Definitions
- the invention relates to an endoscope having a shaft, a main body arranged at the proximal end of the shaft, an eyepiece arranged at the proximal end of the main body, and a proximal end of the eyepiece
- Endoscopes are widely used in medicine and the arts to inspect hard to reach body cavities of a patient or areas of a machine and / or to make interventions in the corresponding body cavities or areas. While video-endoscopes with an integrated video camera are often used, endoscopes with an optical image conductor, which transmits an image picked up by a lens to an eyepiece on which it can be viewed with the naked eye or by means of an external camera, are widespread, especially in medicine. Such endoscopes, which are also referred to as optical endoscopes, can be made overall more slender and thus more patient-friendly than video endoscopes. Depending on the design and application of the endoscopes come fiber optics or lens image ladder used.
- Endoscopes typically have an elongate shaft which can be inserted into the cavity to be inspected.
- the shaft can vary depending on
- a main body is provided at the proximal end of the shaft.
- the main body is used to manipulate the endoscope and may also include ports through which fluids and / or instruments may be inserted or removed.
- the eyepiece is typically located at the proximal end of the main body and terminates in an eyepiece funnel.
- the eyepiece funnel was originally designed to comfortably fit the eye of a user, but is nowadays mostly used to set up an external camera on the endoscope.
- an object of the invention to provide a way to integrate an electronic component in the Okulartnchter of an endoscope.
- This object is achieved according to the invention by an endoscope with a shaft, an arranged at the proximal end of the shaft main body, arranged at the proximal end of the main body eyepiece, and arranged at the proximal end of the eyepiece Okulartnchter, which is further developed in that the
- Okulartnchter is composed of at least two parts, between which an electronic component is arranged.
- the electronic component can be easily integrated into the endoscope, without the basic structure of the
- Endoscope must be modified.
- Okulartrichters at least during assembly of the endoscope to be designed to be movable relative to each other.
- This allows a simple mounting of the endoscope, wherein first the electronic component is introduced between the parts of the eyepiece funnel, and these parts are then moved relative to each other into their final position.
- this aspect of the invention explicitly includes the possibility that the parts of the eyepiece funnel are connected during or after the assembly of the endoscope so that a movement of the parts to each other is no longer possible.
- a joint gap between the parts of the Okulartrichters after assembly by gluing, soldering or welding are sealed to prevent the ingress of moisture, dirt or germs in the Okulartnchter.
- the endoscope comprises an eyepiece system tube in which the eyepiece is arranged, and the electronic component is connected to an electronic circuit which is arranged inside the endoscope and outside the eyepiece system tube.
- a first part of the eyepiece funnel is screwed with a thread provided on the eyepiece system tube.
- a screw connection is simple and safe to manufacture.
- the eyepiece system tube of an endoscope according to the invention can protrude in sections into the main body, and be arranged around the non-projecting into the main body portion of the eyepiece system tube, a sleeve.
- a sleeve is often used to attach markings on the endoscope, and is therefore also referred to as a labeling sleeve.
- the sleeve can serve to ensure a predetermined geometric outer shape of the endoscope, while the position of the eyepiece system tube can be changed in an optical adjustment of the endoscope.
- a second part of the eyepiece funnel of an endoscope according to an embodiment of the invention can be screwed with a thread provided on the sleeve.
- connection between the electronic component and the electronic circuit to be made via a connecting element, which is arranged on the outside of the eyepiece system tube.
- the connecting element may, for example, solder pads, screw and / or
- the sleeve may have a passage window in the region of the connecting element. Through the passage window connecting wires of the electronic element can be performed.
- the through-window can be arranged with the sleeve fully assembled so that the connecting wires pass through the through-window
- the electronic component may comprise a coil.
- the electronic circuit can be an electrical consumer, for example a light source and / or a
- Window heating and / or an actuator and / or a video chip include.
- the endoscope 1 shows an endoscope 1 is shown.
- the endoscope 1 comprises a shaft 2 and a main body 3. Furthermore, the endoscope 1 comprises a at the proximal end of the
- Main body arranged eyepiece 4 with a Okulartrichter. 5
- FIG. 2 shows the proximal end of the endoscope 1 in detail.
- An eyepiece system tube 10 projects proximally out of the main body 3.
- optical components of the eyepiece 4 are arranged, which are not shown for clarity.
- the eyepiece system tube 10 terminates in an eyepiece window frame 1 1, in which an eyepiece 12 is sealingly inserted, for example by gluing or soldering.
- Eyepiece window frame made of a material whose thermal expansion coefficient corresponds approximately to that of the eyepiece 12.
- a material whose thermal expansion coefficient corresponds approximately to that of the eyepiece 12. for this purpose, for example, a steel of the type Sandvik 1 .4523 in question.
- a sleeve 15 is attached to the main body 3, which surrounds the eyepiece system tube 10.
- Proximal the endoscope is completed by the Okulartrichter 5, which is composed of two parts. A first, outer part 17 is screwed onto a thread 18 arranged at the proximal end of the sleeve 15. A second, inner part 19 is on an am Description proximal end of the eyepiece window frame 1 1 arranged threaded 20 screwed.
- the electronic circuit 28 can be used to process a signal captured by the electronic component 22, for example, to convert an AC signal received via a coil into a supply voltage for electrical consumers 30 arranged in the endoscope 1.
- the consumer 30 may be, inter alia, an electric light source, a window heater, an actuator and / or a video chip.
- the connector 26 is attached to the outside of the eyepiece system tube 10 and may include one or more solder pads or screw terminals.
- the eyepiece system tube 10 is first in the
- Main body 3 introduced, adjusted and then fixed. Then, the leads 27 of the electronic circuit 28 are attached to the connector 26. Subsequently, the sleeve 15 is placed on the main body 3 and fixed, for example by pressing. In this case, between the main body 3 and the sleeve 15 sealing elements
- the sleeve 15 is aligned during assembly so that a arranged in the wall of the sleeve 15 mounting window 32 is placed over the connecting element 26.
- the outer part 17 of the eyepiece funnel 5 is screwed onto the sleeve 15 and initially moved so far in the distal direction that the mounting window 32 is accessible proximally. Subsequently, the electronic component 22 is applied to the inner part 19 of the
- Eyepiece funnel 5 attached and the latter screwed onto the thread 20 of the Okularrome charged 1 1.
- the leads 25 are aligned in the direction of the sleeve 15. is Description of the inner part 19 firmly screwed to the eyepiece window frame 1 1, the electronic component 22 is oriented so that its leads 25 in the region of
- the outer part 17 of the eyepiece funnel is again screwed in the proximal direction so as to obscure the mounting window 32.
- the proximal edges of the parts 17,19 are aligned flush with each other, so that the Okulartrichter 5 has a flat proximal end surface.
- An annular gap 35 remaining between the parts 17,19 can be sealed by means of an adhesive in order to prevent the penetration of
- sealing elements such as O-rings, may be arranged between the outer part 17 of the Okulartrichters and the sleeve 15 to avoid the ingress of contaminants here as well.
