[0019] In order to make the purpose, technical scheme and advantages of the embodiments of the present application more clear, the technical scheme in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0020] Please refer to Figures 1 to 4 The present application provides a technical scheme: a dental pulp cavity suction tube structure, comprising a suction tube 1, one end of the suction tube 1 is integrally provided with an adapter 2, the other end of the suction tube 1 is communicated with a universal adjusting joint 3 and is detachably connected with a suction head 4 through the universal adjusting joint 3.

[0021] Please refer to Figure 1 and Figure 2 The suction tube 1 is in overall arc-shaped extension structure, the arc is 55°, the diameters of the two ends of the suction tube 1 are inconsistent, the adapter 2 is arranged at the large-diameter end of the suction tube 1, and the universal adjusting joint 3 is arranged at the small-diameter end of the suction tube 1.

[0022] The suction tube 1 is made into 55° arc-shaped structure, the adapter 2 is integrally arranged at the large-diameter end, so as to be better connected with external equipment; the universal adjusting joint 3 is arranged at the small-diameter end, so that the suction head 4 can more accurately reach the pulp cavity position. The 55° arc design conforms to the structural characteristics of the inside of human oral cavity, can more smoothly drain the liquid in the pulp cavity into the suction tube 1, and improves the suction effect. The design of different diameters of the two ends is convenient for connecting with external equipment of larger caliber at the large-diameter end, and the suction head 4 is more slender at the small-diameter end, so that the suction head 4 can better penetrate into the pulp cavity, and the operation accuracy is improved.

[0023] Further, the suction tube 1 is made of transparent material as a whole.

[0024] In the manufacture of the suction tube 1, a transparent material such as transparent plastic is selected to ensure that the doctor can clearly see the inside of the suction tube 1. The transparent material allows the doctor to observe the color and flow of the liquid in the suction tube 1 in real time, which helps to determine the condition in the medullary cavity, such as whether there is bleeding or infection, so that the treatment plan can be adjusted in a timely manner. The visualization of the operation is improved, the misoperation caused by the inability to observe the internal situation is reduced, and the safety and effectiveness of the treatment are improved.

[0025] Please refer to Figure 3 and Figure 4 , the universal adjusting joint 3 includes a ball shaft sleeve 301, one side surface of the ball shaft sleeve 301 is fixedly connected with the small diameter end surface of the suction tube 1 through a plurality of connecting rods 302 arranged in an annular array, a ball shaft 303 is movably connected inside the ball shaft sleeve 301, a connecting hole 304 is provided through the inner wall of the ball shaft 303, a connecting hose 305 is fixedly connected between the inner walls of the connecting hole 304, one end of the connecting hose 305 is in communication with the small diameter end of the suction tube 1, and the other end of the connecting hose 305 is integrally and communicatively provided with a joint 306. The joint 306 is detachably connected with the suction head 4.

[0026] The ball shaft sleeve 301 is fixedly connected with the small diameter end surface of the suction tube 1 through a plurality of connecting rods 302, and the ball shaft 303 is movably connected inside the ball shaft sleeve 301 and can freely rotate in the ball shaft sleeve 301. The connecting hole 304 penetrates the ball shaft 303, and the connecting hose 305 is fixed between the inner walls of the connecting hole 304, one end of which is in communication with the small diameter end of the suction tube 1, and the other end is connected with the suction head 4 through the joint 306. When the angle of the suction head 4 needs to be adjusted, the ball shaft 303 rotates in the ball shaft sleeve 301, driving the connecting hose 305 and the suction head 4 to rotate together, while the connecting hose 305 can ensure that the suction passage is not affected by the angle adjustment. The universal adjusting function of the suction head 4 is realized, which can meet the suction needs of various complex tooth positions in the oral cavity, greatly improving the flexibility of the operation. Further, the joint 306 is connected with the suction head 4 in interference fit.

[0027] The suction head 4 is a hollow conical structure, and elastic sealing material can be provided on the inner wall of the suction head 4 or the outer wall of the joint 306. The interference fit of the conical inner wall on the end of the joint 306 realizes convenient connection while maintaining certain connection stability and sealing performance of the connection. When the joint 306 is not connected with the suction head 4, it can directly absorb moisture in the space outside the rubber seal, reducing the space occupation and the obstruction of the doctor's view.

[0028] Further, the joint 306 is a double-cone structure as a whole, and the diameter of the middle part is greater than that of the two ends.

[0029] The double-cone structure joint 306 can be more convenient for sleeved connection with the conical suction head 4, can be adapted to more sizes of the conical structure suction head 4, and can also be convenient for guiding the inhaled liquid to the suction pipe 1 through the connecting hose 305, and reduce liquid residues in the joint 306.

[0030] Further, the ball sleeve 301 and the ball shaft 303 are provided with a damping structure.

[0031] The damping structure can adopt various forms, such as setting rubber pads, smearing damping grease and the like on the contact surfaces of the ball sleeve 301 and the ball shaft 303, so as to realize the damping effect by increasing the friction. The damping structure ensures that the suction head 4 can be stably maintained after being adjusted to the required angle, avoids affecting the operation effect due to accidental change of the angle in the suction process, and improves the precision of the operation. The damping structure reduces the trouble of the doctor in the operation process to constantly adjust the angle of the suction head 4, and improves the work efficiency.

[0032] Working principle: The adapter 2 at one end of the suction pipe 1 is connected with an external device, the suction pipe 1 with a 55° arc shape and different diameters at two ends is beneficial for drainage and precise operation, the transparent material is convenient for observing the liquid in the pipe. The ball sleeve 301 of the universal adjusting joint 3 is fixed with the small-diameter end of the suction pipe 1 through the connecting rod 302, the ball shaft 303 rotates in the ball sleeve 301 to drive the suction head 4 to change the angle, and the connecting hose 305 ensures that the suction channel is unobstructed. The suction head 4 is connected with the double-cone joint 306 in interference fit, realizes stable connection and sealing, the double-cone joint 306 is convenient for sleeved connection with the suction head 4 and reduces liquid residues. The damping structure between the ball sleeve 301 and the ball shaft 303 makes the suction head 4 stable after adjusting the angle, thereby helping the doctor to complete the dental pulp cavity liquid suction operation.

[0033] The above only describes the preferred embodiments of the present application and is not used to limit the present application. For those skilled in the art, the present application can have various changes and modifications. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.
