Abstract:
1. Medical instrument comprising: a guide tube insertable into a bodily passage of a patient, the guide tube having a closed inner axial guide channel internal to the guide tube which terminates in a lateral opening at the periphery of the guide tube behind the closed distal end of the guide tube and terminating with a deflecting channel comprising a guide channel in the shape of a wedged bevel or an arched curved ramp extending from a straight portion to said lateral opening and forming a continuous transition of the inner axial guide channel, the deflecting channel configured to cause an elastically flexible cannula proximally inserted into the guide channel to deflect when advanced in the guide channel and thereby emerge laterally at its distal tip through the opening at an angle to a longitudinal axis of the guide tube established by the deflecting channel; and a handle piece accommodating the guide tube at the proximal end of the guide tube, with the guide tube rotatable relative to the handle about the longitudinal axis of the guide tube in a rotatably guided manner, wherein the handle piece has a holder for a syringe in which the syringe is axially movable between a proximal position, in which the distal tip of its cannula is withdrawn in the guide channel, and a distal position in which the distal tip of the cannula emerges from the guide tube through the opening.
