Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a disposable object-taking bag with an easily adjustable opening. Background Art

[0002] The disposable retrieval bag is specially developed for the needs of minimally invasive surgical operations such as laparoscopy. It is used to remove foreign bodies removed during surgery at one time. Usually, the diseased tissue after removal is removed by an instrument, and then put into the disposable retrieval bag and pulled out of the body. In this way, the contact between the diseased tissue and the healthy tissue is effectively prevented, and pathological residues are avoided. It can not only greatly facilitate the doctor's surgical operation and reduce the difficulty of the operation, but also be beneficial to the patient's postoperative recovery, reduce the risk of postoperative infection, and save a lot of hidden treatment costs for the patient. The existing retrieval bag generally opens and contracts the retrieval bag by directly pushing and pulling. For example, Chinese patent CN209136819U discloses a disposable retrieval bag that is easy to adjust the opening, including a sleeve rod, wherein: a handle is provided at one end of the sleeve rod, a telescopic screw is provided in the sleeve rod, one end of the telescopic screw passes through the handle and the push block and is fixedly connected to the positioning block, and the other end is fixedly connected to the telescopic ring, and the telescopic ring is provided with a retrieval bag, and an internal thread is provided in the push block, and the push block is connected to the telescopic screw by a thread. The above patent realizes the smooth and rapid opening and contraction of the extraction bag through the cooperation of the pushing block and the telescopic screw, thereby avoiding damage to tissues caused by the extraction bag opening too quickly or too large. However, the size of the opening and contraction of the extraction bag cannot be accurately confirmed during the operation. If the opening of the extraction bag is too large, it is easy for the diseased tissue to fall out, and if it is too small, it is difficult to put the diseased tissue in, which increases the difficulty of the operation. At the same time, if the opening of the extraction bag is too large, it will cause damage to human tissues, increase the risk of surgery, and increase the pain of patients.

[0003] Therefore, it is necessary for those skilled in the art to provide a disposable retrieval bag with an easily adjustable opening, so that the size of the opening of the retrieval bag is controllable and can be visually seen by the operator, thereby ensuring the stability and accuracy of the operation.
