Guided tool change
First Claim
1. A method of performing minimally invasive robotic surgery in a body cavity of a patient, the method comprising:
- recording an operating position at which the first robotic surgical tool is disposed inside the cavity, the first robotic surgical tool being configured to effect a treatment of a tissue in the cavity;
removing the first robotic surgical tool from the cavity;
determining the desired location within the body cavity of a second robotic surgical tool based on the recorded position of the first robotic tool;
introducing the second robotic surgical tool into the cavity; and
guiding the second robotic surgical tool to the desired location in close proximity to the operating position.

Abstract
A guided tool change procedure is employed in minimally invasive robotic surgery to guide a new tool quickly and precisely, after a tool change operation, back into close proximity to the operating position of the original tool prior to its removal from the surgical site. A first robotic surgical tool is placed at an operating position inside the cavity using a slave manipulator disposed outside the cavity, and the operating position is recorded. The first robotic surgical tool is decoupled from the slave manipulator and removed from the cavity. A second robotic surgical tool is introduced into the cavity. Based on the recorded operating position, a target space is derived for placing the distal end of the second robotic surgical tool in close proximity to the location of the distal end of the first robotic surgical tool in the operating position prior to its removal from the cavity. A controller is provided to control the slave manipulator to guide the distal end of the second robotic surgical tool, during insertion of the second tool, to a location within the target space.

18. A surgical robotic system comprising:
- a slave manipulator for coupling with and actuating a robotic surgical tool inside a body cavity of a patient;
a controller configured to control movement of the slave manipulator and the robotic tool;
at least one sensor coupled with the slave manipulator and the controller for sensing an operating position of the robotic surgical tool coupled with the slave manipulator;
said controller comprising a computer, said computer having a first set of computer instructions for controlling the slave manipulator, after the first robotic surgical tool is removed from the cavity and decoupled from the slave manipulator, to automatically position the slave manipulator so that the second robotic surgical tool can be guided to a location in close proximity to the sensed operating position, the first robotic surgical tool being configured to effect a treatment of a tissue in the cavity. - View Dependent Claims (19, 20, 21, 22, 23)

24. A method of delivering a robotic surgical instrument having a distal tip to a surgical site, comprising:
-
determining, via a computer, a target space for a preset portion of the robotic surgical instrument to occupy upon delivery to the surgical site, based at least in part on a location in the surgical site previously occupied by another surgical instrument configured to effect a surgical treatment in the surgical site, wherein said location in the surgical site was sensed using a sensor during the surgical treatment by said another surgical instrument; and
guiding delivery of the robotic surgical instrument to the surgical site such that the instrument is delivered into the target space. - View Dependent Claims (25, 26, 27, 28, 29, 30, 31, 32, 33)
