Assignee:
The Johns Hopkins University - Baltimore MD
International Classification:
A61B 6/00
US Classification:
600476
Abstract:
An observation system for viewing light-sensitive tissue includes an illumination system configured to illuminate the light-sensitive tissue, an imaging system configured to image at least a portion of the light-sensitive tissue upon being illuminated by the illumination system, and an image display system in communication with the imaging system to display an image of the portion of the light-sensitive tissue. The illumination system is configured to illuminate the light-sensitive tissue with a reduced amount of light within a preselected wavelength range compared to multispectral illumination light, and the image of the portion of the light-sensitive tissue is compensated for the reduced amount of light within the preselected frequency range to approximate an image of the light-sensitive tissue under the multispectral illumination

Tool Exchange Interface And Control Algorithm For Cooperative Surgical Robots
US Patent:
2014006, Mar 6, 2014
Filed:
Aug 2, 2011
Appl. No.:
13/813717
Inventors:
Russell H. Taylor - Severna Park MD, US

Assignee:
THE JOHNS HOPKINS UNIVERSITY - Baltimore MD
International Classification:
A61B 19/00
US Classification:
606103
Abstract:
A system and method for tool exchange during surgery for cooperatively controlled robots comprises a tool holder for receiving a surgical tool adapted to be held by a robot and a surgeon, a tool holding element for constraining downward motion of the tool while allowing low force removal of the surgical tool from the holder, a first sensor for detecting if the surgical tool is docked within the tool holder, and a selector for automatically selecting different movements or actions of the tool holder to be performed based upon information detected by the first sensor. The system and method of the present invention provides an advantage to an often slow moving cooperative robot, by increasing the speed by which the tool holder may move in the direction away from the patient.

International Classification:
A61B 19/00, A61B 3/10, A61B 5/00, A61F 9/007
US Classification:
606130
Abstract:
A system and method for cooperative control of surgical tool includes a tool holder for receiving a surgical tool adapted to be held by a robot and a surgeon, a sensor for detecting a force based on operator input and/or tool tip forces, a controller for limiting robot velocity based upon the force detected so as to provide a haptic feedback, a selector for automatically selecting one level of a multi-level audio feedback based upon the detected force applied, the audio feedback representing the relative intensity of the force applied, and an audio device for providing the audio feedback together with the haptic feedback. The audio feedback provides additional information to the surgeon that allows lower forces to be applied during the operation.
Micro-Force Guided Cooperative Control For Surgical Manipulation Of Delicate Tissue
US Patent:
2013030, Nov 14, 2013
Filed:
Aug 2, 2011
Appl. No.:
13/813738
Inventors:
Russell H. Taylor - Severna Park MD, US

Assignee:
THE JOHNS HOPKINS UNIVERSITY - Baltimore MD
International Classification:
A61B 19/00
US Classification:
700260
Abstract:
A method and system for micro-force guided cooperative control that assists the operator in manipulating tissue in the direction of least resistance. A tool holder receives a surgical tool adapted to be held by a robot and a surgeon. A first sensor measures interaction forces between a tip of the surgical tool and tissue of a region of interest. A second sensor measures interaction forces between the surgeon and a handle to the surgical tool. A data processor is configured to perform an algorithm to actively guide the surgical tool by creating a bias towards a path of least resistance and limit directional tool forces of the surgical tool as a function of handle input forces and tip forces. This function offers assistance to challenging retinal membrane peeling procedures that require a surgeon to delicately delaminate fragile tissue that is susceptible to hemorrhage and tearing due to undesirable forces.
