Embodiment

[0033] The following is attached Figure 1-3 The present invention is described in further detail.

[0034] A guide plate for jaw bone transplantation in place, which is mainly used in mandible repair surgery. Before processing the guide plate, the patient’s jaw defect is scanned first, and medical software is used to perform three-dimensional reconstruction of the jaw bone and ilium model. The three-dimensional model of the ilium is moved to the lesion position of the jaw bone to replace the original lesion of the jaw bone. By adjusting the position, angle, and length of the ilium bone model, the most matching segment of the ilium bone is found to be grafted bone 1, and an ideal surgical plan is designed, namely Carry out 3D modeling of the guide plate, and import it into the 3D printer to process the required guide plate.

[0035] Such as figure 1 and figure 2As shown, the guide plate for jaw bone transplantation in this embodiment includes a guide plate body 3, and the ...

Abstract

The present invention relates to a jaw bone transplantation in-place guide plate. The jaw bone transplantation in-place guide plate comprises a guide plate body, the guide plate body comprises a mainplate and a plurality of positioning parts located on an inner side of the main plate, wherein, a plurality of the positioning parts are fixed to a mandible stump bone and a transplantation bone respectively, the main plate between every two adjacent positioning parts forms an arch structure, and gaps for accommodating soft tissues are formed between the arch structures and the mandible stump boneor the transplantation bone. The jaw bone transplantation in-place guide plate ensures in-place guiding of the transplantation bone, also fully reserves muscles and other soft tissues carried by boneflaps, ensures functional recovery of a reconstruction operation and fullness of a face, and avoids a situation that the functional recovery is affected after the muscles and other soft tissues brought by the bone flaps are fully peeled off.

Description

technical field [0001] The invention relates to the technical field of oral and maxillofacial surgery medical instruments, in particular to a guide plate for implanting jaws in place. Background technique [0002] At present, digital surgical technology is developing rapidly and widely used in clinical surgery. Among them, the technologies that can accurately transform preoperative design into intraoperative operation include surgical navigation and guide plates. Surgical navigation requires a large and expensive navigator to register preoperative or intraoperative CT, MRI and other information with the patient entity during the operation, which is not only complicated to operate, but also has the possibility of navigation failure. Surgical guide plate technology has been used in orthopedics, plastic surgery, and maxillofacial surgery. Most of the data used come from CT or 3D scanning, which requires high equipment. The process of designing the guide plate is also very comp...
