Description

Improved manual oral expansion device

This creation is about an oral expansion tool, especially an improved manual oral expansion device that uses one-handed operation to achieve a fixed effect.

For patients with restricted oral opening angles, mouth opening exercises, cleaning of their oral cavity, or medical actions on their oral cavity are generally required with the assistance of an oral expansion device.

Conventional oral expansion devices generally use the upper and lower incisors and canine teeth of an oral cavity as resistance points. Therefore, in the process of opening an oral cavity, the incisors and canine teeth will bear considerable force. If it is not handled properly, its incisor or canine teeth may be damaged.

In addition, since the oral expansion device must be fixed after the oral cavity is opened to perform medical actions on the oral cavity, a fixing structure is provided on the oral expansion device to ensure that the patient's oral cavity is open. However, Since the fixed structure on the conventional oral expansion device must be fixed by additional manual operation, the patient cannot use only one hand to open the oral cavity, and even more so, the patient must use the assistance of others. The conventional oral expansion device is very inconvenient.
