Detailed Description

In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the drawings of the embodiments of the present invention are combined below to clearly and completely describe the technical solution of the embodiments of the present invention. It is to be understood that the embodiments described are only some of the embodiments of the present invention, and not all of them. All other embodiments, which can be obtained by a person skilled in the art without any inventive work based on the described embodiments of the present invention, belong to the protection scope of the present invention. Unless defined otherwise, technical or scientific terms used herein shall have the ordinary meaning as understood by one of ordinary skill in the art to which this invention belongs. As used herein, the word "comprising" and similar words are intended to mean that the element or item listed before the word covers the element or item listed after the word and its equivalents, but does not exclude other elements or items.

As shown in fig. 1 to 5, the specimen bag for endoscopic surgery of the present invention comprises a specimen bag body 1, wherein the specimen bag body 1 is conical, a reinforcing round rib 11 is formed at the edge of the bag mouth of the specimen bag body 1, and a push rod positioning groove 12 is formed in the center of the inner side of the bottom of the specimen bag body 1; the specimen bag body 1 is connected with the pushing rod 2 through the pushing rod positioning groove 12;

the edge of the bag opening of the specimen bag body 1 is also provided with a tying pull rope 3, and the tying pull rope 3 is positioned at the inner side of the reinforced circular rib 11 and is arranged in parallel with the reinforced circular rib 11; the tying stay cord 3 is wound around the bag mouth of the label bag body 1 for one circle, and the two ends of the tying stay cord are positioned through the tying stay cord knot 4; the fixed end of the tying pull rope 3 is fixedly connected with a tying pull rope knot 4, and the free end of the tying pull rope 3 extends out of a rope threading hole of the tying pull rope knot 4 and can move relative to the tying pull rope knot 4; when the tying stay cord knot 4 is stressed, the tying stay cord knot 4 can move relative to the tying stay cord 3, so that the bag opening of the specimen bag body 1 is tied tightly;

in order to ensure that the outer diameter of the specimen bag body 1 in the storage state is as small as possible, the opening of the specimen bag body 1 is an inclined plane, namely, an included angle α is formed between the opening of the specimen bag body 1 and the rotation center of the specimen bag body 1, so that the specimen bag body 1 is in an inclined cone shape;

meanwhile, the bag opening is an inclined plane, so that the specimen bag body 1 can be kept to be opened as large as possible in an opening state, and a doctor can conveniently place tissues cut by an operation.
