The anesthetic needle vertical puncture device is a device used to vertically puncture the designated site of surgical anesthesia with an anesthetic needle.
[0003] Because when performing anesthesia puncture, it is necessary to ensure a vertical angle to achieve the best anesthesia effect. However, due to the long puncture needle, when medical staff perform vertical puncture on patients, it is easy for the operator's nervousness to cause the needle tube to be misaligned with the part to be punctured, resulting in a deviation in the injection angle of the anesthesia needle and a reduction in the anesthesia effect. In addition, the needle tube itself is not stable during the process of holding the needle tube to puncture the patient's body, and then the medical staff needs to use the needle tube to puncture the patient's body again, which can easily increase the mental burden of the medical staff.
