Performing cardiac surgery without cardioplegia
First Claim
1. A method of performing a surgical procedure on a beating heart of a patient, the method including:
- positioning an end effector in close proximity to a surgical site on the heart, at which site the surgical procedure is to be performed, the end effector being mounted on a robotically controlled arm;
bracing the beating heart to at least reduce motion of the surgical site;
monitoring motion of the surgical site;
computing end effector tracking command signals in response to monitored motion of the surgical site;
forwarding the tracking command signals to actuators operatively associated with the robotically controlled arm to cause the arm to move the end effector generally to track motion of the surgical site;
inputting an end effector movement command signal; and
forwarding the end effector movement command signal to the actuators to cause the end effector to move relative to the surgical site so as to perform at least part of the surgical procedure at the surgical site.

Abstract
Systems and methods are provided for performing a surgical procedure on a beating heart of a patient. Methods are provided which include positioning an end effector in close proximity to a surgical site on the heart, the end effector being mounted on a robotically controlled arm. The motion of the surgical site is monitored and end effector tracking command signals computed in response to the monitored motion of the surgical site. The tracking command signals are forwarded to actuators operatively associated with the robotically controlled arm to cause the arm to move the end effector generally to track motion of the surgical site. The method further includes inputting an end effector movement command signal, and forwarding the end effector movement command signal to the actuators to cause the end effector to move relative to the surgical site so as to perform at least part of the surgical procedure.

forwarding the end effector movement command signal to the actuators to cause the end effector to move relative to the surgical site so as to perform at least part of the surgical procedure at the surgical site;
directing an image capture device at the surgical site to capture at least one image of the surgical site; and
processing information related to the at least one image to create in an image of the surgical site which appears as though the surgical site were generally stationary relative to the image capture device. - View Dependent Claims (28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50)

52. A system for performing a surgical procedure on a beating heart of a patient, the system including:
-
a robotically controlled arm having an end effector mounted thereon, the end effector positionable in close proximity to a surgical site on the heart at which site the surgical procedure is to be performed;
a brace member operatively coupled with the robotically controlled arm, the brace member being arranged to brace, or stabilize, the beating heart so as at least to reduce motion of the surgical site on the beating heart at which site the surgical procedure is to be performed;
means for monitoring motion of the surgical site;
means for computing end effector tracking command signals in response to monitored motion of the surgical site;
means for forwarding the tracking command signals to actuators operatively associated with the robotically controlled arm to cause the arm to move the end effector generally to track motion of the surgical site;
means for inputting an end effector movement command signal; and
means for forwarding the end effector movement command signal to the actuators to cause the end effector to move relative to the surgical site so as to perform at least part of the surgical procedure at the surgical site.
