Description

Technical Field

[0001] This utility model relates to the field of medical equipment technology, and to a device for calibrating surgical equipment such as reference plates and registration devices before performing dental implant surgery. Background Technology

[0002] Dental implant surgery demands extremely high precision and timeliness. The surgeon must precisely control the implant handpiece and strictly adhere to the implantation plan best suited to the patient's oral condition to ensure the desired outcome. The procedure utilizes equipment including, but not limited to, CT scanners, binocular cameras, reference plates, and registration devices. To achieve the aforementioned high precision and timeliness requirements, the surgeon must calibrate the reference plate and registration device before the surgery to ensure consistency in three-dimensional coordinates across different instruments such as the CT scanner and binocular camera.

[0003] The principle and process of calibrating dental implant surgery equipment before surgery is as follows: the structural parameters of the calibration device itself are known; a binocular camera collects real-time data from the calibration device; a CT scanner collects real-time data from the registration device; and using the known parameters of the calibration device itself, the calibration of surgical equipment such as the reference plate and registration device can be completed. It should be noted that the above principle and process represent existing technology in the field of dental implant surgery.

[0004] For the purpose of reducing overall weight, the calibration devices in the existing technology are limited by their small size. This results in the relative distance between the multiple reflective marking components used for positioning being too small, which is not conducive to reducing image recognition errors and has a negative impact on the navigation accuracy of subsequent dental implant surgery. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a dental implant surgery equipment calibration device that reduces image recognition error and ensures the navigation accuracy of dental implant surgery by increasing the relative distance between multiple reflective marking components, in order to address the above-mentioned deficiencies of the prior art.

[0006] The technical solution adopted by this utility model to solve the technical problem is as follows:

[0007] A dental implant surgery equipment calibration device, comprising:

[0008] A grip rod, wherein the grip rod is a long rod-shaped structure;

[0009] The mounting rod is fixedly disposed at the front end of the gripping rod. The mounting rod and the gripping rod are perpendicular to each other. The mounting rod and the gripping rod form an L-shaped structure. A calibration drill bit assembly is detachably disposed at the end of the mounting rod away from the gripping rod.

[0010] The first three-dimensional support, the extension connector, and the second three-dimensional support are provided. The rear end of the grip rod is fixedly disposed on the first three-dimensional support. The first three-dimensional support is connected to the second three-dimensional support as a whole through the extension connector. The first three-dimensional support and the second three-dimensional support are respectively provided with multiple recognition planes, and at least one reflective marking component is provided on the recognition plane.

[0011] Compared with the prior art, the beneficial effects of this technical solution are: multiple recognition planes are respectively set on the first three-dimensional support and the second three-dimensional support to fix the reflective marking components, and the two are connected and fixed by an extension connector, so that the interval between different reflective marking components is larger, which helps to reduce the image acquisition, recognition and processing error of the binocular navigator and makes the navigation process more accurate.

[0012] Furthermore, the first three-dimensional support member and the second three-dimensional support member are cuboid structures;

[0013] The outer surface of the first three-dimensional support member includes a first front end face, a first rear end face, and four first side faces; the first three-dimensional support member is connected to the rear end of the grip rod through the first front end face, the first three-dimensional support member is connected to the extension connector through the first rear end face, and the four first side faces form the identification plane;

[0014] The outer surface of the second three-dimensional support includes a second front end face, a second rear end face, and four second side faces; the second three-dimensional support is connected to the extension connector through the second front end face, and the four second side faces and the second rear end face form the identification plane.

[0015] The beneficial effects of adopting the above scheme are: both the first and second three-dimensional support components are set as cuboid structures. The cuboid structure is used to form a first front face, a first rear face, and four first side faces on the first three-dimensional support component, and a second front face, a second rear face, and four second side faces on the second three-dimensional support component. By using multiple side faces as recognition planes, the applicable angle of this device under the binocular camera view is improved.

[0016] Furthermore, the extension connector includes a first transverse connecting rod, a second transverse connecting rod, and three longitudinal extension rods;

[0017] The extension connector is fixedly connected to the first rear end face of the first three-dimensional support through the first transverse connecting rod, and the extension connector is fixedly connected to the second front end face of the second three-dimensional support through the second transverse connecting rod. The three longitudinal extension rods are equidistantly spaced, and the two ends of the three longitudinal extension rods are respectively fixedly mounted on the first transverse connecting rod and the second transverse connecting rod. The direction of the three longitudinal extension rods is consistent with the direction of the gripping rod.

[0018] The beneficial effects of adopting the above scheme are: the extension connector is formed by the first transverse connecting rod, the second transverse connecting rod and the three longitudinal extension rods, so that the extension connector forms a hollow structure to reduce the overall weight of the device; at the same time, the extension connector can also increase the distance between the first three-dimensional support and the second three-dimensional support, thereby making the spacing between the different reflective marking components set on the first three-dimensional support and the second three-dimensional support larger.

[0019] Furthermore, the gripping rod, the mounting rod, the first three-dimensional support member, the extension connector, and the second three-dimensional support member are integrally formed aluminum alloy structures.

[0020] The beneficial effects of adopting the above scheme are: the gripping rod, the mounting rod, the first three-dimensional support, the extension connector and the second three-dimensional support are connected to form the structural body of the device. The use of an integrally formed aluminum alloy structure as the structural body can improve the strength of the device while reducing its weight.

[0021] Furthermore, four reflective marking components are provided on the first rear end face, and two reflective marking components are distributed on each side of the extension connector on the first rear end face; two reflective marking components are provided on each of the first side faces; and one reflective marking component is provided on the second rear end face and each of the second side faces.

[0022] The beneficial effects of adopting the above scheme are: by utilizing the volume difference between the first three-dimensional support and the second three-dimensional support, two reflective marking components are set on the recognition plane of the first three-dimensional support and one reflective marking component is set on the recognition plane of the second three-dimensional support, so as to maximize the utilization of the plane; and the different arrangement directions of the reflective marking components on the first three-dimensional support and the second three-dimensional support are beneficial to the binocular camera for recognition and differentiation.

[0023] Furthermore, the reflective marking component includes a ceramic substrate and a first triangular region, a second triangular region, a first sector region, and a second sector region formed on the ceramic substrate. The first triangular region, the second triangular region, the first sector region, and the second sector region share a common vertex. The first triangular region and the second triangular region are spaced apart, and the first sector region and the second sector region are spaced apart. The first triangular region and the second triangular region are white regions, and the first sector region and the second sector region are black regions.

[0024] The beneficial effects of adopting the above scheme are: to form a distinct difference in shape and color on the reflective marking components, improve the recognizability of the reflective marking components from the perspective of the binocular camera, and facilitate binocular camera recognition.

[0025] Furthermore, adhesive recesses are formed on the identification planes of the first and second three-dimensional support members, and the reflective marking component is fixedly disposed in the adhesive recesses by adhesive glue.

[0026] The bottom of the adhesive recess is provided with a bottom surface glue overflow groove, which is arranged circumferentially along the bottom of the adhesive recess. The sides of the adhesive recess are provided with multiple side glue overflow grooves.

[0027] The beneficial effect of adopting the above solution is that it can effectively prevent adhesive overflow while ensuring the bonding and fixing effect of the reflective marking components.

[0028] Furthermore, the grip bar is provided with an anti-slip part.

[0029] The beneficial effect of adopting the above solution is that the anti-slip part on the grip increases the friction between the grip and the operator's hand, making it easier for the operator to grip and operate.

[0030] Furthermore, the drill bit assembly includes a mounting column and a cutting component. The mounting column is provided with an external threaded connection portion, and the mounting rod is provided with an internal threaded connection portion. The drill bit assembly is fixedly mounted on the mounting rod by the external threaded connection portion of the mounting column engaging with the internal threaded connection portion of the mounting rod. The cutting component is a tapered drill bit or a spherical drill bit.

[0031] The advantages of adopting the above scheme are: the cutting component can be detachably fixed to the mounting column to form a drill bit assembly, which makes it easy to switch between a tapered drill bit or a ball drill bit according to actual needs during calibration: switch to a tapered drill bit when it needs to abut against the patient's teeth, and switch to a ball drill bit when it needs to abut against the registration device.

[0032] Furthermore, the gripping rod gradually decreases in size from the end closest to the first three-dimensional support member to the end closest to the mounting rod.

[0033] The advantages of adopting the above scheme are: the structure of the grip rod gradually decreasing in size forward can adapt to the situation where the size of the mounting rod and the calibration drill bit assembly is small, while also improving the comfort of operation.

[0050] Dental implant surgery demands extremely high precision and timeliness. The surgeon must precisely control the implant handpiece and strictly adhere to the implantation plan best suited to the patient's oral condition to ensure the desired outcome. The procedure utilizes equipment including, but not limited to, CT scanners, binocular cameras, reference plates, and registration devices. To achieve the aforementioned high precision and timeliness requirements, the surgeon must calibrate the reference plate and registration device before the surgery to ensure consistency in three-dimensional coordinates across different instruments such as the CT scanner and binocular camera.

[0051] The principle and process of calibrating dental implant surgery equipment before surgery is as follows: the structural parameters of the calibration device itself are known; a binocular camera collects real-time data from the calibration device; a CT scanner collects real-time data from the registration device; and using the known parameters of the calibration device itself, the calibration of surgical equipment such as the reference plate and registration device can be completed. It should be noted that the above principle and process represent existing technology in the field of dental implant surgery.

[0052] For the purpose of reducing overall weight, the calibration device in the prior art is limited by its small size. This makes the relative distance between the multiple reflective marker components used for positioning too small. Considering that the binocular camera performs real-time positioning by combining images from multiple reflective marker components, the small relative distance between the reflective marker components is not conducive to reducing image recognition errors and has a negative impact on the navigation accuracy of subsequent dental implant surgery.

[0053] like Figure 1 and Figure 2 As shown, in order to solve the above problems, this utility model provides a dental implant surgery equipment calibration device, including a gripping rod 1, an installation rod 2, a first three-dimensional support 3, an extension connector 4, and a second three-dimensional support 5.

[0054] The gripping rod 1 is an elongated rod-shaped structure; the mounting rod 2 is fixedly disposed at the front end of the gripping rod 1, and the mounting rod 2 is perpendicular to the gripping rod 1. The mounting rod 2 and the gripping rod 1 form an L-shaped structure. A calibration drill bit assembly 201 is detachably disposed at the end of the mounting rod 2 away from the gripping rod 1. The calibration drill bit assembly 201 is used for cutting or other operations during dental implant surgery. In this technical solution, the direction towards the calibration drill bit assembly 201 is defined as "front," and the direction towards the second three-dimensional support member 5 is defined as "rear."

[0055] The rear end of the gripping rod 1 is fixedly mounted on the first three-dimensional support member 3. The first three-dimensional support member 3 is connected to the second three-dimensional support member 5 as a whole through the extension connector 4. Multiple recognition planes are respectively provided on the first three-dimensional support member 3 and the second three-dimensional support member 5, and at least one reflective marking component 6 is provided on each recognition plane. The innovation of this technical solution lies in the fact that the first three-dimensional support member 3 is connected to the second three-dimensional support member 5 as a whole through the extension connector 4, thereby increasing the relative distance between the first three-dimensional support member 3 and the second three-dimensional support member 5.

[0056] The binocular navigation system acquires image data from the calibration device and uses the pattern formed by multiple reflective marker components 6 on the calibration device to perform real-time positioning. In existing technologies, the pursuit of size reduction often results in excessively small relative distances between different reflective marker components 6. To address this issue, this technical solution sets both the first three-dimensional support 3 and the second three-dimensional support 5 as cuboid structures. The cuboid structure forms a first front face 301, a first rear face 302, and four first side faces 303 on the first three-dimensional support 3, and a second front face 501, a second rear face 502, and four second side faces 503 on the second three-dimensional support 5. Utilizing multiple side faces as recognition planes improves the applicable angle of this device under the binocular camera's viewpoint.

[0057] like Figure 1 and Figure 2 As shown, the first three-dimensional support 3 and the second three-dimensional support 5 are cuboid structures, that is, both the first three-dimensional support 3 and the second three-dimensional support 5 are hexahedral structures. More specifically, the cross-section of the first three-dimensional support 3 is larger than the cross-section of the second three-dimensional support 5. Since this device needs to be placed in front of the binocular camera during use, the above structural design improves the image acquisition success rate by preventing the second three-dimensional support 5, which is located on the outside, from obstructing the first three-dimensional support 3, while also balancing the overall weight of the device.

[0058] The outer surface of the first three-dimensional support member 3 includes a first front end face 301, a first rear end face 302, and four first side faces 303. The first three-dimensional support member 3 is connected to the rear end of the gripping rod 1 through the first front end face 301, and is connected to the extension connector 4 through the first rear end face 302. The four first side faces 303 form the recognition plane. Correspondingly, the outer surface of the second three-dimensional support member 5 includes a second front end face 501, a second rear end face 502, and four second side faces 503. The second three-dimensional support member 5 is connected to the extension connector 4 through the second front end face 501, and the four second side faces 503 and the second rear end face 502 form the recognition plane.

[0059] Based on the above structure, both the first three-dimensional support member 3 and the second three-dimensional support member 5 are set as cuboid structures. The first front end face 301, the first rear end face 302 and four first side faces 303 are formed on the first three-dimensional support member 3 using the cuboid structure, and the second front end face 501, the second rear end face 502 and four second side faces 503 are formed on the second three-dimensional support member 5. By using multiple side faces as recognition planes, the applicable angle of this device under the binocular camera view is improved.

[0060] like Figure 1 and Figure 2 As shown, preferably, the extension connector 4 includes a first transverse connecting rod 401, a second transverse connecting rod 402, and three longitudinal extension rods 403; the extension connector 4 is fixedly connected to the first rear end face 302 of the first three-dimensional support 3 through the first transverse connecting rod 401, and the extension connector 4 is fixedly connected to the second front end face 501 of the second three-dimensional support 5 through the second transverse connecting rod 402; the three longitudinal extension rods 403 are equidistantly spaced, and the two ends of the three longitudinal extension rods 403 are respectively fixedly disposed on the first transverse connecting rod 401 and the second transverse connecting rod 402; the direction of the three longitudinal extension rods 403 is consistent with the direction of the gripping rod 1.

[0061] Based on the above structure, an extension connector 4 is formed by the first transverse connecting rod 401, the second transverse connecting rod 402, and three longitudinal extension rods 403, creating a hollow structure in the extension connector 4 to reduce the overall weight of the device. The extension connector 4 can also increase the distance between the first three-dimensional support 3 and the second three-dimensional support 5, thereby increasing the spacing between the different reflective marking components 6 set on the first three-dimensional support 3 and the second three-dimensional support 5.

[0062] Specifically, the gripping rod 1, the mounting rod 2, the first three-dimensional support 3, the extension connector 4, and the second three-dimensional support 5 are integrally formed aluminum alloy structures. Based on the above structure, the gripping rod 1, the mounting rod 2, the first three-dimensional support 3, the extension connector 4, and the second three-dimensional support 5 are interconnected to form the structural body of this device. Using an integrally formed aluminum alloy structure as the structural body can improve the strength of this device while reducing its weight.

[0063] like Figure 1 and Figure 2 As shown, preferably, four reflective marking components 6 are provided on the first rear end face 302, and two reflective marking components 6 are distributed on each side of the extension connector 4 on the first rear end face 302; two reflective marking components 6 are provided on each of the first side faces 303; and one reflective marking component 6 is provided on the second rear end face 502 and each of the second side faces 503.

[0064] Specifically, the long axis of the reflective marking component 6 on the first three-dimensional support 3 extends in a direction perpendicular to the front-back direction, and the long axis of the reflective marking component 6 on the second three-dimensional support 5 extends in the front-back direction.

[0065] Based on the above structure, by utilizing the volume difference between the first three-dimensional support 3 and the second three-dimensional support 5, two reflective marking components 6 are set on the recognition plane of the first three-dimensional support 3, and one reflective marking component 6 is set on the recognition plane of the second three-dimensional support 5, so as to maximize the utilization of the plane. The reflective marking components 6 on the first three-dimensional support 3 and the second three-dimensional support 5 are arranged in different directions, which is beneficial for the binocular camera to identify and distinguish them.

[0066] like Figure 3As shown, preferably, the reflective marking component 6 includes a ceramic substrate 601 and a first triangular region 602, a second triangular region 603, a first sector region 604, and a second sector region 605 formed on the ceramic substrate 601. The first triangular region 602, the second triangular region 603, the first sector region 604, and the second sector region 605 have a common vertex. The first triangular region 602 and the second triangular region 603 are spaced apart, and the first sector region 604 and the second sector region 605 are spaced apart. The first triangular region 602 and the second triangular region 603 are white areas, and the first sector region 604 and the second sector region 605 are black areas.

[0067] The first triangular region 602, the second triangular region 603, the first sector region 604, and the second sector region 605 form an elliptical pattern. The base of the first triangular region 602 and the second triangular region 603 is the long side of the pattern of the reflective sign component 6, and the short side is the first sector region 604 and the second sector region 605. Therefore, the major axis of the reflective sign component 6 is an axis parallel to the base of the first triangular region 602 and the second triangular region 603 and passing through the geometric center of the reflective sign component 6; the minor axis of the reflective sign component 6 is an axis perpendicular to the base of the first triangular region 602 and the second triangular region 603 and passing through the geometric center of the reflective sign component 6.

[0068] Based on the above structure, a distinct shape and color difference is formed on the reflective marking component 6, which improves the recognizability of the reflective marking component 6 from the perspective of the binocular camera and facilitates binocular camera recognition.

[0069] like Figure 4 As shown, preferably, an adhesive recess 7 is formed on the identification plane of the first three-dimensional support 3 and the second three-dimensional support 5, and the reflective marking component 6 is fixedly disposed in the adhesive recess 7 by adhesive glue; a bottom overflow groove 701 is provided at the bottom of the adhesive recess 7, the bottom overflow groove 701 is arranged circumferentially along the bottom of the adhesive recess 7, and a plurality of side overflow grooves 702 are provided on the side of the adhesive recess 7.

[0070] Based on the above structure, while ensuring the bonding and fixing effect of the reflective marking component 6, it can effectively prevent the adhesive from overflowing.

[0071] like Figure 1 and Figure 2 As shown, preferably, the grip rod 1 is provided with an anti-slip part 101. The anti-slip part 101 on the grip rod 1 increases the friction between the grip rod 1 and the operator's hand, making it easier for the operator to grip and operate.

[0072] Preferably, the drill assembly includes a mounting post 202 and a cutting component 203. The mounting post 202 has an external threaded connection portion, and the mounting rod 2 has an internal threaded connection portion. The drill assembly is fixedly mounted on the mounting rod 2 by the threaded engagement between the external threaded connection portion of the mounting post 202 and the internal threaded connection portion of the mounting rod 2. The cutting component 203 is a tapered drill bit or a ball drill bit. The cutting component 203 is detachably fixed to the mounting post 202 to form the drill assembly, facilitating the switching between a tapered drill bit and a ball drill bit during calibration as needed: switching to a tapered drill bit when it needs to abut against the patient's teeth, and switching to a ball drill bit when it needs to abut against the registration device.

[0073] Preferably, the gripping rod 1 gradually decreases in size from the end closest to the first three-dimensional support member 3 towards the end closest to the mounting rod 2. This gradually decreasing size of the gripping rod 1 accommodates situations where the mounting rod 2 and the calibration drill bit assembly 201 are relatively small, while also ensuring comfortable handling.

[0074] 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.
