HUMAN BODY ANATOMICAL FEATURE COMPLIANT MINIMALLY INVASIVE CHEST DRAINAGE TUBE AND DRAINAGE SURGERY INSTRUMENTS

摘要

A human body anatomical feature compliant minimally invasive chest drainage tube and drainage surgery instrument. The drainage tube comprises a tube body (1), and the tube body (1) is sequentially provided with an outer section (101), a first bending portion (102), a transition section (103), a second bending portion (104), and an inner section (105). A section between the outer section (101) and the transition section (103) is bent by using the first bending portion (102); a section between the transition section (103) and the inner section (105) is bent by using the second bending portion (104); and at least one part of the inner section (105) is provided with an adhering arc section adhered to an inner wall (2) of a chest. By means of the drainage tube, minimal invasion of thoracic surgeries can be implemented, better conforming to the human body anatomical feature, effectively preventing luminal stenosis, and achieving a desirable drainage effect.
