Abstract

The larynx speech organ reconstructing device includes cutting and stitching trigger, cutting and stitching trigger base board, push rod barrel, screw push rod, cutting and stitching base board and cutting and stitching unit. The cutting and stitching trigger base board and the push rod barrel are connected to form one pistol-shaped structure, the screw push rod is set inside the push rod barrel and has top end connected to the cutting and stitching unit. The cutting and stitching base board is mounted on cutting and stitching unit head frame and in the position corresponding to the cutting and stitching unit. The cutting and stitching trigger is mounted in front of the cutting and stitching trigger base and has one end hinged to the screw push rod. Compared with available technology, the present invention has simple and short time operation and greatly raised operation accuracy.

Description

Technical field: [0001] The invention relates to a medical device, in particular to a laryngeal pronunciation reconstructor for laryngeal cancer patients to perform pronunciation reconstruction with functional tracheoesophageal fistula after total laryngectomy. Background technique: [0002] Total laryngectomy is suitable for advanced laryngeal cancer. Since aphasia after surgery brings great inconvenience to patients, how to better restore language function, that is, the establishment of pronunciation reconstructor, is the focus of current research in this field. There are three main methods for pronunciation reconstruction after total laryngectomy: [0003] (1) The pronunciation of the pharynx and trachea. A small number of patients with this method can speak naturally, but most require training. The success rate of pronunciation is about 30%-40% to 97%, and the volume is generally low; [0004] (2) Wearing an artificial throat. There are many kinds of artificial laryn...
