Problemproblem
Prostatakrebs ist mit weitem Abstand der am häufigsten diagnostizierte bösartige Tumor des Mannes. Eine erschreckend hohe und stetig steigende Zahl von neuen Prostatakrebs-Fällen in der westlichen Welt ist zu verzeichnen. In Deutschland erkranken pro Jahr etwa 25.100 Männer neu an Prostatakrebs. In der Statistik über krebsbedingte, organbezogene Todesursachen bei Männern rangiert er an zweiter Stelle.Prostate cancer is by far the most commonly diagnosed malignant tumor in the man. There is a shockingly high and steadily rising number of new prostate cancer cases in the Western world. In Germany, approximately 25,100 new men develop prostate cancer each year. In the statistics on cancer-related, organ-related causes of death in men, he ranks second.
Die Entscheidung, ob eine verdächtige Veränderung in der Prostatadrüse gut- oder bösartig ist, kann mit letzter Sicherheit nur durch eine Gewebeentnahme aus dem betreffenden Bezirk getroffen werden. Dies ist durch Tasten oder mit bildgebenden Verfahren wie Röntgen oder Ultraschall nicht möglich. Hierüber gibt nur die mikroskopische Untersuchung einer Gewebeprobe sicheren Aufschluss. Das Ergebnis der fachmännischen Begutachtung erlaubt die exakte Diagnose und eine entsprechende Behandlungsplanung. Um sicherzustellen, dass die Probe tatsächlich aus dem verdächtigen Bezirk entnommen wird, insbesondere wenn der Zielbereich nicht von außen sicht- oder tastbar ist, muss die Biopsie unter Kontrolle durch bildgebende Verfahren durchgeführt werden. Die Kernspintomographie liefert von einigen Körperregionen bessere Bilder als andere Methoden, sie ist besonders aussagekräftig in Körperregionen – wie der Prostata-Drüse, in denen viel Weichgewebe vorhanden ist. Aus medizinischer Sicht liegt also nahe, Biopsie und MRT miteinander zu kombinieren, um Diagnose, Lokalisierung und Therapie wesentlich zu verbessern.The decision as to whether a suspected alteration in the prostate gland is benign or malignant can only be made with the certainty of a tissue removal from the district concerned. This is not possible by keys or imaging techniques such as x-rays or ultrasound. This is only the microscopic examination of a tissue sample safe information. The result of the expert assessment allows the exact diagnosis and a corresponding treatment planning. To ensure that the sample is actually removed from the suspect area, especially if the target area is not visible or palpable, the biopsy must be performed under the control of imaging techniques. Magnetic Resonance Imaging provides better images of some parts of the body than other methods, and is particularly meaningful in areas of the body - such as the prostate gland, where there is a lot of soft tissue. From a medical point of view, it therefore makes sense to combine biopsy and MRI to significantly improve diagnosis, localization and therapy.
Zur Zeit werden Prostata-Biopsien zum größten Teil unter Ultraschall- oder unter palpatorischer Kontrolle durchgeführt, was zur Folge hat, dass eine exakte Gewebeentnahme aus der erkrankten Region sehr schwierig und oftmals ungenau ist, weil man mit der Nadel an der Probe vorbei sticht. Zum Teil werden nur einfache Quadranten untersucht bzw. Biopsien durchgeführt, bei denen ”blind” im entsprechenden Bereich der Prostata Gewebe entnommen wird.Currently, prostate biopsies are mostly performed under ultrasound or under palpatory control, with the result that accurate tissue removal from the diseased region is very difficult and often inaccurate because the needle is passed by the sample. In part, only simple quadrants are examined or biopsies performed, in which "blind" tissue is removed in the corresponding area of the prostate.
Bei den Prostata-Karzinomen handelt es überwiegend um kleine, sich langsam entwickelnde Tumoren, deren Bedeutung für den Krankheitsverlauf nicht zu unterschätzen ist. Im Kernspintomographen lassen sich auch kleine Läsionen sichtbar machen und bioptieren. Einige offene Kernspintomographen bieten die Möglichkeit, Biopsien im Sitzen oder in einer anderen Körperhaltung des Patienten durchzuführen, was den Zugang zur Prostata erheblich erleichtert. Die offene Kernspintomographie bietet dem Arzt zwar einen guten Zugang zum Patienten, jedoch noch zu geringe Flussdichten. Die konventionellen Kernspintomographen haben aufgrund ihrer höheren Flussdichte eine weit bessere Bildgebung. Wenn der Patient in der nur 60 cm großen Magnet-Röhre positioniert ist, stellt sich allerdings das Problem, dass die Prostata nicht so leicht erreicht werden kann, und der behandelnde Arzt keinen direkten Zugang zum Patienten hat.Prostate carcinomas are predominantly small, slowly developing tumors whose importance for the course of the disease should not be underestimated. Magnetic resonance imaging also makes it possible to visualize and biopsy small lesions. Some open magnetic resonance tomographs offer the possibility to perform biopsies while sitting or in a different posture of the patient, which considerably facilitates the access to the prostate. The open magnetic resonance tomography offers the doctor good access to the patient, but still too low flow densities. Conventional MRI scanners have far better imaging due to their higher flux density. However, if the patient is positioned in the 60 cm magnet tube, the problem arises that the prostate gland can not be reached so easily and the attending physician has no direct access to the patient.
Sinn und Aufgabe der hier vorliegenden Erfindung ist es, eine Vorrichtung zu konzipieren, die den Zugang zur Prostatadrüse für die Gewebeprobenentnahme und die Therapiefolge ermöglicht und die gestattet, auch bei geringen Platzverhältnissen in der konventionellen Kernspintomographie optimale Ergebnisse zu erzielen.The purpose and purpose of the present invention is to design a device that allows access to the prostate gland for tissue sampling and the treatment sequence and allows to achieve optimal results even in small spaces in conventional magnetic resonance imaging.

Beschreibung der Positionier- und HaltevorrichtungDescription of the positioning and holding device
Die Erfindung der Positionier- und Haltevorrichtung ist in den folgenden Figuren gezeigt:The invention of the positioning and holding device is shown in the following figures:
Der Patient befindet sich in Bauchlage, eine speziell geformte Lagerungshilfe
Die Nadel
Um den Bewegungsraum der Instrumente noch zu erhöhen, ist die Nadelführung wie in
In
Zwischen den Oberschenkeln des Patienten befindet sich die Haltevorrichtung
Jede Schicht der Prostatadrüse kann mittels dieser Positionier- und Haltevorrichtung mit einer Standard-Biopsienadel erreicht werden. Die Vorrichtung bietet die Möglichkeit, elektrische Antriebe in der Lagerungshilfe zu installieren, mit dem alle Freiheitsgerade einzeln gesteuert werden könnten. Der Antrieb erfolgt vorzugsweise über Ultraschallmotoren, die für den Einsatz im MRT modifiziert sind, aber auch entsprechend modifizierte Hydraulik oder Pneumatik ist möglich. Dabei können die Getriebe auch so ausgeführt werden, dass sie sich über Gestänge, flexible Wellen oder Seilzüge von außerhalb dem Magneten bewegen lassen. Dies kann sowohl rein mechanisch von Hand, oder auch automatisiert geschehen.Each layer of the prostate gland can be reached by means of this positioning and holding device with a standard biopsy needle. The device offers the possibility to install electric drives in the storage aid, with which all degrees of freedom could be controlled individually. The drive is preferably via ultrasonic motors that are modified for use in MRT, but also correspondingly modified hydraulics or pneumatics is possible. The gearboxes can also be designed in such a way that they can be moved from outside the magnet via rods, flexible shafts or cables. This can be done either purely mechanically by hand or automatically.
Wenn schwierige Punktionswege oder nicht penetrierbare Strukturen vorliegen, kann die Vorrichtung mit zusätzlichen Freiheitsgraden oder mit einer berechenbar biegsamen Biopsienadel ausgestattet werden.If there are difficult puncture or non-penetrable structures, the device can be provided with additional degrees of freedom or with a predictably flexible biopsy needle.
Ein anderes, nicht außer Acht zu lassendes Problem ist, dass die Nadel aufgrund unterschiedlicher Strukturdichte häufig nicht ganz gerade durch das Gewebe läuft, sondern vom geplanten Weg abweichen kann, oder gar die Läsion vor der Nadelspitze ausweicht. In diesem Falle wird die Ausrichtung der Biopsienadel notwendigerweise von der Vorrichtung schon während ihrer Platzierung korrigiert. Diese Korrektur erfolgt unter Echtzeitbildgebung, die Schnittebene wird durch die Sensoren an der Nadel oder Nadelführung korrigiert.Another not to be forgotten problem is that the needle often does not run quite straight through the tissue due to different density of structure, but may deviate from the planned path, or even evades the lesion in front of the needle tip. In this case, the orientation of the biopsy needle is necessarily corrected by the device already during its placement. This correction is done under real-time imaging, the cutting plane is corrected by the sensors on the needle or needle guide.
Die Vorgehensweise ist wie in dem hier beigefügten Flow Chart (
- 1. Die Grundplatte der Vorrichtung wird am Patiententisch fixiert.
- 2. Der Patient legt sich auf den Patiententisch; die Empfangs- eventuell auch Sendespulen werden fixiert.
