Embodiment 1

[0049] Taking the front of the jaw as a frame of reference, the side of the orthognathic plate close to the jaw is the medial side, and the side away from the jaw is the outer side. Such as Figure 1a-2 As shown, the connecting strut of the orthognathic bone plate includes a first round hole extension, a second round hole extension and a bending plate 3, the first round hole extension is located below the second round hole extension and is located in the second circle On the front side of the hole extension part, the bending plate 3 is connected between the upper and lower round hole extension parts, and the round hole extension part is composed of a plurality of round hole parts 1 connected by connecting pieces. The middle connecting plate 4 is V-shaped, and the curved surface of the inner surface of the middle connecting plate is adapted to the shape of the curved surface of the jawbone, so that the inner surface of the middle connecting plate can fit the surface of the jawb...

Embodiment 2

[0057] Such as Figure 3a-4 As shown, the structure of the orthognathic osteosynthesis plate described in this embodiment is substantially the same as that of the orthognathic osteosynthesis plate in Embodiment 1. The difference from Embodiment 1 is that the bending plate 3 of each connecting strut plate in this embodiment The first bending portion 31 has a large degree of bending, and the connecting portion 32 of the bending plate 3 is relatively long. For the two connecting support plates close to the middle connecting plate 4, the length of the connecting piece between the round hole 1 closest to the middle connecting part 4 and its adjacent round hole 1 in the first round hole extension part is longer than the other The length of the connecting piece between adjacent round hole parts 1.

Embodiment 3

[0059] Such as Figure 5a-6 As shown, the structure of the orthognathic bone plate described in this example is substantially the same as that in Example 2, and the difference between Example 3 and Example 2 is that in this example, the bends of the connecting struts The first bending portion 31 of the folding plate 3 is bent outwards with a small degree of curvature. In each connecting support plate, in the first round hole extension portion, the length of the connecting piece between each round hole portion 1 is the same.

[0060] Such as figure 2 , Figure 4 with Image 6 As shown, before using the orthognathic bone plate of the present invention, the skull needs to be divided, that is, divided into the main body part 5 of the jaw and the divided part 6 of the jaw, which needs to be divided using a surgical guide plate. The structure of the specific surgical guide plate is as follows: Figure 7 As shown, the surgical guide plate includes a bone tissue fitting part 7 i...

Abstract

The invention discloses a straight jaw bone plate and a manufacturing method thereof. The bone plate comprises a plurality of connecting support plates, a middle connection plate and disconnectable connection parts, wherein the left end and the right end of the middle connection plate are connected with two connecting support plates through the disconnectable connection parts, and every two adjacent connecting support plates are connected through one disconnectable connection part. Each connecting support plate comprises a first round hole extending part, a second round hole extending part anda bending plate, wherein the bending plate is connected between the first round hole extending part and the second round hole extending part, the hook faces on the inner side surfaces of the first and second round hole extending parts are matched with the hook face on the surface of the jaw bone in shape, and the whole straight jaw bone plate is integrally formed through 3D printing. The straightjaw bone plate is manufactured through 3D printing, the bone plate can perfectly fit to the jaw bone, the surgical operation difficulty can be reduced, operational processes in a surgery are reduced,the time of the surgery is shortened, and wound and pain of a patient are reduced.

Description

technical field [0001] The invention relates to an orthognathic bone plate and a manufacturing method thereof, belonging to the field of medical devices. Background technique [0002] Orthognathic surgery is usually performed to correct related facial structures or to correct orthodontic problems. The doctor needs to use an articulator to align the teeth and fix the upper and lower jaws with steel wires. After the doctor completes the cut, he uses multiple small orthognathic bone plates to connect and fix At the cut site, these small orthognathic bone plates need to be manually shaped during the operation, and finally the steel wire is removed to take out the occlusal plate. At present, the Chinese patent discloses an implant for orthognathic surgery. (Publication No.: CN105147374A) uses CT scan to obtain the bone data of the patient. The doctor designs a plan based on the CT data, and uses a milling machine to make a guide plate for cutting and positioning and a guide plate...
