Abstract

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.

Description

technical field [0001] The invention relates to a suspension type minimally invasive retractor, which belongs to the field of medical instruments. Background technique [0002] In traditional cardiovascular surgery, median sternotomy incision is mostly used, and some left posterolateral thoracic incisions are used. With the continuous improvement of the safety of cardiovascular surgery, people pay more and more attention to the beauty of intraoperative trauma incisions. In recent years, minimally invasive surgery Incision surgery is gradually favored by the majority of beauty patients. Traditional bypass surgery uses median thoracotomy. The latest treatment is small incision heart bypass surgery. In this treatment, only the intercostal opening is required. The patient has less trauma, faster recovery, safe operation, no large incision on the chest wall and beautiful appearance. . The minimally invasive small incision refers to the incision length of 6-10 cm in the surgical...
