Background

The vocal fold of human is based on the acoustic ligament between the posterior anterior horn of the thyroid cartilage and the vocal cord process of the arytenoid cartilage, and is formed by the vocal cord muscles and the mucous membrane on the surface of the vocal cord muscles. The vocal cords are the main structure of human vocalization, from very slight hoarseness to complete aphonia, and are mostly caused by the pathological changes of the vocal cords or the obstruction of the normal movement of the vocal cords due to other causes. Uneven vocal cord tension, incomplete glottis closure, etc. can all affect vocal cord vibration and sound. Therefore, the vocal cords have a vital role for the human body, and diseases in the vocal cords are receiving more and more attention.

In conventional vocal cord lesion excision surgery, if a lesion grows at the junction of the anterior portions of the bilateral vocal cords, the lesion at the anterior junction needs to be excised. After excision of the lesion, the anterior mucosa of the two vocal cords is damaged simultaneously, and the wound can heal slowly with time, but the healing size of the wound cannot be controlled. If the wound healing surface is too large, the vocal cords on two sides are adhered, so that the patient has hoarseness or difficulty in speaking, and serious sequelae are left after the operation.

In the existing teaching methods, a method capable of solving the problem of bilateral vocal cords adhesion after a patient has a vocal cord lesion is not provided.

Therefore, an anti-adhesion laryngeal dilator combination device is urgently needed to be found, and the dilator can effectively prevent the vocal cords on two sides from being adhered after the operation, so that the influence of the operation on the sounding of a patient is avoided; the dilator can also play a guiding role in teaching.
