Microsurgical scissor apparatus with rotary cutting blade

摘要

A microsurgical instrument providing scissor action cutting elements at the end of an elongated tubular housing. One of the cutting elements is rotated with respect to the other in a plane transverse to the axis of the 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 located at the end of the elongated tubular housing and are transverse to the axis of the housing. A stationary cutting blade is fixed to the housing and a rotatable cutting blade having a shaft is supported within the tubular housing. The motion producing portion of the instrument is hand-holdable and includes mechanical elements for converting reciprocal motion into rotary motion for operation of the rotatable cutting blade.
