Abstract

The invention discloses a dilator for otologic surgery, and the dilator comprises a dilation hopper, a pressurizing pipe, a medicament barrel, a push rod, a first supporting column, a battery shell and a second supporting column; a mounting part is mounted on the inner wall of the dilation hopper, the pressurizing pipe is mounted at the output end of the mounting part, and a medicament conveying pipe is mounted at the other end of the mounting part; a butt joint opening is formed in one end of the medicine conveying pipe, an embedding head is embedded in the inner side of the butt joint opening, a medicine barrel is installed at one end of the embedding head, a guide cover is installed at one end of the medicine barrel through threads, a push rod is installed on the inner side of the guide cover in a penetrating mode, and a first supporting column is installed on one side of the expansion hopper; a shell is mounted on the inner side of the bottom end of the first supporting column, and a battery shell is mounted at the bottom of the shell. Medicine is pressurized through the pressurizing pipe, so that the medicine is conveyed into the medicine spraying head, the medicine is converted into mist through the medicine spraying head, the medicine is sprayed into the ears of a patient, and a user can apply the medicine conveniently during an operation.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to an expansion device for ear surgery. Background technique [0002] Otological surgery is usually dilation of the external auditory canal, which is used to expand the narrow auditory canal so that patients can hear clearly. The same side is dysplastic, so when the cartilage is removed, only part of the protrusion is removed, and the subcutaneous part of the face is kept to avoid aggravating the facial deformity. For the appendage in front of the tragus that fuses with the tragus, the ear can be reconstructed after tragus resection, and it needs to be expanded with equipment during the operation to facilitate the operation. [0003] The defective that existing otological surgery expansion exists is: [0004] 1. The comparative document CN 211094370 U discloses a dilator for plastic surgery of the nose, "including a fixed buckle, a connecting rod, a left handle, an adj...
