Objeto de Ia invenciónObject of the invention
La presente invención se refiere sistema para Ia operación de desprendimientos de retina, y más concretamente, utilizando Ia técnica de retinopexia transconjuntival.The present invention refers to a system for the operation of retinal detachments, and more specifically, using the transconjunctival retinopexy technique.
Antecedentes de Ia invenciónBackground of the invention
Actualmente son conocidas diversas técnicas para tratar de aplicar Ia retina cuando se ha producido un desprendimiento de retina. Una de estas técnicas es el cerclaje escleral con o sin indentación y con Ia punción de Ia bolsa retiniana por vía externa escleral, sin embargo esta técnica puede crear miopía o aumentarla, como también comprimir las venas vorticosas y provocar isquemia en el segmento anterior.Various techniques are currently known to try to apply the retina when a retinal detachment has occurred. One of these techniques is scleral cerclage with or without indentation and with the puncture of the retinal pouch by external scleral route, however this technique can create myopia or increase it, as well as compress the vorticose veins and cause ischemia in the anterior segment.
Otra técnicas conocidas consisten en Ia aplicación de gases intraoculares para provocar un tamponamiento del regma y Ia aplicación de Ia retina, pero estas técnicas pueden provocar, entre otras complicaciones, el aumento de Ia tensión ¡ntraocular, y Ia vitrectomía con Ia aplicación de gases, aceite de silicón, crioterapia o endoláser, que también puede presentar complicaciones como el aumento de Ia tensión ocular, hemorragias, desprendimiento coroideo, catarata, endoftalmitis, y roturas retinianas iantrogénicas entre otras.Other known techniques consist in the application of intraocular gases to cause a buffering of the regimen and the application of the retina, but these techniques can cause, among other complications, the increase in intraocular tension, and vitrectomy with the application of gases, silicone oil, cryotherapy or endolaser, which can also present complications such as increased ocular tension, hemorrhages, choroidal detachment, cataract, endophthalmitis, and iatrogenic retinal tears, among others.
Descripción de Ia invenciónDescription of the invention
El sistema de Ia invención presenta unas particularidades constructivas que permiten, mediante Ia técnica de retinopexia transconjuntival, agilizar Ia cirugía del desprendimiento de retina regmatogénico provocado por Ia miopía o traumatismos oculares, disminuir los riesgos de complicaciones como son las infecciones intraoculares y reaplicar Ia retina desprendida por vía transconjuntival, sin necesidad de realizar técnicas más invasivas como Ia vitrectomía con tamponamientos (aire, gas o aceite de silicón); o Ia realización de un cerclaje escleral.The system of the invention has constructive features that allow, by means of the transconjunctival retinopexy technique, to speed up the surgery of the detachment of regmatogenic retina caused by myopia or ocular trauma, reduce the risks of complications such as intraocular infections and reapply the detached retina by transconjunctival route, without the need for more invasive techniques such as Ia vitrectomy with tamponings (air, gas or silicone oil); or the realization of a scleral cerclage.
El sistema para Ia operación de desprendimientos de retina; objeto de Ia invención, comprende: - un dispositivo de aspiración controlada, alojado en una carcasa o consola principal y provisto de: un pulsador de mando para el control del dispositivo de aspiración, un dispositivo regulador de Ia potencia de aspiración y de un conducto de aspiración y - un cabezal extrusor o aspirador provisto de: una boca para Ia conexión del conducto de aspiración procedente del dispositivo de aspiración controlada, un indentador escleral en el interior del cual se encuentra dispuesta una aguja para Ia aspiración del líquido subretiniano por vía transconjuntival, un botón para Ia activación de Ia aguja hacia una posición sobresaliente o hacia una posición retraída, y un reservorio interior, desmontable, para Ia recogida del líquido de aspiración subretiniana.The system for the operation of retinal detachments; object of the invention, comprises: - a controlled suction device, housed in a main housing or console and provided with: a control button for the control of the suction device, a device regulating the suction power and a conduit of aspiration and - an extruder or aspirator head provided with: a mouth for the connection of the aspiration duct from the controlled aspiration device, a scleral indenter inside which a needle is disposed for the aspiration of the subretinal liquid by transconjunctival route, a button for the activation of the needle towards an outstanding position or towards a retracted position, and a removable inner reservoir for the collection of the subretinal suction fluid.
Este sistema, indicado para Ia retinopexia, permite realizar una aspiración lenta, o extrusión, regulada del líquido subretiniano por vía transconjuntival.This system, indicated for retinopexy, allows a slow aspiration, or extrusion, regulated of the subretinal fluid by transconjunctival route.
Para permitir un control cómodo del sistema se ha previsto que el pulsador de mando está dispuesto en un pedal de accionamiento.In order to allow a comfortable control of the system, it is foreseen that the control button is arranged in a drive pedal.
El dispositivo regulador de Ia potencia de aspiración está constituido por un potenciómetro digital, incorporado en Ia consola del dispositivo de aspiración, que también está proviso de una pantalla indicadora de Ia potencia de aspiración aplicada y ajustada previamente a través del potenciómetro.The regulating device of the suction power is constituted by a digital potentiometer, incorporated in the console of the suction device, which is also provided with a display indicating the suction power applied and previously adjusted through the potentiometer.
En Io que refiere al cabezal extrusor cabe destacar que tanto del indentador como Ia aguja son desmontables para su esterilización y reutilización. El reservorio de líquido subretiniano del cabezal extrusor está provisto de un tapón para Ia salida de fluidos.In what refers to the extruder head, it should be noted that both the indenter and the needle are removable for sterilization and reuse. The subretinal liquid reservoir of the extruder head is provided with a plug for the outlet of fluids.
Este sistema es utilizado con Ia técnica Retinopexia Transconjuntival, técnica que produce Ia reaplicación de Ia retina mediante Ia introducción de una finísima aguja por vía escleral y Ia aspiración del líquido subretiniano, siendo comandada esta aspiración por medio del pedal conectado a Ia consola del sistema de aspiración o extrusión.This system is used with the Transconjunctival Retinopexy technique, a technique that produces the reapplication of the retina by means of the introduction of a very fine needle by the scleral route and the aspiration of the subretinal fluid, this aspiration being commanded by means of the pedal connected to the console of the system of aspiration or extrusion.
Para realizar esta técnica con el sistema de Ia invención, es preciso ubicar el desprendimiento de retina, preferentemente mediante el Oftalmoscopio Binocular Indirecto (OBI) con una lupa de +20 dioptrías, realizado este paso, se emplea la punta del extrusor con el ¡ndentador para provocar un blanco a Ia presión en el polo posterior y de esta forma llegar a indentar Ia zona de Ia bolsa del desprendimiento de retina, una vez conseguido el blanco a Ia presión en el área del desprendimiento de retina y teniendo Ia seguridad que nos encontramos debajo de Ia bolsa, se procede a oprimir el botón lateral del extrusor para que se introduzca Ia aguja de aspiración dentro del ojo (por debajo del desprendimiento de retina), visualizando siempre Ia aguja, posteriormente se comienza a pisar el pedal para iniciar la extrusión o aspiración del líquido subretiniano (Ia potencia de extrusión será regulada directamente en Ia consola por medio del potenciómetro). Posteriormente se aspira el líquido subretiniano hasta lograr que Ia retina se aplique (a medida que esto vaya sucediendo se va retirando Ia aguja de aspiración poco a poco para no provocar otra rotura en Ia retina). Aplicada la retina, se quita el pié del pedal de extrusión y se oprime el botón del extrusor, para que Ia aguja de aspiración se introduzca nuevamente dentro de Ia punta del extrusor y por último se retira el extrusor de Ia esclera.To perform this technique with the system of the invention, it is necessary to locate the retinal detachment, preferably by means of the Indirect Binocular Ophthalmoscope (OBI) with a magnifying glass of +20 diopters, performed this step, use the tip of the extruder with the indenter to cause a target at the pressure on the posterior pole and thus reach the indentation area of the retinal detachment bag, once the target has been achieved at the pressure in the area of detachment of retina and having the security that we are under the bag, we proceed to press the side button of the extruder so that the aspiration needle is inserted into the eye (below the retinal detachment), always visualizing the needle, subsequently the pedal begins to step on to start extrusion or suction of the subretinal liquid (the extrusion power will be regulated directly in the console by means of the potentiometer). Subsequently, the subretinal fluid is aspirated until the retina is applied (as this happens, the aspiration needle is gradually removed so as not to cause another rupture in the retina). Once the retina is applied, the foot of the extrusion pedal is removed and the extruder button is pressed, so that the aspiration needle is inserted back into the tip of the extruder and finally the extruder is removed from the sclera.
Realizada Ia Retinopexia Transconjuntival y continuando Ia observación bajo el OBI con Ia lupa, se procede a sellar Ia rotura retiniana por ejemplo con Ia aplicación de frío (crioterapia) o con láser de argón.Performed the Transconjunctival Retinopexy and continuing the observation under the OBI with the magnifying glass, the retinal rupture is sealed, for example with the application of cold (cryotherapy) or with argon laser.
Este sistema permite por tanto: reaplicar Ia retina desprendida por vía transconjuntival, sin necesidad de realizar técnicas más invasivas como Ia vitrectomía con tamponamientos (aire, gas o aceite de silicón); o la realización de un cerclaje escleral, y realizar un procedimiento más rápido y con menos riesgo de complicaciones.This system therefore allows: to reapply the detached retina by transconjunctival route, without the need for more invasive techniques such as vitrectomy with tamponings (air, gas or silicone oil); or performing a scleral cerclage, and performing a faster procedure and with less risk of complications.
