More Information
Summary:A surgical instrument includes an elongated body operably connected to a jaw member and a blade. The elongated body includes an inner tube and an outer tube configured to move laterally with respect to one another. A drive arm has a first end engaged to the outer tube and a second end pivotably coupled to the jaw member configured to move laterally in tandem with the outer tube such that motion of the outer tube in a first direction pulls the jaw member away from the blade, and motion of the outer tube in a second direction pushes the jaw member towards the blade. The drive arm includes a semi-rigid material configured to flex when compressed, such that flexion of the drive arm can offload excess force exerted by the outer tube on the jaw member.
