The invention relates to a device for guiding a medical needle, including said medical needle () and an insert () that is rotatably, translatably, and slidably arranged in the needle (), wherein said device is characterized in that the insert () has, in the free state thereof, a curved distal portion (), and in that the needle has at least two regions (), the mechanical behaviors of which are different, wherein the mechanical behaviors of each region () and of the curved distal portion () of the insert are selected such that a movement of the insert () into the needle () causes a local deformation of the needle and/or of the insert. The invention also relates to a method for manufacturing said device.

In one embodiment of the present invention, a method is provided for assisting cartilage diagnostic and therapeutic procedures and includes the steps of acquiring 3D osteocartilaginous parameters by using multimodal 3D tracked devices; incorporating these parameters into a volumic anatomic osteocartilaginous model from which a bone tracking virtual real-time environment is built; three-dimensionally computing an osteocartilaginous quality score from this multiparametric 3D osteocartilaginous model; providing real-time navigation in this 3D virtual environment in order to make ongoing therapeutic assessments and adjustments; and updating steps 1 to 3 according to the performed therapy. It will be appreciated that the above steps are compatible with arthroscopic procedures involving cartilage.

Methods and apparatus for assisting cartilage diagnostic and therapeutic procedures

The invention concerns an analysis method for a surgical operation via endoscopy performed at an operative site in a volume located inside the body of an animal, characterized in that it comprises the steps consisting of:

System and method for analysing a surgical operation by endoscopy

The invention relates to an endoscopic imaging system for observation of an operative site () inside a volume () located inside the body of an animal, comprising:

Imaging system for three-dimensional observation of an operative site

The invention concerns an imaging system to monitor at least one surgical instrument in an operative site inside a volume of the body of an animal, comprising: at least one endoscopic camera to obtain endoscopic data on the operative site, at least one ultrasound imaging device to obtain ultrasound data on the operative site, and a processing device to process the endoscopic and ultrasound data. The imaging system further comprising at least three markers intended to be positioned in the operative site, said markers being mobile relative to the instrument, each marker being adapted to be detected both by the endoscopic camera and by the ultrasound imaging device, so as to permit cross-mapping of the endoscopic and ultrasound data by the processing means.

Imaging system for following a surgical tool in an operation field

The disclosure relates to a surgical intervention device, including a surgical instrument capable of passing through human or animal tissue and a system comprising so-called 'passive' components capable of measuring deformation or a local strain of the instrument and/or so-called 'active' components capable of imposing a local strain on the instrument, the system comprising at least two series of passive components arranged at the surface of the instrument so as to establish a biunivocal relation between the position of the instrument or the position of the distal end of the instrument and all the data originating from the series, and, where required, at least two series of active components arranged at the surface of the instrument. The disclosure also relates to a process for determining the position of the distal end of a surgical instrument capable of passing through human or animal tissue.
