ABSTRACT:
A hand-held surgical instrument with an improved handle, the instrument being of the type generally comprised of a handle and a tool with a body member having at least one articulated member thereon, is provided. The handle has an elongated base, an elongated lever with a downwardly projecting actuator arm and a member for connecting the lever and base at a rearward pivot point, which mimics the natural pivot point of the surgeon's hand. A member for actuating the surgical tool by moving an actuator rod distally by closing the handle lever, and a member for biasing the lever in an open position longitudinally positioned around the actuator rod within the base, are provided. The instrument includes a member for securing the handle at selected points throughout a range of motion or, alternatively, allowing motion that is not locked at any position. Also provided is a collar for allowing rotation of the tool to a desired radial orientation and adjustably securing the tool in that orientation.
