Beschreibung
Zusammenfassung:	A suction activated instrumentation system for use in implanting an ossicular prosthesis into the middle ear includes a suction handpiece and a vacuum source. A removable suction tip is coupled to the handpiece for engaging an ossicular prosthesis. The suction tip includes a distal portion with an elongate slot opening at an end face, and two arms defined at the end face. When suction is applied through the suction tip, the prosthesis is drawn against the end face and retained between the arms. In the event the prosthesis is inadvertently contacted during implantation, the suction tip provides for self-correction, causing a prosthesis to re-orient into the prior intended configuration.
