Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a pre-implantation registration device for performing a registration operation before implantation. Background Art

[0002] During the dental implant surgery, the use of an implant navigation system for guidance can improve implant accuracy and operational stability. The implant navigation system includes at least a aligner, an oral reference plate, a mobile phone reference plate, and an optical locator. The aligner can be used to align the reference plate in the coordinate system of the CT image and the coordinate system of the optical locator. Whether it is a CT scanning device or an optical locator, the real-time relative position of the patient's alveolar bone and the drill bit can be obtained, thereby performing real-time implant navigation.

[0003] During preoperative registration, a registration device is required. After the registration device is fixed and installed, it is kept relatively still with the patient's mouth. The registration operation can be performed by collecting the position information of the reflective marking points and the registration beads. In this process, it is critical that the registration device remains fixed. Before the registration is completed, if any of the reflective marking points and the registration beads shifts, it will have a great impact on the registration operation, and thus introduce hidden dangers to the subsequent dental implants.

[0004] Generally speaking, the registration device is fixedly installed on the patient's teeth. In order to ensure the stability of the registration device, the industry usually improves the bonding effect through various methods, such as filling with colloid, expanding the contact surface, etc., but these operations can only ensure that the main body and the patient remain relatively still, and cannot prevent the movement of the registration beads during the registration process. Summary of the invention

[0005] The technical problem to be solved by the utility model is that, in view of the above-mentioned defects of the prior art, a preoperative registration device for dental implant is provided, which can not only ensure the relative stillness between the main body and the patient to the greatest extent, but also further avoid the movement of the registration beads during the registration process, effectively improve the registration accuracy, and thus better ensure the treatment effect.

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

[0007] A preoperative registration device for dental implantation, comprising:

[0008] A registration assembly, the registration assembly comprising a first transverse connecting plate, a second transverse connecting plate, a first vertical clamping plate and a second vertical clamping plate, the first transverse connecting plate and the second transverse connecting plate are horizontally arranged and connected through adjacent side edges, the side edges of the first transverse connecting plate extend in a vertical direction to form the first vertical clamping plate, the side edges of the second transverse connecting plate extend in a vertical direction to form the second vertical clamping plate, and a clamping space is formed between the first vertical clamping plate and the second vertical clamping plate;

[0009] Registration beads, the first transverse connecting plate and the second transverse connecting plate are respectively provided with a plurality of registration pits, and the registration beads are nested in the registration pits;

[0012] Compared with the prior art, the beneficial effects of the present technical solution are: a clamping space is formed by the first vertical clamping plate and the second vertical clamping plate to clamp and fix the body on the patient's teeth, thereby maximizing the relative stillness between the body and the patient, and further preventing the opposite teeth from touching the alignment beads during the alignment process through the isolation component, thereby preventing the alignment beads from moving during the alignment process, effectively improving the alignment accuracy, and thus better ensuring the treatment effect.

[0013] Further, the first transverse connecting plate and the second transverse connecting plate are provided with a first arc-shaped groove and a second arc-shaped groove, and the first arc-shaped groove and the second arc-shaped groove extend along the length direction of the first transverse connecting plate and the second transverse connecting plate;

[0014] The first arc-shaped groove is formed at the connection between the first transverse connecting plate and the second transverse connecting plate and is located at the corresponding outer side of the clamping space, and the second arc-shaped groove is formed at the connection between the first transverse connecting plate and the second transverse connecting plate and is located at the corresponding inner side of the clamping space;

[0015] The first vertical clamping plate is provided with a first square sleeve on a side away from the second vertical clamping plate, and the second vertical clamping plate is provided with a second square sleeve on a side away from the first vertical clamping plate;

[0016] When the device needs to be disassembled, a tool is inserted into the first square sleeve and the second square sleeve and an external force is applied to cause the first transverse connecting plate and the second transverse connecting plate to break at the first arc-shaped groove and the second arc-shaped groove.

[0017] The beneficial effect of adopting the above scheme is: through the relatively arranged first arc-shaped groove and the second arc-shaped groove, a thinner part is formed at the connection position of the first horizontal connecting plate and the second horizontal connecting plate, and the first square sleeve and the second square sleeve are cooperated. The reverse clamp is sleeved in the first square sleeve and the second square sleeve and a reverse force is applied to the first vertical clamping plate and the second vertical clamping plate. The reverse force will cause the device to break at the first arc-shaped groove and the second arc-shaped groove, thereby facilitating the removal of the device from the patient's mouth after the alignment operation is completed.

[0018] Further, the isolation assembly includes an isolation body, a first connection portion and a second connection portion, wherein the first connection portion and the second connection portion are respectively formed on two sides of the isolation body;

[0019] The first connecting part is provided with a first square connecting column, the second connecting part is provided with a second square connecting column, the isolation component is sleeved in the first square sleeve through the first square connecting column, and the isolation component is sleeved in the second square sleeve through the second square connecting column.

[0020] The beneficial effect of adopting the above scheme is: the first square connecting column and the second square connecting column are respectively formed by the first connecting part and the second connecting part, and the first square connecting column and the second square connecting column are respectively inserted into the first square sleeve and the second square sleeve, so that the assembly of the isolation component is more stable, thereby better ensuring that the alignment beads are not affected.

[0021] Further, a plurality of elastic protrusions are respectively provided on the first square connecting column and the second square connecting column, wherein the elastic protrusions on the first square connecting column extend along the length direction of the first square connecting column, and the elastic protrusions on the second square connecting column extend along the length direction of the second square connecting column;

[0022] When the first square connecting column is sleeved in the first square sleeve, the elastic protrusion strip on the first square connecting column abuts against the inner wall of the first square sleeve; when the second square connecting column is sleeved in the second square sleeve, the elastic protrusion strip on the second square connecting column abuts against the inner wall of the second square sleeve.

[0023] The beneficial effect of adopting the above scheme is: by providing an elastic raised strip, when the first square connecting column and the second square connecting column are respectively inserted into the first square sleeve and the second square sleeve, the first square connecting column and the second square connecting column contact the inner wall of the square sleeve through the elastic raised strip, thereby effectively improving the friction force, thereby ensuring the assembly and fixing effect of the isolation component.

[0024] Furthermore, the first square connecting column gradually becomes smaller from an end close to the first connecting portion to an end away from the first connecting portion, and the second square connecting column gradually becomes smaller from an end close to the second connecting portion to an end away from the second connecting portion.

[0025] The beneficial effect of adopting the above solution is that the first square connecting column and the second square connecting column are set to a gradually larger structure, and the degree of fit between the square connecting column and the square sleeve becomes higher and higher during the sleeve connection process, thereby making the fixing effect better and better.

[0026] Further, the isolation body is provided with a recessed portion on a side surface opposite to the first transverse connecting plate and the second transverse connecting plate;

[0027] When the isolation assembly is connected to the first transverse connecting plate and the second transverse connecting plate respectively, the registration beads are located under corresponding portions of the recessed portions.

[0028] The beneficial effect of adopting the above solution is that a recessed portion is provided on the isolation body, and a gap is formed by the recessed portion to avoid direct contact between the isolation body and the alignment beads, thereby ensuring that the alignment beads do not move due to the influence of the isolation body during the alignment process.

[0029] Furthermore, a plurality of clamping protruding ribs are respectively provided on the first vertical clamping plate and the second vertical clamping plate. The clamping protruding ribs are located in the clamping space and extend in the vertical direction.

[0030] The beneficial effect of adopting the above scheme is that a plurality of clamping protrusions are respectively arranged on the first vertical clamping plate and the second vertical clamping plate. Through the clamping protrusions, the first vertical clamping plate and the second vertical clamping plate are more closely matched with the patient's teeth, and the filling effect is better, thereby making the device more stable.

[0031] Furthermore, two reinforcing ribs are arranged on the connecting rod, and the reinforcing ribs are integrally formed along the length direction and penetrate through the connecting rod.

[0032] The beneficial effect of adopting the above solution is that by providing two reinforcing ribs on the connecting rod, the strength of the connecting rod is increased, and during the alignment process, the reflective marking points on the reference plate are effectively prevented from shaking.

[0033] Furthermore, at least four circular grooves are provided on the reference plate, and reflective stickers are pasted in the circular grooves to form the reflective identification points.

[0034] The beneficial effect of adopting the above solution is that by affixing reflective stickers on the circular grooves to form reflective marking points, the structure of the device is simpler, thereby reducing the preparation cost.

[0035] Furthermore, the isolation component is a silicone structure formed by injection molding, the alignment component, the reference plate and the connecting rod are plastic structures, and the alignment beads are ceramic beads.

[0036] The beneficial effects of adopting the above scheme are: using a silicone structure as an isolation component can reduce the discomfort caused by the isolation component to the patient's oral cavity and avoid the influence of the isolation component on the alignment beads; using a plastic structure as the alignment component, reference plate and connecting rod can take into account the strength and plasticity of the device and improve the scope of application of the device.

[0048] In order to make the purpose, technical solution and advantages of the utility model clearer and more specific, the utility model is further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0049] In the description of the present invention, it should be understood that the directions or positional relationships indicated by the terms "center", "upper", "lower", "front", "back", "left", "right", etc. are based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or component referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0050] In the description of the present utility model, it should be noted that, unless otherwise clearly stipulated and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be a connection between the two components. When a component is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other component or there can also be a central component. When a component is considered to be "connected" to another element, it can be directly connected to the other element or there can be a central element at the same time. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0051] During the dental implant surgery, the use of an implant navigation system for guidance can improve implant accuracy and operational stability. The implant navigation system includes at least a aligner, an oral reference plate, a mobile phone reference plate, and an optical locator. The aligner can be used to align the reference plate in the coordinate system of the CT image and the coordinate system of the optical locator. Whether it is a CT scanning device or an optical locator, the real-time relative position of the patient's alveolar bone and the drill bit can be obtained, thereby performing real-time implant navigation.

[0052] A registration device is required for preoperative registration. After the registration device is fixed and installed, it is kept relatively still with the patient's mouth. The registration operation can be performed by collecting the position information of the reflective marking points and the registration beads. In this process, it is key to keep the registration device fixed. Before the registration is completed, once any of the reflective marking points and the registration beads shift, it will have a great impact on the registration operation. If there is a problem with the registration operation, the guidance provided by the implant navigation system will be deviated during the implementation of the dental implant, which will introduce hidden dangers to the subsequent dental implants.

[0053] Generally speaking, the registration device is fixedly installed on the patient's teeth. In order to ensure the stability of the registration device, the industry usually improves the bonding effect through various methods, such as filling with colloid, expanding the contact surface, etc., but these operations can only ensure that the main body and the patient remain relatively still, and cannot prevent the movement of the registration beads during the registration process.

[0054] like Figure 1 and Figure 2 As shown, in order to solve the above problems, the utility model provides a preoperative registration device for dental implant, including a registration component 1, a registration bead 2, an isolation component 3 and a reference plate 4. The registration bead 2, the isolation component 3 and the reference plate 4 are arranged on the registration component 1, and the registration bead 2 is used to cooperate with the CT scanning instrument to realize data acquisition. In particular, the biggest difference between the present technical solution and the prior art is that the isolation component 3 is provided. The reference plate 4 is used to cooperate with the optical locator to realize data acquisition. The CT scanning instrument and the optical locator used in the registration process, their operation mode, data acquisition and processing process and registration steps are all prior art, and the present technical solution does not make any improvement on this.

[0055] The alignment component 1 includes a first transverse connecting plate 101, a second transverse connecting plate 102, a first vertical clamping plate 103 and a second vertical clamping plate 104. The first transverse connecting plate 101 and the second transverse connecting plate 102 are horizontally arranged and connected through adjacent side edges. The side edges of the first transverse connecting plate 101 extend in the vertical direction to form the first vertical clamping plate 103, and the side edges of the second transverse connecting plate 102 extend in the vertical direction to form the second vertical clamping plate 104. A clamping space is formed between the first vertical clamping plate 103 and the second vertical clamping plate 104. The specific structure of the alignment component 1 can be understood as follows: the first horizontal connecting plate 101 and the second horizontal connecting plate 102 are connected to form an integral structure, and the first vertical clamping plate 103 and the second vertical clamping plate 104 are respectively arranged on both sides to form a clamping space, and the device can be installed and fixed on the patient's teeth by using this clamping space: the clamping space is inserted into the teeth, and the first vertical clamping plate 103 and the second vertical clamping plate 104 will respectively abut against the tongue side and the labial side of the teeth, and then the first vertical clamping plate 103 and the second vertical clamping plate 104 are filled with adhesive between the teeth to fix them, so that the device can be fixed on the teeth. The reference plate 4 is fixedly arranged on the first vertical clamping plate 103 by a connecting rod 5, and at least 4 reflective marking points are arranged on the reference plate 4.

[0056] In addition to being used to connect and fix the first vertical clamping plate 103 and the second vertical clamping plate 104, the first horizontal connecting plate 101 and the second horizontal connecting plate 102 are respectively provided with a plurality of registration pits, and the registration beads 2 are nested in the registration pits. It can be understood that the first horizontal connecting plate 101 and the second horizontal connecting plate 102 are integrally formed with a plurality of registration pits, and the hard registration beads 2 are subsequently pressed into the registration pits by external force.

[0057] In particular, the isolation component 3 is a block structure, one side of the isolation component 3 is detachably connected to the first transverse connecting plate 101, the other side of the isolation component 3 is detachably connected to the second transverse connecting plate 102, and the isolation component 3 is located above the corresponding plurality of alignment beads 2.

[0058] The technical problem to be solved by the present technical solution is to prevent the registration beads 2 from moving during the registration process. In clinical practice, the main factor causing the registration beads 2 to move is the patient's accidental touch. When the device is fixed on one side of the teeth, the patient's other teeth may bite due to fatigue, and at this time they will touch the registration beads 2. In order to solve this problem, the present technical solution is provided with a block-shaped isolation component 3, which is detachably arranged on the first transverse connecting plate 101 and the second transverse connecting plate 102. The isolation component 3 is used to isolate the two rows of teeth, so that even if the patient bites, the registration beads 2 will not be affected.

[0059] Based on the above technical solution, a clamping space is formed by the first vertical clamping plate 103 and the second vertical clamping plate 104 to clamp and fix on the patient's teeth, thereby ensuring that the main body and the patient remain relatively still to the greatest extent possible. Further, the isolation component 3 is used to prevent the opposite teeth from touching the alignment beads 2 during the alignment process, thereby preventing the alignment beads 2 from moving during the alignment process, thereby effectively improving the alignment accuracy and better ensuring the treatment effect.

[0060] like Figure 1 and Figure 2 As shown, the first transverse connecting plate 101 and the second transverse connecting plate 102 are provided with a first arc groove 105 and a second arc groove 106, and the first arc groove 105 and the second arc groove 106 extend along the length direction of the first transverse connecting plate 101 and the second transverse connecting plate 102. Specifically, the first arc groove 105 is formed at the connection of the first transverse connecting plate 101 and the second transverse connecting plate 102 and is located at the corresponding outer side of the clamping space, and the second arc groove 106 is formed at the connection of the first transverse connecting plate 101 and the second transverse connecting plate 102 and is located at the corresponding inner side of the clamping space. On the integral plate-like structure formed by the first transverse connecting plate 101 and the second transverse connecting plate 102, the first arc groove 105 and the second arc groove 106 are used to form a thinner part on the first transverse connecting plate 101 and the second transverse connecting plate 102, so as to facilitate the destructive disassembly of the first transverse connecting plate 101 and the second transverse connecting plate 102 after the registration is completed.

[0061] Correspondingly, a first square sleeve 107 is provided on a side of the first vertical clamping plate 103 away from the second vertical clamping plate 104 , and a second square sleeve is provided on a side of the second vertical clamping plate 104 away from the first vertical clamping plate 103 .

[0062] When the device needs to be disassembled, a tool is inserted into the first square sleeve 107 and the second square sleeve 108 and an external force is applied. Since the first square sleeve 107 and the second square sleeve 108 are respectively arranged on the side of the first vertical clamping plate 103 away from the second vertical clamping plate 104, the external force will drive the first vertical clamping plate 103 to drive the first transverse connecting plate 101 to form a movement trend in one direction, and at the same time drive the second vertical clamping plate 104 to drive the second transverse connecting plate 102 to form a movement trend in another direction, until the external force is large enough, the first transverse connecting plate 101 and the second transverse connecting plate 102 will be broken at the first arc groove 105 and the second arc groove 106.

[0063] Based on the above technical solution, a thinner portion is formed at the connection position of the first horizontal connecting plate 101 and the second horizontal connecting plate 102 by relatively setting the first arc-shaped groove 105 and the second arc-shaped groove 106, and cooperates with the first square sleeve 107 and the second square sleeve 108. A reverse clamp is used to be sleeved in the first square sleeve 107 and the second square sleeve 108 and apply a reverse force to the first vertical clamping plate 103 and the second vertical clamping plate 104. The reverse force will cause the device to break at the first arc-shaped groove 105 and the second arc-shaped groove 106, thereby facilitating the removal of the device from the patient's mouth after the alignment operation is completed.

[0064] like Figure 3 and Figure 4 As shown, the isolation component 3 includes an isolation body 301, a first connecting part 302 and a second connecting part 303, and the first connecting part 302 and the second connecting part 303 are respectively formed on both sides of the isolation body 301; a first square connecting column 304 is arranged on the first connecting part 302, and a second square connecting column 305 is arranged on the second connecting part 303, and the isolation component 3 is sleeved in the first square sleeve 107 through the first square connecting column 304, and the isolation component 3 is sleeved in the second square sleeve 108 through the second square connecting column 305.

[0065] Based on the above structure, the first square connecting column 304 and the second square connecting column 305 are respectively formed by the first connecting part 302 and the second connecting part 303. When the isolation component 3 needs to be installed, the first square connecting column 304 and the second square connecting column 305 are respectively inserted into the first square sleeve 107 and the second square sleeve 108, so that the assembly of the isolation component 3 can be made more stable, thereby better ensuring that the alignment bead 2 is not affected.

[0066] Combination Figure 3 and Figure 4It can be seen that a plurality of elastic raised strips 306 are respectively provided on the first square connecting column 304 and the second square connecting column 305. The elastic raised strips 306 on the first square connecting column 304 extend along the length direction of the first square connecting column 304, and the elastic raised strips 306 on the second square connecting column 305 extend along the length direction of the second square connecting column 305.

[0067] When the first square connecting column 304 is sleeved in the first square sleeve 107, the elastic raised strip 306 on the first square connecting column 304 abuts against the inner wall of the first square sleeve 107; when the second square connecting column 305 is sleeved in the second square sleeve 108, the elastic raised strip 306 on the second square connecting column 305 abuts against the inner wall of the second square sleeve 108.

[0068] By providing an elastic raised strip 306, when the first square connecting column 304 and the second square connecting column 305 are respectively inserted into the first square sleeve 107 and the second square sleeve 108, the first square connecting column 304 and the second square connecting column 305 contact the inner wall of the square sleeve through the elastic raised strip 306, effectively improving the friction force, thereby ensuring the assembly and fixing effect of the isolation component 3.

[0069] Preferably, the first square connecting column 304 gradually becomes smaller from one end close to the first connecting portion 302 to one end away from the first connecting portion 302 , and the second square connecting column 305 gradually becomes smaller from one end close to the second connecting portion 303 to one end away from the second connecting portion 303 .

[0070] The first square connecting column 304 and the second square connecting column 305 are arranged to have a gradually enlarged structure. During the socketing process, the degree of fit between the square connecting column and the square sleeve becomes increasingly higher, that is, when the square connecting column is inserted into the square sleeve, the deeper the insertion, the more secure the connection, thereby making the fixing effect increasingly better.

[0071] like Figure 4 As shown, the isolation body 301 is provided with a recessed portion 307 on one side surface opposite to the first transverse connecting plate 101 and the second transverse connecting plate 102; when the isolation assembly 3 is connected to the first transverse connecting plate 101 and the second transverse connecting plate 102, respectively, the registration beads 2 are located under the corresponding recessed portions 307. The recessed portion 307 is provided on the isolation body 301, and a gap is formed by the recessed portion 307 to avoid direct contact between the isolation body 301 and the registration beads 2, thereby ensuring that the registration beads 2 do not move due to the influence of the isolation body 301 during the registration process.

[0072] like Figure 5As shown, preferably, a plurality of clamping protruding ribs 109 are respectively provided on the first vertical clamping plate 103 and the second vertical clamping plate 104 , and the clamping protruding ribs 109 are located in the clamping space, and the clamping protruding ribs 109 extend in the vertical direction.

[0073] A plurality of clamping protruding ribs 109 are respectively provided on the first vertical clamping plate 103 and the second vertical clamping plate 104. The clamping protruding ribs 109 have two functions: first, when the alignment component 1 is put on the teeth, the clamping protruding ribs 109 make the contact between the alignment component 1 and the teeth more complete, thereby increasing the friction between the two; second, a sawtooth-like spatial structure is formed. When the glue is applied and fixed, the glue will fill the space between the alignment component 1 and the teeth, and the sawtooth-like spatial structure formed by the clamping protruding ribs 109 can make the occlusion between the glue and the alignment component 1 and the teeth tighter. Therefore, the clamping protruding ribs 109 make the first vertical clamping plate 103 and the second vertical clamping plate 104 fit more closely with the patient's teeth, and the glue filling effect is better, thereby making the stability of the device higher.

[0074] like Figure 6 As shown, preferably, two reinforcing ribs 501 are provided on the connecting rod 5, and the reinforcing ribs 501 are integrally formed along the length direction and are arranged on the connecting rod 5. By providing two reinforcing ribs 501 on the connecting rod 5, the strength of the connecting rod 5 is increased, and during the registration process, the reflective marking points on the reference plate 4 are effectively prevented from shaking.

[0075] Preferably, at least four circular grooves are provided on the reference plate 4, and reflective stickers are pasted in the circular grooves to form the reflective identification points. By pasting reflective stickers on the circular grooves to form reflective identification points, the structure of the device is simpler, thereby reducing the manufacturing cost.

[0076] Specifically, the isolation component 3 is a silicone structure formed by injection molding, the registration component 1, the reference plate 4 and the connecting rod 5 are plastic structures, and the registration beads 2 are ceramic beads. Using a silicone structure as the isolation component 3 can reduce the discomfort caused by the isolation component 3 to the patient's oral cavity and avoid the isolation component 3 from affecting the registration beads 2; using a plastic structure as the registration component 1, the reference plate 4 and the connecting rod 5 can take into account the strength and plasticity of the device and improve the scope of application of the device.

[0077] It should be understood that the application of the present invention is not limited to the above examples. For ordinary technicians in this field, improvements or changes can be made according to the above description. All these improvements and changes should fall within the scope of protection of the claims attached to the present invention.
