Definitions

• TITLE Removable guide device for radiofluoroscopy infiltration with image intensifier.
• the present invention relates to a removable guiding device for infiltration under radiofluoroscopy with image intensifier.
• the displacement of the infiltration needle in the three planes of the space is visible only on a two-dimensional monitor through the image intensifier making the act not without technical failure and elongation exposure times, so irradiation.
• This technique uses a transparent radio table on which the patient is installed.
• the mobile hoop of the radiofluoroscope is mobilized and placed such that the field to be treated in the patient is between the X-ray tube and the image intensifier.
• the solicitation of the scopie pedal associated with the mobilization of the various articulations of the apparatus gives, on the reference monitor, the ideal image on a motionless patient.
• the puncture needle is handled at the same time as the scopic pedal, which gives, in real time on the monitor, the image of the needle on the chosen field with the anatomy bone of the region. solicited; the longer the examination, the more the patient and the examiners are exposed.
• the scope On some radiofluoroscopes, there is a fixed laser marker that gives the fixed skin mark. This mode is more useful for writing than for the scope.
• WO 2011 039 672 - Generating medical composite images has not made it possible to solve the problems identified contrary to the object of the present invention: Removable guiding device for infiltration under radiofluoroscopy.
• the present invention relates to a removable device adaptable to any mobile hoop with brightness enhancer for fluoroscopic radio guidance (-Planche I).
• a RADIO TRANSPARENCY GRIDAGE PARABOLE made of carbon fiber or any other transparent radio material, fixed on the image intensifier (b) such that the focal point is the X-ray focal point (c) and the space between it image intensifier of at least 5 cm to allow the manipulation of the radioopaque removable marker on the dome of the dish.
• the attachment device of the dish on the image intensifier is provided with a screw (d) allowing a lateral mobilization around the axis of the screw to remove it at any moment from the image field.
• mesh (j) (plate (II) are designed to receive the pedicle (f) of the radioopaque removable marker.
• This module has a side switch (n) and has at its base a magnetic ring (h) whose central hole (i) and designed to receive the pedicle (f) the radiopaque removable marker.
• the implementation of the intervention reduces the time of solicitation of the scopie pedal and radiation emission. It also allows, in the guidance procedure to materialize two parameters: the skin puncture point and the puncture direction in coaxial technique.
• Plate I - Represents the sectional diagram of the device of the invention.
• Plate II- represents in section the pellet above the parabola and opposite the laser pointer module.
• the double arrow indicates the direction of the attraction of the radio-opaque removable marker and laser pointer module through a hole in the parabola wire mesh.
