Abstract

Devices, systems and methods for detecting a position of an object with a robot surgical system having an articulable, separable camera stand. The surgical robot system may include a robot having a robot base with a robot arm and an end-effector coupled to the robot arm. The end-effector, surgical instruments, the patient, other objects, or any combination thereof, may be tracked via active and/or passive tracking markers. A camera, such as an infrared camera, a bifocal camera or a stereophotogrammetric infrared camera, is mounted on a separable camera stand and is able to detect the tracking markers when in use. Using the camera, the robot determines a position of the object from the tracking markers, which may be a three-dimensional position of the object or the markers. When convenient, the camera base may be assembled into the robot base, e.g., by sliding the camera base into the robot.

First claim

What is claimed is:

1 . A method for a camera stand to interact with a surgical robot system comprising:
providing a camera stand including:
a base having at least one wheel; and
a plurality of legs that are rotationally coupled to the base and rotatable between a closed attaching position and an open deployed position, each leg having a wheel;
providing a surgical robot system having a robot base and a robot arm coupled to the robot base; placing the legs in the closed attaching position; moving the camera stand with the legs in the closed attaching position to the robot base; and locking the camera stand to the robot base for transporting the surgical robot system with the locked camera stand together as a single unit.

2 . The method of claim 1 , wherein moving the camera stand includes moving the camera stand such that the legs in the closed attaching position are positioned in a recess of the robot base.

3 . The method of claim 1 , wherein moving the camera stand includes moving the camera stand until the wheels of the base and the legs are off the ground.

4 . The method of claim 2 , wherein:
the recess includes a ramp having a sloped portion and a level portion; and moving the camera stand includes pushing the legs of the camera stand into the sloped portion and then the level portion of the ramp.

5 . The method of claim 1 , further comprising:
unlocking the camera stand from the robot base; and moving the camera stand away from the robot base such that the legs in the attaching position are automatically placed into the open deployed position.

6 . The method of claim 1 , wherein the legs of the camera stand comprise a left leg pivotally mounted to the base of the camera stand via a left leg pivot and a right leg pivotally mounted to the base of the camera stand via a right leg pivot.

7 . The method of claim 6 , wherein the left and right pivots each have a gear in engagement with each other.

8 . The method of claim 1 , wherein:
the camera stand includes cameras adapted to detect a plurality of tracking markers mounted on at least one of: the robot arm; an end-effector of the robot arm; a tool of the end effector; and a patient; and the robot and the cameras are adapted to determine a 3 -dimensional position of the robot arm, the end-effector, the tool or the patient via one or more of the plurality of tracking markers.

9 . The method of claim 8 , wherein:
the one or more of the tracking markers are active markers having an active state and an inactive state, the active state emitting an infrared signal detected by the cameras, and the inactive state not emitting the infrared signal such that the one or more of the tracking markers are not detected by the cameras.

10 . A method for a camera stand to interact with a surgical robot system comprising:
providing a camera stand having navigation cameras for tracking optical tracking markers, the camera stand including:
a base having at least one wheel; and
a plurality of legs that are rotationally coupled to the base and rotatable between a closed attaching position in which the legs are brought together and an open deployed position in which the legs are spread apart from each other, each leg having a wheel;
providing a surgical robot system having a robot base and a robot arm coupled to the robot base; placing the legs in the closed attaching position; moving the legs in the closed attaching position to a recess of the robot base; and after moving the legs to the recess of the robot base, locking the camera stand to the robot base for transporting the surgical robot system with the locked camera stand together as a single unit.

11 . The method of claim 10 , wherein moving the camera stand includes moving the camera stand into the recess until the wheels of the base and the legs are off the ground.

12 . The method of claim 10 , wherein:
the recess includes a ramp having a sloped portion and a level portion; and moving the camera stand includes pushing the legs of the camera stand into the sloped portion and then the level portion of the ramp.

13 . The method of claim 10 , further comprising:
unlocking the camera stand from the robot base; and moving the camera stand away from the robot base such that the legs in the attaching position are automatically placed into the open deployed position.

14 . The method of claim 10 , wherein the legs of the camera stand comprise a left leg pivotally mounted to the base of the camera stand via a left leg pivot and a right leg pivotally mounted to the base of the camera stand via a right leg pivot.

15 . The method of claim 14 , wherein the left and right pivots each have a gear in engagement with each other.

16 . The method of claim 10 , wherein:
the cameras are adapted to detect a plurality of optical tracking markers mounted on at least one of: the robot arm; an end-effector of the robot arm; a tool of the end effector; and a patient; and the robot and the cameras are adapted to determine a 3-dimensional position of the robot arm, the end-effector, the tool or the patient via the one or more of the plurality of optical tracking markers.

17 . The method of claim 16 , wherein:
the one or more of the optical tracking markers are active markers having an active state and an inactive state, the active state emitting an infrared signal detected by the cameras, and the inactive state not emitting the infrared signal such that the one or more of the tracking markers are not detected by the cameras.

18 . The method of claim 10 , further comprising detecting, through the cameras, a 3-dimensional position of a plurality of optical tracking markers mounted on the end-effector of the robot arm, a tool held by the end effector and the patient simultaneously.
