Surgical instrument having a rotational ring

摘要

A surgical instrument having a rotational ring is described. In one implementation, the surgical instrument includes a handle and a rotational ring. The handle includes at least one actuator member configured to operate a surgical tool located at a tip of the surgical instrument by moving the actuator member. The rotational ring is positioned in substantially close proximity to the one or more actuator members. Rotation of the rotational ring causes the surgical tool located at the tip of the surgical instrument to rotate in a corresponding rotational fashion.
