Abstract
An apparatus for performing a minimally-invasive procedure having a shaft with a flexible portion that extends distally from a handle portion and an actuatable tool head assembly that includes a sharp cutting implement at its other end. The handle portion includes an actuatable trigger operatively connected to a pull member such that actuation of the trigger moves the pull member and selectively positions the actuatable tool head assembly.
Claims20
An apparatus for performing a minimally-invasive procedure, the apparatus comprising:
- a shaft having a distal end, a proximal end and a central portion extending between the distal end and the proximal end,
- wherein the shaft comprises a flexible portion that extends distally from a handle portion at the proximal end of the shaft, said shaft having at its distal end an actuatable tool head assembly comprising a sharp cutting implement;
- wherein the handle portion comprises a first actuatable trigger operatively connected to a pull member at least substantially disposed within the central portion;
- whereby actuation of the trigger is operative to move the pull member to thereby selectively position the actuatable tool head assembly, said pull member comprising at least one cord operatively connected to the handle portion and that extends through a center of the central portion.

- wherein the shaft comprises a flexible portion that extends distally from a handle portion at the proximal end of the shaft, said shaft having at its distal end an actuatable tool head assembly comprising a sharp cutting implement;
- wherein the handle portion comprises a first actuatable trigger operatively connected to a pull member at least substantially disposed within the central portion,
- whereby actuation of the trigger is operative to move the pull member to thereby selectively position the actuatable tool head assembly;
- said pull member comprising at least one cord operatively connected to the handle portion and that extends through a center of the central portion;
- and
- a knob positioned near the handle portion adapted to cause movement of the actuatable tool head assembly by manual adjustment of the knob.
