Definitions

  • a refractor is often formed as a substantially rectangular body of stainless steel, one leg of which is flattened rounded and the other leg is thickened as a substantially cylindrical handle is formed.
  • the hook element is a replaceable disposable element provided, so that a subsequent cleaning and sterilization is eliminated.
  • the two-part design of the retaining hook is disadvantageous. Since the entire force must be transmitted via the coupling between the retaining hook and the handle, there is a risk that the handle detaches from the retaining hook during a surgical procedure and obstructs a treating physician. In addition, only a very small part of the surgical field can be irradiated. Furthermore, the handle must be sterilized after each use, which greatly reduces the life expectancy of the energy storage and the diode. In particular, the optical properties of a light exit surface of the handle can be attacked during sterilization, so that with increasing useful life less and less light can be coupled into the light guide strand of the hook element.
  • the handle portion, the hook portion and the light guide are integrally formed, eliminating a mounting of the light guide on the hook portion of the refractor. Furthermore, there is no danger of unintentional detachment of the light guide from the hook section. It is also possible to form the grip portion, the hook portion and the light guide so that no gaps between the grip portion, the hook portion and the light guide remain, which brings advantages in terms of hygiene advantages.
  • the refractor can be designed as a disposable part.
  • connection region is designed in the form of a coupling element which extends in a straight line parallel to the longitudinal extension of the grip section.
  • the coupling element is arranged on the side of the grip portion which faces away from the hook portion.
  • the coupling element has a trapezoidal cross-section. According to one embodiment, several
  • Coupling elements provided, which are opposite to the handle portion in pairs.
  • connection region is formed adjacent to the hook section on the grip section.
  • the coupling element is a projection. According to an alternative embodiment, the coupling element is a recess.
  • the light guide is formed from polymethylmethacrylate, polycarbonate, polyetheretherketone or quartz glass. These materials have a good photoconductive property, since total reflection can occur at interfaces.
  • the grip portion and the hook portion are formed of polymethylmethacrylate, polyetheretherketone or polycarbonate. These materials have good heat resistance, optical clarity, high mechanical strength and impact resistance. In addition, these materials allow the production of the light guide and handle portion and hook portion of the same material.

Abstract

L'invention concerne un rétracteur médical (1) comprenant une partie poignée (2) et une partie crochet (3). La partie poignée (2) est réalisée au moins sur certaines parties sous la forme d'un corps creux, lequel comporte une cavité (4). La partie crochet (3) comprend au moins un guide de lumière (5) pourvu d'une surface d'entrée de lumière et d'une surface de sortie de lumière. La partie poignée (2), la partie crochet (3) et le guide de lumière (5) sont réalisés d'une seule pièce. La surface d'entrée de lumière (51) du ou des guides de lumière (5) est située dans la cavité (4) formée dans la partie poignée (2), ou dans l'alignement d'une paroi intérieure de la cavité (4) formée dans la partie poignée (2). La surface de sortie de lumière (52) du ou des guides de lumière (5) est orientée en éloignement de la partie poignée (2). Le guide de lumière (5) présente une section transversale (D), laquelle est constante ou augmente dans la zone de la surface de sortie de lumière (52) en direction de la surface de sortie de lumière (52). L'invention concerne en outre un éclairage pour le rétracteur médical, ledit éclairage étant situé dans la cavité qui est formée dans la partie poignée.
