Abstract
The invention relates to a device for bringing into register for robotic surgery. The device having at least one insert designed to receive at least two distinct support elements, specifically a first support element having at least three marker elements disposed in a non-aligned spaced-apart configuration and made of a material that shows up in an image made with an appropriate imaging device; and a second support element having at least three energy-emitting or receiving elements likewise disposed in a non-aligned spaced-apart configuration. The invention serves to bring equipment for robotic surgery into register in a manner that is simple, safe, and reliable.
