Definitions

  • the free or front ends of the expansion limbs are in the direction of the apex of the loop in front of the region of the largest opening width of the loop.
  • a preferred development is also seen in that at least the loop loop has a plurality of spaced-apart local thickenings and / or spaced, loop-inwardly directed hooks.
  • the thickenings or hooks can be arranged as needed in the effective as an active electrode length sections and / or the electrically insulated lengths.
  • the electrically insulating sheathing as an electrically insulating cover only in a limited circumferential range of the ski core or of the sling core cross section. It would thus be conceivable for the lateral surface of the loop core to be electrically conductively free at least circumferentially at the peripheral side facing the loop core section of the loop opening and at the peripheral edge facing away from the loop opening at least in the circumferential direction has an electrically insulating cover.
  • the lateral surface of the ski core to be continuously electrically conductively exposed in the circumferential direction relative to the loop core cross-section at the circumferential half in the circumferential direction, and at the circumferential half facing away from the loop opening, carries an electrically insulating cover.
  • This possible development relates on the one hand to the loop loop and the expansion leg, but can also be applied to the tension elements as needed.

Abstract

L'invention concerne un instrument chirurgical (20) comportant un élément de traction/poussée (2) guidé dans une gaine (1), cet élément étant destiné à transmettre une force de traction/poussée d'un dispositif d'actionnement (3) disposé à une extrémité de la gaine (1) à une boucle (4) disposée à l'autre extrémité de la gaine (1), afin de déplacer la boucle (4) d'une position de stockage, dans laquelle la boucle (4) s'étend dans la gaine (1) en position d'extension, à une position d'utilisation dans laquelle l'ouverture (5) écartée de la boucle (4) est située devant la gaine (1), et inversement. La boucle (4) présente deux jambes d'écartement (6) écartées en forme de V et situées partiellement devant et dans la gaine en position d'utilisation, ces jambes d'écartement (6) présentant une plus grande résistance à la flexion, au moins dans une direction perpendiculaire au plan d'ouverture (5'), qu'un arc de boucle (7) connectant les extrémités libres respectives (61) des jambes d'écartement. L'élément de traction/poussée (2) est électroconducteur. L'invention vise à perfectionner cet instrument chirurgical de manière avantageuse. À cet effet, au moins une première section longitudinale (21) de l'arc de boucle (7) située sur un côté longitudinal de la boucle (4) dans la position de stockage présente un revêtement (23) électriquement isolant ou est constituée d'un matériau électriquement isolant, et au moins une deuxième section longitudinale (22) de l'arc de boucle (7) située sur l'autre côté longitudinal de la boucle (4) dans la position de stockage est électroconductrice, ne présente pas de revêtement électriquement isolant et est reliée de façon électroconductrice à l'élément de traction/poussée (2) au moyen d'au moins une jambe d'écartement (6).
