Problems solved by technology

The fourth type of recalibration device does have the advantage of being usable with 3D medical imaging systems due to the pyramidal shape of the radiopaque fiducial markers, but it also has an unacceptable disadvantage: the caregiver is exposed to radiation from the medical imaging system, which is increasingly unacceptable
However, any mechanical deformation of these soft tissues creat

Example Embodiment

[0061] The representation objects of the drawings show different aspects of several possible models, it is known that they are only given as examples, and the invention also covers other configurations. All these representations relate to the recalibration device 1 used during the acquisition of medical images of the patient's anatomical region 2 of interest. The anatomical area 2 of interest actually corresponds to the anatomical area 2 on which the surgeon performs surgery.

[0062] It should be noted that in the continuation of this document, the term reference system is used to denote the term "reference coordinate system".

[0063] During the acquisition of medical images, the use of the recalibration device 1 positioned at the height of the anatomical region 2 of interest allows the use of the reference frame of the three-dimensional digital model obtained from the medical image to recalibrate all reference frames of the elements involved in the future surgery . In other wo...

Abstract

The invention relates to a recalibration device (1) used during the acquisition of images of an anatomical area of a patient during robot-assisted surgery, including a body (3) made of radxoliacent material, which comprises fiducial markers (9) made of radiopaque material, said body {3) having a bearing surface (7) intended to be manually placed on a surface of said anatomical area of the patient.According to the invention, said fiducial markers (9) are arranged in a specific geometrical pattern enabling a certain detection of the positioning and orientation of the recalibration device (1) ina three-dimensional digital model built from the images derived from the acquisition of the anatomical area.

Description

technical field [0001] The present invention is in the field of robot-assisted surgery, and more particularly relates to robot-assisted surgery performed in complex anatomical regions, such as cerebrospinal surgery, in other words neurosurgery and / or spinal surgery. [0002] In this context, the present invention relates to a device and a method for recalibration between a frame of reference of a three-dimensional digital model obtained from medical pictures and a frame of reference of an anatomical region of a patient during robot-assisted surgery. In the continuation of this document, the data correspond to a specific coordinate system of the elements involved in the recalibration and / or surgical procedure. [0003] In this context, the recalibration device and recalibration method of the present invention allow matching the actual position of the patient's anatomical region with a three-dimensional digital model obtained from medical pictures of the patient's anatomical reg...
