1. A motorized surgical system, comprising:
- at least one support having a distal portion positionable within a sterile field in proximity to a patient positioned on a surgical table;
an instrument driver carried by the distal portion of said at least one support, the instrument driver comprising a steerable finger having a steerable distal end positionable in a body cavity, the distal end configured to removably receive a surgical instrument, the steerable finger including a lumen proportioned to receive a distal portion of a surgical instrument;
least one actuation element extends at least partially through the finger;
a user input device carried by the distal portion of said at least one support, the user input device configured to generate movement signals in response to manual manipulation of a portion of the user input device by a user;
at least one steering motor operably coupled to the instrument driver, the steering motor operable in response to the movement signals to cause tensioning of the actuation element so as to deflect the steerable distal end of the finger in response to the movement signals;
at least one roll driver carried by the distal portion of said at least one support, the roll driver positioned to rotationally couple with a shaft of a surgical instrument that is positioned through the lumen,a roll input device carried by the support, the roll input device configured to generate roll signals in response to manual manipulation of the roll input device; and
a roll motor, the roll motor operably coupled to the roll driver, the roll motor operable to move the roll driver in response to the roll movement signals to cause axial rolling of at least a portion of the shaft of a surgical instrument that is rotationally coupled with the roll driver.

Abstract
A surgical system includes an instrument driver having a distal end positionable in a body cavity and a user input device. The instrument driver and user input device are positioned to removably receive distal and proximal portions, respectively, of a surgical instrument. The user input device is configured to generate movement signals in response to manual manipulation of the proximal portion of the surgical instrument. At least one motor operable to actuate the instrument driver in response to the movement signals and to thereby change position of the distal portion of the surgical instrument within the body cavity.

6. A motorized surgical system, comprising:
-
at least one support having a distal portion positionable within a sterile field in proximity to a patient positioned on a surgical table; an instrument driver carried by the distal portion of said at least one support, the instrument driver comprising a steerable finger having a steerable distal end positionable in a body cavity, the distal end configured to removably receive a surgical instrument, the steerable finger including a lumen proportioned to receive a distal portion of a surgical instrument; least one actuation element extends at least partially through the finger; a user input device carried by the distal portion of said at least one support, the user input device configured to generate movement signals in response to manual manipulation of a portion of the user input device by a user; at least one steering motor operably coupled to the instrument driver, the steering motor is operable in response to the movement signals to cause tensioning of the actuation element so as to deflect the steerable distal end of the finger in response to the movement signals; wherein the steering motor comprises a motor housing and includes a drive member exposed on the motor housing; the instrument driver further includes an instrument driver housing; at least two actuation elements each having a distal portion anchored to the finger, a first pulley within the instrument driver housing and coupled to a proximal portion of one of the actuation elements, the first pulley including a first gear; a second pulley within the instrument driver housing and coupled to a proximal portion of one of the actuation elements, the second pulley including a second gear; a third gear engaged with the first and second gears; and a driven member exposed on the instrument driver housing; wherein the motor housing and the instrument driver housing are positionable to rotationally couple the driven member and the drive member such that activation of the motor rotates the third gear and the pulleys. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13, 14)
