Masticatory muscle training instrument

Abstract

The invention provides a masticatory muscle training instrument. The masticatory muscle training instrument comprises a pair of supporting pieces used for supporting an upper jawbone and a lower jawbone of a patient, a lead screw nut mechanism composed of a lead screw, a nut and a guiding device, an opening and closing mechanism with the top side and the bottom side connected with the supporting pieces respectively, and a power assembly connected with the lead screw and driving the lead screw to rotate alternately in the forward direction and the reverse direction; the rotation of the nut is limited by the guide device when the nut is screwed with the screw rod, and the nut moves along the advancing track limited by the guide device under the rotation of the screw rod; the opening and closing mechanism is movably connected with the nut, when the lead screw rotates in the forward direction or the reverse direction, the nut drives the opening and closing mechanism to enable the pair of supporting pieces to be expanded or folded, and the upper jawbone and the lower jawbone are opened and closed along with expansion or folding of the pair of supporting pieces; and the power assembly of the masticatory muscle training instrument drives the nut of the lead screw nut mechanism to enable the opening and closing mechanism to expand or close the pair of supporting pieces, and then the upper jawbone and the lower jawbone are opened and closed.

Description

Technical field [0001] The present invention relates to a rehabilitation medical instrument, and more particularly to a masticatory trainer. Background technique [0002] Nasopharyngeal carcinoma is one of the most common malignant tumors in my country, mainly in radiotherapy. However, the difficulty of Zhangkou is one of the common radiotherapy complications. The incidence can be as high as 58.5%, and the incidence of severe objections is 7.1%, especially when the DT40GY / 4W will begin, the cut teeth spacing is reduced, and the time of radiotherapy The extension, the increase in dose is aggravated, and the bilateral temporomandibular joint is multi-dose rays, leading to the joint activity and the mapping and maternal dysfunction of joint activity after chronic radioactive fibrosis. [0003] Quick muscle dysfunction includes the clinical symptoms of the Zhangkou, please refer to figure 1 As shown, a schematic diagram of anatomy is shown in the figure. It can be seen from the fig...

Problems solved by technology

For the radiation-induced masticatory muscle injury, it is difficult to contract due to the fibrosis of the lateral pterygoid muscle 103. Under the premise that the strength of the mouth closing muscle is greater than that of the mouth opening muscle, it is difficult for the patient to open his mouth.

[0004] At present, with the development of social economy and the improvement of people's living standards, people's pursuit of quality of life for rehabilitation has changed. At present, almost all tertiary hospitals have rehabilitation clinics and treatment rooms, and rehabilitation treatment is different from other departments. Rehabilitation medical equipment is used as a means to treat patients. At present, for the symptoms of limited mouth opening caused by masticatory muscle dysfunction, artificial stretching is currently used for rehabilitation treatment. There is no suitable rehabilitation medical equipment for patients. rehabilitation
