Title
(EN) DOUBLE ACTING ENDOSCOPIC SCISSORS WITH BIPOLAR CAUTERY CAPABILITY
(FR) CISEAUX ENDOSCOPIQUES A DOUBLE ACTION AVEC CAPACITE DE CAUTERISATION BIPOLAIRE
Abstract
(EN)
A double acting bipolar endoscopic scissors (10) includes a hollow tube (16) with an integral clevis (24) and a bipolar push rod extending therethrough. The tube (16) is rotatably mounted in a handle member which is provided with a manual actuation lever (14). The bipolar push rod includes a pair of spaced apart rods (32, 34) which are insulated along substantially their entire lengths by polypropylene sheaths (35, 35a), and which are insert molded in a distal insulating collar (46) near their distal ends, in a proximal insulating collar (36) near their proximal ends, and in plurality of non-conductive cylinders (35, 35a) therebetween. The distal collar includes a flattened distal portion (50) and the distal ends of the rods are bent approximately 90 degrees and exit the flattened portion. A pair of scissor blades (26, 28) are mounted in the clevis (24) with an axle screw and a nut and are insulated from the clevis and the axle screw.
(FR)
Cette invention se rapporte à des ciseaux endoscopiques bipolaires (10) à double action, qui comprennent un tube creux (16) avec un ÷illet solidaire (24) et une tige poussoir bipolaire s'étendant à travers lui. Le tube (16) est monté rotatif dans un manche, lequel est pourvu d'un levier d'actionnement manuel (14). La tige poussoir bipolaire se compose d'une paire de tiges espacées (32, 34), qui sont isolées essentiellement sur toute leur longueur par des gaines en polypropylène (35, 35a) et qui sont moulées par insertion dans une bride isolante distale (46) à proximité de leurs extrémités distales, dans une bride isolante proximale (36) à proximité de leurs extrémités proximales et dans plusieurs cylindres non conducteurs (35, 35a) entre ces deux extrémités. La bride distale comporte une partie distale aplatie (50) et les extrémités distales des tiges sont coudées approximativement à 90 degrés et sortent par la partie aplatie. Une paire de lames de ciseaux (26, 28) sont montées dans l'÷illet (24) avec une vis d'axe et un écrou et elles sont isolées de l'÷illet et de la vis d'axe.
