Anesthesia catheter

The invention discloses an anesthesia catheter. The anesthesia catheter comprises a catheter body; the catheter body is provided with a catheter wall; a medicine channel is defined by the catheter wall; the anesthesia catheter further comprises a metal wire; the metal wire is fixedly connected to the interior of the catheter wall; the metal wire is linear and extends in the length direction of thecatheter body; and the tensile strength of the metal wire is smaller than that of the catheter body. The metal wire is linear, and the tensile strength of the metal wire is smaller than that of the catheter body, so that in the process of pulling and taking out the catheter, if the anesthetic catheter is jammed by human bones or knotted in the human body, the resistance is relatively large, if the anesthetic catheter is still pulled by relatively large force, the metal wire is broken earlier than the catheter body, at the moment, a medical staff can obtain relatively large force feedback, namely feel the falling feel
