Abstract
Description
Die Erfindung bezieht sich auf eine Fettabsauglanze zum Absaugen von Unterhautfett.The The invention relates to a liposuction lance for aspirating Subcutaneous fat.
Zum operativen Entfernen von Unterhautfett werden Fettabsauglanzen verwendet, die im wesentlichen aus einer Saugkanüle bestehen, die an ihrem distalen Endabschnitt eine oder mehrere Absaugöffnungen aufweist. Da das Absaugen des Unterhautfettes in vivo vorgenommen wird, ist geboten, Gefäße, Nervenbahnen etc., d.h. alle Bestandteile, die kein Unterhautfett sind, möglichst unversehrt zu erhalten. Beim Absaugen von Unterhautfett mit herkömmlichen Saugkanülen, die geradlinig ausgebildet sind, ist kaum zu vermeiden, dass durch die Absaugöffnungen auch Gefäße, Nervenbahnen und andere Körperbestandteile, die nicht Unterhautfett sind, abgesaugt werden.To the surgical removal of subcutaneous fat, liposuction lances are used which consist essentially of a suction cannula, which at its distal End section has one or more suction openings. Because the suction of the subcutaneous fat is made in vivo is required vessels, neural pathways etc., i. all components that are not subcutaneous fat, if possible to get intact. When aspirating subcutaneous fat with conventional suction cannulas, the are designed to be rectilinear, can hardly be avoided by the suction also vessels, nerve tracts and other body parts, which are not subcutaneous fat, are aspirated.
Aufgabe der Erfindung ist es demgegenüber, eine Fettabsauglanze zu schaffen, die ein gewebeschonenderes Absaugen ermöglicht.task the invention it is in contrast, a Fettabsauglanze to create a tissue-friendly suction allows.
Diese Aufgabe wird erfindungsgemäß mit den Merkmalen des Anspruches 1 gelöst.These Task is according to the invention with the Characteristics of claim 1 solved.
Gemäß der Erfindung ist der distale Endabschnitt der Saugkanüle zu einem Bogen gebogen und ist der proximale Abschnitt der Saugkanüle demgegenüber geradlinig ausgebildet. Die Absaugöffnung ist an dem distalen gebogenen Endabschnitt vorgesehen, und ist auf der der Axialen des geraden Abschnittes zugewandten Seite angeordnet, d.h. öffnet sich nach radial innen, nicht nach radial außen. Versuche haben ergeben, dass bei einer radial innenseitigen Anordnung der Absaugöffnung im Bereich des Saugkanülen-Bogens, insbesondere bei Schub- und Zugbewegungen der Fettabsauglanze, d.h. bei Bewegungen in axialer Richtung, die Gefahr, dass Gefäße und Nerven oder andere Gewebeteile, die nicht Unterhautfett sind, beschädigt werden, erheblich verringert ist.According to the invention the distal end portion of the suction cannula is bent into an arc and the proximal portion of the suction cannula on the other hand is rectilinear. The suction opening is provided at the distal bent end portion, and is on the side of the axial section facing the straight section, i.e. opens radially inward, not radially outward. Experiments have shown that in a radially inner side arrangement of the suction opening in Area of the suction cannula arch, especially during push and pull movements of the liposuction lance, i. When moving in the axial direction, the risk of vessels and nerves or other tissue parts that are not subcutaneous fat are damaged, is significantly reduced.
Der Bogen kann S-förmig ausgebildet sein, es können jedoch auch mehrere S-förmig oder auf andere Weise geformte Bögen vorgesehen sein. Der Bogen kann im einfachsten Fall aus einem einfach nach außen gebogenen Stück bestehen, weist jedoch bevorzugt mindestens einen Wendepunkt auf, so dass das distale Ende des bogenförmigen Endabschnittes nicht spitz, sondern stumpf in das Gewebe hineinragt.Of the Bow can be S-shaped be able to do it but also several S-shaped or otherwise shaped bows be provided. In the simplest case, the bow can be made from a simple to Outside curved piece but preferably has at least one inflection point, so that the distal end of the arcuate End section not pointed, but protrudes bluntly into the tissue.
Durch Vorsehen des Bogens am Endabschnitt wird es möglich, mit einer oszillierenden Rotationsbewegung der Saugkanüle mit dem Bogen eine mechanisch schälende Wirkung zu erzielen, mit der ein mechanischer Abtrag von Unterhautfett ermöglicht wird.By Provision of the arc at the end portion makes it possible with an oscillating rotational movement the suction cannula to achieve a mechanical peeling effect with the bow with which a mechanical removal of subcutaneous fat is made possible.
Der Bogen muss nicht kontinuierlich gekrümmt sein, sondern kann auch einen geraden Abschnitt aufweisen. Entscheidend ist, dass der Bogen einen exzentrischen Teil der Saugkanüle bildet.Of the Bow does not have to be continuously curved, but also can have a straight section. It is crucial that the bow one eccentric part of the suction cannula forms.
Die schälende Wirkung wird auch mit einer Saugkanüle realisiert, bei der die Absaugöffnung nicht radial innenseitig, d.h. auf der der Axialen des geraden Abschnittes zugewandten Seite, sondern radial außenseitig, angeordnet ist.The shelling Effect is also realized with a suction cannula, in which the Suction opening not radially inside, i. on the axial of the straight section facing side, but radially outside, is arranged.
Gemäß einer bevorzugten Ausgestaltung sind an dem Endabschnitt mehrere Absaugöffnungen vorgesehen, die alle auf der der Axialen des geraden Abschnittes zugewandten Seite, d.h. radial nach innen öffnend angeordnet sind. Es sind keine Absaugöffnungen vorhanden, die radial nach außen öffnen.According to one preferred embodiment are at the end of several suction openings provided, all on the axial of the straight section facing side, i. are arranged radially inwardly opening. It are no suction openings present, which open radially outward.
Vorzugsweise ist die Absaugöffnung bzw. sind die Absaugöffnungen in einem konkaven Teil des Bogens angeordnet. Hierdurch wird die gefäß- und nervenschonende Eigenschaft beim Absaugen von Unterhautfett noch verbessert.Preferably is the suction opening or are the suction openings arranged in a concave part of the arch. This will be the vascular and nerve sparing Property while sucking subcutaneous fat still improved.
Vorzugsweise ist ein angetriebener Rotations-Oszillator vorgesehen, der die Saugkanüle in eine oszillierende Drehbewegung versetzt. Die oszillierende Drehbewegung erfolgt um die Axiale des geraden Abschnittes herum. Durch die Begrenzung der Rotation auf eine Oszillation wird für den Fall des Einfädelns eines Gefäßes oder einer Nervenbahn die bei einer nicht-oszillierenden Rotation unvermeidliche Zerstörung vermieden. Da die manuelle Erzeugung einer rotatorischen Oszillation der Saugkanüle anstrengend ist, stellt der rotatorisch-oszillatorische Antrieb eine erhebliche Erleichterung dar. Der Oszillationswinkel und die Oszillationsfrequenz können vorzugsweise durch den behandelnden Arzt eingestellt werden.Preferably a driven rotary oscillator is provided, which the suction cannula in a oscillating rotational movement offset. The oscillating rotational movement occurs around the axial of the straight section. By the limitation the rotation to an oscillation is in the case of threading a Vessel or a nerve tract that avoids inevitable destruction in a non-oscillating rotation. Since the manual generation of a rotary oscillation of the suction cannula tiring is the rotatory-oscillatory Drive a considerable relief. The oscillation angle and the oscillation frequency can preferably be adjusted by the attending physician.
Gemäß einer bevorzugten Ausgestaltung ist ein angetriebener Axial-Oszillator vorgesehen, der die Saugkanüle in eine oszillierende Axialbewegung versetzt. Hierdurch kann der axiale Vortrieb der Saugkanüle im Unterhautgewebe erleichtert werden.According to one preferred embodiment is a driven axial oscillator provided the suction cannula placed in an oscillating axial movement. This allows the axial propulsion of the suction cannula be relieved in the subcutaneous tissue.
Vorzugsweise ist eine mit der Saugkanüle koaxiale Einspritzleitung und eine hiermit verbundene Einspritzöffnung am distalen Endabschnitt vorgesehen. Mit der Einspritzleitung kann durch die Einspritzöffnung eine Einspritzflüssigkeit in das das Unterhautfett aufweisende Gewebe eingespritzt werden. Die Einspritzung der Einspritzflüssigkeit kann gleichzeitig oder auch zeitlich versetzt zum Absaugen erfolgen. Die Einspritzöffnung kann an dem distalen Ende des Endabschnittes vorgesehen sein, kann jedoch auch radial innen oder radial außen im Bereich des Endabschnitt-Bogens vorgesehen sein. Die Einspritzöffnung kann düsenartig ausgebildet sein und schlitzförmig geformt sein, um auf diese Weise ein fächerartiges Strahlbild zu erhalten.Preferably, an injection line coaxial with the suction cannula and an injection opening connected thereto are provided at the distal end section. With the injection line, an injection fluid can be injected into the fabric having the subcutaneous fat through the injection opening. The injection of the injection liquid can simultaneously or also offset in time to Absau take place. The injection port may be provided at the distal end of the end portion, but may also be provided radially inward or radially outward in the region of the end portion arc. The injection opening may be formed like a nozzle and be slit-shaped, in order to obtain in this way a fan-like spray pattern.
