Description

Technical Field

[0001] The utility model relates to the field of oral care tools, in particular to an oral cavity stretcher. Background Art

[0002] When a dentist is performing oral care, the dentist needs to use a mouth opener to open the patient's mouth in order to see the patient's teeth better and more intuitively. The mouth openers currently used are mainly one-piece structures. When they are inserted into the mouth for fixation, the mouth needs to be opened, and the size of the opening must be larger than the size of the mouth opener, so that the mouth opener can be installed in the mouth. In this process, not only is the installation troublesome, but it also causes discomfort to the person who needs care. In addition, the elastic force of the mouth opener is uncontrollable and cannot be controlled within the tolerance range of the caregiver. Therefore, the high elastic force leads to a large opening angle, which causes pain to the caregiver with a small mouth shape. At present, mouth openers of different sizes cannot be fully adaptively adjusted according to the patient's mouth shape. For this reason, we propose an oral mouth opener. Utility Model Content
