Medical instrument, in particular for percutaneous surgical/medical procedures

Abstract

A medical instrument, in particular for percutaneous surgical/medical procedures, including a handle portion designed to allow handling, orientation and manipulation of the medical instrument by an operator, and an elongated rod member secured to the handle portion. The elongated rod member extends from the handle portion up to a distal end. At least one portion of the elongated rod member, proximate to the distal end, is provided with a marking distinguishable under sonography. The marking is designed as a rotationally asymmetric marking configured to allow a location and a rotational orientation of the elongated rod member to be uniquely detectable in sonographic imagery. The marking includes first and second rotationally asymmetric markings extending in opposite directions along the elongated rod member.
