Embodiment Construction

[0030] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

[0031] An in-place guide plate applied to the reconstruction of the mandible with multi-segment fibula double stacks, such as figure 1 and figure 2 As shown, it includes a first guide plate 11 and a second guide plate 12, the first guide plate 11 is located above the second guide plate 12, and the inner sides of the first guide plate 11 and the second guide plate 12 are provided with double fibula cutting sections. The arc-shaped groove 2 placed after being stacked closely fits with the surface of the fibula; in addition, the first guide plate 11 and the second guide plate 12 are symmetr...

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...
