摘要:
The invention relates to an imaging system for following at least one surgical tool (5, 6) in an operation field inside a space (1) in the body of an animal, that comprises: at least one endoscopic camera (9) for obtaining endoscopic information of the operation field; at least one ultrasound imaging device (12) for obtaining ultrasound information on the operation field; an endoscopic and ultrasound information processing device (13), characterised in that it further comprises at least three markers (15, 16, 17) to be positioned in the operation field, said markers (15, 16, 17) being mobile relative to the tool (5, 6), and each marker being adapted to be captured both by the endoscopic camera (9) and the ultrasound imaging device (12) so that the processing means (13) can match the endoscopic information and the ultrasound information.

The invention relates to a device for guiding a medical needle, including said medical needle (1) and an insert (2) that is rotatably, translatably, and slidably arranged in the needle (1), wherein said device is characterized in that the insert (2) has, in the free state thereof, a curved distal portion (21), and in that the needle has at least two regions (11, 12), the mechanical behaviors of which are different, wherein the mechanical behaviors of each region (11, 12) and of the curved distal portion (21) of the insert are selected such that a movement of the insert (2) into the needle (1) causes a local deformation of the needle and/or of the insert. The invention also relates to a method for manufacturing said device.

The invention relates to a surgical procedure device, comprising a surgical instrument (1) capable of passing through human or animal tissues and a system comprising “passive” components capable of measuring a local stress or deformation of the instrument and/or “active” components capable of applying a local stress to the instrument, said system comprising at least two series (20, 21) of passive components arranged at the surface of the instrument in such a way as to establish a one-to-one relationship between the position of the instrument or the position of the distal end of the instrument and all the data derived from said series, and, as appropriate, at least two series (30, 31) of active components (3) arranged at the surface of the instrument. The invention also relates to a method for determining the position of the distal end of a surgical instrument capable of passing through human or animal tissues.
摘要:
The invention relates to a method for analysing a surgical operation by endoscopy in an operation field in a space inside the body of an animal, characterised in that it comprises the steps of: detecting at least one tool (1, 2, 3) present in the operation field; detecting at least one portion of an organ (4) in the vicinity of the detected tool (1, 2, 3); determining the position of the detected tool (1, 2, 3) relative to the detected organ (4) so that the detected tool (1, 2, 3), the detected portion of the organ (4) and their relative positioning form parameters defining a detected operation field; selecting, in a database, a conceptual field of operation corresponding to the detected operation field based on the detected tool (1, 2, 3), the detected portion of the organ (4), and their relative positioning; comparing the parameters of the detected field of operation with the parameters defining the selected conceptual field of operation in order to determine the deviations between said parameters; providing information on the quality of the detected field of operation based on the determined deviations.
