#IBIS pneumatic keyhole surgery robot potentially 1/10 the cost of Da vinci This is a robot system for keyhole surgery consisting of a master unit operated by the surgeon and a slave unit that moves on the patient side. feature of the slave robot is powered it entirely by air. Nearly all conventional robots are powered electrically but by driving this robot pneumatically wee made it possible to gently absorb the force when the robot touches something. The force on the tip of the robot is estimated from the air pressure data and that information is sent to the surgeon master robot. So it can be fed back to the surgeon hand. Alternatively a large force can be produced by a very lightweight compact unit. An advantage of this system is the robot overall can be made extremely compact.?Here the user is operating the master robot. This demonstration enables you to experience for example how you can feel the reaction force when you pull the rubber band.?Of course you can eliminate shaking of the hand change the motion ratio and change the force feedback factor. So depending on the medical staff and the situation the parameters can be varied to make the system easier to use on the spot.?Currently we aim to build this system for one-third to one-tenth the cost of the Da vinci surgical system. So we think we can make it better in terms of cost as well.?Right now wee working with surgeons who are actually using this system and giving us feedback on how to improve it. Wee receiving support from MEXT and we aim to achieve a practical version within 4 to 5 years. 4
