Description

Tympanic membrane ventilation tube plug assembly

[0001] The present invention relates to a tympanic membrane ventilation tube plug assembly. More specifically, the present invention relates to a tympanic membrane ventilation tube plug assembly that can prevent the tympanic membrane ventilation tube and the tympanic membrane plug inserted into the ear from being dislodged to other locations.

[0002] The tympanic membrane is the membrane located at the border between the external auditory canal and the middle ear. Otitis media is a disease in which inflammation occurs, such as when fluid accumulates in the middle ear. To treat this otitis media, a tympanic ventilation tube is surgically inserted through the tympanic membrane to allow air to flow between the middle ear and the external auditory canal inside and outside the tympanic membrane.

[0003] However, after treatment in which the tympanic membrane ventilation tube is penetrated into the tympanic membrane, as the portion of the tympanic membrane through which the tympanic membrane ventilation tube is penetrated recovers, a problem occurs in which the tympanic membrane ventilation tube is not fixed to the tympanic membrane and gradually moves out toward the external auditory canal.

[0004] The Eustachian tube, also known as the Eustachian tube, is a tube that connects the middle ear to the nasal cavity. Normally, the Eustachian tube is closed internally. However, if the tube is abnormally open, this is called a patulous Eustachian tube. To treat a patulous Eustachian tube, a surgical procedure is performed to close the tube by inserting a plug.

[0005] However, after treatment such as inserting a Eustachian tube plug into the Eustachian tube, a problem occurs in which the Eustachian tube plug gradually dislodges toward the nasal cavity due to the small pressure directed toward the nasal cavity of the nose each time the patient swallows saliva or food.

[0006] In addition, since obstructive eustachian tube obstruction may occur after Eustachian tube plug surgery, a separate tympanic membrane ventilation tube insertion surgery is often performed. Furthermore, while tympanic membrane ventilation tubes can be visually confirmed to be out of place through the external auditory canal, Eustachian tube plugs are inserted into the Eustachian tube inside the eardrum, making it difficult to visually confirm whether the Eustachian tube plug is properly inserted into the Eustachian tube or has dislodged toward the nasal cavity.

[0007] Accordingly, there is a need for a device that is simple in its surgical method and can maintain the inserted state of the tympanic membrane ventilation tube and Eustachian tube plug in the eardrum and Eustachian tube, respectively, without being dislodged in the direction of the external auditory canal and the direction of the nasal cavity.

[0008] The present invention provides a tympanic membrane ventilation tube plug assembly that is simple in its surgical method, can prevent a tympanic membrane ventilation tube inserted into the tympanic membrane from being dislodged toward the external auditory canal, and can prevent a tympanic membrane plug inserted into the Eustachian tube from being dislodged toward the nasal cavity.

[0009] According to one embodiment of the present invention, a tympanic membrane ventilation tube plug assembly maintains a tympanic membrane ventilation tube and a eustachian tube plug in a position in which they are inserted into the tympanic membrane and the eustachian tube, respectively, and can be prevented from being dislodged to other positions. The tympanic membrane ventilation tube plug assembly includes i) a tympanic membrane ventilation tube positioned through the tympanic membrane to allow air to flow between the external auditory canal on both sides of the tympanic membrane and the middle ear, ii) a eustachian tube plug inserted into the eustachian tube to close the interior of the eustachian tube, and iii) a connecting member connecting the tympanic membrane ventilation tube and the eustachian tube plug to each other to prevent them from being dislodged to other positions from positions in which the tympanic membrane ventilation tube and the eustachian tube plug are positioned.

[0010] The tympanic membrane ventilation tube includes an inner diameter having a predetermined thickness extending inward from the outer surface of the tympanic membrane ventilation tube to form a communication hole that provides a path for air to flow from one end to the other end within the tympanic membrane ventilation tube. A connecting member is connected at one end to the eustachian tube plug and at the other end to the inner diameter. The connecting member is connected to one end of the inner diameter.

[0011] A tympanic membrane ventilation tube plug assembly according to one embodiment of the present invention is provided with a plurality of connecting members. Each of the plurality of connecting members has one end joined to the tympanic membrane plug, and the other end joined to a first point, which is one end of an inner cervical section, and a second point, which is a point on one end of the inner cervical section different from the first point.

[0012] The length of the connecting member is longer than the horizontal distance from one end of the connecting member that is coupled to the tympanic membrane ventilation tube to the other end of the connecting member that is coupled to the eustachian tube plug.

[0013] The connecting member is formed of one of the following materials: silicon, nylon, and titanium. The length of the connecting member is 3 mm to 8 mm. The thickness of the connecting member is 0.2 mm to 1.2 mm.

[0014] The transfer plug and the connecting member can be formed as one piece.

[0015] By connecting the tympanic membrane ventilation tube and the Eustachian tube plug with a connecting member, the tympanic membrane ventilation tube inserted into the tympanic membrane can be prevented from dislodging toward the external auditory canal, and the Eustachian tube plug inserted into the Eustachian tube can be prevented from dislodging toward the nasal cavity. Furthermore, Eustachian tube plug insertion surgery and tympanic membrane ventilation tube insertion surgery can be easily performed simultaneously, and Eustachian tube plug removal surgery and tympanic membrane ventilation tube removal surgery can be easily performed simultaneously. Furthermore, it is possible to easily monitor whether the tympanic membrane ventilation tube is dislodged or not, as well as whether the Eustachian tube plug is dislodged.

[0024] Hereinafter, embodiments of the present invention will be described in detail with reference to the attached drawings so that those skilled in the art can easily implement the present invention. However, the present invention may be implemented in various different forms and is not limited to the embodiments described herein.

[0025] FIG. 1 is a cross-sectional view schematically illustrating the shape of a tympanic membrane ventilation tube plug assembly (100) (hereinafter referred to as the ventilation tube plug assembly (100)) according to one embodiment of the present invention. The ventilation tube plug assembly (100) of FIG. 1 is merely for illustrative purposes, and the present invention is not limited thereto. Accordingly, the shape of the ventilation tube plug assembly (100) may be modified differently.

[0026] As illustrated in FIG. 1, the ventilation tube plug assembly (100) is a medical device that can be inserted into the ear through surgery by a medical professional. The ventilation tube plug assembly (100) includes a tympanic membrane ventilation tube (110), an Eustachian tube plug (120), and a connecting member (130). Meanwhile, before describing the configuration of the ventilation tube plug assembly (100) according to the present embodiment, the names and meanings of the inside of the ear into which the ventilation tube plug assembly (100) is inserted will be described.

[0027] The tympanic membrane (tympanic membrane) is located at the border of the external auditory canal (ea) and the middle ear (me). It transmits sound to the cochlea by vibrating the auditory bones of the middle ear (me). The external auditory canal (external auditory meatus) is a tube that forms a passageway from the entrance of the ear to the eardrum (tm). The inside of the external auditory canal (ea) is covered with skin, and there are ear hairs and earwax to prevent foreign substances from entering. The middle ear (middle ear) refers to the internal space of the ear between the eardrum (tm) and the cochlea.

[0028] The Eustachian tube (Eustachian tube) is a tube that forms a passageway connecting the middle ear (ME) and the nasal cavity of the nose. The Eustachian tube (ET) functions to ventilate the middle ear (ME) and to equalize the pressure in the middle ear (ME) with the pressure in the external ear. The Eustachian tube (ET) is normally closed on the inside. However, if the Eustachian tube (ET) is abnormally always open, it is called a patulous Eustachian tube. The nasal cavity (Nus) refers to the empty space inside the nose located at the back of the nose. The nasal cavity functions to remove foreign substances in the air. This nasal cavity is connected to the Eustachian tube (ET).

[0029] As shown in Fig. 1, the configuration and effect of the ventilation pipe plug assembly (100) according to the present embodiment are described.

[0030] The tympanic membrane ventilation tube (110) is surgically inserted through the tympanic membrane (tm) to allow air to flow between the external auditory canal (ea) and the middle ear (me) on both sides of the tympanic membrane (tm). Meanwhile, the surgical method for inserting and removing the tympanic membrane ventilation tube (110) will be described later. The tympanic membrane ventilation tube (110) is formed in a hollow cylindrical shape and may be formed of a material such as plastic. The tympanic membrane ventilation tube (110) is horizontally arranged to penetrate the tympanic membrane (tm). For example, one end (the left end in FIG. 1) of the tympanic membrane ventilation tube (110) may extend toward the external auditory canal (ea), and the other end (the right end in FIG. 1) may extend toward the middle ear (me). Thus, air may flow between the external auditory canal (ea) and the middle ear (me) through the tympanic membrane ventilation tube (110). Meanwhile, this tympanic membrane ventilation tube (110) has a problem in that it may not be fixed to the tympanic membrane (tm) and may gradually be dislodged toward the external auditory canal (ea) as the portion of the tympanic membrane (tm) through which the tympanic membrane ventilation tube (110) is penetrated is restored.

[0031] The Eustachian tube plug (120) is inserted into the Eustachian tube (ET) to close the inside of the Eustachian tube (ET). Meanwhile, the surgical method for inserting and removing the Eustachian tube plug (120) will be described later. The Eustachian tube plug (120) can be surgically inserted into the Eustachian tube (ET) to treat the aforementioned patent Eustachian tube. The Eustachian tube plug (120) is formed in a cylindrical shape with a filled interior and can be formed of a material such as silicone. The Eustachian tube plug (120) is positioned to be inserted into the Eustachian tube (ET) through the entrance side of the Eustachian tube (ET). Thus, the inside of the Eustachian tube (ET) can be closed. Meanwhile, there is a problem that the Eustachian tube plug (120) can gradually be dislodged toward the nasal cavity due to a small pressure directed toward the nasal cavity whenever the patient swallows saliva or food.

[0032] As illustrated in FIG. 1, the connecting member (130) connects the tympanic membrane ventilation tube (110) and the Eustachian tube plug (120) to each other. For example, one end of the connecting member (130) may be coupled to the tympanic membrane ventilation tube (110), and the other end may be coupled to the Eustachian tube plug (120). Accordingly, the tympanic membrane ventilation tube (110) and the Eustachian tube plug (120) may be prevented from moving from a position where they are positioned to another position. For example, since the connecting member (130) connects the tympanic membrane ventilation tube (110) and the Eustachian tube plug (120), even if the portion of the tympanic membrane (tm) through which the tympanic membrane ventilation tube (110) penetrates is restored, the tympanic membrane ventilation tube (110) may be prevented from moving from the tympanic membrane (tm) toward the external auditory canal (ea). In addition, since the connecting member (130) connects the tympanic membrane ventilation tube (110) and the Eustachian tube plug (120), the Eustachian tube plug (120) can be prevented from gradually moving toward the nasal cavity by the small pressure directed toward the nasal cavity each time the patient swallows saliva or food. In other words, the connecting member (130) prevents the tympanic membrane ventilation tube (110) and the Eustachian tube plug (120) from moving to other positions and maintains the position in which they are inserted into the tympanic membrane (tm) and the Eustachian tube (et), respectively.

[0033] By connecting the tympanic membrane ventilation tube (110) and the Eustachian tube plug (120) to each other with a connecting member (130), the Eustachian tube plug (120) insertion surgery and the Eustachian tube ventilation tube (110) insertion surgery can be performed simultaneously without the need for a separate tympanic membrane ventilation tube (110) insertion surgery after the Eustachian tube plug (120) insertion surgery. In addition, by using the connecting member (130), not only the tympanic membrane ventilation tube (110) but also the Eustachian tube plug (120) can be simultaneously removed from the ear.

[0034] In addition, since the connecting member (130) is connected to the tympanic membrane ventilation tube (110) and the Eustachian tube plug (120), a medical professional can easily monitor not only whether the tympanic membrane ventilation tube (110) is displaced visually, but also whether the Eustachian tube plug (120) inserted into the Eustachian tube (et) inside the tympanic membrane (tm) is displaced. For example, whether the tympanic membrane ventilation tube (110) is displaced visually can be confirmed through the inside of the external auditory canal (ea), but since the Eustachian tube plug (120) is inserted into the Eustachian tube (et) inside the tympanic membrane (tm), there is a problem in that it is difficult to visually confirm whether it is properly inserted into the Eustachian tube (et) or displaced toward the nasal cavity. In contrast, since the eustachian tube plug (120) of the ventilation tube plug assembly (100) according to the present embodiment is connected to the tympanic membrane ventilation tube (110) through a connecting member (130), when the tympanic membrane ventilation tube (110) is properly positioned in the tympanic membrane (tm), it can be confirmed that the eustachian tube plug (120) is also properly inserted into the eustachian tube (et).

[0035] FIG. 2 schematically illustrates the appearance of the ventilation pipe plug assembly (100) of FIG. 1. That is, FIG. 2 illustrates the tympanic membrane ventilation pipe (110) and the eustachian tube plug (120) of the ventilation pipe plug assembly (100) being connected by a single connecting member (130). The structure of the ventilation pipe plug assembly (100) of FIG. 2 is merely for illustrative purposes, and the present invention is not limited thereto. Accordingly, the structure of the ventilation pipe plug assembly (100) may be modified differently.

[0036] As shown in FIG. 2, the tympanic membrane ventilation tube (110) includes an inner diameter portion (112) formed to have a predetermined thickness from the outer surface of the tympanic membrane ventilation tube (110) inward to form a communication hole (111) that provides a path for air to flow from one end to the other end inside the tympanic membrane ventilation tube (110).

[0037] The connecting member (130) is connected to the tympanic membrane plug (120) on one side (the right end of FIG. 2) and connected to the inner diameter (112) of the tympanic membrane ventilation tube (110) on the other side (the left end of FIG. 2). Here, the connecting member (130) can be connected to the front of one end of the inner diameter (112). Accordingly, the connecting member (130) does not block the communication hole (111) of the tympanic membrane ventilation tube (110), so that the passage of the communication hole (111) through which air is communicated can be secured without interference. Meanwhile, although not shown in the drawing, the connecting member (130) may also be connected to the outer circumferential surface of the inner diameter (112).

[0038] The connecting member (130) may be formed from a variety of materials that are flexible, durable, and do not cause adverse effects on the body. For example, the connecting member (130) may be formed from any one of silicone and nylon. Additionally, the connecting member (130) may be formed from titanium, a biocompatible material.

[0039] The length (l) of the connecting member (130) is longer than the horizontal distance (d) from one end of the connecting member (130) coupled to the tympanic membrane ventilation tube (110) to the other end of the connecting member (130) coupled to the Eustachian tube plug (120). For example, in a state where the tympanic membrane ventilation tube (110) penetrates the tympanic membrane (tm) and the Eustachian tube plug (120) is maintained in the position inserted into the Eustachian tube (et), the length (l) of the connecting member (130) extending in a bent shape is longer than the horizontal distance (d) from one end of the connecting member (130) to the other end.

[0040] The length (l) of the connecting member (130) may be 3 mm to 8 mm, and preferably 4 mm to 7 mm. When the length (l) of the connecting member (130) is 4 mm to 7 mm, the position where the tympanic membrane ventilation tube (110) penetrates the tympanic membrane (tm) and the position where the Eustachian tube plug (120) is inserted into the Eustachian tube (et) can be continuously maintained. If the length (l) of the connecting member (130) is less than 3 mm, there is a problem that the tympanic membrane ventilation tube (110) and the Eustachian tube plug (120) are easily detached from the tympanic membrane (tm) and the Eustachian tube (et). If the length (l) of the connecting member (130) exceeds 8 mm, there is a problem that the connecting member (130) is twisted and rolled inside the ear.

[0041] The thickness (t) of the connecting member (130) may be 0.2 mm to 1.2 mm, and preferably 0.3 mm to 1.1 mm. If the thickness (t) of the connecting member (130) is 0.3 mm to 1.1 mm, durability can be ensured so that the connecting member (130) does not break even when used for a long time. If the thickness (t) of the connecting member (130) is less than 0.2 mm, there is a problem that the connecting member (130) easily breaks when used for a long time. If the thickness (t) of the connecting member (130) exceeds 1.2 mm, there is a problem that the connecting member (130) is not suitable for the body structure in the middle ear (me) where the connecting member is located due to the excessive thickness.

[0042] The connecting member (130) can be formed integrally with the transfer plug (120). For example, if both the connecting member (130) and the transfer plug (120) are made of silicone, a mold having the shape of the connecting member (130) and the transfer plug (120) can be manufactured, and silicone can be poured into the mold, heated, and injected, thereby forming the connecting member (130) and the transfer plug (120) integrally.

[0043] Fig. 3 schematically illustrates the appearance of the ventilation pipe plug assembly (100) of Fig. 1. That is, Fig. 3 illustrates the tympanic membrane ventilation pipe (110) and the eustachian tube plug (120) of the ventilation pipe plug assembly (100) being connected by two connecting members (130). The structure of the ventilation pipe plug assembly (100) of Fig. 3 is merely for illustrative purposes, and the present invention is not limited thereto. Accordingly, the structure of the ventilation pipe plug assembly (100) may be modified differently.

[0044] As illustrated in FIG. 3, the connecting member (130) may be provided in a plurality of first connecting members (130a) and second connecting members (130b). For example, the first connecting member (130a) and the second connecting member (130b) may be connected at one end (the right end of FIG. 3) to the eustachian tube plug (120) or may be formed integrally with the eustachian tube plug (120). In addition, the other end (the left end of FIG. 3) of the first connecting member (130a) and the second connecting member (130b) may be connected at one end (the left end of FIG. 3) to a first point (112a) which is one of the ends of the inner diameter (112) of the tympanic membrane ventilation tube (110), and a second point (112b) which is a different point from the first point (112a) among the ends of the inner diameter (112). In this way, the bonding force and durability of connecting the tympanic membrane ventilation tube (110) and the Eustachian tube plug (120) to each other can be further strengthened by the plurality of first connecting members (130a) and second connecting members (130b). Meanwhile, although only two connecting members (130) are illustrated in the drawing, three or more connecting members (130) may be connected to the tympanic membrane ventilation tube (110) and the Eustachian tube plug (120), respectively.

[0045] As illustrated in FIG. 3, the first point (112a) of the inner diameter portion (112) connected to the first connecting member (130a) and the second point (112b) of the inner diameter portion (112) connected to the second connecting member (130b) may be points located on opposite sides with respect to the center of the communication hole (111). In other words, when the first connecting member (130a) is connected to the first point (112a) of the inner diameter portion (112), the second connecting member (130b) may be connected to the second point (112b) of the inner diameter portion (112) that is furthest away from the first point (112a). Accordingly, when the tympanic membrane ventilation tube (110) is pulled out of the ear through surgery and the Eustachian tube plug (120) is removed from the Eustachian tube (et) together with the tympanic membrane ventilation tube (110), the same stress is applied to the first connecting member (130a) and the second connecting member (130b) which are spaced apart from each other, so that an accident such as excessive stress being applied to either the first connecting member (130a) or the second connecting member (130b) and causing it to break or the like can be prevented.

[0046] Meanwhile, the surgical method for inserting and removing the tympanic membrane ventilation tube (110) and the Eustachian tube plug (120) is as follows.

[0047] The surgical method for inserting a tympanic membrane ventilation tube (110) and a Eustachian tube plug (120) is as follows: a local anesthetic is injected into the external auditory canal (ea) and the eardrum (tm), and a small perforation of about 2 mm is formed in front of the eardrum (tm) with a blade. Then, the position and condition of the ear-side entrance of the Eustachian tube (et) are confirmed through the perforation. Then, the Eustachian tube plug (120) is inserted into the ear-side entrance of the Eustachian tube (et). Afterwards, it is confirmed that the patient's symptoms of open otitis media disappear. Then, the tympanic membrane ventilation tube (110), which is connected to the Eustachian tube plug (120) through a connecting member (130), is placed directly over the perforated area of ​​the eardrum (tm). The surgical method for removing the tympanic membrane ventilation tube (110) and the Eustachian tube plug (120) is as follows: a local anesthetic is injected into the external auditory canal (ea) and the eardrum (tm). The tympanic membrane ventilation tube (110) is held with microforceps and pulled toward the external auditory canal (ea). Thus, the tympanic membrane ventilation tube (110) and the Eustachian tube plug (120) connected by the connecting member (130) can be removed together.
