Definitions
- the invention relates to a laser catheter for glaucoma treatment with a light-guiding fiber arrangement, at the proximal end of which light can be coupled into the fiber and at the distal end of which a light exit surface is provided, from which the light emerges from the fiber.
- the sponge-like trabecular mechanism through which the aqueous humor flows from the anterior and posterior eye chambers, is preferably removed locally with UV light, which is generated by means of an excimer laser and guided into the interior of the eye via light guides, so that the aqueous humor in the Schlemm'schen is easier Can pass through which it is ultimately discharged.
- UV light from an excimer laser with the aid of optical fibers in order to perforate the trabecular mill on site by local tissue ablation.
- Previously known laser catheters have at their distal light exit end a light exit surface cut perpendicular to the fiber axis, through which the light leaves the laser catheter in the longitudinal direction of the fiber on the distal side.
- the conventional laser catheters prove to be disadvantageous, especially since their distal end cannot be brought into close proximity or in direct contact with the tissue of the trabecular mechanism to be perforated, since this is located in the tapering chamber angle.
- 1 shows an image of a section of an eye chamber angle, which is included as an acute angle from the cornea H at the transition to the dermis L and the iris R at the transition to the ciliary body Z.
- the trabecular mechanism T located in the angular range must be perforated with suitably designed laser catheters.
- the invention has for its object to form a laser catheter for glaucoma treatment with a light-guiding fiber arrangement, at the proximal end of which light can be coupled into the fiber and at its distal end a light exit surface is provided from which the light emerges from the fiber in such a way that the Carrying out a glaucoma treatment can be carried out reliably and effectively.
- the solution to the problem on which the invention is based is specified in claim 1.
- a laser catheter for glaucoma treatment with a light-guiding fiber arrangement at the proximal end of which light can be coupled into the fiber and at the distal end of which a light exit surface is provided, from which the light emerges from the fiber, is designed in such a way that the light exit surface faces the longitudinal axis of the fiber arrangement encloses an angle of approximately between 30 ° and 70 ⁇ , preferably 37 s .
- the laser catheter designed according to the invention has a beveled light exit surface, the angle of inclination of which is adapted to the chamber angle within the eye relative to the longitudinal axis of the fiber. In this way, it is possible to guide the laser catheter in close proximity or in direct contact with the trabecular mechanism in order to carry out targeted light application into the interior of the trabecular mesh tissue with suitable positioning.
- the bevel according to the invention makes it possible for a surgeon to pass the distal tip of the laser catheter through the trabecular mechanism during the light application, all the way to the Schlemm's canal, the outer wall of which can also be perforated under certain circumstances, as a result of which the aqueous humor located in the interior of the chamber can flow through the perforation channels into the Schlemm'sche channel easier.
- the design according to the invention of the distal tip of the fiber arrangement makes it possible, in particular, for the tissue to be ablated to lie over the entire surface in the chamber angle region on the light exit surface, as a result of which there is direct optical coupling between the glass fiber and the tissue. If the light exit surface did not lie directly on the tissue area to be ablated, the aqueous humor present in the ventricular angle would cause considerable absorption, which would significantly impair the success of the treatment.
- the slanted light exit surface also offers the operator greater ease of use, especially since the fiber arrangement can be handled directly and in a straight line through the front chamber.
- the surgeon maintains an almost unrestricted overview of the tissue area to be treated within the chamber angle, even during the treatment of the chamber angle, since the fiber arrangement only covers that tissue area for optical observation that is separated from the light exit surface for reasons of local light deposition and a related tissue ablation is contacted.
- the fiber arrangement is composed as a monofiber or from a bundle of individual fibers and, at least at its distal region, has support material which radially surrounds the fiber arrangement.
- the support material which is preferably made of biocompatible plastic or metal, serves on the one hand to increase the longitudinal stability of the fiber arrangement in order in this way to permit straight-line catheter guidance, but is also provided at the distal end of the fiber arrangement for reasons of increased break resistance.
- the support material which, for example, is made of stainless steel and surrounds the fiber arrangement, in particular gives the surgeon safe positioning of the fiber arrangement due to the increased longitudinal rigidity.
- the support material surrounds the fiber assembly and ends flush on the distal side at the edge region of the light exit surface in such a way that the direct contactability described above between light exit surface and tissue region remains unaffected within the chamber angle.
- Typical size arrangements for fiber diameters are between 50 and 400 ⁇ m for fiber arrangements that consist of only one mono fiber, fiber arrangements that consist of a bundle of a large number of individual fibers are each composed of individual fibers with diameters between 1 and 100 ⁇ m.
- the support material increases the entire fiber diameter only slightly.
- Typical wall thicknesses of the support material are between 100 and 500 ⁇ m.
- the fiber arrangement is selected from a light-transparent material that is able to transmit UV light with wavelengths between 150 nm to 300 nm with as little loss as possible, and is able to transmit infrared light with wavelengths greater than 1 ⁇ m.
- the distal tip is designed to be straight or curved.
- the laser catheter is preferably brought into the eye across the anterior chamber in order to ablate the trabecular mechanism in front of Schlemm's canal, including its inner wall.
- the distal end of the laser catheter can also be curved, typically with angles of curvature between 6 and 10 mm, in order to minimize the risk of contact between the corneal endothelium and the lens.
- the fiber arrangement of the laser catheter should preferably be designed such that a partial area of the fiber arrangement can be used for image transmission. This presupposes that the fiber arrangement is composed of a large number of individual fibers, of which a partial fiber bundle can be used for optical image transmission. In this way, the material removal and also the positioning of the distal end of the laser catheter can be monitored and controlled on site and corrected accordingly by the surgeon.
- the distal end of the laser catheter can preferably have a plurality of light exit surfaces which are separate from one another and via which light can be emitted into the tissue to be treated at different application sites.
- through-channels can be created at different points in the trabecular mechanism without repositioning the optical fiber and moving it inside the eye. This also protects the eye from traumatic tissue irritation caused by a Repositioning of the laser catheter would be connected.
- the light application to the different light exit surfaces can either be serial or parallel. This is done either by moving a light source relative to the fiber input or by moving the fiber input relative to the light to be coupled.
- the laser catheter designed according to the invention is particularly suitable for the integration of a miniaturized endoscope device in which an additionally provided suction or rinsing channel is provided. In this way it is possible to immediately pass the ablated tissue material extracorporeally through the corresponding channel.
- a corresponding rinsing channel also serves for a clear field of vision, which is particularly necessary when the tissue removal is monitored visually.
- a feed unit which moves the light catheter distally in controlled steps is particularly advantageous.
- the operator can hand over the manual operation control to the feed automation, whereby the feed of the laser catheter can be carried out, for example, relative to the piercing point on the paracentesis within the eye.
- a feed unit can be formed, for example, by piezo actuators, which move the optical fiber arrangement step-by-step and in the smallest path sections into the interior of the tissue to be ablated due to their own contraction in length.
- a metal plate at the distal end at a distance from the light exit surface of the laser catheter, which generates pulsed light radiation which serves to dissolve the tissue located behind the metal plate.
- the metal plate is preferably attached parallel to the inclination of the light exit surface in order to get correspondingly close to the tissue of the trabecular mechanism to be removed.
- Fig. 2 handpiece of the laser catheter with protruding distally
- FIG. 3 a, b light exit surface of the fiber arrangement
- FIG. 4 a, b integration of the fiber arrangement into an endoscope device
- FIG. 5 distal end of the fiber arrangement with metal plate.
- Figure 1 shows the chamber angle, as already described above in relation to the prior art.
- the sponge-like trabecular structure T and the Schlemm's canal S behind it through which the aqueous humor is drained from the inside of the eye can also be seen from the illustration.
- the trabecular system which closes over time and is one of the causes of glaucoma, must be perforated so that the outflow of the aqueous humor is largely unimpeded.
- the handpiece 1 shows a handpiece 1 which enables the surgeon to precisely actuate the laser catheter 2 which passes axially through the handpiece 1.
- the handpiece 1 which has an outer contour ergonomically adapted to the hand of the surgeon, connects a flexibly designed light guide cable 3 to the laser catheter 2, which projects out of the handpiece 1 on the distal side.
- the flexibly trained Optical fiber 3 is connected to a corresponding light source (not shown), for example an excimer laser.
- the laser catheter 2 has a light exit surface 4 which is cut off obliquely to the longitudinal axis of the catheter and which is shown in cross section according to FIG. 3a.
- the intersection angle ⁇ , which the light exit surface includes with the fiber longitudinal axis, preferably has 37 ⁇ .
- the laser catheter is sheathed from a light-conducting fiber arrangement 5 and via an adhesive layer 6 with a support material 7 surrounding the fiber arrangement 5.
- the light-transparent fiber arrangement 5 is placed in the center of the laser catheter arrangement and is connected to the support material 7 via an adhesive layer 6, which is designed as an adhesive layer.
- the laser catheter Due to the slanted light exit surface, the laser catheter can be placed flush with the trabecular mechanism in the chamber angle of the eye and can come into direct contact there. Due to the beveled light exit end of the laser catheter, it lies flush against the tissue area to be treated without locally squeezing or compressing it, which would be the case with a laser catheter with a perpendicularly cut light exit end.
- FIG 4a shows an endoscope device which provides a plurality of proximal working areas 8, 9 and 10.
- the laser catheter 2 Through the working channel 8, the laser catheter 2, through the working channel 9 a visual optics 11 and through the Working channel 10 fed a flushing device 12.
- the laser catheter 2 At the distal end of the endoscope, the laser catheter 2 can be advanced distally.
- FIG. 4b shows two hollow cannulas 13, into which a plurality of laser catheters 2 - two or three laser catheters are shown in the figure - are introduced.
- the individual laser catheters 2 can be individually pushed out of the hollow cannula 13 distally and thus represent different light application foci. In this way, a large number of different tissue ablation sites within the eye can be achieved with the aid of only a single hollow channel that is guided into the interior of the eye.
- FIG. 5 shows the distal end of the laser catheter 2 with a metal plate 14 which is arranged distally away from the light exit surface. With the help of the metal plate 14, it is possible to generate shock waves through which tissue can be broken up.
