Benefits of technology
The invention provides a novel way to retract the tongue base while avoiding damage to the tongue soft tissues. It allows for adjustable pulling force after surgery and features a double-button type retractor that can be conveniently adjusted after surgery. The technical effect of this invention is an optimal therapeutic effect achieved through precise control of pulling distance and force.
Problems solved by technology
Moderate and serious OSAHS cases are often accompanied by multiple plane obstruction, and it is difficult to achieve the desired efficacy by simply adopting a UPPP surgery or other surgical methods aimed at the palatopharyngeal plane.

embodiment 1
A Tongue Pulling Device of the Present Invention
[0286]Referring to FIG. 1, this embodiment shows the basic structure of a tongue pulling device of the present invention.
[0287]The tongue pulling device of the present invention includes a pull plate (1), a pull line (2), and a retractor (3). The pull plate (1) is a flat implant capable of being implanted under the mucous membrane layer of the tongue base portion and / or the tongue dorsum portion of a human body, and includes through holes (101) allowing growth and penetration of human tissues and pull line fixing mechanisms (102). The pull line (2) is a thread made of a material capable of being implanted into the human body for a long term. The retractor (3) includes a control switch (301) capable of adjusting a tension of the pull line (2), a pull line fixing mechanism (302), and a casing (304). The pull line (2) has one end connected to the pull plate (1) and the other end connected to the retractor (3).
[0288]In this embodiment, the...
embodiment 2
A Tongue Pulling Device Having a Rectangular Pull Plate of the Present Invention
[0296]Referring to FIG. 2, in this embodiment, the pull plate (1) adopts a rectangular spatial curved plate structure.
[0297]Main dimensions of the rectangular pull plate (1) include:
[0298]a radian R of the curved surface being 10 mm to 120 mm, and preferably 20 mm to 50 mm;
[0299]a width W of the curved surface being 10 mm to 50 mm, and preferably 15 mm to 30 mm;
[0300]a height H of the curved surface being 10 mm to 50 mm, and preferably 20 mm to 35 mm;
[0301]a thickness T of the plate being 0.1 mm to 1 mm, and preferably 0.4 mm to 0.8 mm; and
[0302]a diameter φ of the through hole (101) being 0.1 mm to 4 mm, and preferably 0.5 mm to 2 mm.
[0303]Typical dimensions (width×height) include: 15 mm×20 mm, 18 mm×25 mm, 20 mm×30 mm, 25 mm×35 mm, 30 mm×35 mm, 35 mm×35 mm, 35 mm×40 mm, 40 mm×40 mm and the like.
[0304]The pull plate (1) is made of a material selected from a group consisting of, but not limited to: medic...
embodiment 3
A Tongue Pulling Device Using Two Pull Plates of the Present Invention
[0307]Referring to FIG. 3, the basic principle of this embodiment is similar to that of Embodiment 2 shown in FIG. 2. The difference lies in that: two the pull plates (1) are used, which are mounted on left and right sides of the tongue base portion and / or the tongue dorsum portion, and disposed into the muscular layer under the mucous membrane layer, where each of the pull plates (1) is fixed by using four pull lines (2), and therefore, a total of eight pull lines are used.

Abstract
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.
Description
BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a tongue pulling device including a pull plate, a pull line, and a retractor, which are implanted into the mandible and the tongue body of a human body, and more particularly to a tongue pulling device including a pull plate, a pull line, and a retractor implanted in the tongue base and / or the tongue dorsum for treating adult obstructive sleep apnea / hypopnea syndrome (OSAHS) and an implantation method.[0003]2. Related Art[0004]Adult OSAHS is a sleep breathing disorder with clinical features of snoring and apnea caused by upper airway collapse and obstruction during sleep. The major hazard of OSAHS is that frequent sleep apnea and hypopnea result in lowered oxygen saturation levels during sleep for a long term, causing a series of pathologic changes in the human body, thus becoming the cause of various systemic diseases (such as diabetes, hypertension, coronary heart disease, and cerebrov...
