Inferior alveolar nerve protection guide plate based on mandible cystic lesion scaling

Abstract

The invention relates to the field of medical instruments for maxillofacial orthopedics, in particular to an inferior alveolar nerve protection guide plate based on mandible cystic lesion scaling. The inferior alveolar nerve protection guide plate comprises a guide plate body. The guide plate body is provided with a guide plate inner side face and a guide plate outer side face, and is further provided with a guide plate front edge, a guide plate rear edge, a guide plate upper edge and a retainer. The guide plate front edge and the guide plate rear edge serve as the left end and the right end of the guide plate body respectively, the end of the guide plate front edge is provided with a cystic lesion anterior boundary indication edge, and the end of the guide plate rear edge is provided with a cystic lesion posterior boundary indication edge. The guide plate upper edge is located at the upper end of the guide plate body, the end of the guide plate upper edge is provided with a guide plate upper edge line, and the form of the guide plate upper edge line is completely fit with that of a cystic lesion lower edge needed for preoperative simulation. The retainer is located at the bottom end of the guide plate inner side face and is concave, and the form of the retainer is completely fit with that of a mandibular angle needed for preoperative simulation. Through the protection guide plate, important anatomical structures such as the inferior alveolar nerve are positioned and protected, and meanwhile intra-operative guidance is provided; the guide plate is easy and convenient to operate and low in price.

Description

Technical field [0001] The invention relates to the field of maxillofacial plastic surgery medical instruments, in particular to a protective guide plate for inferior alveolar nerve based on curettage of mandibular cystic lesions. Background technique [0002] The inferior alveolar nerve is a branch of the mandibular nerve. After branching from the mandibular nerve, it runs through the mandibular foramen in the mandibular canal in the mandible, which gathers the gingival sensory nerve from the lower alveolar and most dental nerves. Finally it spreads out in the mental foramen as the mental nerve. The inferior alveolar nerve of patients with mandibular cystic disease is often involved. After injury, it is easy to cause numbness and discomfort of the affected lower lip and mandibular teeth. For such patients, cystic lesion curettage is mostly used. The course and morphology of the inferior alveolar nerve varies from patient to patient due to factors such as their own anatomical va...

AI Technical Summary

Problems solved by technology

The course and shape of the inferior alveolar nerve vary from patient to patient due to factors such as anatomical variations and cystic lesions. Doctors often cause nerve damage due to the inability to grasp the precise location of the inferior alveolar nerve during surgery.

[0003] With the rapid development of digital surgical technology and its wide application in surgical treatment, surgical guide plate technology has been applied in oral and maxillofacial surgery. There are relatively few studies on the positioning and protection of important anatomical structures such as the trough nerve
