Intravenous instrument, combination of instrument for inserting a needle into a body and image-forming system, processes for monitoring the alignment of an instrument with a visible beam of light and for providing accurate guidance along the pitch, and, device for penetrating a target sub-assume predetermined penetration angle.

摘要

The is an invasive instrument (400), such as a biopsy needle, syringe or drill.Adapted to be driven by an energy beam (66) such as a laser beam along a path line of sight pre - defined (65) in the direction of a target subsurface (50).The instrument is adapted for use in conjunction with a system of direct and shoot a beam of energy that directs a beam of energy in a stretch of line of sight in the sense dponsivo energyInterposed between the devices to access a target subsurface percutaneously and the conductive energy.And a positive process responsive to energy for a visual indication of alignment of the instrument with the directions of line of sight pre - defined,While moving the device for percutaneously accessing the target sub surface along the directions of line of sight towards the target.
