[0022] The technical solution of the utility model is further specifically described below through examples and in conjunction with the accompanying drawings. In the specification, the same or similar reference numerals indicate the same or similar components. The following description of the implementation mode of the utility model with reference to the accompanying drawings is intended to explain the overall inventive concept of the utility model and should not be construed as a limitation of the utility model.

[0023] In addition, in the detailed description below, for ease of explanation, many specific details are set forth to provide a comprehensive understanding of the disclosed embodiments. However, it is apparent that one or more embodiments may be implemented without these specific details. In other cases, known structures and devices are embodied in a schematic manner to simplify the accompanying drawings.

[0024] The inventors have found that in order to prevent the articulator from sliding into the throat during the examination, the outer baffle of the existing two-in-one articulator structure (articulator and ventilation tube two-in-one structure) is usually set larger, but the larger outer baffle greatly blocks the doctor's line of sight, greatly increasing the difficulty of the doctor's operation of the articulator. In some other two-in-one articulator structures, the ventilation tube is made of hard material, which is easy to accidentally injure the patient's throat, increasing the risk of medical operation.

[0025] In view of this, the inventor creatively proposed an endoscope bite with airway protection and an endoscope system, which can solve the problem of combining bite and ventilation in one and protect the patient's airway.

[0026] According to an overall inventive concept of the utility model, an endoscope bite with an airway is characterized in that it includes: a bite portion and a ventilation tube portion, wherein the bite portion includes an outer baffle and a hollow tube, the outer baffle is an arc-shaped plate bent toward the distal direction, a ventilation tube opening is formed in the center of the outer baffle, and the hollow tube is extended from the ventilation tube opening toward the distal direction; the ventilation tube portion includes a hose, a metal wire and a connecting port, the hose is a hollow tube with openings at both ends, the metal wire is wrapped around the outer circumference of the hose, the connecting port is arranged at the proximal end of the hose, and is extended radially outward from the outer circumference of the hose; the ventilation tube portion can be inserted into the hollow tube and moved therein until it extends out of the ventilation tube opening, and the connecting port is detachably connected to the outer baffle.

[0027] like Figures 1 to 5 As shown, the endoscope mouthpiece 100 with airway in the embodiment of the present invention comprises a mouthpiece portion 110 and a vent portion 120. The vent portion 120 can be inserted into the mouthpiece portion 110 for connection. It should be noted that in the embodiment of the present invention, the "proximal end" refers to the end close to the operator, and the "distal end" refers to the end close to the target position in the body.

[0028] The bite portion 110 of the embodiment of the utility model includes an outer baffle 111 and a hollow cylinder 112. The baffle 111 is an arc-shaped plate bent toward the distal end, and the arc-shaped plate can be easily fitted with the shape of the patient's mouth. A vent opening 113 is formed in the center of the outer baffle, and the hollow cylinder 112 extends from the vent opening 113 toward the distal end. Therefore, the bite portion 110 is generally T-shaped.

[0029] In some preferred embodiments, a protrusion is formed at the distal end of the hollow cylinder 112 .

[0030] In some preferred embodiments, the two sides of the outer baffle 111 or the left and right sides of the vent opening 113 respectively form a strap opening 114. The strap opening can be connected to a strap (not shown), and after the strap is connected, the strap can be wrapped around the patient's head and connected to each other, so that the mouthpiece of the utility model embodiment is connected to the patient's head.

[0031] The ventilation tube portion 120 of the embodiment of the utility model includes a hose 121, a metal wire 122 and a connection port 123. The hose 121 is a hollow tube with openings at both ends, that is, a channel is formed therein, and the insertion portion of the endoscope can be inserted and moved therein. The metal wire 122 is wrapped around the outer circumference of the hose 121. The connection port 123 is arranged at the proximal end of the hose 121, and is formed by extending radially outward from the outer circumference of the hose 121, that is, finally forming a boss structure. The structure of the metal wire 122 wrapped around the ventilation tube portion 120 allows the ventilation tube portion 120 to have a certain rigidity while maintaining flexibility.

[0032] In the embodiment of the present invention, the vent pipe portion 120 can be inserted into the hollow cylinder 112 of the bite portion 110 and move therein until it extends out of the vent pipe opening 113. The connection opening 123 of the vent pipe portion 120 is detachably connected to the outer baffle 111.

[0033] In some preferred embodiments, buckle grooves 115 are respectively provided on both sides of the vent opening 113, that is, a total of two buckles 124 are provided on the bite portion 110. Buckles 124 are provided on both sides of the connection port 123 toward the distal direction, and the buckles 124 are of a special-shaped structure with a barb structure. Specifically, the connection port 123 is provided with a first pair of sides 1231, a second pair of sides 1232, a third pair of sides 1233, a fourth pair of sides 1234 and a fifth pair of sides 1235. The first pair of sides 1231 and the second pair of sides 1232 are arranged in parallel, the third pair of sides 1233 is extended from the distal end of the first pair of sides 1231 in a direction of a certain angle, the fourth pair of sides 1234 is extended from the distal end of the second pair of sides 1232 in a vertical direction, and the fifth pair of sides 1235 is extended from the distal end of the fourth pair of sides 1234 to the distal end of the third pair of sides 1233. The buckle 124 can be connected to the buckle groove 115. The third pair of sides 1233 are buckle guide inclined surfaces, and the fourth pair of sides 1234 are buckle stop surfaces. When connected, the buckle 124 extends into the buckle groove 115. Since the buckle 124 is made of polymer material, it will be squeezed when moving in the buckle groove 115. When it moves to a point where there is no buckle groove 115 squeezing, it is released under the elasticity of the polymer material itself, and is buckled on the inner stop surface 116 of the outer baffle 111.

[0034] In some preferred embodiments, the hose 121 is made of a polymer material, which can protect the airway and esophagus to avoid accidental injury, thus meeting clinical use requirements.

[0035] In some preferred embodiments, the hose 121 and the metal wire 122 are formed by composite extrusion, that is, two different materials are extruded together.

[0036] In some preferred embodiments, the distal end of the hose 121 of the ventilating tube portion 120 is an oblique opening. Preferably, the oblique opening can be formed by mechanical cutting.

[0037] In some preferred embodiments, the buckle 124 is made of polymer material.

[0038] The endoscope system provided by the embodiment of the utility model comprises an endoscope and the aforementioned endoscope mouthpiece 100 with airway protection, wherein the insertion portion of the endoscope can enter the human body from the ventilation tube port 113 of the endoscope mouthpiece 100 and the opening of the hose 121 at the distal end.

[0039] The embodiment of the utility model provides an endoscope bite with airway protection. After the bite portion is fixed on the teeth, the ventilation tube portion moves downward toward the throat along with the endoscope. The ventilation tube portion can be driven by adjusting the direction of the endoscope. The ventilation tube portion made of polymer material can protect the airway and esophagus to meet clinical usage requirements.
