ABSTRACT:
An apparatus for open-heart surgery includes a suture-needle holding tip (10) or a stapler and a handle (100). The tip is driven to oscillate relative to the handle in the same motion as the surface of the heart, which is being operated on. This cancels the motion of the heart, effectively stopping it, so that the surgeon (S) need not compensate for heart beats. The tip can grasp or release the needle (N) with a mechanism (300) under control of a switch (330) through a flexible cable 120. Independently, a drive mechanism 200 causes a cam (230) to be turned by a motor 213 for driving the needle-holding tip by means of a flexible cable 120. The cam is shaped so that the pattern of the platform oscillation follows the beating heart's motion. A momentary-contact switch triggers a pacer, which paces the heart to beat in synchrony with the motion of the needle-holding tip. The rate is set slightly above the un-paced heart beat rate.
