Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a clinical specimen extractor for thoracic surgery. Background technique [0002] Thoracic surgery is a medical specialty that specializes in the study of thoracic organs, mainly referring to the diagnosis and treatment of esophageal, lung, and mediastinal lesions. The field of breast surgery is also included in this specialty, and pulmonary surgery and esophageal surgery are the main ones. Thoracic surgery is an ancient discipline. Its formation and development have gone through about a century. At the same time, it has developed into an independent system with independent theoretical basis and interpenetrated with various disciplines from the accumulation of clinical experience. [0003] At present, with the continuous development and progress of clinical surgical techniques in thoracic surgery, the surgical method has developed from traditional open surgery to endoscop...
