Embodiment Construction

[0028] Exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted, obviously, that . All examples given and discussed herein are some, but not all, embodiments of the invention. The description thereof is actually only illustrative, and is only used for explaining the present invention, and should not be construed as limiting the present invention.

[0029] Such as figure 1 As shown, in the present embodiment, a method of internally fixed fibular reconstruction of the mandible is provided, the method comprising:

[0030] S1. Collect imaging data of the jaw and fibula at the target position; wherein, the imaging data is usually DICOM standard format data obtained by CT scanning, including the shape of the bone marrow cavity of the fibula, the diameter of the bone marrow cavity and the extent of the lesion;

[0031] S2. Establishing a three-dimensional data model based on the imaging data;

Abstract

The invention discloses an internal fixation fibula reconstruction mandible method. The method comprises the following steps: acquiring iconography data of a jaw and a fibula at a target position; establishing a three-dimensional data model; performing mandible focus excision through virtual design, and determining a fibula osteotomy scheme; designing and manufacturing a fibula far-end bone fracture plate and an intramedullary fixing device; implanting the internal fixing device into a fibula marrow cavity, and connecting the fibula section with the internal fixing device. According to the internally-fixed fibula reconstruction lower jawbone method, personalized intramedullary fixation is adopted according to the osteotomy scheme and the shape and the diameter of the marrow cavity, so thatlower jawbone reconstruction is more accurate, and wounds caused by a secondary operation are reduced.

Description

technical field [0001] The invention relates to the technical field of medical appliances, in particular to an internally fixed fibula reconstruction mandible method. Background technique [0002] After segmental resection of the mandible, the mandible is often repaired with an autologous vascularized peroneal muscle flap. Oral and maxillofacial surgery for this kind of disease is a kind of more complicated operation. The method of removing one or several wedge-shaped bone blocks from the linear fibula is often used to splice the fibula into a contour similar to the original mandible. With the application of computer-assisted surgery, it is possible to accurately construct the ideal shape of the new mandible. The existing fibula reconstruction mandible method has the following deficiencies or disadvantages: [0003] a) The fibula was shaped empirically and fixed with a titanium plate. The accuracy of shaping is not high, and it is difficult to achieve the ideal effect in ...
