Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a mouthpiece for endoscopic surgery. Background Art

[0002] Endoscopic examination and minimally invasive treatment is to use a gastroscope to probe the esophagus and stomach cavity through the mouth, and use auxiliary equipment to achieve the purpose of precise diagnosis and removal of lesions inside or outside the digestive tract. With the rapid development and promotion of minimally invasive technology of digestive endoscopy, the development of endoscopic treatment projects has become more and more mature. In clinical applications, medical staff are also constantly exploring better treatment plans based on actual clinical experience.

[0003] In conventional endoscopic clinical surgery, a mouthpiece is required. The structure of an existing mouthpiece generally includes a lip plate, a mouthpiece tube, and a bandage. Expansion holes for limiting the position of the endotracheal tube are opened on both sides of the lip plate, and the two ends of the bandage are fixed on the edge of the expansion hole. In actual clinical operation, after the endotracheal tube is inserted, the expansion hole on one side of the lip plate needs to be cut open with scissors, and then the endotracheal tube is inserted into the expansion hole along the gap, and then the patient is asked to bite the mouthpiece. The operation is complicated, and after the side of the expansion hole is cut open, if the tension of the bandage is too large, it is easy to fall off from the gap cut by the expansion hole, affecting the fixation of the mouthpiece.

[0004] To this end, we designed a new type of bite block for endoscopic surgery. The expansion hole on the side of the lip plate is designed to be snap-on, which facilitates the opening and closing of the expansion hole, facilitates the rapid installation of tracheal intubation and straps, and avoids the problem of the straps falling off. The structure is simple and will not excessively increase the processing cost of the bite block, making it highly practical. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example 1

[0022] See also Figure 1-5 The present embodiment provides a mouthpiece for endoscopic surgery, including a lip plate 1 and a bandage 5. An endoscope port 3 is provided on the lip plate 1, and a mouthpiece tube 2 communicating with the endoscope port 3 is provided at the lower end of the lip plate 1. Expansion holes 4 are provided on both sides of the lip plate 1, and both ends of the bandage 5 are provided on the side edges of the expansion hole 4. An opening 8 is provided on the side edge of the expansion hole 4, and an endotracheal tube can be placed in the expansion hole 4 through the opening 8. A clamping head 6 for closing the opening 8 and fixing the bandage 5 is detachably provided on the side edge of the expansion hole 4; specifically, blocks 7 fixedly connected to the side edges of the expansion hole 4 are provided on both sides of the opening 8, and a clamping groove 9 is provided on the inner side of the block 7. Clamping strips 11 are provided on both sides of the clamping head 6, and the clamping strips 11 are clamped in the clamping grooves 9.

[0023] The card slot 9 is arranged on the inner side of the stopper 7. When the binding belt 5 generates a pulling force on the card head 6, the stability of the connection between the card head 6 and the card slot 9 can be further ensured to prevent the card head 6 from falling off.

[0024] like Figure 3 As shown, in order to make the card bar 11 in the card slot 9 more stable, a first baffle 10 is provided in the card slot 9, and a second baffle 12 engaged with the first baffle 10 is provided on the card bar 1. The positions of the first baffle 10 and the second baffle 12 correspond to each other, which is a conventional design familiar to those skilled in the art and will not be described in detail in this application.

[0025] At the same time, in order to facilitate the fixation of the strap 5, an adhesive tape 13 is provided on the inner side of the end of the strap 5, which is used to fix the strap 5 to the side of the expansion hole 4. When in use, the strap 5 is passed around the side of the expansion hole 4, and the adhesive tapes 13 on the inner side are adhered to each other, so that the strap 5 can be fixed; as a conventional design familiar to those skilled in the art, the adhesive tape 13 can be selected from Velcro, or it can be replaced by a buckle with the same effect, which is a conventional structure and can be obtained by custom processing, and this application will not be specifically limited.

[0026] During clinical operation, after the endotracheal tube is inserted, the medical staff first presses the clamp head 6 inward to separate the clamping strip 11 from the clamping slot 9, removes the clamp head 6, opens the opening 8, moves the mouthpiece to clamp the endotracheal tube into the expansion hole 4, then clamps the clamp head 6, lets the patient bite the mouthpiece tube 2, and then uses tape to further fix the endotracheal tube to the patient's face, and then inserts the endoscope into the body through the endoscope port 3.

[0027] It should be noted that, in actual processing, as common knowledge among technicians in this field, the material of the mouthpiece is considered to be a tough plastic material to facilitate the disassembly and assembly of the clamp; at the same time, considering that after the endotracheal tube is inserted into the expansion hole, a certain amount of space needs to be reserved to facilitate the nursing staff to insert the clamp, so the area of ​​the expansion hole can be expanded according to demand, and this application will no longer limit and elaborate.

[0028] In addition, the present application does not limit the number of the clamp heads 6, and the clamp heads 6 can be set on one side, and the clamp heads 6 can also be set on the expansion holes 4 on both sides; taking into account the actual application and for the convenience of use by nursing staff, during actual processing, it should be preferred to set the clamp heads 6 on the expansion holes 4 on both sides, and the straps 5 can be tied to the clamp heads 6; at the same time, as a conventional design, after the clamp heads 6 are fixed, their end faces on both sides should be in contact with the end faces of the block 7 to prevent the straps 5 from being stuck in the gap. Example 2

[0029] On the basis of Example 1, during clinical operation, after the endotracheal tube is inserted into the expansion hole 4, in order to fix the endotracheal tube, it is necessary to fix the endotracheal tube to the patient's face with tape, which will cause discomfort to the patient. Figure 6 As shown, in order to prevent the tape from causing discomfort to the patient, fixing columns 14 close to the expansion hole 4 are provided on both sides of the upper end of the lip plate 1.

[0030] During clinical operation, after the endotracheal tube is inserted, the medical staff first presses the clamp head 6 inward to separate the clamping strip 11 from the clamping slot 9, removes the clamp head 6, opens the opening 8, moves the mouthpiece to clamp the endotracheal tube into the expansion hole 4, then clamps the clamp head 6, lets the patient bite the mouthpiece tube 2, and then fixes the endotracheal tube to the fixing column 14 with tape, and then inserts the endoscope into the body through the endoscope port 3.

[0031] It should be noted that the above embodiments are only specific and clear descriptions of the technical solutions and technical features of the present application. For those skilled in the art, solutions or features that belong to the prior art or common knowledge are not described in detail in the above embodiments.

[0032] In addition, the technical solutions of the present application are not limited to the above-mentioned embodiments. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
