Technical Field
[0001] The utility model relates to the technical field of treatment needles, and more specifically to a tooth root canal treatment needle that can be prevented from being accidentally swallowed. Background Art
[0002] A root canal needle is a specialized dental instrument used during root canal therapy, primarily for cleaning, unclogging, and preparing the root canal system of a tooth. It is usually made of stainless steel or other medical metal materials, and is designed in different sizes and shapes to accommodate the size and shape of different root canals. Root canal therapy is a method of treating pulp disease and periapical periodontitis, and the process involves cleaning necrotic pulp, disinfecting the root canal, and filling the root canal. Root canal needles play a key role in the cleaning phase, being able to penetrate deep into the root canal, remove necrotic tissue and residue, and ensure thorough cleaning of the root canal. This helps eliminate the source of infection and lays the foundation for subsequent disinfection and filling steps.
[0003] When using a root canal needle, the dentist needs to be careful to ensure that no damage is caused to the teeth and surrounding tissues. The dentist will select the appropriate root canal needle for the operation based on the patient's specific situation and the characteristics of the root canal system. At the same time, the patient also needs to undergo a full oral examination and evaluation before treatment to ensure the safety and effectiveness of root canal treatment.
[0004] At present, during the clinical use of existing root canals, sometimes the indwelling needle is accidentally dropped into the patient's mouth during work. If the patient happens to inhale, the indwelling needle is easily sucked into the throat, causing accidental swallowing. The danger is relatively high, and it is inconvenient to avoid this hidden risk and to ensure the safety of the patient.
