Description

 endoscopy device

The invention relates to an endoscopy device, comprising an endoscope, wherein the endoscope has an endoscope tip which can be moved via tension elements from a location remote from the endoscope tip in two mutually perpendicular directions.

For diagnostic and therapeutic examination interventions flexible endoscopes of the type mentioned are used, which are well known in the art. They are introduced rectally or orally and pushed to the point to be examined or along the area to be examined, z. In the area of the colon (colonoscopy), the duodenum, the stomach (gastroscopy) or the esophagus. The direction control of the movable endoscope tip in two planes is carried out mechanically by means of two actuators in the form of handwheels (control wheels) on the endoscope handle in order to minimize lumenzentriert and the intestinal wall gently pretend or optimally set a target region. The feed or the backward movement of the endoscope can be carried out manually, wherein a hand of the examiner must release the control wheels on the endoscope handle in order to grasp and advance the endoscope shaft.

CONFIRMATION COPY In order to be able to work more safely or more efficiently in this regard, it has become known from DE 10 2005 002 461 B3 to use an electric endoscope drive. By means of a pedal, a forward or backward movement of the endoscope can take place, which already allows improved handling during the operation.

For both diagnostic and therapeutic applications it is necessary to have additional functions available. An essential function is the tissue removal, for example by means of an electric sling (electro-cutting function or coagulation). For this purpose, the electric loop is advanced through the endoscope into the intestine or the stomach and placed around the tissue to be removed. By applying a high frequency current then the tissue removal can take place. In order to leave the hand on the endoscope handle for this purpose, the surgeon operates this another pedal, which causes the power supply.

A similar feature that is always needed is the image documentation. Here, the intestine or the stomach is observed by means of a camera in the endoscope head and displayed on a screen. When the camera is in the appropriate position, the operator operates an appropriate footswitch to save the image seen by the camera. The same applies to other functions, such. B. for rinsing the site to be examined or operated on.

In an advantageous manner, the surgeon can thus optimally handle the endoscope since he does not have to release the control wheels of the endoscope. In order to make the exact setting of the endoscope tip, the two handwheels on the endoscope handle must each be moved to a defined rotational position. This makes it necessary that two setting operations - one for each handwheel - are made. For this purpose, the surgeon usually requires both hands. Accordingly, it is the surgeon at least for the period of adjustment of the endoscope tip not possible to make by hand another required operation to perform any of the above measures. For this purpose, the intervention of an assistant is required.

Also important in the colonoscopy is the back mirroring, as in this phase of the investigation, the findings are collected. One problem in this context is the relatively high rate of missed findings at up to 14%. Therefore, as a recommendation or as a guideline is given that the mirroring should last at least six minutes.

Furthermore, it is remarkable that the surgical options for endoscopic procedures and thus also for colonoscopy are becoming more and more demanding and complex.

It has therefore become known from DE 20 2010 009 234 Ul to equip the endoscope with a receptacle for releasably fixing the handle. In this case, two coupling elements (in the manner of a hubcap) are provided, which can be releasably brought into rotationally fixed engagement with one of the hand wheels of the endoscope. Further, two rotary actuators are provided, which are each in rotary connection with a coupling element and which are connected to a controller. The control element communicates with a controller, wherein it is formed, depending on the position of the control element to move the rotary actuators in a defined rotational position. This makes it possible to make commercially available endoscopes for explained automated operation suitable. It can also be provided that the transmittable torque between said "hubcaps" and the handwheels are set to maximum limits, so that injuries to the intestinal wall have been imposed and damage to the endoscope can also be avoided.

The above-mentioned solution according to DE 20 2010 009 234 U1 in this respect already represents a considerable improvement over "hands-free" endoscopy, especially in combination with an endoscope feed device, and can be used more efficiently and with less use of personnel Device box integrated and the operation clear and easy to reach in the hand area of the console realized, the many disturbing footswitch omitted.

When using commercially available endoscopes that can be clamped in the console, it is advantageous that you can work immediately with the usual and available in the departments endoscopes and this can be processed as before in the washing machine (handling / processes / environment as before ). Also, in the transition or learning phase, the endoscope can be quickly removed from the holder at any time in order to be able to endoscopically condense in the short term in the event of still unfamiliar maneuvers or passages.

However, the disadvantage of using conventional endoscopes in the known device is the following: The mechanical coupling to the control wheels of the endoscope handle to different types of endoscopes must be adapted (different "hubcaps"). This results in a cumbersome and complex construction of the console used.

Conventional endoscopes are becoming increasingly expensive and require a large and unwieldy device tower. The screen is usually mounted on the tower and not positioned directly in front of the surgeon. The commonly used optical fiber technology ages rapidly (the fibers become blind over time). The light supply via the conventional fiber optic cable requires a separate device or processor.

The cables are prone to repair, the working channel is leaking. The essay or the accessibility of the working channel is different and must be adapted, in part, a cumbersome work is given.

Sometimes the endoscopes are not long enough with difficult bowing.

The endoscope reprocessing in the washing machine is complicated and expensive, which requires that several endoscopes are needed because there is always one in the washing machine. The invention is therefore based on the object, a Endoskopier- device of the type mentioned in such a way that in this regard an improvement is achieved. Accordingly, it should be possible to find a more cost-effective solution while still fully preserving the functionality of the endoscope. Nevertheless, it should be possible in particular During the endoscopic examination, the surgeon should keep his hands as free as possible in order to maintain a high level of diagnostic safety and to ensure the precision of the examination or operation. It should therefore be proposed a concept with which a simplified and cheaper realization of the endoscope is possible. Furthermore, the aim is to provide a modular endoscope designed as possible, which makes it possible to provide the required functionality via suitable interfaces, in particular with regard to the recording of images and their evaluation, with a cost-effective solution is sought, with a minimum number on replaceable components.

The solution to this problem by the invention is characterized in that the tension elements emerge from an end region of the endoscope, wherein each tension element is connected to a movement device, with which the tension element can be moved in the longitudinal direction of the endoscope.

It is very advantageous if it is provided that in the end region of the endoscope at least one supply or optical cable and at least one electric cable emerge from the endoscope, which are guided to a processor, wherein the supply or optical cable for supplying electricity or light to the endoscope tip is formed and wherein the electric cable is designed to supply a camera signal to the processor.

The at least one supply or optical fiber cable or the at least one electric cable is preferably connected via a detachable plug connection directly or indirectly to the processor. Especially Preferably, however, it is provided that the at least one supply or optical cable and / or the at least one electric cable are connected via a detachable plug connection with an adapter, wherein the adapter is connected to the processor. The adapter preferably comprises processing electronics with which the signal transmitted via the supply cable or optical fiber cable and / or the signal transmitted via the electric cable for the illumination can be processed via the endoscope tip and / or for the image evaluation in the processor. The at least one supply or optical fiber cable and / or the at least one electric cable are preferably connected via a detachable plug connection with the end portion of the endoscope.

With respect to the formation of said movement device is preferably provided that in each case two tension elements which correspond to a direction of movement form a loop, each loop is guided around a disc or annular control element, wherein the disc or annular control element with a rotary drive in communication stands. The controls are preferably designed as wheels, which are connected via a drive means with an electric motor, in particular a servo motor in combination. The drive means are preferably toothed belts. The controls are preferably free of a cover. The tension elements thus emerge freely from the axial end of the endoscope and are looped around the controls (wheels).

Between the end region of the endoscope and the control elements, means are preferably arranged with which the distance in the longitudinal direction of the endoscope can be adjusted. These agents preferably include Spring element, with which a resilient bias between the end portion of the endoscope and the controls - again in the longitudinal direction of the endoscope - can be generated and maintained. The endoscope may include at least one working channel extending in the longitudinal direction of the endoscope to the endoscope tip.

The endoscopy device may further comprise means for controlled or axial axial advancement of the endoscope in its longitudinal direction; From the above-mentioned prior art, such a device is known as such.

The rotary actuators may be in communication with a control device, wherein the control device for the combined actuation of two rotary drives comprises a joystick.

The controls are preferably arranged concentrically to an axis.

A camera can be arranged in the endoscope tip. This is preferably interchangeably arranged via a normalized interface. The camera is preferably connected to the end of the endoscope remote from the endoscope tip via a cable.

Furthermore, at least one light-emitting diode (LED) for illuminating the lumen to be mirrored can be arranged in the endoscope tip. The at least one light-emitting diode can also be connected to the end of the endoscope remote from the endoscope tip via a cable. Furthermore, it can be provided that a hygienic protective coating is arranged on the endoscope tip. The hygiene protection coating is preferably designed as a plastic sleeve made of flexible material. It can have an opening for the camera in the end-side end region. Otherwise, the plastic sheath can be arranged airtight on the endoscope tip detachably.

The camera and optionally the light-emitting diodes are preferably arranged on a disc-shaped carrier element. The disk-shaped carrier element can be arranged on a rod-shaped holder and held by this, wherein the rod-shaped holder is flexible in all directions. The rod-shaped holder preferably consists of a number of link elements.

The disk-shaped carrier element together with rod-shaped holder is preferably arranged on a connecting element. In this case, a preferred embodiment provides that the disk-shaped carrier element with rod-shaped holder and connecting element is arranged as a replaceable unit on the endoscope tip. It is advantageous if between the disc-shaped support member and the connecting element, an intermediate plate is arranged, which has guides for the tension elements. Furthermore, it is preferably provided that the tension elements are detachably connected to the disk-shaped carrier element, in particular by means of a clip connection. It is advantageous if there is protection for the end region of the endoscope for cleaning the endoscope (in a wax machine). A further development therefore provides that a protective cap is provided, with which the pulling elements emerging from the end region of the endoscope can be covered. This protective cap is preferably multi-part, in particular two-piece, trained. The protective cap is placed over the end area for the cleaning of the endoscope, so that no impurities can reach the inside of the endoscope body via the cable entry. The protective cap lies tightly over the end area.

The advantage resulting from the last-mentioned embodiment of the endoscopy device is that the "optical unit" can be detachably and interchangeably arranged on the endoscope tip, together with the above-mentioned actuation of the tension elements by the control elements (drive wheels for the loop-shaped tension elements) Modular and very inexpensive construction of the endoscope.

With the proposed solution functional functions can be realized.

Here, firstly, a rear-view mirror mechanism is mentioned, with which the endoscope tip is automatically rotated at a defined and differently selectable retraction speed. A fine air control via two pumps is possible to blow air into the intestine and to be able to aspirate again. This is important so that it can develop accordingly when pretending and a clear lumen can be achieved. So far, this function is operated via two valves directly on the endoscope handle. With the proposed solution in combination with a device box (functional stand), this function can be switched via two switches on the two console joy sticks (top buttons on the joysticks). An automatic feed with curve programming is possible, especially for the first curve in the rectum (sigma transition); Here, a defined bending of the endoscope tip can be programmed during the feed. Especially this first section of the colonoscopy is thus much easier explicable and reduces the need for assistance.

It is the realization of a freeze function possible, d. H. a set position is held electronically, a fine adjustment around the "frozen" point is possible.

Furthermore, electronic smoothing of the control movements can take place. This comes into play, in particular, when fast or gross motor movements are predetermined, which arrive at the endoscope tip as a gentle movement.

It is an automatic "high swings" when mirroring possible.When the intestine is deferred, it is beneficial if a certain amount of time is reduced back to the console this "anti-loop mode" can be realized, ie. H. with an automatic change of direction (forward / backward) in this mode the mirroring always automatically moves a little bit ahead (eg 4 cm) and backwards a bit (eg 2 cm).

The display of the rearview mirror time (in displayed minutes) is possible. An integrated jet irrigation system for rinsing even contaminated areas of the mucosa can be used to maintain a clear view during colonoscopy. The pump can be integrated in the device box, the operation is carried out on the console (in this case, use of water for use). For the operation of the endoscopy device, the following should be noted:

First, the endoscope (which acts as an optics carrier and is also partially designated here) is inserted with its end facing away from the endoscope end in a holder. The two cable loops are placed over the two rollers. These wheels are permanently mounted on the console and are controlled and driven by the joystick. As a matter of course, these wheels can also be manually turned or controlled if, in exceptional cases, the endoscope has to be picked up by the console in order to be able to rotate better.

Then, the endoscope end is moved away from the rollers so far that the two cable loops are stretched. Then a tightening takes place. The tensioning ensures that the cables are tensioned and have no play.

If in another variant four loose ends of the cable are present, there are not on the console but the rollers motion carriage with four linear drive rails, in which the cable ends are inserted.

The direction control of the endoscope tip (optical tip) is done by joystick control on the console.

The supply or function channels are connected either on a terminal block or with a sealing connection cap, so that the cables bundled pull to the device box, where air, water and vacuum are generated. Also available is the conventional working channel for the usual instruments. But it can also be a biopsy device constructed on the console at the appropriate position and swung over the working channel.

It is also possible to connect the hydraulic channel through which the degree of hardness of the support shaft can be changed (operation via the console) in order to avoid intestinal looping. It is also possible to connect an electrical cable for the LEDs to illuminate the intestinal lumen (instead of fiber optic cable). The power comes from the device box of the overall arrangement; the LEDs can be adjusted in brightness. Also possible are different light qualities or colorations with which structures can possibly be better recognized.

Also possible is a camera system that can have a magnification option (zoom effect). The air or water supply for the "curve cushion" in the flexion region of the support tip (endoscope tip) can be connected "Zentrierungsbürsten" are attached, as in a fireplace optics.

The camera cable is connected to the processor in the device box, ideally the power cable for the LEDs is a "small cable tree" summarized and the LEDs (1, 2, 3 or 4) sit on a wreath around the optics and form a unit that is interchangeable. It is useful if this cable harness can be pressed from the outside into a longitudinal recess. The advantage is that you can combine the camera head with LED ring and plug as a unit and can easily remove from the support element.

It is also advantageous if the entire condyle including camera unit can be easily changed by the four cables are posted at the endoscope end, as well as the flexible hose ends for the flushing or suction and for the instruments (working channel). Then only the "spinal column tube" must be unscrewed through a thread at the end of the carrier.Accessible is also an optic catheter, which can be pushed over the catheter end in the connection area by 2 cm forward If the optic is positioned in a retracted position on the condyle, the joint is straightened and the optics are pointing straight ahead.If you push the catheter tube forward, the optic angles itself to ensure that you can better behind the wrinkles in the case In the case of interventions, the angle of flexion of the support element (comparable to the conventional endoscope curvature area) is complemented by the angling directly at the optic and overall allows a greater bending of the optics with the two angled options , The endoscope (optics carrier) is clamped between the drive rollers of the feed device for the axial feed of the endoscope. The control forward / back is then carried out by foot pedal or joy stick. The optic carrier hangs down in a loop at the beginning of the colonoscopy. The loop shrinks the more, the farther the optics carrier drives into the patient.

If the endoscope is pushed open, it is possible to change the degree of hardness of the optics carrier shaft via the hydraulic pressure (one or more hollow chambers are filled with pressure) and thus support the straightening. The operation is done on the console. A very simple solution is to nachzuschieben a straightening rod in a hollow chamber of the endoscope.

For Lumenzentrieren at Vorspiegeln and Kurvenabpolsterung the endoscope curvature against the intestinal wall, it may be advantageous if the flexible cuff, which also acts as a hygiene protection, between the condyle and the end of the support element is inflatable. This can also be divided into four chambers, which can be inflated to different degrees and on the thus a kind of direction control is possible.

This direction control via the four chambers of the flex zone (curvature area of the endoscope) can also be automated by sensors.

A variant may also be that a direction control is achieved via four jet stream nozzles, which flow out laterally in the head area. In order to expand the diagnostic possibilities, a compartment for the use of a conventional ultrasound head should be provided in the end region of the support element.

With the modular components conception, it should be possible to exchange parts and at least partially use disposable products. In the process, a sanitary apron can fall down from the optics carrier head; it covers the open joint part (curvature area). For example, with an adhesive strip, the loose part of the sanitary apron can be hermetically sealed at the end of the carrier. It could be the camera or the light unit designed as a reusable component, which also fits easily into a conventional endoscope washing machine and can be prepared (as well as the use of a disinfectant solution is conceivable or the insertion into an autoclave).

If the viewing angle is insufficient, this can be increased by extending and thus simultaneously tilting the optical unit on the condyle. The endoscope (optics carrier) can be fixated flat on the console (for example via a quick-release system), whereby the cable pairs can be placed directly on the disc or annular control element ("deflection rollers") on the console ) and the optics can be easily separated from each other and assembled modularly or as a hybrid product (one part reusable, one part as a disposable article) In conventional endoscopes, the endoscope and optics are inevitably a unit that must be completely put into the washing machine , It is preferred that no optical fiber technology is used, but the lumen is illuminated by LEDs. Accordingly, advantageously no complex endoscope handle is necessary.

The repair-prone cables are easy to replace.

The flex zone can simultaneously act as a pressure cushioning and lumen centering. For greater angulation, two flex areas may be present.

It is advantageous given an optical zoom option (by a variable distance between the camera and a lens).

There are interchangeable and thus different camera heads can be used. This has the advantage that over time improved camera heads can be used without having to disassemble the entire endoscope. Instead of just one image sensor (optics), it is also possible to use two or more image sensors which produce an optimum image with high depth of field in the downstream image processing.

In addition, a satellite camera can be used on a separate guidewire; their control can be done by rotation as in the cardiac catheter.

It is also a 3 -D optical unit used. Since a standard optics can also be used, a cost-cutting potential can be developed at this point in a not inconsiderable manner.

Furthermore, an ultrasound unit can be coupled. For this purpose, the shaft can be used at the end of the support element for the endoscope.

The light emitting diodes (LED) used can have a variable color scheme. Thus, for example, a "blue light coloration" can be used to better recognize specific mucosal changes can.

The flex zone air cushion is preferably divided into 4 chambers or it consists of 4 chambers, similar to the inflatable cuff at the tracheal tube, which correspond to the "12 o'clock position", the "3 o'clock position", the "6 o'clock position". Position "or the" 9 o'clock position "are aligned and can be inflated to different degrees. Each equipped with a pressure sensor, an automatic pre-reflection can be realized. The pressure sensors can also be constructed independently of the air cushions in a kind of wreath structure ("Advent wreath"), which can be placed on the endoscope tip and forwards the signals for electromechanical calculation and control movement via the pairs of cables (curve cushion, automatic mirror, "Lane-Assist"). ).

Another advantage of the described solution according to the invention is that no voluminous device tower is required near the endoscope. In previously known solutions (see Fig. 3 below), because of the limited length of the supply hose, a device tower often has to stand in the middle of the room or close to the patient's bed. With the proposed concept, however, there is the possibility of the camera electrical cable or the To let the fiber optic cable or cable for the supply of LEDs longer and so to place the processor at the edge of the room. This may also open up the possibility that two endoscopy stations use a processor (the processor usually has several image processing inputs).

Finally, it is advantageous that, in comparison with the previously known solution, the supply hose is no longer part of the hermetically sealed system, since this functionality is designed to be disconnectable. Accordingly, this part does not have to be in the washing machine. Thus, much smaller washing machines can be used for cleaning the endoscope. In particular, the detachable cables for the illumination of the lumen to be examined and the camera need not be sterile. In the drawing exemplary embodiments of the invention are shown. Show it:

1 shows schematically an endoscopy device comprising an endoscope and an endoscope tip actuating device,

2 shows parts of the endoscope tip with actuation cables and a camera, FIG. 3 shows a prior art endoscope, and FIG. 4 shows an endoscopy device according to the invention.

In Fig. 1, an endoscopy device 1 is shown, which essentially comprises an endoscope 2 (this can also be addressed as an optic carrier) and an actuator 23 for the movement of the endoscope tip 3. The movement of the endoscope tip 3 takes place - as is known per se - by means of four tension elements 4, 5, 6 and 7, which move the endoscope tip 3 in the direction of the arrow on the right in FIG. 1 by corresponding pulling or slackening (ie into a "3 -Clock position "," 6 o'clock position "," 9 o'clock position "and" 12 o'clock position ").

Instead of leaving the four tension elements 4, 5, 6, 7 in the end region 8 of the endoscope 2 in adjustment with handle, as is the case in known endoscopes, it is provided here that the four tension elements 4, 5, 6, 7 in the end region 8 emerge from the endoscope 2, wherein each tension element 4, 5, 6, 7 is in communication with the actuating device 23, with which the respective tension element 4, 5, 6, 7 in the longitudinal direction L of the endoscope 2 is movable. 1, it is provided that in each case two tension elements 4 and 5 or 6 and 7 which correspond to a direction of movement (see arrows in the right-hand end region of FIG. 1) form a loop 9 or 10. Each loop 9, 10 is guided around a disc or annular control element 11 and 12, wherein this is in communication with a rotary drive 13, 14 in the form of a servomotor. The controls 1 1, 12 rotate concentrically about an axis a. They are connected via drive means 15 and 16 in the form of toothed belts with the rotary actuators 13, 14.

It is also possible to make the controls 1 1, 12 releasably on their shafts and to keep the loops 9 and 10 looped around them. The controls 1 1, 12 can be kept as a unit with the endoscope 2. So that a slip-free drive of the loops 9, 10 can take place, means 17 for adjusting the distance between the end region 8 of the endoscope 2 and the axis a are present. These means 17 also include - which is indicated only schematically - spring means which hold a resilient bias in the loops 9, 10 to ensure their slip-free drive from the controls 1 1, 12.

With regard to the configuration of the endoscope tip 3, reference is made to FIG. The endoscope tip 3 has a rod-shaped holder 21, which consists of a number of link elements 22. With the rod-shaped holder 21, a disc-shaped support member 20 is pivotally supported in all directions. On the disc-shaped support member 20, a camera 18 is placed centrally. In the present case four light-emitting diodes 19 are arranged around the camera 18 with which the lumen to be mirrored can be illuminated.

The end portion 8 of the endoscope is - which is shown schematically - held by a swing-away bracket against slipping. It may optionally also be an automatic tension of the loops 9, 10 done with a spring tension system, so that the tension elements (cables) are always tense and have no play.

It can be inserted in one or more channels in the endoscope curve stabilizers in the form of harder rods, which can be pushed from the end of 8 up to the relevant flex zone. Thus, the endoscope 2 can be made harder so that it does not easily postpone itself in the intestinal loops. Alternatively, one or two chambers can be filled with compressed air or water in order to increase the degree of hardness of the endoscope shaft with pressure-filled chambers. For this purpose, a customized supply cap can be used with all the connections that go to the control box or console, from where air, water and electricity comes from.

The connection of the required supply lines, which run partly in internal channels, partly also on outer longitudinal recesses, via a compact terminal block.

The fine air regulation for the unfolding of the intestinal lumen or for the aspiration of the "examination air" can take place via an internal channel which exits at the final level (in the area of the end area 8.) If necessary, an additional channel for the suction can make sense (in the case of "Jet stream" must be sucked off at the same time also at the same time). The endoscope 2 is provided with the required channels extending in the longitudinal direction L: There may be at least one working channel, a channel for the camera cable and a power cable for the LEDs, a lens washer, a purge suction channel, four jet airflow channels, the above the flex zone open at the sides of the "12 o'clock position", "3 o'clock position", "6 o'clock position" and "9 o'clock position" and blow against the intestinal wall. Due to the "recoil effect", the endoscope tip moves away from the intestinal wall and can thus be controlled with lumen centering. Alternatively, the four nozzles blow into four small balloons (at the four named positions), which, depending on the filling state, move away from the intestinal wall and thus the endoscope tip. The small balloons then each have a pressure sensor, via which the optimum filling states for the control can be automatically realized.

Shafts for further functional modules (eg ultrasound unit) can also be provided. For hygiene protection, an external attachment zone can be provided. The hygiene protection can be clipped onto the optical head from above as a ring and, like a cape, can be pulled down over the flex zone, covering the cables and cables. This cape is inflatable as a balloon at the same time, it acts as a pressure pad when it has to be driven around the bend, it generally acts as a centering. Thus, to achieve a sufficient overview also less air must be injected, which leads to less discomfort in the patient. The four cables are beyond the end of the bracket 21 and are clicked into the support member 20.

In this case, two working channels can be provided which protrude beyond the end of the carrier element 21 (optical carrier).

The optical unit shown in Fig. 2 can be used contiguously from above into the end portion of the endoscope 2. The unit consists of the support member 20 (top plate) with removable camera and LEDs, the recording for the cables and the working channel, a Ring band, an insert plate in the carrier, cables for camera and LEDs and lens rinsing.

Specifically, the following structure is provided (see Fig. 2): The disc-shaped support member 20 carries the camera 18 and the LEDs 19. The support member is supported by the rod-shaped bracket 21, wherein the holder 21 is disposed on a connecting element 24 (connecting disc). The tension elements 4, 5, 6, 7 are guided by an intermediate plate 26, wherein 27 are incorporated in the form of holes in these guides. The tension elements 4, 5, 6, 7 are fastened at their upper end by a clip connection 28 releasably in lateral grooves of the support member 20. Accordingly, a unit 25 is created which can be replaced.

It can also be provided an additional camera. This can be carried out at the front as a "guide wire" (second camera system on a catheter wire with pre-curved tip, see cardiac catheter, directional control thereby turning the "torsion bar" which protrudes from the bottom of the end cap). The advantage is that you can also look backwards behind the wrinkles during the diagnostic mirroring. It is also advantageous that can be pre-scouted at confusing places.

It does electrical lighting instead of conventional using fiber optic cable and an external light source (which requires a large equipment box). The light-emitting diodes are advantageously dimmable for lighting.

The hygiene protection with air cushion allows a curve pad and a lumene centering. Ideally, there are four sensor pressure controlled chambers available. The air cushion prevents too much air during the examination (so no C0 2 more, since it is only a small pad in front of it). The 4-chamber air cushion is also used for centering when pretending in "surf mode", during flexing or for precision control with additional cable pulls. It can also be automated as a navigation system with corresponding pressure sensors in the sense of automatic centering. Alternatively, only four laterally outflowing air nozzles are possible, which blow directly against the intestinal wall and keep the tube lumenzentriert by the "recoil".

The flexible optical carrier 2 as endoscope replacement is directly and flat without attachments to the existing endoscope console fixable, the four cables 4, 5, 6, 7 are alternatively connected to the solution shown in a corresponding "Zugschlitten" (with four linear actuators) connected to the console ,

The two controls 11 and 12 can be the same size (not as usual on the endoscope handle a small and a large wheel, which is necessary there in the different sizes to allow a "grip difference").

In the event that the endoscope has to be removed from the console holder, auxiliary control wheels can be used to allow manual control ("emergency handle").

The flexible optics carrier (endoscope 2) is long enough, so that no nachfuhrbarer recording slide is necessary (the "endoscope loop" must be able to sag). On the flexible optical carrier (endoscope 2), a connection strip for the supply lines can be present directly, in another variant also as a tightly mounted supply cap with a supply hose to the control box, from the air, water and vacuum comes.

It can be further provided a guide tube for a displayable 45-degree optics (as in the laparoscopy), in the inserted state results in a straight-ahead optics when z. B. 2 cm is advanced, the optics angle (can then be rotated all around with the guide tube).

Stabilizers can be used for straightening (which also changes the hose hardness). The optics insert with illumination LEDs can be designed as a replacement component on a thin spiral tube as angle optics (rotatable, exchangeable in 3-D module). The flexible optics carrier can be equipped with an Endo-Sono module. It can be combined as a hybrid system with Einmai components.

The second working channel can exit at an angle so that the instrument hits the tissue more tangentially.

It can be provided a stiffening option, especially in the first 50 cm (main area of looping).

The camera can have a zoom area with lens and an approachable optical head. An embodiment as a flexible carrier element as a round profile with a plurality of hollow chambers as inner chambers is possible, can be pulled through the lines or have the longitudinal recesses into which hose elements can be inserted from the outside.

Another solution is based on a flexible support element as extruded WPC profile, this can be adjusted accordingly for all required lines, partly inside, partly from the outside into the longitudinal recess inserted (120 cm longitudinal profile pieces with initial element with the four through cable trailing edges and terminal block for the supply functions and a termination element to which the flexible header can be attached).

It is also a flexible support member as a sheathed spiral hose (such as a "shower hose") possible in which run the whole lines or channels and is adapted accordingly.

It can be provided a harder rod, which can be inserted for stabilization in the endoscope. Furthermore, a hydraulic longitudinal chamber is possible by means of which a pressure can be built up for stiffening (with air or water). Furthermore, vacuumable beads are possible (such as the stabilizing effect in the vacuum mattress for accident victims). Furthermore, elements can be provided which are strung on a string (if the string is loose, the elements have play and can undergo bending, when the string is stretched, the elements are pressed together and the whole becomes stiffened). The flex zone can have four lateral jetstream outlets for "windsurfing control" (four cables as control cables, central support for the condyle), flexible supply hoses for the flushing-suction function can be used, and a flexible duct as working channel.

The optical unit can be exchangeable and vorschiebbar, with a Abwinkein is possible (total rotatable at the "hose end", which protrudes from the starting area).

Furthermore, a shaft for an ultrasonic unit can be used.

Furthermore, replaceable rod ends with optics carrier are possible (ie interchangeable lenses). The final plane of the carrier may have two openings of the inner channels for fine air on / off, further, a central receiving point for the "spine-like" joint tube may be provided

The cables and two hoses for the purge / suction function and the working channel as well as the optics (with LEDs as lighting ring) can be clipped onto the head cover.

For the required cables and similar elements - especially with regard to the cable of the camera and the LEDs - slot-shaped recesses can be provided in the respective components in order to be able to lay them easily, especially in a detachable configuration of the arrangement without having to solve plug-in connections , A particularly advantageous embodiment of the present invention is apparent from Figures 3 and 4, wherein FIG. 3 shows a prior art endoscope 2 and in comparison with FIG. 4 shows an endoscope 2 according to the present invention.

For the solution according to the prior art - s. Fig. 3 - it should first be noted that the endoscope 2 hereafter in a known manner an insertion tube 29, at the end of the endoscope tip 3 is located. At the end of the endoscope 2 which is at a distance from the endoscope tip 3, a control body 30 is arranged, which comprises the control wheels for moving the endoscope tip 3 (see the above explanations for this). Shown is also a working channel input 33.

The previously known endoscope 2 comprises as an integral unit further a supply cable 31, at the end of a supply plug 32 is arranged, with which the endoscope 2 to a processor 34 (shown only in Fig. 4) can be coupled. The supply connector 32 for the connection of the endoscope 2 to the processor 34 is connected via a ballast (located in the supply connector 32). This element, which is known per se, has the task mentioned below of undertaking signal conditioning.

A disadvantage of this solution is that the entire unit shown in Fig. 4 of the endoscope 2 must be cleaned after use. Furthermore, the entire unit shown must be completely replaced in the event that parts of the device are defective. Accordingly, therefore, the entire arrangement shown in Fig. 3 must be disinfected as a hermetically sealed unit in the washing machine. The maintenance and repair (if possible) is correspondingly complex and expensive. In this regard, the inventive solution shown in Fig. 4 provides a remedy. The construction here is generally general, as shown for the above embodiment of FIG. 1. Accordingly, in the end region 8 of the endoscope 2, tension elements 4, 5, 6 and 7, which form two loops 9 and 10, which are actuated via control elements 11, 12 in the above-described manner, terminate. In addition, the solution according to FIG. 4 has the design according to which two cables 25 and 26 are led away from the end region 8 of the endoscope 2, namely a supply or optical cable 35 (in the case of the direct supply of light from the processor 34, it is that is, an optical cable, in the case of the supply of LEDs in the endoscope tip to electrical supply cable), which may be designed in particular as a fiber optic cable, and an electric cable 36, which is in particular a camera cable. At the end of the two cables 35, 36 is ever a plug 37 or 38, with which the two cables 35, 36 are inserted into an adapter 39 releasably inserted. In the adapter 39 is a ballast, with which a signal conditioning can be done. The purpose of this ballast electronics is that the interface to the processor 34 in comparison to the solution of FIG. 3 is unchanged. Accordingly, in an existing processor 34 for the evaluation of the endoscopic examination, the adapter 39 can be inserted, which corresponds to the supply plug 32 (see Fig. 3) of the previously known solution.

In each case, individual components of the endoscope 2 can be replaced by the respective detachable and modular design; still intact Components can be used unchanged, which allows a significant cost savings.

According to the invention, therefore, an endoscope is modified so that it can be coupled directly to the controls 1 1, 12 without the usual control wheels, in which case further comprises a detachable plug connection 37, 38 to couple the thus modified endoscope 2 to an existing processor 34 can. So there is a semi-open endoscope concept with a direct coupling of the supply lines directly to a control console, d. H. it is no longer the typical handles with steering wheels longer provided.

This results in significant advantages, also from the point of view of hygiene, since a much smaller device must be disinfected. The endoscope 2 is unchanged from the endoscope tip 3 to the end region 8 (see Fig. 4) compared to commercially available endoscopes.

Preferably, therefore, a camera is arranged in the endoscope tip 3, light being supplied by the optical fiber line (coupled via the plug 37) for the illumination of the site to be endoscopic. It is also possible to provide a lens rinsing (not shown), an opening for the working channel 33 can also be seen. The function of the required valves in the endoscope can be transferred to a control console and thus omitted on the endoscope itself. Provision can be made for a removable hygiene cover (which can be disinfected separately) on the console covering the mechanics (controls 11, 12) and clean joints and sealingly seated on the endoscope tube just above the working channel area 33. In the direction of the endoscope tip 3 is the "dirt area", which can be colored if necessary.

A new and simple cistern with disinfectant solution is sufficient for disinfecting the open half endoscope (ie for the area between the end region 8 and the endoscope tip 3 in order to clean the part of the endoscope 2 to be disinfected 4 shows the (detachable) coupling of the supply or optical cable 35 and the camera's electrical cable 36. Analogously, the required air and water media lines can be connected to the end region 8 of the endoscope Accordingly, as the end region 8 of the endoscope is modified so that the previous known supply lines (leads, leads) can be connected directly to a device box or a console detachable, and are the Steering wheels (on the control body by 30) no longer available; the movement of the endoscope tip 3 takes place in the manner shown in Fig. 2.

The same applies to stylus elements (in particular for the image adjustment), which are located in the prior art solution according to FIG. 3 in or on the control body 30. Such functional elements can also be detachably coupled to the end region 8 of the endoscope. At the end portion 8 of the endoscope 2 also connections for the fine air control can be detachably coupled. The existing lines for this, which are present in a previously known endoscope (see Fig. 3) are used for this purpose; detachable couplings connect the media feed and discharge lines from a control console. Only the cables 35 and 36 "open" to previously known image processing equipment (processor) and external light source devices, but it is also conceivable that these two cables or light guides have an additional detachable Konnektionsmöglichkeit in the end (console area) of the endoscope.

To disinfect the endoscope 2, the cables 35 and 36 are released from the end portion 8 of the endoscope 2 and arranged the above-mentioned sealing cap on the cable loops. The cables 35, 36 are then hung up rolled on a disinfection costs and are only wiped off by surface disinfection. The thus prepared endoscope can then in the washing machine or in a special disinfection box or in an ultrasonic bath, as it is known for the preparation of endoscopic instruments. In addition, it is expedient to connect the supply and discharge hoses to perfusion hoses for complete cleaning, which continuously flush the disinfectant solution from the disinfection box through the polluted lines during the treatment via pumps.
