Technical Field

[0001] The utility model relates to a separating and collecting device for the reusable syringe needle in stomatology which is convenient for disinfection, and belongs to the technical field of oral medicine. Background Technique

[0002] The local anesthetic syringe for oral cavity is a device for administering anesthetic drugs, and is currently widely used in tooth extraction techniques, dental implant techniques, periodontal treatment operations, etc., and is very widely used in oral specialties. It generally includes a syringe body, a needle and a piston. In medical procedures, anesthetic syringes are used to accurately inject anesthetic drugs into the patient's body to achieve the purpose of anesthesia.

[0003] At present, after the oral anesthetic syringe is used, there are two safety hazards, including being prone to cause sharp injuries, resulting in iatrogenic occupational exposure and increasing the risk of nosocomial infection; the specific manifestations are as follows:

[0004] First: After the syringe is used, the needle cap needs to be put back, and there is a risk of stabbing during the return process of putting the cap back.

[0005] Second: When cleaning and disinfecting, the needle needs to be removed from the anesthetic syringe and placed in a sharp container. At present, generally two methods are adopted for removing the needle clinically. One is to rotate it off by hand, which is also prone to cause sharp injuries; the second is to hold the needle with a needle holder and break it off, but this method is likely to damage the precision of the needle holder.

[0006] In order to solve the above problems, it is particularly important to develop a device that does not require putting the cap back, and at the same time can simply remove the needle without touching it by hand or using instruments. Content of the Utility Model
