Fibula shaping board for use in mandibular reconstruction

Abstract

The invention discloses a fibula shaping board for use in mandibular reconstruction, which comprises an arc-shaped groove and a regulating screw, wherein the regulating screw passes through the front side face of the arc-shaped groove; the end, which extends out of the front side face of the arc-shaped groove, of the regulating screw is provided with a bracket; the arc-shaped groove has three osteotomy slots, and the sizes and positions of the three osteotomy slots are prescribed in the description; the middle slot is a chin angle osteotomy slot, and the size of a chin angle is 55 to 65 degrees; the slots at the two ends are mandible angle osteotomy slots, and the size of an mandible angle is 35 to 45 degrees and the distance between a front side face and a rear side face is 2.5 to 3.5 centimeters. Through morphological analysis on the mandible of common adults, an intrinsic common law is found, and the shaping parameters of the horizontal part of the mandible are determined; on the basis of the parameters, common fibula shaping plate is designed; and thus, the four-section shaping of a transplanted fibula in the reconstruction of the horizontal part of the mandible can be realized.

Description

Technical field [0001] The present invention involves oral and maxillofacial repair and reconstruction surgery. Background technique [0002] The vascular fibula tissue petals are gradually becoming the main skin flap of the mandibular reconstruction, and the accurate shaping of transplanted fibula has always been a tricky task facing the reconstruction of the surgeon.The traditional transplantation shaping is based on the pre -shaped mandible reconstruction board or based on the experience of the mandibular resection and preoperative imaging of the surgery. Therefore, the shaping is often not accurate and requires multiple grinding and adjustment.In recent years, with the development of computer -aided surgical technology, the application of commercialized surgical planning software (Surgicase, etc.) can achieve individualized surgical simulation and customized bone cutting template customization, which greatly improves the accuracy and effect of surgery. HoweverThe cost is expe...

AI Technical Summary

Problems solved by technology

Therefore, the clinical randomness and poor stability of traditional plastic surgery are large, and there is usually a large gap between the grafted bone segment and the reconstruction plate, which is unfavorable for fixation.

In recent years, the use of commercial computer-aided surgery software (Surgicase) to produce customized and individualized bone graft plastic templates has been reported, but the production cycle is long, the price is expensive, and the related technologies are monopolized by foreign companies, so it is not easy to promote
