Description

Technical Field

[0001] The utility model relates to the technical field of oral medical instruments, in particular to an anchoring nail device with multiple registration points and an oral implant navigation registration component. Background Art

[0002] Oral implant surgery requires a series of precise procedures performed within the oral cavity under local anesthesia. Due to the oral cavity's lack of direct vision and confined space, oral implant surgery is associated with a high incidence of complications. In recent years, research and development related to oral implant navigation has been extensively conducted both domestically and internationally. With the advancement of computer technology, surgical navigation, with its precision, flexibility, and minimally invasive nature, has revolutionized surgical procedures, leading modern medicine from "intuitive medicine" to "precision medicine."

[0003] The existing navigation implantation scheme is to use implantation guides for navigation implantation. During the navigation implantation operation, the guide is used to fix the visual marker connector and provide an intraoral registration point for easy position determination. The specific operation process of the implantation guide operation is: first, obtain the patient's preoperative CBCT data and oral scan data, then design the implant and guide plan and confirm the plan, and finally generate the implantation guide data for 3D printing. The doctor will try on and modify the patient according to the 3D printed implantation guide. This step takes a long time because there may be failures in the trial fitting process of the patient, which will lead to the re-3D printing of the implantation guide. Therefore, this process is a process of repeated trials, and the implantation operation can only be performed after the trial fitting is successful.

[0004] Moreover, there are defects in guide plate implantation during implant surgery. For example, for edentulous patients with a large number of missing teeth or even a missing edentulous arch, wearing traditional oral implant guides can easily lead to displacement due to the lack of fixed positions, making it difficult to achieve high implant accuracy and making it impossible to perform implant surgery.

Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art can combine and combine different embodiments or examples described in this specification and the features of different embodiments or examples without contradiction.

[0035] The following combination Figures 1 to 11 The specific structure and working process of the anchorage nail device with multiple registration points and the oral implant navigation registration component of the present invention are described.

[0036] An embodiment of the present invention provides an anchor nail device with multiple registration points, combined with Figure 1 and Figure 2 As shown, it includes an anchor pin 1 and a base 2, wherein the anchor pin 1 is suitable for being fixed to the patient's oral jaw; the base 2 is detachably connected to the anchor pin 1, and the base 2 includes a top end face 21, a bottom end face 22 and multiple side faces, one of which is formed as an oblique surface 23, and registration points 24 are respectively provided on the top end face 21 and the oblique surface 23.

[0037] It can be understood that the support nail device with multiple registration points in this embodiment is a new type of support nail implant surgery structure, which can be applied to replace the traditional guide plate implantation by using a support nail device with multiple registration points + connecting bracket. This method is more convenient and quick, and does not require printing a 3D guide plate, which greatly shortens the preoperative preparation time. In addition, the support nail device is directly connected to the patient's jaw, reducing the assembly error introduced by the intermediate transition, and providing a basis for subsequent precise navigation surgery. The base 2 in this embodiment is provided with an oblique surface 23. The so-called oblique surface means that the angle formed by it and the top end face 21 or the bottom end face 22 is not a right angle. Generally speaking, the angle formed by the oblique surface 23 and the top end face 21 is greater than 90 degrees. The oblique surface 23 forms a special geometric structure, which is convenient for CT or oral scanning imaging during implant surgery. The registration points 24 on the top end surface 21 and the beveled surface 23 are directly fixed to the patient's jaw with a connecting bracket (for details, please refer to the working process of the oral implant navigation registration component later), and a calibrated detection tool. Navigation registration can be performed, so that the surgical area and surgical instruments can be accurately and real-time displayed in the CT image on the navigation display screen, realizing precise navigation.

[0038] It should be understood that, in this embodiment, the top end surface 21 and the beveled surface 23 are respectively provided with registration points 24. The registration points 24 are distributed on the top end surface 21 and the beveled surface 23, so that the anchoring nail device can be connected to the top of the tooth ridge (such as Figure 6 ), or it can be attached buccally (as shown in Figure 7 As shown), if the support nail device is driven in from the top of the tooth ridge, it can be more compatible with the patient's bone volume, but it may hinder the implantation of the implant. If the support nail device is driven in from the buccal position, it can be more compatible with the position of the implant, but the patient's bone volume needs to be considered. In this embodiment, registration points 24 are set on the top end face 21 and the beveled surface 23. Regardless of whether the support nail device is driven in from the top of the tooth ridge or on the buccal side, there are corresponding registration points 24 for marking registration, which can realize the connection of support nail devices in different directions and angles. The specific connection method can be selected according to the patient's bone volume, so that the base 2 can play its role to a greater extent, and can take into account the different bone volumes of patients, which is more conducive to the accuracy of registration.

[0039] The top end surface 21 and the beveled surface 23 may be provided with one or more registration points 24. In some embodiments of the anchor nail device with multiple registration points of the present invention, two or more registration points 24 may be provided on each of the top end surface 21 and the beveled surface 23. Figure 2 As shown, the two registration points 24 on the top end surface 21 are arranged asymmetrically relative to the centerline of the top end surface 21; the two registration points 24 on the beveled surface 23 are arranged asymmetrically relative to the centerline of the beveled surface 23. It should be understood that the centerline referred to here includes the transverse centerline and the longitudinal centerline of the surface, that is, the two registration points 24 are arranged asymmetrically relative to the transverse centerline and the longitudinal centerline of the surface. In some specific examples, the registration points 24 can be a hemispherical concave structure or a conical socket structure to match different probe structures.

[0040] In the above embodiment, the registration points 24 on the top end surface 21 and the beveled surface 23 are asymmetrically distributed. It should be understood that if the registration points were symmetrical, the registered model would be offset. However, in this embodiment, the registration points 24 on the plane are asymmetrically distributed, which facilitates the registration of the probe tip. Furthermore, the multiple asymmetrically distributed registration points 24 on the abutment 2 allow for intraoral registration with minimal anchoring devices. For example, only two to three anchoring devices can be used to complete full-mouth registration, providing a better patient experience.

[0041] The base 2 is made of titanium alloy and its surface is sandblasted, which can improve the problem of artifacts in CT. At the same time, if you want to repair immediately after the implant surgery, you need to perform an oral scan. The metal with a reflective effect is generally not clear during the oral scan. The sandblasting treatment of the surface of the base 2 can solve this problem.

[0042] In other embodiments of the present invention, an anchoring nail device with multiple registration points is combined with Figure 3 and Figure 4 As shown, the bottom end surface 22 of the base 2 is provided with a receiving cavity 25 for receiving the head of the anchoring nail 1, and the top end surface 21 of the base 2 is provided with a first connecting hole 26, which is connected to the receiving cavity 25 and forms a connecting hole 27 at the connecting position. The aperture of the connecting hole 27 is smaller than the aperture of the first connecting hole 26 and smaller than the inner diameter of the receiving cavity 25; Figure 1 and Figure 5 As shown, a second connecting hole 11 is opened in the head of the support nail 1. The head of the support nail 1 is placed in the accommodating cavity 25, and then the fastening screw is passed through the connecting hole 27 in the first connecting hole 26 and screwed into the second connecting hole 11 to connect the head of the support nail 1 to the base 2.

[0043] Understandably, see again Figure 1 As shown, the specific structure of the anchor nail 1 mainly consists of a head, a neck, and a threaded section. The threaded section is placed in the patient's jawbone, and the neck is the connecting transition area between the head of the anchor nail 1 and the threaded section, which can serve as a drilling depth limiter. The head of the anchor nail 1 has an asymmetric polygonal structure, which facilitates the rapid installation and uniqueness of the installation position of the anchor nail 1 and the abutment 2, ensuring that the position of the abutment 2 in the patient's mouth is completely consistent during multiple disassembly and assembly before and during surgery, providing a basis for precise alignment operations in navigation surgery. The second connecting hole 11 in the head of the anchor nail 1 is used to connect the anchor nail 1 and the abutment 2 by tightening screws.

[0044] Combine Figure 1 and Figure 4 As shown, the accommodating cavity 25 of the base 2 is a polygonal groove that matches the shape of the head of the support nail 1, and adopts contact fit when installing the support nail 1; the top end surface 21 of the base 2 is provided with a first connecting hole 26, and the first connecting hole 26 and the accommodating cavity 25 are connected to form a connecting hole 27, and the connecting hole 27 forms a limiting boss at the connection between the first connecting hole 26 and the accommodating cavity 25. During installation, the support nail 1 is first driven in, and then the base 2 is inserted into the support nail 1 according to the shape of the accommodating cavity 25, and then a fastening screw is installed in the first connecting hole 26 of the base 2, and the head of the fastening screw is located above the connecting hole 27 and is limited by the connecting hole 27, and the lower part of the fastening screw passes through the connecting hole 27 to form a connection with the second connecting hole 11 of the head of the support nail 1 in the accommodating cavity 25, so that the base 2 and the support nail 1 can be connected and fixed.

[0045] During the navigational implant procedure, an appropriate number of anchor pins (1) are driven into the ridge or buccal side of the tooth to secure the implant to the patient's jawbone, ensuring maximum patient comfort. The connecting bracket retaining pins are also screwed into the patient's jawbone, and the connecting bracket is secured to the connecting bracket retaining pins. This allows the marker to be secured to the jawbone through the connecting bracket, providing a foundation for the navigational implant procedure. Based on the preoperatively planned implant position, visual markers are used for calibration and registration, and the navigational procedure begins.

[0046] The present invention also provides an oral implant navigation registration component. In some specific embodiments, see Figure 8As shown, the oral implant navigation registration component includes an anchor nail device with multiple registration points in any one of the above embodiments, and also includes a connecting bracket 3, a visual marker frame 4 and a detection tool 5. One end of the connecting bracket 3 is suitable for being fixed to the patient's oral jaw, and the other end of the connecting bracket 3 is connected to the visual marker frame 4. A first visual marker point 41 is set on the visual marker frame 4, which is used to establish a surgical area coordinate system through the first visual marker point 41; the detection tool 5 acts on the registration point 24 on the anchor nail device with multiple registration points, and is used to obtain the corresponding coordinates of the registration point 24 in the surgical area coordinate system.

[0047] During the navigation implant surgery, an appropriate number of support nail devices are driven into the top or buccal side of the patient's jaw to securely connect with the patient's jaw. One end of the connecting bracket 3 is also fixed to the patient's jaw through a fixing nail and is tightened by a locking nut. The other end of the connecting bracket 3 is connected to the visual marker frame 4. The first visual marker 41 is provided on the visual marker frame 4. In this way, the first visual marker 41 can be secured to the jaw through the connecting bracket 3, providing a basis for the navigation implant surgery. During the navigation surgery, when using the support nail device for registration, a detection tool 5 with a calibrated position is required. The detection tool 5 can be a detection tool such as an implant mobile phone drill or probe.

[0048] In some specific examples, the connecting bracket 3 is a connecting rod, and a curved portion is provided in the middle of the connecting rod to form a bend suitable for avoiding the patient's lips; one end of the connecting bracket 3 is provided with a transverse connecting hole perpendicular to the connecting bracket 3, and the visual marker frame 4 can be inserted from both sides, so that a more favorable insertion angle can be selected in different surgical areas to ensure that the visual marker is not blocked.

[0049] The other end of the connecting bracket 3 may be provided with a mounting hole, through which a fixing pin may be installed to connect and fix the end of the connecting bracket 3 to the patient's jaw. In some embodiments, a mounting bracket 31 may be provided at the end of the connecting bracket 3. The mounting bracket 31 may be bent to form a structure suitable for matching installation in the patient's mouth. Specifically, the mounting bracket 31 may be bent to form an arc that matches the dental arch so that the mounting bracket 31 fits the patient's dental arch when the connecting bracket 3 is fixed. The mounting bracket 31 is formed with a mounting hole, and a fixing pin is provided in the mounting hole to fix one end of the connecting bracket 3 to the patient's jaw via the fixing pin.

[0050] In some specific examples, the structure of the connecting bracket 3 is as follows: Figure 9 As shown, a mounting hole is provided at one end of the connecting bracket 3, and a fixing nail is provided in the mounting hole, see Figure 6 or Figure 7 As shown, using Figure 9The connecting bracket 3 shown in the figure drives the fixing pin into the top of the tooth ridge, and the fixing pin fixes the end of the connecting bracket 3 to the top of the patient's jaw bone. Figure 10 As shown, one end of the connecting bracket 3 is connected to a mounting bracket 31, a mounting hole is provided on the mounting bracket 31, and a fixing nail is provided in the mounting hole, see Figure 8 As shown, using Figure 10 The connecting bracket 3 shown is driven with a fixing pin from the buccal side to the lingual side of the patient. The fixing pin secures the end of the connecting bracket 3 to the side of the patient's jaw. Specifically, the mounting frame 31 forms the same curvature as the patient's dental arch, ensuring a snug fit. The mounting frame 31 and the connecting bracket 3 can be fixedly connected by welding or other methods. The mounting frame can be made of thin stainless steel for easy bending.

[0051] The mounting hole on the mounting frame 31 connected to one end of the connecting bracket 3 is used to fix the bracket 3 to the patient's jaw through a fixing pin. The mounting hole on the mounting frame 31 can be one, that is, it can complete the connection and fixation with the patient's jaw. In some examples, the mounting hole on the mounting frame 31 can be at least two, combined with Figure 8 and Figure 10 As shown, when the patient has osteoporosis, after using one mounting hole to complete the fixed connection, the connection position may be offset due to osteoporosis. At this time, a two-hole or multi-hole mounting frame 31 can be used to ensure the effective connection and fixation of the connecting bracket 3 and the patient's jaw.

[0052] It is understood that the specific combination of the connecting bracket 3, the visual marking frame 4, and the support nail device can be seen in Figure 8 As shown, the visual marking frame 4 can be designed into various shapes. In some examples, the visual marking frame 4 includes a straight connecting rod 42 and a marking frame. Figures 6 to 8 The main body is in the shape of a grid, one end of the straight connecting rod 42 is connected to the horizontal connecting hole of the connecting bracket 3, and the other end is connected to the marking frame. The marking frame is provided with a plurality of first visual marks 41, and the distances between the first visual marks 41 are dispersed. The detection tool 5 can be a detection tool such as a planting mobile phone drill or a probe. Specifically, it can be used as Figure 11The detection tool 5 shown serves as a detection tool and includes a marking area and a detection area. The marking area is provided with a plurality of second visual markers 51, which are dispersed between the second visual markers 51. The detection area is provided with a detection head 52, which is adapted to the shape of the registration point 24 and is suitable for the detection head 52 to be embedded with the registration point 24. In some specific examples, the registration point 24 is a concave conical socket structure, and the detection head 52 is a conical tip. During detection, the conical tip of the probe is brought into contact with the conical socket structure of the anchor pin in a vertical direction. In other examples, the shape of the detection area detection head 52 is a convex circle corresponding to the hemispherical concave structure of the registration point 24 on the support nail device. During detection, the convex circle and the hemispherical concave structure need to be completely embedded to align the center detection point of the detection area of ​​the detection head 52 with the center point of the hemispherical concave of the registration point 24. After determining the positions of multiple registration points 24 on the support nail devices one by one, the conversion relationship between the CT virtual space and the actual surgical area can be found, so that the patient's surgical area and surgical instruments can be accurately and real-time displayed in the CT image on the navigation display screen, thereby achieving precise navigation.

[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
