ABSTRACT OF THE DISCLOSURE An assembly designed for use in performing a canine ear or other implantation in order to correct a faulty ear carriage by erection of the ear, and comprising three basic surgical pieces or implements in the form of (1) an elongated shank (trocar) having a sharp incision-making distal or front end which is used to incise the ear so that the shank may be pushed along the general plane of the ear between the outer skin and the inner cartilage to create a duct which crosses over or bridges the weakened area of the cartilage, (2) an open-ended sheath (cannula) which is slidable onto the shank in close fitting relation and is adapted to be pushed into the duct as it is being created by the shank to the end that when the shank is withdrawn from the thus inserted sheath the latter remains within the duct and establishes an open-ended tunnel for reception of an ear-rigidifying implant, and (3) a pusher or thrust member which has a blunt forward end and is used to push the implant into the tunnel and consequently into the duct, and to hold it there while the sheath is being withdrawn. Withdrawal of the sheath from the duct by sliding it rearwardly on the thrust member, followed by withdrawal of the thrust member, leaves the implant embedded in the duct which hen collapses or shrinks on the implant. A minor suture closes the initial incision at the mouth of the duct and the implantation is thus completed in an execeptionally short length of time and with a minimum amount of pain and hemorrhage. :
