A rongeur surgical instrument is disclosed which has an actuating mechanism providing a variable degree of mechanical advantage for operation of the cutting element in the instrument. During the cutting stroke the rate of movement steadily decreases, while the degree of precision of movement and the amount of torque increase throughout the stroke. The instrument also has an improved shaft design which maintains cutting edge alignment with the footplate anvil surface, and also provides a mechanism for preventing cut portions of body material from aggregating near the distal end of the shaft and interfering with the cutting operation. In addition, the grip portion of the instrument has an adjustable spur member to allow the grip portion to comfortably fit a variety of hand sizes.
