ABSTRACT:
A laparoscopic surgical instrument is disclosed. The instrument generally comprises an elongated hollow shaft having at one end a pair of scissors and at the opposite end a pair of handles to control the scissors. The blades may be opened and closed when one handle is pivoted while the other handle is fixed. However, when both handles are rotated simultaneously the orientation of the blades relative to shaft changes so as to allow the blades to effectively cut or grasp curved tissues lying in a plurality of planes. Additionally, apparatus is provided to allow the blades to rotate about the longitudinal axis extending therethrough.
A depth gauge for laparoscopic scissors is also disclosed.
