[0036] The pushing assembly includes a fixed box 209, an electric actuator 210, a second ring 211, a connecting rod 212, a slide plate 213, a second elastic member 214 and a baffle 215; the front part of the outer wall of the adsorption cylinder 206 is fixedly connected with the fixed box 209; the inner wall of the fixed box 209 is fixedly connected with the electric actuator 210; the telescopic part of the electric actuator 210 is fixedly connected with the second ring 211, and the second ring 211 is located on the outer side of the suction cup 208. The movement of the second ring 211 squeezes the arc portion 20801, thereby causing the suction cup 208 to deform and shrink inward, and squeezes all the push rods 218 through the inner wall of the suction cup 208, so that all the push rods 218 gather toward the center position of the suction cup 208. , thereby reducing the diameter of the suction cup 208 and changing the direction of all the push rods 218; the outer wall of the second ring 211 is fixedly connected to two connecting rods 212 distributed up and down; the left part of the adsorption cylinder 206 is slidably connected to two slides 213 distributed up and down; the right side of each slide 213 is fixedly connected to a second elastic member 214; the other ends of the two second elastic members 214 are respectively fixedly connected to a connecting rod 212; the left side of each slide 213 and the right side of the slide 213 are respectively fixedly connected to a baffle 215, and the baffle 215 is set to an elastic material; the ends of all the baffles 215 away from the slide 213 are fixedly connected to the adsorption cylinder 206; the two slides 213 are commonly fixedly connected to the first support ring 216.

[0037] An arc-shaped portion 20801 is provided in the middle of the suction cup 208 for cooperating with the second ring 211 to move.

[0038] The first elastic member 202 is a spring rod, the second elastic member 214 is a spring, and the electric actuator 210 is an electric push rod.

[0039] During adsorption: the handle 101 and the catheter 3 are manually held, and the external suction pump is pre-connected to the fixed tube 1 and the collecting tube 5, and then the external air pump is connected to the airbag 204, and then the suction cup 208 is inserted into the patient's mouth, and the patient is guided to bite the ring sleeve 203 with his teeth. At this time, the airbag 204 is located on the outside of the lips, and then the external air pump is controlled to operate to inflate the airbag 204, thereby isolating the oral cavity from the external air, so that a closed space is formed in the oral cavity to facilitate later adsorption, effectively improving the adsorption efficiency and adsorption effect. During the adsorption process, when a large amount of foreign matter flows out of the oral cavity, the existing adsorption device cannot quickly remove all the foreign matter, and when the foreign matter is viscous and adheres to the inner wall of the oral cavity, it is necessary to increase the strength of adsorption to remove the foreign matter, which increases the patient's discomfort and affects the smooth progress of the operation. At this time, the camera 205 is located in the patient's oral cavity, and the foreign matter accumulation is detected by the camera 205, and then manually adjusted The directions of the fixed cylinder 1 and the cylinder 2 are driven to rotate, thereby driving all the connected parts to change the direction of the suction cup 208, thereby realizing multi-angle adjustment, so as to achieve the purpose of quickly sucking out foreign matter in the oral cavity. Next, the electric actuator 210 is controlled to start and drive the second ring 211 to move to the left. The movement of the second ring 211 squeezes the arc portion 20801, thereby causing the suction cup 208 to deform and shrink inward, and squeezes all the ejector rods 218 through the inner wall of the suction cup 208, so that all the ejector rods 218 gather toward the center of the suction cup 208, thereby reducing the diameter of the suction cup 208 and changing the direction of all the ejector rods 218. At this time, the external suction pump is controlled to operate, thereby generating negative pressure in the cylinder 2, the adsorption cylinder 206 and the suction cup 208, thereby sucking out a large amount of foreign matter from the oral cavity through the suction cup 208, effectively avoiding the problem of foreign matter adhering to the inner wall of the oral cavity, and improving the adsorption efficiency by changing the diameter of the suction cup 208.

[0040] And when the second circular ring 211 moves to the left to squeeze the arc-shaped portion 20801, the second circular ring 211 moves to drive the two connecting rods 212 to move, thereby compressing the two second elastic members 214. When the two second elastic members 214 are compressed to the limit, the second circular ring 211 will continue to move to the left, and then drive the corresponding slide plate 213 to move to the left through the corresponding connecting rod 212 and the corresponding second elastic member 214, thereby stretching the corresponding baffle plate 215. Since the baffle plates 215 are all made of elastic material, the adsorption cylinder 206 is always in a closed state, so as to form a negative pressure in the adsorption cylinder 206.

At this time, the arc portion 20801 no longer squeezes all the top rods 218, so that all the top rods 218 are reset by their own elastic force, and then all the top rods 218 expand outward, thereby dispersing the more viscous oral foreign matter, and then the external suction pump is operated to generate negative pressure in the cylinder 2, the adsorption cylinder 206 and the suction cup 208, so that the dispersed viscous state is sucked out, and the problem of large-scale accumulation of foreign matter affecting the adsorption efficiency is avoided.

[0041] Embodiment 2:

[0043] The front and rear ends of the lever 304 are both provided with downward protrusions for moving foreign matter away to prevent the foreign matter from adhering to the inner wall of the adsorption cylinder 206 .

[0044] During quick removal: since foreign matter in the oral cavity is relatively viscous, it is very easy for the foreign matter to adhere to the inner wall of the adsorption cylinder 206 during the suction process, making it difficult to quickly discharge it. When negative pressure is generated in the adsorption cylinder 206, the airflow will flow from left to right, and the flowing airflow will blow all the first baffles 302, thereby causing all the first baffles 302 to rotate, thereby driving the retaining ring 301 to rotate, and the rotation of the retaining ring 301 drives the connecting block 303 to rotate, and the rotation of the connecting block 303 drives all the levers 304 to rotate along the inner wall of the adsorption cylinder 206, and then the levers 304 are used to rotate and move the oral foreign matter adhered to the inner wall of the adsorption cylinder 206, thereby preventing the oral foreign matter from adhering to the inner wall of the adsorption cylinder 206, and then the negative pressure generated in the adsorption cylinder 206 is used to remove the oral foreign matter, thereby achieving rapid discharge of the oral foreign matter.

[0045] Embodiment three:

[0047] During filtration: In order to ensure the normal adsorption operation, a filter screen 405 needs to be arranged in the cylinder 2. However, the filter screen 405 is very easy to be clogged during use, which affects the normal adsorption operation, and further affects the normal operation of oral surgery, and seriously reduces the adsorption efficiency. When the filter screen 405 is clogged, the motor 402 is controlled to start, and the output shaft of the motor 402 rotates to drive the retaining ring 404 to rotate through the transmission shaft 403. At this time, the retaining ring 404 rotates 180 degrees, and further drives all the connected parts to rotate 180 degrees, so that the second support ring 406, the swing rod 407 and the second retaining plate 408 are located on the left side of the filter screen 405. During cleaning, the external pump is controlled to operate so that negative pressure is generated in the collection cylinder 5. At the same time, the solenoid valve 4 is controlled to operate so that the conduit 3 remains unobstructed, thereby generating negative pressure in the cylinder 2, the conduit 3 and the collection cylinder 5. Since negative pressure is generated in the cylinder 2, and And the gas flows from left to right, so that the gas blows all the second baffles 408 when flowing to the right, and then through all the second baffles 408, the corresponding swing rods 407 are changed from the initial vertical hanging state to the horizontal state, so that the end of the swing rod 407 away from the second support ring 406 penetrates into the mesh of the filter 405, so that the filter 405 is dredged by the swing rod 407, and the intermittent operation of the external pump is controlled. When the cylinder 2 no longer inhales, all the swing rods 407 will automatically fall down and return to their original state, so that all the swing rods 407 swing back and forth, so that the filter 405 vibrates, so that the foreign matter on the filter 405 is further shaken off by the vibration, and finally the foreign matter is collected in the collection tube 5, so as to effectively avoid the filter 405 from being easily blocked during use, improve the adsorption efficiency while avoiding affecting the normal operation of oral surgery.
