Abstract

The needle holder (3) for laparoscopic surgery has a cord guide (5) at its shaft end formed as a spring eye. The cord is held under light tension in the sprung eye. The shaft end is reduced to half a millimeter in size for attachment of the eye, which allows insertion of the needle holder into a trocar.

Description

Nadelhalter für laparoskopische Operationen sind chirurgische Instrumente, die üblicherweise aus einem Handgriff, einem 5mm-Durchmesser Schaft und den zwei Backen zum Fassen der Nadel bestehen. Die bisherigen Nadelhalter unterscheiden sich in Form und Material des Handgriffes und der Backen sowie in der Länge des Schaftes.Needle holders for laparoscopic operations are surgical instruments, commonly from a handle, a 5mm diameter shaft and the two jaws to grasp the needle. Differentiate the previous needle holders themselves in the shape and material of the handle and cheeks as well as in the length of the shaft.

Zum intraabdominalen Nähen und Knoten werden zwei Nadelhalter über je einen Arbeitstrokar (Innendurchmesser 5,5 mm ) in den Bauch eingeführt. Zum Knüpfen des Knotens wird mit einem Nadelhalter (1) das eine Fadenende (2) gefasst und dieser Faden doppelt um den geöffneten anderen Nadelhalter (3) geschlungen. Mit diesem Nadelhalter (3) wird nun das andere Fadenende (4) gefasst, durch die doppelte Schlinge gezogen und der Knoten festgezogen. In gleicher Weise werden nun zwei weitere Knoten in jeweils gegenläufiger Richtung gelegt.For intra-abdominal suturing and knotting, two needle holders are inserted into the abdomen via a working trocar (inner diameter 5.5 mm). To tie the knot, use a needle holder ( 1 ) one thread end ( 2 ) and this thread doubles around the opened other needle holder ( 3 ) looped. With this needle holder ( 3 ) now the other thread end ( 4 ) gripped, pulled through the double loop and the knot tightened. In the same way, two further nodes are now laid in opposite directions.

Wegen häufig enger anatomischer Verhältnisse und abhängig von den Trokareinstichstellen steiler Winkel der Nadelhalter zur Naht sowie wegen der Eigensteife des Nahtmaterials ist das Legen der Schlingen oft sehr schwierig oder gar unmöglich. Es besteht die Gefahr zusätzlicher Gewebeschädigung beim Patienten. Als laparoskopische Alternativen zur oben genannten Knüpftechnik gibt es bisher entweder das Knüpfen außerhalb des Bauchraumes und Vorschieben der Knoten mit einem Knotenschieber in den Bauch oder das Verbinden der Fadenenden mit speziellen Clips. Beide dieser Methoden sind aber nur beschränkt einsetzbar, so dass dann nur das Umsteigen auf eine konventionelle Schnitt-Operation bleibt.Because of the often tight anatomical relationships and dependent from the trocar insertion points to the steep angle of the needle holder Seam as well as due to the inherent stiffness of the suture material is laying the slings are often very difficult or even impossible. There is a danger additional Tissue damage at Patients. As a laparoscopic alternative to the above-mentioned knotting technique so far there is either knotting outside the abdomen and pushing the knots with a knot pusher in the belly or connecting the thread ends with special clips. However, both of these methods can only be used to a limited extent, so then only the change to a conventional cutting operation remains.

Dieses Problem wird mit der im Schutzanspruch 1 aufgeführten Fadenführung am Schaftende des Nadelhalters gelöst.This problem is with the protection claim 1 listed thread guide loosened at the shaft end of the needle holder.

Durch die Fadenführung (5) am Nadelhalter (3) wird nun die Richtung des Fadenendes (2) zum Nadelhalter (1) umgelenkt. In dieser optimalen Fadenposition gelingt das Legen der Fadenschlingen ohne Probleme.Through the thread guide ( 5 ) on the needle holder ( 3 ) the direction of the thread end ( 2 ) to the needle holder ( 1 ) redirected. In this optimal thread position, the thread loops can be laid without problems.

Eine vorteilhafte Umsetzung dieser Fadenführung ist im Schutzanspruch 2 durch den Einsatz einer Feder-Öse (6) angegeben. Der Faden lässt sich mit nur leichter Spannung in die Feder-Öse einführen und gleitet beim Knüpfen und Anziehen des Knotens problemlos aus der Feder-Öse heraus.An advantageous implementation of this thread guide is in the protection claim 2 by using a spring eyelet ( 6 ) specified. The thread can be inserted into the spring eye with only slight tension and slides easily out of the spring eye when the knot is tied and tightened.

Zum Anbringen der Feder-Öse wird das Schaftende im Durchmesser um 0,5mm verringert und auf der Oberseite abgeflacht. So gelingt ein problemloses Einführen des Nadelhalters durch den Arbeitstrokar.To attach the spring eyelet the shaft end reduced in diameter by 0.5mm and on the top flattened. This enables the needle holder to be inserted easily the work trocar.
