[0029] Furthermore, the driving assembly includes: a motor 52, a ball screw 53, and a screw nut 54; the motor 52 is arranged at the rear end of the housing 50, and the ball screw 53 is connected to the output shaft of the motor 52; the ball screw 53 is provided with a screw nut 54 on the outer thread sleeve, and the screw nut 54 and the connecting block 572 are connected by an extension rod 541; the front end of the ball screw 53 is connected to a clamping member 55, and the rear end of the push rod 57 is provided with a clamping block 571 matching the clamping member 55, and the clamping member 55 is clamped with the clamping block 571; the outer rotating sleeve of the clamping block 571 is provided with a connecting block 572, and the first support rod 574 is rotatably connected to the connecting block 572; after the motor 52 is turned on, the motor 52 drives The movable ball screw 53 rotates, and the screw nut 54 on the ball screw 53 moves toward the front end. Since the clamping piece 55 is clamped with the clamping block 571 in the initial state, the ball screw 53 drives the push rod 57 to rotate and move forward at the same time. After the push rod 57 moves forward for a distance, the clamping block 571 at the rear end of the push rod 57 is disconnected from the clamping piece 55. At this time, the screw nut 54 will still push the connecting block 572 and the push rod 57 forward under the connection of the extension rod 541, but the push rod 57 will no longer rotate; when the connecting block 572 moves forward, it drives the first support rod 574 to rotate, and the first support rod 574 pushes the upper lip support plate 40 upward to open the patient's upper lip.

[0030] Furthermore, the front end of the syringe 56 is rotatably connected to a syringe cover 58, and a connecting rod 59 is connected between the syringe cover 58 and the housing 50; Figure 6As shown, a spring 564 is provided between the needle 562 and the syringe 56 and they are connected by a hose 563, and the front end of the needle 562 abuts against the syringe cover 58; a through hole 581 is provided on the syringe cover 58, and the through hole 581 is used to penetrate the needle 562; in the initial state, the front end of the needle 562 abuts against the syringe cover 58 and the spring 564 is in a compressed state. After the motor 52 is turned on, the motor 52 drives the ball screw 53 to rotate, and the screw nut 54 on the ball screw 53 moves toward the front end. Since the clamping piece 55 is clamped with the clamping block 571 in the initial state, the ball screw 53 drives the push rod 57 to rotate and move forward at the same time, and the push rod 57 drives the piston 573 connected thereto to rotate and move forward at the same time. When the piston 573 rotates, it drives the syringe 56 to rotate through the clamping groove 561, and the rotation of the syringe 56 drives The needle 562 rotates until the needle 562 reaches the through hole 581, at which time the spring 564 is no longer compressed and rebounds forward, driving the needle 562 to puncture forward from the through hole 581; at the same time, the push rod 57 has moved forward a distance, and the clamping block 571 at the rear end of the push rod 57 is disconnected from the clamping piece 55, the motor 52 continues to rotate, and the screw nut 54 will still push the connecting block 572 and the push rod 57 forward under the connection of the extension rod 541. At this time, the syringe 56 does not move, and only the push rod 57 and the front end piston 573 move forward to administer the drug; after the syringe cover 58 is in contact with the affected area, the motor 52 is turned on, which can not only achieve stable puncture of the needle 562 and relieve the patient's pain, but also immediately perform stable drug administration after the needle 562 punctures, thereby improving the accuracy of the injection volume and saving medical manpower.

[0031] Furthermore, if Figure 8 As shown, the drainage assembly includes: a drainage tube 60, a flow regulator 63 and a slider 64; the flow regulator 63 is a trapezoidal block with a hollow middle; the drainage tube 60 runs through the flow regulator 63, and a micro pump is arranged at one end of the drainage tube 60 away from the fixed sleeve 10 to provide suction; the top of the flow regulator 63 is an inclined structure, and the slider 64 is connected to the flow regulator 63 by sliding along the inclined direction of the flow regulator 63. When the slider 64 slides forward, the extrusion of the drainage tube 60 is reduced and the flow rate is increased; one end of the slider 64 is rotatably connected to the second support rod 66, and the other end is connected to the connecting block 572 through a connecting rod 65; the connecting rod 65 is The telescopic rod structure ensures that the slider 64 can remain connected to the connecting block 572 during the sliding process. Through the linkage setting, after the motor 52 is turned on, the drug delivery component performs puncture and drug delivery, wherein the forward movement of the connecting block 572 drives the connecting rod 65 to move forward, and the connecting rod 65 drives the slider 64 to slide forward. At this time, the squeezing effect of the slider 64 on the drainage tube 60 is reduced, and the drainage tube 60 increases the flow rate. Under the action of the micro pump, the drainage tube 60 attracts the patient's saliva and residual medicine and discharges them, and the second support rod 66 at one end of the slider 64 rotates to support the lower lip support plate 30 downward, thereby achieving the goal of supporting the patient's lower lip. Example 2

[0032] According to Example 1, Figure 1 , Figure 8 and Fig. 9 As shown, in order to further discharge the secreted saliva and residual medicine in the patient's mouth, the front end of the drainage tube 60 is further provided with a first branch tube 61 and a second branch tube 62; the front end of the first branch tube 61 is connected to a tongue depressor 70, and the bottom and side of the tongue depressor 70 are provided with water-washing cotton to absorb the patient's saliva, which is connected and diverted out by the first branch tube 61 and the drainage tube 60; the second branch tube 62 is placed on the inner side of the lower teeth to attract the saliva and residual medicine on the inner side of the lower teeth; an upper jaw plate 71 is provided above the tongue depressor 70, and an electric push rod 72 is connected between the tongue depressor 70 and the upper jaw plate 71, and the electric push rod 72 drives the tongue depressor 70 and the upper jaw plate 71 to push open the mouth, so as to facilitate the observation of the internal condition of the patient's mouth.

[0033] The operation method of the oral dental pulp treatment auxiliary sleeve provided in the present invention is as follows: After fixing the fixing sleeve 10 to the patient's chin, the lower lip support plate 30 and the upper lip support plate 40 are respectively fitted to the lower lip and upper lip of the patient, at which time the lower lip baffle 32 and the upper lip baffle 41 cover the lips; then the tongue depressor 70 is placed on the patient's tongue, and the electric push rod 72 is turned on. The electric push rod 72 drives the tongue depressor 70 and the upper palate plate 71 to push open the oral cavity, so as to facilitate observation of the internal condition of the patient's oral cavity; then, after the syringe cover 58 contacts the affected area, the motor 52 is turned on, and the motor 52 drives the ball screw 53 to rotate, and the screw nut 54 on the ball screw 53 moves toward the front end. The lower clamping member 55 is clamped with the clamping block 571, so the ball screw 53 drives the push rod 57 to rotate and move forward, and the push rod 57 drives the piston 573 connected thereto to rotate and move forward. When the piston 573 rotates, it drives the syringe 56 to rotate through the clamping groove 561, and the rotation of the syringe 56 drives the needle 562 to rotate until the needle 562 reaches the through hole 581. At this time, the spring 564 is no longer compressed and rebounds forward, driving the needle 562 to puncture the affected area through the through hole 581; at the same time, the forward movement of the connecting block 572 drives the first support 562 to rotate. The rod 574 rotates, and the first support rod 574 pushes the upper lip support plate 40 upward to open the patient's upper lip. The forward movement of the connecting block 572 drives the connecting rod 65 to move forward, and the connecting rod 65 drives the slider 64 to slide forward. At this time, the extrusion effect of the slider 64 on the drainage tube 60 is reduced, and the drainage tube 60 increases the flow rate. Under the action of the micro pump, the first branch pipe 61 and the second branch pipe 62 respectively suck the saliva and the residual liquid medicine on the inner side of the upper and lower teeth of the tongue depressor 70, and the saliva and the residual liquid medicine are drained outward from the drainage tube 60. At the same time, the slider 64 at one end The second support rod 66 rotates to push the lower lip support plate 30 downward, thereby pushing the patient's lower lip open, making it easier for medical staff to operate and observe; when the needle 562 pierces forward from the through hole 581 into the affected area, the push rod 57 has moved forward a certain distance, and the clamping block 571 at the rear end of the push rod 57 is disconnected from the clamping piece 55, the motor 52 continues to rotate, and the screw nut 54 will still push the connecting block 572 and the push rod 57 forward under the connection of the extension rod 541. At this time, the syringe 56 does not move, only the push rod 57 and the piston 573 at the front end move forward for stable drug administration.
