Description

Prostata Immobilisations- und Positioniβreinrichtung für den Perinären ZugangProstate Immobilization and Positioning Device for Perineal Access
Die vorliegende Erfindung betrifft eine medizinische Immobilisations- und Positioniereinrichtung um Gewebeproben der Prostata Gland mittels Biopsienadeln durch den Perineum-Zugang des sich in Rückenlage befindlichen Patienten zu entnehmen.The present invention relates to a medical immobilisation and positioning device for taking tissue samples of the prostate gland by means of biopsy needles through the perineum access of the supine patient.
Es ist in der interventionellen Radiologie bekannt, Gewebeproben von verschiedensten Organen des Patienten mittels medizinischer Biopsieeinrichtungen zu entnehmen. Für die Biopsien der Prostata wird ausnahmslos der rektale Zugang gewählt, meist unter Kontrolle eines bildgebenden Verfahrens wie Ultraschall, selten Computer-Tomographie (CT) oder Magnet-Resonanz-Tomographie (MRT) .It is known in interventional radiology to take tissue samples from various organs of the patient by means of medical biopsy devices. For the biopsies of the prostate, the rectal approach is invariably chosen, usually under the control of an imaging technique such as ultrasound, rarely computerized tomography (CT) or magnetic resonance imaging (MRI).
Ein neuartiges Bildgebungsverfahren, die Magnet-Resonanz- Tomographie wird immer häufiger eingesetzt und es ist abzusehen dass dieses Bildgebungsverfahren auch für die Prostata-Diagnostik und Intervention eingesetzt wird. Diese Entwicklung ermöglicht für die Prostata-Biopsie alternativ zum rektalen Zugang den Zugang durch das Perineum (kleines Gebiet zwischen Anus und den Sexualorganen) zu wählen. Um diesem Umstand Rechnung zu tragen bedarf es einer neuartigen Prostata Immobilisations- undA novel imaging technique, magnetic resonance tomography is being used more and more frequently and it is anticipated that this imaging technique will also be used for prostate diagnostics and intervention. This development allows prostate biopsy as an alternative to rectal access to access through the perineum (small area between the anus and the sexual organs). To take account of this circumstance requires a novel prostate immobilization and
Positioniervorrichtung für den Perineum Zugang. Der rektale Zugang ist ein invasiver Eingriff und mit vielen Nebenwirkungen verbunden. Die Patientenposition in Kauerstellung ist für den Patienten sehr unangenehm und es fällt den Patienten schwer in der Position zu bleiben. Die Ruhigstellung ist für die Planung und Durchführung der Intervention sehr wichtig. Durch unbeabsichtigte Bewegung verliert man die bereits berechneten Einstichkoordinaten die notwendig sind für die präzise Gewebeprobeentnahme. Die Kauerstellung nimmt viel Platz ein und ist für den engen Tunnel des Computer-Tomographen oder Magnet-Resonanz- Tomographen ungeeignet. Die Prostata Immobilisations- und Positioniervorrichtung für den Perineum Zugang erlaubt eine für den Patienten angenehmere Position. Die Gewebeentnahme durch den Perineum Zugang ist patientenschonend und minimalinvasiv. Durch die kompakte Bauweise lässt sich die Prostata Immobilisations- und Positioniervorrichtung für den Perineum Zugang ideal in den engen Tunnel des Computer- Tomographen oder Magnet-Resonanz-Tomographen einführen.Positioning device for the perineum access. Rectal access is an invasive procedure with many side effects. The patient position in Chewing is very uncomfortable for the patient and it is difficult for the patient to stay in position. Immobilization is very important for the planning and implementation of the intervention. By unintentional movement one loses the already calculated puncture coordinates which are necessary for the precise tissue sample removal. The chewing position takes up a lot of space and is unsuitable for the narrow tunnel of the computer tomograph or magnetic resonance tomograph. The prostate immobilization and positioning device for the perineum access allows a more comfortable position for the patient. Tissue removal through the perineum access is patient friendly and minimally invasive. The compact design of the prostate immobilization and positioning device for perineum access makes it ideal to insert into the narrow tunnel of the computer tomograph or magnetic resonance tomograph.
Aufgabe der vorliegenden Erfindung ist es, in erster Linie mit einer neuartigen Immobilisations- und Positioniereinrichtung für die Gewebeentnahme mittels Biopsienadeln den Zugang zum Perineum des Patienten sicherzustellen und zugleich den Patienten stabil zu lagern.The object of the present invention is to ensure access to the perineum of the patient and at the same time to store the patient in a stable manner, primarily with a novel immobilization and positioning device for tissue removal by means of biopsy needles.
Diese Aufgabe wird bei der Einrichtung der eingangs definierten Art erfindungsgemäss durch die Merkmale des kennzeichnenden Teils von Anspruch 1 gelöst. Besonders vorteilhafte Ausführungsformen der Erfindung sind in den abhängigen Ansprüchen definiert!This object is achieved according to the invention in the device of the type defined by the features of the characterizing part of claim 1.

Dank der erfindungsgemässen Bauweise wird der Patient liegend in Rückenposition mittels Patientenauflage und Fixierungssystem stabil gelagert. Um unterschiedlichen Patientengrössen gerecht zu werden sind die Patientenauflage und das Fixierungssystem in verschiedenen Grossen erhältlich. Die Immobilisationsvorrichtung und die Positioniervorrichtung sind vorzugsweise mit einer gemeinsamen Basisplatte verbunden. Die Positioniervorrichtung ist mit einem Kontrastmittel enthaltenden Markierungsblock; ausgerüstet der mittels bildgebendem Verfahren sichtbar ist. Der Kontrastmittel enthaltende Markierungsblock dient der Planung der Gewebeentnahme mittels Biopsienadeln. DieThanks to the inventive construction, the patient is lying in the back position means patient support and Stable fixation system. In order to meet different patient sizes, the patient support and the fixation system are available in different sizes. The immobilization device and the positioning device are preferably connected to a common base plate. The positioning device is provided with a mark block containing contrast agent; equipped which is visible by means of imaging method. The contrast agent-containing marker block is used to plan the tissue removal by means of biopsy needles. The
Positioniervorrichtung enthält zudem eine Lochplatte welche der Positionierung und Führung der Biopsienadeln zur Gewebeentnahme der Prostata Gland dient. Dazu ist die Lochplatte in festen Winkeln um die horizontale Achse angulierbar. Zudem ist die Positioniervorrichtung in cranial-caudaler Richtung einstellbar sowie angulierbar in festen Winkeln um die vertikale Achse. Weil die Lochplatte aus Hygienegründen steril sein muss, ist sie ein steriler Einwegartikel. Die erfindungsgemässe Einrichtung ist kompatibel mit verschiedenen Oberflächenspulen und Biopsienadeln. Um die Kosten des Einwegartikels gering zu halten, ist sie z.B. in vier verschiedenen möglichen Positionen in der Positioniervorrichtung fixierbar.Positioning device also contains a perforated plate which serves to position and guide the biopsy needles for tissue removal of the prostate Gland. For this purpose, the perforated plate can be angulated at fixed angles about the horizontal axis. In addition, the positioning device is adjustable in the cranial-caudal direction and angulierbar at fixed angles about the vertical axis. Because the perforated plate must be sterile for reasons of hygiene, it is a sterile disposable article. The device according to the invention is compatible with different surface coils and biopsy needles. To keep the cost of the disposable article low, it is e.g. can be fixed in four different possible positions in the positioning device.

Beim Einsatz der Einrichtung wird der Patient in Rückenlage auf der Immobilisationsvorrichtung gelagert und mit dem Fixierungssystem immobilisiert. Die Positioniervorrichtung wird in die Nullposition eingestellt. Der Markierungsblock der mit Kontrastmittel gefüllt ist wird in der Positioniervorrichtung in der Nullposition fixiert und mittels bildgebendem Verfahren lokalisiert. Dazu scannen wir eine schnelle dynamische 3DTl Sequenz. Nach kurzer Zeit wird Kontrastmittel intravenös verabreicht um die Anreicherung des Kontrastmittels über die Zeit betrachten zu können. Nach dem wenige Minuten dauernden Scannvorgang wird erst der Markierungsblock als Referenz gesucht. Dies stellt den Nullpunkt des X-Y-Z Koordinatensystems dar. In einem weiteren Schritt wird die Läsion gesucht und es wird die relative Position der Läsion bezüglich des Nullpunktes bestimmt. Dies ist möglich entweder mit den bestehenden Softwaretools an der Konsole des MRT's oder CT' s oder mit einer geeigneten Kalkulationssoftware. Mit einer Kalkulationssoftware ist es möglich den Markierungsblock zu suchen, diesen Punkt als Referenzpunkt zu definieren, danach die Läsion zu suchen und diese auch zu definieren. Die Software berechnet anschliessend die Einstichstelle für die Biopsienadel und die Tiefe der Läsion in Bezug zu der X, Y und Z Achse. Es ist jetzt möglich mit Hilfe eines Koaxialsystems und einer Biopsienadel die Läsion zu biopsieren bzw. eine Gewebeprobe zu entnehmen. Mehrfache Gewebeentnahme ist möglich durch dass das Koaxialsystem im Gewebe bleiben kann und die Biopsienadel durch die Öffnung des Koaxialsystems ein- und ausgeführt werden kann. When using the device, the patient is stored supine on the Immobilisationsvorrichtung and immobilized with the fixation system. The positioning device is set to the zero position. The marker block filled with contrast agent is in the Positioning device fixed in the zero position and located by means of imaging process. For this we scan a fast dynamic 3DTl sequence. After a short time contrast agent is administered intravenously to be able to view the accumulation of the contrast agent over time. After scanning for a few minutes, the marker block is first searched for reference. This represents the zero point of the XYZ coordinate system. In a further step, the lesion is searched for and the relative position of the lesion with respect to the zero point is determined. This is possible either with the existing software tools on the console of the MRI or CT 's or with a suitable calculation software. With a calculation software it is possible to search the marker block, to define this point as a reference point, then to search for and define the lesion. The software then calculates the puncture site for the biopsy needle and the depth of the lesion relative to the X, Y, and Z axes. It is now possible with the help of a coaxial system and a biopsy needle to biopsize the lesion or to take a tissue sample. Multiple tissue removal is possible because the coaxial system can remain in the tissue and the biopsy needle can be inserted and exported through the opening of the coaxial system.
