Abstract
Description
Hierzu 1 Seite ZeichnungFor this 1 page drawing
Die Erfindung findet bei medizinischen Untersuchungen, vorzugsweise mit Stereomikroskopen und Kolposkopen, Anwendung.The invention finds application in medical examinations, preferably with stereomicroscopes and colposcopes.
Es ist bereits bekannt, das Licht einer Lichtquelle in Operationsmikroskopen und Kolposkopen über Lichtleiter an das Objektfeld heranzuführen (US 3 790 249). Dabei folgt der Lichtleiter meist im wesentlichen der Richtung des verwendeten Tragestativs, wobei das Lampengehäuse am oder im Stativ angeordnet ist (Zeiss „Kolposkop 99", Prosp.-Nr. 30-146-d, 1980; OPMl 99, Prosp.-Nr. 30-327-d, 1981).It is already known to introduce the light from a light source in surgical microscopes and colposcopes via optical fibers to the object field (US Pat. No. 3,790,249). In this case, the light guide usually follows substantially the direction of the support stand used, wherein the lamp housing is arranged on or in the stand (Zeiss "Kolposkop 99", Prosp.-No 30-146-d, 1980; OPMl 99, Prosp.No. 30-327-d, 1981).
Dabei ist der Lichtleiter teilweise im Innern des Stativarmes angeordnet. Einer der Gelenkarme des Stativs ist als Gehäuse ausgebildet und beinhaltet Lichtquelle und Stromversorgung.In this case, the light guide is partially disposed in the interior of the stand arm. One of the articulated arms of the tripod is designed as a housing and includes light source and power supply.
Bei der Außenverlegung von Versorgungskabeln an Operationsmikroskopen und Kolposkopen besteht prinzipiell die Gefahr des Hängenbleibens durch das Bedienpersonal. Dazu kommen Nachteile bezüglich der Reinhaltung.In the case of outdoor installation of supply cables to surgical microscopes and colposcopes, there is in principle the risk of the operator getting stuck. There are also disadvantages in terms of cleanliness.
Speziell bei Lichtleitern können durch Herausreißen, Knicken über scharfe Kanten und Erzeugung von unzulässig engen ' -'" Roschndigungen auftreten.Especially with light guides can occur by tearing out, kinking over sharp edges and creation of impermissibly narrow '-' "Roschndigungen.
Aus der US 3 776 614 ist es bereits bekannt, den Lichtleiter im wesentlichen im Stativinnern und durch die Gelenkpunkte der Stativarme zu führen.From US Pat. No. 3,776,614 it is already known to guide the light guide substantially inside the tripod and through the pivot points of the stand arms.
Da bei bekannten Lösungen der Lichtleiter fest mit der Lichtquelle bzw. dem Lichtaustritt verbunden ist, wird der Lichtleiter bei Verschwenkung des Gerätes um die entsprechenden Gelenkstellen stark auf Torsion beansprucht.Since, in known solutions, the light guide is firmly connected to the light source or the light exit, the light guide is strongly stressed upon torsion of the device to the corresponding articulation points.
Dadurch muß der Bewegungsbereich eingeschränkt werden, weil sonst der Lichtleiter zerstört werden könnte. Durch diese Einschränkung wird der Anwender stark behindert.As a result, the range of motion must be limited because otherwise the light guide could be destroyed. This restriction severely hinders the user.
Aufgabe der Erfindung ist es daher, eine Innenverlegung des Lichtleiters und dennoch eine anschlagsfreie Verschwenkung um mehrere Schwenkachsen zu ermöglichen.The object of the invention is therefore to allow an inner lining of the light guide and yet a stop-free pivoting about a plurality of pivot axes.
Die Aufgabe wird erfindungsgemäß bei einer gattungsgemäßen Anordnung durch die kennzeichnenden Merkmale des ersten Anspruchs gelöstThe object is achieved in a generic arrangement by the characterizing features of the first claim
Bevorzugte Weiterbildungen sind in den Unteransprüchen beschrieben. Preferred developments are described in the subclaims.
Die Erfindung wird nachstehend anhand der schematischen Zeichnung näher erläutert. Fig. 1: zeigt eine teilgeschnittene Seitenansicht eines Kolposkopes.The invention will be explained in more detail with reference to the schematic drawing. Fig. 1: shows a partially sectioned side view of a colposcope.
Das Gerät ist über einen festen Tragarm 1 drehbar und vertikal verschiebbar an einer Säule 2 aufgenommen, die z. B. an einem Bodenstativ oder einer Wandhalterung angebracht ist.The device is rotatable about a fixed arm 1 and vertically slidably received on a column 2, the z. B. is attached to a floor stand or a wall mount.
Der Tragarm 1 beinhaltet die Elektrik, eine Lichtquelle 3 sowie eine Lagerstelle 4 für die Drehachse 15 eines Parallelogrammtragarmes 5. Der Tragarm 5 ist mikroskopseitig als Lagerstelle 6 ausgebildet, in der eine Montierung 7 aufgenommen ist, die ein Stereomikroskop 8 trägt.The support arm 1 includes the electrics, a light source 3 and a bearing 4 for the rotation axis 15 of a Parallelogrammtragarmes 5. The support arm 5 is microscopically formed as a bearing 6, in which a mount 7 is received, which carries a stereo microscope 8.
An der Lagerstelle 4 kann eine Drehung des Parallelosrammtragarmes 5, an der Lagerstelle 6 eine Drehung der Montierung die vertikale Achse erfolaßn-De» stereomikroskop 8 kann um eine horizontale Achse 9 nach vorn und hinten geneigt werde: Das L'tehttter Lichtquelle 3 wird von einem Lichtleiter 10 über einen Kondensor 11, einen Umlenkspiegel 12 und ein Frontobjektiv 13 auf ein Untersuchungsobjekt 14 übertragen.At the bearing point 4 a rotation of the Parallelosrammtragarmes 5, at the bearing point 6 a rotation of the mount the vertical axis sucessn-stereomicroscope 8 can be inclined about a horizontal axis 9 forward and backward: The L'tehttter light source 3 is of a Optical fiber 10 via a condenser 11, a deflecting mirror 12 and a front lens 13 transmitted to an examination object 14.
Der Lichtleitereingang ist hierbei in der Drehachse 15 des Parallelogrammtragarmes 5 fest angeordnet und macht die Drehr des Tragarmes 5 um die vertikale Achse mit. Dadurch wird eine anschlagfreie Rundumdrehung von Tragarm 5 und Lichtleiter 10 ermöglicht. Der Lichtleiter 10 wird durch das Parallelogramm des Tragarmes 5, das Drehlager 6 sowie ein Schwenklager der Achse 9 hindurchgeführt und in der Montierung 7 mit seinem Ausgang in einem Wälzlager 16 aufgenommen. Durch diese Art der Aufnahme des Lichtleiterausganges kann die Montierung 7 mit Stereomikroskop 8 ut vertikale Achse gedreht werden, ohne daß der Lichtleiter 10 mitgeführt wird. Dadurch wird die Torsionsbeanspruchung г Lichtleiters 10 verhindert, und das Stereomikroskop 8 kann anschlagfrei um die vertikale Achse gedreht werden.The light guide input is in this case fixedly arranged in the axis of rotation 15 of the Parallelogrammtragarmes 5 and makes the rotation of the support arm 5 about the vertical axis. As a result, a stop-free all-round rotation of support arm 5 and light guide 10 is made possible. The light guide 10 is passed through the parallelogram of the support arm 5, the pivot bearing 6 and a pivot bearing of the axis 9 and received in the mount 7 with its output in a rolling bearing 16. By this type of recording of the light guide output, the mount 7 can be rotated with a stereo microscope 8 ut vertical axis without the light guide 10 is carried. As a result, the torsion stress г optical fiber 10 is prevented, and the stereomicroscope 8 can be rotated around the vertical axis without impact.
