A microsurgical scissors uses a rotary cutting action and biased blades that intersect in a travelling point of contact. One blade is situated on the end of a tubular shaft and a second blade is on a rod that is rotatable within the shaft. The blades are angled so their cutting edges intersect each other. To assure a precise shearing relationship, the rod is biased rearward in order to bear the cutting edge of the rod blade against the cutting edge of the shaft blade. An actuating mechanism in the handle translates linear finger motion into rotary motion of the rod. The blades cut cleanly and surely without imparting undue tissue trauma.
