Filling air bag for otological operation and manufacturing method thereof

Abstract

The invention relates to a filling air bag for an otological operation and a manufacturing method thereof. The air bag is characterized by comprising an air bag main body, an inflation pipe communicated with one side of the air bag main body and an indication ball bag and an inflation valve which are connected with the inflation pipe. The appearance of the air bag main body is designed to be in the shape of a broad bean meshed with a mastoid operation cavity, an arc hook portion integrated with the air bag main body is arranged on the tail portion of the air bag main body, and an inflation pipe connector integrated with the air bag main body is manufactured on one side of the air bag main body to facilitate inflation pipe connection. The air bag has the advantage that the shape of the air bag is designed according to the mastoid operation cavity to enable the air bag and the mastoid operation cavity to be well meshed. The air bag is adjustable and even in pressure, and a good supporting effect can be achieved. The contact area of the air bag and the mastoid operation cavity can be reduced as much as possible in the insertion and taking process to avoid secondary trauma. The connection portion of the inflation pipe connector is smooth and free of corner angles, and damage to a patient is reduced. The inflation air bag is simple in operation and capable of shortening operation time and reducing complication to further reduce pains of patients.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a filling air bag for ear surgery and a manufacturing method thereof. Background technique [0002] In clinical otological surgery, in order to prevent damage to the mastoid cavity and the external auditory canal after surgery, it is often necessary to pack the mastoid cavity and the external auditory canal. Currently, the most commonly used packing materials are iodoform gauze and medical absorbent gelatin sponge. Due to the special anatomy and irregular structure of the ear, the stuffing material after surgery should have plasticity; affected by individual differences, the size of the mastoid cavity varies greatly; affected by the differences in blood coagulation function and local lesions The pressure required for postoperative packing is also different, so the above packing materials cannot meet the requirements that the shape is consistent with the opera...
