An endosurgical cutting instrument (100) includes a hollow tube (102) having a distal end with a radial slot (110) and an interior deflection surface, a push rod (104) extending through the tube and having a proximally directed sickle blade (108) coupled to its distal end, and a manual actuator (106) coupled to the proximal ends of the tube and push rod. The sickle blade is a curved member having a sharp concave edge (124) and a dull convex edge (122) and is coupled to the distal end of the push rod with its sharp concave edge facing the push rod. The blade is dimensioned such that it may be substantially completely contained within the tube. The push rod is oriented so that its distal end is free to move in a radial direction as it moves axially.

Instrument (100) de coupe endochirurgical qui comporte un tube creux (102) possédant une extrémité distale dotée d'une fente (110) radiale et une surface de déflexion interne, une tige de poussée (104) qui s'étend à travers le tube et est dotée d'une lame (108) en forme de faucille à orientation proximale couplée à son extrémité distale, et un actionneur manuel (106) couplé aux extrémités proximales du tube et de la tige de poussée. La lame en forme de faucille est un élément incurvé doté d'une arête concave (124) tranchante et d'une arête convexe (122) non tranchante. Elle est reliée à l'extrémité distale de la tige de poussée, son arête concave tranchante faisant face à ladite tige de poussée. La lame présente des dimensions telles qu'elle peut être complètement contenue à l'intérieur du tube. La tige de poussée est orientée de telle manière que son extrémité distale est libre de se déplacer dans une direction radiale lorsqu'elle se déplace axialement.
