Zusammenfassung:	The utility model relates to a porous hard film external guide pipe, belonging to the technical field of medical appliances. The utility model is formed by that a plurality of medicine guiding holes are arranged within the range of the depth of the effective anesthesia insertion of the hard film external guide pipe and are uniformly distributed; namely, the medicine guiding holes are distributed with equal distances on longitudinal direction and are distributed with equal circumferential angles on circumference. The utility model has the advantages of reasonable design and simple structure, having obvious effect on enlarging the range of anesthesia blockade, reducing local anesthetic dosage and improving anesthesia success ratio; simultaneously the utility model has good effect on muscle loosing without negative reaction.
