Description

Technical field [0001] The invention involves a medical auxiliary equipment, which specializes in a adjustable opening training device. Background technique [0002] With the acceleration of the rhythm of life, the incidence of oral temporal mandibular joint flocculation is higher. The main reason is that the joint disk is shifted, causing limited mouth to be restricted, and limited eloquence caused by some surgery, such as maxillofacial diseases.After inflammation, trauma, tumor, etc.) or some treatment (radiotherapy, surgery, etc.), the mandibular fracture, especially the fracture of the mandibular, after the mandibular surgery, especially the tumor of the mandibular and mandibular tumor, and some maxillofacial facilitiesLimited opening caused by the situation after the infection of the part of the part, which seriously affects the patient's pronunciation, language, eating and breathing function.For this reason, how to improve the effect of patients' opening training has been v...

Problems solved by technology

[0003]At present, the most effective way is to let the patients contact the mouth day by day to reduce or avoid the occurrence of complications. Passive mouth opening training can improve the degree of mouth opening and achieve The purpose of curing, however, this method often cannot be adhered to by patients, nor can it be objectively quantified, and the clinical effect is not good.

[0004]At present, foreign countries use simple mouth gags to put the thread into the upper and lower teeth of the mouth by rotating and gradually rotate the handle to increase the mouth opening.
