Description

Vorrichtung zum Entfernen einer Krampfader, insbesondere einer Seitenastkrampfader Device for removing a varicose vein, in particular a side branch varicose vein
Technisches GebietTechnical area
Die Erfindung bezieht sich auf eine Vorrichtung zum Entfernen einer Krampfader, insbesondere einer Seitenastkrampfader, mit einem an einem Handgriff vorgesehenen Stiel, der an seinem stirnseitigen Einführende eine Arbeitskante zum Ablösen der Krampfader vom umgebenden Gewebe aufweist.The invention relates to a device for removing a varix, in particular a lateral spastic vein, having a handle provided on a handle which has a working edge for detaching the varicose vein from the surrounding tissue at its end-side insertion end.
Stand der TechnikState of the art
Bei der operativen Entfernung insbesondere von Seitenastkrampfadern wird im allgemeinen so vorgegangen, dass die zu entfernende Krampfader durch einen Hauteinschnitt vor die Haut gezogen und durchtrennt wird, um dann die Krampfader durch ein Ziehen und Drehen möglichst in einem Stück aus dem sie umgebenden Gewebe zu entfernen. Da die Zugfestigkeit der Krampfadern unter Umständen geringer als der Ausziehwiderstand ist, besteht die Gefahr, dass die Krampfader abreißt und stückweise entfernt werden muss, was zusätzliche Hauteinschnitte bedingt und die Operationszeit verlängert. Zur Verringerung des Ausziehwiderstandes der Seitenastkrampfadern wird daher häufig versucht, die zu entfernende Krampfader mit Hilfe eines Spatels vom umgebenden Gewebe zu lösen bzw. zu lockern. Da der Verlauf der Krampfader aber von außen nicht immer erkennbar ist, kann der durch den Hauteinschnitt gesteckte Spatel in solchen Fällen nicht genau geführt werden, sodass die Gefahr der Verletzung kleiner Nervenäste gegeben ist, was zu langwierigen Sensibilitätsstörungen in deren Versorgungsgebiet führen kann.In the surgical removal, in particular of lateral spastic veins, the procedure is generally such that the varicose vein to be removed is pulled through a skin incision in front of the skin and severed, in order then to remove the varicose vein as far as possible by pulling and turning it from the surrounding tissue. Since the tensile strength of the varicose veins may be less than the withdrawal resistance, there is a risk that the varicose vein tears and piece by piece must be removed, which causes additional skin incisions and extends the operation time. To reduce the Ausziehwiderstandes of the lateral spastic veins is therefore often trying to solve the varices to be removed with the help of a spatula from the surrounding tissue or to loosen. However, since the course of the varicose vein is not always visible from the outside, the spatula inserted through the skin incision can not be accurately guided in such cases, so that the risk of injury to small nerve branches is given, which can lead to protracted sensory disturbances in their supply area.
Dem Stand der Technik gehören außerdem Vorrichtungen an (DE 35 25 917 A1 , DE 197 54 779 A1 , FR 2 824 467 A1 , GB 2 195 540 A, US 2004/0215226 A1), die am stirnseitigen Einführende eines mit einem Handgriff versehenen Stiels einen Schneidring aufweisen, sodass die durch den Schneidring gezogene Krampfader mit Hilfe des Schneidringes freigeschnitten werden kann. Nachteilig ist allerdings, dass der Schneidring über den Stiel genau entlang der Krampfader geführt werden muss, um zu verhindern, dass die Krampfader frühzeitig durchtrennt wird. Dies bedeutet aber, dass der Verlauf der Krampfader möglichst genau bekannt sein muss, was im Allgemeinen jedoch nicht der Fall ist.The prior art also includes devices (DE 35 25 917 A1, DE 197 54 779 A1, FR 2 824 467 A1, GB 2 195 540 A, US 2004/0215226 A1), which have a cutting ring at the end-side insertion end of a handle provided with a handle, so that the pulled through the cutting ring varix with the help of the cutting ring can be cut free. The disadvantage, however, is that the cutting ring must be guided over the stem exactly along the varix, in order to prevent the varicose vein is cut early. However, this means that the course of the varicose vein must be known as accurately as possible, which is generally not the case.
Darstellung der ErfindungPresentation of the invention
Der Erfindung liegt somit die Aufgabe zugrunde, eine Vorrichtung der eingangs geschilderten Art zum Entfernen einer Krampfader, insbesondere einer Seitenastkrampfader, so zu verbessern, dass die Gefahr eines vorzeitigen Durchtren- nens gebannt werden kann, selbst wenn der Verlauf der zu entfernenden Krampfader nicht genau bekannt ist. Außerdem soll eine Verletzungsgefahr benachbarter Nervenäste tunlichst ausgeschlossen werden.The invention is thus based on the object of improving a device of the type described above for removing a varicose vein, in particular a lateral spasm vein, so that the risk of premature severance can be eliminated, even if the course of the varicose vein to be removed is not exactly known is. In addition, a risk of injury to neighboring nerve branches should be excluded as far as possible.
Die Erfindung löst die gestellte Aufgabe dadurch, dass der Stiel ein entlang der zu entfernenden Krampfader einführbares Rinnenprofil mit einer die vom umgebenden Gewebe abgelöste Krampfader aufnehmenden Profilrinne bildet.The invention achieves the stated object in that the stem forms a gutter profile which can be introduced along the varicose vein to be removed, with a trough groove which receives the varicose vein detached from the surrounding tissue.
Da das vorgeschlagene Rinnenprofil an seinem stimseitigen Einführende eine Arbeitskante zum Ablösen der zu entfernenden Krampfader vom umgebenden Gewebe bildet, die durch die Arbeitskante weniger freigeschnitten, sondern viel mehr freigeschabt wird, wird die zu entfernende Krampfader nicht nur mit Hilfe der Arbeitskante vom umgebenden Gewebe gelöst, sondern zugleich vom Rinnenprofil aufgenommen, das somit durch die zu entfernende Krampfader selbst geführt wird, sodass der genaue Verlauf der zu entfernenden Krampfader von außen nicht erkennbar sein muss, um das Rinnenprofil entlang der zu entfernenden Krampfader in einer Länge vorzuschieben, die dem zu entfernenden Krampfaderabschnitt entspricht. Es kann dabei in herkömmlicher Wei- se die zu entfernende Krampfader durch einen Hauteinschnitt vor die Haut gezogen und durchtrennt werden, bevor das Rinnenprofil mit Hilfe seines Handgriffes an die vor die Haut gezogene Krampfader angesetzt und bei festgehaltenem, abgeschnittenem Ende der Krampfader entlang dieser durch den Hauteinschnitt vorzugsweise unter einer Drehung um die Profilachse vorgeschoben wird. Danach braucht die Krampfader lediglich im Bereich des Einführendes des Rinnenprofils abgetrennt zu werden, um sie ohne Zugbelastung in einem Stück zusammen mit dem Rinnenprofil ausziehen zu können.Since the proposed gutter profile forms a working edge for detaching the varicose vein to be removed from the surrounding tissue, which is cut free by the working edge but much freed, the varicose to be removed is not only removed from the surrounding tissue with the aid of the working edge, but at the same time taken up by the gutter profile, which is thus guided by the varicose vein to be removed, so that the exact course of the varicose vein to be removed from the outside need not be recognizable to advance the gutter profile along the varicose vein to be removed in a length, which is the varicose vein segment to be removed equivalent. It can be used in conventional se the varicose vein to be removed are pulled through a skin incision in front of the skin and cut before the gutter profile by means of his handle attached to the pulled before the skin varicose and with held, cut end of the varix along this through the skin incision preferably with a rotation around the Profile axis is advanced. Thereafter, the varicose need only be separated in the region of the insertion end of the gutter profile in order to take them out without tensile load in one piece together with the gutter profile.
Besonders vorteilhafte Verhältnisse ergeben sich, wenn das Rinnenprofil im Bereich seines Einführendes eine die zu entfernende Krampfader umschließende Hülse umfasst, die eine umlaufende stirnseitige Arbeitskante bildet, sodass die zu entfernende Krampfader in ihrem gesamten Umfangsbereich sicher vom umgebenden Gewebe gelöst wird, wenn das Rinnenprofil mit der einführseitigen Hülse entlang der Krampfader vorgeschoben wird. Um das vor die Haut gezogene, abgeschnittene Ende der Krampfader nicht durch die Hülse fädeln zu müssen, kann das Rinnenprofil einen sein Einführende zu einer Hülse ergänzenden Hülsenabschnitt aufweisen, der auf das Einführende aufsteckbar oder um eine zur Hülsenachse parallele Schwenkachse auf dem Rinnenprofil schwenkbar gelagert ist. Bei einer solchen Ausführung des Rinnenprofils braucht das Rinnenprofil lediglich an die zu entfernende Krampfader angesetzt zu werden, um dann das Einführende des Rinnenprofils mit einem entsprechenden Hülsenabschnitt zu einer Hülse zu ergänzen, indem dieser Hülsenabschnitt entweder auf das Einführende aufgesteckt oder über das Einführende verschwenkt wird. In beiden Konstruktionsfällen ist darauf zu achten, dass die Schließstellung des Hülsenabschnittes entsprechend verrastet wird, um ein Lösen des Hülsenabschnittes während der Bewegung des Rinnenprofils entlang der Krampfader auszuschließen.Particularly advantageous conditions arise when the gutter profile in the region of its insertion end enclosing the varicose vein to be removed forming a circumferential end-side working edge, so that the varicose to be removed safely dissolved in its entire peripheral area of the surrounding tissue when the gutter profile with the Introductory sleeve is advanced along the varix. In order not to have to thread the drawn before the skin, cut end of the varix through the sleeve, the gutter profile may have an insertion leading to a sleeve sleeve portion which is mounted on the insertion end or pivotally mounted about a pivot axis parallel to the sleeve axis on the gutter profile , In such an embodiment of the channel profile, the channel profile only needs to be attached to the varicose to be removed, then to supplement the insertion end of the channel profile with a corresponding sleeve portion to a sleeve by this sleeve portion is either plugged onto the insertion end or pivoted about the insertion end. In both design cases, it is important to ensure that the closed position of the sleeve portion is locked accordingly to exclude a release of the sleeve portion during the movement of the gutter profile along the varix.

Fig. 1 eine erfindungsgemäße Vorrichtung zum Entfernen einer Krampfader in einer vereinfachten Seitenansicht, Fig. 2 diese Vorrichtung in einem achsnormalen Schnitt entlang der Linie H-Il der Fig. 1 in einem größeren Maßstab und Fig. 3 einen Schnitt nach der Linie Ill-Ill der Fig. 2.1 shows a device according to the invention for removing a varicose vein in a simplified side view, FIG. 2 shows this device in an axially normal section along the line H-II of FIG. 1 on a larger scale and FIG. 3 shows a section along the line III-III of Fig. 2.
Weg zur Ausführung der ErfindungWay to carry out the invention
Die dargestellte Vorrichtung zum Entfernen einer Krampfader, insbesondere einer Seitenastkrampfader, weist ein in einem Handgriff 1 eingesetztes Rinnenprofil 2 auf, das an seinem Einführende eine Hülse 3 bildet. Diese Hülse 3 setzt sich aus dem Rinnenprofil 2 und einem das Rinnenprofil 2 ergänzenden Hülsenabschnitt 4 zusammen, der an dem Rinnenprofil 2 um eine in Richtung eines Längsrandes des Rinnenprofils 2 verlaufende Achse angelenkt ist. Im Falle des Ausführungsbeispiels besteht das Rinnenprofil 2 aus Kunststoff, sodass das Gelenk zwischen dem Rinnenprofil 2 und dem Hülsenabschnitt 4 durch ein Filmscharnier 5 gebildet werden kann. Auf der bezüglich der Achse des Rinnenprofils 2 gegenüberliegenden Seite ist ein Verschluss 6 vorgesehen, mit dessen Hilfe der Hülsenabschnitt 4 mit dem Rinnenprofil 2 in der Schließstellung verbunden werden kann.The illustrated device for removing a varix, in particular a lateral spastic vein, has a groove profile 2 inserted in a handle 1, which forms a sleeve 3 at its insertion end. This sleeve 3 is composed of the channel profile 2 and the channel profile 2 complementary sleeve portion 4, which is hinged to the channel profile 2 about an axis extending in the direction of a longitudinal edge of the channel profile 2 axis. In the case of the embodiment, the channel profile 2 is made of plastic, so that the joint between the channel profile 2 and the sleeve portion 4 can be formed by a film hinge 5. On the opposite side relative to the axis of the channel profile 2, a closure 6 is provided, with the aid of which the sleeve section 4 can be connected to the channel profile 2 in the closed position.
Das Einführende des Rinnenprofils bildet eine Arbeitskante 7, wie dies der Fig. 3 entnommen werden kann. Diese Arbeitskante 7, die keine scharfe Schneide, sondern eine Schabkante bildet, verläuft am stirnseitigen Ende der Hülse 3 über den gesamten Hülsenumfang. Wird daher der Hülsenabschnitt 4 um eine zu entfernende Krampfader geschlossen, so kann das Rinnenprofil 2 mit der einführseitigen Hülse 4 entlang der Krampfader vorgeschoben werden, wobei die Krampfader vom umgebenden Gewebe in einfacher Weise gelöst wird, insbesondere wenn die Arbeitskante in einem beschränkten Ausmaß um die Achse des Rinnenprofils 2 hin- und hergedreht wird. Die Krampfader bildet dabei eine Führung für das Rinnenprofils 2, dessen Profilrinne die vom Gewebe gelöste Krampfader aufnimmt. Aus diesem Grunde empfiehlt es sich, den Durchmesser der Profilrinne an den Aderdurchmesser anzupassen.The insertion end of the channel profile forms a working edge 7, as shown in FIG. 3 can be removed. This working edge 7, which forms no sharp edge, but a scraping edge, extends at the front end of the sleeve 3 over the entire sleeve circumference. Therefore, when the sleeve portion 4 is closed around a varicose vein to be removed, the trough profile 2 can be advanced with the insertion side sleeve 4 along the varicose vein, the varicose vein being loosened from the surrounding tissue in a simple manner, especially if the working edge to a limited extent around the Axis of the channel profile 2 is rotated back and forth. The varicose vein forms while a guide for the channel profile 2, the trough receives the dissolved from the tissue varicose veins. For this reason, it is advisable to adapt the diameter of the trough to the core diameter.
Zur Entfernung einer Krampfader wird diese in herkömmlicher Weise durch einen Hauteinschnitt vor die Haut gezogen und durchtrennt. An das festgehaltene durchtrennte Ende der Krampfader kann das Einführende des Rinnenprofils 2 bei geöffnetem Hülsenabschnitt 4 angesetzt und der Hülsenabschnitt 4 um das Krampfaderende geschlossen werden. Es braucht danach lediglich das Rinnenprofil 2 mit Hilfe seines Handgriffes 1 entlang der Krampfader unter einem geringfügigen Hin- und Herdrehen durch den Hauteinschnitt vorgeschoben zu werden, um die Krampfader entlang ihres zu entfernenden Abschnittes vom umgebenden Gewebe zu lösen. Nach einem Durchtrennen der Krampfader im Bereich des Einführendes des Rinnenprofils 2 kann dann das Rinnenprofil 2 zusammen mit der in der Profilrinne befindlichen Krampfader ausgezogen werden. To remove a varicose vein, it is pulled in a conventional manner through a skin incision in front of the skin and cut. At the captured severed end of the varix the insertion end of the channel profile 2 can be set with the sleeve portion 4 open and the sleeve portion 4 closed around the varicose vein end. It only needs to be advanced then the gutter profile 2 with the help of his handle 1 along the varix with a slight back and forth rotation through the skin incision to release the varicose vein along its portion to be removed from the surrounding tissue. After severing the varicose vein in the region of the insertion end of the channel profile 2, the channel profile 2 can then be pulled out together with the varicose vein located in the profile channel.
