Description

Temporomandibular drafting device

Technical Field

The invention relates to the technical field of medical instruments, in particular to a temporomandibular joint rehabilitation training device.

Background

The temporomandibular joint is also called temporomandibular joint or mandibular joint, consists of a mandibular head, a temporomandibular fossa and joint nodules, is the only left and right bilateral linkage joint of the maxillofacial region, has certain stability and multidirectional mobility, and governs various important activities such as chewing, swallowing, speaking, expression and the like.

At present, common temporomandibular joint diseases comprise temporomandibular joint disorder syndrome, or chewing muscle group dysfunction, joint structural disorder and joint organic change caused by external serious trauma, radioactive therapy and the like, so that patients cannot chew, swallow, speak and the like normally.

The existing temporomandibular joint rehabilitation methods mainly include traditional rehabilitation methods such as cork method, wet towel method, or self-exercise without aid of an apparatus, and apparatus-assisted rehabilitation methods. Such methods are tedious and often difficult to persist. The instrument assisted rehabilitation method is to perform rehabilitation training of temporomandibular joints by means of medical instruments. The temporomandibular joint rehabilitation training device on the market at present is often simple in function, can only realize static traction or has a large integral volume and unadjustable traction force, and the temporomandibular joint rehabilitation device with complex function is usually complex in structure and large in head bearing.

In summary, the existing temporomandibular joint rehabilitation training device is still inconvenient and deficient in use function and structure, and the patient experience is poor, so further improvement is urgently needed.

Disclosure of Invention

In view of the above-mentioned shortcomings of the prior art, the present invention aims to provide a temporomandibular joint rehabilitation training device with adjustable stretching force, simple structure, small mouth weight, low cost and high user experience.

The application provides a temporomandibular stretching device, which comprises an upper biting plate, a lower biting plate and a pneumatic device, wherein the pneumatic device is connected between the upper biting plate and the lower biting plate.
