Surgical robotic tools, data architecture, and use
First Claim
1. A robotic surgical tool for use with a robotic surgical system, the tool comprising:
- a probe body comprising a proximal end and a distal end;
a surgical end effector disposed adjacent the distal end of the probe body, the end effector being movable in at least one degree of freedom relative to the probe body;
an interface disposed adjacent the proximal end of the probe body, the interface comprising a flat surface on which is disposed a plurality of driven elements, each of the plurality of driven elements comprising a rotatable body having an axis of rotation normal to the flat surface, the interface further comprising a releasable coupling mechanism for coupling to a tool holder of the robotic surgical system;
a drive system that couples the plurality of driven elements of the interface to the surgical end effector to move the surgical end effector; and
a tool memory coupled to the interface, the tool memory defining a signal for transmission to a processor of the robotic surgical system, wherein the interface further comprises at least one connecting pin coupled to the tool memory to transmit said signal, the at least one connecting pin provided on the flat surface of the interface.

Abstract
Robotic surgical tools, systems, and methods for preparing for and performing robotic surgery include a memory mounted on the tool. The memory can perform a number of functions when the tool is loaded on the tool manipulator: first, the memory can provide a signal verifying that the tool is compatible with that particular robotic system. Secondly, the tool memory may identify the tool-type to the robotic system so that the robotic system can reconfigure its programming. Thirdly, the memory of the tool may indicate tool-specific information, including measured calibration offsets indicating misalignment of the tool drive system, tool life data, or the like. This information maybe stored in a read only memory (ROM), or in a nonvolatile memory which can be written to only a single time. The invention further provides improved engagement structures for coupling robotic surgical tools with manipulator structures.
