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 structure for connecting the lever and base at a rearward pivot point, which mimics the natural pivot point of the surgeon's hand. The surgical tool may be activated by moving an actuator rod distally by closing the handle lever. The lever may be biased by a spring longitudinally positioned around the actuator rod within the base, in an open position. The instrument includes structure 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.
