A surgical instrument for retrieving tissue from a patient. The instrument includes an elongated support tube having a proximal end and a distal end, and an elongated inner rod slidably and coaxially disposed within the support tube. The rod has a removable pouch attached thereto, wherein the pouch is initially disposed within the support tube, and wherein distal movement of the rod ejects the pouch from the tube. The instrument further includes a mechanism engaging the rod such that after the rod has initially been moved distally, the mechanism prevents proximal motion of the rod. The mechanism disengaging upon total ejection of the bag from the tube, and thereafter allows proximal and distal movement of the rod.
Il s'agit d'un instrument chirurgical qui sert à récupérer des tissus d'un patient. Cet instrument comprend un tube de support allongé présentant une extrémité proximale et une extrémité distale, et une tige interne allongée de manière coulissante et coaxiale à l'intérieur du tube de support. € la tige est fixée un sac amovible, placé initialement à l'intérieur du tube de support, et où le mouvement distal de la tige éjecte le sac du tube. Ledit instrument comprend en plus un mécanisme mettant la tige en prise, de sorte que, après que la tige ait été déplacée de manière distale, le mécanisme empêche le mouvement distal de la tige. Le mécanisme se libère lors de l'éjection complète du sac du tube, et permet par la suite le mouvement proximal et distal de la tige.
