Abstract

The invention relates to a medical device, in particular to an external auditory canal dilator. An external auditory canal dilator, comprising a cylindrical seat post, three gaps are uniformly arranged on the lower end of the seat post, a fixing post is arranged near the bottom end of the seat post in the notch, an expansion piece is arranged in the gap, and an expansion sleeve is provided on the upper end of the seat post , the expansion sheet is a long strip-shaped structure that is curved toward the seat post and is symmetrical along its vertical center line. Compared with the prior art, the present invention has the following advantages: reducing the incidence of inflammation and facilitating treatment in the auditory canal; the spiral downward pressure can ensure that the downward pressure is soft and stable, easy to locate, reduces the pain of patients and reduces the damage to the narrow and closed external auditory canal .

Description

technical field [0001] The invention relates to a medical device, in particular to an external auditory canal dilator. Background technique [0002] The external auditory canal is an "S"-shaped curved duct from the outer ear door to the tympanic membrane, with a length of 2.0 to 2.5 cm. From the outside to the inside, the external auditory canal first moves forward and upward, then turns backward, and finally forward and downward. The surface of the external auditory canal is covered with a thin layer of skin, which contains rich sensory nerve endings, hair follicles, sebaceous glands, and cerumen glands. Ear canal examination and surgery are an important part of ENT treatment, and external ear examination and surgical incision are inseparable from the automatic spreader. The conventional automatic spreader of the automatic spreader that generally works in the hospital at present all is two blades with teeth, and the incision is opened by the principle of leverage. It has...
