Method and apparatus for performing minimally invasive cardiac procedures
First Claim
1. A medical robotic system that can be inserted through a first incision of a patient and controlled by a surgeon, comprising:
- a first articulate arm which has a passive joint that is coupled to a first end effector inserted into the incision, wherein the incision defines a first pivot point for said first end effector;
a first input device that creates a first input command in response to an instruction from the surgeon; and
,a controller that is coupled to said first input device and said first articulate arm, said controller receives said first input command from said first input device and provides a first output command to said first articulate arm to move said first end effector relative to the first pivot point.

Abstract
A system for performing minimally invasive cardiac procedures. The system includes a pair of surgical instruments that are coupled to a pair of robotic arms. The instruments have end effectors that can be manipulated to hold and suture tissue. The robotic arms are coupled to a pair of master handles by a controller. The handles can be moved by the surgeon to produce a corresponding movement of the end effectors. The movement of the handles is scaled so that the end effectors have a corresponding movement that is different, typically smaller, than the movement performed by the hands of the surgeon. The scale factor is adjustable so that the surgeon can control the resolution of the end effector movement. The movement of the end effector can be controlled by an input button, so that the end effector only moves when the button is depressed by the surgeon. The input button allows the surgeon to adjust the position of the handles without moving the end effector, so that the handles can be moved to a more comfortable position. The system may also have a robotically controlled endoscope which allows the surgeon to remotely view the surgical site. A cardiac procedure can be performed by making small incisions in the patient'"'"'s skin and inserting the instruments and endoscope into the patient. The surgeon manipulates the handles and moves the end effectors to perform a cardiac procedure such as a coronary artery bypass graft.

13. A system that allows a surgeon to perform a procedure on a patient, comprising:
-
a first articulate arm which has a first end effector; a first input device that can be moved a first input device spatial increment by the surgeon to create a first input command; a controller that is coupled to said first input device and said first articulate arm, said controller receives said first input command from said first input device and provides a first output command to said first articulate arm to move said first end effector; and
,a second input device that activates said first articulate arm so that said first end effector moves in conjunction with said first input device and deactivates said first articulate arm so that said first end effector remains stationary while the surgeon moves said first input device. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25)
