Abstract

A surgical apparatus for performing a surgical procedure such as severing tissue in microsurgical operations. In the case of a cutting implement, the apparatus includes an elongated rigid housing having an inner wall and supporting therein first and second elongated shaft members. The first and second shaft members each have juxtaposed inner surfaces slidable relative to each other and outer surfaces terminating in corners which abut and are slidable relative to the inner tubular wall. The first shaft has a driven end and an active or operable cutting end having a first cutting edge disposed outside of the tubular housing. The second shaft has a fixed end and a cutting end with a second cutting edge also disposed outside of the tubular housing. Drive means are connected to the driven end of the first shaft for causing axial reciprocatory movement of the first cutting edge through a predetermined stroke distance to carry the first cutting edge past the second cutting edge to effect cutting action.
