A surgical instrument includes a first member that has an opening in its distal region for admitting tissue and that is rotatable with respect to a base from which the first member extends to allow the rotational orientation of the opening to be selectively changed with respect to the axis of the instrument. A second member is disposed within the first member to transmit force to move a cutting implement disposed at its distal end and cause it to cut tissue that is exposed to the implement through the opening. In another aspect of the invention, a surgical instrument includes a rigid member that has a bend region that angularly offsets a distal region from a proximal region mounted to a first section of a base; a surgical device extending distally from a second section of the base coaxially with the rigid member carries a surgical tool distal of the bend region, and is flexible at least in the bend region to transmit force applied at a proximal end of the surgical device through the bend region to operate the surgical tool; the first base section is rotatable with respect to the second base section, allowing the relative rotational orientation between the surgical tool and the bend region to be changed.

A surgical instrument disposed generally along an axis, said surgical instrument comprising a first member that extends distally from a base and has an opening in a distal region thereof for admitting tissue, said first member including a bend region that angularly offsets said distal region of said first member from said axis so that said distal region is aligned with a distal axis, a second member for moving a cutting implement and causing it to cut tissue that is exposed to said implement through said opening, and a rotator coupled to said first member for rotating said first member with respect to said base to rotate said opening around to said distal axis, said distal axis and said distal region remaining aligned as said first member rotates with respect to said base.
