Description

Technical Field

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

[0002] When patients experience tooth loss, it can affect their eating and daily social interactions. The most direct and effective treatment is dental implants. Replacing missing teeth with implants has an immediate and significant effect on improving the oral and digestive health of patients with missing teeth, as well as enhancing their quality of life.

[0003] Dental implant surgery demands extremely high precision. A binocular navigation system can be used for real-time intraoperative navigation to ensure the most suitable implantation plan is implemented based on the patient's oral condition. The process roughly involves the binocular navigation system acquiring positioning markers on the implant handpiece to determine its real-time position, which is then compared with the predetermined implantation plan to provide real-time navigation for the handpiece.

[0004] An implant handpiece comprises a grip handle, a connector, and a working head. The grip handle is used to hold and hold the implant body, allowing for operation of the handpiece. The connector links the handle to the working head, supporting multi-angle rotation to facilitate adjustment of the operating direction by the dentist. The working head directly contacts bone tissue for tooth preparation or drilling. Furthermore, to enable navigation, the implant handpiece also needs to be equipped with positioning markers to work in conjunction with a binocular navigation system for accurate positioning.

[0005] However, existing implantation phone calibration devices used for preoperative calibration of implantation phones suffer from problems such as cumbersome structure and limited functionality, and the industry urgently needs to propose better solutions. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide a device for calibrating a planting mobile phone, which integrates the axial, length and diameter calibration functions of the working head on the planting mobile phone into one device, and has the advantages of simple structure and complete functions.

[0007] The technical solution adopted by this utility model to solve the technical problem is as follows:

[0008] A planting mobile phone calibration device, comprising:

[0009] The calibration body is a square block structure;

[0011] A marker carrier plate is fixedly disposed at the center of the upper surface of the calibration body, and at least four optical markers are disposed on the marker carrier plate;

[0012] A length calibration groove is disposed on the upper surface of the calibration body. A first vertical calibration sidewall, a second vertical calibration sidewall, and a horizontal calibration bottom wall are formed within the length calibration groove. The first and second vertical calibration sidewalls are arranged vertically, and the horizontal calibration bottom wall is arranged horizontally. The first and second vertical calibration sidewalls intersect to form an angle. The first and second vertical calibration sidewalls form a calibration entrance on their opposite sides, and the first and second length calibration sidewalls form a shaft diameter calibration angle on their intersecting side.

[0013] Compared with existing technologies, the beneficial effects of this technical solution are: by integrating structures such as direction calibration posts and length calibration slots on the calibration body, it is possible to comprehensively calibrate the axial direction, length and diameter of the working head on the implantation mobile phone, which has the advantages of simple structure and complete functions.

[0014] Furthermore, the marking support plate includes a vertical calibration support plate and two horizontal calibration support plates.

[0016] The advantages of adopting the above scheme are: setting up a vertical calibration support plate and two horizontal calibration support plates, and using the optical marks on the calibration support plate in conjunction with the binocular navigation device to achieve real-time positioning of the planting mobile phone calibration device, which is applicable to vertical planting mobile phones and conventional planting mobile phones; and placing the protruding vertical calibration support plate in the center, and placing the two horizontal calibration support plates on both sides of the vertical calibration support plate respectively, makes the structural setting of this device more scientific and reasonable.

[0017] Furthermore, the upper surface of the calibration body is provided with three sleeve recesses, and the lower surface of the calibration body is provided with three threaded mounting through holes. The threaded mounting through holes are provided with bearing plate fixing bolts, and the sleeve recesses and the threaded mounting through holes correspond one-to-one; the lower surfaces of the vertical calibration bearing plate and the horizontal calibration bearing plate are both provided with internal threaded holes.

[0018] The vertical calibration support plate and the horizontal calibration support plate are respectively disposed in the three sleeve recesses. The support plate fixing bolt passes through the threaded mounting through hole and is threadedly connected to the internal threaded hole on the vertical calibration support plate or the horizontal calibration support plate, thereby fixing the vertical calibration support plate or the horizontal calibration support plate in the corresponding sleeve recess.

[0019] The beneficial effects of adopting the above scheme are: the sleeve recess and the threaded mounting through hole are connected, and after the bearing plate fixing bolt passes through the threaded mounting through hole, the vertical calibration bearing plate or horizontal calibration bearing plate that is pre-fitted in the sleeve recess is fixedly connected through the internal thread hole below it, thereby realizing the installation and fixing of the vertical calibration bearing plate or horizontal calibration bearing plate.

[0020] Furthermore, the upper surfaces of the two horizontal calibration bearing plates are located on different horizontal planes.

[0021] The advantages of adopting the above solution are: it can adapt to vertical planting mobile phones of different sizes, and facilitates the binocular navigation device set on the vertical planting mobile phone to more clearly collect real-time images of the optical marks on the horizontal calibration carrier plate.

[0022] Furthermore, the calibration body is provided with a ball-head calibration groove and a cone-head calibration groove.

[0023] The beneficial effects of adopting the above scheme are: depending on the needs of clinical application, the implantation handpiece can be equipped with a conical drill or a ball-head drill, and the calibration body is equipped with a ball-head calibration groove and a conical calibration groove, which facilitates the calibration of the conical drill or ball-head drill that may be set on the implantation handpiece.

[0024] Furthermore, the upper surface of the calibration body is recessed downward to form a spherical cone calibration platform. The plane of the spherical cone calibration platform is located below the plane of the upper surface of the calibration body. The spherical calibration groove and the cone calibration groove are disposed on the spherical cone calibration platform.

[0025] The beneficial effect of adopting the above scheme is that by forming a spherical cone calibration platform by recessing the upper surface of the calibration body downwards, and setting the spherical cone calibration groove and the cone calibration groove on the spherical cone calibration platform, it is possible to prevent the planting mobile phone from covering the optical mark on the mark carrier plate when calibrating the cone drill or the ball drill.

[0026] Furthermore, the direction calibration post, the ball head calibration groove, and the cone head calibration groove are disposed on one side of the marking support plate, and the length calibration groove is disposed on the other side of the marking support plate.

[0027] The beneficial effects of adopting the above scheme are: a direction calibration post, a ball head calibration groove, and a cone head calibration groove are set on one side of the positioning mark bearing plate, and a length calibration groove is set on the other side, making full use of the limited space to integrate more functional modules, making the structural setting more scientific and reasonable.

[0028] Furthermore, three length calibration slots are provided, and the horizontal calibration bottom walls on the three length calibration slots are located on different horizontal planes.

[0029] The advantages of adopting the above solution are: it can adapt to vertical planting mobile phones of different sizes, and facilitates the binocular navigation device set on the vertical planting mobile phone to more clearly collect real-time images of the optical marks on the horizontal calibration carrier plate.

[0030] Furthermore, the optical mark includes a first triangular region, a second triangular region, a first sector region, and a second sector region formed on the mark carrier plate.

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.

[0031] The beneficial effect of adopting the above scheme is that it makes the image recognition of optical marks on the binocular navigation device more accurate.

[0032] Furthermore, the calibration body is an aluminum alloy structure, and the direction calibration post and the marking support plate are ceramic structures.

[0033] The advantages of adopting the above scheme are: using an aluminum alloy structure as the calibration body can reduce the weight of the device while increasing its strength; using a ceramic structure as the direction calibration post and the mark support plate can effectively prevent the direction calibration post and the mark support plate from bending and deforming, ensuring accurate and reliable calibration results.

[0042] To make the objectives, technical solutions, and advantages of this utility model clearer and more explicit, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0043] In the description of this utility model, it should be understood that the terms "center," "upper," "lower," "front," "rear," "left," and "right," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0044] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. When a component is referred to as being "fixed to" or "set on" another element, it can be directly on the other component or there may be an intervening component. When a component is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intervening component. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0045] When patients experience tooth loss, it can affect their eating and daily social interactions. The most direct and effective treatment is dental implants. Replacing missing teeth with implants has an immediate and significant effect on improving the oral and digestive health of patients with missing teeth, as well as enhancing their quality of life.

[0046] Dental implant surgery demands extremely high precision. A binocular navigation system can be used for real-time intraoperative navigation to ensure the most suitable implantation plan is implemented based on the patient's oral condition. The process roughly involves the binocular navigation system acquiring positioning markers on the implant handpiece to determine its real-time position, which is then compared with the predetermined implantation plan to provide real-time navigation for the handpiece.

[0047] An implant handpiece comprises a grip handle, a connector, and a working head. The grip handle is used to hold and hold the implant body, allowing for operation of the handpiece. The connector links the handle to the working head, supporting multi-angle rotation to facilitate adjustment of the operating direction by the dentist. The working head directly contacts bone tissue for tooth preparation or drilling. Furthermore, to enable navigation, the implant handpiece also needs to be equipped with positioning markers to work in conjunction with a binocular navigation system for accurate positioning.

[0048] The purpose of calibration is to unify the three-dimensional coordinate system of the implantable phone and the three-dimensional coordinate system of the binocular navigation system, thereby determining the real-time pose of the implantable phone under the binocular navigation system. The calibration process generally requires the use of the implantable phone, a calibration device, and the binocular navigation system. However, current implantable phone calibration devices used for preoperative calibration suffer from problems such as cumbersome structure and limited functionality, necessitating better solutions from the industry.

[0049] like Figure 1 , Figure 2 and Figure 3 As shown, in order to solve the above problems, this utility model provides a planting mobile phone calibration device, including a calibration body 1, a direction calibration column 2, an identification bearing plate 3, and a length calibration groove 5.

[0050] The calibration body 1 is a square block structure with an upper surface and a lower surface. The direction calibration post 2 is vertically disposed on the upper surface of the calibration body 1. The mark carrier plate 3 is fixedly disposed at the center of the upper surface of the calibration body 1, and at least four optical marks 4 are disposed on the mark carrier plate 3. Since more than one mark carrier plate 3 can be disposed when implementing this technical solution, the "center" mentioned here refers to the center of the length of the calibration body 1. A single calibration body 1 may not be located at the geometric center, but multiple mark carrier plates 3 as a whole are located at the geometric midpoint of the upper surface of the calibration body 1.

[0051] The length calibration groove 5 is disposed on the upper surface of the calibration body 1. A first vertical calibration sidewall 501, a second vertical calibration sidewall 502, and a horizontal calibration bottom wall 503 are formed within the length calibration groove 5. The first vertical calibration sidewall 501 and the second vertical calibration sidewall 502 are arranged vertically, and the horizontal calibration bottom wall 503 is arranged horizontally. The first vertical calibration sidewall 501 and the second vertical calibration sidewall 502 intersect to form an angle. A calibration inlet 504 is formed on the opposite side of the first vertical calibration sidewall 501 and the second vertical calibration sidewall 502. A shaft diameter calibration angle 505 is formed on the other intersecting side of the first length calibration sidewall and the second length calibration sidewall. Simply put, the length calibration groove 5 can be understood as a triangular groove formed on the calibration body 1.

[0052] During calibration, the binocular navigator is fixed to the implantation handpiece, the working head is removed from the handpiece, and the handpiece is then fitted onto the orientation calibration post 2. Given the known relative positions of the calibration body 1, orientation calibration post 2, marker support plate 3, and length calibration slot 5 on the handpiece calibration device, the binocular navigator simultaneously acquires the real-time pose of the calibration plate on the handpiece and the marker support plate 3. The axial direction of the handpiece can then be determined by the real-time pose of the calibration plate. After axial calibration, the working head is inserted and placed against the horizontal calibration bottom wall 503 on the length calibration slot 5. Given the known relative positions of the calibration body 1, orientation calibration post 2, marker support plate 3, and length calibration slot 5 on the handpiece calibration device, the length of the working head can be determined by combining this with the axial direction of the handpiece, thus completing the length calibration. When diameter calibration is required, the angle formed between the first vertical calibration sidewall 501 and the second vertical calibration sidewall 502 in the length calibration groove 5 is used to control the working head so that its two sides are respectively in close contact with the first vertical calibration sidewall 501 and the second vertical calibration sidewall 502. At this time, the real-time pose of the calibration plate on the implant handpiece is acquired, and the point between the first vertical calibration sidewall 501 and the second vertical calibration sidewall 502 of the working head can be determined, thereby completing the diameter calibration of the working head. It should be noted that this technical solution only improves the structure of the calibration device based on problems found in clinical practice. The above data processing method is existing technology in the field of dental implants and is known and clear to the industry. This technical solution does not improve the above data processing process.

[0053] Based on the above structure, by integrating the direction calibration post 2 and length calibration groove 5 on the calibration body 1, the axial direction, length and diameter of the working head on the implantation mobile phone can be calibrated more comprehensively, which has the advantages of simple structure and complete functions.

[0054] like Figure 1 , Figure 2 and Figure 3As shown, preferably, the marking support plate 3 includes a vertical calibration support plate 301 and two horizontal calibration support plates 302. The vertical calibration support plate 301 is disposed in the center of the upper surface of the calibration body 1, and the two horizontal calibration support plates 302 are respectively disposed on both sides of the vertical calibration support plate 301. The optical mark 4 is disposed on both opposite sides of the vertical calibration support plate 301, and the optical mark 4 is disposed on the upper surface of the horizontal calibration support plate 302.

[0055] As described above, more than one marking support plate 3 can be provided. In this embodiment, three marking support plates 3 are provided, including one vertical marking support plate 301 and two horizontal marking support plates 302. The vertical marking support plate 301 protrudes from the marking body 1, while the horizontal marking support plates 302 are flush with or recessed into the marking body 1. The vertical marking support plate 301 is located at the center of the upper surface of the marking body 1, meaning that the protruding vertical marking support plate 301 is located at the geometric midpoint of the upper surface of the marking body 1. Correspondingly, the two horizontal marking support plates 302 are respectively provided on both sides of the vertical marking support plate 301. The vertical marking support plate 301 and the two horizontal marking support plates 302 are a whole, located at the center of the upper surface of the marking body 1.

[0056] Based on the above structure, a vertical calibration support plate 301 and two horizontal calibration support plates 302 are provided. The optical mark 4 on the calibration support plate 3 is used in conjunction with the binocular navigator to realize the real-time positioning of the planting mobile phone calibration device, which can be applied to vertical planting mobile phones and conventional planting mobile phones. By placing the protruding vertical calibration support plate 301 in the center and the two horizontal calibration support plates 302 on both sides of the vertical calibration support plate 301, the structural setting of this device is more scientific and reasonable.

[0057] like Figure 2 and Figure 3 As shown, the upper surface of the calibration body 1 is provided with three sleeve recesses 101, and the lower surface of the calibration body 1 is provided with three threaded mounting through holes. A bearing plate fixing bolt is installed in each of the threaded mounting through holes. The sleeve recesses 101 and the threaded mounting through holes correspond one-to-one. The lower surfaces of the vertical calibration bearing plate 301 and the horizontal calibration bearing plate 302 are both provided with internal threaded holes. The vertical calibration bearing plate 301 and the horizontal calibration bearing plate 302 are correspondingly disposed within the three sleeve recesses 101. The bearing plate fixing bolt passes through the threaded mounting through holes and is threadedly connected to the internal threaded holes on the vertical calibration bearing plate 301 or the horizontal calibration bearing plate 302, thereby fixing the vertical calibration bearing plate 301 or the horizontal calibration bearing plate 302 within the corresponding sleeve recesses 101.

[0058] There are three recessed parts 101, and correspondingly, there are three threaded mounting through holes, one for a vertical calibration support plate 301 and two for a horizontal calibration support plate 302. Taking the vertical calibration support plate 301 as an example, the installation and fixing process is as follows: After the vertical calibration support plate 301 is inserted into the recessed part 101, its internal threaded hole corresponds to the threaded mounting through hole. Then, the support plate fixing bolt is inserted into the threaded mounting through hole, and rotating the support plate fixing bolt will engage with the internal threaded hole, thereby fixing the vertical calibration support plate 301 to the calibration body 1.

[0059] Based on the above structure, the sleeve recess 101 is connected to the threaded mounting through hole. After the bearing plate fixing bolt passes through the threaded mounting through hole, the vertical calibration bearing plate 301 or the horizontal calibration bearing plate 302, which is pre-fitted in the sleeve recess 101, is fixedly connected through the internal thread hole below it, thereby realizing the installation and fixing of the vertical calibration bearing plate 301 or the horizontal calibration bearing plate 302.

[0060] Before calibration, the binocular navigation device needs to be fixed to the implant handpiece. In the prior art, clinically used implant handpieces include vertical implant handpieces and conventional implant handpieces. The former has its working head and body coaxially arranged, while the latter has its working head and body forming a certain angle. When calibrating a vertical implant handpiece, the binocular navigation device on the vertical implant handpiece faces the upper surface of the calibration body 1, thus aligning directly with the horizontal calibration support plate 302. Since vertical implant handpieces may vary in size and length, considering the depth-of-field limitations of the binocular navigation device, the upper surfaces of the two horizontal calibration support plates 302 are located on different horizontal planes, making them suitable for vertical implant handpieces of different sizes.

[0061] Based on the above structure, it can adapt to vertical planting mobile phones of different sizes, and facilitates the binocular navigation device set on the vertical planting mobile phone to more clearly collect the real-time image of the optical mark 4 on the horizontal calibration carrier plate 302.

[0062] like Figure 1 , Figure 2 and Figure 3 As shown, the calibration body 1 is provided with a ball-head calibration groove 102 and a cone-head calibration groove 103. Depending on clinical application needs, the working head of the implantation handpiece includes a cone-head drill or a ball-head drill. The ball-head calibration groove 102 and the cone-head calibration groove 103 on the calibration body 1 facilitate the calibration of the cone-head drill or ball-head drill that may be installed on the implantation handpiece. The cone-head calibration groove 103 is used to calibrate the cone-head drill of the implantation handpiece, and the ball-head calibration groove 102 is used to calibrate the ball-head drill of the implantation handpiece.

[0063] When calibrating the ball-head drill of the implantation handpiece, the ball-head drill is installed and fixed on the implantation handpiece, and then the implantation handpiece controls the ball-head drill to abut against the ball-head calibration groove 102. Since the positional relationship between the ball-head calibration groove 102 and the calibration body 1 is known, the calibration operation of the ball-head drill of the implantation handpiece can be completed based on the data collected by the binocular navigation system. When calibrating the conical drill, the conical drill is installed and fixed on the implantation handpiece, and the implantation handpiece controls the conical drill to abut against the conical calibration groove 103. Since the positional relationship between the conical recess and the calibration body 1 is known, the calibration operation of the conical drill of the implantation handpiece can be completed based on the data collected by the binocular navigation system. Based on the above structure, the calibration body 1 is provided with a ball-head calibration groove 102 and a conical calibration groove 103, which can perform comprehensive calibration of the implantation handpiece. It meets multiple calibration needs with a simple structure 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.

[0064] like Figure 1 , Figure 2 and Figure 3 As shown, preferably, the upper surface of the calibration body 1 is recessed downward to form a spherical cone calibration platform 104, the plane of the spherical cone calibration platform 104 is located below the plane of the upper surface of the calibration body 1, and the spherical calibration groove 102 and the cone calibration groove 103 are disposed on the spherical cone calibration platform 104.

[0065] Based on the above structure, a spherical cone calibration platform 104 is formed by recessing the upper surface of the calibration body 1, and a spherical cone calibration groove 102 and a cone calibration groove 103 are provided on the spherical cone calibration platform 104 to prevent the planting mobile phone from covering the optical mark 4 on the mark carrier plate 3 when calibrating the cone drill or the ball drill.

[0066] like Figure 1 , Figure 2 and Figure 3 As shown, preferably, the direction calibration post 2, the ball head calibration groove 102 and the cone head calibration groove 103 are disposed on one side of the marking support plate 3, and the length calibration groove 5 is disposed on the other side of the marking support plate 3.

[0067] Based on the above structure, a direction calibration post 2, a ball head calibration groove 102, and a cone head calibration groove 103 are provided on one side of the positioning mark bearing plate 3, and a length calibration groove 5 is provided on the other side. This makes full use of the limited space to integrate more functional modules, making the structural design more scientific and reasonable.

[0068] like Figure 1 , Figure 2 and Figure 3 As shown, preferably, three length calibration slots 5 are provided, and the horizontal calibration bottom walls 503 on the three length calibration slots 5 are located on different horizontal planes. Based on the above structure, it can adapt to vertical planting mobile phones of different sizes, and facilitate the binocular navigation device set on the vertical planting mobile phone to more clearly collect the real-time image of the optical mark 4 on the horizontal calibration support plate 302.

[0069] Preferably, the optical mark 4 includes a first triangular region, a second triangular region, a first sector-shaped region, and a second sector-shaped region formed on the mark carrier plate 3. The first triangular region, the second triangular region, the first sector-shaped region, and the second sector-shaped region share a common vertex. The first triangular region and the second triangular region are spaced apart, and the first sector-shaped region and the second sector-shaped region are spaced apart. The first triangular region and the second triangular region are white areas, and the first sector-shaped region and the second sector-shaped region are black areas. By forming the optical mark 4 with the first triangular region, the second triangular region, the first sector-shaped region, and the second sector-shaped region, and by providing both white and black areas, the image recognition of the optical mark 4 on the binocular navigation device can be improved.

[0070] Specifically, the calibration body 1 is an aluminum alloy structure, while the direction calibration post 2 and the marking support plate 3 are ceramic structures. Using an aluminum alloy structure for the calibration body 1 reduces the weight of the device while increasing its strength; using ceramic structures for the direction calibration post 2 and the marking support plate 3 effectively prevents bending deformation, ensuring accurate and reliable calibration results.

[0071] 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.
