Description

Technical Field

[0001] This utility model relates to the field of oral medical technology, and in particular to an implant position measurement auxiliary connection component and an implant position measurement device. Background Technology

[0002] Dental implantation involves surgically inserting implants into the patient's alveolar bone. To ensure accurate alignment between the implant and the existing dentition, precise implant placement is crucial. The applicant proposes using an implant placement measurement device. This method connects an auxiliary positioning device with a signal reflection pattern to the implant in the alveolar bone, and the implant placement is determined by analyzing the acquired reflection pattern. However, if multiple implants require placement measurement, multiple auxiliary positioning devices with signal reflection patterns need to be connected to each implant. In this case, the signal reflection patterns of the different auxiliary positioning devices may obstruct each other, resulting in incomplete acquisition of the reflection pattern. Utility Model Content

[0003] In view of this, the present invention provides an auxiliary connection component and a device for implant pose measurement, which solves the technical problem that existing implant pose detection methods cannot completely obtain the reflection pattern when performing pose detection on multiple implants.

[0004] The technical solution adopted in this utility model is:

[0005] In a first aspect, this utility model provides an auxiliary connection component for measuring implant posture, comprising:

[0006] The first component includes a circumferential positioning part, a concentric positioning part, and a first connecting part. The circumferential positioning part and the first connecting part are respectively located at both ends of the first concentric positioning part in the axial direction. The concentric positioning part is provided with a first concentric positioning structure.

[0007] The second component includes a first portion and a second portion arranged along the axial direction of the second component. The diameter of the second portion is larger than the diameter of the first portion. The second component is also provided with a second concentric positioning structure and a third concentric positioning structure. The second concentric positioning structure and the third concentric positioning structure are respectively located at both ends of the axial direction of the second component. The axis of the second concentric positioning structure and the axis of the third concentric positioning structure coincide. The second concentric positioning structure cooperates with the first concentric positioning structure.

[0008] Preferably, the outer surface of the first concentric positioning structure is a frustum-shaped surface, and the diameter of the end of the first concentric positioning structure near the circumferential positioning part is larger than the diameter of the end of the first concentric positioning structure near the first connecting part.

[0009] Preferably, the circumferential positioning part includes a columnar structure with a polygonal cross-section, wherein the cross-section is perpendicular to the axial direction of the columnar structure.

[0010] Preferably, the end of the first component facing away from the first connecting portion is provided with a threaded hole.

[0011] Preferably, the first component is located within the mounting cavity of the auxiliary positioning member, and the end of the second component facing the first component abuts against the end of the auxiliary positioning member.

[0012] Preferably, the second concentric positioning structure is a mounting cavity disposed on the second component. The mounting cavity is located at the end of the second component closer to the first component. The inner wall of the mounting cavity is a frustum-shaped surface. The diameter of the end of the second concentric positioning structure closer to the first component is greater than the diameter of the end of the second concentric positioning structure farther from the first component.

[0013] Preferably, the third concentric positioning structure is a mounting cavity disposed on the second component, the mounting cavity being located at the end of the second component away from the first component, and the inner wall of the mounting cavity being a frustum-shaped cone.

[0014] Preferably, the diameter of the third concentric positioning structure at the end closer to the first component is smaller than the diameter of the second concentric positioning structure at the end farther from the first component.

[0015] Preferably, the second component is further provided with a connecting hole, which is located between the second concentric positioning structure and the third concentric positioning structure. The connecting hole connects the mounting cavity of the second concentric positioning structure and the mounting cavity of the third concentric positioning structure, and the first connecting part passes through the connecting hole into the mounting cavity of the third concentric positioning structure.

[0016] Secondly, this aspect provides an implant pose measurement device, including a connector, an auxiliary positioning component, an image acquisition device, a data processing device, and the implant pose measurement auxiliary connection assembly described in the first aspect. The auxiliary positioning component is provided with a signal reflection pattern and a second connecting portion. The second connecting portion is provided with a mounting cavity. The implant pose measurement auxiliary connection assembly is connected to the second connecting portion through the connector. At least a portion of the auxiliary connection assembly is located in the mounting cavity of the second connecting portion.

[0017] Beneficial Effects: The implant pose measurement auxiliary connection component and implant position measurement device of this utility model configure the second part of the connection component as including a first part and a second part arranged along the axial direction of the second part, with the diameter of the second part being larger than the diameter of the first part. Therefore, the first part can be inserted into the mounting cavity of the positioning aid, while the second part can abut against the end of the positioning aid outside the positioning aid. The height of the second part determines the axial distance between the positioning aid and the implant composite abutment. When the height of the second part is different, the axial distance between the positioning aid and the implant is also different. Therefore, this utility model can conveniently and flexibly adjust the axial distance between the positioning aid and the implant composite abutment by using second parts with different heights, so that the positioning aid is staggered in height after being connected to the implant composite abutment in the patient's oral cavity. This avoids mutual obstruction of the reflected patterns, allowing the image acquisition device to capture the complete reflected pattern. Attached Figure Description

[0033] Example 1:

[0034] like Figure 1 and Figure 2 As shown, this embodiment provides an implant pose measurement auxiliary connection assembly 100, which mainly includes a first component 10 and a second component 20. One end of the connection assembly near the first component 10 is connected to an auxiliary positioning member 300, and the other end away from the first component 10 is connected to an implant composite abutment 400. That is, the auxiliary positioning member 300 is connected to the implant composite abutment 400 through the connection assembly in this embodiment.

[0035] like Figure 3 As shown, the first component 10 includes a circumferential positioning part 11, a concentric positioning part 12, and a first connecting part. The circumferential positioning part 11 and the first connecting part 13 are respectively located at both ends of the first concentric positioning part 12 in the axial direction. The concentric positioning part 12 is provided with a first concentric positioning structure.

[0036] The circumferential positioning part 11 is used to limit the relative position between the connecting component and the auxiliary positioning member 300 in the circumferential direction. After the circumferential position between the connecting component and the auxiliary positioning member 300 is limited, the connecting component no longer rotates relative to the auxiliary positioning member 300.

[0037] In this embodiment, the circumferential positioning part 11 includes a polygonal columnar structure with a cross-section perpendicular to the axial direction of the columnar structure. In this embodiment, a columnar polygonal cavity complementary to the outer surface of the circumferential positioning part 11 can be provided in the mounting cavity of the auxiliary positioning member 300. After the circumferential positioning part 11 is inserted into the columnar polygonal cavity, it maintains a specific positional relationship with the auxiliary positioning member 300 in the circumferential direction under the constraint of the cavity, thereby achieving circumferential positioning between the implant pose measurement auxiliary connection assembly 100 and the auxiliary positioning member 300. This embodiment can also utilize the polygonal columnar structure of the circumferential positioning part 11 and the polygonal cavity of the auxiliary positioning member 300 to ensure the concentricity of the circumferential positioning part 11 and the auxiliary positioning member 300.

[0038] In this embodiment, the first concentric positioning part 12 structure is used to ensure that the first component 10 and the second component 20 can maintain a high degree of concentricity after being connected.

[0039] like Figure 4 and Figure 5 As shown, the second component 20 in this embodiment includes a first portion 21 and a second portion 22 arranged along the axial direction of the second component. The diameter of the second portion 22 is larger than the diameter of the first portion 21. The second component 20 is also provided with a second concentric positioning structure 23 and a third concentric positioning structure 24. The second concentric positioning structure 23 and the third concentric positioning structure 24 are respectively located at both ends of the second component 20 in the axial direction. The axis of the second concentric positioning structure 23 and the axis of the third concentric positioning structure 24 coincide. The second concentric positioning structure 23 cooperates with the first concentric positioning structure.

[0040] Because the diameter of the second portion 22 is larger than that of the first portion 21, the first portion 21 can be inserted into the mounting cavity of the positioning aid, while the second portion 22 can abut against the end of the positioning aid from the outside. With the aforementioned structure, the height of the second portion 22 determines the axial distance between the positioning aid and the implant composite abutment 400. When the height of the second portion 22 is different, the axial distance between the positioning aid and the implant composite abutment 400 is also different. Therefore, this embodiment can conveniently and flexibly adjust the axial distance between the positioning aid and the implant composite abutment 400 by using second portions 22 with different heights, thereby ensuring that the positioning aids connected to the implant composite abutment 400 in the patient's oral cavity are staggered in height. This avoids mutual obstruction of reflected patterns, allowing the image acquisition device to capture the complete pattern.

[0041] After the second concentric structure and the first concentric structure are combined, the first component 10 and the second component 20 can maintain a high degree of concentricity. Since the axis of the third concentric positioning structure 24 coincides with that of the second concentric positioning structure 23, that is, the third concentric positioning structure 24 and the second concentric positioning structure 23 maintain a concentric positional relationship, the first component 10 and the third concentric positioning structure 24 can also maintain a high degree of concentricity.

[0042] The third concentric positioning structure of the second component can be used in conjunction with the concentric positioning structure of the implant composite abutment 400 to keep the second component and the implant composite abutment 400 concentric, thereby keeping the second connecting part of the auxiliary positioning component 300 concentric with the implant composite abutment 400.

[0043] In this embodiment, the outer surface of the first concentric positioning structure is a frustum-shaped surface, and the diameter of the end of the first concentric positioning structure near the circumferential positioning part 11 is greater than the diameter of the end of the first concentric positioning structure near the first connecting part.

[0044] The second concentric positioning structure 23 is a mounting cavity disposed on the second component 20. The mounting cavity is located at the end of the second component 20 near the first component 10. The inner wall of the mounting cavity is a frustum-shaped surface. The diameter of the end of the second concentric positioning structure 23 near the first component 10 is greater than the diameter of the end of the second concentric positioning structure 23 away from the first component 10.

[0045] After the frustum surface of the first concentric positioning structure is inserted into the inner wall of the mounting cavity above the second component 20, the first component 10 and the second component 20 can remain concentric.

[0046] In this embodiment, the first component 10 has a threaded hole at one end facing away from the first connecting part. In a specific implementation, a threaded connector 200 can be used to connect the auxiliary positioning component 300 and the first component 10, wherein the threaded end of the connector 200 is connected to the threaded hole of the first component 10.

[0047] In this embodiment, the first component 10 is located within the mounting cavity of the auxiliary positioning member 300, and the end of the second component 20 facing away from the first component 10 abuts against the end of the auxiliary positioning member 300. This embodiment reduces the space occupied during pose detection by placing the assembled first component 10 within the mounting cavity of the auxiliary positioning member 300. By having the end of the second component 20 facing away from the first component 10 abut against the end of the auxiliary positioning member 300, the relative position of the connecting assembly and the auxiliary positioning member 300 in the axial direction can be accurately defined.

[0048] In this embodiment, the third concentric positioning structure 24 is a mounting cavity disposed on the second component 20. The mounting cavity is located at the end of the second component 20 away from the first component 10. The inner wall of the mounting cavity is a frustum-shaped surface. The diameter of the end of the third concentric positioning structure 24 near the first component 10 is smaller than the diameter of the end of the second concentric positioning structure 23 away from the first component 10.

[0049] The mounting cavity of the third positioning structure and the mounting cavity of the second structure are arranged opposite to each other at both ends of the second component 20, and the frustum surfaces of the two mounting cavities face opposite directions. This facilitates the connection between the second component 20 and the first component 10 while maintaining a high degree of concentricity.

[0050] Since the outer surface of the implant composite abutment 400 is a frustoconical surface, the frustoconical surface of the implant composite abutment 400 is inserted into the mounting cavity of the third positioning structure during assembly, thereby ensuring a high degree of concentricity between the third component and the second component 20 after assembly.

[0051] The second component 20 is also provided with a connecting hole 25, which is located between the second concentric positioning structure 23 and the third concentric positioning structure 24. The connecting hole 25 connects the mounting cavity of the second concentric positioning structure 23 and the mounting cavity of the third concentric positioning structure 24. The first connecting part passes through the connecting hole 25 into the third component.

[0052] The end of the first connecting part away from the first component 10 can be provided with a thread. The first connecting part is inserted into the mounting cavity of the third concentric positioning structure and then threadedly connected to the implant composite abutment 400.

[0053] Since different brands of implant composite abutments have different threaded interfaces and shapes, this embodiment can also manufacture auxiliary connection components 100 that match the threaded interfaces and shapes of implant composite abutments of different brands. The third positioning structure 24 and the first connecting structure 13 of these auxiliary connection components can match the threaded interfaces and shapes of the corresponding brand of implant composite abutment. Then, the corresponding auxiliary connection component 100 is selected according to the brand of the implant composite abutment to which the auxiliary positioning component 300 is connected. In this way, the same auxiliary positioning component 300 can be reliably connected to implant composite abutments of different brands through the auxiliary connection components 100 in this embodiment. Figure 8 and Figure 9 As can be seen from the figure, this embodiment realizes the connection between the same auxiliary positioning component 300 and composite abutments of implants from different brands through the auxiliary connection component 100.

[0054] Since the implanted composite abutment is located below the gum line, and the distance between the abutment and the gum surface varies in different situations (i.e., the perforation height varies), this embodiment can adapt to different perforation heights by selecting auxiliary connection components 100 of different heights. For example, a taller auxiliary connection component 100 can be used for cases with higher perforation heights, while a shorter auxiliary connection component 100 can be selected for cases with lower perforation heights. Figure 9 Auxiliary connection component 100 for a gingival height of 2.5mm. Figure 10 Auxiliary connection component 100 for a 4.5 mm height for penetrating the gum line. Figure 11 An auxiliary connection component 100 with a gingival height of 5.5 mm.

[0055] Example 2

[0056] like Figure 6 As shown, this embodiment provides an implant pose measurement device, which includes: a connector 200, an auxiliary positioning component 300, an image acquisition device, a data processing device, and the implant pose measurement auxiliary connection assembly 100 described in Embodiment 1. The auxiliary positioning component 300 is provided with a signal reflection pattern 310 and a second connecting portion 312. Figure 7 and Figure 8 As shown, the second connecting part 312 is provided with a mounting cavity, and the implant pose measurement auxiliary connecting component 100 is connected to the second connecting part 312 through the connector 200. At least a part of the auxiliary connecting component is located in the mounting cavity of the second connecting part 312. The image acquisition device is used to acquire the image signal reflected by the signal reflection pattern 310. The processing device is used to process the image signal to obtain the pose of the auxiliary positioning component 300.

[0057] The signal reflection pattern 310 is made of a material that can reflect signals that can be sensed by the relevant acquisition equipment. The signals reflected by the signal reflection pattern 310 can be electromagnetic signals, optical signals, sound waves, etc., without limitation. The image acquisition device is used to acquire the signals reflected by the signal reflection pattern 310 and obtain the position and orientation of the signal reflection pattern 310 in three-dimensional space based on the acquired signals. Since the position and orientation of these signal reflection patterns 310 on the auxiliary positioning component 300 are fixed after the auxiliary positioning component 300 is manufactured, knowing the position and orientation of the signal reflection pattern 310 in three-dimensional space also reveals the position and orientation of the auxiliary positioning component 300 in three-dimensional space.
