Embodiment Construction

[0022] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0023] As shown in the figure, an ear canal restoration device is composed of a support body 1 and a bolt 2, wherein the support body 1 is made of flexible material medical silicone, and can also be made of other flexible polymer materials, such as polyurethane or polytetrafluoroethylene. vinyl. Inside the supporting body 1 there is a hole 3 along the axial direction, and the bolt 2 is screwed in the hole 3 . In order to meet the physiological requirements of the ear canal, the support body 1 can be made into a trapezoidal cylindrical structure similar to the shape of the ear canal. The diameter of the tail of the supporting body 1 is larger than the diameter of the ear canal, and the purpose is to prevent the supporting body 1 from going deep into the ear canal and hurting the tympanic membrane during use. The diameter of the bolt 2 is larger than the diameter of ...

Description

technical field [0001] The invention relates to the field of medical auxiliary equipment, in particular to an ear canal restorer. Background technique [0002] At present, in the treatment of external auditory canal fractures, the usual practice is to let the fracture site grow naturally, and after the fracture site heals, the ear bone protruding in the ear canal is removed through surgery. This method not only causes pain to the patient, but also increases Because of the risk of surgery, it is of great value to develop an orthodontist that can reset the fracture site without surgery. [0003] For the problem of dealing with the stenosis and atresia of the external auditory canal caused by various reasons, a kind of ear canal support is disclosed in the publication number CN1413741 patent document. A trapezoidal cylindrical tubular structure similar in shape to the ear canal is formed on the wire mesh. When in use, the bracket is compressed and deformed in 15-degree cold w...
