Definitions
- the present invention relates to an optical unit for flexible video side view duodenoscopes according to the preamble of claim 1.
- Nideo duodenoscopes are used in medical technology, where examinations or medical interventions are to be carried out inside the human body, particularly in the duodeno-papilla bile duct.
- the duodenoscopes are characterized, among other things, by the fact that optical images are transmitted from the inside of the body to the outside. Light is directed to the distal head end of the duodenoscope in order to close the areas to be examined. illuminate. Particularly in the case of duodenoscopes, an area to the side of the head is preferably illuminated or processed (side-view duodenoscope). The light reflected from these areas hits the side of the head, is from an optical
- This chip converts the light signals into electrical signals, which can be picked up and evaluated via a suitable connection at the proximal ends.
- Duodenoscopes are known from practice in which those reflected from the object
- the object of the invention is therefore to offer an optical unit which, with a smaller size, enables better image reproduction, is easier to clean and is less susceptible to contamination.
- the object is achieved by an optical unit according to claim 1.
- the invention is based on the knowledge that a shortening of the head length (in the longitudinal direction of the duodenoscope) is particularly advantageously possible if the CCD chip is arranged directly under the optical system, so that the im
- the chip is therefore not angled by a measure from the axial direction of the optical system, as was previously customary in the prior art, by a prism or the like.
- a deflection device is now superfluous.
- the optical system and the CCD chip form the essential components of the optical unit.
- the light signals that laterally enter the head and thus the optical system from the illuminated object are processed in it, for example by being passed through a lens package.
- the optical system is arranged essentially along an axial direction Z, so that the processed light signals also leave the optical system again along the axial direction Z.
- deflection losses are avoided, so that advantageously a better one Image quality can be achieved.
- the illuminated object, optical system and CCD chip are essentially on a straight line.
- the head of the duodenoscope on the one hand, is smaller overall due to the lack of a deflection device, and furthermore by the
- the CCD chip is no longer between the proximal end and the optical system, but rather at the same height as the optical system, so that the head is shorter by the length saved can be.
- the optical system is equipped with suitable lenses so that the captured light signals strike the CCD chip or its light-sensitive surface in a bundled or scattered manner.
- the image quality can be considerably improved by a suitable choice of the lens system without deflection losses or refraction effects due to the deflection device impairing this result.
- the optical unit is in one piece
- the optical unit can be formed particularly advantageously by gluing, screwing, latching or welding the components, in particular the optical system and CCD chip. Instead of these components directly, carrier elements can also be connected to one another, which in turn carry the components.
- the above-mentioned types of fastening result in particularly easy assembly
- the optical unit can be sealed against moisture in particular before the assembly, especially outside the head, which can be achieved by means of suitable adhesives, sealing elements and the like. In this way, the penetration of moisture into the optical unit, which is first assembled in the head, for example between the optical system and the CCD chip, can be avoided.
- a further advantageous embodiment of the invention provides that the optical unit can be inserted or removed into a largely complementary opening in the head (2). Placing the unit as a whole in the head simplifies it
- the entire unit can be inserted into the head in an axial plug-in movement, preferably in the Z direction. There it can be welded or glued to the head. Subsequent removal or replacement is also advantageously possible in a simple manner, since the angular construction of the optical unit required in the deflection device according to the prior art is omitted here.
- Different construction angles between the main longitudinal axis of the duodenoscope and the direction Z can also be realized particularly advantageously.
- only a different deflection angle of the prism could compensate for a changed arrangement of the optical system while maintaining the CCD chip arrangement in the head.
- the overall optical unit must therefore be changed. If you want to leave the CCD chip, deflection device and optical system unchanged in relation to each other, the head must be fundamentally redesigned, which is even less an option.
- the optical unit according to the present invention also allows different angles of incidence in a much simpler manner. Only the, for example, cylindrical recess in the head of the duodenoscope, in which the optical unit is inserted, must be provided differently in its position. In the new location and therefore at a new angle to
- the entire optical unit can be used along the main longitudinal axis of the duodenoscope.
- another area outside the head can be captured as an image.
- a further advantageous embodiment of the invention provides that the optical unit can be inserted, welded, locked or screwed into the opening of the head (2).
- a suitable process can advantageously be used here, with which in particular the tightness of the head against substances penetrating into the interior of the head is to be ensured.
- the area between the optical unit and the opening receiving it can be closed with sealant.
- the optical unit or its components can in particular consist of metal, glass, plastic or other materials suitable for medical technology.
- FIG. 1 shows in particular the head 2 of a duodenoscope 1.
- the exemplary duodenoscope head has a water channel 9 at its distal end.
- a light guide 6 is provided which enables the exit of illuminating light on the side of the duodenoscope head 2.
- a suction channel 4 is also indicated.
- the object illuminated by the light guide 6 reflects light signals L.
- the light signals L strike the optical system 3, which is formed essentially axially along a direction Z.
- the optical system has lenses and other optical elements which are suitable for bundling or filtering the light signals.
- a CCD chip 5 is arranged in the Z direction.
- the CCD chip 5 has a surface 7 on which the processed light signals L strike.
- the surface 7 is arranged essentially perpendicular to the axial direction Z, so that the light signals which come into the optical system 3 from the object at the top or exit from the top hit the CCD chip essentially perpendicularly.
- the signals converted in the CCD chip are then fed to the proximal end of the duodenos head (to the left in FIG. 1).
