A laparoscopic surgery instrument placing bag, comprising a functional block (1), wherein the interior of the functional block (1) is separately provided with a functional cavity (3) and power cavities (2)； the inner wall of the functional cavity (3) is fixedly communicated with the upper surface of the functional block (1)； the inner walls of multiple power cavities (2) all are fixedly communicated with the inner wall of the functional cavity (3)； the inner wall of the functional cavity (3) is slidably connected with a power plate (4)； the upper surface of the power plate (4) is fixedly connected with push rods (5)； the surfaces of multiple push rods (5) all are slidably inserted into the inner walls of the corresponding power cavities (2). During actual use, medical instruments having long rods have different lengths, and multiple second functional rods (23) of the laparoscopic surgery instrument placing bag can slide in corresponding first functional rods (13) by means of movable blocks (22), so that a distance between a first functional cylinder (11) and a second functional cylinder (14) is changed； when the operating handle of the medical instrument having the long rod is fixed by a first protective block (15) and a second protective block (18), a transmission rod is fixed by multiple fixing blocks (8), and the degree of expansion and contraction of the second functional rods (23) in the first functional rod (13) is also determined and cannot be casually changed.La présente invention concerne une poche de mise en place d'instrument de chirurgie laparoscopique, comprenant un bloc fonctionnel (1), dans lequel l'intérieur du bloc fonctionnel (1) est pourvu séparément d'une cavité fonctionnelle (3) et de cavités d'alimentation (2) ； la paroi interne de la cavité fonctionnelle (3) communiquant de manière fixe avec la surface supérieure du bloc fonctionnel (1) ； les parois internes des multiples cavités d'alimentation (2) communiquant toutes de manière fixe avec la p
