[0025] Example

[0026] like Figure 1 , Figure 2 river Figure 3 As shown, an embodiment of the present application provides a guide plate 100 for fibula osteotomy and implant placement. The guide plate 100 for fibula osteotomy and implant placement includes a body 110 and a connection structure 120 .

[0027] The main body 110 has a first surface, and the first surface contains a first through hole 111. That is, the first through hole 111 located in the main body 110 runs through the first surface. The first surface is used to fit the front of the fibula. When the first surface fits the front of the fibula, the first through hole 111 is used for the implant to pass through, that is, the implant can be fixedly connected to the fibula using the first through hole 111. The main body 110 also has a plurality of thick cutting channels 112, and the thick cutting channels 112 and the first through hole 111 are spaced apart. The thick cutting channels 112 are used to guide the cutting blade to move along its guiding direction. Specifically, the thick cutting channel 112 has two inner walls, which are arranged opposite to each other. The interval between the two inner walls is small, and only a blade can pass through. When the fibula is cut off, the blade is placed into the thick cutting channel 112, and the thick cutting channel 112 can be used to limit the movement direction of the blade, thereby accurately cutting the fibula.

[0028] The connecting structure 120 is fixedly connected to the body 110, and the connecting structure 120 is used to connect to the fibula. Specifically, the connecting structure 120 and the body 110 can be an integral structure to ensure the connection strength between the two; the connecting structure 120 and the body 110 can also be fixedly connected by bonding; the connecting structure 120 and the body 110 can also be fixedly connected by a structure such as a screw.

[0029] The guide plate 100 for fibula osteotomy and implant implantation provided in the embodiment of the present application includes a main body 110 and a connecting structure 120. The main body 110 has a first through hole 111, and the first through hole 111 is used for the implant to pass through; the main body 110 also has a plurality of thick cutting channels 112, and the thick cutting channels 112 and the first through hole 111 are spaced apart, and the thick cutting channels 112 are used to guide the cutting blade to move along its guiding direction; the connecting structure 120 is fixedly connected to the main body 110, and is used to be fixedly connected to the fibula. The first through hole 111 can control the implant preparation channel, which is conducive to the precise implantation of the implant; the thick cutting channel 112 can limit the direction of the cutting blade, which is conducive to the precise truncation of the fibula; the connecting structure 120 can fix the main body 110 to the fibula. Therefore, the fibula osteotomy and implant implantation can be completed in the same operation, which reduces the time of the patient's edentulous state, improves the accuracy of implant implantation, and is conducive to the smooth placement of the restored dentition.

[0030] In some embodiments of the present application, the first through hole 111 penetrates the body 110 along a first direction, and the first direction is parallel to the guide plane of the thick cutting channel 112. Specifically, the guide plane of the thick cutting channel 112 is the plane where the inner wall of the thick cutting channel 112 is located. That is, the penetration direction of the first through hole 111 is parallel to the inner wall of the thick cutting channel 112. The first direction can be a direction perpendicular to the fibula. In this case, the implant can be implanted into the fibula through the first through hole 111 in a direction perpendicular to the fibula, and the cutting blade can cut off the fibula through the thick cutting channel 112 in a direction perpendicular to the fibula.

[0031] In some embodiments of the present application, a plurality of thick cutting paths 112 may be provided, and the plurality of thick cutting paths 112 may be spaced apart to facilitate the truncation of the fibula at a plurality of different positions.

[0032] In some embodiments of the present application, a plurality of first through holes 111 may be provided to facilitate implantation of a plurality of implants. The plurality of first through holes 111 may be spaced apart to facilitate sequential implantation of a plurality of implants.

[0033] In some embodiments of the present application, the body 110 also has a second surface, which is adjacent to the first surface, and the second surface is used to fit the outer side of the fibula. The second surface contains a second through hole 121 and the front side of the thick cutting channel 112, that is, the blade extends into the thick cutting channel 112 through the second surface, so that the blade can cut the fibula. The second through hole 121 is located on the connecting structure 120, and the second through hole 121 is used for screws to pass through to be fixedly connected to the fibula. The axial direction of the second through hole 121 is perpendicular to the first direction, and is spaced apart from the first through hole 111. That is, the screw can be inserted from the outer side of the fibula into the fibula using the second through hole 121 to fix the connecting structure 120 to the fibula.

[0034] In some embodiments of the present application, the body 110 further has a third surface, and the body 110 has a third through hole 122, which runs through the third surface and is used for screws to pass through. The third surface is used to fit the back of the fibula. When the third surface fits the back of the fibula, the screw can be inserted into the fibula by using the third through hole 122 to fix the connection structure 120 to the fibula.

[0035] In some embodiments of the present application, the third through hole 122 and the first through hole 111 are spaced apart, and the third through hole 122 and the thick cut channel 112 are spaced apart. Specifically, the third through hole 122 is located on the side of the first through hole 111 away from the second through hole 121. The axial direction of the third through hole 122 can be parallel to the first direction, that is, when the third surface is attached to the back of the fibula, the screw can be inserted into the fibula perpendicularly to the direction of the fibula through the third through hole 122 to fix the connection structure 120 to the fibula.

[0036] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
