Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a dental pulp anesthesia device. Background Art

[0002] In the treatment of endodontics, surgery is often required to solve problems such as root canal treatment and pulpectomy. These surgeries are usually accompanied by significant pain. Therefore, anesthesia plays a vital role in such surgeries.

[0003] The main safety issue of traditional dental anesthesia devices is that they may be improperly reused. Since the design of the equipment may not include sufficient safety protection measures, such as disposable mechanisms or locking systems, some anesthesia devices or their components, especially needles, are at risk of being reused. Reusing anesthesia device parts, especially needles, may not only lead to cross-infection, including the spread of viruses and bacteria, but may also affect the accurate delivery of anesthetic agents because used needles may be clogged or worn. In addition, traditional anesthesia devices usually lack lighting equipment, which is particularly inconvenient during treatment because dental surgery often needs to be performed in a small space in the mouth. The lack of sufficient light makes it difficult for doctors to operate accurately, increasing the difficulty and risk of the operation. These shortcomings have prompted medical device developers to seek more advanced solutions to improve the safety of dental anesthesia and the accuracy of surgery. Utility Model Content
