Mouth opening exercise device for individual radiotherapy with controllable opening range

Abstract

The invention relates to a mouth opening exercise device for individual radiotherapy with a controllable opening range, and belongs to the technical field of medical instruments. The mouth opening exercise device comprises a hard palate plate, a tongue pressing plate, a connecting mechanism and an opening range adjusting device, wherein the hard palate plate is movably connected with the tongue pressing plate through a hinge, and the hinge is provided with a torsion spring for enabling the mouth opening exercise device to be opened; the opening range adjusting device is arranged at the front end between the hard palate plate and the tongue pressing plate and can be used for adjusting the opening range of the mouth opening exercise device outside an oral cavity. The mouth opening exercise device for the individual radiotherapy with the controllable opening range, disclosed by the invention, has the advantages that the adjustment on the opening range can be effectively realized, the needed opening range and the needed opening strength can be directly adjusted outside the oral cavity, the purpose of exercising can be achieved, the operation is flexible, and the use is simple and sanitary.

Description

technical field [0001] The invention relates to a mouth opening exercise device for radiotherapy, in particular to a mouth opening exercise device for radiotherapy. Background technique [0002] Nasopharyngeal carcinoma is a common malignant tumor in my country. With the comprehensive treatment of nasopharyngeal carcinoma, especially the advancement of radiotherapy, the survival rate has increased. Therefore, the long-term survival quality is the focus of concern at present, and difficulty in opening the mouth is the radical cure for nasopharyngeal carcinoma. One of the sequelae of radiotherapy, its incidence rate is about 58%. Advanced radiotherapy techniques such as conformal intensity-modulated radiotherapy cannot completely avoid its occurrence, and difficulty in opening the mouth is still a common sequelae. The mechanism of mouth opening difficulty is that the temporomandibular joint and masticatory muscles are damaged by radiation, degeneration and gradual fibrosis oc...

Problems solved by technology

CN103099721A Oral rehabilitation training device includes a trapezoidal training body and a square training body. The height of the square training body is increased by rotating the threaded socket of the square training body. The disadvantage is that the height of the training body needs to be adjusted in advance and then put into the oral cavity for training. The operation is troublesome and unhygienic

The utility model patent CN203555928U utilizes the ventilation tube to inflate the upper oral cavity airbag and the lower oral cavity airbag to change the state of mouth opening, but the hardness of the inflated airbag is not enough to achieve the purpose of exercise
