Description

Technical Field

[0001] This utility model belongs to the field of mouthpiece technology, specifically a mouthpiece for gastroscopy. Background Technology

[0002] A mouthpiece is frequently used during gastroscopy in gastroenterology to assist with the examination. During a gastroscopy, the endoscope is inserted into the digestive tract through the mouth. The mouthpiece prevents the patient from unconsciously biting down during the procedure, which could damage the oral mucosa, teeth, and gums.

[0003] Because the support tube and diameter of a mouthpiece are basically the same, and different patients have different mouth opening sizes when receiving treatment, patients with diseases such as oral lichen planus or pemphigus may be unable to open their mouths wide due to pain. Continuing to use a conventional mouthpiece will cause severe discomfort because the patient's mouth opening angle is too small.

[0004] Therefore, this utility model provides a mouthpiece for gastroscopy. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A mouthpiece for gastroscopy, comprising a mouthpiece body; a plurality of sliding columns are slidably connected within the mouthpiece body; a fixing plate is fixedly installed at one end of each sliding column within the mouthpiece body; a connecting plate is fixedly installed at the end of each sliding column away from the fixing plate; both the fixing plate and the connecting plate are arc-shaped. A plurality of limiting grooves are formed on the surface of each sliding column, and a limiting rod is slidably connected within the mouthpiece body.

[0007] Furthermore, both ends of the connecting plate are slidably connected to arc-shaped extension plates, and springs are fixedly installed inside both ends of the connecting plate, with one end of each spring fixedly connected to the extension plate.

[0008] Furthermore, a collar made of rubber is fixedly sleeved on the surface of the limiting rod.

[0009] Furthermore, two symmetrically arranged rotating plates are rotatably connected within the limiting groove, and the rotating plates are made of anti-slip material.

[0010] Furthermore, the fixed plate has several slots on the side away from the sliding column, and a rubber ball is wedged in the slot, with the center of the rubber ball located in the slot.

[0011] Furthermore, a rectangular plate is fixedly installed at one end of the fixing plate, and an anti-slip pad is fixedly installed on one side of the rectangular plate.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. The gastroscopy mouthpiece of this utility model features a sliding limiting rod that slides away from the sliding column, accompanied by a rubber collar. The collar increases friction and positions the limiting rod. A rectangular plate then moves the fixing plate, sliding column, and connecting plate. The height of the sliding column and connecting plate can be adjusted to accommodate different patients' oral cavity opening angles. After reaching the appropriate height, the sliding limiting rod returns to its original position, allowing the limiting rod to push open a rotating plate into the limiting groove. The rotating plate, made of a non-slip, flexible material, increases friction while protecting the unused limiting groove, effectively reducing the entry of impurities and facilitating compatibility with the limiting rod. This structural design allows for rapid adjustment of the mouthpiece's body diameter, eliminating the fixed diameter and adapting to different patient oral cavity opening angles. This effectively solves the problem of traditional mouthpieces with larger body diameters causing discomfort to patients.

[0014] 2. The mouthpiece for gastroscopy described in this utility model allows the endoscope to pass through the mouthpiece body and enter the patient's body after the mouthpiece body is installed in the patient's mouth. At this time, the rubber ball on the fixing plate assists the movement of the endoscope and protects the surface of the endoscope, reducing direct friction between the endoscope surface and the mouthpiece body, thus preventing the endoscope surface from being easily worn and requiring frequent replacement.

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] like Figures 1 to 6 As shown in the embodiment of this utility model, a mouthpiece for gastroscopy includes a mouthpiece body 1. Several sliding posts 2 are slidably connected within the mouthpiece body 1. A fixing plate 3 is fixedly installed at one end of each sliding post 2 within the mouthpiece body 1, and a connecting plate 4 is fixedly installed at the end of each sliding post 2 away from the fixing plate 3. Both the fixing plate 3 and the connecting plate 4 are arc-shaped. Several limiting grooves 6 are formed on the surface of each sliding post 2, and limiting rods 5 are slidably connected within the mouthpiece body 1. Arc-shaped extension plates 8 are slidably connected to both ends of the connecting plate 4, and springs 7 are fixedly installed within both ends of the connecting plate 4, with one end of each spring 7 fixedly connected to the extension plate 8.

[0025] Specifically, a collar 9, made of rubber, is fixedly fitted onto the surface of the limiting rod 5. Two symmetrically arranged rotating plates 10, made of anti-slip material, are rotatably connected inside the limiting groove 6. A rectangular plate 13 is fixedly installed at one end of the fixing plate 3, and an anti-slip pad is fixedly installed on one side of the rectangular plate 13.

[0026] During operation, when a gastroenterology patient undergoes a gastroscopy, the mouthpiece body 1 is used. Initially, the mouthpiece body 1 is in its smallest position, suitable for patients with a small oral cavity opening angle. When the smallest position is unsuitable for the patient, the sliding limit rod 5, along with its rubber collar 9, slides away from the sliding post 2. The collar 9 increases friction and positions the limit rod 5. The rectangular plate 13 then moves the fixing plate 3, the sliding post 2, and the connecting plate 4. By adjusting the height of the sliding post 2 and the connecting plate 4, the mouthpiece body can accommodate different patients' oral cavity opening angles. After adjusting to the appropriate height, the sliding limit rod 5 resets, allowing it to push open the rotating plate 10 and enter the limiting groove 6. The rotating plate 10 is made of a non-slip, flexible material; while increasing friction with the limit rod 5, it also protects the unused limiting groove 6, effectively reducing the entry of impurities and facilitating its use with the limit rod 5.

[0027] The structure designed above enables rapid adjustment of the diameter of the mouthpiece body 1, so that the mouthpiece body 1 is no longer a fixed diameter, thereby adapting to the angle of the patient's mouth opening and effectively solving the problem of the large diameter of the traditional mouthpiece body 1 causing discomfort to the patient.

[0028] The fixed plate 3 has several slots 11 on the side away from the sliding column 2. A rubber ball 12 is wedged in the slot 11, and the center of the rubber ball 12 is located in the slot 11.

[0029] During operation, after the mouthpiece body 1 is installed in the patient's mouth, the endoscope will pass through the mouthpiece body 1 and enter the patient's body. At this time, the rubber ball 12 on the fixing plate 3 will assist the movement of the endoscope. At the same time, the rubber ball 12 will protect the surface of the endoscope and reduce the direct friction between the surface of the endoscope and the mouthpiece body 1, which would cause the surface to wear easily and require frequent replacement.

[0030] Working principle: When a gastroenterology patient undergoes a gastroscopy, the mouthpiece body 1 is used. Initially, the mouthpiece body 1 is in its smallest position, suitable for patients with a small oral cavity opening angle. When the smallest position is unsuitable for the patient, the sliding limit rod 5, along with its rubber collar 9, slides away from the sliding post 2. The collar 9 increases friction and positions the limit rod 5. The rectangular plate 13 then moves the fixing plate 3, the sliding post 2, and the connecting plate 4. By adjusting the height of the sliding post 2 and the connecting plate 4, the mouthpiece body can be adapted to different patients' oral cavity opening angles. After adjusting to the appropriate height, the sliding limit rod 5 resets, allowing it to push open the rotating plate 10 and enter the limiting groove 6.

[0031] After the mouthpiece body 1 is installed in the patient's mouth, the endoscope will pass through the mouthpiece body 1 and enter the patient's body. At this time, the rubber ball 12 on the fixing plate 3 will assist the movement of the endoscope, and at the same time, the rubber ball 12 will protect the surface of the endoscope.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
