Description

Technical Field

[0001] The utility model relates to the technical field of medical nursing equipment, and more specifically to a pronunciation assisting device after total laryngeal surgery. Background Art

[0002] Total laryngectomy is a complex, radical surgical procedure for advanced laryngeal cancer. Because the larynx is closely connected to the respiratory tract and speech, and its anatomical structure is complex and delicate, patients may experience complications such as swallowing difficulties, dysphonia, and permanent tracheotomy after surgery. The permanent loss of language function severely limits patients' self-expression. Early on, they can only express themselves through non-verbal means such as writing, cards, gestures, nodding, shaking their heads, and lip reading. These expressions are often not understood, leading to severe negative emotions.

[0003] Voice rehabilitation is an important and necessary measure for speech recovery in patients undergoing total laryngectomy. It can improve patients' quality of life after surgery, alleviate negative emotions such as anxiety, depression, and aversion to communication, and contribute to improving their psychosocial adaptation and enabling their early reintegration into society. Currently, research on voice reconstruction methods in my country is still in its early stages. Reconstructed speech techniques such as electronic laryngeal speech, esophageal speech, and tracheoesophageal speech are slow, quiet, and unclear, and require patients to devote considerable time and effort to learning. These techniques are costly but ineffective, leading to patient disengagement and failure of voice reconstruction.
