An implanted tongue pulling device including a pull plate, a pull line, a retractor and a method thereof are provided. The tongue pulling device is implanted in the mandible and tongue of a human body, respectively, for tightening the tongue dorsum and/or the tongue base for treating obstructive sleep apnea/hypopnea syndrome (OSAHS). At least three pull lines are used for positioning the pull plate, which is a flat object implanted beneath the tongue dorsum and/or the mucous membrane of the tongue base and includes through holes for the growth of tissues and pull line fixing mechanisms. The pull line includes a draw line and a sleeve. The retractor includes a casing, a control switch and a pull line fixing device mounted on the casing. A patient after surgery can adjust the tightening extent of the implanted tongue pulling device by pressing the skin outside the control switch, thereby preventing OSAHS. |

1. An implanted tongue pulling device, implanted into a mandible and a tongue body of a human being to tighten a tongue dorsum and/or a tongue base of the human being, comprising:
a pull plate, wherein the pull plate is a flat implant capable of being implanted under a mucous membrane layer of the tongue body, and includes one or more through holes facilitating growth of fibrous tissues and pull line fixing mechanisms; a pull line, wherein the pull line is a thread made of a material capable of being implanted into the human being; and a retractor, the retractor including a control switch capable of adjusting a tension of the pull line, a pull line fixing device capable of fixing the pull line, and a casing, wherein the control switch and the pull line fixing device are mounted in the casing, the control switch comprising a tightening switch, a loosening switch, and a ratchet, wherein: pressing the tightening switch causes the ratchet to rotate, thereby driving the pull line fixing device to tighten the pull line, pressing the loosening switch causes the ratchet to be released, thereby driving the pull line fixing device to loosen the pull line, and the pull line has a first end connected to the pull plate and a second end connected to the retractor. |
