ABSTRACT:
A surgical tool for removing a block of tissue or other material from an organ or other body has an elongated support element which carries a first blade assembly including a pair of arms pivotally mounted about a first transverse axis, and a first blade element pivotally mounted to the arms. A second blade element is also pivotally mounted to the support element. A mechanical actuation arrangement is configured to resiliently bias the first blade assembly and the second blade element from in-plane positions towards deflected positions for initiating a predefined cutting sequence for removal of the block of tissue.
