Device for positioning surgical tool in the body of patient

The present disclosure relates to a device for positioning and/or orienting, in the body of a patient, a surgical tool carried by a tool-holder, including a platform capable of being placed on the body of the patient, an orientable carrier, at least one part of which is rigidly connected to the tool-holder, means for guiding the orientable carrier rotationally relative to the platform in two directions of a plane parallel to the platform, at least 2 pneumatic actuators which engage with the orientable carrier such that a variation in pressure of at least one of the pneumatic actuators causes the orientable carrier to rotate in the first direction and/or the second direction, in which the pneumatic actuators are volumes that can deform in a predetermined direction as a function of the internal pressure

Actuadores de nitinol aplicados en la mimetización del sistema de propulsión de peces con median paired fin

Este artículo presenta una propuesta original para diseñar actuadores empleando una aleación con memoria de forma shape memory alloy conocida corno nitinol. La aplicación se centra en el uso de estos actuadores en un robot que mimetiza a los organismos poseedores de aletas de locomoción tipo median paired fin

Robots Modulares para Cirugía Mínimamente Invasiva

Este artículo se enfoca en las consideraciones que se deben tomar en cuenta sobre el diseño de robots modulares que permitan auxiliar al médico en intervenciones de CMI (Cirugía Mínimamente Invasiva). Se presenta el estado del arte de los sistemas robóticos modulares tanto re-configurables como auto re-configurables, así como los dispositivos y materiales quirúrgicos usados en cirugía de mínima invasión con el fin de tomarlos como referencia en las propuestas de diseño, considerando la normatividad para dispositivos médicos y con un enfoque de diseño para dispositivos de ablación durante laparoscopías abdominales

CT and MR Compatible Light Puncture Robot: Architectural Design and First Experiments

International audienceThis paper presents a new robotic architecture designed to perform interventional CT/MR procedures, particularly punctures. Such procedures are very popular nowadays for diagnostic or therapeutic purposes. Innovations concerning the robotic architecture, materials and energy sources are exposed. We also introduce the control loop we use to check the movements and the positioning of the robot, including a new method to localize the robot thanks to the images coming from the imaging devices (CT or MRI). Finally, the results of the first experiments are presented
