Abstract
Description
Technical Field
[0001] This utility model relates to the field of oral medical device technology, and in particular to a device for measuring the angle of a surgical guide plate for oral implantation. Background Technology
[0002] A dental implant surgical guide is a three-dimensional tool that is customized according to the patient's oral anatomy. It is usually made of transparent resin or medical-grade plastic and looks like a thin and precise "oral template". The surface of the guide has multiple cylindrical guide holes / guide channels with the diameter matching the implant drill bit.
[0003] There is often a gap between the implant and the surgical guide channel to ensure compatibility, but this gap weakens the guide's ability to restrain the implant to some extent. When there is a fresh socket or a tough alveolar ridge in the surgical area, the implant may still tilt in the guide channel, thereby reducing surgical precision and posing surgical risks such as nerve and blood vessel damage and bone wall perforation.
[0004] Patent document with announcement number (CN222426276U) discloses an oral surgery guide angle measuring device, including: a measuring ruler with a slot on its side; two angle reading mechanisms, respectively disposed on both sides of the slot and mounted on the surface of the measuring ruler; wherein, the angle reading mechanism includes a reading component disposed inside the measuring ruler, and a sliding component is disposed on one side of the reading component and mounted on the surface of the measuring ruler; the above-mentioned oral surgery guide angle measuring device can measure the angle of oral implantation surgery under the action of the angle reading mechanism. The device can directly view and record the specific value when the fitting plate is close to the rubber elastic rope, so that the implantation angle positioning measuring ruler can directly read the angle value.
[0005] When using the above-mentioned technology, the following technical problems were found in the existing technology: it can only measure the angle in one direction specifically, making it difficult to apply to all angle situations of dental implants; in addition, because the surgical guide for dental implantation is irregularly shaped like teeth, it is not easy to stably place the measuring device on the guide, making it difficult to accurately measure the angle at which the guide channel is opened on the guide. Therefore, a surgical guide angle measuring device for dental implantation is designed to provide an alternative technical solution to the above-mentioned technical problems. Utility Model Content

[0036] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0037] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.
[0038] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.
[0039] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0040] like Figure 1 As shown, this dental implant surgery guide angle measuring device includes a base 1 and an implant guide 2. It should be noted that the implant guide 2 in the figure is only for illustration. In reality, it is an oral template with a certain curvature along the teeth of the upper or lower jaw (similar to the structure of a transparent dental crown). One or more guide channels 21 are opened on the implant guide 2. The guide channel 21 is used to guide the implant drill to make a hole in the corresponding alveolar bone. After the hole is made, the implant is placed. Therefore, the angle of the guide channel 21 determines the angle of implant placement. If the implant is not placed in the alveolar bone at the actual angle, it will lead to surgical risks such as nerve and blood vessel damage and bone wall perforation. Based on the above, this device is used to measure the angle of the guide channel 21 on the implant guide 2.
[0041] The device also includes a first protractor 3, a second protractor 4, a pointing component 5, a guide rod 6, and two fixing mechanisms 7. The two fixing mechanisms 7 are respectively located on the bottom sides of the base 1. The fixing mechanisms 7 are used to stably place the base 1 on the planting guide plate 2 of any arc and size, providing an accurate reference for subsequent measurement of the angle of the guide channel 21.
[0042] The first protractor 3 and the second protractor 4 are rotatably connected to the base 1 in an alternating manner along the first direction and the second direction, respectively. The first direction is the length direction of the base 1, and the second direction is the width direction of the base 1. They are also intersected with each other in the vertical direction. The construction of the first protractor 3 and the second protractor 4 is as described in the prior art, including but not limited to the fact that they are coated with standard scale lines and are made of iron or plastic.
[0043] The pointing component 5 is located between the first protractor 3 and the second protractor 4, and the guide rod 6 is located at the bottom of the pointing component 5. The guide rod 6 is used to insert into the guide channel 21. When the guide rod 6 is fully inserted into the guide channel 21, it can drive the pointing component 5 and the first protractor 3 to rotate on the second protractor 4, and drive the pointing component 5 and the second protractor 4 to rotate on the first protractor 3. This changes the position of the pointing component 5 on the first protractor 3 and the second protractor 4 respectively. The scale values of the pointing component 5 at the corresponding positions on the first protractor 3 and the second protractor 4 are read to obtain the angle values of the guide channel 21 in two directions on the planting guide plate 2. The required opening angle is determined by these values to determine whether there is an error.
[0044] Furthermore, such as Figure 2 As shown, and for reference Figure 1The base 1 has a first hollow 11 in the middle, which is used to accommodate the guide rod 6 on the pointing component 5 so that the guide rod 6 can enter the guide channel 21 without being blocked by the base 1, and the guide rod 6 can rotate and adjust according to the angle of the guide channel 21.
[0045] A set of first hinge bodies 12 and a set of second hinge bodies 13 are fixed on the base 1 along the first direction and the second direction (see above). The first protractor 3 is rotatably connected between the set of first hinge bodies 12. The second protractor 4 has a second hollow 41 in the middle, which is used to accommodate the first protractor 3. The second protractor 4 is staggered with the first protractor 3 and has two free ends. The second protractor 4 is rotatably connected between the set of second hinge bodies 13 through its free ends. It should be noted that the connection between the first protractor 3 and the second protractor 4 and the first hinge body 12 and the second hinge body 13 is achieved by damping washer to achieve damped rotational connection. Under the action of this damped rotational connection, the rotation angle of the first protractor 3 and the second protractor 4 can be maintained and suspended.
[0046] The fixing mechanism 7 includes a first sliding group 71 arranged along a first direction, a second sliding group 72 arranged along a second direction and integrated with the first sliding group 71, and a gripper 73 disposed on the second sliding group 72. With the combination of the first sliding group 71 and the second sliding group 72, the gripper 73 can be adjusted in a small range of front-back and left-right positions, so as to align with the planting guide plate 2 of any arc size. The gripper 73 can elastically expand its opening, so that the gripper 73 opens and partially wraps around and fixes itself on the part of the planting guide plate 2, thereby limiting the base 1 to the planting guide plate 2.
[0047] like Figure 3 As shown, and for reference Figure 2 and Figure 1 The pointing component 5 includes two first finger plates 51 that are integrally connected and rotatably connected to the first protractor 3, two second finger plates 52, and a connecting frame 53 fixed between the first finger plates 51 and the second finger plates 52; wherein the first finger plates 51 are used to indicate the scale value lines on the first protractor 3, and the second finger plates 52 are used to indicate the scale value lines on the second protractor 4.
[0048] Based on the above, the rotating connection of the first protractor 3 and the center of the second protractor 4 are on the same horizontal axis extending in the first direction; the rotating connection of the second protractor 4 and the rotating connection of the first finger plate 51 are on the same horizontal axis extending in the second direction. Therefore, when the guide rod 6 drives the first protractor 4 to rotate at the first hinge 12 through the pointing component 5, it will cause the second finger plate 52 to rotate based on the central axis of the second protractor 3, causing the scale value indicated by the second finger plate 52 on the second protractor 4 to change, that is, to obtain the angle measurement value in one direction. In addition, when the guide rod 6 drives the second protractor 4 to rotate at the second hinge 13 through the pointing component 5, it will cause the second finger plate 52 to rotate based on the central axis of the second protractor 4, causing the scale value indicated by the first finger plate 51 on the first protractor 3 to change, thereby obtaining the angle measurement values in two directions, so as to be as applicable as possible to all situations where dental implant angles are measured.
[0049] The guide rod 6 is fixed or detachable, preferably detachable and located at the bottom of the connection between the two first finger plates 51. The guide rod 6 is selected according to the diameter of the guide channel 21 so that it can be inserted into the guide channel 21 to transmit the opening angle of the first finger plate 51 and the second finger plate 52 relative to the base 1.
[0050] Furthermore, the top of the guide rod 6 is integrally connected to a connector, which is fixed to the bottom of the connection between the two first finger plates 51 by an angle iron bolt assembly, so that the guide rod 6 can be detached from the connection between the two first finger plates 51.
[0051] like Figure 4 As shown, and for reference Figure 1 and Figure 2 The first sliding group 71 and the second sliding group 72 are both composed of a groove 711 and a slider 712 disposed in the groove 711; thus, the slider 712 can slide back and forth along the length of the groove 711 in the groove 711, and the slider 712 of the first sliding group 71 is fixed to the groove 711 of the second sliding group 72, so that the range of movement of the gripper 73 is not limited to the sliding range of the first sliding group 71, but to the sliding range formed by the superposition of the first sliding group 71 and the second sliding group 72, so that it can be fixed on the planting guide plate 2 of any arc size.
[0052] Furthermore, such as Figure 5 As shown, and for reference Figure 4 The gripper 73 is detachable and angle-adjustable on the slider 712 of the second sliding group 72. Specifically, both the slider 712 and the gripper 73 of the second sliding group 72 are provided with screw holes 713, and the two screw holes 713 are threaded together with screws 714 that can connect the gripper 73 and the slider 712 into one piece.
[0053] It should be noted that the gripper 73 can be made into multiple sizes that are successively enlarged or reduced. However, regardless of the size, the screw hole 713 on it is preferably adapted to the screw hole 713 on the slider 712. Thus, a gripper 73 that is approximately suitable for the size of the planting guide plate 2 can be selected and connected to the slider 712 by screws 714. The angle of the gripper 73 on the slider 712 is determined and rotated. Finally, the screws 714 are tightened while maintaining the angle of the gripper 73 on the slider 712 to fix the angle of the gripper 73 on the slider 712. For example, the gripper 73 is at an oblique angle on the slider 712 so as to contact and fix it on the slightly oblique part of the planting guide plate 2. In this way, it can be fixed on any planting guide plate 2.
[0054] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the present utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of the present utility model, thereby enabling those skilled in the art to better understand and utilize it. The present utility model is limited only by the claims and their full scope and equivalents.
