摘要：
A re-openable specimen extraction bag comprising a catheter, a pull rod, a flexible body, and a specimen bag. The catheter is provided with a cavity being run through in the axial direction. The pull rod is arranged within the cavity and can slide in the axial direction. The specimen bag is provided with an opening. The flexible body is arranged at the headend of the pull rod and arranged along the opening. The two can slide relative to each other. The flexible body can enter the headend of the catheter as the pull rod slides to tighten the opening, thus closing the specimen bag, and can be separated from the catheter as the pull rod slides, and stretches into a ring upon separation to open the opening, thus opening the specimen bag. The specimen bag can be repeatedly opened and closed as the pull rod slides. This implements repeated opening of the specimen bag, facilitates multiple placements of specimens, facilitates surgery time saving, and is easy and practical. A handle can be removed from the pull rod rapidly to facilitate separation of the specimen bag from the catheter. This effectively prevents additional injuries due to the pull rod being over inserted. A medical worker is allowed to hold the opening of the specimen bag in a direction that facilitates placement of specimens.L'invention concerne une poche d'extraction d'échantillon pouvant être rouverte, celle-ci comprenant un cathéter, une tige de traction, un corps souple et une poche d'échantillon. Le cathéter comporte une cavité traversée dans la direction axiale. La tige de traction est disposée dans la cavité et peut coulisser dans la direction axiale. La poche d'échantillon est pourvue d'une ouverture. Le corps souple est agencé au niveau de l'extrémité de tête de la tige de traction et le long de l'ouverture. Les deux peuvent coulisser l'un par rapport à l'autre. Le corps souple peut entrer dans l'extrémité de tête du cathéter à mesure que la tige de traction coulisse pour serrer l'ouverture, ferman
