Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of medical devices, and particularly relates to an oral puncture model. BACKGROUND

[0002] Oral medicine is a highly operational discipline, and its clinical teaching is quite difficult. Oral and maxillofacial local anesthesia is an important part of oral teaching, and perfect oral and maxillofacial local anesthesia is the premise and basis for completing tooth extraction, pulp extraction, tooth preparation, periodontal surgery and many other daily outpatient treatments. Oral and maxillofacial local anesthesia is a basic skill in oral clinical practice. In the past, students could only observe and learn from teachers in the clinical operation site, and could not directly operate. In recent years, simulation models have emerged to effectively assist students in practicing anesthesia operations. The current oral anesthesia model mainly includes a simulation model of a certain proportion or a jawbone model with a sensing component. Since the above-mentioned oral anesthesia model has been put into use, it has met the current needs of students for clinical experiments, but its structure has obvious defects: first, the simulation model on the market lacks test criteria, and students cannot directly observe the path and depth of the anesthesia needle tip. Second, the sensing components used in the current jawbone model are mostly pressure-sensitive disc sensors, which have a short service life. Especially in the frequent operation of anesthesia injectors, the sensing components often need to be replaced after a short period of use, resulting in increased maintenance complexity and use cost. It is a technical problem for those skilled in the art to develop a practical oral anesthesia model with a reasonable structure to overcome the inconvenience of the current model structure and better meet the actual needs of users.
