Description

Technical Field

[0001] This utility model relates to the field of medical equipment technology, and specifically to a registration device, which is an auxiliary device for navigation registration before performing oral treatment surgery. Background Technology

[0002] Dental implant surgery is currently the most effective way to treat tooth loss. It involves drilling a hole in the alveolar bone corresponding to the missing tooth, inserting an implant into the hole, and then fixing an abutment and crown to the implant to form a complete tooth structure, which replaces the missing tooth and serves functions such as chewing and aesthetics.

[0003] Drilling an implant hole in the alveolar bone is one of the preliminary procedures for dental implant surgery. The operator needs to drill an implant hole at a specific location and in a specific direction to a specific depth according to the patient's oral condition. This has a decisive impact on the fixation and installation of the implant. It can be said that drilling an ideal implant hole is the foundation for achieving the ideal implant surgery treatment effect.

[0004] The drilling process involves equipment such as binocular navigation systems and CT scanners. It requires establishing connections between the navigation system's 3D coordinate system, the CT scanner's 3D coordinate system, and the patient's 3D coordinate system to determine the coordinate transformation relationship between any two of these three systems. This process of establishing connections is known in the industry as registration.

[0005] Existing registration devices suffer from structural design flaws that cause prolonged pressure on the patient's lips. During registration, whether acquiring CT data or image data, the connecting rod continuously stretches the patient's lips, causing significant discomfort. The industry urgently needs to address these issues. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide an oral treatment navigation and registration device that addresses the above-mentioned deficiencies of the prior art. The device adopts a split structure design and does not require the connection of a connecting rod and an oral reference plate during the acquisition of CT data, thus greatly reducing the discomfort caused to the patient.

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

[0008] A dental treatment navigation and registration device, comprising:

[0009] A connecting base plate is provided, which is a square plate structure and is arranged in a horizontal direction. The connecting base plate is provided with multiple registration beads and multiple registration pits.

[0010] A first clamping plate and a second clamping plate are arranged vertically. The first clamping plate and the second clamping plate are respectively fixed to a set of opposite sides of the connecting base plate through their respective sides. A clamping space is formed between the first clamping plate and the second clamping plate.

[0011] A plug-in block is disposed on the outer side wall of the first clamping plate or the second clamping plate, and a plug-in hole is provided on the plug-in block;

[0012] A mouth reference plate is provided with multiple circular identification patterns. A connecting rod is also provided on the mouth reference plate. One end of the connecting rod is fixedly disposed on the mouth reference plate, and the other end of the connecting rod is inserted and fixed in the insertion hole.

[0013] Compared with existing technologies, the advantages of this technical solution are: adopting a split structure design, the device is divided into two parts, the main body and the reference plate, and connected by a connecting rod. After the main body is installed and fixed on the patient's mouth, the oral reference plate does not need to be installed when CT data needs to be acquired. The oral reference plate is installed only when image data needs to be acquired, which can greatly reduce the discomfort caused to the patient.

[0014] Furthermore, the first clamping plate and the second clamping plate are provided with at least one glue-filling through hole, the glue-filling through hole is a strip-shaped through hole, and the glue-filling through hole is arranged in the vertical direction.

[0015] The beneficial effects of the above solution are: at least one injection hole is provided on the first clamping plate and the second clamping plate, and the fixation adhesive can be injected into the clamping space from different directions through the injection hole, so that the fixation adhesive can effectively fill the clamping space and the patient's teeth, thereby improving the fixation effect of the device.

[0016] Furthermore, when the plug-in block is disposed on the first clamping plate, the first clamping plate is provided with one potting through hole, and the second clamping plate is provided with two potting through holes;

[0017] When the plug block is disposed on the second clamping plate, the second clamping plate is provided with one glue-filling through hole, and the first clamping plate is provided with two glue-filling through holes.

[0018] The beneficial effects of adopting the above scheme are: making full use of the structure of the first clamping plate and the second clamping plate, and reasonably setting the glue-filling through holes and plug-in blocks, making the structure of this device more scientific.

[0019] Furthermore, the inner sidewalls of the first clamping plate and the second clamping plate are provided with a plurality of clamping protrusions, which are arranged in a vertical direction, and a colloid-filled space is formed between two adjacent clamping protrusions.

[0020] The beneficial effects of the above scheme are: multiple clamping protrusions are respectively provided on the inner sidewalls of the first clamping plate and the second clamping plate in the vertical direction. By using two adjacent clamping protrusions, multiple relatively independent colloid filling spaces are separated between the clamping space and the patient's teeth, which further improves the bonding and fixing effect.

[0021] Furthermore, one end of the connecting rod extends outward along its length to form a first snap-fit ​​strip and a second snap-fit ​​strip. The first snap-fit ​​strip and the second snap-fit ​​strip are spaced apart. The fixed ends of the first snap-fit ​​strip and the second snap-fit ​​strip are located at the end of the connecting rod. The first snap-fit ​​strip and the second snap-fit ​​strip extend outward along the length of the connecting rod to form a movable end. A first snap-fit ​​protrusion is formed at the end of the first snap-fit ​​strip, and a second snap-fit ​​protrusion is formed at the end of the second snap-fit ​​strip.

[0022] The insertion hole has a first locking part formed by an inward recess at the bottom, and the insertion hole has a second locking part formed by a locking through hole on the upper surface of the connecting base plate; when the connecting rod is inserted and fixed in the insertion hole, the first locking protrusion is locked and fixed on the first locking part, and the second locking protrusion is locked and fixed on the second locking part.

[0023] The beneficial effect of adopting the above scheme is that after the connecting rod is inserted and fixed in the insertion hole, the elasticity of the first and second locking strips is used to lock the first and second locking strips onto the first and second locking parts respectively, thereby improving the overall structural integrity of the device.

[0024] Furthermore, the circular recognition patch is composed of a first sector-shaped white block, a second sector-shaped white block, a first sector-shaped black block, and a second sector-shaped black block. The first sector-shaped white block and the second sector-shaped white block are arranged opposite each other, and the first sector-shaped black block and the second sector-shaped black block are arranged opposite each other. The first sector-shaped white block, the second sector-shaped white block, the first sector-shaped black block, and the second sector-shaped black block form the circular recognition patch.

[0025] The beneficial effect of adopting the above scheme is that the circular recognition pattern is formed by the first sector white block, the second sector white block, the first sector black block and the second sector black block, which effectively improves the recognition accuracy of the circular recognition pattern.

[0026] Furthermore, the connecting rod is a straight rod structure or a bent rod structure.

[0027] The beneficial effects of adopting the above scheme are: depending on the actual situation of the patient's oral cavity, using a straight rod structure or a curved rod structure as the connecting rod can appropriately adjust the angle between the oral reference plate and the binocular navigator, so that the binocular navigator can better capture the real-time image of the oral reference plate.

[0028] Furthermore, five registration beads are provided, and the registration beads are ceramic beads.

[0029] The beneficial effect of adopting the above scheme is that using ceramic beads as registration beads makes it easier for CT scanners to identify them.

[0030] Furthermore, the connecting base plate is provided with a registration bead fixing boss and a registration bead fixing recess. The connecting base plate forms the registration bead fixing boss by protruding outward, and the connecting base plate forms the registration bead fixing recess by recessing inward.

[0031] One registration bead is fixedly disposed on the registration bead fixing boss, one registration bead is fixedly disposed on the registration bead fixing recess, and three registration beads are fixedly disposed on the upper surface of the connecting base plate.

[0032] The beneficial effects of adopting the above scheme are: five registration beads are fixedly set on the upper surface of the registration bead fixing boss, the registration bead fixing recess and the connecting base plate, and the height difference between the registration bead fixing boss, the registration bead fixing recess and the connecting base plate is used to make the five registration beads be in at least three horizontal planes, which meets the spatial positioning requirements of the CT scanner.

[0033] Furthermore, five registration pits are provided;

[0034] The connecting base plate has a first registration protrusion and a second registration protrusion formed by protruding outwards. The heights of the first registration protrusion and the second registration protrusion are different. The connecting base plate has a first registration recess and a second registration recess formed by inwards. The depths of the first registration recess and the second registration recess are different.

[0035] The first registration protrusion, the second registration protrusion, the first registration recess, the second registration recess, and the upper surface of the connecting base plate are each provided with a registration recess.

[0036] The beneficial effects of the above scheme are as follows: five registration recesses are fixedly set on the upper surfaces of the first registration protrusion, the second registration protrusion, the first registration recess, the second registration recess, and the connecting base plate, respectively. By utilizing the height difference between the first registration protrusion, the second registration protrusion, the first registration recess, the second registration recess, and the connecting base plate, the five registration recesses are located at different horizontal planes. By using the registration recesses at different horizontal planes for registration operations, registration errors can be effectively avoided and registration accuracy can be improved.

[0052] Dental implant surgery is currently the most effective way to treat tooth loss. It involves drilling a hole in the alveolar bone corresponding to the missing tooth, inserting an implant into the hole, and then fixing an abutment and crown to the implant to form a complete tooth structure, which replaces the missing tooth and serves functions such as chewing and aesthetics.

[0053] Drilling an implant hole in the alveolar bone is one of the preliminary procedures for dental implant surgery. The operator needs to drill an implant hole at a specific location and in a specific direction to a specific depth according to the patient's oral condition. This has a decisive impact on the fixation and installation of the implant. It can be said that drilling an ideal implant hole is the foundation for achieving the ideal implant surgery treatment effect.

[0054] The drilling process involves equipment such as binocular navigation systems and CT scanners. It requires establishing connections between the navigation system's 3D coordinate system, the CT scanner's 3D coordinate system, and the patient's 3D coordinate system to determine the coordinate transformation relationship between any two of these three systems. This process of establishing connections is known in the industry as registration.

[0055] Existing registration devices suffer from structural design flaws that cause prolonged pressure on the patient's lips. Specifically, the registration device consists of a main body and a reference plate, connected by a connecting rod to form a single unit. The main body, reference plate, and connecting rod are inseparable. During registration, whether acquiring CT data or image data, the connecting rod continuously stretches the patient's lips, causing significant discomfort. The industry urgently needs to address this issue.

[0056] like Figure 1 and Figure 2 As shown, to solve the above problems, this utility model provides an oral treatment navigation registration device, including a connecting base plate 1, a first clamping plate 2, a second clamping plate 3, a plug block 4, and an oral reference plate 5. The connecting base plate 1, the first clamping plate 2, and the second clamping plate 3 form the body of the registration device. The plug block 4 is formed on the body structure. The oral reference plate 5 is connected to the plug block 4 through a connecting rod 6. The oral reference plate 5 is provided with a plurality of circular identification patches 501.

[0057] Specifically, the connecting base plate 1 is a square plate structure, and it is provided with a plurality of registration beads 101 and a plurality of registration recesses 102. The first clamping plate 2 and the second clamping plate 3 are arranged at intervals relative to each other, and are respectively fixed to a set of opposite sides of the connecting base plate 1 through their respective sides, forming a clamping space between them. Based on this, the mouth reference plate 5 is then fixed to the connecting base plate 1, the first clamping plate 2, or the second clamping plate 3, thus forming a registration device with a basic structure.

[0058] The registration process based on this fundamental structure is as follows: After fixing the registration device onto the patient's jaw, CT data is acquired, and the relative position between the missing tooth and the registration bead 101 of the registration device is determined using a CT scanner. Simultaneously, image data is acquired, and the relative position between the registration bead 101 and the registration pit 102 of the registration device is determined using a binocular navigation system. After acquiring the above data, a transformation relationship can be established between the navigation system's three-dimensional coordinate system, the CT three-dimensional coordinate system, and the patient's three-dimensional coordinate system, using the registration bead 101 as an intermediary. Furthermore, after completing the CT scan, the registration device, along with the oral reference plate 5 on the registration device, can be used as the oral reference plate 5.

[0059] To address the problem of uneven weight distribution caused by structural design defects in existing registration devices, in this technical solution, the insertion block 4 is disposed on the outer side wall of the first clamping plate 2 or the second clamping plate 3, and the insertion block 4 is provided with an insertion hole 401; one end of the connecting rod 6 is fixedly disposed on the mouth reference plate 5, and the other end of the connecting rod 6 is inserted and fixed in the insertion hole 401.

[0060] The registration device in this technical solution is no different from existing registration devices in terms of registration operation. The main innovation of this technical solution lies in its split structure design, which divides the device into two parts: the main body and the reference plate, connected by a connecting rod 6. The main body structure includes a connecting base plate 1, a first clamping plate 2, and a second clamping plate 3. After the main body is installed and fixed on the patient's oral cavity, the oral reference plate does not need to be installed when CT data needs to be acquired. The oral reference plate is installed only when image data needs to be acquired, which can greatly reduce the discomfort caused to the patient.

[0061] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, at least one glue-filling through hole 7 is provided on the first clamping plate 2 and the second clamping plate 3. The glue-filling through hole 7 is a strip-shaped through hole and is arranged in the vertical direction.

[0062] The process of fixing this registration device to the patient's teeth is as follows: inject the fixation colloid into the clamping space, and then put the main body on the patient's teeth. At this time, the fixation colloid will fill the space between the clamping space and the patient's teeth. After the fixation colloid cures, the main body of this registration device can be fixed to the patient's teeth. Then, insert the interface reference plate 5 on this basis to complete the installation and fixation of this registration device.

[0063] When the amount of fixative colloid is insufficient, the clamping space and the patient's teeth cannot be completely filled, which will affect the fixation effect. To solve this problem, at least one injection hole 7 is provided on the first clamping plate 2 and the second clamping plate 3. The fixative colloid can be injected into the clamping space from different directions through the injection hole 7, so that the fixative colloid can effectively fill the clamping space and the patient's teeth, thereby improving the fixation effect of the device.

[0064] Preferably, when the plug-in block 4 is disposed on the first clamping plate 2, the first clamping plate 2 is provided with one glue-filling through hole 7, and the second clamping plate 3 is provided with two glue-filling through holes 7; when the plug-in block 4 is disposed on the second clamping plate 3, the second clamping plate 3 is provided with one glue-filling through hole 7, and the first clamping plate 2 is provided with two glue-filling through holes 7.

[0065] Through the above structural design, the structure of the first clamping plate 2 and the second clamping plate 3 can be fully utilized, and the glue-filling through hole 7 and the plug-in block 4 can be reasonably set, making the structure of this device more scientific.

[0066] like Figure 4 As shown, the inner walls of the first clamping plate 2 and the second clamping plate 3 are provided with multiple clamping protrusions 8. The clamping protrusions 8 are arranged vertically, and a colloid-filled space is formed between two adjacent clamping protrusions 8. Based on the above structure, multiple clamping protrusions 8 are respectively arranged vertically on the inner walls of the first clamping plate 2 and the second clamping plate 3. By using two adjacent clamping protrusions 8, multiple relatively independent colloid-filled spaces are separated between the clamping space and the patient's teeth, further improving the bonding and fixation effect.

[0067] like Figure 5 As shown, one end of the connecting rod 6 extends outward along its length to form a first locking strip 601 and a second locking strip 602. The first locking strip 601 and the second locking strip 602 are spaced apart. The fixed ends of the first locking strip 601 and the second locking strip 602 are located at the end of the connecting rod 6. The first locking strip 601 and the second locking strip 602 extend outward along the length of the connecting rod 6 to form a movable end. A first locking protrusion 603 is formed at the end of the first locking strip 601, and a second locking protrusion 604 is formed at the end of the second locking strip 602.

[0068] like Figure 6 As shown, the insertion hole 401 has a first snap-fit ​​portion 402 formed by the bottom being recessed inward, and the insertion hole 401 has a second snap-fit ​​portion 403 formed by the snap-fit ​​through hole provided on the upper surface of the connecting base plate 1.

[0069] The first locking strip 601 and the second locking strip 602 are fixed at one end and free at the other, possessing elasticity. During the process of inserting and fixing the connecting rod 6 into the insertion hole 401, the insertion hole 401 initially forces the first locking strip 601 and the second locking strip 602 closer together until both the first locking protrusion 603 and the second locking protrusion 604 can be accommodated within the insertion hole 401. Subsequently, with continued application of thrust, the first locking strip 601 and the second locking strip 602 advance within the insertion hole 401 until they reach the end of the insertion hole 401. At this point, the first locking protrusion 603 is locked and fixed to the first locking part 402, and the second locking protrusion 604 is locked and fixed to the second locking part 403.

[0070] Based on the above structure, after the connecting rod 6 is inserted and fixed in the insertion hole 401, the elasticity of the first locking strip 601 and the second locking strip 602 is used to lock the first locking strip 601 and the second locking strip 602 onto the first locking part 402 and the second locking part 403 respectively, thereby improving the overall structural integrity of the device.

[0071] Preferably, the circular identification patch 501 is composed of a first sector-shaped white block, a second sector-shaped white block, a first sector-shaped black block, and a second sector-shaped black block. The first sector-shaped white block and the second sector-shaped white block are arranged opposite to each other, and the first sector-shaped black block and the second sector-shaped black block are arranged opposite to each other. The first sector-shaped white block, the second sector-shaped white block, the first sector-shaped black block, and the second sector-shaped black block form the circular identification patch 501.

[0072] Based on the above design, a circular recognition patch 501 is formed by the first sector-shaped white block, the second sector-shaped white block, the first sector-shaped black block, and the second sector-shaped black block, which effectively improves the recognition accuracy of the circular recognition patch 501.

[0073] The circular identification patch 501 on the oral imaging plate serves to provide image data for the binocular navigation system to determine the patient's real-time pose. Therefore, for this registration device to function properly, the circular identification patch 501 on the oral imaging plate must be at a suitable angle so that the binocular navigation system can acquire image data. In clinical practice, different patients and different missing tooth positions can affect the orientation of the oral imaging plate. To ensure that the oral imaging plate and the binocular navigation system are at a recognizable angle, in this technical solution, the connecting rod 6 is a straight rod structure or a bent rod structure.

[0074] Based on the above structure, a straight rod or a curved rod can be used as the connecting rod 6 according to the actual situation of the patient's oral cavity. This allows for appropriate adjustment of the angle between the oral reference plate 5 and the binocular navigator, enabling the binocular navigator to better capture the real-time image of the oral reference plate 5.

[0075] Preferably, the registration bead 101 is a ceramic bead. Using a ceramic bead as the registration bead 101 facilitates recognition by the CT scanner.

[0076] Preferably, five registration beads 101 are provided, and registration bead fixing bosses 103 and registration bead fixing recesses 104 are provided on the connecting base plate 1. The connecting base plate 1 forms the registration bead fixing bosses 103 by protruding outward, and the connecting base plate 1 forms the registration bead fixing recesses 104 by inward.

[0077] Of the five registration beads 101, one registration bead 101 is fixedly disposed on the registration bead fixing boss 103, one registration bead 101 is fixedly disposed on the registration bead fixing recess 104, and three registration beads 101 are fixedly disposed on the upper surface of the connecting base plate 1.

[0078] Based on the above structure, five registration beads 101 are fixedly mounted on the upper surfaces of the registration bead fixing boss 103, the registration bead fixing recess 104, and the connecting base plate 1. The height difference between the registration bead fixing boss 103, the registration bead fixing recess 104, and the connecting base plate 1 ensures that the five registration beads 101 are in at least three horizontal planes, thus meeting the spatial positioning requirements of the CT scanner.

[0079] Preferably, five registration recesses 102 are provided. On the connecting base plate 1, the connecting base plate 1 has a first registration protrusion 105 and a second registration protrusion 106 formed by outward protrusion, the heights of the first registration protrusion 105 and the second registration protrusion 106 are different, and the connecting base plate 1 has a first registration recess 107 and a second registration recess 108 formed by inward concavity, the depths of the first registration recess 107 and the second registration recess 108 are different; one registration recess 102 is provided on each of the first registration protrusion 105, the second registration protrusion 106, the first registration recess 107, and the second registration recess 108 and the upper surface of the connecting base plate 1.

[0080] Based on the above structure, five registration recesses 102 are respectively fixedly disposed on the upper surface of the first registration protrusion 105, the second registration protrusion 106, the first registration recess 107, the second registration recess 108, and the connecting base plate 1. By utilizing the height difference between the first registration protrusion 105, the second registration protrusion 106, the first registration recess 107, the second registration recess 108, and the connecting base plate 1, the five registration recesses 102 are located on different horizontal planes. By using the registration recesses 102 on different horizontal planes for registration operations, registration errors can be effectively avoided and registration accuracy can be improved.

[0081] 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.
