Description

Gegenstand der Erfindung sind weitere Ausbildungen des den Gegenstand des Patents 766 o59 bildenden Ruhigstellers. The invention relates to further developments of the subject of the patent 766 o59 constituting arrester.

Zum Ermöglichen eines bequemen Verstellens im Sinne eines Streckens des gebrochenen Gliedes sind mit den Enden der quer gerichteten-Schenkel des winkelförmigen Halters ungefähr in Richtung der in die Knochenenden einzuschiebenden Läg-sschenkel verlaufende Schraubenbolzen verbunden, die nach dem Einführen der Längsschenkel in die Knochenenden zusammen mit den Endteilen der Querschenkel von einem bügelförmigen Zwisdenstück aufgenommen werden, das zugleich als Widerlager für die Schraubenmuttern dient. Durch Anziehen der Muttern werden die winkelförmigen Halter entgegen dem Muskelzug auseinanderbewegt, so daß das gebrochene Glied gestreckt wird. To enable comfortable adjustment in the sense of stretching of the broken limb are with the ends of the transverse-limb of the angular Holder approximately in the direction of the Läg-thighs to be pushed into the bone ends extending screw bolts connected after the insertion of the longitudinal leg into the bone ends together with the end parts of the transverse leg of a bow-shaped Zwisdenstück are included, which also acts as an abutment for the screw nuts serves. By tightening the nuts, the angular brackets are turned against the Pull muscle apart so that the broken limb is stretched.

Die Zeichnung stellt ein Ausführungsbeispiel dieser Ausbildung des Gerätes dar. The drawing represents an embodiment of this training of the Device.

Fig. I ist teils eine Seitenansicht, teils ein Schnitt des ganzen Gerätes in der Gebrauchsstellung, Fig. 2 eine Endansicht des Zwischenstückes. lnl Fig. I sind mit 2 die beiden winkelförmigzn Halter, mit 2a deren in die Knochenbruchstücke I2 eingeführte Längsschenkel, mit 2b die durch eine Knochenlücke I2' nach außen tretenden Querschenkel bezeichnet. Letztere laufen in zweckmäßig stumpfwinklig zurückgebogene, also schräg zueinander stehende Schraubenbolzen 2 aus. Die zugehörigen Muttern 22 weisen in verstärkten zylindrischen Ansätzen 22' Ausdrehungen 23 auf. Fig. I is partly a side view, partly a section of the whole Device in the position of use, Fig. 2 is an end view of the intermediate piece. lnl Fig. I are with 2 the two angular holders, with 2a in the bone fragments I2 introduced longitudinal limbs, with 2b extending through a bone gap I2 'to the outside stepping transverse leg called. The latter run in appropriately bent back at an obtuse angle, so obliquely to each other screw bolts 2 from. The associated nuts 22 have recesses 23 in reinforced cylindrical lugs 22 '.

Zum Verbinden der Halter 2 an den Querschenkeln dient ein im Querschnitt rinnenförmiges Zwischenstück Ig, dessen halbkreisförmiger Boden in der Längsrichtung zur Anpassung an die schräg stehenden Bolzen 2e stumpf dachförmig verläuft. A cross-section is used to connect the holder 2 to the transverse legs channel-shaped intermediate piece Ig, whose semicircular bottom in the longitudinal direction to adapt to the inclined bolts 2e is bluntly roof-shaped.

Die Seitenwände des Rinnenstückes 19 fallen nach den Enden zu so weit ab, daß ihre Höhe hier nicht mehr ganz der Rinnenbreite entspricht. An den Enden sind nach lobten ebenfalls offenbleibende, im übrigen zylindrische Führungsansätze 20 gebildet, die in die Mutterausdrehungen 23 passen.The side walls of the channel piece 19 fall too far towards the ends from that their height no longer corresponds entirely to the width of the channel. At the ends are, according to praised, also remaining open, otherwise cylindrical guide approaches 20 which fit into the nut recesses 23.

Nach dem Einschieben der Längsschenkel 2a in die Knochenenden 12 wird das Zwischenstück 19 bei genügend weit zurückgeschraubten Muttern 22 über die Bolzen 2C und den äußeren Teil der Querschenkel 2b geschoben. Dann werden die Muttern 22 so weit angezogen, daß sie in den Ausdrehungen 23 der Ansätze 22' die Führungsansätze 20 des Zwischenstückes 19 aufnehmen. Zieht man nun die Muttern 22 noch weiter an, so ziehen sie, da ihnen das Zwischenstück 19 als Widerlager dient, die Bolzen 2c ein und damit die Halter 2 und die Knochenenden 12 gegen denMuskelzug auseinander. After the longitudinal legs 2a have been pushed into the bone ends 12 the intermediate piece 19 is screwed back sufficiently far back nuts 22 over the Bolt 2C and the outer part of the cross leg 2b pushed. Then the nuts 22 tightened so far that they in the recesses 23 of the lugs 22 'the guide lugs 20 of the intermediate piece 19 take up. If you now tighten the nuts 22 even further, so they pull, since the intermediate piece 19 serves as an abutment, the bolts 2c and thus the holders 2 and the bone ends 12 apart against the muscle pull.

Auf diese Weise kann man das gebrochene Glied strecken. Fehlt zwischen den Knochenenden I2 ein Knochenstück, wie es z. B. bei Schußverletzungen häufig der Fall ist, so kann man das Glied allmählich auf normale Länge bringen, wenn man, zweckmäßig nach Bildung des ersten Callus beginnend, entsprechend der weiteren Callusbildung die Schrauben allmählich anzieht.In this way you can straighten the broken limb. Missing between the bone ends I2 a piece of bone, as it is z. B. in gunshot wounds often is the case, the limb can gradually be brought to normal length if one, expediently starting after the formation of the first callus, corresponding to the further callus formation gradually tighten the screws.

Nötigenfalls kann das Gerät so lange angesetzt bleiben, bis die Knochenenden bereits durch Neubildung verbunden sind. Man muß es aber entfernen, solange die neue Knochenmasse noch nachgiebig ist, so daß man die Bruchstelle in eine das Herausziehen der Schenkel 2a ermöglichende schwache Winkelstellung bringen kann, um dann gegebenenfalls, wenn eine Deformierung nicht kurzzeitiges Anlegen einer Außenschiene verhindert werden kann, in den Knochenkanal noch eine Innenschiene einzuführen, die bis zur völligen Verfestigung der Knochenneubildung in Stellung bleiben kann. If necessary, the device can remain in place until the bone ends are already connected by new formation. But you have to remove it as long as the new bone mass is still pliable, so that you can pull the fracture point into a pulling out the leg 2a can bring a weak angular position enabling then, if necessary, if a deformation does not prevent an outer rail from being put on for a short time be able to insert an inner splint into the bone canal that extends up to the complete solidification of the new bone formation can remain in position.
