Abstract
An adapter assembly for operably connecting an end effector to a handle assembly includes a first drive assembly. The first drive assembly includes a first connector drive shaft configured to be rotated at a first speed, a first proximal worm gear in operable engagement with the first connector drive shaft, a first distal worm gear in operable engagement with the first proximal worm gear, and a first drive connector in operable engagement with the first distal worm gear. The first proximal worm gear and the first distal worm gear are configured to rotate the first drive connector at a second speed which is less than the first speed. The adapter assembly may include a second drive assembly which is substantially similar to the first drive assembly.
