Definitions

  • the present invention refers to a system for the operation of retinal detachments, and more specifically, using the transconjunctival retinopexy technique.
  • 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.
  • 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.
  • 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.
  • This system indicated for retinopexy, allows a slow aspiration, or extrusion, regulated of the subretinal fluid by transconjunctival route.
  • control button is arranged in a drive pedal.
  • 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.
  • 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.
  • Transconjunctival Retinopexy 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.
  • 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).
  • OPI Indirect Binocular Ophthalmoscope
  • 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).
  • 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.
  • the retinal rupture is sealed, for example with the application of cold (cryotherapy) or with argon laser.
  • 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.
  • 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.
  • Figure 1 shows a schematic perspective view of an embodiment of the system for the operation of retinal detachments.
  • Figure 2 shows an enlarged detail in elevation of the aspirator or extruder head in rest position, with the needle hidden inside the indenter
  • Figure 3 shows a view analogous to the previous one with the activation button of the needle pressed and with the needle in an outstanding position.
  • the system comprises a controlled suction device (1), housed in a main housing or console, and which is provided with a device (1 1) regulating the suction power, namely a digital potentiometer, of a screen (12) for the visualization of the applied suction power and of a switch (13) on and off.

Abstract

Le système de l'invention comprend un dispositif (1) d'aspiration commandé auquel se connecte un embout (4) d'extrudeuse ou d'aspirateur, au moyen d'un conduit d'aspiration (14). Ce dispositif (1) comprend: un bouton poussoir de commande (2), un dispositif (1) de régulation de puissance d'aspiration et un écran (12) permettant de visualiser la puissance d'aspiration appliquée. L'embout (4) comprend: un dispositif d'indentation sclérale (31), une aiguille (32) destinées à l'aspiration du liquide sous-rétinien, un bouton destiné à actionner l'aiguille jusqu'à une position sortie ou jusqu'à une position rétractée, et un réservoir intérieur (33) destiné à récupérer le liquide aspiré.
