Abstract

The light conductor guide is used to house the light conductor, to protect it from damage, without exerting torsion on it. The light conductor extends between a light source (3) and the optical system of a microscope (8), eg. a stereo microscope, and is fed through the support system for the microscope. The light conductor is rotatable at one end, to prevent torsion being exerted on the light conductor upon rotation of the support arm (5). The light conductor output end is attached to the inner ring of a roller bearing, the outer bearing ring is attached to the microscope holder. ADVANTAGE - Allows unrestricted movement of microscope.

Description

Hierzu 1 Seite Zeichnung To this end, one side drawing

Die Erfindung findet bei medizinischen Untersuchungen, vorzugsweise mit Stereomikroskopen und Kolposkopen, Anwendung. The invention is used in medical examinations, preferably with stereo microscopes and colposcope, application.

Es ist bereits bekannt, das Licht einer Lichtquelle in Operationsmikroskopen und Kolposkopen über Lichtleiter an das Objektfeld heranzuführen (US 3 790 249). It is already known to introduce the light from a light source into surgical microscopes and colposcopes via light guides to the object field (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). In this case, the light guide usually substantially follows the direction of the support tripod to be used, wherein the lamp housing is arranged on or in the stand (Zeiss "colposcope 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. Here, the light conductor is partially arranged in the interior of the stand arm. Einer der Gelenkarme des Stativs ist als Gehäuse ausgebildet und beinhaltet Lichtquelle und Stromversorgung. One of the articulated arms of the stand is designed as a housing and includes a light source and power supply.

Bei der Außenverlegung von Versorgungskabeln an Operationsmikroskopen und Kolposkopen besteht prinzipiell die Gefahr des Hängenbleibens durch das Bedienpersonal. In the outdoor installation of utility cables to surgical microscopes and colposcope is basically the risk of getting caught by the operating personnel. Dazu kommen Nachteile bezüglich der Reinhaltung. There are also disadvantages in terms of pollution.

Speziell bei Lichtleitern können durch Herausreißen, Knicken über scharfe Kanten und Erzeugung von unzulässig engen ' -'" Roschndigungen auftreten. Especially in light guides can tearing, bending over sharp edges and production of inadmissible tight '-' "Rosh endings occur.

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 3,776,614 it is already known to cause the light guide essentially in the stand inside and through the pivot points of the tripod 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. As is firmly connected in known solutions the light guide with the light source or the light emission, the light guide in pivoting the device about the respective pivot points is greatly subjected to torsion.

Dadurch muß der Bewegungsbereich eingeschränkt werden, weil sonst der Lichtleiter zerstört werden könnte. Thus, the range of motion must be limited because otherwise the light guide could be destroyed. Durch diese Einschränkung wird der Anwender stark behindert. With this restriction, the user is severely hampered.

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 provide an inner lining of the light guide, and yet a non-impact pivoting about more pivot axes.

Die Aufgabe wird erfindungsgemäß bei einer gattungsgemäßen Anordnung durch die kennzeichnenden Merkmale des ersten Anspruchs gelöst The object is solved by the characterizing features of the first claim in a generic arrangement

Bevorzugte Weiterbildungen sind in den Unteransprüchen beschrieben. Preferred further developments are described in the subclaims.

Ausführungsbeispiel embodiment

Die Erfindung wird nachstehend anhand der schematischen Zeichnung näher erläutert. The invention will be further explained with reference to the schematic drawing. Fig. 1: zeigt eine teilgeschnittene Seitenansicht eines Kolposkopes. 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. The device is rotatable on a fixed bracket 1 and vertically slidably received on a column 2, z. B. an einem Bodenstativ oder einer Wandhalterung angebracht ist. B. is attached to a stand or a wall bracket.

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 electrical system, a light source 3, and a bearing point 4 for the rotational axis 15 of a parallelogram 5. The bracket 5 is formed microscope other as bearing point 6, in which a mount is added 7 which carries a stereomicroscope. 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. , A rotation of the Parallelosrammtragarmes 5 at the bearing point 4, rotation of the mount, the vertical axis erfolaßn-De "stereo microscope at the bearing point 6 8 can will tilted about a horizontal axis 9 to the front and rear: L'tehttter light source 3 is controlled by a light guide 10 via a condenser 11, a deflecting mirror 12 and a front lens 13 transferred onto an object to be examined fourteenth

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. The light guide input is in this case arranged in the axis of rotation 15 of the parallelogram 5, and makes the direction of rot of the support arm 5 about the vertical axis. Dadurch wird eine anschlagfreie Rundumdrehung von Tragarm 5 und Lichtleiter 10 ermöglicht. Characterized a non-impact circular rotation of the support arm 5 and the light guide 10 is made possible. 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. The light guide 10 is passed through the parallelogram of the support arm 5, the rotary bearing 6 and a pivot bearing the axis 9 and added to its output in a roller bearing 16 in the mount. 7 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. Through this type of receiving the light guide output, the mount can be rotated with 7 ut stereomicroscope 8 vertical axis, without that the light guide is carried along 10th Dadurch wird die Torsionsbeanspruchung г Lichtleiters 10 verhindert, und das Stereomikroskop 8 kann anschlagfrei um die vertikale Achse gedreht werden. Thereby, the torsional stress is г light guide 10 is prevented and the stereomicroscope 8 can be freely rotated velocity around the vertical axis.
