Problems solved by technology

[0004] Therefore, when the present invention fixes the osteotomy guide plate, it is necessary to use retaining nails to fix the osteotomy guide plate on the face, which will cause further damage to the patient’s face and affect the recovery of the patient’s postoperative face, thereby providing a mandibular osteotomy guide plate. bone guide

Embodiment

[0037] refer to figure 1 and figure 2 As shown, the present invention provides a mandibular osteotomy guide, which aims to apply digital design and 3D printing technology to orthognathic surgery. The mandibular osteotomy guide is made by 3D printing technology to simulate the post-operative occlusal state. When sagittal splitting of the mandible is required in orthognathic surgery, when the osteotomy guide is not used, the doctor needs to rely on clinical experience at this time. The mandible is split sagittal. During the splitting process, it is easy to cause uneven force because the direction of force is not fixed each time, resulting in additional fractures of the patient, which is not conducive to postoperative recovery. The application of the osteotomy guide in this embodiment can Let the doctor always perform sagittal split in the osteotomy groove, the path is fixed, and it is easier to grasp the strength, thereby reducing the risk of additional fractures.

Abstract

The invention relates to a lower jawbone osteotomy guide plate which comprises a guide plate body, the guide plate body comprises a guide plate base body part tightly attached to a lower jawbone and an occlusion part, the guide plate base body part extends from the inner face of the lower jawbone to the outer face of the lower jawbone, and an arc-shaped face tightly attached to the surface of the lower jawbone is formed on the inner side of the guide plate base body part. Osteotomy grooves are formed in the inner face of the lower jawbone, the outer face of the lower jawbone and the portion, at the junction of the inner face of the lower jawbone and the outer face of the lower jawbone, of the guide plate base body, the osteotomy groove in the inner face of the lower jawbone is obliquely formed, and the osteotomy groove is consistent with the position of an osteotomy line and the osteotomy amount; according to the postoperative functional recovery guide plate, the guide plate base body part can be fixed without using additional fixing nails, so that further damage to the face of the human body caused by the fixing nails is avoided, and the postoperative functional recovery effect of a patient is effectively improved.

Description

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