An in-place guide plate applied to multi-segment fibula double stack reconstruction of mandible

Abstract

The invention relates to the technical field of medical instruments for oral and maxillofacial surgery, in particular to an in-place guide plate applied to multi-segment fibula double-stacked reconstruction of mandible, aiming at solving the problem that the height of the fibula of a single-layer segment after transplantation in the prior art may not be sufficient The technical point of helping the patient to restore the occlusal and masticatory function on the basis of restoring the appearance and appearance in the future is to include a first guide plate and a second guide plate, the first guide plate is located above the second guide plate, and the first guide plate is located above the second guide plate. The inner side of the plate and the second guide plate is provided with an arc-shaped groove for the fibula cut section to be placed after double stacking, the arc-shaped groove is closely fitted with the surface of the fibula, and the first guide plate and the second guide plate are symmetrically arranged There are retaining holes. The present invention completes the mandibular reconstruction operation through the digitally designed guide plate, which is more perfect in appearance and more ideal in function.

Description

technical field [0001] The invention relates to the technical field of oral and maxillofacial surgical medical instruments, in particular to an in-position guide plate applied to the reconstruction of the mandible by double stacking multi-segment fibula. Background technique [0002] At present, digital surgical technology has developed rapidly and is widely used in surgical clinics. 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 the operation, which is not only complicated to operate, but also has the possibility of navigation failure. Surgical guide technology has been applied in orthopaedics, plastic surgery, and maxillofacial surgery. Most of the data used is from CT or 3D scanning, which requires high equi...

AI Technical Summary

Problems solved by technology

[0005] Therefore, the technical problem to be solved by the present invention is to overcome the defect in the prior art that the thickness of the fibula of a single segment after transplantation may not be able to help the patient recover the function of occlusion and mastication on the basis of restoring the appearance, thereby providing a In-situ guide plate for multi-segment fibula double-stack reconstruction of mandible
