Technical Field

The utility model relates to the technical field of medical treatment, in particular to a double-joint endoscope object taking device for a single-hole thoracoscope.

Background

At present, minimally invasive thoracic surgery is very popular, wherein single-hole thoracoscopic surgery occupies more than 70% of thoracoscopic surgery in many medical centers, and compared with thoracoscopic surgery with open chest and multi-hole thoracoscopic surgery, single-hole thoracoscopic surgery has smaller incision, lighter wound and higher life quality after operation of patients. The incision for single hole thoracoscopic surgery is about 3 cm long and all instruments need to be accessed through the same incision (as in fig. 1, instruments 1', 2', 3', 4' all come from the same incision 5 '). In single-hole thoracoscopic surgery, specimen extraction is an important step in the surgical procedure, and a laparoscopic extractor is required to be cut to extract a mark.
