DEVICE FOR GUIDING THE SYRINGE OF A USER SO AS TO ENABLE THE INJECTION OF THE ANALGESIC SOLUTION OF THE FORMER AS CLOSE TO THE MANDIBULAR FORAMEN AS POSSIBLE

摘要

The invention relates to a device for guiding the syringe of a user so as to enable the injection of the analgesic solution of the former as close to the mandibular foramen as possible during local-regional mandibular analgesia. Elements (1), (2), and (3) clamp the mandibular branch between the anterior edge (A) thereof that coincides with the end of element (2) and the posterior edge (P) that coincides with element (1), thereby determining the sagittal orientation thereof. In accordance with the curvature radius of element (4) centred on point O located about 1.5 cm from point P and in the direction of element (5) sliding perpendicularly to the tangents of element (4), all of the axes indicated by element (5) project onto the mandibular foramen point (O). The user places the syringe in the groove of element (5) and slides the former in order to select the axis which is located as high and as much on the side as possible in the oral cavity, and which makes it possible to reach the mandibular foramen (O), so as to prevent any abutment against the temporal crest. The device of the invention is particularly intended for dental surgeons and stomatologists performing regional mandibular analgesia.
