Definitions

  • Section 10 consists of a first partial hook 10 ⁇ and a second partial hook 10 ⁇ x , these partial hooks 10, 10 ⁇ each having essentially identical distal partial sections 11 ⁇ , 11 ⁇ ⁇ and proximal partial sections 12,
  • one of the proximal sections 12 ⁇ of the first partial hook 10 ⁇ is firmly connected to the hollow rod-shaped section 40, while the other proximal section 12 x ⁇ of the second partial hook 10 ⁇ compared to the first proximal section 12 ⁇ or to the first Partial hook 10 ⁇ can be pivoted such that the distal sections 11, 11 ⁇ can be moved apart from the folded position shown in FIG. 1 into a spread position shown in FIGS. 2-4.
  • the hook-shaped sections 10 and the pressure device 20, 20 ⁇ ⁇ can advantageously be made of electrically conductive material, in particular of metal, but which are insulated on their outer surfaces in such a way that a current flow into the tissue only at the contact points between the pressure elements 22 ⁇ , 22 ⁇ ⁇ and the distal sections 11 v , 11 ⁇ N can take place.
  • the parts shown, in particular the hook-shaped section 10 are coated with an anti-adhesive layer, which facilitates preparation.
  • the cutting device 30 is likewise preferably designed as an HF surgical instrument, that is to say has a cutting edge designed as an electrode, which is connected to an HF generator (not shown here).
  • the other pole of the HF generator is connected to at least one of the other instrument parts, namely one of the distal sections 11 v , 11 ⁇ x or a pressure element 22 ⁇ , 22 ⁇ ⁇ , so that an HF cutting current between the cutting edge of the cutting device 30 and this other pole can flow.

Abstract

On connaît déjà des instruments chirurgicaux à section en forme de crochet, présentant une section distale à extrémité libre, et une section proximale raccordée à un dispositif d'actionnement. L'invention est caractérisée en ce que les sections distale et proximale sont séparées le long d'un plan passant sensiblement par le milieu de la section distale, en vue de former des crochets partiels, et en ce que ces derniers sont rendus mobiles, par le dispositif d'actionnement, avec un plan extensible, de façon que le crochet puisse s'écarter en deux parties.
