Lower jaw rehabilitation robot

Abstract

The invention relates to a lower jaw rehabilitation robot, which belongs to the field of medical apparatuses and is used for assisting the rehabilitation training of the lower jaw of a temporomandibular joint disturbance syndrome patient in the vertical, left and right directions. The lower jaw rehabilitation robot structurally and mainly consists of a servo motor, a speed reducer, a spline shaft, two pairs of bevel gears, a sleeve, a shifting fork, a shaft, a connecting rod, a shifting fork handle, a positioning pin, a rotating shaft, a cylindrical cam, a roller driven element, a lower jaw connecting element, a crankshaft, a connecting rod, a rocker, a tooth supporter, a lower jaw supporting element, a spring and a machine frame, wherein the spline shaft and a slippage bevel gear form sliding connection; the rotating shaft is fixedly connected with a first fixing bevel gear and the cylindrical cam; the lower jaw connecting element is fixedly connected with the roller driven element; the crankshaft is fixedly connected with a second fixing bevel gear; the connecting rod is connected with the crankshaft and the rocker through hinges; the tooth supporter is fixedly connected with the connecting rod; the spring is fixed between the lower jaw support element and the machine frame. The lower jaw rehabilitation robot has the advantages that the device is compact; the operation is convenient and safe; the cost is low; the lower jaw rehabilitation robot can be used for hospital or family rehabilitation training.

Description

technical field [0001] The invention belongs to the field of medical equipment, and relates to a mandibular rehabilitation robot especially suitable for patients with temporomandibular joint disorder syndrome. Background technique [0002] Temporomandibular joint disorder (TMD) is one of the common forms of mandibular movement disorder, with unknown etiology and multiple pathogenic factors. WHO listed it as the fourth oral epidemic disease affecting human health. The barrier-free movement of the mandible is the premise to ensure the smooth progress of human swallowing, singing, communication and snoring. The early recovery of mandibular diseases can greatly improve the quality of life of patients. Traditional treatment methods require the therapist to repeatedly train the patient's jaw according to the patient's condition, etiology and other factors. The rehabilitation effect and time depend more on the doctor's medical experience. It can be seen that the research on a safe...
