[0002] At present, with the rapid progress of endoscopic diagnosis and treatment technology for the digestive tract, its application scope has expanded from the "mucosal surgery" field to the "serosal surgery" field. Nowadays, many abnormal tissues such as early digestive tract cancers, submucosal tumors, and polyps can be resected with the assistance of an endoscope. After resection, the resected specimen is usually taken out of the body together with the endoscope by using the suction function of the endoscope or through a snare. Ensuring the integrity of the obtained specimen is of extremely important significance for the accuracy of postoperative pathological diagnosis, evaluating the effect of endoscopic treatment, and providing guidance for subsequent treatment.

[0003] There are some problems in the recovery of existing specimens resected by endoscopic surgery for the digestive tract. Due to insufficient endoscopic suction or when passing through physiological stenosis sites such as the esophageal inlet, cardia, and anus, the specimen is likely to fall off. At the same time, there are also risks such as specimen deformation and fragmentation, which may lead to tumor metastasis and make the operation process less convenient. In addition, for multiple specimens in the same part, it may be necessary to insert the endoscope multiple times for collection, which is not only time-consuming but also laborious.

One end of the hand-held device 1 is connected to a sleeve 2, and a movable slot 3 is formed through the middle of one side of the outer periphery of the hand-held device 1;

[0019] A movable block 4 is slidably connected to the inner wall of the movable slot 3. One side of the movable block 4 is fixedly connected to a pull rod 5. One end of the sleeve 2 is provided with a recovery hole 7. The pull rod 5 movably passes through the inner wall of the recovery hole 7 and extends to one end of the outer periphery of the sleeve 2. One end of the outer periphery of the pull rod 5 is fixedly connected to a support ring 8, and the recovery bag 6 is fixedly connected to the outer periphery of the support ring 8;

[0020] The recovery bag 6 adopts a standard medical specimen collection bag. The diameter of the unfolded recovery bag 6 is 3 cm. Moreover, the maximum telescopic length of the sleeve 2 and the pull rod 5 is 240 cm, making the use range of the endoscopic recovery bag 6 wider;

[0021] By pushing and pulling the movable block 4, when the pull rod 5 slides in the movable slot 3 through the movable block 4, the support ring 8 at the end of the pull rod 5 and the recovery bag 6 sleeved on the outer periphery can be contracted to the end of the recovery hole 7, thereby tightening the opening at the end of the recovery bag 6. This realizes the tightening of the mouth of the recovery bag 6 containing the surgically removed sample, facilitating the complete closed recovery of the sample removed by the endoscopic surgery, and avoiding the sample falling off and the sample being squeezed and deformed or broken by the instrument during the process of carrying the sample. The recovery bag 6 can be unfolded together with the pull rod 5 and the support ring 8 by sliding the movable block 4, realizing the complete closed recovery of the specimen removed by the endoscopic surgery. At the same time, multiple samples at the same surgical site can be collected synchronously, avoiding the problem of inconvenient use caused by secondary endoscope insertion for recovery.

[0022] Among them, a handle 101 is integrally formed at one end of the hand-held device 1 away from the sleeve 2, and a mounting hole 102 is formed at one end of the hand-held device 1 close to the sleeve 2. One end of the sleeve 2 is connected to the inner wall of the connection hole 102.
