Clamping forceps and associated methods are provided that generally include a head section including first and second clamp members configured to cooperatively clamp so as to at least partially encircle a tumor or other structure, an elongated body section in cooperation with the head section, and a clamping mechanism at least partially movably mounted with respect to the elongated body section. The clamping forceps may include a control mechanism for variably controlling the clamping force, at least one sensor mounted with respect to the clamp member(s), means for fixating the clamp member(s) relative to tissue, the first and second clamp members structured to define a variable perimeter extent, and a clamping mechanism which accommodates variable rates of clamping action. Actuation of the clamping mechanism generally maintains substantially parallel actuation of the first and second clamp members with respect to the tumor or the other anatomical structure. Methods for use of the clamping forceps may include introducing the head section to the surgical site through an incision; positioning a trocar port at the surgical site; introducing at least a portion of the elongated body section to the surgical site through the trocar port; intra-corporeally connecting the head section with respect to the elongated body section; and extra-corporeally actuating the clamping mechanism so as to actuate the first and second clamp members into a clamping position around the tumor or other anatomical structure. |
