IÖ! 0 - KOLPOSKOP

Colposcopes for simple medical examination purposes and photocolposcopes are "already known.

Simple colposcopes, which have become known so far, have been constructed from binocular prism binoculars and a low-voltage light source "of weak luminosity has been placed above the binocular to illuminate the object. Such colposcopes are not suitable for photographic recordings. Only complicated apparatuses are known as photocolposcopes, which represent a combination of camera, binocular, weak light source and flashlight device. Medical examinations take place as with a simple colposcope, namely by looking through binoculars. A camera for photos is attached below the colposcope, with the image of the object through prisms and deflecting mirrors is passed over the binoculars to the lens of the camera. In IiLo the photograph management fires the flash with. Yerschlußöffnung the same time. Such devices are not only very complicated but also expensive.

The "photocolposcope" invention differs significantly from the previously known colposcopes.

The invention takes a completely new approach, namely the medical examination either only through binoculars, or directly to be able to carry out via a reflex camera, whereby in the second case the photographic recording directly during the examination using a special light source for artificial light photography is possible. The invention therefore not only represents a simplified problem in colposcope photography, but it opens up a new possibility in colposcope photography using existing phototechnical objects, The expensive and complicated mechanisms and optics of known photocolposcopes are inevitably eliminated. The invention consists in the fact that for colposcopy and photocolposcopy simply a light box with a bright, but by (transformer throttable projection lamp is used, over which a monocular or binocular binoculars can be attached. The light of The projection lamp is directed towards the object through a light tube and the light axis intersects with the optical axis of the binoculars on the object. The light intensity will vary depending on Demand regulated by a switch on the transformer (8). The projection lamp (18) is at the angle of inclination of the light tube (3) mounted and bundled by a lens located in the light tube. The binoculars, for the invention as a monocular shown, (1) is placed on the light box so that it is in the 4us millings provided in the form of the Binoculars fits. Is is made by an elastic or resilient

Strap (19) tightly stretched on the light box (2).

S ^{1 For} the simple examination, the user only needs to look through the ocular (7) and focus the binoculars in relation to the distance to the object. Binoculars (1) in connection with a light box (2), in which a projection lamp (18) is attached, represents the first idea of the invention for the photo colposcope to be applied. The second idea of the invention lies in the simplified problem of photo colposcopy in that simply attach a reflex camera to the light box using a suitable camera rail (5) and bring the lens so close to the ocular of the binoculars that the object can not only be viewed through the camera's shaft or prism finder, but also a photograph at the crucial moment can be done. The projection lamp chosen meets this requirement.

The third idea of the invention is that for handling A universal tripod is provided for the photocolposcope is, which is adjustable in height, in the horizontal and a swivel plate (1o) in a vertical angle, but at the same time it can be rotated horizontally through the extension tube (14), vrobei all such movements compensated for the purpose of precise horizontal and vertical axis position of the binoculars by a ball joint (12) can be.

The tripod rests on a tripod (17) in which a standpipe (16) is embedded. Stuck in the standpipe an extension tube (14) on which there is a loose adjusting ring (15). The extension tube can be higher or higher as required be set lower, the loose adjusting ring remains on a socket of the standpipe. At the desired height only the adjusting ring is tightened by means of a screw located on it, so that the standpipe does not slide any deeper can. Is can then be rotated in a circle until the standpipe is secured by means of a tommy screw at the end (K) is jammed against the extension tube. There is a swivel plate at the upper end of the extension tube. The fulcrum the swivel plate is located at the end of the in the extension tube inserted bolt, which in turn locks the swivel plate with a further tommy screw. This device enables the boom (11) to be pivoted in a vertical plane and at an angle of 9o °. With the swivel plate is a Guide tube (9) firmly connected. The boom (11) runs through this guide tube and can be limited on two sides be pulled out. The limitation is on the one hand through the transformer (8) and on the other hand through the ball joint (12) instead. The extension tube is locked in the desired extension length with a T-screw (K).

When all setting work on the tripod has been completed, the Light box by corresponding inclinations over the ball joint aligned, which then locks the desired position of the optical axes by means of a locking device (13). For the photo process then only needs-the camera on the Angle (5) = camera rail to be screwed, after which the rail by means of the retaining screw (4) on the light box

The perspective view shows that the boom runs through the guide tube (9), which in turn is connected to the pull-out tube (14) via the swivel plate (1o). The extension tube is in place in the standpipe (16) of the foot (17). A supply cable leads to the transformer and from the transformer second through the boom to the light box. !
