  • Biopsy is the targeted removal of a small tissue sample from a patient's body.
  • biopsy needles are generally used, the tip of which, after puncture, is advanced to the target volume in the tissue at a site of the body surface that is as close as possible to the tissue to be examined, where a tissue sample is then taken before the needle is removed again.
  • a mechanical needle guide is used which holds the biopsy needle and stabilizes it in a lateral direction so that a movement of the needle is only possible in an axial direction.
  • the actual needle guide opening is introduced into a guide head, which is freely movable over at least two degrees of freedom in a plane by certain distances.
  • An almost always occurring problem in biopsies is to reliably hit a target volume located inside the patient's body.
  • This is possible only with the use of an imaging method which images target volume and biopsy needle or needle guide and can visually represent their spatial relationship.
  • This method may be, for example, ultrasound, computed tomography or magnetic resonance tomography. Since the needle guide for reasons of imaging quality is made of largely transparent to the respective imaging process material, and the biopsy needle as an extended object difficult exact location, markers or pointers are used, which mark a reference point on the images.
  • the simplest procedure known from the prior art is to represent markers and target volumes on a picture with an image plane perpendicular to the puncturing direction.
  • An operator of the needle guide now only needs to position the needle guide head in such a way that markers and / or pointers are in line with the target volume. It is then guaranteed that a straight line along the direction from image focus to image point (s) of the target volume, ie substantially perpendicular to the image plane, must guide the needle tip through the target volume.
  • the further required depth information, ie the vertical distance between the trajectory of the needle guide head and the target volume can be determined from one or more additional images which are recorded in a plane not parallel to the first imaging plane. For the sake of simplicity, if possible, the first vertical image planes are usually selected. This makes the determination of the required distance particularly easy, since this can then be measured directly from this figure.
  • a disadvantage of this simple approach is that a puncture is not always possible directly or medically acceptable.
  • bones, cartilage or other comparatively hard tissue between direct injection site and target volume could be, the piercing with a biopsy needle hardly possible, or at least very imprecise, quite apart from the tissue traumata generated by such a biopsy.
  • It could also or additionally particularly sensitive tissue on the direct puncture path, such as blood vessels or nerve tracts, the piercing you want to avoid or must.
  • the direct puncture can be unnecessarily far through tissue.
  • needle guides are known from the prior art, which allow an additional pivoting of the needle guide head about one or two axes. Such needle guides are disclosed for example in DE 10 2013 1 13 277 A1.
  • the present invention therefore has the task of developing a biopsy needle guide, which allows a simple, fast, reliable and less error-prone Angulation without automation.
  • a biopsy needle guide according to the independent claim 1 which is used according to the invention according to independent claim 10.
  • the needle guide according to the invention is in this case simplified so far that angulation by an experienced operator without technical aids beyond the imaging method used to image the tissue to be examined is possible.
  • the design and ergonomics of the operation of the needle guide head were optimized as essential points. This works together in mutually beneficial ways to solve the task.
  • the head of the needle guide according to the invention is equipped with an opening for receiving a marker pin and can be moved in a plane and made pivotable about at least one axis.
  • the marker pen accommodates in its interior a marker part, which is sharply and contrastingly reproducible by the imaging method used.
  • the marker part forms a reference point on the basis of which the relative spatial position of target volume and needle guide head can be determined. In order to avoid a movement of this reference point, so the marker part of the marker from the trajectory of the head, the pivot axes of the head are in the trajectory and have a common
  • the marker pen is now constructed so that the marker part with its center comes as close as possible to this point of intersection.
  • the reference point formed by the marker part is independent of the swivel state, ie the selected swiveling angles, of the head and therefore remains stationary.
  • the advantageous inventive embodiment of the needle guide head At the beginning of the use according to the invention of this biopsy needle guide, the stationary placement and attachment of the needle guide is first of all above the body region of the patient to be examined. The needle guide head is then, if not done before, placed in a basic or starting position and the marker pin invention completely inserted into an opening of the head.
  • the images needed to determine the relevant information are created.
  • at least two images in different, non-parallel image planes are necessary, for example one perpendicular to a main direction and one containing this main direction. The main direction depends on the location of the region to be examined in the body.
  • the target position of the reference point in the traverse plane can be determined from the desired angular settings and the head can be moved to the appropriate position and swiveled as desired.
  • the marker pen is now replaced by a sterile adapter sleeve for guiding the needle and inserted the needle.
  • the needle tip When inserted into the body, the needle tip is advanced beyond the reference point as far as corresponds to the calculated distance between the reference point and the target volume. When this is done, the needle tip of the biopsy needle is in the intended target volume with very high confidence. The removal of a meaningful sample is thus possible.
  • x / x, zv - d tan (a,), where x is the ith coordinate, x ( zv is the value of the i-th coordinate for the target volume, d is the determined distance between the trajectory and the target volume and, which is the set angle relevant to the i-th coordinate.
  • the needle guide head of the biopsy needle guide according to the invention has a plurality of leadthrough openings, at least one of which is suitable for insertion of the marker pin according to the invention and another for inserting an adapter sleeve, these two openings each having an intersection with the pivot axis of the head.
  • the adapter sleeve and the marker pin each have similar and dimensioned shafts, so that they are compatible with the same openings. This allows you to freely choose which opening for receiving the
  • Marker pen which is to serve for receiving the biopsy needle. This can be usefully used, for example, for the left- or right-handed configuration of the needle guide according to the invention.
  • the marker part which accommodates the actual visual reference point and is housed in the marker pen, preferably has a cross-section or crosshair-shaped cross section. This allows, compared to a simple round or square cross section for the same area, a much more accurate visual localization of the reference point on the images produced by means of the imaging method used.
  • the marker part according to the present invention should ideally have such a cross-section not only in one but in two or even in three perpendicular planes. This ensures that the advantageously increased localization accuracy also comes into play for images whose image planes are not given by the main direction, but are essentially perpendicular thereto.
  • the marker part In order to ensure sufficient visibility of the marker part on the images, the marker part must be of sufficient size, which is why the diameter of the marker opening of the present invention is sufficiently large and chosen to be significantly larger than known from the prior art through-openings.
  • Marker pin a diameter, ie a shaft diameter, which is substantially larger than the diameter of a biopsy needle.
  • the diameter is 2-4 times that of a biopsy needle.
  • the present invention proposes to provide only a limited number of angle settings. It has proven particularly useful to provide the pivoting or the swiveled clamping of the needle guide head in discrete steps of 15 degrees.
  • a useful pivoting range here is from +30 to -30 degrees relative to a neutral position, in which the longitudinal directions of the openings of the head are perpendicular to the traversing plane. Particularly preferably, the pivoting range of +60 to -60 degrees.
  • the present invention also proposes preferred embodiments in which the head has two translational degrees of freedom that allow displacement in a plane. This is realized in such a way that the head can be moved on a guide carrier, which in turn is seated on a carriage which slides on a rail oriented perpendicular to the longitudinal direction of the guide carrier. Carriages such as head can be fixed in desired positions by fixing means, in particular clamping screws.
  • the head is particularly preferably fixed in the pivoted state, at least in discrete steps of 15 degrees between preferably -30 and +30 degrees, more preferably between -60 and + 60 degrees.
  • an embodiment with a plurality of openings is preferably used, so that the marker pen and biopsy needle can be used simultaneously.
  • the procedure described above would then have to be modified in such a way that when determining the travel position of the head, the known distance between reference point and adapter sleeve opening is taken into account, i. the head is then shifted by the appropriate distance. It is then no longer necessary to remove the marker pen until the needle is inserted and instead insert the adapter sleeve.
