Navigation of a medical instrument

Abstract

Invention of a device for the insertion of medical instruments into the human body.

1 . A device for inserting medical instruments into the human body, comprising a connected navigation system which monitors and guides the device, wherein the connected navigation system comprises at least three positioning points, wherein the positioning points can be distinguished from one another by different imaging methods, and wherein the device is monitored and guided under magnetic resonance radiological imaging.  
     
     
         2 . The device according to  claim 1 , further comprising a scaling for an instrument insertion channel, so that the solid angle can be measured and adjusted preferably starting from a hole center.  
     
     
         3 . The device according to  claim 1 , wherein the positioning of an inserted instrument is performed by a tilting, or a tilting and rotating motion, of one of the device parts.  
     
     
         4 . The device according to  claim 1 , wherein the tilting, or tilting and rotating motion, of a device part is effected by an actuation.  
     
     
         5 . The device according to  claim 1 , wherein the orientation of the inserted instrument is optically indicated or scannable by sensors directly at the device.  
     
     
         6 . The device according to  claim 1 , wherein the device is identifiable by navigations systems under radiological imaging in total or in parts.  
     
     
         7 . The device according to  claim 1 , comprising a plurality of attached, optically active or optically reflecting positioning points, which are monitored by a respective camera system, and wherein from the position of the attached, optically active or optically reflecting positioning points to each other, the position and orientation of the device can be calculated.  
     
     
         8 . The device according to  claim 1 , further comprising a resonator system having passive electro-technical parts.  
     
     
         9 . The device according to  claim 1 , wherein the device works as an actively sending system.  
     
     
         10 . The device according to  claim 1 , further comprising a number of volumes which are filled with a magnetic liquid wherein the magnetic liquid is positively or negatively identifiable.  
     
     
         11 . The device according to  claim 1 , wherein the device is manufactured of a material non-identifiable under radiological imaging, and wherein the device further comprises certain materials which are positively (actively) or negatively (passively) identifiable under radiological imaging attached at several points.  
     
     
         12 . The device according to  claim 6 , wherein the device is identifiable by navigation systems under magnetic resonance tomagraphy (MRI), in total or in part.
