Abstract
A surgical device and tool for use in stabilizing tissue, such as an organ relative to a clamp, the surgical device having an elongate rigid member with a proximal end of the device having a stabilizing structure that rests against the skin of the subject and includes a vessel guide for guiding a blood vessel attached to the organ or tissue, and a tapered distal end that mounts on the clamp. The surgical tool includes the combination of a clamp and the above-mentioned surgical device, with the clamp having a hinge pin with tapered socket that receives mounted the distal end of the device and a flap positioned on the proximal end. The tool is used to stabilize an organ by placement of the stabilizing structure against the skin of the subject, guiding a blood vessel with the vessel hook, using the flap to hold tissue away from the organ, and clamping such vessel distal to the vessel guide. A ligature is then placed across the vessel between the vessel guide and the clamp.
