Description

TECHNICAL FIELD

[0001] The utility model relates to medical instrument technical field especially, it is a kind of mouthpiece for gastroscope with adjustable caliber and has buffering function. BACKGROUND

[0002] The effect of mouthpiece for gastroenterology is mainly to maintain the open state of the patient's oral cavity during gastroscopy, to provide gastroscopy for the patient.

[0003] The existing mouthpiece is usually fixed size, fixed diameter, and needs to first prop open the patient's teeth when placing the mouthpiece, protect the scope body from tooth friction, and reserve operation space for endoscope operator. Since the scope body needs to pass through the middle of the mouthpiece, the fixed-size mouthpiece is usually larger. Placing the mouthpiece in the patient's mouth requires the patient to cooperate with opening the mouth, and then placing the mouthpiece. Due to the size limitation of the mouthpiece, it is difficult to choose the appropriate size of the mouthpiece. At the same time, the mouthpiece circulating on the market is usually a hard plastic device. If the patient's cooperation is not good or the operator applies excessive force by mistake, the teeth in contact with the mouthpiece may be damaged. Therefore, how to design a gastroscope mouthpiece device with adjustable caliber and tooth buffering function is very important in clinical practice and has a wide application prospect. SUMMARY

[0004] To solve the problems mentioned in the background art, the purpose of the utility model is to provide a mouthpiece for gastroscope with adjustable caliber and buffering function.

DETAILED DESCRIPTION

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0016] like Figs. 1-2 As shown, a mouthpiece for gastroscopy with adjustable diameter and buffer function includes a connecting plate 1, an upper arc-shaped piece 2, a lower arc-shaped piece 3, an upper silicone pad 4, a lower silicone pad 5, an upper strap 21, and a lower strap 31. Both the upper arc-shaped piece 2 and the lower arc-shaped piece 3 are V-shaped. The first ends of the upper arc-shaped piece 2 and the lower arc-shaped piece 3 are respectively hinged to the upper and lower sides of the connecting plate 1. The sections of the upper arc-shaped piece 2 and the lower arc-shaped piece 3 away from the connecting plate 1 can be joined together. The length of the section of the lower arc-shaped piece 3 away from the connecting plate 1 is greater than the length of the section of the upper arc-shaped piece 2 away from the connecting plate 1, thus forming a tongue depressor. The opposite sides of the upper arc-shaped piece 2 and the lower arc-shaped piece 3 are respectively connected to an upper... Silicone pad 4 and lower silicone pad 5, upper arc-shaped piece 2 and lower arc-shaped piece 3 are respectively connected to the opposite sides of the connecting plate 1 and the end of the connecting plate 1 with upper cable tie 21 and lower cable tie 31 respectively. The upper and lower sides of the connecting plate 1 are respectively provided with upper fixing hole 11 and lower fixing hole 12 to fix the upper cable tie 21 and lower cable tie 31. The connecting plate 1 is provided with a mirror body through hole 13 at the position between the upper arc-shaped piece 2 and lower arc-shaped piece 3. Upper teeth 22 and lower teeth 32 are respectively provided on the opposite surfaces of the upper arc-shaped piece 2 and lower arc-shaped piece 3. When the upper arc-shaped piece 2 and lower arc-shaped piece 3 are attached together at the ends away from the connecting plate 1, the upper teeth 22 and lower teeth 32 are spaced apart.

[0017] In actual use, the upper arc-shaped piece 2 and the lower arc-shaped piece 3, with the sections furthest from the connecting plate 1, are first attached together. The mouthpiece can be easily inserted from the patient's natural open mouth position, even if the patient is under anesthesia or unconscious. After insertion, the conical mouth opener 6 is placed between the upper arc-shaped piece 2 and the lower arc-shaped piece 3. The conical mouth opener 6 is rotated to a suitable angle to open the upper arc-shaped piece 2 and the lower arc-shaped piece 3. At this point, the section of the lower arc-shaped piece 3 furthest from the connecting plate 1 can hold the tongue down. Simultaneously, the upper strap 21 and the lower strap 31 are passed through the upper fixing hole 11 and the lower fixing hole 12 respectively and tightened. Then, the endoscope is inserted through the appropriate opening created by the mouth opener to complete the examination. The upper silicone pad 4 and the lower silicone pad 5 cushion the teeth, reducing direct contact between the teeth and the hard plastic cushioning pad, thus minimizing damage to the patient's teeth.

[0018] In the embodiment, the upper protrusion 23 is arranged on the end of the upper arc-shaped sheet 2 away from the connecting plate 1 and faces away from the lower arc-shaped sheet 3, and the lower protrusion 33 is arranged on the position corresponding to the upper protrusion 23 of the lower arc-shaped sheet 3 and faces away from the upper arc-shaped sheet 2, so that the upper protrusion 23 and the lower protrusion 33 can be used to clamp the teeth of the patient and prevent the mouth guard from falling off.

[0019] In the embodiment, the upper silica gel pad 4 covers the surface of the upper protrusion 23, and the lower silica gel pad 5 covers the surface of the lower protrusion 33, so that the damage to the teeth can be reduced.

[0020] In the embodiment, when the upper arc-shaped sheet 2 and the lower arc-shaped sheet 3 are attached together away from the connecting plate 1, the part of the lower arc-shaped sheet 3 beyond the upper arc-shaped sheet 2 is arranged obliquely downward, so that the tongue of the patient can be pressed better.

[0021] The above merely describes the preferred embodiments of the utility model and is not used to limit the utility model, and any modification, equivalent replacement, improvement, etc. within the spirit and principle of the utility model should be included in the protection scope of the utility model.
