ABSTRACT:
A microsurgical instrument providing scissor action cutting elements at the end of an elongated tubular housing. The cutting elements are at the free end of a tubular housing that is adapted to be inserted into a surgery site and has one end attached to a motion producing portion of the instrument that is outside the surgery site. The cutting elements are formed at extensions of elongated shaft members one of which reciprocates within the tubular housing. One of the elongated shafts is fixed within the tubular housing near the end attached to the motion producing portion. The elongated shaft members are formed adjacent to the free end of the tubular member to maintain the scissor action cutting elements in firm engagement.
