Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a device for endodontic treatment in oral medicine. Background Art

[0002] The function of the dental pulp tissue is to form dentin, and it has the ability of nutrition, sensation, and defense. The dental pulp nerves are particularly sensitive to external stimuli and can produce unbearable severe pain. The dental pulp undergoes different pathological changes due to the different effects of pathogenic stimuli and differences in the body's resistance. Root canal therapy is the most commonly used and effective treatment method for pulp disease and periapical disease in the world. The principle of root canal therapy is to remove most of the infected substances in the root canal by mechanical and chemical methods, and to prevent periapical lesions or promote the healing of periapical lesions that have already occurred by filling the root canal and sealing the crown.

[0003] After searching, the patent document with publication number: CN215839657U discloses a device for oral endodontic treatment, which belongs to the field of medical devices and includes a syringe barrel and a connecting pipe. A piston push rod is slidably connected to one side of the syringe barrel, one end of the piston push rod is embedded and plugged into the surface of the piston, the piston is arranged inside the syringe barrel, and the other end of the piston push rod is integrally formed with a push plate. The connecting pipe and the sleeve are integrally plugged into the protective shell, and the sleeve is screwed and fixed with the internal thread arranged on the inner wall of the protective shell through the external thread. The end of the connecting pipe is connected to the water outlet, and the other end of the connecting pipe is equipped with a needle. The utility model optimizes the structure of the oral endodontic treatment device and utilizes the shape of the connecting pipe to make the device body convenient for injection work on deeper gums and easy to disassemble and maintain at any time.

[0004] Although the above patent solution solves the shortcomings of traditional devices for oral endodontic treatment, the solution still has some shortcomings. When the drug used for treatment is pushed through the syringe barrel, piston push rod, piston and push plate, when the piston and the inner wall of the syringe barrel change from static friction to sliding friction, it is easy to push too much or push too little drug, and the accuracy of the amount of pushed drug is poor. In addition, due to the limitation of the angle of the oral cavity or teeth, the connecting pipe and the needle cannot be adjusted in time. Therefore, we propose a device for oral endodontic treatment to solve the above problems. Utility Model Content
