Abstract

Claims (39)

1 . A system, comprising:

(a) a controller;

(b) a first robotic arm in communication with the controller and having a first head;

(c) a surgical scope coupled with the first head and having a scope shaft sized and configured to be inserted through an opening in a body wall and into a body cavity of a patient;

(d) a second robotic arm in communication with the controller and having a second head; and

(e) a surgical instrument coupled with the second head and having an instrument shaft sized and configured to be inserted through an opening in the body wall and into the body cavity of the patient;

wherein the controller is programmed to control the first robotic arm to manipulate the surgical scope relative to the patient while inhibiting the first head from entering a predefined zone of a robotic arm workspace that overlies the body wall, wherein the predefined zone comprises an instrument arm zone, wherein the controller is programmed to control the second robotic arm independently of the first robotic arm to constrain the second head within the instrument arm zone, wherein the controller is configured to control the first robotic arm to constrain the first head in a predefined scope arm zone that is arranged in a non-overlapping manner with the instrument arm zone,

wherein the instrument arm zone is positioned between the patient and the scope arm zone.

2 . The system of claim 1 , wherein the predefined zone includes an outer perimeter that is arcuate.

3 . The system of claim 2 , wherein the outer perimeter is defined by a predefined radius that extends from a predefined reference point associated with the patient.

4 . The system of claim 1 , wherein the scope arm zone has a first outer perimeter that extends to a first maximum distance from a predefined reference point associated with the patient, wherein the instrument arm zone has a second outer perimeter that extends to a second maximum distance from the reference point that is less than the first maximum distance.

5 . The system of claim 4 , wherein at least a portion of each of the first outer perimeter and the second outer perimeter is arcuate, wherein the portion of the first outer perimeter is defined by a first radius measured from the reference point and the portion of the second outer perimeter is defined by a second radius measured from the reference point that is less than the first radius.

6 . The system of claim 5 , wherein the controller is programmed to direct the first and second robotic arms to move the first and second heads within the respective scope arm zone and instrument arm zone simultaneously without collision between the first and second heads or between the surgical scope and the surgical instrument.

7 . The system of claim 1 , wherein the controller is configured to adjust the predefined zone during a surgical procedure on the patient.

8 . The system of claim 1 , wherein the first head includes a drive mechanism, wherein the surgical scope includes a scope base coupled to the drive mechanism, wherein the drive mechanism is operable to actuate the scope shaft relative to the scope base.

9 . The system of claim 8 , wherein the controller is configured to control the first robotic arm to move the scope shaft relative to the patient by at least one of actuating the scope shaft with the drive mechanism or articulating the first robotic arm.

10 . The system of claim 1 , wherein the surgical scope includes a scope base that is shaped and configured for handheld use by a user, wherein the scope shaft extends distally from the scope base, wherein the first head of the first robotic arm includes an adapter feature having a recess that is shaped and configured to receive the scope base.

11 . The system of claim 1 , wherein the scope shaft includes a deflectable distal shaft portion.

12 . The system of claim 11 , wherein the deflectable distal shaft portion is flexible.

13 . The system of claim 1 , wherein the instrument arm zone is defined by a first radius extending from a reference point, the reference point being associated with the body wall, such that the controller is programmed to prevent the second head from moving beyond the first radius.

14 . The system of claim 13 , the scope arm zone being defined between the first radius and a second radius, such that the controller is programmed to prevent the first head from moving beyond the second radius and within the first radius.

15 . The system of claim 13 , further comprising a cannula configured for insertion through the body wall, the canula defining a lumen sized to receive the surgical scope.

16 . The system of claim 15 , the controller being configured to define a remote center of motion of the cannula, the reference point corresponding to the remote center of motion.

17 . The system of claim 1 , the instrument arm zone being concentrically positioned relative to the scope arm zone.

18 . A system, comprising:

(a) a controller;

(b) a first robotic arm in communication with the controller and having a first head;

(c) a second robotic arm in communication with the controller and having a second head;

(d) a first surgical instrument coupled with the first head and having a first instrument shaft sized and configured to be inserted through an opening in a body wall and into a body cavity of a patient; and

(e) a second surgical instrument coupled with the second head and having a second instrument shaft sized and configured to be inserted through the body wall and into the body cavity,

wherein the controller is programmed to control the first and second robotic arms independently such that the first head is constrained to a first predefined zone external to the patient and the second head is constrained to a second predefined zone external to the patient,

wherein the first and second predefined zones are arranged in a non-overlapping manner,

wherein the second predefined zone is positioned between the patient and the first predefined zone.

19 . A method of operating a robotic system that includes a controller, a first robotic arm in communication with the controller and having a first head, a surgical scope coupled with the first head and having a scope shaft sized and configured to be inserted through an opening in a body wall and into a body cavity of a patient, a second robotic arm in communication with the controller and having a second head, and a surgical instrument coupled with the second head, the method comprising:

defining with the controller a first zone that overlies the body wall, the first zone extending between a first radius from a reference point associated with the body wall to a second radius from the reference point;

defining with the controller a second zone that overlies the body wall, the second zone being positioned between the first radius and the body wall;

while a distal end of the scope shaft is positioned within the body cavity, controlling the first robotic arm with the controller such that movement of the first head relative to the patient is constrained to the first zone, such that the first head is unable to enter the second zone; and

while a distal end of the surgical instrument is positioned within the body cavity, controlling the second robotic arm with the controller such that movement of the second head relative to the patient is constrained to the second zone, such that the second head is unable to enter the first zone.

20 . The method of claim 19 , wherein the first head includes a drive mechanism, wherein the surgical scope includes a scope base coupled with the drive mechanism, wherein the method further comprises moving the scope shaft relative to the patient by at least one of actuating the scope shaft with the drive mechanism or articulating the first robotic arm.
