Surgical tool positioning based on sensed parameters
First Claim
1. A surgical system, comprising:
- an electromechanical arm configured for movement in multiple axes;
an electromechanical tool having an instrument shaft and an end effector formed thereon, the electromechanical tool being configured to be mounted on the electromechanical arm, and the electromechanical tool being configured to move with or relative to the electromechanical arm and apply energy to tissue engaged by the end effector; and
a controller operatively coupled to the electromechanical arm and the electromechanical tool, the controller configured to retard advancement of the electromechanical tool toward a tissue surface based on a sensed temperature of the end effector, wherein the controller is configured to retard advancement of the electromechanical tool when the end effector is within a predetermined threshold distance from a tissue surface, and wherein the predetermined threshold distance varies based on the temperature of the end effector.

Abstract
Devices, systems, and methods are provided in which movement of a tool is controlled based on sensed parameters. In one embodiment, an electromechanical tool is provided having an instrument shaft and an end effector formed thereon. The electromechanical tool is configured to be mounted on an electromechanical arm, and the electromechanical tool is configured to move with or relative to the electromechanical arm and perform surgical functions. A controller is operatively coupled to the electromechanical arm and the electromechanical tool and is configured to retard advancement of the electromechanical tool toward a tissue surface based on a sensed amount of displacement of a tissue surface, a strain on the tissue of the patient, the temperature of the electromechanical tool, or the like.
