More Information
Summary:An actuating mechanism is provided for a hand-operated surgical instrument having at least one operating member. The operating member is engaged by or extends from a flexible pusher member wound at least partially around the circumference of a drum and secured thereto. A pinion is connected to the drum for rotation therewith and is driven by a gear segment on a handle that is pivotally monted to the instrument. A full stroke compelling mechanism is associated with the drum for preventing return of the handle to the unactuated position unless and until the operating member has been moved through the full design range of movement.
