ABSTRACT:
A rotatable surgical instrument for use alone or in conjunction with other instruments such as an endoscope. The instrument, having a proximal end and a distal end, includes a proximal actuator assembly, a distal end effector assembly having a surgical tool and a first rotational engagement member, a hollow member extending between the actuator and the end effector assembly, and a control member extending through the hollow member. The control member has a proximal end connected to the actuator assembly, a distal end connected to the end effector assembly, and a second rotational engagement member. In operation, actuation of the actuator assembly causes the control member to actuate the surgical tool, and the first engagement member engages the second engagement member to transmit torque applied to the control member to the end effector assembly.
