Abstract
Abstract A robotic system that moves a surgical instrument in response to the actuation of a control panel that can be operated by 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 a patient. The system includes a computer which controls the movement of a robotic arm in response to input signals received from the control panel. The robotic system is mounted to a cart which can be wheeled to and from an operating table. The cart has a clamping mechanism which attaches the cart to the table. The system also contains a spring loaded mount plate that allows the robotic arm to be rotated and adjusted relative to the cart and the patient. Both the robotic arm and the control panel are encapsulated by protective bags that prevent the system from being contaminated.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
104 words
A surgical apparatus that manipulates a surgical instrument, comprising: an end effector for holding the surgical instrument; a first linkage arm connected to said end effector; a first active actuator which has an output shaft that is connected to said first linkage arm, said output shaft is moved by said first active actuator, said movement of said output shaft moves said first linkage arm and said end effector; a computer for controlling said first active actuator; and a first clutch that decouples said output shaft of said first active actuator from said first linkage arm to allow said end effector to be manually manipulated.
Claim 2
Dependent Claim
104 words
A surgical apparatus that manipulates a surgical instrument, comprising: an end effector for holding the surgical instrument; a first linkage arm connected to said end effector; a first active actuator which has an output shaft that is connected to said first linkage arm, said output shaft is moved by said first active actuator, said movement of said output shaft moves said first linkage arm and said end effector; a computer for controlling said first active actuator; and a first clutch that decouples said output shaft of said first active actuator from said first linkage arm to allow said end effector to be manually manipulated.
Claim 3
Dependent Claim
49 words
The apparatus as recited in claim 1, further comprising a second linkage arm that is connected to said first active actuator and an output shaft of a second active actuator and a second clutch that decouples said second linkage arm from said output shaft of said second active actuator.
Claim 4
Dependent Claim
36 words
The apparatus as recited in claim 2, wherein each of said first and second clutches is an electromagnetic device which disengages and allows manual manipulation of said end effector when power is terminated to said clutches.
Claim 5
Dependent Claim
25 words
The apparatus as recited in claim 1, further comprising a button that can be depressed to decouple said first active actuator from said end effector.
Claim 6
Dependent Claim
16 words
The apparatus as recited in claim 1, wherein said first active actuator is an electric motor.
Claim 7
Dependent Claim
28 words
The apparatus as recited in claim 1, further comprising an input device that is coupled to said computer, said input device for receiving command signals from a user.
Claim 8
Dependent Claim
26 words
The apparatus as recited in claim 1, further comprising a pair of passive joints that are coupled to said first linkage arm and said end effector.
