ANTECEDENTES DE LA INVENCiÓN BACKGROUND OF THE INVENTION

En el ámbito de aplicación práctica de la invención, el de la cirugía ocular por vitrectomia, hasta la fecha se utiliza un pequeño trocar para dejar implantado un puerto en la parte del ojo conocido como "Pars Plana" (habitualmente 3 o mas puertos) para poder introducir a través de estos y de forma selectiva, o bien una fibra de luz, o bien infusión de suero para mantener forma y presión del globo ocular, o bien el instrumental adecuado para la cirugía, tal como un vitreotomo. In the practical scope of the invention, that of vitrectomy eye surgery, to date a small trocar is used to implant a port in the part of the eye known as "Pars Plana" (usually 3 or more ports) to to be able to introduce through these and selectively, either a light fiber, or infusion of serum to maintain shape and pressure of the eyeball, or the appropriate instruments for surgery, such as a vitreotome.

En la actualidad estos puertos mayormente metálicos suelen tener un calibre que varia desde 20 G a 27 G, siendo el calibre mas habitual el de 23G o 25 G Y de una longitud que ronda los 6mm, pudiendo ser valvulados o no para retener el contenido ocular. At present, these mostly metallic ports usually have a caliber that varies from 20 G to 27 G, with the most usual caliber being 23G or 25 G Y of a length that is around 6mm, being able to be valved or not to retain the ocular content.

Sin embargo, hay veces que este tipo de puertos no resultan lo mas adecuados posibles, ya que en ocasiones es necesario un mayor nivel de iluminación, o bien However, there are times when this type of port is not as adequate as possible, since sometimes a higher level of lighting is necessary, or

llevar a cabo una cirugía bimanual, con lo que es preciso añadir un cuarto puerto para adicionar otra luz. Perform bimanual surgery, which requires adding a fourth port to add another light.

DESCRIPCiÓN DE LA INVENCiÓN DESCRIPTION OF THE INVENTION

El dispositivo que se preconiza ha sido concebido para resolver la problemática anteriormente expuesta, de una forma sencilla pero de gran eficacia, permitiendo de forma simultánea y a partir del puerto, iluminar el interior del globo ocular así como introducir a través del mismo el instrumental quirúrgico. The device that has been recommended has been conceived to solve the problem described above, in a simple way but with great efficiency, allowing simultaneously and from the port, to illuminate the interior of the eyeball as well as to introduce the surgical instruments through it.

Para ello, el puerto que se preconiza en lugar de ser metálico, se obtiene a partir de fibra óptica, ya sea fibra de vidrio o plástico. For this, the port that is recommended instead of being metallic, is obtained from optical fiber, either fiberglass or plastic.

De forma mas concreta, este puerto tiene el calibre habitual en este tipo de cirugía de 20 a 27 G . More specifically, this port has the usual caliber in this type of surgery from 20 to 27 G.

En la parte que queda externa alojo a este puerto se le une un cable de fibra óptica tangencialmente al diámetro longitudinal del puerto, formando así un ángulo de alrededor de 30 grados entre el eje mayor del puerto y el eje longitudinal del cable de fibra óptica, dejando libre todo el interior del puerto para poder introducir a partir de dicho puerto el instrumental, tal como un vitrector, llevar a cabo la infusión de suero e incluso alguna sonda de luz. In the part that is external to this port is attached a fiber optic cable tangentially to the longitudinal diameter of the port, thus forming an angle of about 30 degrees between the major axis of the port and the longitudinal axis of the fiber optic cable, leaving all the interior of the port free to be able to introduce from this port the instruments, such as a vitrector, to carry out the infusion of serum and even some light probe.

La propia naturaleza del puerto perrqite transmitir la luz al interior del globo ocular, a través de sus paredes, proveniente del cable de fibra óptica y originada en la fuente de luz asociada a dicho cable, que habitualmente suele ser una luz Xenón, si bien podría ser cualquier otro tipo de fuente sin que ello afecte a la esencia de la invención. The very nature of the port allows transmitting the light inside the eyeball, through its walls, coming from the fiber optic cable and originating from the light source associated with said cable, which is usually a Xenon light, although it could be any other type of source without affecting the essence of the invention.

Obviamente el dispositivo de la invención puede participar en número mayor en los casos en los que sea necesario, con en el caso de cirugía bimanual, de manera que cada puerto puede estar unido a una fuente de luz propia por medio del comentado cable de fibra óptica, o bien todos los cables de fibra óptica Obviously, the device of the invention can participate in greater numbers in the cases in which it is necessary, with in the case of bimanual surgery, so that each port can be connected to its own light source by means of the aforementioned fiber optic cable , or all fiber optic cables

provenientes de los puertos estar asociados a una única fuente de luz común desde la que se divide el cable de fibra óptica para iluminar cada uno de los puertos. coming from the ports be associated with a single common light source from which the fiber optic cable is divided to illuminate each of the ports.

As can be seen in the aforementioned figures, the device that is recommended is constituted from a cylindrical body (1) of low height, which in correspondence with its lower face incorporates a long neck (2), of smaller diameter, being the device affected by a longitudinal hole (3), for passage of the instruments, serum injection or even additional lighting probes, with the particularity that, said body (1) is obtained from optical fiber, either fiberglass or plastic

Sobre la superficie exterior y perimetral del cuerpo (1) cilíndrico se establece un cable (4) o haz de fibra óptica, asociado a una fuente de iluminación, no representada en las figuras. On the outer and perimeter surface of the cylindrical body (1) a cable (4) or fiber optic beam is established, associated with a light source, not shown in the figures.

Tal y como se puede observar en las figuras, este cable (4) se dispone marginalmente al orificio (3), de manera que, el mismo no entorpece/obstrue en las labores de uso del puerto, al introducir instrumental a través de dicho orificio. As can be seen in the figures, this cable (4) is disposed marginally to the hole (3), so that it does not obstruct / obstruct the work of using the port, when introducing instruments through said hole .

Por su parte, la luz que se transmite a través del propio cable (4) de fibra óptica, On the other hand, the light that is transmitted through the fiber optic cable (4) itself,

, dada la propia naturaleza del puerto es a su vez transmitida a través de este, y consecuentemente a través de su cuello (2) inferior, con lo que la misma finalmente es proyectada sobre el interior del, globo ocular (5). , given the very nature of the port, it is in turn transmitted through it, and consequently through its lower neck (2), with which it is finally projected on the inside of the eyeball (5).

De acuerdo con el ejemplo de la figura 3, cuando sea necesario podrán implantarse viarios puertos, de modo que los cables (4) asociados a los mismos pueden centralizarse sobre una única fuente de iluminación, tal como una luz de Xenon, o indistintamente cada puerto podrá asociarse a una fuente de iluminación independiente. According to the example of figure 3, when necessary, several ports may be implanted, so that the cables (4) associated with them can be centralized on a single source of illumination, such as a Xenon light, or interchangeably with each port may be associated with an independent lighting source.

Se consigue de esta forma un dispositivo sumamente eficaz, con unas mejores prestaciones de iluminación, que permite reducir el numero de puertos utilizados por operación, reduciendo así las molestias al paciente. In this way an extremely efficient device is achieved, with better lighting performance, which allows reducing the number of ports used per operation, thus reducing patient discomfort.
