Title (EN) SURGICAL INSTRUMENT FOR AN ENDOSCOPE
(FR) INSTRUMENT CHIRURGICAL POUR UN ENDOSCOPE
Abstract: front page image
(EN)The invention is concerned with endoscopic surgical procedures involving positioning of surgical instruments, including snares, forceps, knives and electrodes within the body. One problem in such operations has been poor control over the movement of the instrument. This problem is critical where the procedure must be performed without direct visualization. Applicant solves the problem by providing, with the lumen of a tubular member (56), a tool (52) formed of a distal working end (58) and a longitudinal control wire (60). The control wire (60) is flat, helically twisted and sized to radially stabilize the position of the control wire within the lumen. The distal end of the tubular member has a predetermined bend (82), with a channel (86) cut therein in a manner selected to enable the working end of the tool to be automatically moved into the channel and thus reliably extended from a side of the distal end of the catheter.
(FR)Procedes de chirurgie endoscopique concernant le positionnement d"instruments chirurgicaux, tels que des serre-noeuds, des pinces, des bistouris et des electrodes dans le corps. Un probleme pose dans de telles operations etait le mauvais controle du mouvement de l"instrument. Ce probleme est critique lorsque le procede doit etre applique sans vision directe. Il est resolu en montant dans le passage d"un organe tubulaire (56), un outil (52) forme d"une extremite de travail distale (58) et d"un fil metallique de commande longitudinal (60). Le fil de commande (60) est plat, enroule en helice et dimensionne pour stabiliser radialement la position du fil de commande dans le passage. L"extremite distale de l"organe tubulaire possede une courbure predeterminee (82), avec un canal (86) decoupe dans celle-ci d"une maniere choisie pour permettre a l"extremite de travail de l"outil d"etre deplacee automatiquement dans le canal et ainsi etre allongee de maniere sure a partir d"un cote de l"extremite distale du catheter.
