In-position 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-position guide plate applied to multi-segment fibula double-stack reconstruction of the mandible, aims at solving the problem in the prior art that the height of a single-layer segment of fibulas after transplantation cannot help a patient in rehabilitation of the occlusalchewing function on the basis of rehabilitation of the appearance of the patient subsequently. The in-position guide plate applied to multi-segment fibula double-stack reconstruction of the mandibleis technically characterized by comprising a first guide plate and a second guide plate, wherein the first guide plate is located above the second guide plate, the inner side of the first guide plateand the inner side of the second guide plate are provided with arc-shaped grooves for cut fibula segments to be placed after double stacking, the arc-shaped grooves are closely fit with the surface ofthe fibulas, and the first guide plate and the second guide plate are symmetrically provided with retention holes. The mandibular reconstruction operation is completed through the digitally designedguide plate, and the guide plate is more perfect in appearance and can functionally achieve a desired effect.

Description

technical field [0001] The invention relates to the technical field of oral and maxillofacial surgery medical instruments, in particular to an in-position guide plate applied to multi-segment fibula double-stack reconstruction of the mandible. 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...

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
