DETAILED DESCRIPTION OF THE INVENTION

[0022] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are exemplary and are not intended to limit the scope of the present invention. In addition, in the following description, the descriptions of well-known structures and technologies are omitted to avoid unnecessarily confusing the concepts of the present invention.

[0023] As Figure 1-2 shown, an easily detachable endoscopic retrieval bag proposed by the present invention includes a grip rod 1, and a pull rod 2 is slidably sleeved on the grip rod 1;

[0024] One end of the pull rod 2 is connected to an annular elastic member 4 through a positioning member 3;

[0025] A fetching bag 7 is sleeved on the bottom of the annular elastic member 4;

[0026] A channel is formed inside the annular elastic member 4. A notch is formed on one side of the annular elastic member 4 and extends outward. One end of the annular elastic member 4 is a closed end (the other end forms an opening). A pulling member 5 is arranged in the channel of the annular elastic member 4, and the pulling member 5 passes through the opening of the annular elastic member 4 and is connected with a pull rope 6;

[0027] One end of the pull rope 6 extends into the pull rod 2 and extends out of the pull rod 2.

[0028] In an optional embodiment, the positioning member 3 includes a positioning pin 31, a spring 32 and a mounting ring 33. The mounting ring 33 is movably sleeved on the pull rod 2 and the annular elastic member 4. The insertion end of the positioning pin 31 slides into the inside of the mounting ring 33 and the annular elastic member 4. The spring 32 is movably sleeved on the positioning pin 31. One end of the spring 32 is fixedly connected to the T-shaped end of the positioning pin 31, and the other end of the spring 32 is fixedly connected to the outer periphery of the mounting ring 33.

[0029] It should be noted that under the action of the spring 32, it is beneficial to limit and release the limit of the positioning pin 31.

[0030] In an optional embodiment, a pull ring is fixedly connected to the T-shaped end of the positioning pin 31.

[0031] It should be noted that under the action of the pull ring, it is beneficial to hold the position of the grip rod 1.
