Definitions

  • the invention relates to electrical tool for erosion of the structure of the human intraocular lens anterior capsula, especially suitable for use during cataract surgery on the eye.
  • the tool for erosion of the structure of the anterior capsula of the human intraocular lens considerably reduces the above-mentioned disadvantages of the prior art.
  • the tool consists of an operational loop, flat closed curve-shaped with an area from 7 mm 2 to 115 mm 2 , formed by an elastic electrical wire with a cross section from 0.002 mm 2 to 0.5 mm 2 , mechanically connected to a holder formed by one or two hollow cylindrical bushings made of a dielectric material with minimum diameter of 0.5 mm and minimum length of 5 mm. At least one electrical lead goes through each bushing, one end of which is connected to the power supply with current controller and the other to the operational loop.
  • One aspect of the invention is that the operational loop and the leads have the same cross section and the same material.
  • the operational loop and the leads are made of different materials, the leads being made of a material with lower specific electrical resistance than the operational loop material.
  • Vet another aspect of the invention is that the operational loop and leads have different cross sections, the leads-in being made from wires with a larger cross section than that of the operational loop wire.
  • the advantage of the electrical tool for erosion of the structure of the anterior capsula of the human intraocular lens according to the invention is possibility of one-shot approximately round erosion of the structure of the anterior capsula of the human intraocular lens in a predefined shape of the operational loop.
  • the electrical tool for erosion of the structure of the anterior capsula of the human intraocular lens consists of an operational loop 1. made from platinum wire with a cross section 0.02 mm 2 .
  • the operational loop 1 is round-shaped with diameter 5.5 mm. This means that the operational loop 1, circle area is 23.74 mm 2 .
  • the operational loop _l is mechanically connected to a holder 2 formed by two hollow bushings 2 mutually longitudinally connected by an adhesive.
  • the bushings 2. are cylindrical-shaped of diameter 0.5 mm and length 50 mm and are made of ceramics.
  • One electrical platinum wire with a cross section 0.003 mm 2 goes through each of the bushings 2 and forms an electrical lead-in 4 . .
  • Each of the lead-in 4. wires has one end connected over the current controller converter 6 . formed by a thyristor frequency converter and a voltage transformer to the power supply 5 . and the other end to the operational loop JL.
  • the electrical tool for erosion of the structure of the anterior capsula of the human intraocular lens according to the invention is adapted to use in the formation of the circular hole in the anterior and posterior capsula of the human intraocular lens.

Abstract

L'invention concerne un outil électrique pour l'érosion de la capsule antérieure du cristallin humain. Cet outil comprend une boucle de travail (1) plate, courbe et fermée avec une surface de 7 mm2 à 115 mm2, constituée d'un fil métallique électrique résilient avec une section transversale de 0,002 mm2 à 115 mm2. Cette boucle est reliée mécaniquement à un support (3) constitué d'un ou de deux tubes cylindriques creux (3) faits en un matériau diélectrique avec un diamètre minimal de 0,5 mm et une longueur minimale de 5 mm. Au moins un conducteur électrique (4) est logé dans chacun des tubes (2), en ayant une extrémité connectée à une source de courant (5), via un régulateur (6) de courant et l'autre extrémité connectée à la boucle de travail (1).
