Suspension type minimally invasive retractor

The invention belongs to the field of medical instruments, and relates to a suspension type minimally invasive retractor, which comprises a vertical supporting rod and a transverse supporting rod, the bottom of the vertical supporting rod is connected with a bed clamping device, the top end of the vertical supporting rod is connected with one end of the transverse supporting rod, a transfer device is clamped at the other end of the transverse supporting rod and connected with a blade adjusting device, and a traction blade is arranged on the blade adjusting device. An operating bed is used as a support, so that the whole device is suspended above a patient, a retraction mode is changed into an upward sternum traction mode, the height adjustable range is wide, contact with the patient is reduced, and compression on the patient is avoided. 本发明属于医疗器械领域，涉及一种悬吊式微创牵开器，包括竖支撑杆和横支撑杆，竖支撑杆底部连接有床夹装置，竖支撑杆顶端连接横支撑杆一端，横支撑杆另一端装夹有中转装置，中转装置连接有叶片调整装置，叶片调整装置上设有牵拉叶片。本发明以手术床为支撑，使得整体悬空于患者上方，牵开方式也改为向上牵拉胸骨，高度可调节范围较广，减少了与患者的接触，不会对患者造成压迫
