Abstract

The invention belongs to the technical field of medical apparatuses and instruments and particularly relates to a mouth opening trainer. The mouth opening trainer comprises a base, a tooth opening assembly, a propulsion assembly and a cheek supporting assembly. The rear side of the base is provided with a left rail and a right rail; the tooth opening assembly comprises an upper tooth supporting plate, a lower tooth supporting plate, a left rack and a right rack, wherein the left rack and the right rack are arranged in the left rail and the right rail respectively, the upper tooth supporting plate is connected to the right rack, and the lower tooth supporting plate is connected to the left rack; the propulsion assembly includes a screw rod, a handle sleeve with an inner thread in the middleand force transmission rods, the front end of the screw rod penetrates through the base from the portion between the left and right rails, the rear end of the screw rod is in threaded connection withthe interior of the handle sleeve and penetrates through the rear end of the handle sleeve, the screw rod is provided with a gear which is matched with the left rack and the right rack, the handle sleeve is hinged to the force transmission rods, and the other ends of the force transmission rods are hinged to the cheek supporting assembly. The cheek supporting assembly includes a left cheek supporter and a right cheek supporter. Passive training of the cheek part and the upper and lower alveoli is achieved simultaneously through simple operation, the operation strength is controlled in a simple manner, and the mouth opening trainer is safe, convenient and effective.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to an opening trainer. Background technique [0002] Nasopharyngeal carcinoma is one of the malignant tumors with a high incidence in my country. The most effective and preferred treatment method is radiotherapy. The complications of radiotherapy will greatly affect the quality of life of patients with the prolongation of patient survival. Difficulty opening the mouth is one of the most common sequelae after radiation therapy. Initially, it manifests as pain when opening the mouth and tightness of the temporomandibular joint. Even trismus, difficulty in eating, causing malnutrition and even dyscrasia in patients. Studies have shown that mouth opening exercise is an important method to prevent temporomandibular joint fibrosis after radiotherapy. The temporomandibular joint and masticatory muscles can be activated through passive mouth opening and supporting actions to preven...
