Performing surgery on fast-moving heart structures while the heart is freely beating is next to impossible. Nevertheless, the ability to do this would greatly benefit patients. By controlling a teleoperated robot to continuously follow the heart's motion, the heart can be made to appear stationary. The surgeon will then be able to operate on a seemingly(More)
Beating-heart surgery is not currently possible for most surgical procedures as it requires superhuman skill to manually track the heart's motion while performing a surgical task. However, if a surgical tool could track the motion of the point of interest (POI) on the heart, then, with respect to the surgical tool tip the POI would appear stationary. Such a(More)
Performing a surgical procedure on a beating heart is nearly impossible as the surgeon must simultaneously follow the heart’s motion and perform a surgical task. Assume the position of a target point for operation on the heart’s (interior or exterior) surface is captured in ultrasound images. If a robotic system could move a surgical tool in synchrony with(More)
Surgery on a freely beating-heart is extremely difficult as the surgeon must perform the procedure while following the heart's fast motion. However, by controlling a teleoperated robot to continuously follow the heart's motion, the surgeon can operate on a seemingly stationary heart. The heart's motion is calculated from ultrasound images and thus involves(More)
Physiological motion makes performing a surgical or therapeutic procedure more difficult for the physician. In heart surgery, the heart is stopped as it is too difficult for the surgeon to follow the heart’s beating motion and perform a surgical task. In radiation therapy, respiration causes the cancerous tissue to move, rendering the therapy less effective(More)
Operating on a beating heart would offer many benefits to patients. The risks associated with heart-lung machines used in arrested-heart surgery would be eliminated and the effectiveness of reconstructive procedures could be judged immediately. However, the heart's fast beating motions make operating on a beating heart impossible for the surgeon. With(More)
Performing a surgical task on a beating heart requires superhuman skill as the surgeon must manually track the heart’s motion while performing a surgical task. However, the ability to operate on a beating heart would eliminate the need to use a mechanical stabilizer or arrest the heart and connect the patient to a heart-lung machine and would consequently(More)
