ABSTRACT:
A surgical instrument in which a surgical tool is carried distally of a bend region in a stationary support member by an assembly that transmits proximally applied forces through the bend region to both operate the surgical tool and selectively change the rotational orientation of the surgical tool with respect to the stationary member. In another aspect, in which the stationary member does not include a bend region, a rotatable member supported by the stationary member transmits rotational force to the surgical tool to selectively change the rotational orientation of the tool, and a driver member supported by the stationary member transmits axial force to the surgical tool to operate it. In still another aspect in which the stationary member includes the bend region but the surgical tool is not rotatable, a movable member supported by the stationary member is constructed to transmit a proximally applied axial force through the bend region to operate a surgical tool disposed in a distal region of the instrument.
