting threaded rod 502 is fixedly disposed on the bottom surface of the drive nut 501. A hexagonal recess 503 is formed in the center of the top surface of the drive nut 501. The connecting threaded rod 502 passes through the support ring 2 and is threadedly connected to the internal threaded through hole 403 on the fixing sleeve 401. The drive nut 501 is abutted and fixed on the support ring 2.

[0056] During installation, after passing the mounting bolt 5 through the support ring 2, the threaded rod 502 on the mounting bolt 5 is threaded into the internal threaded through hole 403 of the fixing sleeve 401 on the plug-in assembly 4, thus forming a complete structure with the calibration plane plate, the plug-in assembly 4, and the mounting bolt 5. Based on this, the device is then connected and fixed to the dental treatment instrument via the plug-in long rod 402 on the plug-in assembly 4. This allows for image acquisition of the optical marker 3 using a binocular navigation system, thereby completing the calibration operation. It should be noted that this technical solution only creatively improves the device structure; the principle and steps of the calibration operation are existing technology, and this technical solution does not modify them.

[0057] Based on the above structure, a calibration support belt 1 is formed by hollowing out the calibration plane plate. The ring-shaped calibration support belt 1 provides a sufficiently large image acquisition area to ensure that the binocular navigator can acquire images efficiently and stably. At the same time, the hollow structure can greatly reduce the weight and improve the ease of operation.

[0058] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a first support rod 101, a second support rod 102, a third support rod 103, and a fourth support rod 104 are formed by a hollowed-out section between the calibration support band 1 and the support ring 2. One end of each of the first support rod 101, the second support rod 102, the third support rod 103, and the fourth support rod 104 is fixedly disposed on the inner ring of the calibration support band 1, and the other end of each of the first support rod 101, the second support rod 102, the third support rod 103, and the fourth support rod 104 is fixedly disposed on the outer ring of the support ring 2.

[0059] In this technical solution, a calibration support strip 1 is formed by hollowing out the calibration plane plate, along with a support ring 2 and first support rods 101, second support rods 102, third support rods 103, and fourth support rods 104. Based on the above structure, the support ring 2 enables the installation function, and with the help of the plug-in assembly 4 and mounting bolts 5, the device can be installed on the planting mobile phone and planting robotic arm to be calibrated. The support ring 2 and the calibration support strip 1 are connected and fixed by the first support rods 101, second support rods 102, third support rods 103, and fourth support rods 104, which can improve the stability of the device structure.

[0060] like Figure 3 and Figure 4 As shown, the support ring 2 is provided with a top countersunk hole 201 and a bottom countersunk hole 202. The top countersunk hole 201 is located at the center of the top surface of the support ring 2, and the bottom countersunk hole 202 is located at the center of the bottom surface of the support ring 2.

[0061] During installation, when the mounting bolt 5 passes through the support ring 2 and is fixedly connected to the plug-in assembly 4, the drive nut 501 is located in the countersunk hole 201 on the top surface, and the end of the fixing sleeve 401 is located in the countersunk hole 202 on the bottom surface.

[0062] Based on the above structure, by providing a countersunk hole 201 on the top surface, the drive nut 501 of the mounting bolt 5 can be prevented from protruding from the calibration plane plate, thus preventing it from affecting external objects; by providing a countersunk hole 202 on the bottom surface and fitting the end of the fixing sleeve 401 into the countersunk hole 202 on the bottom surface, the connection and fixing effect of the fixing sleeve 401 is better.

[0063] Preferably, the top surface of the calibration plane plate is provided with 5 optical markers 3, and the bottom surface of the calibration plane plate is provided with 5 optical markers 3. Providing 5 optical markers 3 on both the top and bottom surfaces of the calibration plane plate expands the applicable angle of the device, ensuring that one side of the device always faces the binocular navigator, thus guaranteeing that the binocular navigator can effectively acquire image data from the optical markers 3.

[0064] Preferably, the optical marker 3 includes a ceramic sheet, on which a first white triangular block 301, a second white triangular block 302, a first black sector block 303, and a second black sector block 304 are disposed; the vertices of the first white triangular block 301, the second white triangular block 302, the first black sector block 303, and the second black sector block 304 coincide, the first white triangular block 301 and the second white triangular block 302 are disposed opposite each other, and the first black sector block 303 and the second black sector block 304 are disposed opposite each other.

[0065] Based on the above structure, the first white triangular block 301, the first black fan-shaped block 303, the second white triangular block 302, and the second black fan-shaped block 304 are sequentially adjacent to each other to form an optical marker 3 on the ceramic sheet. The recognition of the optical marker 3 is improved by using the color contrast of black and white intervals.

[0066] like Figure 2 and Figure 5 As shown, the calibration support belt 1 has a ceramic piece fixing recess 105, and the ceramic piece fixing recess 105 is provided with four side wall glue overflow grooves 106. The side wall glue overflow grooves 106 are located at the four corners of the ceramic piece fixing recess 105. A bottom wall glue overflow groove 107 is provided on the bottom wall of the ceramic piece fixing recess 105. The optical marker 3 is bonded and fixed in the ceramic piece fixing recess 105.

[0067] The optical marker 3 is fixed to the ceramic plate fixing recess 105 by adhesive bonding. The bonding process is as follows: after applying adhesive to the bottom surface of the optical marker 3, the optical marker 3 is embedded into the ceramic plate fixing recess 105, and the bonding is completed after the adhesive has cured. In order to ensure the bonding effect, it is necessary to ensure that the amount of adhesive is slightly more. However, since the space between the ceramic plate fixing recess 105 and the optical marker 3 is very limited, the excess adhesive will inevitably overflow. If the overflow covers the area of ​​the first white triangular block 301, the first black fan-shaped block 303, the second white triangular block 302, and the second black fan-shaped block 304, it will affect the positioning and marking function of the optical marker 3.

[0068] Based on the above structure, the optical marker 3 is bonded and fixed in the ceramic plate fixing recess 105, which can prevent the optical marker 3 from protruding from the calibration plane plate and prevent it from affecting external objects. At the four corners of the ceramic plate fixing recess 105, a side wall overflow groove 106 is provided, and a bottom wall overflow groove 107 is provided on the bottom wall of the ceramic plate fixing recess 105. The extra space of the side wall overflow groove 106 and the bottom wall overflow groove 107 can prevent excess adhesive from overflowing.

[0069] like Figure 1 , Figure 2 and Figure 3 As shown, preferably, the top surface of the calibration plane plate is provided with a raised edge 108. The raised edge 108 on the top surface of the calibration plane plate protects the optical marker 3, preventing it from being scratched and losing its image marking function when the device is accidentally inverted.

[0070] Specifically, the calibration support band 1 and the support ring 2 are integrally formed aluminum alloy structures. Aluminum alloy has the characteristics of being lightweight and high-strength. Using an integrally formed aluminum alloy structure as the calibration support band 1 and the support ring 2 helps to improve the strength of the device while reducing its weight, making calibration operations easier.

[0071] like Figure 1 , Figure 2 and Figure 3 As shown, preferably, the calibration plane plate is provided with a plurality of spherical calibration grooves 6 and a plurality of conical calibration grooves 7.

[0072] During ball head calibration, the ball head is mounted and fixed on the implantation handpiece, and then the implantation handpiece abuts the ball head against the spherical calibration groove 6. Since the positional relationship between the hemispherical recess and the calibration plane plate is known, the ball head calibration operation of the implantation handpiece can be completed based on the data collected by the binocular navigation system. Similarly, the conical calibration groove 7 is used to calibrate the pointed drill bit of the implantation handpiece, and the spherical calibration groove 6 is used to calibrate the ball head drill bit of the implantation handpiece. In use, during tip calibration, the drill bit is mounted and fixed on the implantation handpiece, and the implantation handpiece controls the drill bit to abut against the conical calibration groove 7. Since the positional relationship between the conical recess and the calibration plane plate is known, the tip calibration operation of the implantation handpiece can be completed based on the data collected by the binocular navigation system. Based on the above structure, the spherical calibration groove 6 and the conical calibration groove 7 are provided on the calibration plane plate, which can perform comprehensive calibration of the implantation handpiece. The simple structure meets multiple calibration needs and has the advantages of scientific structure and complete functions. It should be noted that the principles and steps of the ball head calibration operation and the tip calibration operation are existing technologies, and the innovation of this technical solution does not lie in these.

[0073] It should be understood that the application of this utility model is not limited to the examples above. Those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
