Description

Mouth opening rehabilitation training device with vibration function

Technical Field

The invention relates to the technical field of medical instruments, in particular to a mouth opening rehabilitation training device with a vibration function.

Background

The patient probably arouses different degree's mouth openings after temporomandibular joint dysfunction, mandible condyloid process fracture, simple jaw ligation postoperative, temporomandibular joint operation, jaw face infection or the long-term radiotherapy of jaw face and restricts, and its oral cavity is opened and shut naturally and can not reach the state before the radiotherapy, and in order to resume patient's oral cavity and open the function, the patient need be with the help of the apparatus training of opening the mouth.

At present, two mouth opening trainers exist on the market, one is a soft plug, and the mouth opening trainer is used for mouth opening training by gradually plugging a conical soft plug into the mouth of a patient, but the mouth cavity is easily damaged by the mode. The other type is an air bag type mouth opening trainer, the current air bag type mouth opening trainer is generally characterized in that an air bag is arranged on the other side of two hinged mouth opening plates, the two mouth opening plates are driven to be opened and closed through inflation of the air bag, so that mouth opening training is carried out, but the general inflatable mouth opening trainer cannot determine the mouth opening range according to different patients, so that the joints of the patients are easily damaged, and the current inflatable mouth opening trainer cannot carry out mouth opening training according to the actual mouth opening condition of the patients. Because the joint moves forwards and downwards when the mouth is opened, the current mouth opening trainer can not induce the joint to move forwards, so that the training condition is poor, even the compression force between the articular disc and the condylar process can be increased, and finally the articular disc is absorbed, and the displacement and the deformation of the articular disc are increased.

It has been well documented that osteogenesis is promoted by appropriate micro-vibrations, so a vibrator has been introduced into our mouth-opening training device. When a patient is subjected to mouth opening training, the vibrator can be conducted to the temporomandibular joint through the mandible, so that micro-vibration at the joint is triggered, and the activity of chondrocytes and osteogenic differentiation are promoted. The other function of the vibrator can also avoid long-time joint pressure caused by mouth opening force in the mouth opening training process, and further avoid aggravation of bone absorption. When the mouth is opened normally, the joint moves forwards and downwards to drive the joint disc to move forwards, and when the temporomandibular joint disorder is caused, the joint can not move forwards due to the forward displacement and deformation of the joint disc, so that the mouth opening is influenced. Therefore, the better effect can be obtained by inducing normal lower-front jaw movement during mouth opening training.
