Problems solved by technology
[0004] However, due to the small space in the thoracic cavity, the resected lung specimen tissue is relatively large. After the extraction bag is opened, the angle at which the specimen can be put into the extraction bag is limited due to the non-adjustable angle, which increases the difficulty of operation.

The present invention discloses an object taking device and method for thoracoscope pulmonary resection specimens. The present invention relates to the field of medical devices and particularly to anobject taking device and method for thoracoscope pulmonary resection specimens. The object taking device for the thoracoscope pulmonary resection specimens is simple in structure, convenient to adjustand reliable in operation. In a working process, an auxiliary sheath tube is hinged to an outer side of one end, used for stretching out of the bag body, of a main sheath tube, and a push-pull rope and a pair of elastic ropes are arranged at a bottom part of the auxiliary sheath tube; in a conventional state, the object taking assembly is located in the main sheath tube; during object taking, a push tube pushes the object taking assembly out of the main sheath tube, so that the pair of the elastic ropes connected with two ends of an opening part of the bag body are unfolded to open the bag body; and due to the fact that the pair of elastic ropes is connected with the auxiliary sheath tube, and the auxiliary sheath tube is connected with the push-pull rope, the auxiliary sheath tube can bedriven to swing conveniently through push-pull actions of the push-pull rope, angles of the bag body are driven to be adjusted, and the specimens can be reliably placed in the bag body. The object taking device is convenient for processing and reliable to operate.
Description
technical field [0001] The invention relates to the field of medical devices, in particular to a device and method for taking out specimens of thoracoscopic lung resection. Background technique [0002] Pathological examination is to use surgical methods to collect small pieces of tissue from the diseased part of the body, conduct histopathological examination, find out the evidence of pathological changes, and make a confirmatory diagnosis of the disease in conjunction with the clinic. It is a direct and effective examination method. . [0003] In actual operation, the retrieval bag is a supporting product of surgical instruments under thoracoscopic surgery, and is used to remove biopsy samples from the surgical area during surgery. For example, the State Intellectual Property Office authorized the announcement on July 31, 2020. The announcement number is CN21131191U, and the name is "Specimen Retrieval Bag for Endoscopic Surgery". The outer sheath tube is inserted into t...
