Description

Technical Field

[0001] The utility model belongs to the technical field of oral cavity openers for gastroscopy, in particular to a mouth opener for gastroscopy. Background Art

[0002] During a gastroscopy, the patient first lies on his left side, and then the doctor inserts the gastroscope from the mouth and into the stomach through the esophagus for examination. During the insertion of the gastroscope, a mouth opener is generally used to open the patient's mouth. After opening, it is convenient to fix the patient's upper and lower teeth to avoid the patient biting due to reflex during the insertion of the gastroscope, which may cause damage to the gastroscope or injury to the patient's mouth.

[0003] Most of the currently available mouth openers are composed of two upper and lower support plates, which are connected together by fixings, and a gap is left between the two support plates for inserting a gastroscope. When in use, the upper teeth are bitten on one of the support plates and the lower teeth are bitten on the other support plate, and then the gastroscope is inserted into the patient's gastrointestinal tract through the gap between the two support plates. Therefore, the design of the two support plates can avoid the problem of inconvenience caused by the teeth biting on the gastroscope. However, during gastroscopy, if the operation is not performed under anesthesia, if the patient feels pain during the operation, the movement of the mouth may cause the support plate to fall out of the mouth. If the patient is operated under general anesthesia, the patient is unconscious, and the gastroscope will contact the support plate during movement, so the support plate may also fall out of the mouth, and therefore the teeth in the mouth cannot be stably opened.

[0019] The present invention will be further described below through specific embodiments in conjunction with the accompanying drawings, but this does not limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.

[0020] Example

[0021] The present embodiment describes a gastroscopy stent, such as Figure 1As shown, the support tube 1 is horizontally arranged and divided into left and right halves. The left half of the support tube 1 is the occlusal portion for teeth to occlude. During gastroscopy, the interior of the support tube 1 is used for inserting the gastroscope. During use, the upper and lower teeth bite the outer wall of the left half of the support tube 1, and the right half of the support tube 1 is located outside the mouth. The gastroscope then passes through the interior of the support tube 1 and enters the gastrointestinal tract, thereby preventing the teeth from biting the gastroscope during the operation.

[0022] like Figure 1 and Figure 2 As shown, the right half of the support tube 1 is provided with a sliding sleeve 8, which is sleeved on the support tube 1; a fixing plate 6 is fixed to the outer wall of the sliding sleeve 8; a tape 4 for adhering to the skin is provided on the left side wall of the fixing plate 6, and an annular groove is provided on the left side wall of the fixing plate 6, in which a limiting ring 5 for pressing the edge of the tape 4 therein is provided; the limiting ring 5 and the fixing plate 6 are both made of elastic material; this scheme as a whole constitutes an adhesive component that can be adhered to the patient's face; according to Figure 2 The circumference of the circumference of the slit 5 is 400mm, and the circumference of the slit 5 is 400mm. Figure 1 When the adhesive tape 4 is fixed, the side with the adhesive on the adhesive tape 4 is Figure 1The left side wall of the middle adhesive tape 4, the edge of the left side wall of the adhesive tape 4 and the right side wall are not coated with glue; preferably, the left side wall of the adhesive tape 4 is provided with release paper, which is an existing known product and can prevent the glue on the adhesive tape 4 from adhering to other objects when the adhesive tape 4 is not in use; the installation method of the above-mentioned adhesive tape 4 is convenient for disassembly and installation, so it is convenient to replace the adhesive tape 4; when in use, first place the edge of the adhesive tape 4 in the position of the annular groove, and then squeeze the limiting ring 5 into the annular groove to press the edge of the adhesive tape 4 into the annular groove, so as to achieve the purpose of fixing the adhesive tape 4; then tear off the release paper on the adhesive tape 4, and then the adhesive tape 4 can be adhered to the patient's skin, thereby adhering the fixing plate 6 to the patient's skin. At this time, because the fixing plate 6 is fixed to the support tube 1 by the sliding sleeve 8, the position of the support tube 1 can be limited to prevent the support tube 1 from falling off from the oral cavity during use, thereby avoiding the problem of not being able to stably open the oral cavity;

[0023] In a specific implementation process, the adhesive tape 4 in the adhesive component can also be AB glue, which has good viscosity, can fit closely to the skin, is not easy to fall off, and is easy to remove without damaging new tissue; it can also be reused many times and still maintains its viscosity after washing; for example, the glue on the chest patch around us can be made of AB glue;

[0024] The fixing plate 6 is made of silicone material, and the limiting ring 5 is made of silicone material. Since the limiting ring 5 and the fixing plate 6 are made of silicone material, it is easy to bend the limiting ring 5 and the fixing plate 6, and it also has a certain hardness, so it is easy to fit the fixing plate 6 on the skin of the patient's face;

[0025] like Figure 1 and Figure 2 As shown, the left half of the support tube 1 is covered with a mouthpiece 2, and a groove is provided on the mouthpiece 2 for easy biting of the teeth; the groove is provided along the circumference of the mouthpiece 2 in an annular structure; the inner side wall of the mouthpiece 2 is fixed to the outer side wall of the support tube 1; when in use, the upper and lower teeth are bitten into the groove, thereby limiting the position of the teeth and making them bite more stably on the support tube 1;

[0026] like Figure 1 and Figure 3 As shown, a mouth pad 3 for protecting the oral cavity is placed on the outer wall of the mouth cover 2; the mouth pad 3 is made of sponge; therefore, the side wall of the mouth cover 2 that contacts the teeth is replaced by the mouth pad 3, so that the mouth pad 3 can play a cushioning role, allowing the teeth and gums to bite the mouth cover 2 more comfortably, providing a comfortable feeling during use; when the mouth pad 3 is installed, it is put on the mouth cover 2 like a pillowcase, so that the mouth pad 3 is easy to remove and install later; at the same time, the mouth pad 3 can also be made of cotton;

[0027] like Figure 1When the teeth are bitten in the grooves on the mouth cover 2, the position of the fixing plate 6 can be adjusted, thereby adjusting the position of the adhesive tape 4. Because the teeth are bitten in the grooves on the mouth cover 2, each person's oral structure is different, such as tooth arrangement, shape and size of the jaw, etc.; therefore, the fixing plate 6 may not fit well on the face. Therefore, by adjusting the positions of the sliding sleeve 8 and the fixing plate 6, it is convenient to fit the fixing plate 6 on the face according to different oral structures, so that the adhesive tape 4 is stably adhered to the face. When the sliding sleeve 8 is moved to the appropriate position, the screw is tightened so that the screw is pressed against the outer wall of the support tube 1, and the position of the sliding sleeve 8 can be limited.

[0028] During the specific use process: first, bite the groove on the mouthpiece 2 with the teeth, then adjust the position of the sliding sleeve 8 to make the fixing plate 6 fit the patient's facial skin, and then use the tape 4 fixed on the fixing plate 6 to stick it to the face, and then the gastroscope is inserted into the gastrointestinal tract from the support tube 1; during this use process, the support tube 1 can prevent the support tube 1 from falling out of the oral cavity through the cooperation between the tape 4, the sliding sleeve 8 and the fixing plate 6, so that the support tube 1 can stably support the teeth in the oral cavity.
