A tongue back elastic traction apparatus used for treating an obstructive sleep apnea-hyperpnoea syndrome (OSAHS) or a snoring disease comprises a tongue back connection mechanism (1), an elastic traction body (2) and a tooth-side fixer (3). The tongue back connection mechanism (1) is disposed on the tongue back. The tooth-side fixer (3) is fixed outside a tooth (5), or a tooth socket bone or an upper or lower jaw lip. One end of the elastic traction body (2) is connected to the tooth-side fixer (3), and the other end is connected to the tongue back connection mechanism (1), thereby forming an elastic traction apparatus using the tooth-side fixer (3) as a support point. The apparatus pulls a dropped tongue (4) up forwards, so as to prevent glossopharyngeal part airway stenosis and blockage and play a role in treating the snoring disease and the OSAHS. Because the elastic traction body applies an elastic traction force on the tongue back, the movement of the tongue tip is not affected when the tongue root is properly pulled up, thus a clear talking function and a proper deglutition function are maintained, the airway of the glossopharyngeal part is widened, and good comfort is provided. Also disclosed are a holding clamp (400), a mounting clamp (5), and a thread guiding apparatus (200) matching the tongue back elastic traction apparatus, and a method for implanting the tongue back elastic traction apparatus.
