<p>A microsurgical scissors uses a rotary cutting action and biased blades (13, 14) that intersect in a travelling point of contact. One blade (13) is situated on the end of a tubular shaft (11) and a second blade (14) on a rod (12) that is rotatable within the shaft (11). The blades (13, 14) are angled so the blades intersect at a point of contact. To assure a precise shearing relationship, the rod (12) is biased rearward in order to bear the rod blade (14) against the shaft blade (13). An actuating mechanism (23, 25) in the handle (10) translates a linear finger motion into rotary motion of the rod. The blades (13, 14) cut clearly and surely without imparting undue tissue trauma. </p> |
