Description

Technical Field

[0001] The present application relates to the technical field of dental implant surgery auxiliary tools, and in particular to a superimposed guide plate. Background Art

[0002] Dental implant surgery is the process in which a dentist places an implant in the patient's mouth and then attaches a denture to the implant.

[0003] The implant guide is a tool that assists doctors in inserting implants. It mainly includes a guide body and a guide tube. The shape of the guide body matches the alveolar bone, and a through hole is provided on the guide body, in which the guide tube is embedded. The guide tube can guide the drill bit, making it easier for doctors to implant implants on the alveolar bone.

[0004] During the actual operation, patients with high alveolar bones are often encountered. Such patients need to have their alveolar bones flattened. During the flattening process, doctors often cut according to their own experience. The thickness of the cutting is not easy to control, which prolongs the effect of dental implants and the time spent in the implant process. Utility Model Content

[0005] In order to improve the effect of dental implants and shorten the operation time, the present application provides a superimposed guide plate.

[0006] The present application provides a stacking guide plate adopting the following technical solution:

[0010] By adopting the above technical solution, after the alveolar bone is flattened, the disassembly part can be immediately installed on the fixing part, and then under the action of the guide tube, a hole can be opened on the alveolar bone to implant the implant.

[0011] Optionally, the disassembly portion is provided with a latch, the fixing portion is provided with a socket, and the latch is plugged into the socket.

[0012] By adopting the above technical solution, a detachable connection between the detachable part and the fixed part is achieved through the cooperation of the latch and the socket.

[0013] Optionally, a positioning block is provided on the disassembly portion, a positioning groove is correspondingly provided on the fixing portion, and the positioning block is embedded in the positioning groove.

[0014] By adopting the above technical solution, through the cooperation between the positioning block and the positioning groove, the disassembly part is prevented from being displaced in a direction parallel to the reference plane after being connected with the fixing part.

[0015] Optionally, a locking assembly is provided on the latch, and the locking assembly includes a limit block, which is installed on the latch and can move in a direction perpendicular to the latch, and a limit groove is provided on the side wall of the socket, and one side of the limit block can be inserted into the limit groove.

[0016] By adopting the above technical solution, the bolt is inserted into the insertion hole to realize the connection between the disassembly part and the fixed part. The limit block is moved so that one side of the limit block is inserted into the limit groove, so that the movement of the bolt can be limited, the disassembly part and the fixed part are blocked, and the stability of the connection between the disassembly part and the fixed part is improved.

[0017] Optionally, a plurality of the limit blocks are evenly spaced along the circumference of the latch.

[0018] By adopting the above technical solution, multiple limit blocks limit the latch at the same time, further improving the stability of the disassembly part and the fixing part after installation.

[0019] Optionally, the locking assembly further includes a driving member, which is rotatably connected in the latch, and the plurality of limit blocks are all connected to the driving member, and rotating the driving member can drive the limit blocks to move outside the latch.

[0020] By adopting the above technical solution, after the pin is inserted into the socket, the driving member is rotated, and the driving member drives multiple limit blocks to be synchronously inserted into the limit grooves, thereby further improving efficiency and shortening operation time.

[0021] Optionally, the rotation axis of the driving member is parallel to the latch pin, the driving member is provided with a driving inclined surface, the limiting block is provided with an abutment member, and the abutment member abuts against the driving inclined surface.

[0022] By adopting the above technical solution, the driving member is rotated, and the abutting member abuts on the driving inclined surface and slides, thereby driving the limit block to move in a direction away from the latch.

[0023] Optionally, the locking assembly further comprises an elastic member, and the elastic member is used to enable the limit block to maintain a tendency to rotate in a direction close to the driving member.

[0024] By adopting the above technical solution, when the disassembly part needs to be disassembled, the driving member is rotated, and the limit block can automatically escape from the limit groove under the action of the elastic member, thereby facilitating the separation of the disassembly part from the fixed part.

DETAILED DESCRIPTION

[0033] The following is combined with Figure 1-4 This application is described in further detail.

[0034] An embodiment of the present application discloses a stacked guide plate.

[0035] Reference Figure 1A superimposed guide plate includes a fixing portion 1, a receiving groove 12 is provided on one side of the fixing portion 1, and the receiving groove 12 passes through the fixing portion 1. A reference plane 11 is provided on the fixing portion 1, and the reference plane 11 is perpendicular to the penetration direction of the receiving groove 12. When the superimposed guide plate is used, the fixing portion 1 is sleeved on the outside of the alveolar bone and is tightened by a screw (not shown in the figure). The alveolar bone is penetrated in the receiving groove 12. In the process of cutting the alveolar bone, the doctor flattens the alveolar bone in comparison with the reference plane 11, which provides a reference for the doctor, shortens the operation time, and improves the effect of implant placement.

[0036] Reference Figure 1 The stacked guide plate also includes a disassembly portion 6, which is detachably connected to the reference plane 11. The disassembly portion 6 is used to block the side of the receiving groove 12 close to the reference plane 11. The disassembly portion 6 is provided with a through hole that penetrates in a direction perpendicular to the reference plane 11. A guide cylinder 2 is provided in the through hole, and the guide cylinder 2 is bonded to the side wall of the through hole. After the alveolar bone is flattened, the disassembly portion 6 is installed on the fixing portion 1. Then, the doctor can make a hole in the alveolar bone with the help of the guide cylinder 2 to implant the implant.

[0037] Reference Figure 1 , a latch 3 is integrally formed on the side of the disassembly part 6 close to the fixed part 1, and a socket 31 is provided on the reference surface 11 at a position corresponding to the latch 3. The latch 3 is inserted into the socket 31 to achieve a detachable connection between the disassembly part 6 and the fixed part 1. In order to improve the stability of the disassembly part 6 after being connected to the fixed part 1, a positioning block 4 is further provided on the side of the disassembly part 6 close to the fixed part 1, and a positioning groove 41 is provided on the reference surface 11 at a position corresponding to the positioning block 4. The positioning block 4 is embedded in the positioning groove 41 to prevent the disassembly part 6 from moving in a direction parallel to the reference part. In order to further improve the stability of the disassembly part 6 after being connected to the fixed part 1, a plurality of positioning blocks 4 can be provided, and two are provided in the present embodiment.

[0038] The implementation principle of a superimposed guide plate in the embodiment of the present application is as follows: during the implant surgery, the fixing part 1 is sleeved on the outside of the alveolar bone, and then the alveolar bone is cut using a cutting tool. During the cutting process, the reference plane 11 is used as a reference, and there is no need to repeatedly measure based on experience, thereby increasing the cutting speed and shortening the operation time. After the alveolar bone cutting is completed, the disassembly part 6 is installed on the fixing part 1, and the implant placement step can be performed.

[0039] Example 2

[0040] Reference Figure 2 and Figure 3The difference between this embodiment and the first embodiment is that in this embodiment, a locking assembly 5 for limiting the movement of the bolt 3 is provided on the bolt 3, and the locking assembly 5 includes a limit block 51. A slide groove 56 communicating with the inside of the bolt 3 is provided on the side wall of the bolt 3. The limit block 51 is connected to the side wall of the slide groove 56 and can slide in a direction perpendicular to the length direction of the bolt 3. A limit groove 55 is provided on the side wall of the socket 31 corresponding to the limit block 51. The movement of the limit groove 55 can make one side of the limit block 51 inserted into the limit groove 55, thereby preventing the bolt 3 from being separated from the inside of the socket 31, and further improving the stability after the disassembly part 6 is connected to the fixing part 1. A plurality of limit blocks 51 can be evenly spaced along the circumference of the bolt 3, and three are provided in this embodiment.

[0041] Reference Figure 2 and Figure 3 The locking assembly 5 further includes a driving member 52, which is used to drive the limit block 51 to move. The driving member 52 is a cylindrical structure, and a cylindrical rotating hole is opened on the latch 3. The rotating hole passes through the latch 3 and the disassembly portion 6, and the driving member 52 is coaxially rotatably connected in the rotating hole. Figure 4 The driving member 52 is provided with a plurality of driving inclined surfaces 521 corresponding to the limiting block 51. The driving inclined surfaces 521 are inclined along the circumference of the driving member 52 in a direction close to its own axis, and a avoiding groove 522 is formed on the side of the driving member 52. The limiting block 51 is provided with an abutment member 53, which is a hemispherical structure and is welded on the side of the limiting block 51 close to the driving member 52. After the abutment member 53 abuts against the driving inclined surfaces 521, the rotating driving member 52 can drive the abutment member 53 to move in a direction away from the driving member 52, thereby driving the limiting block 51 to move toward the inside of the limiting groove 55, thereby limiting the latch 3.

[0042] Reference Figure 2 and Figure 3 The locking assembly 5 further includes an elastic member 54, which is a sheet-like structure and is made of elastic metal. One side of the elastic member is bonded to the side wall of the slide groove 56, and the other side is bonded to the limit block 51. The elastic member is used to keep the limit block 51 moving toward the driving member 52. The driving member 52 is rotated, and after the avoidance groove 522 and the abutment member 53 are positioned correspondingly, the abutment member 53 enters the avoidance groove 522, and the limit block 51 is separated from the limit groove 55, thereby realizing the disassembly of the disassembly portion 6.

[0043] Reference Figure 2 and Figure 4 The side of the driving member 52 away from the fixing part 1 extends to the outside of the disassembly part 6, and a rectangular groove 57 is provided on the end surface of the driving member 52 away from the fixing part 1. When installing or disassembling the disassembly part 6, a screwdriver can be inserted into the rectangular groove 57 to rotate the driving member 52.

[0044] The implementation principle of a superimposed guide plate in the embodiment of the present application is as follows: after the alveolar bone is flattened, the disassembly portion 6 is aligned with the reference surface 11, and then the plug 3 is inserted into the insertion hole 31. Then the driving member 52 is rotated, and the limiting block 51 can be driven to move away from the driving member 52 under the action of the driving inclined surface 521, so that the limiting block 51 is inserted into the limiting groove 55, blocking the plug 3 from moving relative to the fixing portion 1, thereby further improving the stability of the disassembly portion 6 after installation.

[0045] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
