Description

Technical Field

[0001] The present invention relates to the technical field of root canal treatment, and specifically to a bracket for root canal treatment. Background Art

[0002] Root canal treatment is a common dental procedure used to treat teeth with pulp infection or necrosis. The dental pulp is located inside the tooth and contains nerves and blood vessels. When the dental pulp is infected by bacteria or physically damaged, it can cause severe pain or even abscess. Root canal treatment aims to preserve the affected tooth by removing the infected pulp tissue, cleaning and filling the root canal, thus avoiding tooth extraction. The treatment process generally consists of several steps: First, the dentist will perform local anesthesia on the affected tooth to ensure that the patient feels no pain during the treatment. Then, a small hole is drilled at the top of the tooth to access the pulp chamber. Specialized instruments are used to remove the infected pulp tissue and thoroughly clean the root canal. Subsequently, the root canal is disinfected and filled with biocompatible materials to prevent bacteria from invading again. Finally, a dental crown is usually installed on the tooth to restore its function and appearance.

[0003] The bracket for root canal treatment is mainly used in dental treatment to fix and support root canal treatment equipment, aiming to improve the accuracy and efficiency of the operation. However, the bracket itself does not have the function of cleaning water droplets and disinfectant solution on the outer surface of the root canal treatment equipment. During root canal treatment, the outer surface of the equipment may be contaminated with water droplets, disinfectant solution or other liquid residues. If these residues are not cleaned in time, they may affect the normal use of the equipment and even increase the risk of cross-infection. Summary of the Invention

A connecting column 656 is fixedly connected to the outer surface of the intake box 62. The end of the connecting column 656 is fixedly connected to a sealing box 657. The end of the first connecting pipe 277 is fixedly connected to the lower surface of the sealing box 657. A piston plate 658 is slidably connected to the inner cavity of the sealing box 657. The upper surface of the piston plate 658 is fixedly connected to a fourth support frame 659, and the top of the fourth support frame 659 is fixedly connected to the surface of the jet port 655. By providing the exhaust mechanism 65,When the clamping mechanism 2 is moved upward by medical staff on the outer surface of the dental chair, the opening at the bottom of the air inlet box 62 can be blocked, so that the air flow flows to the exhaust box 66. By setting the first blocking plate 652 and the second blocking plate 654, the opening at the bottom of the air inlet box 62 can be blocked when they come into contact with each other. By setting the sealing box 657 and the piston plate 658, when the air flow enters the inner cavity of the sealing box 657 through the first connecting pipe 277, the internal air pressure can be increased, so that the piston plate 658 drives the jet port 655 to move upward.,

[0051] Working principle: During use, during the installation of the device, the operator wraps the two wrapping mechanisms 27 around the outer surface of the dental chair, then pulls the clamping plate 23 to move the clamping plate 23 upward, and then makes the clamping frame 25 enter the inner cavity of the clamping rack 21. Then, the clamping plate 23 is released. Under the influence of the elastic potential energy of the first spring 24, the clamping plate 23 deeply inserts into the inner cavities of the clamping rack 21 and the clamping frame 25, so that the two wrapping mechanisms 27 are in close contact with the outer surface of the dental chair. Under the action of gravity, the device will tend to move downward. During this process, under the influence of friction and the elastic potential energy of the second spring 2714, the roller 2711 is always subjected to a force upward along the track ring 279, so that the roller 2711 squeezes the outer surface of the dental chair, thus ensuring that the device will not slide downward on the outer surface of the dental chair;

[0052] During root canal treatment, the operator connects the fan 64 to the power supply and turns on the switch, so that an air flow is generated in the inner cavities of the air inlet box 62 and the connecting frame 4, and the air flow is discharged from the jet port 655. After the root canal treatment equipment is used, it is disinfected and placed in the inner cavities of the positioning frame 54 and the bottom frame 51. Under the influence of the air flow, the water absorption frame 59 and the water permeable plate 510 generate suction, so that the residual water droplets or disinfectant residues on the outer surface of the root canal treatment equipment are sucked into the inner cavity of the air inlet box 62 and finally sprayed out from the jet port 655;

[0053] During the operation, when it is necessary to move the clamping mechanism 2 upward on the outer surface of the dental chair, the roller 2711 will move downward, so that the extrusion strip 2715 extrudes the first telescopic box 276. During this process, the internal air enters the inner cavity of the sealing box 657 through the first connecting pipe 277, so that the piston plate 658 drives the jet port 655 to move upward, and makes the first blocking plate 652 and the second blocking plate 654 come into close contact with each other, so that the air in the inner cavity of the air inlet box 62 can only be discharged from the exhaust box 66, and the second telescopic box 56 expands, and finally the extrusion plate 57 clamps the root canal treatment equipment, achieving the effect of preventing the equipment from falling off.
