–  Prothetic devices, artificial limbs, orthotic devices, … –  Active implants, functional electro-stimulation, … –  Robotic moving and manipulation aids, smart living spaces, … –  Rehabilitation robotics for therapy and training

I.1 Definitions (2)

What robotics can do (to assist doctors) … Automation and Robotic tasks: 1.  Registration: localization of the instrument with respect to the patient

with reference to the pre-operative planning thanks to intra-operative imaging and 3D measurement devices.

2.  Positioning : 3D positioning of instruments with respect to the patient 3.  Trajectory tracking: tracking with the instrument of a planned trajectory

with respect to the patient 4.  Comanipulation : manual manipulation of an instrument constraint in

position, velocity or force, by a robotic device 5.  Telemanipulation : telemanipulation from a distance of an instrument 6.  Exploration: exploration of a partially unknown environment 7.  Simulation: execution of the previous tasks in a virtual environment with

a physical human-machine interface

I.1 Definitions (3) A.  Registration:

Localization of the instrument with respect to the patient with reference to the pre-operative planning thanks to intra-operative imaging and 3D measurement devices.

•  Devices: 3D measurements –  Cameras (ex. Polaris, NDI) –  Magnetic sensors –  Medical imaging (ultrasound, fluoroscopy, scanner, MRI, …) –  Any other 3D measurement device…

•  Research issues –  Physiological motion compensation –  Modalities –  OR integration –  Precision and robustness

•  Main medical applications –  Orthopedics –  Neurosurgery –  Maxillio-facial surgery –  Radiotherapy

I.2 Specific issues (1)

•  Safety The robot is expected to create no injuries to the patient or

the medical staff: –  Redundant sensors –  Workspace, velocity, force constrains –  Safe mechanical design –  Software, electronic and mechanical fuses –  Manual procedure remains possible –  Automatic docking –  Small relative increase of the duration of the surgery –  Surgeon in the loop –  Others


•  Operating Room constrains The OP Room constrains should be taken into

account:

–  Available space –  Human-machine interface and ergonomy –  Training of the medical staff –  Interoperability with other equipements –  Certification –  Others


•  Sterility

Le robotic device should be compatible with the sterility procedures:

–  The parts in contact with the patient should go into an

autoclave or should be disposable or could go through a chemical cleansing

–  The other part in the sterile area should be wrapped in sterile bags in order to avoid contamination of the medical staff performing the surgical act

–  Others

I.3 Succesfull medical assistance (1)

•  Speed •  Accuracy •  Repeatability •  Automatic registration with pre-operative data •  Simulation •  Force, velocity and positioning constrains •  Augmented reality (visual, haptics, …) •  Gravity compensation •  Scaling of motions and forces •  Telemanipulation •  Automatic planned trajectory tracking •  Hostile environment •  Real-time integration of intra-operative data •  Added dexterity •  Tremor filtering •  Recording of intra-operative data

Expected added-values of robotics and automation:

I.3 Succesfull medical assistance (2)

Conditions for success: •  3 specific issues are taken into account : safety, sterility

and OP room constrains •  Several competitive advantages of robot over human are

realized •  The doctor is in the loop •  A significative improvement for the patient (validated

through clinical trials) •  An advantageous trade-off between cost and benefit for

the patient

Technological success is different from medical or commercial success
