  Doppel-Stereomikroskop für chirurgische Zwecke 
 EMI1.1 
 

 <Desc/Clms Page number 2> 

   Körperhöhlender Beleuchtungsstrahlen dienenden Prismen 28, 28', deren den Objektiven zugewandte Flächen sphärisch geschliffen sind. Die Stereotubenpaare 20, 20' sind über je eine Feineinstellungsvorrichtung an den Träger 19 gekuppelt. Sie können unabhängig voneinander mittels der Drehknöpfe 29, 29' eingestellt werden. 



  Symmetrisch zwischen denObjektiven 27, 27' ist eine Kombination von Reflektoren 231 - 234 angeordnet, welche, wie ersichtlich, zwei miteinander verkitteten Glasprismen angehören. 



  Die Reflexionsflächen sind mit Spiegelbelägen versehen, welche einen zentralen Durchtritt 2 9 für die Strahlen freilassen. Wie schematisch angedeutet, werden die aus den Objektiven 27, 27' austretenden Achsstrahlen nach zweimaliger Reflexion in einem Punkt der Objektebene miteinander vereinigt. Mit den beiden Stereotubenpaaren 20, 20' ist je eine Beleuchtungsanordnung verbunden, deren jede durch ein rechtwinkelig geknicktesRohr 22. 22' zusammengefasst wird. Die von den Lichtquellen 30, 30' austreten- . den Strahlen werden durchKondensoren 31. 31' gebündelt und nachUmlenkung an den Prismen 32, 32' mit   
 EMI2.1 
 sie ein scharf begrenztes Leuchtfeld erzeugen. 



    PATENTANSPRÜCHE :    
1. Doppel-Stereomikroskop für chirurgische Zwecke, gekennzeichnet durch zwei an einem gemeinsamen, in der Höhe verstellbaren Träger symmetrisch angeordnete und über Feinverstellmittel angekuppelte Stereomikroskope mit schräg einander zugewandten Stereotuben   (20, 20'),   eine zwischen denselben vorgesehene Reflektorkombination   (23), cuber   welche die verlängerten Achsstrahlen der Objektive (27,   27') auch   bei grossem gegenseitigen Abstand derselben in einem Punkt der Objektebene vereinigt werden, sowie eine oberhalb   der Reflektorkombination vorgesehene Einrichtung   zur   Auflichtbeleuchtung   nach dem Köhlerschen Prinzip.

 EMI1.1
 

 <Desc / Clms Page number 2>

   Prisms 28, 28 'serving body cavity illuminating beams, the surfaces of which facing the lenses are spherically ground. The stereo tube pairs 20, 20 ′ are each coupled to the carrier 19 via a fine adjustment device. They can be set independently of one another by means of the rotary knobs 29, 29 '.



  A combination of reflectors 231-234, which, as can be seen, belong to two glass prisms cemented to one another, is arranged symmetrically between the lenses 27, 27 '.



  The reflective surfaces are provided with mirror coatings, which leave a central passage 29 for the rays. As indicated schematically, the axial beams emerging from the objectives 27, 27 'are combined with one another after two reflections at a point on the object plane. A lighting arrangement is connected to each of the two stereo tube pairs 20, 20 ', each of which is combined by a tube 22, 22' bent at right angles. The exit from the light sources 30, 30 '. the rays are bundled by condensers 31, 31 'and after being deflected by the prisms 32, 32' with them
 EMI2.1
 they generate a sharply delimited light field.



    PATENT CLAIMS:
1. Double stereomicroscope for surgical purposes, characterized by two stereomicroscopes symmetrically arranged on a common, height-adjustable carrier and coupled via fine adjustment means with stereo tubes (20, 20 ') facing each other at an angle, a reflector combination (23), cuber provided between them which the elongated axis beams of the objectives (27, 27 ') are combined in one point of the object plane even if the distance between them is large, as well as a device provided above the reflector combination for incident light according to the Koehler principle.

 

Claims (1)

2. Doppel-Stereomikroskop nach Anspruch 1, dadurch gekennzeichnet, dass die Lampentuben (22, 22') der Einrichtung zur Auflichtbeleuchtung doppelt, parallel und symmetrisch zur vertikalen Mittelebene des Gerätes sowie zweckmässig getrennt ein- und ausschaltbar vorgesehen und Umlenkreflektoren (32, 32') sowie 45 Prismen (28, 28') zugeordnet sind, mittels welcher die Beleuchtungsstrahlen oberhalb der Objektive (27, 27') in die Abbildungsstrahlengänge eingespiegelt werden. 2. Double stereo microscope according to claim 1, characterized in that the lamp tubes (22, 22 ') of the device for incident light illumination are provided twice, parallel and symmetrical to the vertical center plane of the device and can be conveniently switched on and off separately, and deflecting reflectors (32, 32') ) and 45 prisms (28, 28 ') are assigned, by means of which the illuminating beams are reflected into the imaging beam paths above the objectives (27, 27'). 3. Doppel-Stereomikroskop nach denAnsprüchen 1 und 2, gekennzeichnet durch eine Reflektorkombination (231-4)'innerhalb welcher die Beleuchtungs-und Beobachtungsstrahlengänge unter zweimaliger Strahlenkreuzung zweimal reflektiert werden. 3. Double stereomicroscope according to Claims 1 and 2, characterized by a reflector combination (231-4) within which the illumination and observation beam paths are reflected twice with two beams.
