LOUIS & H. LOEWENSTEIN in BERLIN. Schiingenführer. LOUIS & H. LOEWENSTEIN in BERLIN. Sling leader.

Patentirt im Deutschen Reiche vom g. März 1899 ab.Patented in the German Empire by g. March 1899.

Der vorliegende Schiingenführer ist durch eine besondere Bewegungsvorrichtung für den Schiingendraht gekennzeichnet, durch welche eine sichere Bewegung der Schlinge ermöglicht und der Apparat gegenüber bekannten Apparaten mit Schlittenbewegung erheblich verkürzt wird. Der Operateur wird, falls er durch den Apparat hindurch eine Beobachtung anstellen will, nicht mehr durch die Schlittenführung behindert.The present loop guide is by a special movement device for the Shing wire, which enables the sling to move safely and the apparatus is considerably shortened compared to known apparatus with slide movement. The surgeon will, if he wants to make an observation through the apparatus, no longer through the slide guide with special needs.

Vorrichtungen mit Schlittenbewegung der Schlinge haben aufserdem den Nachtheil, dafs der Schiingendraht sich leicht in seiner Führung durch Seitwärtsbiegen festklemmt, so dafs man bei dünnen Drähten genöthigt ist, die an dem Schlitten befestigten Drahtenden durch übergeschobene Röhrchen zu verstärken, ein Aushülfsmittel, welches aber andere Uebelstände mit sich führt, indem das Durchführen der feinen Drähte durch die Röhrchen grofse Schwierigkeiten bietet Und jedenfalls von dem Operateur bei nothwendigem Wechsel des Drahtes kaum wird vorgenommen werden können. Das Auswechseln der Drähte, besonders während einer Operation, ist bei den meisten bekannten Schiingenführern überhaupt unthunlich.Devices with sled movement of the loop also have the disadvantage that the shing wire is easily clamped in its guide by bending sideways, so that with thin wires it is necessary to pass through the wire ends attached to the slide to strengthen tubes pushed over, a remedy, which, however, causes other inconveniences with it, since the fine wires are led through the tubes in a great way Difficulties are offered by the surgeon if it is necessary to change the Wire will hardly be able to be made. Changing the wires, especially during an operation, is with most known sling handlers at all impractical.

Bei dem vorliegenden Apparat ist eine sehr einfache und sichere Bewegung des Schiingendrahtes dadurch erzielt, dafs die Enden des Drahtes an nöthigenfalls getrennt drehbaren Scheiben derart befestigt sind, dafs sich der Draht beim Zurückziehen der Schlinge auf die Scheiben aufwickelt, beim Vorschieben aber abwickelt. Das Ausbiegen des Drahtes bezw. das Verlassen des Scheibenumfanges wird hierbei durch einen concentrisch um den Umfang der Scheiben gelegten Führungsbogen verhindert.With the present apparatus there is a very simple and safe movement of the loop wire achieved by the fact that the ends of the wire are attached to disks that can be rotated separately, if necessary, in such a way that the Wire winds up on the discs when the loop is withdrawn, when it is advanced but unwinds. The bending of the wire respectively. leaving the disc circumference is in this case by a guide arc placed concentrically around the circumference of the discs prevented.

Auf der Zeichnung ist der Apparat in Fig. 1 in Seitenansicht, in Fig. 2 in Oberansicht und in Fig. 3 im Schnitt nach der Linie A-A der Fig. ι dargestellt. Auf dem rohrförmigen Körper α des Apparates sind zwei Lagerböcke b angeordnet, in welchen die zur Bewegung des Schiingendrahtes c dienenden Scheiben d und e (Fig. 3) gelagert sind. Die Scheiben d und e sitzen auf verschiedenen Wellen/ und g (Fig. 2 und 3), von denen die Welle f durch die hohle Welle g hindurchgeht. In the drawing, the apparatus is shown in FIG. 1 in side view, in FIG. 2 in top view and in FIG. 3 in section along the line AA of FIG. On the tubular body α of the apparatus, two bearing blocks b are arranged, in which the disks d and e (FIG. 3) serving to move the loop wire c are mounted. The disks d and e sit on different shafts / and g (Fig. 2 and 3), of which the shaft f passes through the hollow shaft g .

Beide Wellen tragen Drehköpfe. h und f, welche durch eine Schraube h mit einander gekuppelt werden können, so' dafs man jede Scheibe einzeln oder beide zusammen drehen und die Scheiben auch verschieden zu einander einstellen kann. Die Bewegung der Scheiben d und e wird durch Anschläge / an den Lagerböcken begrenzt.Both shafts carry rotating heads. h and f, which can be coupled to one another by a screw h , so that each disk can be turned individually or both together and the disks can also be adjusted differently to one another. The movement of the disks d and e is limited by stops / on the bearing blocks.

An den Scheiben d und e werden die Enden des Schiingendrahtes c vermittelst Schrauben m oder auf andere Weise, befestigt und dann in am Umfang der Scheiben vorgesehene Rinnen eingelegt. Das Heraustreten der Drähte aus den Rinnen wird durch einen concentrisch die Scheiben d e umschliefsenden Führungsbogen η verhindert, welcher zwecks genauer Einstellung verschiebbar und leicht lösbar auf der Platte 0 befestigt ist. Die Feststellung des Bogens η erfolgt mittels der Schraube p. VonThe ends of the loop wire c are fastened to the disks d and e by means of screws m or in some other way and then inserted into grooves provided on the circumference of the disks. The emergence of the wires from the grooves is prevented by a concentric guide bow η enclosing the disks de , which is attached to the plate 0 in a displaceable and easily detachable manner for the purpose of precise adjustment. The arc η is determined by means of the screw p. from

Claims

the disks de the wire c is passed through the tube α to the beak q and here forms the loop r.

When the loop r is to be advanced or withdrawn, the two rotating heads h and i are coupled to one another by the screw k and the wire is wound onto or from the disks as the disks rotate.

The magnitude and shape of the discs de depends on the magnitude of the desired for the loop movement and you can full or, as shown, using segment-shaped slices.

If you want to cause a change in shape of the loop r , the same z. B. bend sideways, you release the coupling of the two disc shafts and you can now move each end of the wire separately, whereby the desired loop shape can be achieved, and this design inevitably happens, a preference that other devices in which the loop shape by loosening the one end of the wire is effected in the carriage and only moving the other, do not have. Working with the present device is therefore safer.

To feed a new wire, one need only remove the guide curve η and can then easily load a new wire into the groove in the disks de. If the loop is to be used as a warm loop, the two ends of the loop are connected to a power source and one of the disks d or e is isolated from the other, which can be done very simply by making one disk of insulating material Material, e.g. B. hard rubber manufactures. The guide curve η is also lined on the inside with insulating material.

In the illustrated arrangement of the sling apparatus, the two turrets hi to Bethätigung the discs de on the same side, namely, when viewed from the top of the apparatus, the right of same.

This arrangement has the disadvantage that one. Always operate the discs from one side only can.

As it happens very often in practice that the apparatus is used during the operation must be turned around, so the turning heads come on the left side, and the The surgeon is obliged to turn the head or heads with the left hand, which some do Presents difficulties and requires a certain amount of practice.

This deficiency is remedied in the embodiment of the apparatus shown in FIG. 4 in that the rotary heads hi are arranged on different sides of the disks de with a corresponding design of the axes. The inner axis f goes right through the hollow axis g and carries at its end an arm s in which the coupling screw k sits, which respectively in corresponding grains. Holes of the head h of the hollow axis g engages when coupling the two discs. With this arrangement, both discs can be operated from either side of the device and, if necessary, each disc can be rotated with one hand, whereby. as a result of using both hands, the sling shift is safer than using only one hand.

To form a magnitude noose on the windows wire length located not enough. Large loops of any size can now be obtained by wrapping the loop wire several times around one or both disks, so that the disks can be rotated several times and a correspondingly greater length of wire is unwound.

This embodiment of the sling guide is shown in FIGS. 5 and 6, and as an example an apparatus with only one disk is chosen, which is used to move one end of the loop, while the other is fixed by the disk t. You can of course also use two discs.

The movable end of the loop wire is placed around a round disk u , which has a screwed screw groove ν on its circumference, which is used to hold the wire c .

A guide ring w is placed around the disk u , which, like the arc η, prevents the wire from jumping off the disk. The ring has a slot x for the wire to exit.

In order to achieve the wire always DAF at the same place the disk & verläfst and the direction thereof to the guide tube a always remains the same, the axis y is threaded%, the pitch of that of the thread on the circumference of the disk u is equal. The corresponding nut thread is located in the bearing block b, and as a result of this arrangement, the disk u is laterally displaced by one pitch of the screw with each revolution.
