Abstract

A thoracoscopic lung resection sample extraction device and method. The invention relates to the field of medical devices, in particular to a device and method for taking out specimens of thoracoscopic lung resection. Provided are a simple in structure, convenient to adjust and reliable in operation device and method for taking out specimens of thoracoscopic lung resection. When the present invention is in operation, an auxiliary sheath is hinged on the outside of one end of the main sheath used for the bag body to protrude, and the bottom of the auxiliary sheath is respectively provided with a push-pull rope and a pair of elastic ropes; under normal conditions, the retrieval assembly is located at Inside the main sheath; when picking up the object, push the tube to push the picking assembly out of the main sheath, so that a pair of elastic ropes connecting the two ends of the mouth of the bag are stretched to open the bag; because a pair of elastic ropes are connected to the auxiliary sheath, The auxiliary sheath tube is connected with a push-pull rope, which is convenient to drive the auxiliary sheath tube to swing through the push-pull action of the push-pull rope, thereby driving the adjustment of the angle of the bag body, so that the specimen can be reliably put into the bag body. The invention is convenient for processing and reliable in operation.

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 2020.07.31. The announcement number is CN211131191U, and the name is "Laparoscopic Surgery Specimen Retrieval Bag", which discloses that in the current clinical ...
