Abstract

The invention discloses an auditory tube aspirator. The auditory tube aspirator comprises a connecting tube, an aspirating opening is formed in the front end of the connecting tube and fixedly connected with and communicated with the connecting tube, and a negative-pressure device is arranged at the rear end of the connecting tube. Through the connecting tube, the auditory tube aspirator penetrates through the auditory tube of a human body, then the aspirating opening abuts against the root of an ear, then the tail end of the connecting tube is guided out from the nasal cavity and then connected with the negative pressure device, in this way, in an ear operation, smoke can be taken away through the auditory tube through aspirating, and the smoke generated in the operation of the otology iseffectively removed.
