Abstract

The invention provides an ear surgical device which comprises a holding part and an inserting part which are arranged in sequence, and a ventilation device movably arranged on the inserting part. In the inserting part, at least one part of a suction tube and at least one part of a pushing tube are contained in the outer sleeve, the pushing tube and the tubular body are sequentially arranged on different portions of the outer side wall of the suction tube in a sleeving mode in the extending direction of the outer sleeve, and the suction tube is communicated with the interior of the tubular body to form a suction channel. After the cutting piece acts on a target tissue and before the ventilation device is arranged at an incision, tympanic effusion which flows out can be discharged through the suction tube through the suction channel, so that the tympanic effusion which flows out is prevented from blocking the ventilation device, and good use safety is achieved.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to an ear surgery device. Background technique [0002] Many ear diseases, such as eustachian tube obstruction, catarrhal otitis media, secretory otitis media, barometric otitis media, and aviation otitis media, can cause tympanic effusions, which require timely drainage of tympanic effusions and targeted treatment. [0003] The Chinese patent with the publication number CN203898546U discloses a tympanic membrane incision and suction knife. After the tympanic membrane is incised, the ear needs to be withdrawn, and then the ventilation tube is placed at the tympanic membrane incision using a tube placement tool to connect the inside and outside of the tympanic membrane, thereby Realize the purpose of removing liquid and ventilating. However, the sequential use of the myringotomy suction knife and the catheterization tool prolongs the operation time and increases the pain...
