摘要:
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.

摘要:
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.
摘要:
A medical robotic system with a handle assembly that is used to control a medical instrument. The handle assembly and medical instrument have five degrees of freedom. Five degrees of freedom may provide greater dexterity than medical robotic systems of the prior art with four or less degrees of freedom. Five degrees of freedom reduces the size and complexity of the instrument.
摘要:
A robotic system that moves a surgical instrument in response to the actuation of a foot pedal that can be operated by the foot of a surgeon. The robotic system has an end effector that is adapted to hold a surgical instrument such as an endoscope. The end effector is coupled to a robotic arm assembly which can move the endoscope relative to the patient. The system includes a computer which controls the movement of the robotic arm in response to input signals received from the foot pedal.
