Problems solved by technology

Most of the existing mouth expanders are disposable medical devices with fixed size, which cannot be adjusted independently according to the size of the patient's mouth. During use, there will often be a problem that the mouth expander does not match the size of the patient's mouth. The work is inconvenient, and the hospital needs to stock a variety of mouth flares of different sizes, which takes up a lot of space

Embodiment Construction

[0020] refer to Figure 1 to Figure 5 , a medical adjustable oral dilator of the present invention, comprising an adjusting rod 1, a limiting sleeve 2, an elastic sheet 3 and an oral support sheet 4, the adjusting rod 1 is threaded and fixed in the threaded hole in the center of the limiting sleeve 2, the The upper end of the limiting sleeve 2 is provided with a narrowing tube 22 whose diameter gradually decreases from top to bottom. The top ends of the elastic pieces 3 all protrude from the necking tube 22 and are gradually pressed by the necking tube 22 as the adjustment rod 1 moves down along the limit sleeve 2 to approach each other. The oral cavity support piece 4 is detachably fixed At the top of the elastic sheet 3.

[0021] The outer wall of the upper end of the adjusting rod 1 is provided with an external thread 11, the limit sleeve 2 includes a straight tube 21 and a flared tube 22, and the inner wall of the straight tube 21 is provided with an internal thread that ...

Abstract

The invention discloses a medical adjustable oral dilator. The dilator comprises an adjusting rod, a limiting sleeve, elastic sheets and an oral cavity supporting sheet, the adjusting rod is fixed ina threaded hole in the center of the limiting sleeve in a threaded modem, a necking pipe of which the caliber is gradually reduced from top to bottom is arranged at the upper end of the limiting sleeve, the two elastic sheets are symmetrically arranged at the top end of the adjusting rod, and the distance between the elastic sheets is gradually reduced from top to bottom, the top ends of the two elastic sheets both extend out of the necking pipe and are gradually pressed by the necking pipe to get close to each other along with downward movement of the adjusting rod along the limiting sleeve,and the oral cavity supporting sheet is detachably fixed to the top ends of the elastic sheets. Adjustable dilation of the oral cavity of a patient can be achieved, the overall structure is simple, use is convenient, and applicability is high.

Description

【Technical field】 [0001] The invention relates to the technical field of dilators, in particular to the technical field of a medical adjustable oral dilator. 【Background technique】 [0002] At present, when performing an oral examination or operation on a patient, the patient needs to open his mouth to the maximum extent for a long time. Due to the long-term active mouth opening of the patient, it is easy to cause oral muscle fatigue, so the hospital usually needs to use a mouth expander to mechanically expand the patient's oral cavity. Most of the existing mouth expanders are disposable medical devices with fixed size, which cannot be adjusted independently according to the size of the patient's mouth. During use, there will often be a problem that the mouth expander does not match the size of the patient's mouth. The work is inconvenient, and the hospital needs to stock multiple mouth flares of different sizes, which takes up a lot of space. 【Content of invention】 [0...
