Abstract
Unitary endoscopic vessel harvesting devices with an elastic force are disclosed. In some embodiments, such devices comprise an elongated body having a proximal end and a distal end, a tip disposed at the distal end of the elongated body. The tip having a visual cue indicating a location of at least one cutting element extending from the elongated body.
Claims22
A surgical device comprising:
- an elongated body terminating in a tip at a distal end of the body;
- a cutting unit having a first cutting portion and a second cutting portion moveable in a longitudinal direction relative to the elongated body toward the distal end, at least one cutting portion being rotatable relative to the other cutting portion circumferentially about the tip;
- and
- a visual cue on the tip to designate a location of at least one cutting portion when it is moved longitudinally over the tip at the distal end of the elongated body.

A method for harvesting a blood vessel, the method comprising:
- advancing an elongated body having, at its distal end, a dissection tip along a main vessel to separate the main vessel and its branch vessels from surrounding tissue;
- orientating a visual cue on the dissection tip for visual confirmation for positioning of the dissection tip;
- and
- moving a first cutting portion and a second cutting portion towards the distal end while using the visual cue as a point of reference to capture a blood vessel between the first and second cutting portions.
