Description

Technical Field

[0001] This utility model relates to the field of medical equipment technology, and to a combined oral treatment instrument calibration device for calibrating the maxillary sinus lift tool before performing maxillary sinus lift surgery. Background Technology

[0002] The maxillary sinus is a hollow structure located above the posterior maxillary teeth. Its location and shape vary from person to person. In cases of long-term tooth loss, alveolar bone resorption, or maxillary sinus pneumatization, the remaining bone height may be insufficient to directly accommodate a standard-length implant. In such cases, a maxillary sinus lift is necessary.

[0003] The purpose of maxillary sinus lift surgery is to increase bone height, thereby providing stable support for implants. Through internal or external lift, the maxillary sinus floor mucosa is raised, creating new bone cavity space, which is then filled with bone graft materials such as artificial bone powder or autologous bone blocks. This process increases vertical bone height, providing sufficient osseointegration length for the implant and ensuring its stability.

[0004] Maxillary sinus lift surgery relies on a maxillary sinus lift tool. During the procedure, it is crucial to avoid damaging important structures such as the maxillary sinus floor mucosa, nasal mucosa, and maxillary artery. The tool design must be adapted to operation in confined spaces. Because the morphology of the maxillary sinus varies from person to person, there are numerous shapes and sizes of maxillary sinus lift tools available. Often, it is necessary to custom-make different maxillary sinus lift tools based on the patient's specific situation.

[0005] During maxillary sinus lift surgery, optical navigation devices, operating reference boards, and oral reference boards are typically used to assist in intraoperative navigation to ensure operational precision. How to perform pre-navigation calibration for maxillary sinus lift tools with numerous shapes and sizes to achieve high-precision navigation is a technical problem that urgently needs to be solved in the industry. Summary of the Invention

[0006] The technical problem to be solved by this utility model is to provide a combined oral treatment instrument calibration device that can perform pre-navigation calibration of maxillary sinus lifting tools of various shapes and sizes before performing maxillary sinus lifting surgery, thereby providing a strong guarantee for improving surgical accuracy.

[0007] The technical solution adopted by this utility model to solve the technical problem is as follows: A combined oral treatment instrument calibration device includes: The calibration block body has multiple calibration grooves on its upper surface, and the shape of the calibration grooves matches the shape of the working tip of the maxillary sinus lifter to be calibrated. The identification block body includes a top support plate, a first side support plate, a second side support plate, a third side support plate, and a fourth side support plate. The top support plate has a square plate structure. The first side support plate, the second side support plate, the third side support plate, and the fourth side support plate are disposed on the four sides of the top support plate. The upper surface of the top support plate is provided with multiple optical marking components. The calibration block connecting assembly and the identification block connecting assembly are provided. The calibration block connecting assembly is disposed on the side of the calibration block body, and the identification block connecting assembly is disposed on the side of the identification block body. The identification block body is detachably fixed to the calibration block body through the cooperation of the calibration block connecting assembly and the identification block connecting assembly.

[0008] Compared with existing technologies, the beneficial effects of this technical solution are: after developing corresponding calibration block bodies for maxillary sinus lift tools with numerous shapes and sizes, the identification block body and the calibration block body can be detachably connected through the cooperation of the calibration block connecting component and the identification block connecting component. This enables pre-navigation calibration before performing maxillary sinus lift surgery, providing a strong guarantee for improving surgical accuracy.

[0009] Furthermore, a partition support plate is provided on the identification block body, and the partition support plate is disposed between the first side support plate and the third side support plate; A first cavity is formed between the first side support plate and the partition support plate, and a second cavity is formed between the third side support plate and the partition support plate. Bottom openings are formed on the first cavity and the second cavity. The bottom opening of the second cavity is provided with multiple cavity support bars, which are spaced apart from each other.

[0010] The beneficial effects of adopting the above scheme are: the first cavity and the second cavity are formed by the first side support plate, the third side support plate and the partition support plate, and multiple cavity support bars are set at the bottom opening of the second cavity. The bottom opening of the first cavity is not set with other components, which makes it convenient for the operator's fingers to contact the partition support plate in the first cavity during the calibration process, making the grip more secure.

[0011] Furthermore, the calibration block connecting component is a protruding elongated portion disposed on the side of the calibration block body, and the identification block connecting component is an insertion strip-shaped groove disposed on the side of the identification block body, the insertion strip-shaped groove opening towards the calibration block body; The length of the protruding strip is less than the length of the insertion groove. The identification block body is detachably fixed to the calibration block body by inserting the protruding strip into the insertion groove.

[0012] The advantages of adopting the above scheme are: the identification block body and the calibration block body can be detachably connected by interlocking the protruding long strip and the interlocking strip groove, which not only improves the connection and fixation effect, but also facilitates replacement operation.

[0013] Furthermore, the side of the calibration block body is provided with an auxiliary insertion protrusion, and the side of the identification block body is provided with an auxiliary insertion recess, the auxiliary insertion recess opening in the direction parallel to the extension direction of the first side support plate and the third side support plate. When the calibration block body is fixedly connected to the identification block body, the auxiliary insertion protrusion is inserted into the auxiliary insertion recess.

[0014] The beneficial effects of the above scheme are as follows: an auxiliary insertion recess is provided on the basis of the insertion strip groove, and the insertion strip groove opens towards the calibration block body, while the auxiliary insertion recess opens towards the extension direction parallel to the first side support plate and the third side support plate. When the calibration block body and the identification block body are connected to each other, the protruding strip is inserted into the insertion strip groove in one direction, and then the auxiliary insertion protrusion is inserted into the auxiliary insertion recess from the other side, thus fixing the calibration block body and the identification block body from two directions, which can effectively improve the fixing effect.

[0015] Furthermore, the auxiliary insertion protrusion includes an insertion connecting plate and an insertion cylinder. The insertion cylinder is fixedly mounted on the calibration block body via the insertion connecting plate. The insertion connecting plate is parallel to the top support plate, and the central axis of the insertion cylinder is aligned with the orientation of the auxiliary insertion recess. The auxiliary insertion recess includes a cylindrical recess and an elongated recess. The outer diameter of the cylindrical recess is larger than the width of the elongated recess. When the identification block body is fixedly mounted on the calibration block body, the insertion cylinder is sleeved in the cylindrical recess, and the insertion connecting plate is sleeved in the elongated recess.

[0016] The beneficial effects of the above scheme are: the auxiliary insertion protrusion uses the insertion connecting plate and the insertion cylinder to form a size difference, and the auxiliary insertion recess uses the cylindrical recess and the elongated recess to form a size difference. When the auxiliary insertion protrusion and the auxiliary insertion recess are inserted into each other, the size difference prevents the calibration block body and the identification block body from separating due to external force.

[0017] Furthermore, an internal threaded connection portion is provided on the side of the calibration block body, and the internal threaded connection portion and the auxiliary insertion protrusion portion are provided on opposite sides of the side of the calibration block body. The side of the identification block body is also provided with a threaded connection through hole, and a locking bolt is provided in the threaded connection through hole. The threaded connection through hole and the auxiliary insertion recess are respectively provided on opposite sides of the side of the identification block body.

[0018] The beneficial effect of adopting the above scheme is that the calibration block body and the identification block body are connected and fixed to each other through the threaded engagement between the locking bolt and the internal thread connection part, which facilitates the improvement of the structural stability of the device.

[0019] Furthermore, the lower surface of the calibration block body is recessed inward to form a back groove.

[0020] The beneficial effects of adopting the above scheme are: the function of the calibration block body is to perform pre-navigation calibration of the maxillary sinus lifting tool with matching shape and size. The inward concavity on the lower surface of the calibration block body forms a back groove, which can reduce the mass of the calibration block body while ensuring the calibration operation requirements.

[0021] Furthermore, the top support plate is provided with a first protruding strip, a second protruding strip, a third protruding strip, and a fourth protruding strip, which are sequentially connected end to end on the upper surface edge of the top support plate.

[0022] The beneficial effect of adopting the above scheme is that the first, second, third and fourth protruding strips form a protective effect on the upper surface of the top support plate, preventing accidental operation from causing frictional damage to the optical marking components.

[0023] Furthermore, the optical marking assembly includes an optical marking sheet and an optical marking pattern, the optical marking pattern being formed on the optical marking sheet, and the optical marking sheet being affixed to the upper surface of the top support plate; The optical marking pattern is divided into a first fan-shaped marking area, a second fan-shaped marking area, a first triangular marking area, and a second triangular marking area. The first fan-shaped marking area and the second fan-shaped marking area are arranged opposite to each other, and the first triangular marking area and the second triangular marking area are arranged opposite to each other.

[0024] The beneficial effect of adopting the above scheme is that the optical marking pattern composed of the first sector marking area, the second sector marking area, the first triangle marking area, and the second triangle marking area on the optical marking sheet facilitates the optical navigation device to identify the optical marking components.

[0025] Furthermore, the calibration block body is a one-piece molded aluminum alloy structure, and the identification block body is a one-piece molded aluminum alloy structure.

[0026] The advantages of adopting the above scheme are: using an aluminum alloy structure as the calibration block body and the identification block body can enhance the strength of the device while reducing its weight. Attached Figure Description

[0035] The maxillary sinus is a hollow structure located above the posterior maxillary teeth. Its location and shape vary from person to person. In cases of long-term tooth loss, alveolar bone resorption, or maxillary sinus pneumatization, the remaining bone height may be insufficient to directly accommodate a standard-length implant. In such cases, a maxillary sinus lift is necessary.

[0036] The purpose of maxillary sinus lift surgery is to increase bone height, thereby providing stable support for implants. Through internal or external lift, the maxillary sinus floor mucosa is raised, creating new bone cavity space, which is then filled with bone graft materials such as artificial bone powder or autologous bone blocks. This process increases vertical bone height, providing sufficient osseointegration length for the implant and ensuring its stability.

[0037] Maxillary sinus lift surgery relies on a maxillary sinus lift tool. During the procedure, it is crucial to avoid damaging important structures such as the maxillary sinus floor mucosa, nasal mucosa, and maxillary artery. The tool design must be adapted to operation in confined spaces. Because the morphology of the maxillary sinus varies from person to person, there are numerous shapes and sizes of maxillary sinus lift tools available. Often, it is necessary to custom-make different maxillary sinus lift tools based on the patient's specific situation.

[0038] During maxillary sinus lift surgery, optical navigation systems, manipulative reference boards, and oral reference boards are typically used to assist in intraoperative navigation and ensure operational precision. How to perform pre-navigation calibration for maxillary sinus lift tools with numerous shapes and sizes is a technical problem that urgently needs to be solved in the industry.

[0039] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, to solve the above problems, this utility model provides a combined oral treatment instrument calibration device, mainly including a calibration block body 1 and an identification block body 2, which are used in conjunction with the maxillary sinus lifter 3, the working tip 4, and the operation reference plate 5 during the calibration process. The function of the calibration block body 1 is to nest the working tip 4 of the maxillary sinus lifter 3 for calibration, and the function of the identification block body 2 is to cooperate with the optical navigation device to determine the real-time position and posture.

[0040] The upper surface of the calibration block body 1 is provided with multiple calibration grooves 101. These grooves 101 are formed by conforming the shape of the working tip 4, and their shape matches the shape of the working tip 4 of the maxillary sinus lifter 3 to be calibrated. Many different types of working tips 4 are used in maxillary sinus lift procedures, including straight tips, curved tips, and thumbtack-shaped tips. The function, usage, shape, and size of these working tips 4 are existing technology for those skilled in the art. In this technical solution, the multiple calibration grooves 101 on the calibration block body 1 are specially designed according to the working tips 4 required for different applications. During the implementation of this technical solution, the calibration grooves 101 can be adaptively adjusted so that when the working tip 4 is placed in the corresponding calibration groove 101, the working tip 4 and the calibration groove 101 overlap as completely as possible.

[0041] The identification block body 2 includes a top support plate 201, a first side support plate 202, a second side support plate 203, a third side support plate 204, and a fourth side support plate 205. The top support plate 201 is a square plate structure. The first side support plate 202, the second side support plate 203, the third side support plate 204, and the fourth side support plate 205 are disposed on the four sides of the top support plate 201. Multiple optical marker components 206 are disposed on the upper surface of the top support plate 201. By setting the first side support plate 202, the second side support plate 203, the third side support plate 204, and the fourth side support plate 205 on the top support plate 201, and then setting multiple optical marker components 206 on the upper surface of the top support plate 201, when the optical navigator receives the light reflected back from the multiple optical marker components 206, it can determine the real-time pose of the mutually fixed calibration block body 1 and the identification block body 2 through these rays.

[0042] Based on the calibration block body 1 and the identification block body 2, the two are fixedly connected by a calibration block connecting component and an identification block connecting component. The calibration block connecting component is disposed on the side of the calibration block body 1, and the identification block connecting component is disposed on the side of the identification block body 2. The identification block body 2 is detachably fixed to the calibration block body 1 through the cooperation of the calibration block connecting component and the identification block connecting component.

[0043] During installation, the calibration block connecting component and the identification block connecting component are connected and cooperated to form the overall structure of the combined oral treatment instrument calibration device by connecting the calibration block body 1 and the identification block body 2. In this combined oral treatment instrument calibration device, the relative positions of multiple optical marking components 206 and multiple calibration slots 101 are known.

[0044] Before calibration, the maxillary sinus lifter 3 and the operation reference plate 5 are fixedly connected, and the multiple optical marker components 206 in the calibration device of this combined oral treatment instrument are placed within the image acquisition range of the optical navigator. During calibration, the working tip 4 is placed in the calibration slot 101, and the optical navigator is controlled to acquire the real-time poses of the optical marker components 206 and the operation reference plate 5. On the one hand, since the relative positions of the multiple optical marker components 206 and the multiple calibration slots 101 in the combined oral treatment instrument calibration device are known, the working tip 4 and the calibration slot 101 are completely overlapped when the working tip 4 is placed in the calibration slot 101. At this time, the pose of the calibration slot 101 on the calibration block body 1 can be used as the pose of the working tip 4. On the other hand, since the real-time poses of the multiple optical marker components 206 and the operation reference plate 5 on the identification block body 2 are known in the optical navigator during this process, the pose of the working tip 4 can be characterized by the operation reference plate 5 to complete the calibration. It should be noted that the above calibration process and principle are known existing technologies.

[0045] Based on the above structure and operation process, after developing a corresponding calibration block body 1 for maxillary sinus lift tools with numerous shapes and sizes, the identification block body 2 and the calibration block body 1 are detachably connected through the cooperation of the calibration block connecting component and the identification block connecting component. This allows for pre-navigation calibration before performing maxillary sinus lift surgery, providing a strong guarantee for improving surgical accuracy.

[0046] like Figure 4 As shown, preferably, the identification block body 2 is provided with a partition support plate 207, which is disposed between the first side support plate 202 and the third side support plate 204.

[0047] A first side support plate 202, a second side support plate 203, a third side support plate 204, and a fourth side support plate 205 are disposed on a top support plate 201. A space is formed between the first side support plate 202, the second side support plate 203, the third side support plate 204, the fourth side support plate 205, and the top support plate 201. A partition support plate 207 is then disposed on this space. A first cavity is formed between the first side support plate 202 and the partition support plate 207, and a second cavity is formed between the third side support plate 204 and the partition support plate 207. Bottom openings are formed on both the first cavity and the second cavity. A plurality of cavity support strips 208 are disposed at the bottom opening of the second cavity, and the plurality of cavity support strips 208 are spaced apart from each other.

[0048] During calibration, the operator holds the device with their left hand. Multiple cavity support bars 208 are provided at the bottom opening of the second cavity, spaced apart from each other. When holding the device, the operator's left-hand fingers rest against the cavity support bars 208, while the fingertips engage with the partition support plate 207 inside the second cavity, providing a better point of leverage.

[0049] Based on the above structure, a first cavity and a second cavity are formed by the first side support plate 202, the third side support plate 204 and the partition support plate 207. Multiple cavity support bars 208 are provided at the bottom opening of the first cavity, and no other components are provided at the bottom opening of the second cavity. This makes it convenient for the operator's fingers to contact the partition support plate 207 in the first cavity during the calibration process, making the grip more secure.

[0050] like Figure 3 and Figure 4 As shown, preferably, the calibration block connecting assembly is a protruding elongated strip 102 disposed on the side of the calibration block body 1, and the identification block connecting assembly is an insertion strip-shaped groove 209 disposed on the side of the identification block body 2, the insertion strip-shaped groove 209 opening towards the calibration block body 1. That is, the insertion strip-shaped groove 209 is disposed on the side of the identification block body 2 near the calibration block body 1, making it easier for the identification block body 2 and the calibration block body 1 to be inserted into each other.

[0051] To further facilitate insertion, the length of the protruding elongated portion 102 is less than the length of the insertion strip groove 209. The identification block body 2 is detachably fixed to the calibration block body 1 by inserting the protruding elongated portion 102 into the insertion strip groove 209.

[0052] Based on the above technical solution, the identification block body 2 and the calibration block body 1 are detachably connected by interlocking the protruding elongated part 102 and the interlocking strip groove 209. This not only improves the connection and fixation effect but also facilitates replacement.

[0053] like Figure 3 and Figure 4 As shown, preferably, the side of the calibration block body 1 is further provided with an auxiliary insertion protrusion 103, and the side of the identification block body 2 is further provided with an auxiliary insertion recess 210, the auxiliary insertion recess 210 opening toward the extension direction parallel to the first side support plate 202 and the third side support plate 204.

[0054] When the calibration block body 1 is fixedly connected to the identification block body 2, in addition to the protruding elongated part 102 being inserted into the insertion strip groove 209, the auxiliary insertion protrusion 103 is inserted into the auxiliary insertion recess 210.

[0055] Based on the above structure, an auxiliary insertion recess 210 is provided on the basis of the insertion strip groove 209. The insertion strip groove 209 opens towards the calibration block body 1, and the auxiliary insertion recess 210 opens towards the extension direction parallel to the first side support plate 202 and the third side support plate 204. When the calibration block body 1 and the identification block body 2 are connected to each other, the protruding elongated part 102 is inserted into the insertion strip groove 209 in one direction, and the auxiliary insertion protrusion 103 is inserted into the auxiliary insertion recess 210 from the other side. The calibration block body 1 and the identification block body 2 are fixed from two directions, which can effectively improve the fixing effect.

[0056] like Figure 3 and Figure 4 As shown, preferably, the auxiliary insertion protrusion 103 includes an insertion connecting plate and an insertion cylinder. The insertion cylinder is fixedly mounted on the calibration block body 1 via the insertion connecting plate. The insertion connecting plate is parallel to the top support plate 201, and the extension direction of the central axis of the insertion cylinder is parallel to the extension directions of the first side support plate 202 and the third side support plate 204. The outer diameter of the insertion cylinder is larger than the outer diameter of the insertion connecting plate. Correspondingly, the auxiliary insertion recess 210 includes a cylindrical recess and an elongated recess. The outer diameter of the cylindrical recess is larger than the width of the elongated recess. When the identification block body 2 is fixedly mounted on the calibration block body 1, the insertion cylinder is sleeved within the cylindrical recess, and the insertion connecting plate is sleeved within the elongated recess.

[0057] The plug-in connection plate is a connection structure between the plug-in cylinder and the calibration block body 1. The central axis of the plug-in cylinder is parallel to the first side support plate 202 and the third side support plate 204, so that the plug-in direction of the auxiliary plug-in protrusion 103 and the plug-in direction of the protruding strip 102 are perpendicular to each other, thus fixing the calibration block body 1 and the identification block body 2 from two directions.

[0058] During the process of the auxiliary insertion protrusion 103 being inserted and fixed into the auxiliary insertion recess 210, the insertion connecting plate is fitted into the elongated recess and the insertion cylinder is fitted into the cylindrical recess. By utilizing the fact that the outer diameter of the insertion cylinder is larger than the outer diameter of the insertion connecting plate and the outer diameter of the cylindrical recess is larger than the width of the elongated recess, a size difference is formed on the auxiliary insertion protrusion 103 by the insertion connecting plate and the insertion cylinder, and a size difference is formed on the auxiliary insertion recess 210 by the cylindrical recess and the elongated recess. When the auxiliary insertion protrusion 103 and the auxiliary insertion recess 210 are inserted into each other, the size difference prevents the calibration block body 1 and the identification block body 2 from separating from each other due to external force.

[0059] like Figure 3 and Figure 4 As shown, preferably, the side of the calibration block body 1 is further provided with an internal threaded connection part 104, and the internal threaded connection part 104 and the auxiliary insertion protrusion part 103 are provided on opposite sides of the side of the calibration block body 1; the side of the identification block body 2 is further provided with a threaded connection through hole 211, and a locking bolt 212 is provided in the threaded connection through hole 211, and the threaded connection through hole 211 and the auxiliary insertion recess 210 are respectively provided on opposite sides of the side of the identification block body 2.

[0060] Based on the above technical solution, the calibration block body 1 and the identification block body 2 are connected and fixed to each other by the threaded engagement between the locking bolt 212 and the internal threaded connection part 104, which facilitates the improvement of the structural stability of the device.

[0061] In this technical solution, the mutual fixation between the calibration block body 1 and the identification block body 2 is achieved by the cooperation of three pairs of components: the protruding elongated part 102 and the insertion strip groove 209, the auxiliary insertion protrusion part 103 and the auxiliary insertion recess 210, and the internal thread connection part 104 and the locking bolt 212.

[0062] As described above, the internal threaded connection 104 and the auxiliary insertion protrusion 103 are disposed on opposite sides of the side of the calibration block body 1, and the threaded connection through hole 211 and the auxiliary insertion recess 210 are respectively disposed on opposite sides of the side of the identification block body 2. During installation, after slightly offsetting the calibration block body 1 and the identification block body 2, the protruding elongated part 102 is inserted into the insertion strip groove 209. At this time, the auxiliary insertion protrusion 103 is not inserted into the auxiliary insertion recess 210. Based on this, taking advantage of the structural relationship that the length of the protruding elongated part 102 is less than the length of the insertion strip groove 209, the two are pulled laterally so that the auxiliary insertion protrusion 103 is inserted into the auxiliary insertion recess 210. Then, the internal threaded connection 104 is locked and fixed with the locking bolt 212, thus completing the mutual fixation of the calibration block body 1 and the identification block body 2. The raised elongated part 102 and the insertion strip groove 209 ensure that the two will not shift vertically relative to each other. The auxiliary insertion protrusion 103 and the auxiliary insertion recess 210, the internal thread connection part 104 and the locking bolt 212 ensure that the two will not shift horizontally relative to each other, resulting in a better fixing effect.

[0063] like Figure 4 As shown, preferably, the lower surface of the calibration block body 1 is recessed inward to form a back groove 105. The function of the calibration block body 1 is to perform pre-navigation calibration on a maxillary sinus lift tool with a matching shape and size. The back groove 105 formed by the inward recess on the lower surface of the calibration block body 1 can reduce the weight of the calibration block body 1 while ensuring the calibration operation requirements.

[0064] like Figure 3 As shown, preferably, the top support plate 201 is provided with a first protruding strip 213, a second protruding strip 214, a third protruding strip 215 and a fourth protruding strip 216, which are sequentially connected end to end on the upper surface edge of the top support plate 201.

[0065] Based on the above structure, the first protruding strip 213, the second protruding strip 214, the third protruding strip 215 and the fourth protruding strip 216 form a protective effect on the upper surface of the top support plate 201, preventing accidental operation from causing frictional damage to the optical marking component 206.

[0066] Preferably, the optical marking component 206 includes an optical marking sheet and an optical marking pattern. The optical marking pattern is formed on the optical marking sheet, and the optical marking sheet is affixed to the upper surface of the top support plate 201. The optical marking pattern is divided into a first fan-shaped marking area, a second fan-shaped marking area, a first triangular marking area, and a second triangular marking area. The first fan-shaped marking area and the second fan-shaped marking area are arranged opposite to each other, and the first triangular marking area and the second triangular marking area are arranged opposite to each other.

[0067] Based on the above design, an optical marking pattern is formed by the first sector marking area, the second sector marking area, the first triangular marking area, and the second triangular marking area, so that the optical marking pattern forms a central marking point, which facilitates the optical navigation device to collect real-time images.

[0068] More preferably, the first sector-shaped marking area and the second sector-shaped marking area are white areas, and the first triangular marking area and the second triangular marking area are black areas. The black and white difference creates a strong contrast, making it easier for the optical navigation device to identify.

[0069] Specifically, the calibration block body 1 and the identification block body 2 are both integrally formed aluminum alloy structures. Using aluminum alloy structures for both the calibration block body 1 and the identification block body 2 enhances the strength of the device while reducing its weight.
