Description
Technical Field
The utility model relates to the technical field of medical equipment, specifically indicate a temporomandibular joint and masseter muscle function rehabilitation training device.
Background
The main method for treating head and neck tumor adopts a treatment mode combining radiotherapy and chemotherapy, wherein radiotherapy rays are necessary factors for causing tissue damage in a radiation range, in the common complications of head and neck radiotherapy, radiation damage caused by rays to temporomandibular joint and masseter peripheral tissues causes adhesion and atrophy between temporomandibular joint and peripheral tissues, which causes complications such as limited joint movement, difficulty in opening mouth, pain, rigid masticatory muscles and the like, the method has the advantages that the method has serious influence on the physical function and the life quality of patients, a series of clinical symptoms of the patients with head and neck tumor, such as masticatory muscle tenderness, mouth opening pain, masticatory pain, abnormal jaw activity and the like, are generally called as masticatory muscle disorder, an effective method is found for solving the masticatory muscle disorder after the radiotherapy of the head and neck tumor, and the method has important effects on the treatment of the diseases of the patients and the guarantee of the later life quality; the main reasons for the difficulty in opening mouth caused by radiotherapy rays are as follows:
1. because the temporomandibular joint has tissue loss after radiotherapy, tissue adhesion and tissue atrophy are generated, the movement of the temporomandibular joint is limited;
2. when the temporomandibular joint is irradiated with high dose, phenomena such as reactive stiffness and exudation occur, which causes fibrosis and adhesion of soft tissues between temporomandibular joints, so that the movement of the joint is limited to cause difficulty in opening the mouth, wherein generally, the higher the irradiation dose is, the higher the incidence rate of the difficulty in opening the mouth is;
3. the occurrence of cellulitis and periodontitis on the head and face causes the phenomena of mouth opening difficulty, temporomandibular joint movement limitation and the like of nasopharyngeal carcinoma patients after radiotherapy.
At present, a plurality of treatment methods for difficult and limited opening after radiotherapy are available and mainly divided into two main categories: the patient actively exercises mouth and passively exercises mouth by using an instrument; the active mouth opening exercise of the patient mainly depends on the self-conscious discipline of the patient, when the temporomandibular joint region has pains of mouth opening, chewing and the like, the subjective activity of the patient is reduced, even the patient has a conflicting mood, the active mouth opening exercise is stopped, the effect of the mouth opening exercise cannot be continuously influenced, meanwhile, the consistency and the standard of each action cannot be ensured by the active mouth opening exercise, and the effect of the active mouth opening exercise is further reduced; the passive mouth opening training mainly enables a patient to passively open the mouth through an external opening support instrument, so that the mouth opening training effect is achieved; the normal opening degree is the distance between the incisor margins of upper and lower central incisors when a patient opens a mouth greatly, the opening degree of a normal person is about 3.7-4.5 cm, and the limitation of opening is indicated when the opening degree is lower than the value; at present, the domestic mouth opening training devices entering the market are not many, the mouth opening training devices of patients are still more than original wood wedge-shaped mouth opening devices, and other types of mouth opening training devices exist, such as: 1) the patent No. 201520261733.0 discloses a mouth opening training device of a pneumatic mouth opening device, which is an air bag type tooth socket, has a large volume, obvious mouth foreign body sensation and no accurate opening degree value, and can not be used once a pipeline leaks air; 2)3D prints individualized mouth gag mentions a 3D and prints individualized mouth gag in the application (the hauncher time, Li fei, wang forever just, 6 th 35 th volume of 2019 in 35 th 3 rd long period spring traditional chinese medicine university newspaper) of stretching out the mouth exercise after nasopharyngeal darcinoma patient's radiotherapy, the individualized denture base that the intraoral supporting part of this mouth gag was done according to patient's tooth model is divided into, in case the tooth drops appears, this mouth gag will be out of use, and do not have accurate opening degree numerical value, also do not have the fixed retaining device of a degree of stretching out. 3) At present, the mouth opening trainer on the market is generally divided into two types of adults and children, the plastic material is generally used, the overall design is horizontal design, the design of a handle holding part is large, and the mouth opening trainer is not suitable for being held by fingers for a long time in the process of resisting joint muscles to open the mouth passively.
