Description

Mouthpiece for endoscope {MOUTHPIECE FOR ENDOSCOPE}

The present invention relates to an endoscopic mouthpiece, and more specifically, to prevent the patient's saliva from spewing out through the endoscope insertion port during an endoscopic procedure, and to remove the endoscope from the patient after an endoscopic procedure easily and without being contaminated with the patient's saliva. This relates to an endoscopic mouthpiece that can be safely removed.

In general, an endoscope is a medical device used to medically examine the inside of the human body and to diagnose or treat lesions by observing internal organs such as intestines or body cavities.

Using an endoscope, a doctor can examine a patient's internal organs directly without performing surgery, making it possible to detect conditions that were not detected through ultrasound or X-ray examination and treat them early.

Depending on the purpose of use and the area to be examined, these endoscopes include esophagoscopes, bronchoscopes, and gastroscopes, which insert the endoscope through the mouth and examine the organ to be observed. In addition, the endoscope is inspected by cutting a part of the human body and inserting the endoscope there. There are thoracoscopes, laparoscopes, etc., as well as special endoscopes designed to specifically observe or treat specific organs.

Typically, in order to use an esophagoscope, bronchoscope, gastroscope, etc., an endoscope is inserted through the patient's oral cavity and esophagus. In this case, an endoscope mouthpiece is used to facilitate insertion of the endoscope.

The endoscopic mouthpiece is made to be supported around the patient's mouth and has a main body with a through hole formed in the center, an endoscope guide part formed in the through hole of the main body to guide the insertion of the endoscope, and a rear surface of the main body. It consists of a tooth support part formed in the patient's front teeth to fix the main body.

The use of such an endoscopic mouthpiece allows the patient to open his mouth and bring the main body into contact with the surroundings of the patient's mouth. When the patient's front teeth bite the tooth support part, the main body is supported by the mouth and teeth, allowing the patient's mouth to continuously open.

In this state, when the endoscope is inserted through the through hole of the main body, the endoscope is inserted through the endoscope guide portion and through the patient's oral cavity and esophagus. At this time, lesions in areas such as the esophagus, bronchial tubes, or stomach are examined.

With such a conventional mouthpiece, during an endoscopic procedure, the patient's saliva spews out through the endoscope insertion port, which can infect the procedure site and the operator.

In addition, when removing the endoscope from a patient after an endoscopic procedure, with a conventional mouthpiece, the operator must hold and pull out the part where the patient's saliva is stained, which not only raises the risk of infection, but also causes the patient's teeth to be damaged as the operator rushes to minimize contact as much as possible. There was a problem with damage.

Republic of Korea registered patent 10-1730544 (2017.04.20.)

The present invention was developed in consideration of the above problems, and the purpose of the present invention is to provide an endoscopic mouthpiece that prevents the patient's saliva from spewing out through the endoscope insertion port during endoscopic procedures.

Another object of the present invention is to provide an endoscopic mouthpiece that can be easily and safely removed without being contaminated with the patient's saliva when removing the endoscope from the patient after an endoscopic procedure.

According to the feature for achieving the above-mentioned purpose, the endoscopic mouthpiece is formed with a through hole larger than the diameter of the endoscopic device, and the patient's saliva flows through the through hole when the endoscopic device is inserted into the through hole. A plate with a rubber shield attached to prevent blowing out; A tooth support portion extending into the oral cavity around the through hole on the back of the plate to support the upper and lower teeth in an open mouth state, and having a radially protruding tooth locking jaw formed at the rear end to prevent the teeth from being separated; a tongue support portion extending from the bottom of the tooth support portion to the upper surface of the tongue to limit tongue movement during an endoscopic procedure; and a handle protruding from the front of the plate around the through hole so that the plate can be held in a position that is not contaminated with the patient's saliva.

In addition, it is preferable that a tooth seating pad is installed in the tooth support portion to prevent damage to the teeth through a cushioning effect when the teeth are seated.

In addition, it includes a rotating body made of a curved surface that is in contact with the inner periphery of the tooth support and can be rotated, and a ring structure connected to one end of the rotating body and exposed to the front of the plate, and forming the through hole and the rubber shielding film on the inside. Preferably, the handle is installed on the front of the ring structure, and the tooth locking jaw is formed at the other end of the rotating body by being separated into an upper tooth locking jaw corresponding to the upper teeth and a lower tooth locking jaw corresponding to the lower teeth.

In addition, the tongue support portion forms a groove that is open on one side to allow entry of the rotating body to avoid interference with the lower tooth locking jaw due to rotation of the rotating body, and is preferably arranged to be spaced apart from the tooth supporting portion.

According to the endoscopic mouthpiece according to the present invention, there is an effect of preventing infection to the procedure site and the operator by preventing the patient's saliva from spewing out through the endoscope insertion port during the endoscopic procedure.

In addition, according to the invention, when removing the endoscope from a patient after an endoscopic procedure, it can be easily and safely removed without contacting the patient's saliva, so the operator does not feel reluctant to remove the endoscope after the procedure and there is no concern about damaging the patient's teeth. There is an advantage to being able to remove it.

Therefore, the present invention is not limited to the presented embodiments, and is understood by those skilled in the art to which the present invention pertains, within the technical spirit of the present invention and the technical equivalents described in the claims below. Various modifications and changes are possible.

<First embodiment>

In the following, a first embodiment of the present invention will be described in detail with reference to the attached drawings.

Figure 1 is a perspective view showing the front part of the mouthpiece according to the first embodiment of the present invention, and Figure 2 is a perspective view showing the rear part of the mouthpiece according to the first embodiment of the present invention. In Figure 1, a tooth seating pad is mounted on the tooth support portion, and in Figure 2, the tooth seating pad is shown in a separated state.

As shown, the mouthpiece according to the present invention includes a plate (1), a tooth support portion (4), a tongue support portion (6), and a handle (7).

The plate 1 extends to the patient's mouth and its surroundings and is curved to match the shape of the face, and serves to fix the position of the mouthpiece during an endoscopic procedure by contacting the face. Therefore, the plate (1) should cover the area around the patient's mouth, preferably from the bottom of the nose to the top of the chin. In addition, since the plate 1 may be stained with saliva, digestive secretions, or medicinal solutions, it is preferably made of a waterproof material for convenience in use and management.

A through hole 2 through which endoscopic equipment can be inserted is formed in the center of the plate 1, and the patient's saliva is ejected through the through hole 2 when an endoscopic device is inserted into the through hole 2. A rubber shield (3) is attached to prevent this. The rubber shielding membrane (3) is structured so that the endoscopic instrument can be easily inserted and adheres as closely as possible to the side of the endoscopic instrument. To this end, in this embodiment, the rubber shielding membrane (3) is cut in an X shape. It is being exemplified.

Band rings (1a) are formed on both sides of the plate (1), and a hair band (B) is attached to the band ring (1a) to secure the plate (1) to the patient's head. At this time, the length of the hair band can be adjusted appropriately to fit the size of the patient's head.

The tooth support portion 4 supports the upper and lower teeth to maintain the patient's mouth open when the mouthpiece is inserted into the oral cavity, and extends from the back of the plate 1 into the oral cavity. The tooth support portion 4 may be configured in a cylindrical shape, and the portion corresponding to the upper and lower teeth is preferably configured in a flat shape for stable seating of the upper and lower teeth.

In addition, a radially protruding tooth locking protrusion 5 is formed at the rear end of the tooth support portion 4 to prevent the teeth seated on the tooth support portion 4 from being accidentally separated. The tooth locking protrusion 5 is formed radially and need not be formed around all directions, but is preferably formed at the point where the upper and lower teeth are seated.

In addition, the tooth support portion 4 may be made of soft materials such as silicone, polyurethane, and natural rubber to provide a cushioning effect when the tooth is seated. Separately from the tooth support portion 4, teeth are made of soft materials for this role. A seating pad (8) may be installed on the tooth support portion (4). At this time, the tooth seating pad (8) is installed surrounding the difference support portion and has a thickness that does not protrude from the tooth locking protrusion (5) so that it does not fall off arbitrarily when attached to or removed from the oral cavity.

The tongue support portion 6 extends from the lower end of the tooth support portion 4 to the upper surface of the tongue and covers a portion of the tongue. This tongue supporter (6) is intended to limit the movement of the tongue during an endoscopic procedure. If the patient's tongue moves during an endoscopic procedure, problems such as the endoscopic equipment not being inserted correctly may occur, so press the tongue with the tongue supporter (6). It is fixed so that the procedure can be performed smoothly.

The handle 7 is used to hold the mouthpiece so that it can be moved in and out of the patient's mouth without directly holding the plate 1, and is formed to protrude from the front of the plate 1. In other words, the plate 1 may be contaminated with the patient's saliva during an endoscopic procedure, so hands may become contaminated when removing the mouthpiece from the oral cavity. To prevent this phenomenon, a protruding plate protrudes from the front of the plate 1. The handle 7 is formed so that the plate 1 can be held in a position that is not contaminated with the patient's saliva.

The handles 7 are formed in pairs around the through hole 2 so that they can be gripped at one end and the other end of the plate 1 with the thumb and index finger.

Next, the operation of the mouthpiece according to the first embodiment will be described.

Figure 3 is a perspective view showing a state in which the mouthpiece according to the first embodiment is installed in the oral cavity.

Hold the mouthpiece with the handle (7) and, with the patient's mouth open, insert the tooth support portion (4) and tongue support portion (6) into the patient's constitution so that the plate (1) is in close contact with the face. At this time, the tongue support part 6 is placed on the upper surface of the tongue, the upper end of the tooth support part 4 is placed to correspond to the upper teeth, and the lower end is arranged to correspond to the lower teeth, and then the mouth is closed. In this case, the patient's mouth is open, but the upper and lower teeth are seated on the tooth support (4), so the patient can comfortably keep his mouth open. Since a tooth seating pad (8) is mounted on the tooth support portion (4), teeth can be seated on the tooth seating pad (8) without impact due to the cushioning effect of the tooth seating pad (8).

Then, hair bands (B) are attached to the band rings (1a) on both sides of the plate (1) and placed around the patient's head to pressurize the mouthpiece so that it does not fall out of the patient's mouth.

The endoscopic equipment enters the oral cavity through the rubber shield (3) formed in the through hole (2). At this time, the rubber shield (3) is cut in an

When the endoscopic procedure is completed, grasp the handle (7), open the patient's mouth slightly more, and remove the mouthpiece from the oral cavity. At this time, the plate (1) may be contaminated with the patient's saliva during the endoscopic procedure, so your hands may be contaminated when you hold the plate (1). However, the handle (7) protrudes from the plate (1) and the handle (7) Since the gripping position is on the opposite side of the through hole (2), the mouthpiece can be removed by gripping an area that is not contaminated with saliva.

<Second Embodiment>

Next, a second embodiment of the mouthpiece according to the present invention will be described. In this embodiment, the same drawing numbers are used for components corresponding to the first embodiment.

Figure 4 is a perspective view showing the front part of the mouthpiece according to the second embodiment of the present invention, Figure 5 is a perspective view showing the rear part of the mouthpiece according to the second embodiment, and Figure 6 is a perspective view showing the front part of the mouthpiece according to the second embodiment. This is an exploded perspective view of the mouthpiece. And Figure 7 is a rear perspective view showing a state in which the handle is turned on the mouthpiece according to the second embodiment.

As shown, in the mouthpiece according to the second embodiment, a pair of handles (7) are rotated to change the position of the tooth locking jaw (5) so that the mouthpiece is attached to the tooth locking jaw (5) when inserting and removing the mouthpiece. In addition to preventing damage to the teeth, the handle (7) has the feature of being able to remove it without the patient's saliva.

For this purpose, the handle (7) and the tooth locking jaw (5) are connected and configured to be rotated as one piece, and this is achieved through the rotating body (9) and the ring structure (10).

In more detail, the rotating body (9) is in contact with the inner periphery of the tooth support portion (4) and is made of a rotatable curved surface. At this time, since it is desirable to maintain a state in contact with the inner periphery of the tooth support portion 4 when the rotating body 9 is rotated, the inner periphery of the tooth support portion 4 may be configured to have a circular cross-section. In addition, the rotating body 9 may be configured in a cylindrical shape like the tooth supporting part 4, but it is preferable to be formed separately in the longitudinal direction of the tooth supporting part 4 to facilitate installation on the tooth supporting part 4. do.

A ring structure 10 is connected to one end of this rotating body 9, and a kick stop is formed at the other end.

The ring structure 10 is exposed to the front of the plate 1 at one end of the rotating body 9, and the through hole 2 and the rubber shielding film 3 are formed inside it, and a handle ( 7) is formed. Therefore, when the handle 7 is held and rotated in one direction, the ring structure 10 rotates and the rotating body 9 connected thereto can also be rotated in the same direction.

The tooth locking jaw 5 is formed to protrude from the other end of the rotating body 9 to correspond to the upper and lower teeth. That is, the tooth locking protrusion 5 is not formed around the entire tooth support portion 4, but is formed separately into an upper tooth locking protrusion 5a corresponding to the upper teeth and a lower tooth engaging protrusion 5b corresponding to the lower teeth. . Therefore, a structure is provided in which the tooth locking jaw (5) can be rotated integrally with the rotation of the handle (7).

In addition, the tooth locking jaw (5) is formed to protrude from the tooth support portion (4), so that the ring structure (10) on which the handle (7) is formed is coupled to the plate (1) and the tooth support portion (4). .

In addition, since the tongue support portion 6 extends from the tooth support portion 4 into the oral cavity, in the case of the configuration shown in FIG. 2 of the first embodiment, it is located in the movement line of the lower tooth locking jaw 5b and causes interference. Therefore, in the second embodiment, as shown in FIG. 5, the tongue support portion 6 forms a groove portion 6a open on one side to allow entry of the rotating body 9, and the tooth support portion 4 It is placed away from the

With this configuration, when inserting the mouthpiece into the patient's oral cavity, the handle 7 is placed on the left and right sides of the plate 1, as shown in FIG. 4, so that the upper and lower teeth are caught when the mouth is opened. It can be seated on the tooth support (4) without the jaw (5). In this state, when the handle 7 is rotated 90°, as shown in FIG. 7, the ring structure 10 and the rotating body 9 rotate and the upper tooth locking jaw 5a and the lower tooth locking jaw 5b are respectively It is placed at the rear of the upper and lower teeth to prevent the upper and lower teeth from falling out. At this time, when the rotating body (9) corresponding to the lower tooth locking protrusion (5b) is inserted into the groove portion (6a) and reaches the end of the groove portion (6a), it no longer rotates and the upper and lower tooth locking protrusions (5a) are connected to each other. Make sure (5b) is accurately placed on the upper and lower teeth, respectively.

When the endoscopic procedure is completed, if the handle 7 is rotated 90° in the reverse direction, the lower tooth locking jaw 5b is separated from the groove 6a and the upper tooth locking jaw 5a is also positioned to deviate from the rear end of the upper teeth. By pulling the handle (7), the mouthpiece can be easily dismantled within the patient's mouth without damaging the teeth.

As above, the rights of the present invention are not limited to the embodiments described above but are defined by the claims, and various modifications and modifications can be made by those skilled in the art within the scope of the rights set forth in the claims. It is self-evident that you can do this.
