Description
KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Der Gegenstand der vorliegenden Erfindung betrifft eine Antriebsvorrichtung für die Spreizarme von Dilatatoren, bei welcher die bisher üblichen Steuerringe vermieden sind.The object of the present invention relates to a drive device for the spreading arms of dilators, in which the previously common control rings are avoided.
Fig. ι und 2 zeigen Längsschnitte eines Diktators in geschlossenem und geöffnetem Zustande mit dem neuen Antrieb.Fig. Ι and 2 show longitudinal sections of a dictator in the closed and open state with the new drive.
Fig. 3 zeigt einen Schnitt durch den Antrieb nach C-D der Fig. 2,Fig. 3 shows a section through the drive according to CD of Fig. 2,
■Fig. 4 einen solchen nach E-F der Fig. 2, Fig. 5 einen solchen nach G-H der Fig. 2.■ Fig. 4 one according to EF in FIG. 2, FIG. 5 one according to GH in FIG. 2.
Der ganze Antrieb befindet sich in einer Hülse s. Die Bewegung der Spreizarme α erfolgt durch eine Schnecke z, welche in ein Zahnrad k eingreift, das fest mit einer Führungshülse / für die Spreizarme verbunden ist. Die letztere besitzt, wie Fig. 4 zeigt, an der Oberseite gekrümmte Schlitze m, in welchen sich an den unteren Enden der Spreizarme α befindliche Stifte η führen. Durch entsprechendes Drehen der Hülse / mittelst des Schneckentriebes z, k werden demnach durch die Bogenschütze m die Spreizarme α geöffnet oder geschlossen. The entire drive is located in a sleeve s. The expansion arms α are moved by a worm z, which engages a gear wheel k , which is firmly connected to a guide sleeve / for the expansion arms. The latter has, as FIG. 4 shows, curved slots m on the upper side, in which pins η located at the lower ends of the spreading arms α lead. By correspondingly turning the sleeve / by means of the worm drive z, k , the spreading arms α are accordingly opened or closed by the archer m.
Damit sich die Arme α stets geradlinig bewegen, ist unter der Hülse Z bezw. über den Schlitzen m eine mit der Aufsenhülse 5 fest verbundene Platte χ mit geraden Schlitzen 0 gelegt, in denen sich kantige Ansätze^ der Arme a ebenfalls führen.So that the arms α always move in a straight line, is under the sleeve Z respectively. Over the slots m a with the outer sleeve 5 firmly connected plate χ placed with straight slots 0, in which angular approaches ^ of the arms a also lead.
Die Einzelheiten der Bewegungsvorrichtung für die Spreizarme können auch in jeder anderen geeigneten Weise ausgeführt werden. Das Wesentliche ist der Schneckenantrieb an sich.The details of the movement device for the spreading arms can also be in each other be carried out in a suitable manner. The essential thing is the worm drive itself.
