Method and apparatus for performing minimally invasive cardiac procedures
First Claim
1. A medical robotic system comprising:
- a robotic arm;
a surgical instrument detachably coupled to the robotic arm;
a master input device; and
a controller coupled to the master input device, the robotic arm, and the surgical instrument so as to translate movement of the master input device into corresponding movement of the surgical instrument according to a master-slave relationship, wherein the controller has a filter that filters a portion of an output of the master input device that corresponds to a hand tremor of an operator manipulating the master input device.

Abstract
A minimally invasive surgical system includes a pair of surgical instruments having end effectors to hold and suture tissue, a pair of robotic arms coupled to the surgical instruments, a controller, and a pair of master handles coupled through the controller to the robotic arms, so that surgeon manipulation of the handles produces corresponding movement of the end effectors in an adjustably scaled fashion. An input button allows the surgeon to adjust the position of the handles without moving the end effectors, so that the handles may be moved to a more comfortable position. An optionally included robotically controlled endoscope allows the surgeon to remotely view the surgical site. Using the system, a cardiac procedure can be performed by making small incisions in the patient'"'"'s skin, inserting the instruments and endoscope through the incisions, and manipulating the handles to move the end effectors to perform the cardiac procedure.
