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.

Abstract: A radial sealing assembly comprises an upper pressing plate, a protection sheet, a positioning plate, a funnel-shaped sealing ring, a lower pressing plate and a corrugated sealing ring. The upper pressing plate is provided with at least two convex connecting hooks for connection with the positioning plate; the lower pressing plate is provided with at least two connecting slots for connection with the positioning plate; the positioning plate is provided with at least two connecting slots for connection with the upper pressing plate and at least two convex connecting hooks for connection with the lower pressing plate; and both the upper pressing plate and the lower pressing plate are connected to the positioning plate by adopting concave-convex engagement structures.

Abstract: Disclosed is a trocar comprising a silencer. An end sealing assembly of a sheath of the trocar of the present application comprises an upper cover, a radial sealing assembly, a silencer and a lower cover; the silencer being an elastic body having one end installed on the radial sealing assembly and the other end installed on the lower cover; and the radial sealing assembly installed between the upper cover and the lower cover, Since the silencer holds up the radial sealing assembly, a gap between the upper cover and the radial sealing assembly is reduced, thereby avoiding an impact sound produced when a surgical instrument is withdrawn outwards, When the surgical instrument is advanced inwards, the impact sound produced when the surgical instrument is advanced inwards is avoided due to a buffer effect of the silencer.

Abstract: The present invention relates to an elastic tongue-dorsum refraction device for treating obstructive sleep apnea/hypopnea syndrome (OSAHS), clamping pliers, installation pliers, a line guide, and an implantation method. The elastic tongue-dorsum refraction device of the present invention includes a tongue dorsum connection mechanism, an elastic retractor and a tooth-side fastener. The tongue dorsum connection mechanism is disposed at the tongue dorsum portion, the tooth-side fastener is fixed to teeth or the alveolar bone or outside the maxilla and mandible lips, one end of the elastic retractor is connected to the tooth-side fastener, and the other end of the elastic retractor is connected to the tongue dorsum connection mechanism. In this way, an elastic retraction device using the tooth-side fastener as a fulcrum is formed.

Abstract: Disclosed are a low-resistance general sealing apparatus for a trocar and a trocar. A sealing ring (3) is compressed between an upper guiding mechanism (1) and a lower guiding mechanism (2). A smooth transition between the upper guiding mechanism (1) and the lower guiding mechanism (2) minimizes the contact area between the sealing ring (3) and a surgical instrument, which not only provides a guiding function when different forms of surgical instrument are inserted or removed, but also maximally transforms a “soft-hard” friction area between the sealing ring (3) and the surgical instrument into a “hard-hard” friction area between the plastics of upper and lower guiding mechanisms and an outer metal sheath of the surgical instrument, thereby greatly reducing the motion resistance, and meanwhile, having an excellent sealing effect. The sealing apparatus and the trocar are also applicable to instruments with diameters between 5 mm and 12 mm.

Abstract: A rotary structure having a large upper part, a small middle part and a large lower part is formed between guiding blocks (11) of a guiding mechanism (1). A positioning groove (10) is disposed at the wasp-waist of the guiding block (11). The bottom of a sealing ring (3) is embedded in the positioning groove (10) to surround the guiding block (11). When a surgical instrument is inserted, the sealing ring (3) confined within the positioning groove (10) extends out of the gap between the guiding blocks (11) to surround the instrument. The contact area between the sealing ring (3) and the instrument provides a guiding function to different forms of surgical instrument and transforms a “soft-hard” friction area between the sealing ring (3) and the instrument into a “hard-hard” friction area between a plastic guiding surface of the guiding blocks (11) and an outer metal sheath of the instrument.

Abstract: The present invention relates to a layered soft palate support and an implantation method for treating sleep apnea/hypopnea syndrome or snoring. The layered soft palate support is a flat implant made of a material capable of being implanted into a human body for a long term, and includes a hard palate connecting end and a support. The support is a layered structure formed by stacking two or more layers of supporting plates and capable of being inserted into a soft palate, and is removably or irremovably fixed to the hard palate connecting end. The hard palate connecting end has a connecting structure connected with a hard palate, and is fixed to the hard palate through the connecting structure. The support is implanted into a muscular layer of the soft palate, and is inserted into the soft palate by a length equal to ? to ? of its total length.
