AI Technical Summary

Technical Problem

Existing mandibular rehabilitation trainers cannot simultaneously achieve mouth opening, mandibular protrusion, and mandibular lateral movement, thus failing to meet the multifunctional rehabilitation training needs of patients after oral and maxillofacial surgery or radiotherapy, resulting in poor rehabilitation training effects.

Method used

Design a mandibular rehabilitation exercise trainer, comprising a first training component for mouth opening training, a second training component for mandibular protrusion training, and a third training component for mandibular lateral movement training. The maxillary and mandibular positioning plates are driven to translate by a handheld motion actuator, and combined with an electric or manual actuator, multifunctional rehabilitation training is achieved.

Benefits of technology

This device enables simultaneous mouth opening, mandibular protrusion, and mandibular lateral movement on a single rehabilitation trainer. It helps patients perform rehabilitation training correctly, ensuring that they maintain the maximum range of motion for a sufficient amount of time. Sensors monitor the range of motion in real time, improving rehabilitation effectiveness, shortening rehabilitation time, reducing the impact of functional impairment, and improving quality of life.

Abstract

The application discloses a mandibular rehabilitation exercise trainer and a rehabilitation training method thereof. The mandibular rehabilitation exercise trainer comprises a first training assembly for mouth opening training, a second training assembly for mandibular protrusion training and a third training assembly for mandibular lateral movement training; the first training assembly, the second training assembly and the third training assembly each comprise a maxillary positioning plate and a mandibular positioning plate, and the maxillary positioning plate and the mandibular positioning plate each comprise a tooth occlusion limiting groove in a U shape; the mandibular rehabilitation exercise trainer further comprises a handheld action executing mechanism for driving the maxillary positioning plate and the mandibular positioning plate to move relatively in translation, and the handheld action executing mechanism drives any one of the maxillary positioning plate or the mandibular positioning plate to move in translation; the handheld action executing mechanism is provided with a dynamic side mounting position and a static side mounting position, and the dynamic side mounting position can be switched between being adjacent to and being away from the static side mounting position. The mandibular rehabilitation exercise trainer realizes three functions of mouth opening, mandibular protrusion and mandibular lateral movement.
