Patent

CA 2177829

A cutting and coagulating forceps includes a housing (10) with a protruding barrel (14), a pair of electro-cautery jaws (22, 24) which are closed by camming contact with the mouth of the barrel (14) when the jaws are retracted, and an independently movable blade (62) which passes between the jaws. The jaws are opened by squeezing a trigger (36) and the blade is advanced by pressing a lever (60) with the thumb. Forward blade movement is limited by a stop (52) whose position is a function of the jaw position, so that the blade cannot strike the jaws, yet always can travel a distance just short of the jaw tips.

L'invention concerne une pince de coupe et de coagulation. Cette pince se compose d'un logement (10) avec un canon saillant (14), une paire de mors d'électro-cautérisation (22, 24) qui sont fermés par un contact de type à cames avec la bouche du canon (14) lorsqu'ils sont rétractés, et une lame mobile (62) indépendante qui pase entre les mors. Ces derniers sont ouverts par pression exercée sur une détente (36), et la lame avance lorsque l'on presse un levier (60) avec le pouce. Le movement vers l'avant de la lame est limité par une butée (52) dont la position est fonction de celle du mors, de telle sorte que la lame ne peut pas frapper les mors, mais peut se déplacer sur une certaine distance sans entrer en contact avec les pointes de ces derniers.
