- Endoscope shaft for the bendable connection of a distal tip of the
- Endoscope shaft with a proximal endoscope section and a
- Endoscope head attachment for an endoscope with such a folding mechanism.

- such endoscopes may be provided with additional capabilities, such as by placing a cap or sleeve on the distal end of the endoscope / endoscope head radially outward of the endoscope head, which may engage with certain
- Pancreatic duct forms in the duodenum, laterally into the duodenum
- protruding are conventional prograde (looking in endoscope longitudinal direction)
- Endoscopes for such procedures unsuitable because there is insufficient pivoting space in the narrow duodenum (diameter 3 to 4 cm) is available to align their prograde optics and the working channel in a sideways-looking position, since a typical bending diameter of such devices is about 12 cm.
- duodenoscopes which have a lateral (looking sideways) or retrograde (retrospective) optics (also called “lateral optics”) and a sideways working channel , At the output of the working channel such
- Duodenoscopes also usually a so-called albarran lever is provided, which allows pivoting a targeted guiding / deflecting a run in the working channel tool. Due to the sideways arrangement of
- Functional units on the endoscope head allow imaging and treatment in the area of the duodenum with optimal use of the available space.
- Ring elements which form the support structure of the shaft and Bowden cables, often called Biege horrinum, operated and tilted against each other.
- Biege horrinum In order to facilitate insertion into the cavity and to prevent the ingress of substances, the ring elements of a flexible sheath of a
- each articulated interconnected ring elements formed hinge portion only a relatively large bending radius, since the individual ring elements each have only a small tilt angle to the next ring element.
- the articulated connection of two elements only allows tilting about one axis, it is for a spatial bending possibility required to arrange elements with tilting axes rotated alternately against each other, so that only every second element can be deflected in a desired direction; This further increases the possible minimum bending radius.
- the near area next to the shaft end is therefore not visible with a arranged in the endoscope optics.
- duodenoscopes suitable that require a sideways-oriented working channel.
- Cylinder casing section with a minimum axial length and arranged in the opposite cross-sectional half of the respective segment, in particular in
- Axial length cylindrical cylinder sections axially support or rest on each other, whereby at the supporting or support point a hinge or
- each segment forms a portion of its lateral surface, i. at a radial
- the successive in the axial direction of the endoscope segments are arranged relative to each other that said wedge tips are each in alignment when the Abklappmechanismus is in a straight-ahead position.
- a region of maximum axial extent of the individual segments is arranged in a region of the respective segment facing away from the wedge tip. These areas of maximum axial extent are in the straight-ahead position in alignment and form a joint or tilt contact between each adjacent segments.
- a folding mechanism of an endoscope shaft connects a distal tip of the endoscope shaft with a proximal one
- the Abklappmechanismus has a number of axially successive and means at least one actuating element against mutually angle-adjustable segments, the (m inside their cross-section) at least one in the axial direction of the
- Endoscope shaft extending channel for performing minimally invasive
- Surgical instruments, rinsing media, supply lines and the like define the individual segments of Abklappmechanismus are inventively formed in their basic form as wedge-shaped (circular) cylindrical cutouts, each with their remote from the wedge tip, in the axial direction wider ends of support or hinge portions adjoining each other angle adjustable. Due to the wedge shape of the segments and the aligned in the axial direction or adjacent arrangement of each adjacent widest portions of the wedge shape of the relative rotation of the respective adjacent segments as far as possible be moved to the edge region, whereby a comparatively large clear space between the tips of the wedge shapes generated and a relatively large possible tilt angle between the individual
- Endoscopes that are equipped only with a conventional Deflecting, also the lateral near range can be edited and viewed through an endoscope with such a folding mechanism.
- the actuating element for angle adjustment between the segments may be formed as at least one tension element, which by means of
- At least one channel for the at least one tension element can be formed axially through the respective segments, so that it runs in an inner lumen of the segments.
- Embodiments for the tension element are, for example, cables.
- the tension element may be formed as a Bowden cable, which is at least indirectly anchored or supported on the most distal and at the most proximal segment arranged segment and this for folding / Abkrümmen of
- the return to the straight position can be done either via a shear stiffness (as in a shear-resistant Bowden cable) or on the inherent elasticity of the compound of the wedge segments or with incorporated spring elements.
- the extending in the axial direction tension element in the opposite of the wedge tips end portions of the segments extending but be offset radially inwardly relative to the support or support points of the segments, so that when applying a tensile force with respect to the support or support points of the segments forming a wedge tips contracting lever.
- Endoscope to be arranged out so that the wedge-shaped segments when applying a tensile force on at least the distal segment fold toward each other and abut each other flat in their final position.
- the number of wedge-shaped segments and the angles of the respective wedge shapes of the segments can be adapted to one another such that in a maximally folded-down position of the folding mechanism, a folding angle of at least 80 °, preferably at least 90 °, more preferably at least 1 10 °.
- the summed angles of the wedge tips can be more than 80 °, so that in a maximally angled position of the folding mechanism, in which the respective adjacent segments lie flat against each other, the distal End surface of the distal end segment by 80 ° or more relative to the
- Endoskoplashessachse employees is.
- 90 ° are advantageous because the papilla can be reached only retrospectively depending on the anatomical conditions.
- the segments may be designed in their wedge shape such that in the maximum folded position of the folding mechanism, the inner radius of curvature of the
- the curvature inner radius of the folding mechanism can be smaller than half the diameter of the fold-down mechanism in the maximum folded-down position (for example, a position bent at 90 °)
- Embodiment of the invention in a folded down by 90 ° position of the Abklappmechanismus, the distal end of the endoscope head by less than 2 cm, preferably less than 1 cm, more preferably less than 0.5 cm, over the lateral surface of the Abklappmechanismus in the projecting prograde alignment.
- the Abklappmechanismus be designed so that it (or its lateral surface) in a folded-down position by 90 °
- Curvature inner radius of less than 1 cm, preferably less than 0.5 cm forms.
- the folding mechanism can have between 3 and 5, preferably 4, wedge-shaped segments. It has been found that, with a number of segments that moves in this area, folding into a lateral viewing direction with the smallest possible bending radius can be achieved particularly well.
- the working channel can be arranged in the region of the outer radius of the bend of the folding mechanism. This has the effect that the bending radius of the working channel does not become too small / narrow, so that it is still possible to pass on minimally invasive surgical instruments.
- two cables can be provided in the remote from the wedge tips end portions of the segments, between which a working channel for performing minimally invasive surgical instruments (also in the area away from the wedge tips area) is arranged.
- a working channel for performing minimally invasive surgical instruments also in the area away from the wedge tips area
- the cylinder jacket portion with maximum axial length is not diametrically opposed to the cylinder jacket portion minimum axial length but arranged to be offset inwardly toward the soul of the endoscope.
- the working channel may have an oval cross section, the longest diameter of which extends in the folding direction of the folding mechanism. In this way, a narrowing of the working channel during the bending can be counteracted and the fürchiebles of minimally invasive surgical instruments is maintained even in the 90 ° or more angled state.
- the oval cross section of the working channel may have an oval cross section, the longest diameter of which extends in the folding direction of the folding mechanism.
- Working channel also allows a sensitive alignment of the tool, since you can move the proximally to the rigid tool tip subsequent flexible shaft in the oval working channel laterally and thus fine-tune the tool (analogous to fine adjustment, in conventional duodenoscopes with the
- the support or support points between the segments may be formed as film hinges.
- the basic structure of the folding mechanism can be produced in one piece, for example, as an injection molded part or by additive Manufacturing processes.
- other common common of the folding mechanism can be produced in one piece, for example, as an injection molded part or by additive Manufacturing processes.
- Embodiment with separate segments can, for example, be held by a suitable sheathing against each other.
- the wedge-shaped segments may be recessed in alignment in the region of the wedge tip, so that there is a rib-like structure towards the inner radius of curvature of the Abklappmechanismus out.
- an inner lumen of the endoscope is defined in which spray or suction channels,
- Cooling channels, electrical lines for supplying the lighting and imaging and the like can be performed.
- Another, optionally independently claimable aspect of the invention relates to an actively deflectable portion of an endoscope shaft - also called Deflecting - for the bendable connection of a distal tip of the endoscope shaft with a proximal Endoskopschaftabites.
- Said Deflecting has a plurality of axially successive and by means of at least one actuating element against each other angularly adjustable segments, which in the axial direction at least one channel for performing minimally invasive surgical instruments, rinsing media,
- the actively deflectable section has a proximal section which can be bent in at least two different directions and has at its distal end region a fold-down mechanism, in particular integral with the proximal section, according to one of the aforementioned aspects.
- an endoscopic deflector known from the prior art can be adapted such that its distal members form a fold-down mechanism as described above.
- An endoscope with such Deflecting thus has the usual Abkrümmfunktionen
- proximal Abkrümmabites and the Abklappmechanismus each have separate actuators / control mechanisms (eg Bowden cables).
- the control mechanism of the folding mechanism can advantageously be performed by suitable channels in the proximal actively deflectable shaft portion.
- Another and optionally independently claimable aspect of the invention relates to an endoscope head of the endoscope-adaptive design in the manner of a separate, additional endoscope head essay. This one has a proximal one
- Folding mechanism according to one of the aspects described above, which in turn at its proximal end has a fastening means for releasable attachment to the endoscope head of a (separate) endoscope.
- Abklappmechanismus is the actuator (eg. A Bowden cable) on the adapted endoscope along or guided within the working channel in the direction of proximal to the user.

- Fig. 6 is a side view of the folding mechanism according to the invention.
- Fig. 1 serves to illustrate a preferred application of a
- Endoscopes according to the invention or a Abklappmechanismus invention.
- Fig. 1 shows the papilla vateri (P) located in the dorsal descending part of the duodenum (D) and relatively difficult to access due to the tortuous geometry of this system.
- the available space in the region of the duodenum (D) is very limited, so that interventions on the papilla vateri (P) with conventional, prograde endoscopes are not possible because with a corresponding bending of the endoscope tip in the direction of the intervention section no longer sufficient distance to the lumen of the duodenum (D) for proper imaging.
- duodenoscopes mentioned above are known, which have a fixed sideways or retrospective optics and a correspondingly aligned working channel to make optimal use of the available space.
- duodenoscopes have the disadvantage that they are fixed in their lateral / retrograde orientation of the optics and the working channel. On the one hand this complicates the general navigation within the patient and on the other hand makes such endoscopes inflexible in their possible uses. In other words, they are expensive special equipment for a narrowly limited
- a basic idea of the present invention is therefore a
- Endoscope head which carries the optics and the working channel output of the endoscope, can be pivoted together by at least 90 °, without the need for a large bending radius is required.
- FIG. 2 shows a first exemplary embodiment of a folding mechanism 10 according to the invention in a first prograde orientation.
- an endoscope head 4 shown in FIG. 1 is arranged in the fully assembled endoscope 2, which has various functional units such as an optic 6; Bulb 8 and a working channel 14 has.
- the clarity 1 and in the following only the most necessary functional units mentioned above are shown, of course, an inventive
- Endoscope head in addition to various other known in the art
- Functional units such as cleaning nozzles for a lens of the optics 6, suction channels, etc. have.
- the folding mechanism shown has a base body 12 with a number of segments 16 (16 ', 16 ", 16'” and 16 "") arranged successively in the axial direction of the endoscope 2.
- the individual segments 16 basically have a wedge-like shape, i. their distal and proximal end faces converge towards each other at an acute angle and meet in a wedge tip 18.
- the axial extent of the individual segments 16 in the section (20) remote from the wedge tip 18 is greatest.
- the individual segments 16 are in the illustrated embodiment, moreover, a circular cylindrical cross-sectional shape in order to achieve a circular cross-section of the entire endoscope 2.
- the wedge tips 18 and facing away from these portions 20 are aligned in the erected / extended position of the folding mechanism 10. This has the consequence that the folding mechanism 10 is unidirectionally angled.
- Sections 20 each to each other and form support or support points 22 around which the individual segments 16 are tilted relative to each other. Due to the wedge shape of the segments 16 are shown in Fig. 2, erected position to the wedge tips 18 down sawtooth free spaces in the main body 12 of the
- Folding mechanism 10 is formed.
- the segments 16 which can be tilted about the support or support points 22 can thus be folded toward one another while reducing these free spaces, as shown in FIGS. 3 and 4, until the respectively proximal and distal end faces of adjacent segments 16 in the position shown in FIG. maximum curved position abut each other. Due to the fact that the wedge tips have a relatively small axial extent of less than 1 mm, the position shown in FIG. 5, which has been folded down by 90.degree
- the low bending inner radius has the advantage that optics 6 and 8 light bulbs in said folded position does not protrude far beyond the outer circumference of the endoscope.
- the distal and proximal end faces of the individual segments 16 are each set against each other by 23 °, so that there is a maximum Abklappwinkel of a little more than 90 ° in four segments.
- Bowden cable channels 24 are provided in the segments 16 in the region remote from the wedge tips 18, in which Bowden cables not shown in FIGS. 2 to 5 but shown in FIG. 6 are guided. These are offset by a small distance (here: 1 to 3 mm) with respect to the support or support points 22 in the direction of the wedge tips 18, so that at a Glaskraftbeaufschlagung of the distalmost segment 16 ', on the so defined Flebelarm h (See Fig. 6) a torque is generated in the support or support points 22, which causes a folding / bending of the folding mechanism 10.
- the displacement of the Bowden cable channels 24 on the side facing away from the wedge tips 18 side 10 of the segments has the advantage that the region of the wedge tips 18 thinner
- the hinge sections formed as film hinges 22 provide a relative pivoting of the segments 16 about a defined pivot axis. Since the lever arm h shown in FIG. 6 is comparatively short due to the structural design described above, under certain circumstances relatively high tensile forces are required for folding down the folding mechanism 10. This can be compensated for by providing a corresponding force reinforcement on the handle of the Bowden cables, for example via a toggle lever or the like. As indicated in FIG. 6, the Bowden cable may be anchored to the distal end surface of the distalmost segment 16 'and supported by its sleeve on the proximal segment 16 "" to effectively apply the tensile force F to the distal end
- the inner region of the individual segments 16 is provided with a plurality of cavities.
- Segments in each case have aligned cavities, so that 10 different channels result in the axial direction of the folding mechanism.
- the working channel 14 extends between the two Bowden cable channels 24 in the remote from the wedge tip 18 areas 20 of the segments 16. This has the background that when folding the Abklappmechanismus 10, the bending radius of the working channel 14 is kept as large as possible. While the smallest possible bending radius of the entire Abklappmechanismus is desired to reduce the radial board of the endoscope tip in the folded state, the largest possible bending radius per se for the working channel 14 per se, so
- Minimally invasive surgical tools W can still be "pushed around the curve" in the folded-down state of the working channel 14.
- the individual segments 16 further form an inner lumen 26 through which various further functional and supply channels of the endoscope 2 can be guided. Examples of these are irrigation, suction and insufflation channels or electrical / electronic lines for supplying the imaging (of an image sensor, not shown) or of the illumination means 8, which have to be guided by the distal endoscope tip to a proximal base station.
- irrigation, suction and insufflation channels or electrical / electronic lines for supplying the imaging (of an image sensor, not shown) or of the illumination means 8, which have to be guided by the distal endoscope tip to a proximal base station.
