The above-mentioned patent is only applicable to the mandible and chin, and its traction method is wire traction.

SUMMARY OF THE INVENTION

The technical problem to be solved by the present invention is to provide an adjustable arc-shaped forehead model guide plate, so as to facilitate the selection of an arc-shaped bone plate with a corresponding shape during surgery to reconstruct the shape of the forehead.

The technical problem of the present invention is solved by the following solutions: an adjustable arc-shaped forehead mode guide plate, which is composed of a forehead orbital belt guide rail and a segmented mode forehead plate, wherein:

The described frontal-orbital belt guide rail uses the strip-shaped frontal-orbital belt of the frontal-orbital part as the guide rail of the template, and the radian of the frontal-orbital belt guide rail refers to the radian of the frontal-orbital part of normal children;

The mode frontal plate is connected to the orbital belt rail by sliding connectors, including the left and right mode frontal plate and the central mode frontal plate. The forehead is equivalent to the forehead of a 1-year-old child. With the increase of age, when the forehead expands, the left and right model frontal plates are separated along the forehead orbital guide rail, and the central model forehead plate is moved through the guide rail to supplement the arc of the forehead in the middle part. Make it a whole forehead.

On the basis of the above scheme, in order to adapt to different age groups, the front-orbital belt guide rail is retractable and used to adjust the length.

The radian of the fronto-orbital belt guide rail refers to the radian of the frontal-orbital part of normal children, including the statistical average of normal people aged 1, 3, 5, 8, 16 and 18 years old.

The advantages of the present invention are: it is convenient for doctors to design the cutting and arrangement of bone flaps according to the shape of the forehead constructed by the adjustable curved forehead pattern guide plate, and use the bone flaps with the shape and curvature to reconstruct the bony structure of the forehead, thereby improving the operation efficiency. quality.

Detailed ways

Figure 1 is a schematic diagram of the structure of the present invention and a schematic diagram of the frontal orbital belt guide rail shown in Figure 2: an adjustable curved forehead pattern guide plate, which is composed of a frontal orbital belt guide rail 1 and a segmented pattern frontal plate 2, wherein:

The described frontal orbital belt guide rail 1 uses the strip-shaped frontal orbital belt of the frontal orbital part as the guide rail of the template, the frontal orbital belt rail guide rail can be telescopically adjusted in length, and the radian of the frontal orbital belt guide rail 1 refers to the frontal orbital radian of normal children;

The mode frontal plate 2 is connected to the frontal orbital belt guide rail 1 by the sliding connector 3, including the left and right mode frontal plates A, B and the central mode forehead plate C, the left and right mode frontal plates A, B radians and The curvature of the orbital belt guide rail 1 is matched. When closed, the overall forehead is equivalent to the forehead of a 1-year-old child. As the age increases, when the forehead expands, the left and right frontal plates A and B are separated by the orbital orbital belt guide rail 1. The central model forehead plate C is moved through the guide rail, and the arc of the forehead in the middle part is supplemented to form a whole forehead.

The invention uses the strip-shaped frontal-orbital belt of the frontal-orbital part as the guide rail of the template, and the segmented arc-shaped forehead part as the design main body, wherein the radian of the frontal-orbital belt guide rail refers to the radian of the frontal-orbital part of normal children.

The radian of the frontal-orbital belt guide rail refers to the radian of the frontal-orbital part of normal children, including normal values in the age group of 1, 3, 5, 8, 16, and 18 years old; the segmented arc forehead includes three parts : The left and right mode frontal plates A and B radians match the radian of the forehead orbital belt guide rail 1. When closed, the overall forehead is equivalent to the forehead of a 1-year-old child. When the forehead of different ages is enlarged, the frontal plate A can be separated through the guide rails. , B, and the central model forehead plate C is moved through the guide rails to supplement the arc of the forehead in the middle part to make it connect to the whole forehead.

According to the age of the child, the invention pulls out the guide rail with adjustable length to adapt to the curvature and length of the frontal-orbital belt of children of different ages, so as to facilitate the doctor to reassemble the patient's frontal-orbital belt as a template.
