[0002] Local anesthesia refers to applying local anesthetic to a local part of the body while the patient is conscious, so that the sensory nerve conduction function of a certain part of the body is temporarily blocked, and the motor nerve conduction remains intact or is blocked to varying degrees at the same time. Currently, in various consulting rooms of the stomatology department, when treating, repairing, plastic surgery and performing small surgical operations on patients, local anesthesia is often required. Most of the current anesthetic syringes are boosters that can push the anesthetic at a constant speed, which brings convenience to doctors and reduces the pain of patients to a certain extent.
